Abstract

Kepemimpinan merupakan salah satu faktor yang sangat penting dalam pembangunan kampung, karena baik buruknya pembangunan kampung tergantung dari pemimpinnya. Rumusan masalah dari penelitian ini adalah untuk melihat “Bagaimana peran kepemimpinan ondofolo dalam pembangunan kampung di kampung Ifale Distrik Sentani Kabupaten Jayapura”. Tujuan penelitian ini adalah untuk mengetahui peran kepemimpinan ondofolo dalam pembangunan kampung. Jenis penelitian ini adalah penelitian deskriptif dengan teknik analisis deskriptif kuantitatif. Populasi dalam penelitian ini jumlahnya 20 orang. Sampel dalam penelitian ini jumlahnya sedikit maka tidak ditarik sampel. Teknik pengumpulan data yang digunakan dalam penelitian ini ada dua yaitu, penelitian perpustakaan dan penelitian lapangan berupa pengamatan, wawancara, dan kuesioner. Adapun teknik analisis data yang digunakan adalah teknik analisis data kuantitatif. Hasil penelitian di masyarakat menunjukkan bahwa ondofolo belum mampu berperan untuk memimpin masyarakat sehingga pembangunan tidak berjalan dengan baik. Dengan demikian peran kepemimpinan ondofolo dalam pembangunan kampung di kampung Ifale harus ditingkatkan agar masyarakat dapat hidup sejahtera.

Abstract

The sago plant (Metroxylon sago) is native to Southeast Asia and thrives in swampy areas and riverbanks in Indonesia, with centers of distribution in Papua, Maluku, Sulawesi and Riau. In Papua, sago plays an important role in the social, economic and ecological aspects of the local community, as well as being a staple food consumed for generations. However, rapid development in Jayapura Regency, especially in Nendali Village, threatens the sustainability of the sago forest. This research uses a descriptive method to evaluate the existing condition of sago forest shrinkage through observation, interviews, and documentation. The results showed that development activities have caused the sago forest area to shrink by 114,629.76 m² between 2015 and 2020. Sago forests were converted into built-up land and open land, which amounted to 5,864.59 m² and 5,284.53 m² respectively. The SWOT analysis revealed that despite internal weaknesses, opportunities for sago forest protection exist through existing regulations. Thus, it is expected that the Jayapura District Regulation can be a reference in sustainable development and protection of sago forests for the welfare of local communities.

Abstract

Single Lane Free Flow (SLFF), known as “Let It Flo,” is a contactless toll payment system based on RFID technology developed by PT Jasamarga to reduce transaction time and queuing at toll gates. However, its implementation has not been fully effective due to low user adoption. This study aims to identify the implementation of SLFF, analyze vehicle flow, service time, service level, and delay time between the E-Toll and SLFF systems, as well as evaluate user perceptions toward the system. The analysis applies queuing theory using vehicle survey data collected at the Bekasi Timur 2 Toll Gate on January 13, 16, and 18, 2025, and questionnaires distributed to toll road users. The results show that SLFF is only used by four-wheeled light vehicles with a low adoption rate of two vehicles per hour compared to 343 vehicles per hour for E-Toll. Nevertheless, SLFF can reduce delay time by 0.6 seconds per vehicle and increase service capacity with a projected result of 6,000 vehicles per hour, significantly higher than the E-Toll system’s capacity of 957 vehicles per hour. The system eliminates queues and reduces congestion with a service intensity below one (ρ < 1), while users report improved safety and comfort due to non-stop and contactless transactions. The main challenges include limited infrastructure, restricted gate availability, ongoing application development, and limited technological information on the SLFF/Flo system. Therefore, infrastructure expansion, application improvement, and government support are essential to accelerate adoption and enhance the performance of the toll system in Indonesia.

Abstract

Groundwater is dynamic and influenced by natural factors, such as geology and geomorphology, which affect aquifer characteristics, groundwater movement, and surface morphology. This study aims to identify subsurface aquifer positions and the distribution of groundwater depth in Oksibil District, Pegunungan Bintang Regency. The research utilizes the resistivity geoelectric method with a Wenner configuration to determine lithology and aquifer characteristics. Measurements were conducted using the AIDU Golden Rod instrument, which analyzes natural electric fields. Results indicate the presence of pressurized aquifers at depths ranging from 125 to 300 meters with varying thicknesses of 20 to 85 meters. In contrast, free aquifers are primarily located at shallow depths (0–40 meters) in specific areas, such as Kabiding. The findings provide valuable insights into groundwater resource management and regional aquifer potential in Pegunungan Bintang Regency
