Abstract

Corn is an important food commodity that susceptible to pest attacks such as armyworm (Spodoptera frugiperda). This invasive pest attacks the growing points of corn plants and causes decreased productivity. Supporting biological research on this pest, the development of artificial feed is crucial considering the limited natural feed. This study aimed to evaluate the effect of artificial diet formulations on the preferences of S. frugiperda larvae. Three formulations with different compositions are studied in this research. Instar 3 larvae were subjected to a preference test to determine the rapid response of the larvae and the weight of the feed consumed (daily consumption). The preference test was carried out in duration 1, 2, 4, 6, and 24 hours. The results showed that Formula 3, which uses natural ingredients such as baby corn and corn sprouts, has the highest initial attractiveness (30% in 1 hour). The physical and chemical characteristics of artificial diet affect the preferences of larvae with formula 3 being the most effective for rapid response, and formulas 1 and 2 being more stable for continuous use. The highest daily consumption of larvae was in formula 3 (0.066 ± 0.027 grams). However, it was not significantly different from formula 1 (0.058 ± 0.029 grams). The use of artificial feeds in the laboratory rearing of S. frugiperda offers a viable alternative to natural feeds, with Formula 3 showing a high initial preference, Formula 1 remaining attractive over time, and Formula 2 showing lower consumption, likely due to its efficient nutritional composition, as evidenced by feeding activity through visible bite marks and feed perforations.

Abstract

The increasing expansion of palm oil plantations can exacerbate climate change due to high deforestation rates and increased CO2 emissions. This study aims to identify carbon sequestration through oil palm frond biochar as a mitigation strategy for CO2 emissions and land degradation. This research conducted at Palm Oil Plantation on Siluman B, Labuhanbatu District.  This study using a Factorial Randomized Block Design with two factors, 3 × 2, and 5 replications, resulting in 30 experimental units. The main factor is biochar A0 = No biochar, A1 = 1.5 kg, A2 = 3.0 kg. The second factor is the method of biochar application which includes B0 = Incorporation into soil, B1 = Applied on the soil surface. Biochar significantly increases soil carbon stocks by nearly double, proving its role in carbon sequestration. Application of biochar on the surface and incorporation into soil have the same efect to increase soil carbon sequistration. Biochar fundamentally improves soil fertility by increasing the Cation Exchange Capacity, total N content, and the availability of essential base cations, while lowering the C/N ratio to a more ideal level. The method of incorporating biochar into the soil proved superior for enhancing CEC, making it the recommended practice.

Abstract

The increase on rice plant growth can be done through the application of organic and inorganic fertilizers, as well as the use of appropriate varieties. This research aimed to examine the effect of a combination of organic and inorganic fertilizer doses and the use of varieties on improving rice plant growth and nutrient level. The research was conducted from June to August 2025 located in Sudimoro Village, Megaluh Subdistrict, Jombang Regency. This research used a factorial randomized block design (RBD) with two factors and three replications. Factor 1 is a combination of biological and inorganic fertilizer doses consisting of 9 levels of treatment, namely: 100% inorganic fertilizer + no biological fertilizer (P1), 75% inorganic fertilizer + no biological fertilizer (P2), 50% inorganic fertilizer + no biological fertilizer (P3), 100% inorganic fertilizer + 5 ml biological fertilizer (P4), 75% inorganic fertilizer + 5 ml biological fertilizer (P5), 50% inorganic fertilizer + 5 ml biological fertilizer (P6), 100% inorganic fertilizer + 10 ml biological fertilizer (P7), 75% inorganic fertilizer + 10 ml biological fertilizer (P8), and 50% inorganic fertilizer + 10 ml biological fertilizer (P9). Factor 2 is the rice plant varieties, namely: Inpari 32 (V1) and Ciherang (V2). The observations conducted included growth observations, namely plant height, number of leaves, number of tillers and dry weight of plants observed at 15, 30, 45, and 60 days after planting and NPK level of plants observed at 60 days after planting. The results showed that the combination of 100% inorganic fertilization + 10 ml of organic fertilizer generally increased plant height, number of leaves and dry weight of rice plants. The use of the Ciherang variety resulted in better plant height, number of leaves and dry weight of rice plants compared to the Inpari 32 variety. The use of a combination of inorganic and organic fertilizer had a significant effect on increasing the number of tillers of rice plants of the Inpari 32 variety compared to the Ciherang variety. The nitrogen content of rice plants (1.17 to 1.99%) is included in the deficiency category, while the phosphorus content (0.14 to 0.31%) and potassium (1.45 to 2.22%) are included in the excess category, where the addition of biofertilizer has an effect on increasing the nitrogen, phosphorus and potassium content of rice plants compared to without biofertilizer.

Abstract

Mung bean is Indonesia's important legume crop after soybean and peanut, and it can be grown as a primary crop or an intercrop. The purpose of this study was to compare disease development and yield on mung bean fields grown under a spreading and dibbling cropping system in Kedungwringin Village, Jatilawang District, Banyumas Regency, Central Java. Data was collected from farmers through interviews and weekly disease observation in six mung bean fields. The type of disease, disease incidence, and severity were also determined using data obtained directly from the field. The study discovered five fungi and virus: powdery mildew (Erysiphe sp.), stem rot (Sclerotium rolfsii), leaf rust (Uromyces sp.), leaf spot (Cercospora sp.), and yellow mosaic disease (Begomovirus). The incidence of such diseases was ranging from 1% up to 85%, with the yellow mosaic disease having a very low incidence. There is no significant difference of disease intensity on both system. Leaf spot was the major disease with severity increasing gradually from 11.11% to 43.17%. Several insect pests and predators were discovered in fields. Considering the higher pod production in response to the disease occurrence, the dibble cropping system is recommended as the better mung bean farming strategy.

Abstract

Agriculture is a vital sector that is a food security sector. However, agricultural productivity is still often hampered by the lack of monitoring of soil conditions, which results in inaccurate fertilizer application. The development of an Internet of Things-based fertility measuring tool is an innovative solution to overcome this problem. With the ability to provide accurate data on N, P, K and pH nutrient levels quickly, this tool allows farmers to fertilize precisely. The research method used is Research and Development which has stages of literature study, system design, web application development, calibration and testing: data analysis and improvement. Sandy soil samples L1, L3, and L4 nitrogen error 6–7%, phosphorus error 8–10%, potassium error 6–10%, and neutral soil pH slightly acidic error 5%. Clay soil samples L2, L6, L7, and L9, nitrogen and potassium content error 5–6% and 6–7%. Phosphorus error around 7%. Soil pH ranges from 3–5%, indicating slightly acidic conditions. Clay samples L5, L8, and L10 contain 5–10% nitrogen, 6–9% phosphorus, 6–8% potassium, and 3–5%. Therefore, the results of N, P, and K measurements on sandy, loamy, and clay soils should be interpreted with caution and confirmed through laboratory tests.
