Pertumbuhan rumput laut hijau (Caulerpa sp.) pada media kultur (trays) di perairan Pulau Barrang Caddi, Kota Makassar
type: item
description: Sea grapes (Caulerpa sp.) are commonly known as lawi-lawi to locals in South Sulawesi and several other areas. This species can be consumed directly (edible seaweed) without requiring processing. Lawi has become a leading commodity for farmers in several coastal regions. This commodity can serve as an alternative livelihood for the island’s people. This study aims to look at the growth of lawi-lawi in cultural media (trays) in the coastal area of Barrang Caddi Island, Makassar. The trial took place from August to November 2024, and growth data were collected monthly on each tray, with four iterations, while also recording water quality data at regular intervals. The heavy metal content was analyzed in two seasons, namely the dry season and the rainy season. Data on water quality parameters, such as Temperature, Salinity, pH, Phosphate, and Nitrate, are within the optimal range. This shows that the surrounding water conditions can support the growth of the lawi-lawi seaweed species on the island. The specific growth rate (LPS) of lawi–lawi ranges from 0.1 to 0.5%/day. This is close to the value of LPS lawi-lawi, which is cultivated in ponds using trays. Meanwhile, the results of the heavy metal content test on the lawi–lawi sample showed a number that was far below the SNI threshold, so it was very safe to consume.

Estimasi kesesuaian perairan untuk marikultur berbasis kualitas air dan pendekatan spasial-temporal di Pulau Karampuang, Sulawesi Barat
type: item
description: Mariculture activities play a significant role in contributing to the country's foreign exchange, as many of its products are exported abroad. Mamuju Regency, situated in West Sulawesi Province, is part of the eastern region of Indonesia and boasts vast potential for mariculture due to its abundant natural resources. However, farmers face several challenges, particularly oceanographic factors such as large waves, variations in freshwater input, and nutrient concentrations from land-based activities. These factors can negatively impact aquaculture media and alter oceanographic conditions, potentially threatening cultivation. The goal of this study was to examine the spatial and temporal dynamics of oceanographic conditions and assess the feasibility of waters for mariculture activities. The research was conducted in the waters around Karampuang Island in Mamuju Regency, using a descriptive quantitative approach. This involved determining sampling stations, measuring water quality both in situ and ex situ, analyzing data to assess the suitability of the waters for mariculture, and creating a GIS-based land suitability map. The results show that the water conditions in Karampuang Island are pretty dynamic, with varying water quality parameters observed, indicating diverse suitability for mariculture. For seaweed cultivation, station 3 was categorized as quite suitable, while stations 1 and 2 were considered appropriate. However, for KJA system cultivation, only station 1 consistently supports cultivation. Further studies are needed to monitor the water quality periodically and conduct cultivation trials to optimize farming activities.

Peran vegetasi dalam meningkatkan kualitas aksesibilitas di ruang terbuka publik (studi kasus: Taman Vatulemo)
type: item
description: Urban parks, as public open spaces, serve as areas that support social interaction and enhance the quality of life for the community. These parks feature vegetation that not only enhances their aesthetic appeal but also provides ecological benefits. Vegetation also contributes to visitor comfort and improves park accessibility. However, suboptimal vegetation planning can hinder accessibility for certain groups, such as individuals with disabilities, the elderly, and children. This study aims to analyze the role and impact of vegetation on accessibility in Vatulemo Park, Palu City. The research begins with field observations, followed by spatial analysis using GIS to examine the distribution of vegetation and circulation patterns within the park. Additionally, a landscape design evaluation is conducted based on Universal Design principles and accessibility standards for green open spaces. The findings indicate that the distribution of vegetation in Vatulemo Park does not fully support accessibility. Shaded areas along circulation paths and jogging tracks are still insufficient, making the park less comfortable for visitors, especially between 10:00 AM and 4:00 PM WITA. Moreover, the lack of vegetation around seating areas and gathering spaces reduces the park’s ecological function and user comfort. Therefore, recommendations are necessary to improve vegetation placement within the park, aiming to increase greenery along circulation paths and jogging tracks. The selection of plant species should also be adjusted to avoid obstructing visitor activities and comfort. Furthermore, chosen vegetation should not hinder accessibility, and user-friendly pathways should be provided for individuals with special needs. By implementing these strategies, Vatulemo Park is expected to become a more inclusive, comfortable, and ecologically sustainable public space for the residents of Palu City.

