Abstract

Salah satu permasalahan pada operasional sebuah waduk adalah sedimentasi. Kapasitas tampungan waduk dipengaruhi oleh volume sedimen yang masuk ke waduk. Akibat sedimentasi dapat berpengaruh terhadap umur waduk. Untuk menanggulangi permasalahan sedimentasi pada waduk perlu diketahui perkiraan volume sedimen yang masuk ke waduk. Analisis jumlah sedimen yang masuk ke Waduk Jatibarang dilakukan dengan menjumlahkan total sedimen layang dan sedimen dasar. Simulasi dilakukan selama umur rencana waduk yaitu 50 tahun. Sedimen layang dihitung dengan menurunkan persamaan dari data pengukuran debit air dan konsentrasi sedimen. Sedimen dasar dianalisis melalui pendekatan rumus empirik dari Meyer-Petter Muller. Adapun total perkiraan sedimen yang masuk ke waduk selama 50 tahun adalah sebesar 7.629.799,05 m3. Selanjutnya perhitungan sedimen yang mengendap dilakukan dengan metode trap efficiency oleh Brune dan menghasilkan nilai sebesar 6.643.514,71 m3. Dari perhitungan diketahui volume akhir waduk pada tahun ke-50 adalah 13.756.485,29 m3. Sedimen yang mengendap di waduk diperkirakan sebesar 132.870,29 m3 per tahun. Dengan menggunakan data volume dead storage berdasar data teknis waduk 6.800.000 m3, dihitung sisa volume yang ada yaitu sebesar 156.485,29 m3. Perhitungan sisa umur waduk diperoleh dengan membandingkan sisa volume dengan volume sedimen per tahun. Berdasarkan hasil analisa, dapat disimpulkan bahwa rencana umur Waduk Jatibarang adalah 51,1 tahun. Kata Kunci: sedimentasi, sedimen layang, sedimen dasar, trap efisiensi, Waduk Jatibarang

Abstract

The East Semarang watershed is an area with diverse land conditions and the majority of the upstream and downstream areas are converted into settlements. This results in an increase in the rate of erosion which erodes the land and causes sedimentation in the downstream watershed. The higher the erosion rate, the higher the sedimentation, therefore the prediction of the erosion value is important as an indicator to recommend natural resource conservation activities. The purpose of this study is to predict erosion and sedimentation rates, and to recommend good conservation methods in an effort to reduce soil erosion. Land erosion analysis was obtained from the overlay of erosion parameter layers with the help of the ArcGIS program using the USLE (Universal Soil Loss Equation) method. Not all of the eroded soil surface in the watershed will be transported to the river, but some will settle on the watershed surface due to the interaction between the flow and the watershed surface. Sediments carried by measured river flows at the outlet were analyzed using the SDR (Sediment Delivery Ratio) method. Then it can be known the amount of sediment per year in the East Semarang watershed or by the term SY (Sediment Yield). Based on the calculation of land erosion in the East Semarang watershed, as big as 816,910.81 tons/year, which resulted in a total sedimentation of 4,641.39 tons/year. Erosion hazard classifications vary from very light to very severe, with the majority of the class being very severe in the upstream region with an area of ​​7,003.55 Ha. The recommendation proposed to overcome or reduce erosion is technical conservation, namely terracing and check dam techniques.

Abstract

The Sringin is a downstream river located in East Semarang. The Sringin River becomes the channel waste of the East Semarang district area. The Sringin River bank is surrounded by the Terboyo industrial area and settlement. The flood occurred in both areas, especially at Ngilir village, Genuk subdistrict. It is caused by low-capacity sedimentation channels and buildings occupying the channel body. The study aims to estimate flood discharge during repeat period 2, 5, 10, 25, 50, and 100 years on Sringin river downstream, analyze the capacity cross-section river, and identify the river water level profile when debit flowed with various period repeat flood. The hydrology calculation showed that flood discharge plans in the repeat period 2, 5, 10, 25, 50, and 100 years are 12.42; 16.67; 19.81; 30.7; 31.6; 33.22 m 3 /s. At the same time, the flow river capacity is 2.95 m/s in the upstream section and 15.52 m/s in the downstream section. Thus, floods occurred in some places when large discharges flowed. In period 2, the water level is about 1.0 to 1.5 meters. In more repeat periods, the level is higher. The conclusion is that the Sringin River cannot flow with perfect discharge, which exceeds its flow capacity.

Abstract

Occupational safety, health, and environment (OSH) is inseparable from the labor and human resources system. Not only are safety, health and the work environment very important for employees, but safety, health, and the work environment also determine workplace productivity. According to Law Number 13 of 2003 concerning Employment, what is meant by employment for workers is the obligation to provide protection, including the welfare of body and soul, safety, and health of workers. Companies take various steps to protect their employees from the dangers of work accidents. Personal Protective Equipment (PPE) is an effort to protect part or all of the body from the potential hazards of work accidents and occupational diseases. This activity aims to foster a sense of responsibility among workers regarding the importance of implementing OSH so that they can minimize the number of work accidents. The method used in socialization is lectures. The results obtained are an increase in workers' understanding and discipline regarding the importance of OSH in the field.

