Jurnal ini bertujuan untuk merancang dan mengembangkan sistem turbin angin sebagai alat pengusir hama burung sekaligus sebagai pembangkit listrik alternatif di area persawahan. Penelitian difokuskan pada pemanfaatan energi angin untuk menggerakkan perangkat mekanik penghasil suara (sebagai pengusir burung pipit) serta menghasilkan energi listrik menggunakan generator Nema17 untuk pengisian baterai. Selain itu, penelitian ini bertujuan menganalisis hubungan antara kecepatan angin, desain blade (panjang dan karakteristiknya), putaran turbin, serta tegangan dan daya listrik yang dihasilkan, guna memperoleh performa optimal dalam kondisi lapangan

Abstract

Briquetting represents one of the key technological pathways for biomass utilization, particularly when combined with plastic waste that is otherwise difficult to manage. This study aims to analyze the effect of Calotropis gigantea (Biduri leaves) as a natural binder on the characteristics of briquettes made from corncob charcoal and low-density polyethylene (LDPE) plastic waste.  Corncobs were carbonized at 300-400 °C for approximately 4 hours, and briquettes were formulated with a constant corncob-to-LDPE ratio of 70:30. Five binder compositions (15%, 20%, 25%, 30%, and 35% of total briquette mass) were tested to determine the optimal formulation. Physical and chemical properties including moisture content, ash content, volatile matter, fixed carbon, calorific value, density, and bulk density, were analyzed. The results demonstrated that the 15% binder composition (V1) achieved the best performance, meeting SNI requirements with a moisture content of 2.947%, ash content of 6.790%, volatile matter of 3.536%, fixed carbon of 86.727%, calorific value of 7216.649 cal/g, density of 0.932 g/cm³, and bulk density of 0.326 g/cm³. This research highlights the novelty of employing Calotropis gigantea leaves as a sustainable binder in LDPE-modified biomass briquettes. The findings confirm that natural binders can enhance briquette quality while reducing reliance on synthetic adhesives, offering a viable pathway toward environmentally friendly household energy solutions.

Abstract

The Ciwidey sub-watershed serves as a buffer zone to meet the raw water needs of Bandung Regency. This study aims to assess the hydrological impacts of soil and water conservation techniques and evaluate the combined effects under extreme rainfall on runoff and baseflow dynamics. The Soil and Water Assessment Tool (SWAT) hydrological model was employed to predict flow discharge in the Ciwidey sub-watershed. The methodology included collecting hydrological, climate, and land-use data, delineating watersheds, forming Hydrological Response Units (HRUs), and conducting model calibration, validation, and simulation of a surface runoff. The spatial pattern of the Bandung Regency Regional Spatial Plan (RTRW) for 2016–2036 resulted model simulations predicted a surface runoff of 1,084.36 mm/year under extreme rainfall. The watershed conservation program demonstrates strong implementation of agroforestry and reforestation throughout the watershed region, with 42,313 hectares currently under management with 21 individual conservation projects in 9 districts. The conservation planning program consists of implementation Agroforestry (52.6%), reforestation (39.6%) and 7,8% infiltration well, with Pasir Jambu District and Subbasin 6 emerging as focus area of comprehensive conservation. The study demonstrates that integrating soil and water conservation is crucial for sustainable water resource management and flood risk reduction in rapidly developing regions.
