Abstract

This research investigates the intersection between geography, urban development, and heritage preservation in Lahat Regency, South Sumatra, Indonesia, using Lubuk Sepang and Bangke villages as case studies. Lubuk Sepang's river proximity and Bangke's mountainous terrain distinctly influence settlement patterns, heritage conservation challenges, and developmental pressures. Employing a mixed-methods approach—including fieldwork, geospatial mapping—the study identifies how geographical features impact heritage sites, community dynamics, and conservation strategies amid rapid urbanization.The findings highlight that settlements near rivers face threats from infrastructure expansion, erosion, and environmental degradation, risking loss of cultural heritage linked closely to water resources. In contrast, mountainous settlements struggle with deforestation, landslides, and infrastructural encroachment, threatening ecological integrity and traditional heritage. Effective heritage conservation necessitates integrating geographical considerations into urban planning, adopting technological innovations such as GIS (Geographic Information System) and digital archiving, and fostering active community participation. The study provides actionable recommendations to harmonize urban growth and heritage preservation in geographically diverse areas.

Abstract

Proyek perbaikan jalan aspal hotmix memiliki berbagai potensi bahaya yang dapat menimbulkan risiko terhadap keselamatan dan kesehatan kerja (K3) serta kelancaran pelaksanaan proyek. Penelitian ini bertujuan untuk mengidentifikasi, menilai, dan mengendalikan risiko pada setiap tahapan pekerjaan menggunakan pendekatan Hazard Identification, Risk Assessment, and Risk Control (HIRARC), yang meliputi identifikasi bahaya, penilaian tingkat risiko berdasarkan kemungkinan dan dampak, serta penerapan langkah pengendalian yang sesuai. Hasil penelitian menunjukkan bahwa risiko tinggi banyak ditemukan pada tahap penghamparan dan pemadatan aspal hotmix, terutama akibat paparan suhu tinggi, pergerakan alat berat, dan kondisi lingkungan kerja yang dinamis. Secara keseluruhan, teridentifikasi 25 potensi bahaya dari 10 aktivitas kerja yang menghasilkan 33 risiko, terdiri atas 8 risiko ekstrem (24,24%), 15 risiko tinggi (45,45%), 8 risiko sedang (24,24%), dan 2 risiko rendah (6,06%), yang mencakup risiko fisik, kimia, ergonomi, dan lingkungan. Setelah penerapan pengendalian teknis dan administratif, seperti penggunaan alat pelindung diri, pengaturan zona kerja, dan briefing keselamatan, tidak lagi ditemukan risiko kategori ekstrem dan tinggi, dengan distribusi risiko berubah menjadi 17 risiko sedang (51,51%) dan 16 risiko rendah (48,48%), serta penurunan kumulatif Risk Rating (RR) dari 278 menjadi 103. Kebaruan penelitian ini terletak pada penerapan HIRARC secara sistematis, komprehensif, dan kuantitatif, yang mampu memetakan risiko secara rinci dan membuktikan efektivitas pengendalian K3 pada pekerjaan hotmix yang berisiko tinggi.

Abstract

The conversion of Internal Combustion Engine (ICE) motorcycles into plug-in hybrids is a practical solution for improving fuel efficiency and reducing exhaust emissions in two-wheeled vehicles. This study aims to present the design of an electric motor powertrain for plug-in hybrids, as well as to measure fuel efficiency and estimate the potential annual reduction in CO₂ emissions. Fuel efficiency testing was conducted through an on-road test using an urban driving scenario. The results showed that converting a 2018 Honda Beat motorcycle to a plug-in hybrid improved fuel efficiency by 21.4%, as indicated by an increased travel distance of 36 km. This improvement in fuel efficiency has the potential to reduce CO₂ emissions by 110.1 kg per year for a single converted motorcycle. Currently, the cost of converting a motorcycle to a plug-in hybrid is IDR 15,950,000. This cost is still higher compared to the incentives currently available from the government, making it a major obstacle in attracting public interest.
