Hamsia — 2025-12-29

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.

Andi Masriah — 2025-12-18

This study aims to analyze the protein content of suckermouth catfish (Pterygoplichthys sp.) egg meal and to evaluate its potential as a fish feed ingredient. Egg meal samples were analyzed using Uv-Vis spectrophotometry with a standard albumin curve approach using linear regression. The analysis showed that the protein content of suckermouth catfish egg flour ranged from 35 to 37%. This value indicates a fairly high protein content, suggesting its potential as an additional protein source in fish feed formulations. In addition, suckermouth catfish are an invasive species that negatively impacts aquatic ecosystems. Therefore, utilizing its eggs as a feed raw material not only provides economic added value but also helps control the population of this invasive species. The use of sapu-sapu fish egg meal can be a sustainable and economical alternative for providing feed raw materials, especially to support fish growth in intensive aquaculture systems.

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.

Corn cob waste (tumpi jagung) has potential as a livestock feed due to its abundant availability; however, it is characterized by low crude protein content and high crude fiber content, which limits its utilization. Therefore, efforts are needed to reduce its crude fiber content to improve its nutritional value for livestock. This study aimed to evaluate the effect of corn cob fermentation using MA-11 and EM-4 bioactivators on crude fiber (CF), acid detergent fiber (ADF), and neutral detergent fiber (NDF) contents. The study was conducted in February 2025 at the Laboratory of the Faculty of Agriculture, Univet Bantara. The experimental design used was a Completely Randomized Design (CRD) with a one-way pattern, consisting of three treatments and eight replications. The treatments were as follows : 250 g corn cob + 2 g urea + 5 cc molasses; 250 g corn cob + 5 cc MA-11 + 2 g urea + 5 cc molasses; 250 g corn cob + 5 cc EM-4 + 2 g urea + 5 cc molasses. All treatments were incubated for 7 days. The observed variables were crude fiber (CF), ADF, and NDF contents. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT). The results showed that fermentation of corn cob waste using MA-11 and EM-4 significantly reduced crude fiber, ADF, and NDF contents. Unfermented corn cob contained CF 6.36%, ADF 39.64%, and NDF 50.59%. Fermentation with MA-11 resulted in CF 4.33%, ADF 33.96%, and NDF 48.33%, whereas fermentation using EM-4 produced CF 3.70%, ADF 32.88%, and NDF 46.78%. The EM-4 bioactivator was more effective in reducing fiber components, with decreases of 0.63% in crude fiber, 1.08% in ADF, and 1.55% in NDF compared to MA-11.

Abri — 2025-12-17

Continuous use of chemical fertilizers hurts soil conditions. The soil hardens quickly, is less able to retain water, and quickly becomes acidic, thus reducing plant productivity. Efforts are needed to use organic fertilizers from agricultural waste and biofertilizers from potential rhizosphere fungi. The purpose of this study was to obtain an effective formulation and combination of organic fertilizers from agricultural waste with 2 species of Rhizosphere fungi isolated from Tana Toraja aromatic rice plants, namely Aspergillus sp and Trichoderma sp, on the growth and production of Tana Toraja aromatic rice plants. This study was designed as a two-factor factorial experiment arranged in a Randomized Block Design. The first factor was three levels: Rhisosphere Fungus C0 = Without Fungus Application, C1 = Rhisosphere Fungus 5 g / liter of water. C2 = Rhisosphere Fungus 10 g / liter of water. The second factor was liquid organic fertilizer/compost from agricultural waste at three levels: K0 = No liquid fertilizer, K1 = 500 ml liquid fertilizer/10 liters of water, and K2 = 1000 ml liquid organic fertilizer/10 liters of water. Nine treatment combinations were replicated thrice, each with two plants, resulting in 54 experimental plots. The results showed that applying Trichoderma and Aspergillus fungi at a dose of 10 g/liter had the best effect. Meanwhile, applying liquid organic fertilizer from cocoa shells and straw at 1000 ml/10 liters of water had the best effect. The best combination/interaction effect was found between the application of 10 g/L rhizosphere fungi and 10 g/L liquid fertilizer, and 1000 ml/L liquid organic fertilizer on the observed components of plant height, number of tillers, number of productive tillers, number of grains/panicle, and panicle length.

Fluctuations in Soil Temperature and Moisture in Various Types of Agricultural Land Use: Implications of Soil Physical Properties

Riskawati — 2025-12-18

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.

Eko Hary Pudjiwati — 2025-12-31

Marginal land has low productivity due to its limited soil fertility, especially in terms of nitrogen (N) availability. The use of nitrogen-fixing bacteria and shrimp waste as alternative organic fertilizers can increase nitrogen use efficiency in sweet corn (Zea mays saccharata), which is an important food commodity. This study aims to determine the ability of nitrogen-fixing bacterial isolates to increase N nutrient use and their effect on the growth and production of sweet corn when applied together with shrimp waste. This study was conducted using a randomized block design (RAK) with a treatment of 20 tons/ha of shrimp waste and chemical fertilizer (50% Urea + 100% SP-36 + 100% KCl) with the addition of nitrogen-fixing bacterial isolates, consisting of 5 treatments and 4 replicates, namely no fertilizer, shrimp waste, and nitrogen-fixing bacteria. Other treatments were control, which was 100% Urea + 100% KCL + 100% SP-36; then isolate BPN1; isolate BPN2; isolate BPN3. The results of the study show that the application of nitrogen-fixing bacteria and shrimp waste technology packages can increase soil organic carbon content, nitrogen nutrient uptake, nitrogen nutrient uptake efficiency, and agronomic efficiency of sweet corn crops on marginal land. In addition, this technology can also reduce urea fertilizer use by up to 50%. This technology has the potential to be an environmentally friendly solution to support sustainable agriculture on marginal land.
