The opportunities for developing grapes on an agribusiness and agroindustry scale in Indonesia are very high but have not been widely implemented. The aim of this research is to analyze the obstacles to the development of the current downstream grape supply chain. To develop the downstream grape supply chain, the first step is to identify the sub-elements that are part of the affected sector elements, the obstacles that occur and the programs needed. Identification of sub elements is carried out using ISM. Based on the results of the Interpretive Structural Modeling (ISM) analysis, the results showed that the obstacles to the downstreaming of the wine supply chain were that it had not paid attention to farmers who were the most important actors, had not designed a quality assurance system which was a program that should have been designed from the start of downstream planning and didn’t pay attention to the availability of materials. standard which is the main obstacle that has not been implemented so far. These three sub-elements can be integrated for institutional design to make downstream activities easier.

In the development of the industrial revolution 4.0, in carrying out production at small, medium, and large levels, there has been a fairly large and significant increase. Factors that influence the goal of successful production are not only about investment, capital, suppliers, machines, skills, and distributors but also one that must be observed is the layout planning and placement of factory facilities. PT. Eworx Indonesia is a company engaged in the processing industry, especially manufacturing in the metal processing sector. PT. Eworx Indonesia intends to relocate the production floor in order to increase production productivity. In this study, the proposed layout design on the new production floor was carried out using the SLP, Blocplan, and FLAP methods. The design is done by collecting direct observation data and interviews with the operator on duty. It was found that the initial layout had problems with operator movement that was not optimal and the placement of several machines and facilities that did not pay attention to material flow resulting in a slowdown in production time. Therefore, in order to get the best layout, a comparison is made on the results of the three alternative layouts with the smallest displacement distance comparison so that the production process will run more optimally. The best proposed layout is the systematic layout planning (SLP) method with the smallest material displacement distance of 147.4 meters and material handling costs Rp. 223,958 per day. Flexsim simulations show this layout can increase production output by 15%-34%.

The COVID-19 pandemic has had a significant impact on the Indonesian economy, particularly in the transportation and logistics sector. This sector has experienced fluctuations in financial performance triggered by the COVID-19 pandemic. However, after overcoming this challenging period, the Indonesian economy has shown positive trends. A leading logistics company, PT Logistik ABC, located in Jakarta, has a non-exclusive working agreement with a herbal medicine manufacturing company, PT XYZ. PT XYZ provides the required quantity of goods, but PT Logistik ABC is not obligated to fulfill the entire demand. The issue lies with PT Logistik ABC, as they transport goods from Jakarta to Semarang, but the fleet condition from Semarang to Jakarta is empty. With this situation, PT Logistik ABC aims for a higher gross profit by maximizing the available resources. Therefore, this study employs an optimization approach to optimize gross profit using non-linear programming. The optimal gross profit obtained is Rp150,893,000.00, representing 62% increase from the previous amount of Rp93,461,000.00.

This research builds upon the author's earlier work on the design of a cassava pulling tool. The aim is to develop a non-mechanical or minimally-powered tool that addresses farmer needs. The tool design incorporates Quality Function Deployment (QFD) to ensure user satisfaction. QFD is a method that integrates customer desires into technical requirements during the design phase, prior to production. Data analysis revealed key user desires: lightweight materials, affordability, the ability to pull multiple cassava stems simultaneously, durability, safety, and additional functionalities. House of Quality (HOQ) analysis identified the most crucial attribute (weight of importance: 30%) as the ability to pull multiple stems at once. This finding served as the primary basis for prototype development and technical characteristic definition. Subsequent prototype testing successfully uprooted cassava plants, demonstrating the tool's capability of pulling multiple stems in a single operation.
