This study aims to analyze the shoe production process from an operational management perspective at PT. XYZ. The focus of the research is directed at the stages of the production process and the management of raw materials in supporting the smooth running and efficiency of production activities. This research uses a descriptive qualitative approach carried out through an Internship Experience Practice (PPL) at PT. XYZ. Data was collected through direct observation of production activities, interviews with relevant parties in the production department, and supporting documentation. The data obtained was analyzed by describing the production process flow, raw material management system, and production process control, then linked to the concept of operational management. The results showed that the shoe production process at PT. XYZ consisted of several interrelated stages, starting from raw material management to the main production process. The company has implemented a fairly structured operational management system, characterized by the recording of raw materials, the separation of materials by type, and the application of the First in First Out (FIFO) method to maintain material quality and smooth production. However, several operational obstacles were still found, such as limited production time, suboptimal coordination between departments, and the potential for defective products in the production process. The implementation of operational management at PT. XYZ has supported the shoe production process quite effectively, particularly in raw material management and production control. Nevertheless, improved coordination and continuous evaluation of the production process are needed to enhance operational efficiency and product quality.

Coffee husk is an agro-industrial waste with significant potential to be utilized as a renewable energy source through the fast pyrolysis process. This study aims to analyze and optimize gas production from the fast pyrolysis of coffee husk biomass using a screw reactor through single-particle-based Computational Fluid Dynamics (CFD) simulations. The simulations were conducted by varying the operating temperature at 500°C, 600°C, and 700°C to examine pressure distribution, heat transfer, particle temperature, and the formation of pyrolysis products, namely bio-oil, biogas, and biochar. The modeling was performed using COMSOL Multiphysics 6.2 with a numerical approach to represent thermal phenomena and biomass decomposition reactions during the pyrolysis process. The simulation results indicate that increasing temperature significantly affects the rate of heat transfer and the temperature distribution of coffee husk particles. At 600°C, heat transfer and temperature distribution are more uniform compared to 500°C, although heating at the particle core is not yet fully optimal. The pressure distribution shows a stable flow of pyrolysis gas from the bottom to the top of the reactor. In terms of products, increasing temperature leads to a reduction in biochar and bio-oil formation due to the occurrence of secondary reactions, while biogas production increases. The highest gas production is achieved at 700°C, indicating the most optimal condition for maximizing gas yield from fast pyrolysis. Therefore, single-particle-based CFD simulation can be used as an effective tool to understand pyrolysis mechanisms and optimize process parameters in a screw reactor.

This study aims to identify and minimize waste in the process of procuring Food & Beverage raw materials at Hotel PXY Jasa Bali using the Lean Inventory Management approach. Observations over one month showed that the total procurement cost reached 47% of the total revenue, exceeding the ideal limit of 35%. One of the main causes is the inefficient and lack of synchronization between divisions in the Rhapsody platform, which causes waste in the form of defects, delays, over-processing, and transportation. This study uses the Value Stream Mapping (VSM) method to map actual conditions and Process Activity Mapping (PAM) to identify the type of activity based on the waste category. In addition, root cause analysis is carried out using the Root Cause Analysis (RCA) approach. The mapping results showed that out of the total lead time of 598.44 minutes, only 278.49 minutes or 46.54% were value-added activities. This finding indicates that the procurement process is not yet efficient and needs optimization. Several recommendations were given to minimize waste, such as clearer division of tasks, improved communication with vendors, and the procurement of supporting facilities to reduce physical movement between divisions. The implementation of this lean service is expected to be able to increase the efficiency of the logistics process and reduce the company's overall operational costs.

Water is an essential need for all living things on Earth to support various vital biological processes. Without water, life cannot exist because of its role as a solvent, nutrient transport medium, and temperature regulator. Water in nature does come from various sources such as rivers, lakes, rain, and groundwater, which are not all clear because they are contaminated with particles or other substances, in contrast to mountain springs which are often purer. In this study, a water filtration system was created aimed at making turbid water purify to be suitable for use by assessing the NTU (Nephelometric Turbidity Unit) of turbid water due to suspended particles such as mud or sediment, thus producing clear water suitable for use for household or irrigation purposes. The use of two Siemens S7-1200 PLCs as controllers in the water filtration system is a reliable redundant approach to automate mechanisms such as pump, valve, and NTU sensor settings. PLC 1 is used for the filtration system and PLC 2 is used for the water distribution system. The water distribution process uses a DC pump that runs when it receives input from the water level sensor in the raw water tank and clean water tank. The water filtration process has three main stages: reading the water turbidity level using a turbidity sensor, regulating the water flow rate using a solenoid valve, and filtering the water using filter media. The system's operation can be monitored and controlled through a SCADA system. Both PLCs are connected using an OPC server for communication between the PLC and SCADA. The OPC server sends data from the PLC to the Wonderware InTouch application as the SCADA system. To monitor and control the SCADA system, users must log in to access the system.

In article 157A of Law Number 6 of 2023 that in the process of termination of employment, employers and permanent workers must carry out their respective obligations, employers can carry out suspension actions and still pay wages and other rights, but in reality employers rarely apply article 157A. The purpose of the research is to analyze the Implementation, Obstacles and Efforts on Workers' Rights in Wage Payment During the Termination of Employment Process at Palm Oil Company in Siak Regency. This type of research is Sociological legal research. In this research, three approaches are used, namely the legislative approach and the data source case approach using primary data and secondary data. The data collection technique used is primary data through interviews and questionnaires. The conclusion of this study is the legal protection of workers' rights during the termination of employment by the company through the settlement of industrial relations disputes in which there are various interpretations regarding the wage process. Article 157A of Law Number 6 of 2023 states that the responsibility of employers and workers remains valid until the industrial relations dispute settlement agency makes a decision. The implementation in the process of termination of employment is that workers are no longer allowed to work by the company but do not carry out suspension actions, but there are many companies that do not carry out things regulated by law. With the existence of multi-interpretation regulations on wages, the process provides uncertainty for workers, as well as in the interim decision submitted by the worker/plaintiff which is rejected by the judge which is clear that the worker can prove that the employer does not carry out his obligations as it should.
