Abstract

The condition of agricultural productivity in Kecamatan Panca Rijang shows fluctuations from time to time. It is important to know the extent to which farmers are satisfied with the performance of agricultural extension workers, considering that the role of extension workers has a direct relationship with agricultural production, especially in the research area. This study aims to analyze the level of farmer satisfaction with the performance of agricultural extension workers in supporting sustainable agricultural practices in Timoreng Panua Village. The population in this study amounted to 629 farmers, with a sample size of 42 respondents selected through specific techniques. Data was collected by distributing questionnaires to farmers living in Timoreng Panua Village. The data obtained were then analyzed quantitatively using the Importance Performance Analysis (IPA) method. The results showed that the level of farmer satisfaction with the performance of agricultural extension workers was in the very satisfied category, with an IPA score of 92.55%. The five performance attributes must be maintained based on the IPA Cartesian diagram. They contribute significantly to farmer satisfaction: participation, social interaction, community development, increased farmer income, and production efficiency. These five attributes are important indicators in assessing the effectiveness of extension workers' performance in the field and as benchmarks in developing sustainable agriculture programs in the future.

Abstract

This research aims to determine the characteristics of slow-release fertilizer based on corncob biochar which is enriched with various nutrient sources (NPK, SP36, cow urine and Azotobacter). Research methods include making biochar through pyrolysis and nutrient impregnation. Fertilizer characterization includes analysis of nutrients, material fractions, biochar stability, and functional groups using spectra (FTIR). The results of the four analyzes carried out showed that the SRFbiochar+SP36+cow urine formulation provided the best results in retaining nutrients and water.  The nutrient content produced by SRFbiochar+SP36+cow urine, namely N(0.35%) P (0.63%), K (0.7%), Corganic (6.49%), volatile content (15%) strengthened by the ultimate results which show high nutrient content (C=10.09%, N=0.35%), which is explained by the formation of hydroxy functional groups (O-H) in tire 3444.87 and carboxy groups on the band 1635.64. These results indicate that the SRF-BiocharSP36+bovine urine formulation has the potential to be developed as a slow-release fertilizer to increase fertilization efficiency in dry land for sustainable soil fertility improvement.

Abstract

The aim of this study was to analyze the characteristics of turtle nests, environmental conditions, and turtle nesting activities. The methods used were field observation techniques and descriptive qualitative data analysis. During the 2025 nesting season (February–August), 11 nests were identified, located approximately 30 m from residential areas. These nests contained a total of 1,442 eggs, with a hatching success rate of 94%, resulting in 1,362 chicks, 53 eggs did not hatch, and 27 chicks died. Analysis of environmental factors showed that nest temperatures ranged from 27 to 31 °C, pH ranged from 5.5 to 7, and humidity levels fluctuated between 50 and 74%. The width of the beach in the intertidal zone is 50 m, with elevations ranging from 6.23 to 11.72%, while the supratidal zone presented elevations from 0.82 to 6.04%. The composition of the sediments varies in weight from 10.08 to 641 g, with fine sand being the dominant particle size (60.05%). The coastal vegetation is dominated by 6 plant species.

Abstract

Vegetable waste has the potential to be animal feed, which is optimally utilized if fermented first. Vegetable waste is a source of fiber, and when fermented with fish meal waste, it can increase its nutritional quality. This study aimed to determine the physical quality of fermented vegetable waste supplemented with fish meal waste with different percentages. The study used a completely randomized design (CRD) consisting of four treatments and four replications. The treatments were the percentage of fish meal waste supplementation of 0, 5, 10, and 15%. The parameters observed were the pH value and organoleptic of fermented vegetable waste, including aroma, texture, color, and the presence of fungi. The results showed that fermented waste feed with different fish meal supplementation had a significant effect (P <0.05) on the variables, color, and aroma of fermented vegetable waste and had no significant effect (P>0.05) on the variables of pH value, texture, and the presence of fungi. Supplementation of 10% fish meal waste has a yellowish-green color and a solid texture and does not show the presence of fungi. Supplementation of 10% fish meal waste has a pH value of around 4.3 and shows a distinctive aroma of fermented products. Based on the study's results, fermented vegetable waste feed with 10% fish meal waste supplementation showed the best physical quality, including pH value, texture, color, aroma, and the presence of fungi.

Abstract

Rainfed lowland fields represent marginal agroecosystems that are highly vulnerable to drought stress due to their full dependence on rainfall as the primary water source, often resulting in reduced rice productivity. Therefore, adaptive and high-yielding varieties are required to sustain production under these conditions. This study aimed to evaluate the morphological characters and yield performance of five rice varieties, namely MR 20, Kusuma, Inpari 32, IR-64 Jumbo, and Pak Tiwi 2, cultivated in rainfed fields during the dry season. The experiment was arranged in a Randomized Block Design (RBD) with three replications. Observed parameters included vegetative traits, generative traits, biomass, and grain yield per hectare, which were analyzed using ANOVA, LSD test at 5%, and correlation analysis. The results showed that Inpari 32 excelled in vegetative traits and yield components such as panicle length and 1000-grain weight. MR 20 performed best in total grain number, filled grain number, and grain weight per hill, while IR-64 Jumbo produced the longest panicle and the highest yield (7.5 t·ha?¹), comparable to MR 20 (7.3 t·ha?¹). Correlation analysis indicated that grain yield was positively associated with panicle length, total grain number, filled grain number, and root biomass. Overall, MR 20 and IR-64 Jumbo are recommended as adaptive and high-yielding varieties for rainfed lowland fields in the dry season, whereas Inpari 32 is superior in yield components and grain quality.
