Abstract

The Bombay duck (Harpadon nehereus), a common bycatch species found in various coastal fisheries, has experienced a global population decline. Studies on its reproductive biology, distinguishing between males and females, are still limited, particularly in the Strait of Malacca. This study aimed to investigate sexual dimorphism in the reproductive biology of H. nehereus, including body length distribution, length-weight relationship, growth pattern and coefficient, condition factor (K), hepatosomatic index (HSI), sex ratio, and gonadal maturity stage (GMS). Each specimen was morphometrically measured and dissected to collect data on total length, body weight, growth pattern, condition factor (K), hepatosomatic index (HSI), and gonadal maturity stage (GMS). Linear regression analysis was performed to examine the length frequency distribution, length-weight relationship, and growth pattern, as well as to evaluate the condition factor, hepatosomatic index, sex ratio, and gonadal maturity stage. The results showed that the total length of males ranged from 150 to 309 mm, and that of females from 198 to 309 mm. The length-weight relationship of both sexes showed a positive correlation, indicating positive allometric growth. The condition factor (K₁=3.2753% and K₂=2.9142%) and hepatosomatic index (HSI= 0.00717%) indicated that the physiological status of H. nehereus was generally healthy, with a condition factor value of 1-3. The sex ratio showed a higher number of males than females, with an average ratio of approximately 2.10:1. Analysis of gonadal maturity stages showed that most males were at stage I (immature), while most females were at stage IV (mature). Keywords: bombay duck, condition factors, hepatosomatic, length-weight

Abstract

The Ternate coast is a tropical marine area characterized by warm temperatures and high salinity, supporting various marine organisms, including borers that cause wood biodeterioration. These organisms inflict severe damage on wood-based coastal infrastructure, including piers, stilt houses, and vessels. This study aimed to identify marine borer species in Ternate and determine the infested coastal wood types. The research was conducted from March to June 2024 using wood baiting and direct observation methods. The baiting test was performed at Dufa-dufa and Falajawa Beaches using tusam (Pinus merkusii) and rubberwood (Hevea brasiliensis), assembled according to SNI 7207:2014 and submerged in the sea. Direct observations were carried out across nine beaches in Ternate City by collecting wood samples showing signs of attack. Specimens were preserved in 70% alcohol and identified under a microscope in the laboratory. The study identified four marine borer species: Bankia carinata (Mollusca), alongside Chelura insulae, Sphaeroma terebrans, and Cenoloba obliteralis (Arthropoda). B. carinata infested the bait wood, whereas the other three species were present in wood collected during coastal observations. Damage levels on tusam and rubberwood were higher at Falajawa Beach than at Dufa-dufa Beach. Marine borer activity was supported by aquatic conditions featuring temperatures of 20–31°C, salinity of 30–35 ppt, and pH levels of 7.9–8.4. Infested coastal wood species included mangrove apple (Sonneratia sp.), beach calophyllum (Calophyllum sp.), and sea hibiscus (Hibiscus sp.). Keywords: bait wood, crustaceans, mollusca, observation

Abstract

This study investigates the cultural significance of momosad in promoting sustainable agroforestry land management and a green economy in Bolaang Mongondow, North Sulawesi. Although agroforestry has been acknowledged for its environmental and economic benefits, research on the incorporation of local cultural values into sustainable land management within rural agricultural communities is limited. This research employed a qualitative ethnographic method, conducted in-depth interviews and field observations with 15 agroforestry producers on the site. The data were evaluated thematically to discover momosad values that are still applied in land management. The findings indicate that values such as togetherness, social agreement, dependency among farmers, and cultural motivation are still prevalent in agroforestry practices, particularly among nuclear families and close relatives. These behaviors are expressed in communal effort, shared resource utilization, and the forging of social bonds among farming communities. These findings show that local cultural values are still important in promoting sustainable farming practices and community-based agroforestry management. This study emphasizes the need of incorporating local knowledge into the creation of green economy strategies in rural farming communities. Keywords: agroforestry, green economy, local wisdom, momosad, sustainable land management

