Abstract

A check dam is a construction solution to overcome various catchment area challenges, especially erosion and sedimentation control in the upstream region. The strategic implementation of this plan includes various methodologies such as topographic, geotechnical identification, hydrological analysis, sedimentation analysis, material specification, hydraulic analysis, stability analysis, storage capacity analysis, and budget plan development. The purpose of this research is to check dam planning using waste tires which includes sediment discharge, detailed dimensions of the building, and building safety, to the required cost budget plan by reviewing the aspects of environmentally friendly, low cost, and waste utilization by sustainable development goals. The type of sediment flow that occurs is debris flow with a sediment discharge rate of 25,939 m3/s, due to the flood discharge phenomenon with a significant 25-year return period is 10,580 m3/s. The safety number of the proposed check dam design using the calculation of forces acting and Plaxis 2D V20 software has exceeded the safety permit requirements with various conditions that may occur at the study site. In a single flood, this check dam can effectively mitigate for approximately 4 days. To implement this development plan, an estimated budget of IDR773.472.940 has been projected.

Abstract

Erosi merupakan masalah lingkungan yang disebabkan adanya faktor alih fungsi lahan, kemiringan lereng, karakteristik tanah serta aktivitas manusia yang juga menyebabkan merosotnya produktivitas tanah. Beberapa peristiwa erosi terjadi di Kota Batu terutama di kawasan Sumber Brantas yang mengakibatkan kerugian. Dengan melihat hal itu, diperlukan solusi terbaru untuk mengurangi sedimen dengan mempertimbangkan aspek sustainable and recycle yaitu dengan perencanaan bangunan penahan sedimen gully plug dengan menggunakan bahan utama struktur dari ban yang diisi oleh mortar beton sebagai pemberat. Dari hasil perencanaan gully plug didapatkan hasil tinggi total sebesar 5,6 m, serta lebar dasar gully plug sebesar 6,5 m, dengan jumlah ban yang dibutuhkan sebanyak 690 ban. Dimensi gully plug disesuaikan dengan debit banjir rancangan, laju erosi, dan jenis material sedimen di lokasi studi. Dari perencanaan gully plug ini diharapkan dapat mengurangi sedimen di hilir serta dapat mengurangi tingkat kemiringan lereng di lokasi studi.

Abstract

Limited irrigation water availability constrains irrigation management and reduces agricultural profitability. This study aims to maximize agricultural profit by optimizing irrigation water distribution using a deterministic dynamic programming model in the Ameroro Irrigation Area, Konawe Regency, Indonesia. The model was structured with planting seasons as stages, irrigation water availability as the state variable, and water allocation as the decision variable. The objective function maximized total profit based on cultivated land area under a rice–rice–secondary crops cropping pattern across a total irrigated area of 2,100 ha. Model constraints included dependable discharge, seasonal water availability, crop water requirements, and land area limitations. In the existing condition, agricultural profit reached IDR 37.4 billion in planting season I, IDR 37.4 billion in planting season II, and IDR 8.6 billion in planting season III, totaling IDR 83.4 billion annually. After optimization, profits increased to IDR 42.03 billion, IDR 44.07 billion, and IDR 12.90 billion, respectively, resulting in a total annual profit of IDR 99.00 billion. The results indicate that deterministic dynamic programming improves water allocation efficiency and increases agricultural profit without additional water resources, supporting sustainable irrigation management.

Abstract

Perubahan tata guna lahan di wilayah perkotaan mengakibatkan berkurangnya kawasan resapan air, yang berkontribusi pada peningkatan risiko genangan banjir. Hal ini khususnya terjadi di Kota Malang, terutama di kawasan Dinoyo, yang sering mengalami genangan air akibat terbatasnya ruang terbuka hijau dan drainase yang tidak memadai. Program Pengabdian Kepada Masyarakat (PKM) ini bertujuan untuk mengedukasi masyarakat dan pelajar mengenai pentingnya sumur resapan dalam mitigasi genangan banjir dan konservasi air. Kegiatan ini juga melibatkan pembangunan sumur resapan di RW 05 Kelurahan Dinoyo. Metode yang digunakan adalah pendekatan kaji tindak (action research) dengan tahapan edukasi, sosialisasi, survei lapangan, pembangunan, dan pemeliharaan sumur resapan. Hasil pelaksanaan menunjukkan bahwa pembuatan sumur resapan dapat mengurangi genangan air di kawasan tersebut, meningkatkan kualitas pengelolaan air tanah, serta memberikan pemahaman kepada masyarakat mengenai pentingnya pengelolaan air hujan. Program ini diharapkan menjadi model bagi wilayah lain dalam mengatasi permasalahan serupa. Keberlanjutan proyek ini memerlukan pemeliharaan rutin dan perluasan pembuatan sumur resapan di daerah rawan genangan lainnya.

