One environmentally friendly alternative for weed control is to utilize cocoa plant waste (Theobroma cacao L). Can be used as a biological herbicide. The aim of this research is the effectiveness of the long fermentation time of bioherbicides from cocoa shells and beans in controlling weeds. This research used a non-factorial Randomized Block Design (RAK), consisting of 4 treatments (K (Control), M1 (7 days), M2 (14 days), M3 (21 days) and M4 (28 days)) with as many repetitions as possible. 3 times. The results of this research show that weed growth can be suppressed with cocoa bioherbicide from observation week 1 to week 3, with the highest poisoning score being 4 (Very severe poisoning; young leaves have an abnormal shape and color until they dry out and fall off until the plant dies). Symptoms of poison caused by biorherbicides include changes in leaf color from green to pale and eventually death.

Rodent pests (Rattus spp.) are one of the main threats to agricultural productivity in Indonesia, including in Bentok Darat Village, South Kalimantan. The damage caused by these pests not only reduces crop yields but also increases farmers' dependence on chemical pesticides, which pose environmental risks. To address this issue, effective and environmentally friendly pest control methods are needed. One approach employed is the installation of Owl Houses (RUBUHA) as habitats for barn owls, natural predators of rodents. This community service program aims to optimize rodent pest control by installing RUBUHA on agricultural land. The activities involve students and the Alam Subur farmer group, including training on RUBUHA installation, facility maintenance, and monitoring its effectiveness in reducing rodent populations. Observations showed that the installation of RUBUHA significantly reduced rodent attacks on agricultural land. Additionally, this method successfully increased crop productivity by up to 30% and decreased the use of chemical pesticides. In conclusion, RUBUHA installation is an innovative and sustainable solution for rodent pest control, supporting environmentally friendly agricultural practices while enhancing farmers' welfare.

Celery is a vegetable that plays an important role in meeting the nutritional needs of Indonesian people. However, celery production faces several challenges, including root knot disease caused by the nematode Meloidogyne spp. This causes a significant decrease in productivity. The biological control used is environmentally friendly biological control using Bokashi fertilizer using Supan-supan weed (Neptunia oleracea L.), EM4, PGPR and a mixture of EM4 as a decomposer with the addition of Trichoderma sp. The aim of this research is to determine the potential of supan-supan weed as an organic fertilizer together with the biological agent Trichoderma sp. in controlling root nematodes Meloidogyne spp. on celery plants. The research was carried out from January to July 2024 in Sungai Besar Village and the Phytopathology Laboratory, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The research method used a completely randomized design (CRD) using the test agents EM4, PGPR, Ecoenzyme and Trichoderma sp. which consisted of (7) treatments with (4) replications and each experimental unit consisted of (3) plants so that the total plants were 84 plants. The results showed that giving EM4, PGPR and eco-enzyme could decompose bokashi supan-supan fertilizer and giving bokashi supan-supan + EM4 + Trichoderma sp. is the best treatment for the number and severity of root knot nematodes.

Large chilies are one of the vegetable commodities that are still widely consumed and in demand, so demand in Indonesia continues to increase along with population growth. However, large chili plants are susceptible to pest and disease attacks which result in decreased production. One of the main problems in cultivating large chilies is pest attacks. Some pests that often attack chili plants include thrips (Thrips parvispinus), whitefly (Bemisia tabaci Genn), aphids (Aphis gossypii Glover), fruit flies (Bactrocera spp.) and other pests that can inhibit plant growth. Some pest control methods that can be applied include the use of yellow traps, the use of natural enemies, environmental sanitation and various other methods. This research uses paranets as a tool that is expected to reduce pest attacks that can harm chili crop yields. The method used was a Completely Randomized Design (CRD) with five paranet height treatments, namely without paranet, 50 cm, 75 cm, 100 cm and 125 cm. Each treatment consisted of four replications with four plants per experimental unit so that there were a total of 80 plants. Observations were made by recording the type and number of pests and observing damage to large chili fruit. The research results show that the use of paranets can reduce the number of pests that attack large chili plants and reduce the percentage of fruit damage due to pest attacks.

The brown planthopper (Nilaparvata lugens) is a major pest in rice cultivation. Its population can be effectively managed through biological control using the entomopathogenic fungus Beauveria bassiana. This study aimed to evaluate the effectiveness of the entomopathogenic fungus B. bassiana in controlling N. lugens under greenhouse conditions. Applications of B. bassiana at various concentrations revealed that 10⁸ conidia/mL treatment was the most effective, achieving up to 90% mortality within 7 days post-application. This treatment also recorded the lowest LT₅₀ value of 6.736 days and the highest regression value of 0.52, indicating a rapid and effective reduction in pest population. The mortality rate exhibited an increasing trend up to day five, followed by a decline as target population diminished, with cumulative mortality reaching 90% by day seven. These findings demonstrate that a concentration of 10⁸ conidia/mL is the most optimal for biological control of N. lugens using B. bassiana, both in terms of mortality rate and speed of action. The results support the potential of B. bassiana as a promising biological control agent in sustainable pest management strategies for agricultural systems.

Program Pengabdian ini bertujuan untuk mengaplikasikan penggunaan perangkap tikus semi-otomatis sebagai solusi yang efisien dan ramah lingkungan dengan mempertimbangkan keberlanjutan lingkungan. Diharapkan bahwa metode ini akan membantu menjaga keseimbangan ekosistem lokal dan mengurangi efek negatif penggunaan pestisida konvensional. Dalam pengabdian ini, perangkap semi-otomatis dipasang di pertanian Desa Bentok Darat. Evaluasi hasil pengabdian mencangkup penilaian seberapa efektif perangkap tikus, dan bagaimana perangkap berdampak pada lingkungan sekitar. Partisipasi masyarakat dalam penggunaan perangkap juga dilakukan. Hasil pengabdian menunjukkan bahwa penggunaan perangkap tikus semi-otomatis dapat secara signifikan mengurangi populasi tikus tanpa mengganggu lingkungan. Selain itu, penerimaan masyarakat terhadap penggunaan metode ini sangat positif. Hal ini menunjukkan bahwa ada kemungkinan untuk menerapkan metode ini secara lebih luas untuk mengendalikan tikus di wilayah pertanian yang lainnya yang mungkin dapat diterapkan di tempat lain.

Spodoptera frugiperda J. E. Smith (Fall Armyworm) is a pest that attacks corn and other economically important crops. S. frugiperda larvae can damage all parts of the corn plant including stems, leaves, shoots, tillers, and even the leaves of young plants can be damaged. This research aims to determine the effect of R. tomentosa leaf extract in controlling S. frugiperda. The method used was research using a Completely Randomized Design (CRD) with 6 treatments and 2 replications, resulting in 24 experimental units. The treatment involved R. tomentosa leaf extract at different doses and application methods by dipping the larvae and spraying the leaves. As a result, the life cycle of S. frugiperda lasts 32-54 days and extract doses of 10 ml (95%) and 8 ml (85%) are effective in killing larvae, while lower doses also have a significant effect.
