The large market for cow's milk makes the order capacity for cow's milk high and will increase the milking process. In the production process, especially the milking process, people still manually use their hands, so fatigue often occurs, especially in people with more than 2 livestock. This causes the production process to be ineffective and the production results are also limited. Creating an automatic milking machine equipped with a milk can, a vacuum tube and a hose. Besides, a topology study will also be carried out based on the model of the machine. The three-unit component will affect the performance of the Milking Machine, especially the milk collector and milk can. Their size needs to be analyzed to get the optimum one. Optimization results for the topology of the milk collector bore diameter showed that the milk flow rate in the milk collector at a bore diameter of 9mm was 6,154 ltr/min, at a bore diameter of 14 mm was 26,566 ltr/min and at a bore diameter of 19mm was 66,128 ltr/min (conditions without being connected to hose). The shape of a milk can with a reduction of 30% from the initial weight, which is 3,358 kg to 2,350 kg, is owned by a milk can with the most optimal cone-dome tube shape. The difference in weight with the tube is generally 1,008 kg. The quantity flow when installed with a 2m long hose is 6,729 ltr/min

Warung Tegal is a small, lower-middle class restaurant in Indonesia. The name Warung Tegal, comes from Bahasa Indonesia, where "Warung" translates to "food stall" and Tegal refers to a city in Central Java. Warung Tegal, like many other small businesses, has been affected by the impact of the Covid-19 policies. In order to recover, Warung Tegal need to focused on improving supply chain management strategies especially for fish as one of the menus. This study aims to analyze supply chain management strategies in order to understand FSCM at Warung Tegal in the Administrative City of South Jakarta. The research method used was qualitative descriptive. The data was collected from ten respondents through structured interviews and observation. The sample for this study was the Warung Tegal managers in the Administrative City of South Jakarta. The results of the study showed that the fish at Warung Tegal is usually sourced from the nearest market, but the menu does not take into account the requests of the consumers and is never marketed through digital marketing due to the lack of knowledge in this field. The manager of Warung Tegal also stated that the restaurant's income has been reduced as a result of the Covid-19 policies. The study is limited by the time available for research and only covers the Administrative City of South Jakarta and not the entire DKI Jakarta area. Earlier study only identifies the influence of supply chain management strategies on the buying interest, with a positive result. While this study analyzes supply chain management strategies both before and after the enforcement of the Covid-19 policies.

The purpose of this research is to determine the key operational variables that impact productivity in PT BORNEO and identify optimal targets to improve productivity. A mixed methodology of qualitative and quantitative approaches, supported by process observation, was used to collect data. The study primarily uses existing quantitative data, but interviews may be conducted to capture constraints in the implementation plan process. GPS data also collected via an API to obtain information about truck movements, which can be divided into various activities to identify cycle time and analyze system performance. The study found that reducing loading time and minimizing random stoppages can significantly improve productivity, with average loading time being the most important factor. Stoppage before rest time and stoppage in loaded condition and at major prayer time had little impact on overall productivity. Future research could investigate the impact of other variables such as equipment maintenance and driver training on productivity.