Kemampuan antibakteri daun rambutan (Nepheliium lappaceum Linn) terhadap bakteri Vibrio sp. secara in vitro
type: item
description: Vibrio sp. is an opportunistic pathogenic bacterium that causes vibriosis in fish, shrimp, and seaweed. The use of synthetic antibiotics is everyday; however, resistance is difficult to prevent. The advantages of using natural antibiotics include their availability, environmental friendliness, and cost-effectiveness. This study aimed to utilize a natural material, specifically rambutan (Nephelium lappaceum L.) leaf extract, as a candidate for testing its antibacterial activity against Vibrio sp. A phytochemical analysis of the rambutan leaf extract was conducted to identify the presence of bioactive compounds that inhibit bacterial growth. The extraction was performed through maceration using 70% ethanol as the solvent. The extract was then diluted in a series of concentrations ranging from 100% to 3.125%. Antibacterial activity was tested using the disk diffusion method on Thiosulfate Citrate Bile Salt Sucrose (TCBS) agar medium. The results showed a potent inhibitory effect at the 100% extract concentration, with an inhibition zone diameter of 24.675 ± 0.53 mm. Potent inhibition was also observed at 75% and 50% extract concentrations, with inhibition zones of 19.95 ± 1.56 mm and 19.225 ± 4.63 mm, respectively. Phytochemical analysis of the rambutan leaf extract revealed the presence of several bioactive compounds, including alkaloids, steroids, flavonoids, saponins, and tannins. The study concluded by calculating the extract yield to assess the efficiency of rambutan leaf extraction using ethanol, yielding 7.16 ± 0.14%.

Pertumbuhan bibit tanaman karet dan perbandingan biaya pemupukan pada pengaplikasian pupuk daun dan pupuk akar
type: item
description: Fertilization can be applied through the leaves and roots, which have different characteristics and can complement each other. Foliar fertilizer suitable for use in rubber plant nurseries, other than Bayfolan, is Glow Green. This study aims to determine the growth of a rubber plant nursery using foliar fertilizer and root fertilizer, and to compare the fertilization costs. Research from April to September 2023 at the Bogor-Getas Unit Experimental Field, Salatiga. The experimental design used a randomized block design with 9 treatments and 3 replications. Treatments consisted of a control without fertilization, 50% root fertilizer, 100% root fertilizer, and a combination of root fertilizer at three dose levels (0%, 50%, 100%) with Bayfolan and Glow Green. Glow Green can reduce 50% dose of root fertilizer with plant height growth, stem diameter, and dry weight that are not significantly different compared to 100% root fertilizer and higher than 50% root fertilizer. The dry weight in the 50% root fertilizer + Bayfolan treatment was lower than in the 100% root fertilizer treatment. Treatment with 50% root fertilizer + Glow Green and 100% root fertilizer + Bayfolan showed higher relative agronomic effectiveness compared to 100% root fertilizer as the standard fertilization (RAE 108% and 105%), with fertilization costs of 89.8% and 117.5%. Glow Green is recommended for large-scale use in rubber nurseries, reducing fertilization costs by 10.2% and reducing the root fertilizer dose by 50%. At the same time, Bayfolan is applied without reducing the root fertilizer dose.

