Abstract

Energy needs are increasing, while the energy sources used so far have come from petroleum, natural gas and coal (fossil fuels) which are non-renewable and the amount always decreases from time to time. Energy sources derived from renewable fuels are a solution to this problem. One type of product from renewable energy sources derived from vegetable oil is biodiesel (methyl ester). Biodiesel is a monoalkyl ester of long chain fatty acids contained in vegetable oils or animal fats for use as diesel engine fuel. The implementation stage of this activity begins with the preparation of raw materials in the form of preparation of used cooking oil and filtering. The second stage is dissolving caustic soda (2-3 g) into methanol liquid (5:1 methanol water). The third stage is mixing the oil with a solution of methanol and caustic soda into a bottle and allowed to stand for 24 hours, this stage aims to separate the glycerol content in the oil. The fourth step is to separate the oil with solid glycerol and transfer it to an empty container to be mixed with warm water, this aims to remove excess methanol liquid in the oil, let stand for 24 hours. The last step is to separate the oil from the mixing water. From the results of this experiment, a ready-to-use biodiesel liquid was obtained.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan menerapkan teknologi tepat guna berbasis pemanfaatan abu sekam padi sebagai pengganti sebagian semen dalam pembuatan paving block di Desa Sendang Mulyo, Kabupaten Lampung Tengah. Permasalahan utama yang dihadapi masyarakat adalah belum optimalnya pengelolaan limbah sekam padi serta tingginya ketergantungan terhadap semen sebagai bahan konstruksi utama. Metode yang digunakan adalah pelatihan dan pendampingan teknis yang meliputi sosialisasi, praktik pembakaran sekam padi secara terkendali, pencampuran material, dan pencetakan paving block dengan substitusi abu sekam padi sebesar 10% dari berat semen. Evaluasi dan monitoring dilakukan melalui observasi langsung, diskusi dengan peserta, serta analisis situasi pascapelatihan. Hasil pengabdian menunjukkan bahwa masyarakat mampu mengaplikasikan teknologi tersebut secara mandiri tanpa kendala teknis berarti. Temuan ilmiah menunjukkan adanya perubahan persepsi masyarakat terhadap limbah sekam padi menjadi sumber daya bernilai guna, potensi pengurangan penggunaan semen, serta peluang efisiensi biaya produksi paving block. Kegiatan ini juga meningkatkan pengetahuan dan keterampilan masyarakat dalam mendukung pembangunan infrastruktur desa yang ramah lingkungan dan berkelanjutan.

Abstract

Keterbatasan ketersediaan air merupakan permasalahan utama pada lahan pertanian tadah hujan yang berdampak pada rendahnya produktivitas dan kesejahteraan petani. Kondisi ini juga dialami oleh masyarakat Desa Munjuk Sempurna, Kecamatan Kalianda, Kabupaten Lampung Selatan, yang sebagian besar menggantungkan mata pencaharian pada sektor pertanian namun belum didukung oleh infrastruktur irigasi yang memadai. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberdayakan masyarakat desa melalui pembangunan sumur bor dan sistem irigasi pipa sebagai solusi penyediaan air bagi lahan pertanian tadah hujan. Metode pelaksanaan kegiatan dilakukan dengan pendekatan partisipatif, meliputi survei lapangan, kajian teknis hidrogeologi, perencanaan dan pembangunan sumur bor, pemasangan sistem irigasi pipa, serta sosialisasi dan pelatihan pengoperasian kepada masyarakat. Hasil kegiatan menunjukkan bahwa sumur bor yang dibangun mampu menyediakan pasokan air yang relatif stabil dan sistem irigasi pipa dapat mendistribusikan air secara merata ke lahan pertanian. Selain menghasilkan luaran fisik berupa infrastruktur air, kegiatan ini juga meningkatkan pengetahuan dan kapasitas masyarakat dalam mengelola sumber daya air secara mandiri. Dengan demikian, pembangunan sumur bor dan sistem irigasi pipa berbasis pemberdayaan masyarakat terbukti efektif dalam mendukung peningkatan produktivitas pertanian tadah hujan dan berpotensi meningkatkan kesejahteraan masyarakat desa.

Abstract

The implementation of construction projects often faces delays that are difficult to avoid, as experienced in the construction of the City X Hospital Building, where there was a discrepancy between the initial plan and actual field implementation, resulting in a two-week delay in weekly progress. This study aims to analyze time and cost efficiency and compare the effectiveness of alternatives between extending working hours and adding labor using the Time Cost Trade Off method. This research is comparative, comparing the total cost and duration of the project for both acceleration alternatives. The total project cost under normal conditions was recorded at IDR 7,289,386,643.45 with a duration of 86 days until the completion of the third floor. The analysis shows that extending working hours by 1 to 4 hours resulted in costs of IDR 14,584,817,481; IDR 21,871,659,072; IDR 28,672,701,971; and IDR 34,564,808,294, with cost efficiency of –100.08%, –200.05%, –293.35%, and –374.18%, respectively. The project duration was reduced to 64, 50, 41, and 36 days, with time efficiency of 26%, 42%, 53%, and 58%. Meanwhile, the alternative of adding labor resulted in a total cost of IDR 13,660,989,499 with a cost efficiency of –87.41% and a project duration of 64 days (26% time efficiency). Based on these results, both extending working hours by one hour and adding labor showed the most efficient outcomes, but overall, adding labor was considered more optimal as it achieved the same acceleration with the lowest total cost.
