Abstract

The use of wind energy as one of the producers of electrical energy is done by converting mechanical energy into electrical energy from wind turbines, one of which is the savonius wind turbine. Savonius wind turbines in use are able to work at low wind speeds. This study aims to evaluate the potential of wind energy that can be generated by optimization in savonius wind turbines by measuring the power generated by varying the gap distance between Balde and turbine shafts and analyzing the most optimal power as a source of power generation on the coast of Sarmi Regency, Papua Province. The analysis method in this study is field surveys, wind speed measurements, power optimization, BHP and tool efficiency carried out with variations in the distance between the blade and turbine shaft, namely 5 cm, 10 cm and 15 cm. The results of this study stated that the most optimal and stable results on the power generated by the turbine as well as the BHP value and the best tool efficiency were a distance variation of 15 cm with an average power value produced (P0) of 15.55 Watts, an average BHP value of 0.56 Watts and an average efficiency value of 7.59%.

Abstract

This study examines the integration of indigenous knowledge systems (IKS) from Papuan communities into contemporary urban planning frameworks in Jayapura, the capital city of Papua Province, Indonesia. Rapid urbanization in Papua has created significant tensions between modern city development paradigms and the deeply rooted traditional wisdom of indigenous Papuan peoples, including the Sentani, Tobati-Enggros, and Ormu communities. Employing a qualitative research methodology with ethnographic and participatory approaches, the study explores how traditional ecological knowledge, spatial cosmologies, and community governance structures can be scientifically operationalized within urban master plans. Data were collected through in-depth interviews with community elders, urban planners, and local government officials, supplemented by field observations and document analysis. Findings reveal that Papuan indigenous knowledge offers robust frameworks for sustainable land use, water management, and social cohesion that are largely overlooked by conventional planning instruments. The study concludes that a decolonizing approach to urban planning, one that systematically incorporates indigenous epistemologies as co-equal knowledge systems, can produce more culturally responsive, ecologically sustainable, and socially just cities in Papua. Policy recommendations for institutional mechanisms to formalize this integration are provided.

Abstract

This study aims to analyze the regional economic potential in increasing Local Own-Source Revenue (PAD) in the proposed expansion of Malamoi Regency from Sorong Regency. A mixed-methods descriptive approach was employed, incorporating qualitative descriptive analysis, Location Quotient (LQ), and sectoral contribution analysis. The findings reveal that the Malamoi region has six main economic potentials: agriculture, livestock, forestry, fisheries and marine, mining, and tourism. Based on LQ analysis, the broad agricultural sector is a base sector (LQ = 1.42 > 1) with potential as the primary economic driver, while the mining and tourism sectors are classified as non-base sectors (LQ < 1). In terms of contribution, the mining sector contributes the most (15.68%), the broad agricultural sector contributes moderately (9.57%), and tourism contributes minimally (0.33%). The study concludes that the economic potential of Malamoi can support PAD growth and strengthen regional fiscal independence when managed optimally with adequate infrastructure support.

Abstract

Waste management remains a critical challenge in developing regions of Eastern Indonesia, particularly in Kalibobo Urban Village, Nabire District, Central Papua Province. This study analyzes the availability of waste management facilities and the implementation of environment-based waste management policy in Kalibobo. A qualitative descriptive approach was employed through field observations, interviews, and secondary data from BPS and the Environmental Agency (DLH) of Nabire Regency. Findings reveal that Kalibobo serves a population of 15,185 residents (3,796 households) with only one waste container far below the SNI 3242:2008 standard requiring 8–19 units. Service coverage is estimated at less than 20% of the village area. The 3R (Reduce, Reuse, Recycle) implementation rate is critically low at approximately 6%, and no TPS3R or waste bank exists. A significant policy-implementation gap is identified between national targets (30% waste reduction, 70% waste handling by 2025) and on-the-ground realities. The study recommends urgent infrastructure expansion, institutionalization of community-based 3R programs, and acceleration of the 2025–2026 DLH Roadmap to achieve sustainable and environment-based waste management.
