Abstract

Penataan saluran air harus dilakukan dengan sebaik mungkin agar pada saat musim hujan tidak terjadi genangan atau banjir. Genangan air walaupun sesaat akan sangat mengganggu aktifitas masyarakat. Selain itu potensi kerusakan lingkungan hidup dan kesehatan masyarakat juga mengancam warga perkotaan. Keadaan saluran air yang kurang mendukung dan sampah menambah masalah terhadap genangan air di saluran yang kotor dan berbau, yang harus segera ditangani dengan tepat dan bijaksana. Sampah adalah sisa buangan dari suatu kegiatan atau barang yang sudah tidak digunakan lagi, namun dapat di daur ulang menjadi barang yang bernilai. Sampah organik adalah sampah yang ramah lingkungan bahkan bisa diolah kembali menjadi suatu yang bermanfaat bila dikelola dengan tepat. Perumahan Taman Aloha terletak di desa Suko Sukodono Sidoarjo, warga yang tinggal banyak yang memanfaatkan air tanah sebagai sumber mata air selain air yang disediakan oleh Perusahan Daerah Air Minum (PDAM). Dengan keadaan saluran air yang kotor dan tergenang serta sampah yang kurang terkelola dengan baik menyebabkan kualitas air sumur/ air tanah warga tidak baik. Hal ini membebani bumi dan mengancam kerusakan lingkungan hidup. Oleh karena itu harus segera dilakukan tindakan untuk menyelamatkan bumi mulai dari kelompok kecil di lingkungan sekitar perumahan Taman Aloha dengan memutus jalur distribusi sampah dengan mengolahnya  di tingkat rumah tangga. Dengan pelatihan pembuatan Eco Enzyme, akan menjadi solusi dalam merawat bumi dan lingkungan hidup baik tanah, air maupun udara terutama perumahan Taman Aloha. Sekaligus memperdayakan warga dengan pembuatan produk turunan Eco Enzyme berupa sabun detergen dan pembersih lantai sebagai pengganti bahan kimiawi/ sintetis, yang dapat dijual untuk meningkatkan ekonomi warga.

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.

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

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 is a company engaged in the production and distribution of industrial equipment, with one of its main products being the Medical System Vacuum. This study analyzes the problems in the Purchasing Department related to the production process, by identifying key challenges such as delays in Bill of Materials (BOM) creation due to queues for damage analysis and inefficiencies in the workflow from Sales Order (SO) to Work Order (WO). This study aims to identify and minimize delays inthe Medical System Vacuum production process at PT. Intidaya Dinamika Sejati using the Failure Mode and Effects Analysis (FMEA) and Value Stream Mapping (VSM) methods. FMEA is used to determine the risk of failure based on the Risk Priority Number (RPN) value, while VSM is used to analyze the value stream and production lead time. The results show that long queues in the Bill of Materials (BOM) damage analysis have the highest RPN value of 432, followed by delays in material arrival (RPN 280) and Purchase Order approval (RPN 210). The total lead time reaches 177 hours, with a non-production time contribution of 81%.
