Make To Order (MTO) is a manufacturing strategy that executes different orders based on consumer demand. In the MTO strategy, products are produced only when there are orders from consumers. In this MTO system, the production process starts when an order arrives and starts with planning raw materials which takes a long time and causes a long lead time (MLT). Long MLT often causes production delays and forces companies to pay more overtime. Companies must adopt a production system that can fulfill a variety of orders and has a fast response time. In this research, a case study was conducted on a shoe and bag manufacturing company in the fashion industry. This study aims to implement a mass customization manufacturing (MC) strategy to minimize MLT. The MC strategy uses the concept of a production process based on orders and inventory. This study is expected to reduce MLT so that production delays do not occur again. The results of this study indicate that relocation of the customer order decoupling point (CODP) can reduce MLT from 30 days to 26 days. By reducing this, production delays can be overcome. In terms of costs, this production system is lower than before and the profits are higher.

The Ministry of Health of the Republic of Indonesia has established standard rules for the quality of outpatient service in hospitals. One indicator of the quality of outpatient services at a hospital is the patient's waiting time to be served either by a specialist or other services such as a pharmacy. Respira Hospital Yogyakarta is a special pulmonary and respiratory hospital in Yogyakarta that continues to improve the quality of its services. Based on the results of observations and interviews it is known that in terms of waiting time, patients at Respira Hospital Yogyakarta still have to wait to get service. Examples of queues that occur include patients waiting for a specialist doctor's examination for around 75 to 90 minutes. waiting at the pharmacy and cashier for up to 60 minutes or more. This study attempts to evaluate the waiting time for outpatient services at Respira Hospital Yogyakarta using a simulation. Based on the simulation results, it is known that the patient's waiting time in the system is 217.33 minutes and the longest waiting time is in the pediatric polyclinic and pharmacy departments. After the scenario implementation were made, namely in the pediatric polyclinic and pharmacy sections, the waiting time decreased to 177.19 minutes. This means that evaluations carried out using simulations can help hospitals reduce waiting time for outpatients

Waste is an unresolved government problem. The largest waste collection site (TPS) in Yogyakarta, TPS Piyungan, is starting to get tired of collecting waste from various corners of Yogyakarta. One of the efforts to overcome this problem, the government instructed the Waste Sorting Movement. Based on the Ministry of Environment and Forestry (KLHK), the composition of waste in Indonesia is dominated by organic waste, which reaches 57% of the total landfill. Organic waste can be processed by cultivating BSF Black Soldier Fly (Hermetia Illucens). BSF is a black fly whose maggots (larvae) can degrade organic waste. Maggots (maggots) produced from black fly eggs are very active in eating organic waste. This bioconversion process by maggots can degrade waste more quickly, is odorless, and produces organic compost, and the larvae can be a good source of protein for poultry and fish feed. Maggots have the ability to break down organic waste 2 to 5 times their body weight for 24 hours. One kilogram of maggot can consume 2 to 5 kilograms of organic waste per day. Maggots that have become prepupae and BSF fly carcasses can still be used as animal feed because they are rich in protein. The cocoons can also be used as fertilizer. This process was socialized to Sub Urban groups in the Padukuhan Dukuh, Sidoharjo, Ngaglik, Sleman areas, as a response to the unresolved waste problem. Activities are carried out by: Carrying out outreach related to waste problems and BSF maggot cultivation, Carrying out waste sorting training, Carrying out training on BSF maggot cultivation, Distribution of rubbish bins to residents (partners) as containers to accommodate organic waste, Creation of organic waste storage areas, Construction of BSF Maggot houses , Breeding activities, maintenance and harvesting of BSF maggots, Packaging of BSF Maggot products, Sales of BSF Maggot products

Simulation is one of the tools to solve the problems in a system, including hospital systems. The hospital has objectives and entities that are different from other systems, namely service to patients (humans) primarily, so making some decisions requires consideration due to the complexity of the variables within them. This preliminary study will discuss what problems might occur in the hospital and how the application of the simulation in solving the problem. Based on observations and interviews conducted, it is known that there are four issues: 1.) hospital services 2.) labor allocation (nurses) 3.) capacity and number of rooms/beds 4.) drug supply. Based on the literature search results, it is known that the simulation has the ability to solve these problems. The results of this literature review will then be used as a basis for developing simulation models in hospitals which are the object of research.

