Polypropylene is the most widely used polymer material in the automotive industry due to its properties such as good rigidity, high melting point, chemical resistance, and easy processability. Polypropylene is usually added with a filler, namely bentonite, to make polypropylene which has better mechanical and thermal properties. The coupling agent is added to improve the adhesion of the matrix with the surface so that the composite component has better durability. To improve the ability of the filler material, bentonite is converted into nanoparticles. Bentonite nanoparticles are expected to have better mechanical, thermal, electrical, and optical properties than particles with micro or macro sizes due to their large surface area. Based on the description above, it is necessary to study the effect of using bentonite nanoparticles with a coupling agent in the form of Maleic Anhydride-g-PP (MAPP) on the tensile strength and thermal properties of polypropylene composites. The variables of this study are the composition variation (weight %) of polypropylene, coupling agent (MAPP), and bentonite nanoparticles of 100:0:0, 95:0:5, 90:5:5, 85:5:10, 92:3:5, and 87:3:10. The method used in this study uses a twin-screw extruder tool with a temperature of 190°C and then tested regarding its tensile strength and thermal properties. The results showed that the addition of nano-bentonite tends to cause an increase in the decomposition temperature of the sample but does not increase the tensile strength of the composite, so it only functions as a polymer composite filler. While based on Differential Scanning Calorimetry (DSC) testing, the enthalpy value decreases with increasing concentration of coupling agent.

PT. YZ is currently still not optimal in utilizing the resources it has (input) so that the results (output) produced are not in accordance with the target which results in a decrease in company productivity and so productivity measurements must be carried out in the company. Besides that, at PT. YZ has never conducted a thorough productivity measurement during the production process. Therefore, in this study, productivity measurements were carried out with the aim of knowing the results of measuring productivity levels at PT. YZ, to find out the factors causing a decrease in productivity levels and evaluate productivity against measurement results that have low productivity. The proper method for analyzing these problems is to use the Marvin E Mundel method to measure productivity and the Productivity Evaluation Tree (PET) method is used to evaluate productivity issues. In carrying out processing using this method, it is assisted by the Embarcadero-Dev C ++ Software. Based on the results of research using the Marvin E. Mundel method, it was found that company productivity had decreased, namely that in 2021 total productivity was 1.14 and in 2022 total productivity was 1.13. The cause of the decline in company productivity is that the labor factor is not clearly regulated for sanctions and rewards for the company; the raw material factor is the long distance of delivery from the raw material supplier to the production site; and the energy factor has not yet carried out accurate calculations regarding the use of electricity for the process. Production and machine factors have not yet established a machine maintenance schedule. The evaluation results using the Productivity Evaluation Tree (PET) method show that total productivity has increased; in 2022, total productivity was 1.13, and in 2023, total productivity was 1.15. To increase productivity, this was done by reducing input, namely the number of workers. By reducing the number of workers, productivity increases.
PT.目前，YZ 公司在利用其拥有的资源（投入）方面仍未达到最佳状态，因此产生的结果（产出）与目标不符，导致公司生产率下降，因此必须对公司的生产率进行测量。此外，PT.YZ 公司从未在生产过程中进行过彻底的生产率测量。因此，本研究进行了生产率测量，目的是了解 PT.YZ公司生产率水平的测量结果，找出导致生产率水平下降的因素，并根据生产率低下的测量结果对生产率进行评估。分析这些问题的正确方法是使用马文-E-蒙代尔（Marvin E Mundel）方法来测量生产率，并使用生产率评估树（PET）方法来评估生产率问题。在使用这种方法进行处理时，要借助 Embarcadero-Dev C ++ 软件。根据使用马文-E-蒙代尔方法的研究结果，发现公司的生产率有所下降，即 2021 年的总生产率为 1.14，2022 年的总生产率为 1.13。公司生产率下降的原因是，劳动要素对公司的处罚和奖励没有明确的规定；原材料要素是从原材料供应商到生产现场的长距离运输；能源要素尚未对工艺用电进行精确计算。生产和机器因素尚未制定机器维护计划。使用生产率评估树（PET）方法进行的评估结果显示，总生产率有所提高；2022 年，总生产率为 1.13，2023 年，总生产率为 1.15。要提高生产率，就要减少投入，即减少工人数量。通过减少工人数量，生产率得以提高。

Health service providers such as hospitals have a very diverse supply chain in quantity and type, one of which is medicine. Hospital Pharmacy Installation (IFRS) is one of the health support activity units responsible for planning, procurement, management, storage, distribution, use of drugs, equipment, and pharmaceutical services for medical devices related to the distribution of drugs used in hospitals. Pharmacy has several risks that need to be addressed to increase customer satisfaction. This study aims to determine the extent of the implementation of Supply Chain Risk Management, identify risks in supply chain activities, and obtain risk management strategies. In this study, the method used is the assessment of Supply Chain Risk Management and continued the evaluation of the drug chain in pharmaceutical installations with the House of Risk. It is divided into two stages, namely House of Risk Stage 1, which is used to decide the risk in each supply chain, and House of Risk Stage 2, to offers a decision-making strategy for each chosen decision. There are 20 risk events and 20 risk agents in the House of Risk stage 1, and 11 proposed risk management strategies in the House of Risk stage 2. Out of 20 risks identified in stage 1, 11 risks contributed to 80% highest risk, and the top three are drug shortage, inappropriate planning, and unclear doctor’s writing. In stage 2, the three most prioritized strategies are e-prescription implementation, clear signs for LASA drugs, and conducting supplier performance evaluation.

The production process is an activity to create or increase the function of a good or service by using existing factors such as human resources, machines, materials and money to make it more useful for human needs. PT XYZ is a cosmetic manufacturing services company that has been established for more than 15 years producing quality cosmetics, skincare and beauty soap. However, during the production process there were various problems, namely waste was found. The aim of this research is to identify waste and provide suggestions for improvements to PT XYZ's transparent bar soap production line. The method used in this research is Value Stream Mapping (VSM) by conducting interviews and direct observation as a data collection method. The results of the research that has been carried out are the discovery of waste in the form of transportation, waiting, and defects caused by various factors. These factors include human factors, methods, machines, processes and the environment. From the identification results, several recommendations for improvement were proposed, such as holding training on the use of sealing machines, implementing the 5R culture, routinely checking raw materials, optimizing the use of cutting machines, and routinely monitoring products and employee activities. After carrying out the improvement process, the production time was 2,581.36 minutes with a lead time of 26.29 minutes, compared to the initial condition, which was 4,102 minutes with a lead time of 39.89 minutes. Thus, it can be concluded that after carrying out the improvement process, it is hoped that the production process will run faster than before.

This research aims to determine the appropriate leadership style in the public sector transition period from implementing vernacular risk management to formal risk management or ERM. This leadership style also considers leadership factors, and implementing a risk culture has become the main factor in implementing ERM in various studies. The research method uses a descriptive qualitative approach, with a research strategy in the form of case studies. The data used is primary data and secondary data. Primary data is the results of interviews with 16 respondents who are parties who participate in managing risks at the ZYX ministry. Secondary data is all internal and external data related to MRPN. The general conclusion is that Agile leadership is needed so that ZYX Ministry can adapt to the VUCA era. Leaders with agility can guide their organizations to become faster, more adaptive, and more productive. Agile Governance is the key to responsive and proactive governance.
