Abstract

Kecamatan Pantai Labu, Sumatera Utara menghadapi masalah pengelolaan sampah yang mempengaruhi kesehatan dan ekosistem. Solusi berkelanjutan diperlukan untuk mengatasi masalah ini. Penelitian mengenai larva lalat tentara hitam/black soldier fly (BSF) terbukti efektif mengolah sampah organik. Studi ini ingin mengetahui faktor apa yang memotivasi masyarakat untuk mengolah sampah. Dengan menggunakan software SPSS, dilakukan terhadap 10 pertanyaan untuk mendapatkan faktor utama yang berpengaruh. Hasil menunjukkan tiga faktor: perencanaan pengelolaan sampah, urgensi masyarakat, dan pengetahuan saat ini. Faktor-faktor tersebut penting untuk meningkatkan kesadaran dalam pengelolaan sampah dan pengembangan manajemen proyek BSF. Sistem Pengelolaan Sampah Berbasis Masyarakat merupakan solusi alternatif di Pantai Labu. Dengan memahami faktor-faktor ini, dapat dilakukan komposting berbasis BSF yang paling tepat di daerah tersebut.

Abstract

Universitas Pertamina has a strong vision in the energy field and is developing environmentally friendly infrastructure and management, including waste management. Considering these efforts, ‘waste-to-energy’ is an interesting concept to be developed. The practical application of this concept is exemplified by refuse-derived fuel (RDF). This research aimed to analyze the potential of waste from Universitas Pertamina’s temporary shelter as raw materials for RDF and identify the potential energy that can be produced. This research began by measuring the generation and composition of waste. Each type of waste is identified for water content, ash content, and calorific value. These findings were used to identify which waste types could serve as RDF raw materials. The water content analysis showed that, except for food waste, all waste types met RDF standards. All waste types also met the RDF ash content standards. The calorific value analysis showed that plastic waste had the highest heating value at 45.6 MJ/kg, followed by rubber waste (40.1 MJ/kg) and styrofoam (35.0 MJ/kg). Calculations for waste generation potential and heating value indicated a total potential calorific value reached 9,895.1 MJ/day. With this significant potential, Universitas Pertamina has the opportunity to develop innovative waste management, especially in producing RDF.

Abstract

Marine tourism in Nusa Penida, Bali, has expanded rapidly over the past decade, attracting large numbers of domestic and international visitors to its renowned dive sites, coral reefs, and coastal landscapes. However, this growth has raised critical safety concerns that threaten both visitor well-being and the sustainability of the destination. This qualitative study draws on an extensive literature review and a structured hypothetical survey framework, designed in August 2024, to examine the systemic challenges in marine tourism safety. Rather than relying on newly collected empirical data, this research synthesizes existing reports, stakeholder commentary, and regulatory reviews to identify ten interrelated categories of risk: weak enforcement, poor infrastructure, unregulated tourism expansion, unsafe operator behavior, limited monitoring, environmental degradation, weather-related risks, lack of safety education, poor incident reporting, and fragmented governance. Through thematic analysis, the study links these issues to feasible and locally adaptive solutions, highlighting the need for integrated zoning, multilingual safety communication, institutional collaboration, and climate-responsive infrastructure. The findings underscore the urgency of developing cross-sectoral, adaptive marine safety governance that aligns tourism growth with environmental resilience and visitor protection. Policy recommendations are proposed for application in other high-risk coastal destinations

Abstract

This research aimed to identify and assess the noise levels at a construction project within X Hospital's B2nd, 5th, 8th, and 9th floors. The study employed a sound level meter according to the Indonesian National Standard (SNI) 7231:2009 to measure noise intensity in the workplace. The primary sources of high noise levels were jackhammers, hammers, portable ventilators, iron-cutting machines, and pipe-cutting tools, with corresponding readings of 148, 114, 95.4, 85, and 85 dB, respectively. To mitigate the potential risks of excessive noise, recommendations were made based on the risk control hierarchy outlined in the Occupational Health and Safety Assessment Series (OHSAS) 18001:2007 for Occupational Health and Safety Management Systems, including equipment substitution, administrative controls, and the use of appropriate personal protective equipment (PPE), such as earplugs. The effectiveness of earplugs, with a noise reduction ratio (NRR) of 30 dB, was highlighted for reducing noise levels below the threshold limit value (TLV) and ensuring worker safety.