Komposisi proksimat, mineral dan logam berat Sargassum polycystum di perairan Pulau Payata, Kabupaten Pohuwato
type: item
description: Sargassum polycystum is a type of brown seaweed that grows naturally in the waters of Payata Island, Pohuwato Regency. Although it is abundant, its use by coastal communities is still minimal. This type of seaweed has excellent potential as a food source due to its rich content of various essential nutritional components, including protein, carbohydrates, and minerals. This study was conducted to determine the nutritional content and safety of S. polycystum consumption through proximate analysis, mineral content, and heavy metals. Samples of fresh S. polycystum are taken directly from their natural habitat, dried, and analyzed in the laboratory using standard methods. The results of the analysis showed that dried S. polycystum had a moisture content of 12.80%, an ash content of 31.87%, a fat content of 0.60%, a protein content of 10.54%, a crude fiber content of 7.42%, and a carbohydrate content of 44.20%. The main mineral content found included calcium at 0.72%, magnesium at 216 mg/kg, sodium at 213 mg/kg, potassium at 114 mg/kg, and iron at 690 mg/kg. Some other micromineral elements, such as chromium, are also detected in small amounts, while selenium, zinc, boron, and cobalt are below the detection limits of the tool. In addition, heavy metal test results showed that the levels of lead, cadmium, and mercury in S. polycystum were <0.030 mg/kg, <0.005 mg/kg, and <0.001 mg/kg, respectively, which means they are still well below the safe threshold for consumption. Based on these results, it can be concluded that Sargassum polycystum in the waters of Payata Island, Pohuwato Regency, not only has a reasonably high nutritional content but is also relatively safe for consumption. This potential opens up opportunities for its use as an alternative food ingredient or raw material for functional food products, offering economic value to coastal communities

Pengaruh suplementasi tepung jintan hitam dan tepung daun mengkudu terhadap organ reproduksi puyuh betina
type: item
description: Quail (Coturnix coturnix japonica) is an egg-producing poultry species whose optimal egg production relies on reproductive health, which can be supported by adding herbal supplements to the feed. This study investigated the potential of black cumin meal (BCM) and noni leaf meal (NLM) on the reproductive quality of female quail. Ninety-six heads of quails aged 66 days were maintained for 28 days with the following treatment: T0= Basal Feed (BF); T1= BF + 1% BCM + 3% NLM; T2= BF + 2% BCM + 3% NLM; T2= BF + 2% BCM + 2% NLM; T3= BF + 3% BCM + 1% NLM. Two head quails in each unit were necropsied to observe the parameters of the study, such as: weight and length of the oviduct, oviduct presentation, reproductive organ presentation, ovary weight, number and weight of yellow follicles, and weight of white follicles. The data were analyzed using a completely randomized design (CRD) with four treatments and three replications. The results showed that BCM and NLM supplementation only affected the weight of the oviduct and ovary (P<0.05); otherwise, there was no effect (P>0.05). No additional protein source is responsible for this finding; instead, the antioxidant content of the supplement serves to maintain livestock health. A combination of BCM and NLM can be recommended as a feed supplement at a rate of up to 1-3%.

Analisis hubungan klorofil dan pembagian asimilat dari aplikasi biosaka dalam pertumbuhan vegetatif tanaman melon
type: item
description: Biosaka contains elicitor compounds that stimulate the physiological activity of plants, including increased chlorophyll content and enhanced efficiency of assimilate distribution. This study aims to examine the effect of elixitors in biosaka on leaf chlorophyll content and its relationship with the distribution of assimilates in the vegetative growth phase of melon plants. The research was conducted using an experimental method with a non-factorial Complete Random Design (CRD). The single factor in the form of biosaka concentration consists of six levels: B0 = 0 mL L⁻¹, B1 = 10 mL L⁻¹, B2 = 20 mL L⁻¹, B3 = 30 mL L⁻¹, B4 = 40 mL L⁻¹, and B5 = 50 mL L⁻¹. Each treatment was repeated four times, with each repetition consisting of three plants. The results showed that the application of biosaka at various concentrations had no significant effect on all observed parameters. Nevertheless, there is a substantial increase in plant length by up to 93% towards the end of the vegetative phase. A positive correlation was found between plant length and assimilate distribution to the crown (r = 35–47), as well as between leaf area and plant length and assimilate distribution to the crown (r = 36–77). This indicates that the application of biosaka contributes to the increase in physiological activity of plants, through an increase in leaf area that supports the process of photosynthesis and assimilation in the upper part of the plant.

