Abstract

SMKN 1 Gunung Sindur menghadapi tantangan keterbatasan fasilitas greenhouse sebagai sarana pembelajaran lingkungan berkelanjutan. Kondisi ini menghambat upaya sekolah menuju predikat Adiwiyata Unggulan dan membatasi pengalaman praktik langsung bagi para siswa. Untuk mengatasi permasalahan tersebut, dilaksanakan Program Pengabdian kepada Masyarakat (PkM) melalui skema Kerja Kerja Sama Dalam Negeri (KDN) yang mengintegrasikan kolaborasi antara Universitas Mercu Buana dan Pemerintahan Desa Rawa Kalong. Program ini bertujuan meningkatkan pemahaman Tim Adiwiyata mengenai pendidikan lingkungan, sekaligus membangun fasilitas greenhouse sebagai laboratorium mini guna mendukung pencapaian Adiwiyata Unggulan secara berkelanjutan. Metode pelaksanaan kegiatan meliputi pelaksanaan workshop pendidikan lingkungan, diskusi perencanaan desain teknis, konstruksi fisik greenhouse, serta tahap monitoring dan evaluasi menggunakan instrumen kuesioner dan observasi lapangan. Hasil evaluasi menunjukkan bahwa 92% peserta menilai kegiatan workshop sangat bermanfaat, yang disertai dengan peningkatan pemahaman signifikan terkait keberlanjutan lingkungan. Fasilitas greenhouse yang berhasil dibangun kini berfungsi optimal sebagai laboratorium praktik, meningkatkan keterampilan teknis siswa, serta memperkuat kesiapan sekolah dalam meraih Adiwiyata Unggulan. Secara lebih luas, program kolaboratif ini berkontribusi nyata pada pencapaian Indikator Kinerja Utama (IKU) perguruan tinggi dan mendukung ketercapaian SDGs, khususnya tujuan 4 (pendidikan berkualitas), tujuan 11 (komunitas berkelanjutan), dan tujuan 13 (aksi iklim).

Abstract

The nickel smelting industry in Indonesia generates substantial volumes of slag waste, which pose significant environmental risks if not managed effectively. This study aims to develop a utilization model for nickel slag employing a dynamic systems approach over the 2025–2034 time horizon. The research utilizes secondary data obtained from smelter company reports, relevant literature, and scenario simulations constructed using Powersim. The simulation outcomes reveal a progressive increase in slag generation that is disproportionate to the available processing capacity, resulting in the accumulation of unmanaged nickel slag. Scenario-based optimization demonstrates that enhancing processing capacity by approximately 5%–10% annually can markedly reduce the volume of unmanaged slag. These results underscore the importance of adopting a circular economy framework to support sustainable nickel slag utilization within the smelting industry.

Abstract

Geopolitical tensions in the Middle East have increased uncertainty in petrochemical and polypropylene supply, reducing plastic raw material availability and forcing plastic injection companies to improve process efficiency, minimize scrap, and reduce production losses. In automotive component manufacturing, the Cover Defroster product still faces short shot defects caused by incomplete molten plastic flow into the mold cavity. Many injection molding companies also still rely on trial-and-error machine settings, which increases material waste, setting time, and production cost. This study aims to optimize injection molding parameters using the Taguchi method and Moldflow simulation to eliminate short shot defects and minimize cycle time.  This research used a computer simulation-based experimental design. The product studied was a polypropylene type LA880T. Four process parameters were tested using an Orthogonal Array L16, namely injection pressure, mold temperature, melt temperature, and injection time. Moldflow Insight was used to simulate material flow, while ANOVA, Tukey test, and Signal-to-Noise Ratio with the Smaller-the-Better approach were used to analyze cycle time performance.  The simulation showed that trials 1 to 4 produced short shot defects and were rejected. ANOVA results showed that injection time had a significant effect on cycle time, while injection pressure, mold temperature, and melt temperature had no significant effect. The best parameter combinations were trials 6, 12, and 15, which produced good products without short shot defects and achieved the shortest cycle time of 24.12 seconds. The integration of Taguchi and Moldflow effectively supports parameter optimization, reduces defect risk, and improves injection molding process efficiency.

Abstract

SMKN 1 Gunung Sindur contributes significantly to the preparation of vocational students with the technical and professional competencies required by industry. To improve this effort, it works together with Universitas Mercu Buana on a community service program that integrates character education with occupational safety and health (OSH), focusing on how to properly use personal protective equipment (PPE). The program is in line with the key performance indicators for higher education, which help build stronger partnerships between higher education institutions and vocational schools. Activities were designed from an industrial engineering perspective, emphasizing ergonomics, safety management, and a safety-oriented work culture, delivered through interactive training, video demonstrations, and structured discussions. Program outcomes were evaluated by using a post-training questionnaire (P1–P5). The results showed that 70.5% of students had not previously received similar training; 97% perceived the materials as highly beneficial; 91% found the content easy to understand; 90% reported engaging delivery; and 82% considered the training duration sufficient. Overall, the program improved students’ understanding and correct practice of PPE application, strengthened OSH awareness, and fostered positive attitudes towards safe work behavior. This initiative supports graduate employability and provides a practical model for sustainable collaboration between higher education institutions and vocational schools.

Abstract

The gacorslot folding gate is a middle frame flanked by cross bars on the back of the shop door which has a higher level of strength than the body of the door and has better security. The U folding profile is made by a plastic deformation rolling process in which the plate is passed between the pressing roll and the sliding roll. Flat plates are used from the base material of metal plates with varying plate thickness where the metal forming process uses a cold working process. Factors that affect the results of rolling are roll dimensions, machine capacity, roll pressure lever settings and others. The thickness of the plate that can be rolled by the machine, the amount of force exerted on the roll gap, the evenness of the roll surface both vertically and horizontally and the alignment of the roll gap. The thicker the material with a large pressure spacing can affect the forming process so that it enlarges the largest angular deviation of 0.761 mm at a pressure spacing of 0.0 mm. A thicker material with a large pitch can enlarge the wing opening so that both wings bend imperfectly making the height deviation increase by 18.58 mm at a pitch of 0.0 mm. Thinner material with a large press distance at the start of the roll affects the flange width so that the rolling force exerted on the contact gap between the roll and the workpiece side is unbalanced. Get the largest size b- (8.030 mm) 0.0 mm pressure distance and b+ (7.843) 0.15 mm pressure distance.
