Abstract

Regulasi nasional mengamanatkan bangunan yang andal dan aman melalui Sertifikat Laik Fungsi (SLF), namun implementasinya di Kabupaten Bogor menghadapi berbagai tantangan. Penelitian ini bertujuan menganalisis kinerja implementasi SLF berbasis aplikasi Sistem Informasi Manajemen Bangunan Gedung (SIMBG), mengidentifikasi faktor yang memengaruhinya, dan merumuskan strategi perbaikan. Metode penelitian yang digunakan adalah pendekatan campuran (mixed-method) yaitu menggabungkan analisis kuantitatif terhadap 2.440 data Persetujuan Bangunan Gedung (PBG) dan 197 permohonan SLF dari basis data SIMBG dengan analisis kualitatif melalui studi kasus, wawancara, dan analisis dokumen. Hasil penelitian menunjukkan kinerja implementasi belum optimal, ditandai oleh kesenjangan kepatuhan sebesar 24,6% untuk bangunan skala signifikan dan kegagalan fungsi jalur cepat (fast track) 3 hari. Faktor utama penyebab rendahnya kepatuhan adalah kurangnya sosialisasi dan kesadaran pemilik bangunan, serta kendala prosedural dalam SIMBG. Sementara itu, keterlambatan pada proses jalur standar (standard track) 28 hari disebabkan oleh ketidaklengkapan dokumen pemohon dan kapasitas teknis internal pemerintah daerah yang terbatas. Meskipun demikian, analisis SWOT menempatkan implementasi SLF pada kuadran pertumbuhan agresif, mengindikasikan potensi perbaikan yang sangat besar. Rekomendasi strategis difokuskan pada sosialisasi terstruktur, penguatan regulasi daerah melalui Peraturan Bupati, peningkatan efisiensi, pengembangan ekosistem jasa konstruksi lokal, dan advokasi kebijakan di tingkat nasional.

Abstract

This study aims to investigate students’ learning obstacles in understanding Green Chemistry within the context of a soap-making activity. As sustainability becomes an increasingly important issue in science education, it is essential to understand how students engage with environmentally oriented chemistry concepts. This study employs qualitative case study approach. The participants consisted of five grade XI students (second-year high school), comprising two boys and three girls. The interviews were conducted at a private school in Bandung. Data were collected through semi-structured interviews with five main questions. The responses were analyzed using thematic analysis to identify key themes related to students’ learning challenges in understanding green chemistry, which were categorized into five main themes. The findings reveal that students face significant challenges in understanding Green Chemistry, particularly due to abstract concepts, limited classroom engagement, and teacher-centered instruction. Moreover, students often struggle to connect the theoretical principles of Green Chemistry with real-life applications, such as waste reduction or the use of renewable materials in everyday chemical processes. These findings highlight the importance of designing more interactive, context-based, and student-centered learning strategies. It is expected that the results of this study can serve as a foundation for developing instructional designs that better support students’ understanding of sustainability-oriented chemistry.

Abstract

This study aims to utilize banana pseudostem and coconut pulp waste as raw materials for biomass briquettes, evaluate their physical and thermal characteristics, and assess their potential as alternative fuel sources. The research methods included drying, grinding, mixing, molding, and briquette testing. Characterization was conducted through hardness testing using a digital sclerometer, morphological and particle size analysis using a digital microscope, calorific value measurement using a bomb calorimeter, and thermal degradation analysis using Thermogravimetric Analysis (TGA). The hardness test showed that pure banana pseudostem briquettes had the highest compressive strength according to the P3HH standard, while the addition of coconut pulp tended to reduce it. Increasing the proportion of coconut pulp produced larger average particle sizes, affecting briquette porosity. The highest calorific value, 16,829.73 J/g, was obtained from a 50:50 composition, indicating that the oil and lignin content in coconut pulp contributes to combustion energy. TGA analysis revealed that briquettes with higher banana pseudostem content exhibited greater heat resistance, while those with more coconut pulp ignited faster and left less residue. In conclusion, briquettes made from banana pseudostem and coconut pulp can be used as an alternative solid fuel, with compositions adjustable according to the desired energy output and combustion characteristics.

Abstract

Clean water is a fundamental human need that supports public health, social activities, and sustainable economic development. Desa Girimukti, located in the UNESCO Global Geopark Ciletuh–Palabuhanratu area, faces increasing clean water demand due to population growth and tourism development, while also being exposed to environmental and operational risks such as landslides, floods, and source reliability issues. This study aims to plan a risk-based clean water distribution system capable of ensuring service reliability and sustainability. The research applied a quantitative–descriptive approach, including population projection, water demand analysis, risk identification, and hydraulic analysis using the Hazen–Williams equation. The results indicate that the projected water demand at the end of the planning period is approximately 9 L/s, while the available water sources from groundwater wells and surface water provide sufficient capacity. Risk analysis shows that surface water pollution represents the highest risk, requiring appropriate treatment and mitigation measures. The designed centralized distribution system with a main reservoir meets technical criteria for velocity, headloss, and residual pressure. Overall, the proposed system is technically feasible and capable of mitigating key risks in the study areaThe abstract briefly contains a description of the problem and research objectives, methods used, and research results.
