Abstract

Permasalahan sampah rumah tangga merupakan salah satu persoalan lingkungan yang terus mengalami peningkatan akibat pertumbuhan penduduk, perubahan pola konsumsi, serta rendahnya tingkat pengelolaan sampah dari sumbernya. Sampah organik yang berasal dari aktivitas rumah tangga seperti sisa makanan, limbah dapur, kulit buah, dan dedaunan memiliki proporsi yang besar, namun sebagian besar masih dibuang secara langsung sehingga menyebabkan peningkatan volume sampah di tempat pembuangan akhir serta berpotensi menimbulkan pencemaran lingkungan. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan, keterampilan, dan partisipasi masyarakat dalam pengelolaan sampah rumah tangga melalui penerapan teknologi tepat guna berupa komposter sederhana. Kegiatan dilaksanakan dengan pendekatan pemberdayaan masyarakat secara partisipatif melalui beberapa tahapan, yaitu identifikasi permasalahan mitra, sosialisasi pengelolaan sampah berbasis konsep 3R (Reduce, Reuse, Recycle), pelatihan pembuatan komposter, praktik pengolahan sampah organik menjadi kompos, serta pendampingan dan evaluasi keberlanjutan program. Hasil kegiatan menunjukkan adanya peningkatan pemahaman masyarakat mengenai pentingnya pemilahan sampah organik dan anorganik serta meningkatnya kemampuan masyarakat dalam melakukan pengolahan sampah organik menggunakan komposter. Masyarakat mampu memahami prinsip kerja komposter, melakukan proses pengisian bahan organik, melakukan pemeliharaan selama proses dekomposisi, serta memanfaatkan kompos yang dihasilkan untuk tanaman. Penerapan teknologi komposter sederhana memberikan alternatif solusi pengurangan sampah rumah tangga sekaligus mendukung terciptanya perilaku masyarakat yang lebih peduli terhadap lingkungan. Kegiatan ini menunjukkan bahwa pendekatan edukasi, pelatihan, dan pendampingan berbasis masyarakat mampu meningkatkan kapasitas masyarakat dalam mengelola sampah secara mandiri dan berkelanjutan.

Abstract

Centrifugal pumps are widely used to transport water, oil, and other fluids in industrial and utility systems, making pump performance an important consideration in system design and maintenance. This experimental study evaluates the performance characteristics of a single centrifugal pump under two unidirectional piping configurations, namely three elbows and five elbows. Testing was conducted in the Mechanical Engineering Laboratory of Universitas Islam Kalimantan MAB using a 1-inch PVC pipe installation equipped with a flow meter, pressure gauge, ammeter, and voltmeter. The analysis covered flow velocity, discharge, static head, friction head loss, elbow head loss, total head, and electrical power. The three-elbow system produced a discharge of 530 L/h, pressure of 0.14 MPa, current of 22 A, voltage of 230 V, and power of 50.6 W. The five-elbow system produced 420 L/h, 0.10 MPa, 27 A, 260 V, and 70.2 W. The results indicate that additional elbows increase hydraulic losses, reduce discharge and pressure, and increase electrical power requirements, supporting simpler piping layouts for more efficient pump operation. These findings provide practical guidance for minimizing unnecessary bends in centrifugal pump installations.

Abstract

Corrosion is a major problem affecting the durability of steel materials, creating a need for effective and environmentally friendly corrosion-control methods. This study evaluated the effectiveness of pineapple peel extract as a corrosion inhibitor for ST 42 steel in rainwater at immersion durations of 7 and 20 days. The gravimetric weight-loss method was used to determine the corrosion rate based on the mass loss of the steel specimens. Six ST 42 steel specimens were used individually for the experimental conditions, with one specimen representing each condition. Uninhibited specimens were immersed in rainwater and seawater for comparison, while pineapple peel extract was evaluated as an inhibitor only in rainwater. The uninhibited ST 42 specimens immersed in rainwater showed corrosion rates of 0.0952 and 0.1000 g/(cm²·day) after 7 and 20 days, respectively. In contrast, the specimens treated with pineapple peel extract showed no measurable mass loss, resulting in a calculated corrosion rate of 0.0000 g/(cm²·day) at both immersion durations. The calculated inhibition efficiency of the pineapple peel extract was therefore 100% at both 7 and 20 days. The uninhibited specimens in seawater showed corrosion rates of 0.0952 and 0.1000 g/(cm²·day) after 7 and 20 days, respectively, which were identical to those observed in rainwater. These results indicate the potential of pineapple peel extract as a plant-based corrosion inhibitor for ST 42 steel in rainwater under the tested conditions. However, the results should be interpreted cautiously because each condition was represented by a single specimen and the resolution of the digital scale was not documented.