description: Aphids are polyphagous insects commonly found on various plants, including citrus plants. The association between aphids and citrus plants plays a role as pests and vectors of citrus plant diseases, particularly Citrus tristeza virus (CTV). Various aphid species have been reported as vectors of CTV, including Aphis gossypii, Toxoptera aurantii, and T. citricidus. So far, no information has been available on aphid species associated with citrus plants in Southeast Sulawesi. Therefore, this study aimed to identify aphid species associated with citrus plants. The research method used was observation and collection of aphids found colonizing citrus plants. The collected aphids were then brought to the laboratory for detection using the polymerase chain reaction (PCR) technique. The study results showed that the aphid species associated with citrus plants was Aphis citricidus. The PCR technique successfully detected the genome of aphid vector samples from Konawe and South Konawe (700 bp). This information is a fundamental basis for controlling CTV in mainland Southeast Sulawesi.

Pertumbuhan dan kelangsungan hidup larva udang vaname (Litopenaeus vannamei) pada pemberian Thalassiosira sp. yang diperkaya omega-3 dari minyak cumi
type: item
description: The most critical stadia of shrimp larval development are the zoea and mysis stadia. Zoea stadia has a lower survival rate compared to other stadia, even death in zoea stadia can reach 90% before developing into mysis. Efforts to improve shrimp survival can be made by improving the quality of feed nutrients, one of which is by giving Thalassiosira sp. enriched with omega-3 from squid oil. This study aimed to determine the effect of Thalassiosira sp. enriched with omega-3 from squid oil on the growth and survival of vaname shrimp larvae (Litopenaeus vannamei). The experimental design used is a complete randomized design (CRD) consisting of 4 treatments and 3 replicates, namely treatment K: Control (without enrichment), A: Enrichment of Thalassiosira sp. with squid oil 0.05 ml/L, B: Enrichment of Thalassiosira sp. with squid oil 0.07 ml/L, and C: Enrichment of Thalassiosira sp. with squid oil 0.1 ml/L. Vaname shrimp larvae used at the zoea stadia were reared until the mysis stadia by observing their growth and survival. The results showed that feeding Thalassiosira sp. enriched with omega 3 from squid oil at a dose of 0.1 ml/liter (treatment C) gave a better effect than the other treatments, where larval length growth was 5.1 mm and weights of about 1.12 mg, survival was 85% with fat content in the feed after enrichment of 13.69%.

Perbandingan fekunditas dan produksi naupli induk udang windu (Penaeus monodon) yang diberi pakan hati sapi dan cacing laut
type: item
description: The increase in tiger shrimp production (Penaeus monodon) needs to be balanced with the availability of high-quality seeds from broodstock that obtain feed with good and balanced nutritional content. The limited number of sea worms as a natural feed is still dependent on the population in nature and the price is relatively expensive. Therefore, alternative feed ingredients are needed that function as substitute feed for sea worms. This study examines the potential of cow liver as a substitution of sea worms in tiger shrimp broodstock feed to increase fecundity and naupli production. The method carried out to test was the administration of beef liver pieces and sea worms as mother feed in the morning with a dose of 6.25% of the parent biomass. The frequency of feeding is carried out 4 times a day, namely at 07.00, 11.00, 14.00 and 18.30, with a dose of 25% of the shrimp biomass per day for 14 days of production at the Barru Shrimp Hatchery. The results of the activity showed that the sows fed cow liver showed better results, namely producing an average fecundity of 370,238 grains/head and an average production of 178,550 naupli/head. This result was higher than that fed by sea worms, which was an average fecundity of 296,253 grains/broodstock and an average production of 140,039 naupli/broodstock. Cow liver is a source of vitamin A that can improve the reproductive performance of broodstock shrimp, measured by fecundity and naupli production. The results of this study are information for shrimp hatchery units to use cow liver as a substitute for sea worms in broodstock feed because of its high nutrition and relatively low price in order to increase the production of tiger shrimp seeds.

