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.

Abstract

Freshwater lobster (Cherax quadricarinatus) is a fishery commodity with high economic value, and market demand continues to increase. However, one of the main challenges in cultivating freshwater lobsters is the low survival rate of fry, especially in the early stages of development. This research aims to optimize the dosage of a combination of amino acids and dissolved glucose to meet the nutritional needs of freshwater lobster fry and support their survival. This research was carried out at the Agriculture, Livestock, and Fisheries Greenhouse, Muhammadiyah University of Parepare, using freshwater lobster fry from captive breeding. The research method used was a Completely Randomized Design (CRD) with four treatment doses of a combination of amino acids and dissolved glucose, namely: A) 100 ppm glucose + 250 ppm amino acids, B) 150 ppm glucose + 200 ppm amino acids, C) 200 ppm glucose + 150 ppm amino acids, and D) 250 ppm glucose + 100 ppm amino acids, each with three replications. The parameters explained are the chemical composition of the body, including protein, fat, fiber, and BETN content. A combination dose of 250 ppm glucose and 100 ppm amino acids is most effective in improving the nutritional quality of freshwater lobsters (Cherax quadricarinatus). The results of this study show the highest protein content (14.28%), fat content (0.89%), and fiber content (0.7%), all of which are important for the growth and health of lobsters. Meanwhile, the combined dose of 100 ppm glucose + 250 ppm amino acids yielded the best BETN (4.95%). Overall, the 250-ppm glucose and 100 ppm amino acid combination is optimal for improving the chemical composition of the lobster's body.

Abstract

Climate change impacts all aspects of life including agriculture, which influences land management practices, soil temperature and moisture, and land use types. This research aims to identify soil temperature and moisture fluctuations across various agricultural land cover types and their relationship to soil physical properties. This research was conducted in Mariat District, Sorong Regency, on four types of land use and was selected intentionally (purposive sampling). The coordinates of each type of land are: Rice Field 075°77’35’’E 98°88’12”SL; Garden land: 075°75’82”E, 98°88’09”SL; Agroforestry land: 075°74’30”E, 98°88’01”SL; and Unproductive land 075°76’30”E, 98°88’80”SL. Measurement of soil temperature and humidity using environment-meter for 30 consecutive days and soil sampling was carried out (intact soil samples and disturbed soil samples) to identify the physical properties of the soil. The research results showed fluctuations in soil temperature and moisture content across each land use. In general, the average morning temperature was 27.2°C, midday 32°C, and evening 27.5°C. Meanwhile, the average soil moisture content was 79.5% in the morning, 74% in the afternoon, and 81% in the evening. The physical properties of the soil in the four land uses are different in soil texture, soil color, available water, permeability, and aggregate stability. The use of rice fields and dry fields has the same temperature and humidity. However, the use of gardens and agroforestry land tends to differ because variations influence plant vegetation. Temperatures too high and humidity too low can worsen soil conditions, causing physical degradation that affects agricultural productivity and soil sustainability.

Abstract

Integrated farming-based agroindustry is a system for processing organic fertilizer that combines various agricultural activities, including crop farming, livestock, aquaculture, and other related sciences within a single land area that maintains an internal energy flow. This study aims to identify and describe farmers' perceptions of the use of liquid organic fertilizer and to formulate development strategies for integrated farming-based agroindustry in Pinrang Regency. The methods used in this research are qualitative descriptive analysis and Interpretative Structural Modeling (ISM). The results indicate that liquid organic fertilizer requires a more consistent application process and has a stronger odor compared to chemical fertilizers, leading many farmers to continue using chemical fertilizers. The ISM analysis identifies two primary strategies that are most effective for implementation: enhancing the role of agricultural extension workers and developing processing technology. These strategies involve intensive farmer engagement through regular field visits and training to facilitate technology adoption, as well as the provision of farming facilities and infrastructure as part of the technology development process introduced by extension agents.

Abstract

Rarit is a processed product originating from the island of Lombok, in the form of meat sheets that are marinated with salt and sour spices, then dried in the sun. The development of quality and attractive rare products for consumers requires the right method in the use of additives and preservatives because they can affect consumer health. This study aims to analyze the optimization of beef rare quality through the integration of the use of Parangi Acid (Dialium indium) and vacuum marinator technology. The research design used a Completely Randomised Design Factorial (4x2) with 4 replications. The first factor was parangi acid marination level, consisting of 0%, 15%, 30%, and 45%, and the second factor was marination time using a vacuum marinator tumbler (15 minutes and 30 minutes). The results showed that parangi acid and marination time using a vacuum marinator had a significant effect (P?0.05) on microbiological and organoleptic quality. The best treatment was rare marinated using paraffin acid with a concentration of 45% for 15 minutes. Processing rare using parangi acid was effective in improving the organoptic and microbiological quality of rare beef. Parangi acid has potential as a natural preservative in rare beef.