Abstract

The Melawi Dry Dam is a zoned embankment dam with clay core located in West Kalimantan, Indonesia. As a flood-control structure, it undergoes significant wet–dry cycles that modify stress distribution and pore water pressure, potentially influencing plastic deformation within the core zone. This study aims to evaluate the effects of clay core thickness and permeability coefficient on vertical plastic deformation using a combination of fully coupled flow–deformation and plastic analysis in PLAXIS 2D. Numerical simulations represent a post-flood condition followed by a 130-day consecutive dry season period, defined as Julian days when rainfall remains at the lower rainfall-gradient threshold, during which the reservoir remains empty because inflow exceeds outlet capacity. Nine scenarios were analyzed by combining three core thicknesses (11.64, 19.40, and 27.16 m) with three laboratory-determined permeability coefficients. The results indicate that seven scenarios remain below the maximum allowable deformation limit of 1.0% of the dam height. Statistical analysis shows a strong correlation between core thickness, permeability, and deformation (R = 0.929). Multiple linear regression (Significance F = 0.00253; p < 0.05) confirms that both variables significantly affect deformation. Increasing core thickness consistently reduces plastic deformation, while lower permeability enhances resistance to seepage-induced instability, thereby supporting safe dry dam design.

Abstract

Water is fundamental to cooking, bathing and hygiene, and essentially for life itself. Across many areas, communities rely on bore well water as a source of raw water for domestic needs. Yet this resulting water is mostly not of an appropriate quality, as it has a high iron content and hardness. This study evaluates the performance of a combined vertical-flow and horizontal flow roughing filter (VRF and HRF) system for bore well water treatment. The system was tested using various alternative filter media, including coconut fiber, silica sand, activated carbon, zeolite, pumice stone, and volcanic black sand, arranged in different configurations. The vertical-flow unit used a media depth of 6 cm, while the horizontal-flow unit used a depth of 15 cm. The results showed that all configurations effectively improved water quality and met standard requirements. The highest performing model, consisting of volcanic black sand, activated carbon, zeolite, and silica sand, achieved a 97.5% reduction in iron and a 13.2% reduction in hardness. These findings indicate that optimized roughing filter systems offer a low cost and efficient solution for decentralized water treatment.

Abstract

Desa Ngebel di lereng Gunung Wilis memiliki potensi kopi Robusta yang besar, namun terkendala oleh tingginya kelembapan udara dan anomali cuaca yang menyebabkan proses pengeringan konvensional memakan waktu hingga 14 hari dengan kadar air yang tidak stabil, sehingga menurunkan kualitas citarasa biji kopi. Pengabdian ini hadir sebagai solusi melalui intervensi teknologi yang terbukti mampu mereduksi waktu pengeringan secara signifikan menjadi hanya 3–4 hari sekaligus menjaga konsistensi kadar air akhir pada standar optimal 12%. Pengabdian ini bertujuan untuk mengimplementasikan teknologi tepat guna berupa alat pengering kopi Smart Dryer Box berbasis mikrokontroler Arduino Uno sebagai solusi standarisasi proses pascapanen kopi. Metode pelaksanaan menggunakan pendekatan Participatory Rural Appraisal (PRA) yang diterapkan secara nyata mulai dari tahap identifikasi kebutuhan bersama dan pemetaan kendala mikroklimat bersama pengurus BUMDesa, pengambilan keputusan partisipatif terkait spesifikasi desain kapasitas Smart Dryer Box, hingga proses instalasi perangkat serta pelatihan teknis operasional bagi operator di BUMDesa Barokah. Hasil kegiatan menunjukkan bahwa Smart Dryer Box mampu menstabilkan suhu ruang pengering pada rentang 45°C hingga 50°C secara otomatis, yang secara signifikan mereduksi durasi pengeringan dari sekitar 2 minggu menjadi hanya 3-4 hari tanpa tergantung cuaca. Analisis data terhadap performa alat membuktikan bahwa perangkat ini dirancang efektif untuk mengejar target kadar air biji kopi pada standar 12% secara konsisten melalui simulasi durasi pengeringan yang terukur tanpa tergantung pada sinar matahari. Selain itu, berdasarkan evaluasi performa kerja melalui indikator praktik, mitra menunjukkan tingkat pemahaman sebesar 85% yang diukur dari keberhasilan pengoperasian mandiri sistem otomasi serta ketepatan dalam melakukan prosedur perawatan alat. Kesimpulannya, hilirisasi teknologi otomatisasi ini berhasil meningkatkan efisiensi produksi dan menjamin mutu kopi Robusta Wilis yang berkelanjutan. Program ini memberikan dampak nyata pada penguatan daya saing ekonomi desa melalui modernisasi infrastruktur pertanian berbasis digital.
