Abstract

The Pre-Delivery Installation (PDI) Department of PT. XYZ is tasked with carrying out the installation process of imported heavy equipment attachment units, including one of the leading excavator units. Obstacles that arise can affect installation productivity. The gap between the actual installation results of 78 units and the company's target of 156 units requires a solution or resolution to improve the process that can be implemented. Therefore, it is necessary to investigate the wait time associated with decreased productivity, which is the longest component of the installation process. This work has a purpose to analyze lead time of the excavator attachment unit installation process. The method is applied with a time study approach referring to data sheets and observations, then processing lead time data using pie charts, Pareto diagrams, and fishbone diagrams. Furthermore, we review the planning calendar, realization, and improvement engineering. Reduction is carried out by providing additional work personnel and procuring sanding machine tools to reduce the installation and critical time of the planning calendar. The realization condition for 562 minutes with the implementation of improvement engineering is reduced to 318 minutes. Thus, it can speed up implementation time of the excavator attachment in unit installation process to 224 minutes or 44%.

Abstract

The Free Nutritious Meals Program (MBG), launched in January 2025, is one of the national priority programs with a budget of Rp223 trillion in 2026. However, its centralized implementation through the Nutrition Fulfilment Service Units (SPPG) faces various serious systemic problems. By the end of 2025, there were more than 20,000 reported cases of food poisoning, two fatalities, as well as chronic distribution delays, substandard nutritional quality, targeting inaccuracies, and corrupt practices involving non-essential actors. This article aims to formulate a school-based MBG decentralization model with three main pillars: (1) the phased elimination of all SPPGs, (2) the direct disbursement of funds from the National Nutrition Agency (BGN) to schools without intermediaries, and (3) a ban on the involvement of non-essential institutions in the distribution chain. The methods used include a projected case study with comparative policy analysis and a systematic literature review of 30 indexed journals from the past 10 years. The proposed model channels funds directly from the BGN to school accounts; preparation, cooking, and distribution are carried out on school premises with the rotating involvement of parents; raw material suppliers are selected from local farmers/vendors through a rotation system; monitoring is conducted by both the school committee and parents; and meal portions are adjusted according to the actual number of students present. This model recommends the phased discontinuation of the SPPG over a 6-month period, as well as the closure of the entire distribution chain involving non-essential actors. The main recommendation is a limited pilot program in 20–30 non-urban schools as the basis for reforming the national MBG governance system
