Abstract

Agricultural land has been experiencing a decline in fertility due to the continuous and unbalanced use of chemical fertilizers, which negatively affects soil conditions and the surrounding environment. Organic fertilizers offer an environmentally friendly and sustainable alternative. One of the primary sources of organic fertilizer is livestock manure, which is utilized through the GESEKU program (Gerakan Sejuta Kotak Umat). This study aims to analyze the nutrient content of livestock manure-based organic fertilizer and the soil nutrient status following its application under the GESEKU program. This research method was carried out by purposive sampling, collecting soil samples from agricultural fields that had received organic fertilizer applications in eight districts across Blora Regency. The results showed that the fertilizer had a pH range of 7.02–8.99, nitrogen content of 2.17–2.94%, and organic carbon content between 15.00–32.60%. Total nitrogen content in the soil was categorized as moderate (0.22–0.33%). Available phosphorus ranged from low to very high (12.89–45.13 ppm), while exchangeable potassium was categorized as low to moderate (0.27–0.45 me/100g). The soil’s organic carbon content was classified as very low to low (0.54–1.66%). Based on the findings, it can be concluded that the soil in the sampled locations remains in an optimum condition for rice cultivation, indicating that the use of organic fertilizer from the GESEKU program contributes positively to maintaining soil fertility

Abstract

Bango soy sauce is one of the popular brands that ranks first in the Top Brand Award, but has experienced a decline in the Top Brand Index value starting in 2021, indicating a decrease in consumer repurchase intention. This decline is related to the weakened perceived quality and brand image of Bango soy sauce. Thus, the purpose of this study was to investigate the impact of brand image and perceived quality on repurchase intention among Bango soy sauce product users in Surabaya City. Surabaya City was purposefully selected as the research location, with a focus on modern retail. A total sample size of 100 respondents was determined using the Cochran formula, and the accidental sampling method was used as the sampling technique. SmartPLS 4.0 software is used for data analysis using Partial Least Squares based on Structural Equation Modeling (PLS-SEM). The analysis's findings demonstrate that repurchase intention is positively and significantly influenced by perceived quality and brand image.

Abstract

Perum Perhutani, the South Banyuwangi Forest Management Unit (KPH) produces pine sap as a commodity for non-timber forest products. The collection of pine sap in the FMU area involves members of the community around the forest. The level of eavesdropping revenue is greatly influenced by the productivity of tapping. Therefore, this study aims to find out the level of pine sap productivity that affects the income of tapers and the level of welfare of tapers. The determination of the plots was carried out by purposive sampling so that 4 plots were selected: 19A-1, 19C, *26E-1, and *26E-3. The determination of the plot using a sampling intensity of 1% was obtained with 16 plots determined by the plot demonstration method. Data collection was carried out by census method. The results of the study showed that (1) the average productivity of pine sap in RPH Karangharjo was 6.10 grams/tree/day. (2) Eavesdropping income who only works as a eavesdropping has an average income of Rp. 15,624,000 per year, while eavesdropping with additional work has an average total income of Rp. 17,627,142 per year. (3) Based on World Bank standards, 100% of eavesdropping is classified as prosperous, but according to the Banyuwangi Regency MSE, there are only 52.38% who are prosperous and the rest are not. Further research is needed related to factors that can affect the productivity of pine sap on eavesdropping revenue.

Abstract

Maize (Zea mays) is one of the most important staple crops, alongside rice. However, its production has been continuously declining in recent years. The primary cause of this decline is the deteriorating soil condition, including increasingly acidic soil pH and very low levels of organic carbon and organic matter. This study aims to determine the effective application dosage of biochar derived from corncob waste to improve soil fertility and maize production. The experiment was conducted using a Completely Randomized Design (CRD) in polybags. There were five treatments with five replications: Control (P1), corncob biochar 32 g/polybag (P2), corncob biochar 64 g/polybag (P3), corncob biochar 128 g/polybag (P4), and corncob biochar 256 g/polybag (P5). The parameters observed included soil pH, organic carbon, organic matter, plant height, cob length, and number of dry kernels. The results showed significant differences among treatments, with the best performance found in treatment (P4), corncob biochar 256g/polybag. There was a noticeable improvement before and after the application, with soil pH increasing from 4.25 to 6.75, organic carbon from 1.4% to 3.6%, and organic matter from 2.42% to 6.15%. For plant growth parameters, the best results were also achieved at the biochar application 256g/polibag (P4). Therefore, the higher the amount of corncob biochar applied, the more effective it is in enhancing the growth and production of maize.

Abstract

One of Indonesia's most valuable commodities is scallions, a type of onion known as Allium ascalonicum L. Wilt disease, caused by Fusarium sp., poses significant challenges to shallot production. Curled, light-green leaves, along with complete plant death, are symptoms of this disease, which reduces harvest yields. To manage Fusarium wilt in shallots, this research aims to assess the efficacy of antagonistic fungi, namely Trichoderma sp. and Gliocladium sp. The research used in vitro testing to determine how well the fungus inhibited the growth of Fusarium sp., and in vivo studies to assess how well the control worked in the real world. The active chemicals that were generated were identified by Gas Chromatography-Mass Spectrometry (GC-MS) analysis. With an inhibitory power of 77%, Trichoderma sp. topped the list, followed by Gliocladium sp. with 75%.