Dalam aktivitas distribusi, terutama bagi UMKM seperti Nara Katering, penentuan rute merupakan aspek krusial yang memengaruhi biaya operasional dan kepuasan pelanggan. Penelitian ini mengusulkan pendekatan hybrid heuristic yang terdiri dari empat tahapan: pengklasteran, pengurutan rute, perbaikan rute, dan penentuan biaya operasional kendaraan. Tahap pengklasteran menggunakan algoritma sweep, sedangkan pengurutan rute menggunakan nearest insertion heuristic, dan perbaikan rute menggunakan algoritma 2-opt dengan dukungan MATLAB. Biaya operasional kendaraan dihitung berdasarkan standar Departemen Pekerjaan Umum 2005. Hasil penelitian menunjukkan peningkatan signifikan dalam efisiensi rute distribusi, dengan jarak tempuh yang lebih pendek sebesar 12,20% dibandingkan dengan rute aktual. Meskipun pengurutan rute berdasarkan algoritma nearest insertion heuristic sedikit lebih panjang dibandingkan dengan rute aktual, total biaya operasional kendaraan menunjukkan penghematan yang signifikan. Dua model sistem pengupahan dipertimbangkan: sistem pengupahan per titik dan sistem pengupahan dengan Upah Minimum Regional (UMR) per bulan. Sistem pengupahan per titik direkomendasikan karena memberikan keuntungan yang lebih besar bagi UMKM Nara Katering, dengan biaya operasional kendaraan sebesar Rp204.667,01/hari dan keuntungan Rp85.322,99/hari. Sementara itu, sistem pengupahan berdasarkan UMR per bulan menghasilkan total biaya operasional kendaraan sebesar Rp251.446,01/hari dengan keuntungan Rp38.553,99/hari. Rekomendasi ini didasarkan pada keuntungan yang lebih besar yang dapat diperoleh dengan sistem pengupahan per titik.

Optimizing work movements is crucial for enhancing efficiency and reducing injury risks in industrial environments. Methods like Methods-Time Measurement (MTM), Work Factor (WF), and Maynard Operation Sequence Technique (MOST) are commonly used to analyze and optimize the workstations. However, there remains a lack of accessible tools for rapid and accurate time measurement. This study aims to develop a web-based and Android application designed to assist both students and professionals in calculating work times and optimizing movements (such as: material handling) more efficiently. The application was evaluated using the WebQual method, focusing on usability quality, information quality, and interaction quality. Evaluation results yielded scores of 82.3% for usability, 85.7% for information quality, and 80.5% for interaction quality. Validity and reliability tests demonstrated a Cronbach's Alpha coefficient of 87%, indicating very high reliability. The integration of MTM within this application has proven effective in accelerating work time calculations compared to manual methods and in improving movement efficiency, which directly contributes to reducing injury risks.

Sustainable settlement design necessitates the incorporation of environmental carrying capacity determined by ecosystem services. In border areas like the Sota Border Area (KPN) in Papua, ecological pressures intensify as a result of population expansion and economic endeavours. This study assesses the environmental carrying capacity and resilience of settlements through an ecosystem services framework, comparing conditions in 2019 and 2024 to evaluate the impact of development plans. The analysis focuses on five key ecosystem services: food provision, clean water supply, water flow regulation and flood control, disaster protection, and air quality maintenance. Data collection involved field surveys, remote sensing, and GIS-based spatial overlay analysis to map land use changes and ecosystem service values. Results in 2019 showed residential development concentrated in zones with high ecosystem service values, such as food provision (771.7 ha in SUB BWP 2) and clean water supply (742.98 ha in SUB BWP 3). Development in low-lying areas prioritized flood regulation (460.1 ha in SUB BWP 1) and disaster protection (560.7 ha in SUB BWP 1). By 2024, developed land in the very high clean water supply zone of SUB BWP 1 increased sharply from 0.10 ha to 28.86 ha. This research highlights the critical need to incorporate ecosystem service data into settlement planning to sustain environmental capacity and enhance border region sustainability