Abstract

Sustainable Development Goals (SDGs) adalah lanjutan dari Program Millenium Development Goals (MDGs). MDGs) adalah upaya untuk meningkatkan kehidupan masyarakat termiskin di dunia melalui 8 tujuan pembangunan, sedangkan SDGs memiliki 17 tujuan pembangunan berkelanjutan dengan 169 target, cakupannya lebih luas dari MDGs. Meskipun SDGs memiliki 17 tujuan utama, fokus pada artikel ini adalah air bersih dan sanitasi layak. Tujuan dari penelitian ini adalah untuk mengidentifikasi neraca air baku di WS Jratunseluna dan upaya-upaya meningkatkan kualitas air baku guna menunjang ketercapaian Target SDG's Tahun 2030. Metode yang dipilih adalah kualitatif, dengan data utama dikumpulkan melalui survei literatur dari berbagai sumber, termasuk buku, jurnal ilmiah, artikel, dan internet. Untuk melakukan review, peneliti akan menyelidiki jurnal-jurnal tertentu secara menyeluruh dan metodis menggunakan protokol yang telah ditetapkan. Berdasarkan analisa yang telah dilakukan, dapat diambil kesimpulan bahwa dengan kebutuhan total air baku di WS Jratunseluna pada awal tahun simulasi (2023) sebesar 50,57 m3/dt ternyata masih defisit dengan suplai yang dapat dilakukan hanya sebesar 48,77 m3/dt. Setelah dilakukan upaya penambahan dan optimalisasi infrastruktur air baku, dapat diprediksikan meningkatkan suplai hingga 62,79 m3/dt pada Tahun 2033 dengan berbagai kegiatan yang dilakukan. Sehingga diklaim dapat menutup defisit air yang terjadi pada awal tahun simulasi.

Abstract

The Pakijangan River Basin in Brebes Regency plays a critical role in supplying raw water for domestic, agricultural, and environmental needs. However, the absence of continuous streamflow records and increasing pressure on water resources pose significant challenges to effective management. This study aims to quantitatively estimate water allocation within the basin through a water balance approach. The methodology includes field surveys of existing conditions, analysis of water demand and availability, and water balance simulation using the RIBASIM (River Basin Simulation) model integrated with the Sacramento rainfall-runoff method. Rainfall data were obtained from two representative manual stations: Klampok and Slatri. Simulation results indicate that the Pakijangan Basin remains in surplus throughout the year, with dependable flow sufficient to meet all domestic and non-domestic water demands. With a distribution efficiency indicator (K factor) of 1, the basin even has the capacity to supply neighboring basins (Pemali River Basin) at a rate of 0.1 m³/s. These findings serve as a valuable foundation for sustainable, equitable, and efficient water resource planning and management in the region

Abstract

Bendungan Randugunting di Kabupaten Blora dibangun sebagai infrastruktur pengendali banjir, penyedia air baku, dan irigasi. Namun, pada beberapa kejadian banjir di hilir Sungai Banyuasin, wilayah Rembang, muncul persepsi bahwa operasional Bendungan Randugunting turut berkontribusi terhadap peningkatan debit banjir di daerah hilir. Penelitian ini diharapkan dapat memberikan klarifikasi ilmiah terhadap dugaan pengaruh Bendungan Randugunting terhadap banjir di hilir Sungai Banyuasin Rembang. Penelitian ini bertujuan untuk mengevaluasi kontribusi pelepasan air bendungan terhadap debit puncak banjir di Sungai Banyuasin. Metode yang digunakan meliputi analisis hidrologi dengan pemodelan menggunakan perangkat lunak Hydrologic Engineering Center–Hydrologic Modeling System (HEC-HMS), dan analisis hidrolika dengan bantuan model Hydrologic Engineering Center–River Analysis System (HEC-RAS) 2D untuk memodelkan genangan banjir. Hasil analisis pelepasan air Bendungan Randugunting, dapat disimpulkan bahwa waduk dapat menahan banjir di hulu, meredam sehingga rilis banjir cukup kecil dg kemampuan reduksi ±70% pada simulasi kala ulang 50th (outflow 63,4 m³/dt). Namun Kali Padas dengan luas Catchment area 2 (dua) kali luas DTA (Daerah Tangkapan Air) bendungan, menghasilkan pelepasan air sebesar 146 m3/dt. Melalui justifikasi teknis, banjir di daerah hilir waduk dipengaruhi oleh pelepasan air Kali Padas. Kondisi Kali Padas yang tanpa bangunan penahan banjir, diprediksi sebagai sumber limpasan terbesar penyebab banjir di pohlandak dan krikilan.
