Abstract

Sistem irigasi di Indonesia memiliki peranan penting dalam mendukung kedaulatan ketahanan pangan pertanian, namun dari hasil pengamatan dan data IKSI yang ada menyatakan fungsi sistem jaringan Daerah Irigasi Cipanas II di Kabupaten Indramayu mengalami penurunan kinerja yang berdampak pada produktivitas tanam. Pemerintah berupaya mengoptimalkan kembali pengelolaan sistem irigasi Daerah Irigasi Cipanas II agar lebih efektif dan efisien dalam pemberian layanan air irigasi. Pemeliharaan infrastruktur prasarana fisik irigasi dan partisipasi Perkumpulan Petani Pengguna Air (P3A) sangat penting untuk diperhatikan. Penelitian berfokus pada infrastruktur prasarana fisik irigasi dan keberhasilan P3A, dengan tujuan untuk mengidentifikasi pengaruh terhadap hasil produktivitas tanam pertanian pada kondisi kinerja jaringan Daerah Irigasi Cipanas II. Metode yang digunakan dalam penelitian ini adalah kuantitatif deskriptif. Data primer dan sekunder didapat melalui hasil pengamatan, identifikasi, evaluasi dan analisis data untuk menilai hubungan antara indikator kinerja prasaranan fisik dan kelembagaan P3A terhadap produktivitas tanam dari data penilaian Indeks Kinerja Sistem Irigasi (IKSI) dari tahun 2019 hingga 2024, dianalisis dengan metode regresi Uji F dan Uji T. Dari hasil analisis data penelitian diperoleh bahwa Kinerja Prasarana Fisik pada tahun 2019 - 2024 mengalami peningkatan sebesar 15,71 %, Perkumpulan Petani Pengguna Air (P3A) mencapai 1,79 % dan penilaian kinerja Produktivitas Tanam mencapai 6,72 %. Berdasarkan Uji F, terungkap bahwa komponen Prasarana Fisik dan Perkumpulan Petani Pengguna Air (P3A) secara simultan tidak berpengaruh terhadap Produktivitas Tanam. Sedangkan berdasarkan Uji t disimpulkan Komponen Prasarana Fisik dan Perkumpulan Petani Pengguna Air (P3A) secara parsial memberikan pengaruh signifikan terhadap Produktivitas Tanam. Hasil evaluasi dan perencanaan yang sistematis untuk kegiatan operasional, pemeliharaan dan rehabilitasi sistem irigasi sangat penting untuk mengoptimalkan kinerja sistem irigasi di wilayah daerah irigasi tersebut.

Abstract

This research discusses efforts to revitalize the Batujai Reservoir in Central Lombok with a focus on sedimentation problems. Batujai Reservoir has a strategic role in meeting water needs in the surrounding area, but faces serious challenges due to significant sedimentation. In addition to assessing the effects of these changes on the reservoir's benefits—such as irrigation, flood control, and electricity production—this study intends to examine the effects of land use changes in the Dodokan Sub-Watershed Catchment Area (DTA) on the features and volume of sedimentation entering the reservoir. In addition, this study attempts to develop suggestions for efficient sedimentation management plans in order to increase the Batujai Reservoir's service life. Research methods include primary and secondary data collection, sedimentation modeling using the Water and Tillage/Sediment Delivery Model (WATEM/SEDEM), to evaluate the impact of sediment control structures such as check dams. Research variables include catchment area, population, annual rainfall, average daily evaporation, mainstay surface water availability, land surface erosion rate, sediment volume deposited in the reservoir, effective age of the Batujai Reservoir, and changes in land use in the Dodokan Sub-watershed. The results of this research will provide a better understanding of the main sources of sedimentation in the Batujai Reservoir and the impact of land use changes on the reservoir. It is hoped that the recommendations for sedimentation management strategies resulting from this research will help maintain reservoir storage capacity, which is important for meeting various water needs in the region.

Abstract

Pilot ladder operations are a critical component of pilotage services and inherently involve high safety risks. Although international standards such as SOLAS and ISO 799-1 provide strict guidelines, accidents continue to occur due to technical limitations, human factors, and managerial deficiencies. This study assesses the pilot ladder safety systems on Cruise Ship MV Westerdam and Cargo Ship MV Hao Qiang 57 at Tanjung Perak Port. A descriptive qualitative approach was employed using a safety checklist, short interviews, and limited observations, focusing on six aspects: ladder condition, safety fittings, lighting, cleanliness, usage, and maintenance. The results show that MV Westerdam achieved full compliance (100%) with all safety standards, supported by complete maintenance records and regular crew training. In contrast, the MV Hao Qiang 57 demonstrated only 70% compliance, with key deficiencies in the availability of safety harnesses, updated crew training, and maintenance documentation. These findings indicate that pilot ladder safety cannot be ensured solely through the physical conditions of the ladder but requires an integrated approach encompassing technical, human, and managerial dimensions. MV Westerdam illustrates best practices in implementing safety systems, while MV Hao Qiang 57 highlights critical areas for improvement. Overall, this study provides both theoretical contributions to maritime safety literature and practical recommendations for enhancing safety systems in Indonesian ports.