Abstract

Indonesia's soybean output averages 0.6−0.8 t·ha⁻¹, far lower than the potential yield of 2−3 t·ha⁻¹. Imports still account for more than 60% of national need. The prevalence of dryland areas with low fertility and inadequate water-holding capacity remains a major barrier to enhancing domestic soybean productivity. This study evaluated how bioameliorants improved soil chemical characteristics and soybean productivity. A randomized block design was used with six treatments: P1 (bioameliorant mixture at 30 t·ha⁻¹), P2 (bioameliorant mixture at 20 t·ha⁻¹), P3 (chicken manure at 30 t·ha⁻¹), P4 (cow manure at 30 t·ha⁻¹), P5 (control, no bioameliorant), and P6 (rice husk charcoal at 30 t·ha⁻¹). Each treatment had three replications. The criteria studied were vegetative growth, physiological indices, leaf area index (LAI), net assimilation rate (NAR), relative growth rate (RGR), and yield components. Data was evaluated using analysis of variance (ANOVA) and HSD at 5%. The results demonstrated that bioameliorants considerably increased growth and yield over the control. P2 had the most leaves (204 per plant), leaf area (5,417.94 cm²), and dry biomass (168.72 g/plant), but P1 had the highest grain output (2.8 t·ha⁻¹). The control yielded just 1.2 t·ha⁻¹, and the 1000-seed weight was consistent among treatments (about 175 g). Bioameliorant mixes, especially at 20−30 t·ha⁻¹, improve soil quality, increase soybean growth, and double yield in dryland conditions, while also supporting sustainable waste utilization and soil health restoration. Keywords: chicken manure, cow dung, rice husk charcoal, soil amendment, soil fertility

Abstract

The development of high-fiber oat-based products can be innovated by adding fish protein concentrate (FPC) to create healthy snacks. The application of ribbon fish FPC remains underexplored. This study aims to evaluate the use of ribbon fish FPC combined with oats to create food products. The optimal product formulation for nutritional characteristics was determined through a hedonic test to measure consumer preference. The research method used a Completely Randomized Design in the manufacture of FPC and oat fish products. The best FPC extraction results from the extraction frequencies (one, two, three times) were selected as fortification ingredients. Variations in the treatment of adding FPC to products with concentrations of 0%, 10%, 20%, and 30%. Nutritional composition testing uses the AOAC method for food analysis, including ash content using dry ashing, protein using the Kjeldahl method, fat using Soxhlet extraction, and carbohydrate content calculated based on the difference. The results of the study showed that the best ribbon fish FPC contained high protein (82.40%) with low fat content (1.15%) with a frequency of three extractions. The hedonic test on the product showed that 20% FPC (P2) obtained the highest score for the analysis of nutritional value in 100 grams, which has the potential to provide an efficient low-calorie satiety effect (321.24 kcal), high protein (22.75 g), sufficient dietary fiber (5.64 g), and low sugar (1.39 g). The use of local fishery resources is a potential raw material for food product diversification. Keywords: nutrition, oat, protein, ribbon fish, snack

Abstract

Lettuce (Lactuca sativa L.) is a popular leafy vegetable grown in hydroponic systems such as the fertilizer Film Technique (NFT) because of its excellent water and fertilizer efficiency. However, even under intense cultivation circumstances, transitory nutritional imbalance, reduced root activity, or poor nutrient absorption can impair plant growth and output. Foliar fertilization can thus be used as an additional fertilizer supply approach to improve plant performance in NFT systems. The purpose of this study was to evaluate how different foliar fertilizer concentrations affected the growth and yield of curly lettuce produced in an NFT hydroponic system. The experiment used a Completely Randomized Design (CRD) with eight different dosages of commercial foliar fertilizer (Gandasil D®: 0, 0.5, 1, 1.5, 2, 2.5, 3, and 3.5 g L⁻¹). Each experimental unit consisted of three replications and three plants. The fertilizer was applied weekly from transplanting to harvest in a greenhouse NFT system. Plant height, leaf number, leaf area, chlorophyll content, root volume, and fresh weight were among the parameters measured. Foliar fertilizer significantly increased plant height, number of leaves, leaf area, root volume, and plant fresh weight (p < 0.05), but had no significant effect on chlorophyll content. Plants performed best at 3.5 g L⁻¹, with a 105% increase in fresh weight compared to the control group. Plant fresh weight was substantially related to leaf area, number of leaves, and root volume. To boost lettuce growth and productivity in NFT hydroponic systems, apply 3.5 g of foliar fertilizer per L. Keywords: biomass, curly lettuce, nutrient management, plant yield, soilless cultivation

Abstract

This study analyzes Farmers’ Terms of Trade (FTT) among rice and oil palm farmer households in Kutai Kartanegara Regency using a household-level approach. Specifically, it examines the structure and magnitude of the index of prices received by farmers (IT) and the index of prices paid by farmers (IB) as the main components of FTT. A quantitative survey was conducted among 165 farmer households, consisting of 105 rice-farming households and 60 oil palm smallholder households. FTT was calculated as the ratio of IT to IB, while the Laspeyres index was applied to measure changes in price components relative to the base year. The results show that the FTT of rice farmers varied across districts, ranging from 84.15 to 107.98, with an average of 99.33. This indicates that rice farmers generally experienced a near-equilibrium welfare condition, although several households remained vulnerable to production cost increases and output price fluctuations. In contrast, the FTT of oil palm farmers ranged from 82.49 to 115.47, with a higher average of 103.23, reflecting relatively stronger purchasing power despite inter-district disparities. These findings highlight income disparities between farmer groups and emphasize the need for policies that stabilize farm output prices, reduce production cost burdens, and strengthen farmer institutions to improve household welfare. Keywords: farmers, household, oil palm, rice, welfare

