Abstract

This paper highlights the importance of Photovoltaic Solar Power Systems (SPP) in supporting sustainable energy. SPP converts sunlight into electricity, which not only reduces the carbon footprint but also enhances energy independence and supports environmental sustainability. Thus, this technology plays a crucial role in the transition towards green energy. Case studies in this journal demonstrate the significant contribution of SPP to green energy worldwide, showing how the implementation of SPP can reduce dependence on fossil fuels and minimize greenhouse gas emissions. The implementation of SPP in campus life is also a concern, where its application can create a more environmentally friendly and energy-independent environment. Integrating SPP into campus energy policies and infrastructure is a critical step to mitigating the impacts of climate change and ensuring a sustainable energy future. With proper development and application, SPP can become a major pillar in the global strategy to achieve long-term sustainability goals.

Abstract

Metal casting is one of the manufacturing methods widely used to produce components with complex shapes and high precision. This study aims to evaluate the use of alternative molds based on a mixture of silica sand and bentonite in aluminum casting. Variations in the composition of silica sand and bentonite are applied in the casting process to observe their effects on the surface quality of the casting results and the efficiency of the production process. The results of field observations show that the optimal composition consists of 85% silica sand, 10% bentonite, and 5% graphite, which produces a mold mixture with good consistency, is not easily cracked, and is able to replicate pattern details with high precision. In addition, molds with this composition are easier to shape and have good resistance during the casting process, thereby reducing the risk of mold failure. Thus, molds based on silica sand and bentonite have the potential to be a more efficient and environmentally friendly alternative in metal casting technology.

Abstract

PT. Intidaya Dinamika Sejati adalah perusahaan yang bergerak di bidang produksi dan distribusi peralatan industri, dengan salah satu produk utamanya adalah Medical System Vacuum. Studi ini menganalisis permasalahan di Departemen Purchasing terkait proses produksi, dengan mengidentifikasi tantangan utama seperti keterlambatan dalam pembuatan Bill of Materials (BOM) akibat antrean analisis kerusakan serta ketidakefisienan dalam alur kerja dari Sales Order (SO) ke Work Order (WO). Melalui pengamatan langsung,analisis data kegagalan, dan wawancara dengan ahli, ditemukan bahwa waktu produksi normal per unit adalah tiga minggu. Untuk meningkatkan efisiensi, beberapa solusi diusulkan, termasuk digitalisasi dan otomatisasi analisis BOM, optimalisasi pengadaan material melalui kerja sama dengan pemasok, penerapan sistem persediaan Just-In-Time (JIT), serta pemantauan pengiriman material secara real-time. Peningkatan koordinasi antar divisi juga menjadi faktor penting melalui penyederhanaan prosedur, penerapan sistem komunikasi digital, dan pelatihan lintas divisi. Selain itu, untuk mengatasi keterlambatan proyek, diperlukan penjadwalan ulang dengan waktu buffer yang lebih realistis, pemantauan progres secara berkala, dan penerapan analisis risiko secara proaktif. Langkah-langkah ini diharapkan dapat meningkatkan efisiensi produksi, mengurangi biaya dan waktu, serta meningkatkan kepuasan pelanggan, sehingga pada akhirnya memperkuat posisi kompetitif PT. IDS di pasar.

Abstract

The research gap that this study aims to fill is: increasing the reliability of the previously created simulation model and adopting a representation of uncertainty in the Basic Robochop production process time. This study analyzes the production process time of one basic Robochop unit using ARENA software-based simulation. The Basic Robochop (seven units) is modeled using an activity cycle diagram representing the arrival of its components based on historical data. The model then integrates the components into the production process until completion. The time between the arrival of 50 components of one Basic Robochop product is modeled with a random EXPO(1) minute, the 50 components are then assembled in the Basic Robochop production process which is modeled based on historical data of the previous manufacture of 7 Robochops with one worker, namely 129 + EXPO(1,380) minutes. The model produces a square error value of around 3%. The optimal number of replications obtained was 1,833, after five initial replications were carried out randomly. The simulation results show a decrease in process time from 24,670 minutes to 1,096 minutes in the alternative scenario.

Abstract

The cracker industry is an important part of Surabaya’s traditional culinary heritage and is largely operated by micro-scale enterprises with simple management systems. One such enterprise is the cracker business owned by Mrs. Ponining in East Surabaya. This business faces several challenges, including non-standardized production processes, inconsistent quality control, unsystematic financial record-keeping, and product packaging without a clear brand identity. This community service program aims to enhance the capacity of Mrs. Ponining’s cracker business through assistance in production, business management, and marketing. The interventions include the implementation of simple production standard operating procedures (SOPs), the application of 5S principles to improve workplace organization and hygiene, mentoring in simple yet systematic financial record-keeping, and the development of product packaging and labeling as business identity. Several constraints were encountered during implementation, such as limited time availability and the persistence of traditional business practices. However, these challenges were addressed through gradual mentoring and hands-on assistance tailored to the conditions of micro-scale enterprises. The results indicate improvements in product quality consistency, production efficiency, financial management orderliness, and product packaging. This program is expected to support the sustainability of the cracker business and serve as a model for empowering traditional micro-scale food enterprises in urban areas.
