Abstract

One of the efforts to manage the risk of ground movement is to identify landslide-prone area characteristics. This study aimed to investigate the geophysical, geotechnical, and vegetation characteristics of landslide and non-landslide areas. This study adopted the resistivity geoelectric method to identify the type and structure of subsurface materials in landslide and non-landslide regions in Pujon and Ngantang, Malang Regency. Measurements in this study were done in four locations. Each geoelectric measurement path at each location was determined to be 100 m long. The electrodes were spaced apart by 10 m for measurements between the current electrode and the potential electrode. The dipole-dipole configuration of the geoelectric survey trajectory is determined based on the former landslide event to predict underground material. In addition, an investigation of geological, geotechnical, and vegetation characteristics was carried out. The results showed that the geophysical, soil, and vegetation characteristics of the landslide and non-landslide slopes were similar. The geophysical characteristics of the soil in all study locations indicate the presence of a slipping surface, which makes the land prone to landslides. The slipping plane was formed due to differences in the types of rocks between the surface and deep layers. The existence of vegetation has an important role in landslide management. Non-landslide areas tended to have denser tree vegetation and a higher number of shrub species.

Abstract

Indonesia is a maritime nation with a potential economy in the fishing sector. However, the sustainability of Indonesia's fishing sector is facing many challenges, such as overfishing, illegal fishing activities, and the degradation of marine habitats. The fishing ports play a significant role in overcoming these challenges. Therefore, the government has developed several regulations to ensure the fisheries ports provide a safe and efficient way for fishing activities, an economic center for many coastal communities, and sustainable fishing operations. There is a need to assess the effectiveness of these regulations; hence, this research aims to analyze the effectiveness of regulation in improving the services in the fishing ports. The method of stratified random sampling in proportion was conducted to select 291 participants of administrative offices, fishing companies, and fisherman organizations from 6 fishing ports in east Java Province. This research used structural equation modeling (SEM) as a comprehensive approach to assessing the effectiveness of regulation in fishing ports. The result found that the regulation variable has a significant relationship with port services that = 5.099 (p<0,001). The analysis showed that the regulation variable indirectly affects the port services variable through infrastructure, economy, and social community variables (p<0,001). Furthermore, the result recommended that the regulation will enhance port services by improving the physical infrastructure of the port, boosting the local economy, and benefiting the social community. These findings have significant implications for the fishing industry, as they demonstrate the potential for regulations to improve the efficiency and sustainability of fishing port services.

Abstract

Slope collapse can be caused by changes in load or geological conditions of the soil. Slope collapse events often occur during the rainy season in the Ponorogo area, Pacitan East Java, Indonesia, which causes closed transportation to and out of the Ponorogo area. This study aims to investigate the failure mechanism and landslide mitigation. The field investigations were conducted using geoelectricity and soil sampling to be analyzed in the laboratory. This research employed the Schlumberger geoelectrical configuration method to determine the subsurface rock lithology arrangement. The study involved acquiring data on four geoelectrical lines with a length of 135 meters. The collected field data was then processed and modeled to obtain an overview of the subsurface rock lithology arrangement. The Laboratory tests were conducted to determine the soil type and the soil parameters unit weight (?), cohesion (c'), and shear angle (?'). The laboratory data was input into software to obtain the safety factor. The geo-electrical results showed layers of clay and tuff, which identified a water flow between them, the landslide plane. Based on the finite element analysis, the landslide planes were almost coincident. Slope stability is achieved by changing the geometry and reinforcing it with piles.

Abstract

Kecamatan Sine merupakan salah satu wilayah yang memiliki potensi wisata tertinggi dengan wilayah wisata terluas yaitu 478,2 Ha dan jumlah rata – rata wisatawan sebesar 116,226 dari total 600,074 pada tahun 2018 – 2023. Dilihat dari wilayahnya, Kecamatan Sine berada di ujung barat Kabupaten Ngawi dan berbatasan dengan Kabupaten Sragen, Jawa Tengah. Hal ini menyebabkan lalu lintas didominasi oleh beberapa kendaraan berat terutama truk tangki pengangkut air yang berpotensi menyebabkan lapisan permukaan jalan mengalami penurunan tingkat kemampuan layan jalan. Oleh karena itu, diperlukan penelitian untuk mengidentifikasi penentuan skala prioritas perbaikan jalan pada wilayah dengan penggunaan lahan yang sebagian besar merupakan perkebunan yang di sekitarnya terdapat berbagai sumber mata air. Penelitian ini menggunakan metode Surface Distress Index (SDI) yang digunakan untuk menilai kerusakan fisik jalan secara visual berdasarkan luas dan lebar retakan, jumlah lubang, dan kedalaman bekas roda dengan hasil akhir berupa klasifikasi kondisi jalan menjadi baik, sedang, rusak ringan, dan rusak berat dan metode Analytical Hierarchy Process (AHP) untuk menentukan bobot prioritas perbaikan jalan berdasarkan tiga kriteria utama: kondisi jalan, kinerja jalan, dan tata guna lahan. Hasil penelitian ditemukan nilai kondisi jalan didapatkan bahwa yang mengalami kerusakan terbesar adalah Jalan Raya Sine dengan nilai SDI sebesar 50,96 (Baik). Untuk penentuan kriteria perbaikan jalan di Kecamatan Sine, Kabupaten Ngawi dengan metode AHP diperoleh kriteria tata guna lahan sebagai kriteria tertinggi dengan bobot 0,146. Secara keseluruan, dari penilaian masing – masing kriteria terhadap 3 ruas alternatif jalan didapatkan bahwa ruas Jalan Ketanggung – Mantin ditetapkan sebagai prioritas utama untuk diperbaiki dengan bobot nilai 0,224. Kata kunci: SDI, AHP, Kondisi Perkerasan Jalan, Urutan Prioritas Perbaikan Jalan