Abstract

Coffee berry disease (CBD), caused by the fungus Colletotrichum spp., is one of the main obstacles to coffee cultivation and production globally. To date, no comprehensive research has been conducted on the incidence and severity of CBD in Indonesia. The study aimed to determine the current status of CBD and its correlation to agricultural practices. A planned investigation of coffee plantations was carried out in Central Java and West Java, Indonesia, from April to July 2024. Direct observation was conducted to evaluate the incidence and severity of CBD in 42 coffee plantations (Coffea arabica and Coffea canephora) in Bogor, Bandung, Sukabumi, Cianjur, Temanggung, Banjarnegara, and Wonosobo. Data on agricultural practices were collected through field observations and interviews with farmers. Climate data were obtained from the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG). In C. arabica plantations, the highest incidence of CBD was obtained in Bogor (West Java) and Temanggung (Central Java), with the maximum disease severity recorded in Bogor. In the C. canephora plantation, the incidence of CBD is relatively high, ranging from 86.67% to 100% across all study sites, with the highest disease severity also recorded in Bogor at 14.91%. The results of the correlation analysis showed that older plants and flat topography were associated with higher disease incidence, whereas shading was significantly correlated with increased CBD severity. Keywords: Colletotrichum, disease severity, shade, topography

Abstract

Deforestation in the inland regions of West Sulawesi has been increasing alongside the expansion of patchouli plantations and the high dependence of the patchouli oil distillation industry on fuelwood. This study aims to analyze changes in vegetation cover, identify the spatial distribution and hotspots of deforestation, and delineate deforestation-prone zones associated with patchouli plantation and distillation activities in Mamasa Regency. The analysis employed a spatial approach based on Geographic Information Systems (GIS), utilizing the Normalized Difference Vegetation Index (NDVI) derived from Sentinel-2 imagery for 2018 and 2025, vegetation change analysis (ΔNDVI), and Kernel Density Estimation (KDE) to identify deforestation hotspots. The results indicate that dense vegetation cover has experienced a significant reduction and spatial fragmentation, particularly in areas with high accessibility. Deforestation is concentrated in the central and eastern parts of Mamasa Regency and shows a strong spatial association with patchouli plantation and distillation locations. The highest deforestation intensity occurred during the 2021–2022 period, coinciding with increased patchouli oil prices that stimulated large-scale land clearing. High to very high deforestation-prone zones are generally located around patchouli distillation sites and areas subjected to intensive land use pressure. Based on IFAS and EFAS analyses, deforestation mitigation strategies should focus on transitioning to renewable energy, agroforestry-based commodity diversification, strengthening forest governance, and rehabilitating degraded areas to support sustainable forest management. Keywords: deforestation, fuelwood, patchouli, SWOT analysis, West Sulawesi

Abstract

This study aimed to evaluate the performance of the Sarana Makmur Dairy Farmers Cooperative (Koperasi Peternakan Sarana Makmur/KPSM) from the perspective of five institutional aspects, namely cooperative institutional aspects, business aspects, financial aspects, benefits to members, and benefits to society. The research was conducted at KPSM located in Cangkringan District, Sleman Regency, Special Region of Yogyakarta, in October 2025 using a descriptive quantitative approach. The study employed primary data obtained through interviews with key cooperative informants and secondary data derived from cooperative documents and reports. Cooperative performance was analyzed based on the Regulation of the Minister of Cooperatives and SMEs No. 21/Per/M.KUKM/IX/2015 and the Regulation of the Deputy for Institutional Affairs No. 04/Per/Dep.1/III/2018. The results showed that KPSM achieved a total performance score of 1,180, placing it in the “Good Quality” category with an AAB rating. The institutional, financial, and member benefit aspects demonstrated good to very good performance, reflecting sound governance, stable financial conditions, and tangible benefits for members’ welfare. However, the cooperative business aspect and benefits to society were assessed as moderately good and require further improvement, particularly in strengthening inter-member business linkages and optimizing the distribution of surplus. Overall, KPSM has functioned effectively as both an economic and social institution, although there remains room for improvement to enhance its competitiveness and long-term sustainability. Keywords: cooperative performance, dairy cooperative, institutional aspects, Sarana Makmur cooperative, Yogyakarta
