Abstract

Where rainwater is stored in the form of barrels, tubs, or ponds. Oil is as important as water for human life. Because the majority of Indonesians like fried food, cooking oil is still needed for household needs. Used cooking oil, oil produced from frying, is often used to save money, but its carcinogenic properties can cause cancer in the future. The purpose of this activity is to change the paradigm and change the paradigm of PTPN III Sei Mangke mothers. The results of this activity were 25 people, namely the age range of 28-37 years with a percentage of 36%, and the highest education level was high school with a percentage of 48% and there was a paradigm shift where previously they did not know until they understood based on the results of the questionnaire survey of the activity

Abstract

Food security remains a major challenge for Islamic boarding schools with limited land and resources. This community service program aimed to optimize the use of vacant land at the Markaz Penghafal Al-Qur'an of Yayasan Layar Dakwah to improve food security. The implemented methods included raised-bed preparation, selection of superior seeds, and efficient crop maintenance. The results showed that proper land utilization increased food productivity while reducing dependence on external food supplies. Tomatoes achieved the highest productivity at 2.25 kg/m², followed by chili peppers at 1.75 kg/m² and shallots at 1.25 kg/m². To increase the added value of the harvest, female students received training on processing tomatoes into tomato sauce with a longer shelf life, as well as product packaging and marketing techniques. The program enhanced students' skills in post-harvest processing, enabled them to produce value-added products, and created entrepreneurial opportunities that can generate additional income while supporting the food security of the Islamic boarding school.

Abstract

Aktivitas kerja pada proses produksi tempe sebagian besar masih dilakukan secara manual dan berulang, seperti mengangkat kedelai, merebus, meniriskan, serta membungkus tempe dalam waktu yang lama. Kegiatan tersebut sering dilakukan dengan postur kerja yang kurang ergonomis, seperti membungkuk, berdiri dalam durasi panjang, serta gerakan berulang pada anggota tubuh bagian atas, sehingga berpotensi menimbulkan gangguan muskuloskeletal (Musculoskeletal Disorders/MSDs). Penelitian ini bertujuan untuk menganalisis postur kerja operator di pabrik tempe menggunakan metode Ovako Working Posture Analysis System (OWAS) dan Rapid Upper Limb Assessment (RULA) untuk mengetahui tingkat risiko ergonomi serta memberikan rekomendasi perbaikan. Penelitian ini menggunakan desain deskriptif observasional. Pengumpulan data dilakukan melalui observasi langsung, dokumentasi postur kerja menggunakan foto dan video, serta pengukuran sudut tubuh pada beberapa aktivitas utama produksi. Aktivitas yang dianalisis meliputi pengangkatan kedelai, pemindahan rak fermentasi, dan pembungkusan tempe. Penilaian postur kerja dilakukan dengan metode OWAS dan RULA.Hasil penelitian menunjukkan bahwa sebagian besar postur kerja operator berada pada tingkat risiko sedang hingga tinggi. Berdasarkan analisis OWAS, aktivitas pengangkatan dan pemindahan beban termasuk dalam kategori tindakan yang memerlukan perbaikan segera. Sementara itu, hasil penilaian RULA menunjukkan skor akhir 7 yang mengindikasikan perlunya investigasi lebih lanjut dan tindakan perbaikan dalam waktu dekat.

Abstract

Limited access to laboratory testing encourages communities to assess water mainly by clarity, odor, and taste. This approach cannot adequately detect changes in physicochemical characteristics. This community engagement program developed a Community Water Quality Screening model using TDS and pH meters in Bandar Baru Village. The model integrates education, calibration, duplicate measurements, restricted interpretation, risk communication, and laboratory referral. The analytical draft uses a structured simulated dataset of 48 participants and 72 water samples from six source types. Analyses included descriptive statistics, paired t tests, McNemar tests, Kruskal-Wallis tests, chi-square tests, Spearman correlations, intraclass correlation coefficients, and linear regression. Mean literacy scores increased from 42.0 to 70.6 out of 100, a mean increase of 28.5 points (95% CI 25.9-31.1; p<.001). 85.4% of participants mastered at least eight of ten procedural steps. Of 72 samples, 44 were classified as green, 22 as yellow, and 6 as red. Water source type was associated with screening category (chi-square=33.36; p<.001; Cramer V=0.48). Duplicate measurements showed very high consistency for pH (ICC=0.998) and TDS (ICC=1.000). The model offers a practical educational framework but does not replace microbiological and comprehensive chemical testing.