type: item
description: Okara or soybean pulp is a by-product of processed soybeans that has a high nutritional content of protein and food fibre. The physical and chemical modification process is needed for okara flour to improve the ability of water absorption so that it can be applied to chicken nugget products. This study aimed to determine the impact of modification type on the water absorption ability of okara flour produced and the impact of modification type and percentage of modified okara flour substitution on the texture and sensory properties of chicken nuggets produced. The research procedure started by making okara flour treated with modification types (autoclaving-cooling, acid hydrolysis, combination of acid hydrolysis, and autoclaving-cooling). Modified okara flour was applied to chicken nuggets with a percentage of flour substitution of 5% and 10%. The results of flour analysis showed that the three types of modified okara flour can decrease the ability of water absorption compared to the control. The results of chicken nugget analysis showed that the three types of modification and the percentage of okara flour substitution significantly affected the texture values of hardness, cohesiveness, and gumminess but did not significantly affect the value of springiness and sensory properties of the product.

Pemetaan indeks pertanaman lahan sawah menggunakan citra satelit landsat 8 di Kabupaten Tanah Datar (studi kasus: Kecamatan Sungai Tarab)
type: item
description: Increasing national rice production requires several strategies, including expanding the planting area by creating new rice fields, increasing land productivity, and expanding the harvest area by increasing the planting index (IP). The Tanah Datar Regency area produces lowland rice with different production in each sub-district. This difference in rice production results occurs due to differences in harvested area which is influenced by the rice planting index. One way to identify rice IP is by utilizing remote sensing technology through vegetation indices to see rice growth phases on Landsat 8 satellite images. A reliable vegetation index calculation in determining rice growth phases is the Enhanced Vegetation Index (EVI). This research aims to determine the paddy field planting index in Sungai Tarab District. This research utilizes Landsat 8 satellite imagery in 2021 and 2022. This research uses quantitative descriptive analysis through interpretation of Landsat 8 satellite imagery recorded in 2021 and 2022 and field survey data. This research produces results of the rice growth phases in 2021 and 2022, maps of the distribution of planting indices in 2021 and 2022, and several factors that influence differences in planting indices. Based on the distribution of the planting index in 2022, it has increased compared to 2022, namely there are three classes of planting index IP 100, IP 200, and IP 300. Meanwhile, the irrigation network is the main factor in influencing the IP of rice in Sungai Tarab District.

type: item
description: The utilization of fishery by-products has been recognized as an effective alternative solution to address the challenges of feed ingredient availability. One of the fishery by-products that holds potential for feed production is Gosse. However, there are challenges in using Gosse as duck feed due to its nutrient content, which is not yet optimal to meet the nutritional needs of ducks. This study aims to analyze the changes in the nutritional quality of Gosse after the addition of EM4. The research was conducted at the Polytechnic of Agriculture in Pangkajene and Islands, with proximate analysis covering moisture content, ash content, crude protein, crude fiber, and crude fat, carried out in the laboratory of the institution-fiber, and crude fat, carried out in the laboratory of the institution's laboratory. The method employed was a Completely Randomized Design (CRD) with four treatments and three replications. The treatments were: P0 (Gosse without the addition of EM4), P1 (5% EM4 addition), P2 (10% EM4 addition), and P3 (15% EM4 addition). The results showed that the best nutrient quality for moisture content and crude fat was found in P0 (without EM4), while the best ash content was observed in P2 (10% EM4 addition). The optimal results were achieved in P3 (15% EM4 addition) for crude protein and fat, which requires further testing at higher levels.

