Abstract

Traffic congestion in Indonesian cities is a major problem, due to uneven mobility. The Jagir Wonokromo intersection, one of the busiest intersections in Surabaya, experiences traffic congestion during rush hour. This congestion can have a variety of negative impacts, such as air pollution and queuesat each intersection. This study analyzes the traffic congestion problems at the Jagir Wonokromo intersection and proposes the appropriate improvement scenario. A simulation design was developed to test three traffic congestion improvement scenarios at the Jagir Wonokromo intersection in Surabaya. The study sample was 40 vehicles that passed through during rush hour. The simulation results showed that scenario 3 is the most appropriate improvement scenario. This scenario successfully reduced the time in the system by 20.2% compared to the initial condition. The impact of scenario 3 is that traffic congestion at the intersection is reduced, but the travel time of vehicles from the DTC direction to Jalan Jagir Wonokromo also increases. Scenario 3 is considered to be in accordance with the conditions of the intersection and can be easily implemented. The study of traffic congestion at the Jagir Wonokromo intersection offers opportunities for the government and the public to address traffic congestion with effective simulation of improvement scenarios.

Abstract

The SDGs, launched by the UN in 2015, replaced the MDGs with 17 goals, focused on eliminating poverty, environmental protection, and global prosperity. PT. Dharma Electrindo Manufacturing adopts environmentally friendly technology to save energy and reduce emissions, supporting SDGs. Without the SDGs, there is a need for innovation in manufacturing technology to support SDGs 8, 12, and 13. This study will improve the sustainability of the industry. This research analyzes the effectiveness of energy and environmental improvements at PT. DEM in supporting SDGs. This research design uses a descriptive qualitative approach with a Plan-Do-Check Action cycle to improve energy efficiency and reduce emissions at PT. Dharma Electrindo MFG, with data collected through questionnaires, checklists, and monitoring. Studies show the SDGs are effective for some goals, but cost and weather dependency hinder the efficiency of innovative technologies. The application of efficient technology and PDCA methodology at PT. DEM improves energy and environmental management, reduces emissions by 12% per year, and increases operational efficiency. The implementation of LED lights, automatic watering systems, and renewable energy technology supports SDGs by reducing electricity consumption by 21,790.12 kWh. Theory and practice show PDCA technology supports energy efficiency and the SDGs.

Abstract

Dokumen Penelitian ini bertujuan untuk menganalisis penerapan green manufacturing pada proses produksi Cocoa Butter Substitute (CBS) di PT Unilever Oleochemical Indonesia (UOI) sebagai bagian dari upaya mewujudkan industri oleokimia berkelanjutan. Metode penelitian yang digunakan adalah studi kasus dengan pendekatan kuantitatif dan kualitatif melalui penerapan Green Manufacturing Index (GMI) dan Life Cycle Assessment (LCA) berbasis ISO 14040. Hasil penelitian menunjukkan bahwa seluruh aktivitas produksi, mulai dari perencanaan, pengadaan, distribusi, hingga proses manufaktur, telah menerapkan prinsip keberlanjutan dengan efisiensi energi mencapai 18% dan penurunan emisi gas rumah kaca sebesar 15%. Penerapan konsep 6R (Reduce, Reuse, Recycle, Recovery, Redesign, dan Remanufacturing) serta model simbiosis agroindustri terbukti mendukung efisiensi sumber daya dan kebijakan zero waste. Selain itu, inovasi hijau yang dilakukan melalui optimalisasi proses hidrogenasi, digitalisasi energi, dan formulasi bahan baku lokal berhasil meningkatkan efisiensi biaya serta mengurangi dampak lingkungan. Berdasarkan hasil Analisis Mengenai Dampak Lingkungan (AMDAL), seluruh kegiatan produksi berada pada kategori dampak rendah (EII = 0,28). Dengan demikian, implementasi green manufacturing di UOI tidak hanya memperkuat kinerja ekonomi dan sosial, tetapi juga berkontribusi nyata terhadap pencapaian target keberlanjutan global.
