Abstract

Corn (Zea mays) has various health benefits derived from its carotenoid content, which gives its kernels their yellow color. Approximately 22% of this content is beta-carotene, which functions to prevent blindness due to cataracts, while xanthophyll protects cells from cancer, acts as an antioxidant, and supports the immune system and heart health. This community service activity aims to increase understanding of the optimal use of corn, specifically through the production of nutritious twistcorn snacks. This training involved the community in RT.001 RW.003 Laren Village and began with an initial questionnaire, followed by the delivery of materials on making twist corn snacks, and concluded with a final questionnaire. The material was delivered through lectures and question-and-answer discussions, which were met with enthusiasm by the participants. The results of the activity demonstrated an increase in knowledge among all participating communities following the training. Jagung (Zea mays) memiliki berbagai manfaat kesehatan yang berasal dari kandungan karotenoidnya, yang memberikan warna kuning pada bijinya. Sekitar 22% dari kandungan tersebut adalah beta karoten, yang berfungsi mencegah kebutaan akibat katarak, sementara xantofil melindungi sel dari kanker, bertindak sebagai antioksidan, dan mendukung sistem kekebalan serta kesehatan jantung. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman tentang pemanfaatan jagung secara optimal, khususnya melalui pembuatan snack jagung twistcorn yang bergizi. Pelatihan ini melibatkan masyarakat di RT.001 RW.003 Desa Laren dan dimulai dengan kuisioner awal, diikuti dengan penyampaian materi mengenai pembuatan camilan jagung twistcorn, dan diakhiri dengan kuisioner akhir. Materi disampaikan melalui metode ceramah dan diskusi tanya jawab, yang disambut dengan antusiasme peserta. Hasil kegiatan menunjukkan peningkatan pengetahuan seluruh masyarakat peserta setelah pelatihan.

Abstract

Inceptisols are widely distributed in tropical regions, including Indonesia, and are characterized by high rainfall and intensive weathering. These conditions promote severe nutrient leaching, low cation exchange capacity (CEC), and moderately to slightly acidic soil pH, thereby limiting nutrient availability, fertilizer-use efficiency, and crop productivity, particularly in oil palm (Elaeis guineensis) plantations. This study aimed to evaluate the effects of BIO SOLID 17, an organic soil conditioner derived from palm oil mill effluent (POME) sludge, on the chemical and physical properties of Inceptisol through a controlled incubation experiment. A two-month laboratory incubation was conducted using a randomized complete block design with five application rates of BIO SOLID 17 (0, 5, 10, 15, and 20 kg ha⁻¹), each with five replications. Observed parameters included soil pH, cation exchange capacity (CEC), and water-holding capacity (WHC), which were analyzed using standard methods. The results demonstrated that BIO SOLID 17 application significantly improved Inceptisol soil quality in a dose-dependent manner. Soil pH increased from strongly acidic conditions (4.85) in the control to near-neutral levels (6.19) at the highest application rate. Soil CEC also increased significantly from 34.41 to 47.49 cmolc kg⁻¹, indicating enhanced nutrient retention capacity. In addition, soil water-holding capacity increased from 46.82% to 55.81%, reflecting improvements in soil aggregation and moisture retention. Overall, BIO SOLID 17 shows strong potential as a sustainable organic soil amendment for improving the chemical and physical fertility of Inceptisol. The utilization of POME-based materials supports circular economy principles by converting agro-industrial waste into value-added agricultural inputs. Further field-scale studies are recommended to confirm effectiveness and determine optimal application rates under oil palm plantation systems.

Abstract

The extensive use of synthetic insecticides has led to environmental contamination, pest resistance, and adverse effects on non-target organisms. Botanical insecticides provide a safer alternative for sustainable pest management. This study evaluated the insecticidal activity of betel leaf (Piper betle L.) and Lantana camara leaf extracts against armyworm (Spodoptera litura).  A laboratory bioassay was conducted using three extract concentrations (30%, 40%, and 50%) arranged in a completely randomized design. Larval mortality was recorded daily for seven days after application and analyzed using ANOVA followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. Both botanical extracts significantly increased larval mortality over time. Mortality began to rise on the second day and increased sharply on the third and fourth days after application. By the fifth day, all extract treatments resulted in nearly 100% mortality, while no mortality occurred in the control. Cumulative mortality patterns indicated that Lantana camara induced a faster initial lethal effect, whereas Piper betle showed a slightly delayed but equally effective response. No significant differences were observed among concentrations, indicating that a 30% concentration was sufficient for effective control. These results highlight the potential of betel leaf and Lantana camara extracts as effective botanical insecticides for armyworm management.