Abstract

Tomato plants are easy to cultivate because they have high adaptability and a relatively short lifespan. Efforts to develop tomatoes at the farmer level are carried out by improving soil nutrient conditions by providing various types of organic and inorganic fertilizers in order to accelerate the growth process, development and production of tomato. Adequate nutrients will stimulate leaf and stem growth, budding, chlorophyll formation, increase nutrient absorption, and have an important effect on increasing yields. This research was conducted in the dry land of Kaniti village from July to September 2024. The tools and materials used in the study were hoes, watering cans, digital scales, rulers, knapsack sprayers, calipers, cameras, hybrid tomato seeds, polybags, bokashi, curacron (insecticide), NPK Mutiara, stakes, and ropes/twines. The study used a Completely Randomized Design (CRD), with one independent variable in the form of a dose of NPK Mutiara compound fertilizer at four treatment levels: no fertilizer (control), 2 g (H1), 4 g (H2), and 6 g (H3) per plant. The dependent variables included growth parameters—plant height, stem diameter, and number of productive branches—measured at 14, 28, 42, and 56 days after planting (DAP), with data from 56 DAP analyzed as a representation of final growth. Production parameters consisted of weight and number of fruits per plant, measured at 72, 78, 85, and 90 DAP, with the average value or total harvest used in the analysis. Significant differences between doses of NPK Mutiara compound fertilizer were analyzed using one-way ANOVA. Further tests were conducted using post-hoc (DMRT). The results showed that treatment H3 (6g NPK Mutiara/plant) gave the best performance in most growth and production parameters, indicating a positive dose-response relationship within the tested range. Application of NPK Mutiara of 6g/plant—with repetitions on days 0, 14, and 28 DAP—significantly increased tomato growth and yield compared to the control, although it was not significantly different from the 4g dose in the 5% LSD test. The results of further tests confirmed that treatment H3 (6g NPK Mutiara/plant) was significantly superior (group A) to H2, H1, and H0 in increasing plant height and production parameters (weight and number of fruits). This indicates a positive dose-response relationship within the range of doses tested, with a dose of 6 grams/plant proving to be the most effective in increasing tomato productivity.

Abstract

Corn (Zea mays L.) is one of the leading food commodities in Indonesia whose availability is often not optimally met. The decline in productivity in agricultural land caused by pest attacks is a very damaging and detrimental factor. Biological control using biological agents in the form of entomopathogenic fungi is an alternative choice for controlling corn pests that is quite cheap but environmentally friendly so as to maintain the balance of the environmental agro-ecosystem. The purpose of this research is to identify the types of entomopathogenic fungi from exploration using the insect bait method in several lowland soil samples that have great potential as biological agents to control Spodoptera frugiperda pests that attack corn plants. The results of the study showed that the lowland soil samples of Tojan, Klungkung and Saba, Blahbatuh, Gianyar did not find symptoms of entomopathogenic fungi that infect the insect pest S. Frugiperda, while the lowland soil samples of Padanggalak, Sanur found symptoms of entomopathogenic fungi that infect the insect pest S. Frugiperda. The results of the pathogenicity test and macroscopic and microscopic identification showed that the characteristics of the isolates refer to the fungus Aspergillus flavus.

Abstract

A popular practice for weed management in soybean cultivation is the use of Siam weed (Chromolaena odorata L.) organic mulch and oxyfluorfen herbicide. This study aimed to determine the appropriate dose of Siam weed mulch and oxyfluorfen for effective weed suppression, improved growth, and yield of soybean. The experiment was conducted from July to September 2025 in Lawe Sagu Hulu Village, Lawe Bulan Subdistrict, Aceh Tenggara, Aceh, Indonesia. A non-factorial randomized block design (RBD) was employed with 12 treatments; D0:control; D1:12.5 organic mulch; D2:14.0; D3:15.5; D4:17.0; D5:18.5 t ha?¹; D6:300 oxyfluorfen herbicide; D7:500;  D8:700; D9:900; D10:1100 g a.i. ha?¹; and D11:continuous mechanical control, replicated four times. Experimental plots measured 2.5 × 2.5 m, with Siam weed mulch applied as 10 cm chopped biomass spread evenly on the soil surface, while oxyfluorfen was applied at 1 DAS. Observed variables included weed cover percentage, plant height, number of pods, and 100-seed weight. Results showed that Siam weed mulch at 17 t ha?¹ significantly increased soybean height at 20 and 30 DAS. Oxyfluorfen at 900 g a.i. Ha-¹ effectively reduced weed cover and decreased the number of pods per plant.

Abstract

Rice productivity is greatly influenced by the level of soil fertility, which is the main source of nutrients. Rice fields in Soa District, Ngada Regency, consist of irrigated and rain-fed rice fields managed differently. Excessive use of chemical fertilizers without the addition of organic matter is feared to reduce soil quality, so a study is needed to determine the status of soil fertility in both types of land. The study was conducted through a field survey with soil sampling at six locations, three each in irrigated rice fields and three in rain-fed rice fields. At each location, five sample points were taken using the diagonal method at a depth of 0–20 cm. Samples were analyzed at the Soil Chemistry Laboratory of Nusa Cendana University to determine pH, Organic Carbon, Total Nitrogen, Available Phosphate, Available Potassium, Cation Exchange Capacity (CEC), and Base Saturation (BCC). The analyzed data were then evaluated using the matching method and t-test to see differences between land types. The analysis results showed that the irrigated land is classified as fertile to very fertile with high P and K content, very high CEC and BCC values, and medium Organic Carbon. In contrast, rainfed land showed varying fertility levels from low to high, with the main constraints being low organic carbon, phosphorus, and potassium. The t-test showed no statistically significant differences, but agronomically, the differences between locations were quite clear. This study emphasizes the importance of adding organic matter and implementing balanced fertilization, especially in rainfed land, to maintain nutrient availability and support sustainable rice production.
