Abstract

ABSTRAK Kecepatan aliran air di sekitar pilar jembatan memiliki peran penting dalam menyebabkan gerusan lokal (local scouring), yang berpotensi merusak stabilitas struktur. Studi ini bertujuan untuk menguji efektivitas deflektor bawah air berbentuk silinder pori bertulang dalam menurunkan kecepatan aliran, sehingga dapat mengurangi risiko gerusan pada fondasi jembatan. Penelitian dilakukan melalui pendekatan eksperimental di Laboratorium Hidraulika Universitas Muhammadiyah Makassar, menggunakan saluran terbuka dengan kondisi yang menyerupai aliran sungai alami. Dua skenario debit digunakan, yaitu Q1 dan Q2, dengan pengamatan kecepatan aliran dilakukan pada interval waktu 5, 10, dan 15 menit. Data diambil pada 15 titik pengamatan di sepanjang saluran, baik sebelum maupun sesudah pemasangan deflektor. Hasil menunjukkan bahwa deflektor mampu menurunkan kecepatan aliran secara signifikan. Pada debit Q1, kecepatan menurun dari rata-rata 0,618 m/dtk menjadi 0,39 m/dtk. Sementara pada Q2, terjadi penurunan dari 0,707 m/dtk menjadi 0,437 m/dtk. Selain itu, pola aliran berubah menjadi lebih stabil dan terkontrol, dengan berkurangnya formasi vorteks yang biasanya menyebabkan erosi. Temuan ini menunjukkan bahwa deflektor silinder pori bertulang efektif sebagai strategi mitigasi gerusan yang adaptif dan efisien. Penggunaan struktur ini diharapkan dapat diterapkan secara luas dalam perencanaan dan perlindungan infrastruktur jembatan di lingkungan sungai berkecepatan tinggi. ABSTRACT The velocity of water flow around bridge piers plays a critical role in causing local scour, which threatens structural stability. This study aims to examine the effectiveness of reinforced porous cylindrical underwater deflectors in reducing flow velocity and mitigating scour risk. An experimental approach was conducted at the Hydraulics Laboratory of Universitas Muhammadiyah Makassar using an open channel flume simulating natural river conditions. Two discharge scenarios (Q1 and Q2) were tested, with flow velocities observed at intervals of 5, 10, and 15 minutes. Data collection was carried out at 15 observation points along the channel, both before and after the installation of the deflector. The results show a significant reduction in flow velocity following the use of the deflector. Under Q1, the average velocity decreased from 0.618 m/s to 0.39 m/s, while under Q2, it dropped from 0.707 m/s to 0.437 m/s. Furthermore, the deflector contributed to more stable and controlled flow patterns, reducing vortex formation commonly associated with erosion. These findings demonstrate that reinforced porous cylinder deflectors are an effective, adaptive, and efficient strategy for local scour mitigation. The implementation of such structures offers promising potential in the planning and protection of bridge infrastructure located in high-velocity river environments.

Abstract

Background: Access to electricity in rural areas of Indonesia remains limited, leading to socio-economic challenges such as low productivity, limited education opportunities, and inadequate healthcare services. Micro-hydro power plants (MHPP) have emerged as a promising solution to support rural electrification, offering renewable, decentralized energy sources suitable for remote communities. Objective: This study aims to review the development and application of micro-hydro power plant technology in Indonesia, analyzing its technical characteristics and evaluating its socio-economic impacts on rural communities. Methodology: A systematic literature review was conducted, encompassing peer-reviewed articles, government reports, and case studies from various rural regions in Indonesia. The analysis focused on technical specifications, implementation strategies, community involvement, and socio-economic outcomes associated with micro-hydro projects. Results: Findings indicate that MHPP technology in Indonesia has demonstrated reliable energy generation with capacities ranging from 5 kW to 100 kW, suitable for small communities. Socio-economic benefits include increased household income, improved educational access, enhanced local business development, and strengthened community cohesion. However, challenges such as high initial investment, technical maintenance requirements, and limited technical expertise in rural areas have constrained widespread adoption. Community participation and government support were identified as critical factors for project sustainability. Conclusion: Micro-hydro power plants present an effective approach to rural electrification in Indonesia, with significant socio-economic benefits when supported by local engagement and institutional frameworks. Future policies should focus on reducing technical and financial barriers to maximize the positive impact of MHPP on rural development.

Abstract

The Jeneberang River plays a vital role in flood control for Makassar City and Gowa Regency. However, it faces severe sedimentation problems following the landslide at Mount Bawakaraeng, which released approximately 200 million m³ of mud and sand into downstream areas. Sedimentation at the estuary reduces the river’s discharge capacity to the sea and significantly disrupts fishing vessel accessibility in the Tanjung Bunga area. This study aims to analyze coastal morphological dynamics and evaluate the effectiveness of jetty construction in controlling sediment accumulation using numerical simulations with Delft3D. The data employed include bathymetry, tides, currents, and sediment characteristics obtained from BMKG and Ina-Geoportal. Simulation results indicate substantial sediment buildup at the estuary prior to jetty construction. After the jetty was introduced, sediment concentration at the river mouth decreased markedly from 1.4 kg/m³ to 0.16 kg/m³ by the end of the simulation period. Morphologically, the jetty reduces current energy and alters sediment transport pathways, thereby maintaining the stability of the navigation channel. The novelty of this study lies in its quantitative evaluation of jetty effectiveness under extreme sediment supply conditions caused by large-scale upstream landslides, providing numerical-based evidence for jetty performance in highly sediment-laden estuaries. These findings confirm that jetty construction is an effective engineering solution to sustain navigation channels and support the continuity of local fishing activities.

Abstract

Pemecah gelombang berpori merupakan struktur yang dirancang untuk melindungi garis pantai dari erosi dan abrasi yang disebabkan oleh energi gelombang. Penelitian ini bertujuan untuk menganalisis pengaruh diameter lubang terhadap koefisien refleksi dan transmisi pada pemecah gelombang sisi miring berpori. Dalam penelitian ini, model pemecah gelombang dengan variasi diameter lubang dan jarak antar lubang digunakan untuk mengukur koefisien refleksi dan transmisi. Hasil penelitian menunjukkan bahwa diameter lubang berpengaruh signifikan terhadap koefisien refleksi dan transmisi. Model dengan diameter lubang yang besar menunjukkan nilai koefisien refleksi yang lebih kecil dan nilai koefisien transmisi yang lebih besar. Hal ini karena gelombang yang menerpa model dengan diameter lubang yang besar cenderung lebih diserap dan tidak dipantulkan secara signifikan, sehingga energi gelombang yang datang dapat lebih efektif diredam.