The results of the observations were then analyzed descriptively. Data on physical parameters of the waters showed conditions suitable for coral biota, including pH 8.01, temperature 30°C, salinity 27.67 ppt, current flow 0.07 m/s, brightness 100%, and depth 7 m. Coral species observed included Acropora cervicornis, Montipora digitata, Pocillopora damicornis, Porites compressa, and Echinopora horrida. Health disorders in corals consisted of disorders by algae, sponges, barnacles, fish bites, bleaching, shellfish, and fan worms (Sabellidae). The type of disease found was White Band Disease (WBD) in Acropora cervicornis coral with a frequency of six colonies. The presence of health disorders and diseases in cultivated coral fragments requires special attention because it can affect the survival rate and long-term growth of corals

Manajemen pakan dan kualitas air pada pemeliharaan larva ikan kerapu cantang (Epinephelus fuscoguttatus >< Epinephelus lanceolatus)
type: item
description: Cantang grouper (Epinephelus fuscoguttatus >< Epinephelus lanceolatus) is one of the leading export commodities in Indonesia. The sustainability of cantang grouper farming must be supported by the availability of quality seeds. Efforts to produce cantang grouper fry can be carried out with proper maintenance of larvae. This study aims to determine the technical management of feed and water media in maintaining cantang grouper larvae. The type of feed used is natural feed and artificial feed with doses adjusted to the age of the larvae. The types of natural feed given to cantang grouper larvae are Nannochloropsis oculata, Rotifer, and Artemia sp. The range of water quality parameters, namely temperature 30.5-31 oC, pH 7.8-8.2, salinity 33-34 ppt, and DO 3.51-4.27 ppm is still optimal for maintaining cantang grouper larvae. Feed, and water quality management can support the development of canting grouper larvae with a Hatching Rate (HR) value of 48%-72% and a Survival Rate (SR) of 16%-18%.

Pengukuran keparahan gejala penyakit kuning dan kandungan nitrogen tanaman cabai terinfeksi Virus Gemini berbasis spektral biosensor
type: item
description: Gemini Virus infection yellow leaf curl virus causes morphological damage such as leaf malformation, small leaves, curved leaves, and stunted plants, and affects the nitrogen content and leaf area of chili plants. The variation of symptoms is quite high so its measurement is quite difficult. The same thing with measuring the nitrogen content of plants can only be done in the laboratory. However, along with the development of digital technology, these measurements can be done directly in the field, including measuring the leaf area index of plants. The purpose of the study was to measure the severity of Gemini Virus disease symptoms, nitrogen content, and leaf area of chili plants infected with Gemini Viruses. Using the ImageJ Software application, samples of chili plants infected with Gemini Viruses were recorded randomly on chili plantations in the Muna and Buton Islands. The variables observed were the severity of Gemini Virus symptoms, nitrogen concentration, and leaf area of chili plants infected with Gemini Viruses. The results showed that there was a tendency that the higher the severity of Gemini Virus symptoms, the lower the nitrogen content and the smaller the leaf area index of chili plants.

Pengaruh penambahan jenis dan konsentrasi hidrokoloid terhadap sifat fisik dan kualitas pemasakan mi kering bebas gluten
type: item
description: Noodles are one of the food products frequently consumed by the Indonesian people. The main ingredient for making noodles is wheat flour, which contains gluten, one of the causes of celiac disease. The experiment involved making gluten-free noodles from local flours, namely sago flour, yellow sweet potato flour, and mung bean flour, with the addition of hydrocolloids to resemble the characteristics of conventional noodles. The research aims to determine the effect of adding guar gum and xanthan gum on the physical properties and cooking quality of gluten-free dry noodles. This research was conducted using a qualitative and quantitative approach with a factorial completely randomized design. Data analysis was conducted using the Analysis of Variance (ANOVA) test with the Minitab 20 application. The testing showed a significant effect, so further testing was conducted using the BNJ/Tukey test at the 5% level. The research results indicate that the noodle dough's molding ability has not yet formed perfectly, although the strands of noodles are still fragmented. Visually, gluten-free dry noodles are yellowish-brown in color. The concentration of xanthan gum and guar gum has a significant effect (α≤0.05) on the resulting moisture. The concentration of xanthan gum and guar gum has a significant effect (α≤0.05) on the cooking time obtained, and xanthan gum and guar gum have a significant effect (α≤0.05) on water absorption, shrinkage, cooking time, and the resulting cooking time.
