Dunia pendidikan di Indonesia saat ini telah memasuki Kurikulum Merdeka, begitu juga dengan Sekolah Menengah Atas. Kurikulum Merdeka dinilai lebih sederhana dan fleksibel sehingga membuat siswa lebih aktif. Jenis-jenis aktivitas yang ada di dalam kurikulum ini lebih relevan dan banyak memberikan ruang untuk tugas berbasis proyek. Namun munculnya Kurikulum Merdeka ini menimbulkan permasalahan yaitu belum siapnya sekolah mengimplementasikan Kurikulum Merdeka khususnya dari segi mata pelajaran dan sumber daya. Begitu juga terjadi pada SMA IGNATIUS SLAMET RIYADI, Resinda Karawang. Sekolah sangat membutuhkan kerja sama dengan Universitas dari segi keilmuan dan juga sumber daya. Dengan perencanaan Kurikulum Merdeka yang baik dengan didukung mata pelajaran berbasis proyek yang menarik minat siswa tentunya dapat meningkatkan kompetensi siswa SMA IGNATIUS SLAMET RIYADI dan menarik perhatian orang tua siswa SMP untuk menyekolahkan anaknya di SMA IGNATIUS SLAMET RIYADI, Karawang. Oleh karena itu, Program Studi Teknik Industri Universitas Katolik Parahyangan menjalin kerja sama untuk menghasilkan mata pelajaran berbasis proyek, khususnya yang berhubungan dengan keilmuan Teknik Industri.

The COVID-19 pandemic has had a significant impact on a variety of sectors, including the furniture manufacturing industry. The industry is undergoing drastic demand changes, complicating adjustment efforts during the pandemic. Additional human resources (HRM) is becoming a more complex challenge due to strict health protocols and the necessary vaccination efforts. In this context, increased availability of capacity has become critical, but an appropriate approach has not been revealed in the literature. As for the in-depth literature study, it covers various methods of increasing production capacity, such as adding human resources, machines, shift work systems, overtime, and subcontractors. The research focuses on a new way to multi-skill by using the skill matrix as an innovative method to increase the availability of capacity at PT X, a furniture manufacturing company. Using Rough Cut Capacity Planning (RCCP), the study describes current production capacity, analyzes the impact of post-COVID demand shifts, and evaluates the effectiveness of multi-skill application with a skill matrix in improving production flexibility and responsiveness. The research findings provide valuable insights for furniture companies and related sectors in dealing with post-COVID dynamics, as well as providing the basis for developing more adaptive and sustainable capacity planning strategies.

The Fashion industry in Indonesia is one of the attractive industrial sectors for the creative economy sub-sector. Based on Statistics Indonesia, the GDP at constant prices of the textile and apparel industry amounted to 34.58 Trillion in the second quarter of 2023. However, clothing sales in physical stores have decreased due to online sales. Furthermore, in physical store sales, the dressing room is limited, the clothes being tried on are unhygienic and there are restrictions on the number of trying on clothes. So, it is necessary to design a clothing sizing tool that can determine the size of clothes, maintain hygiene and reduce queuing time when trying on clothes. The design of this tool begins with conducting interviews and identifying the necessary needs. After identifying the necessary needs, proceed with designing an affinity diagram to group needs that have similarities and determine the level of importance. The results of this determination will be designed into tool specifications using the Need-metric matrix and become the basis for developing tool concepts. From these results, a prototype was designed using Arduino, ultrasonic sensor and LCD display. Testing for the tool will pay attention to the performance results of measurement accuracy and usability testing. For the usability testing method, the SUS (System Usability Scale) method is used. From the results of the study, it was found that the performance value of measurement accuracy was 75.76% and the usability testing score was obtained 68. The performance value of measurement accuracy and usability testing still needs to be improved with proposals in the form of clothing requirements during measurement and the use of more automated tools to make it easier to use.

Indonesia is an archipelagic country rich in biodiversity, including various types of plants that provide important natural resources for the people's basic and economic needs. One of these resources is Hasil Hutan Bukan Kayu (HHBK), such as brown sugar, which is produced from palm sap. The simple and basic palm sap processing method inspired this research to design processing tools that can improve product quality and efficiency for palm sap farmers in Kiarajangkung Village, Tasikmalaya Regency. The product design process began by conducting interviews to identify the farmers' needs. It was found that farmers needed three tools: a furnace for boiling palm sap, a pourer, and a palm sap mold. Specifications for these three processing tools were sought to meet the farmers needs using the House of Quality (HOQ) method. The next stage was concept generation, where six concepts were created for each of the three processing tools. Each concept was tested, and to narrow down the options, two concepts were chosen for the boiling furnace, three for the pourer, and three for the palm sap mold. From these, the best concept was selected and developed into a prototype. The processing tool prototype was designed using Solidworks software before being tested in real conditions. Next, a physical prototype was made, which was later tested by sap farmers. The prototype was tested using the functionality testing method. From the results of the prototype trials, it was found that the processing tool prototype successfully met several success indicators, with some refinements needed for the tools.

Transportation is one thing that is very important and is the highest cost in the supply chain. One way to reduce these costs is to optimize vehicle routes. The Multiple Traveling Salesman Problem (MTSP) and Capacitated Vehicle Routing Problem (CVRP) are models that have been extensively researched to optimize vehicle routes. In its development based on actual events in the real world, some priorities must be visited first in optimizing vehicle routes. Several studies on MTSP and CVRP models have been conducted with exact solutions and algorithms. In a real case in the Jakarta City Street Lighting Section, the problem of determining the route in three shifts is a crucial problem that must be resolved to increase worker productivity to improve services. Services in MCB (Miniature Circuit Breaker) installation and maintenance activities for general street lights and priority is given to light points that require replacement. Because, in this case, the delivery capacity is not taken into account, the priority of the lights visited is random, and the number of street light points is enormous, in this study, we use the MTSP method with priority and solve by a genetic algorithm assisted by the nearest neighbor algorithm. From the resolution of this problem, it was found that the travel time reduction was 32 % for shift 1, 24 % for shift 2, and 23 % for shift 3. Of course, this time reduction will impact worker productivity so that MCB installation can be done faster for all lights and replace a dead lamp.
