Abstract

The problem faced by PT Sari Kayu is that fluctuating production demand and high product variance make production inefficient. If the problem does not have a good factory layout, it affects material handling costs, material handling distances, and material handling time. For example, at PT Sari Kayu, there was a delay during a wrong project because the two projects were running simultaneously. The delay is due to the lack of resistance of the production floor to sudden high fluctuations in production demand. In addition, product variance is also a factor in the longer production process due to the different sequence of production processes and less supportive machine layouts. It is hoped that with the proposed layout, PT Sari Kayu will be able to face the fluctuating demand for production.

Abstract

Pong's Snack is an MSMEs originating from Ponggang Village that produces various types of snacks such as opak, rengginang, cassava chips, wajid, potato chips, taro chips, banana chips, Seroja, kicimpring, and cistik. MSMEs in Ponggang Village still use conventional methods, such as marketing products by entrusting them to stalls, can order in advance via telephone number and the product is delivered directly to the customer. Therefore, the author helps MSMEs to be better known to the wider community by entering the products produced by MSMEs into the Pareang Sate Restaurant and selling their products online through the Tokopedia application. To be able to market products online, it is necessary to take steps that can be used as guidelines in digital marketing activities aimed at the target market and known as AIDA (Awareness, Interest, Desire, and Action). The first step taken by the author so that Pong's Snack MSMEs products can be known to consumers is to build awareness of consumers by using the 7P product, price, place, promotion, people, process, and physical evidence approach. To increase interest in buying a product, a standing pouch is used an attractive label and packaging design.

Abstract

PT. Charoen Pokphand Indonesia Tbk. (Gorontalo) is still experiencing problems in managing fuel supply where the company often experiences a lack of inventory that hinders the production process. The company also experienced excess inventory, causing storage costs to rise. For this reason, companies need to exercise inventory control. One of the analytical tools that can be used to control inventory is the "Economic Order Quantity" (EOQ). From the calculation results, it was found that the optimal number of fuel supply purchases from palm oil shells using the EOQ method is 352 tons with a purchase frequency of 3 times in one period (1 year) so that the company can save fuel procurement costs. . The total inventory cost of raw materials with an EOQ of Rp. 32,845,640 while the cost incurred by the company without using EOQ amounted to Rp. 34,731,000. The savings that can be made by the company is Rp. 1,885,360 with a Reorder Point of 81.9 tonnes and a total safety stock of 241 tonnes.

Abstract

Corona virus or often called COVID-19 is a virus caused by SARS CoV 2, where the incident was uploaded in the world of health or we often call WHO. Even the World Health Organization (WHO) has declared that the corona virus outbreak is a Public Health Emergency of International Concern (PHEIC) or an international public health emergency. Not only has an impact on health, but this virus outbreak has also had a major impact in various sectors such as disrupting the country's economy, disrupting the education process and so on. This impact is caused by the very fast spread of the virus. Therefore, the author will analyze the level of accuracy in the covid-19 virus by using the certainty method model which aims to make it easier for local governments to monitor the spread of the COVID-19 virus and can determine future policies so that the spread is not more easily exposed to the community. this method will produce data analysis and diagnoses regarding identifying the covid-19 virus with results in the form of accuracy, namely someone is indicated as COVID-19 POSITIVE.

Abstract

Cibitung Hamlet, Ponggang Village is one of four partner villages of the Industrial Engineering Study Program of Atma Jaya University (UAJ) in community service activities. Continuing economic development for Ponggang Village, the community service team saw an opportunity in Cibitung Hamlet to plant water spinach as a selling product and increase vegetable consumption for the Ponggang Village community. To support the planting of water spinach, fertile soil, sunlight, and water are needed. Fertilization is really necessary to increase or maintain plant fertility by adding artificial or natural nutrients. The Community Service Team conducted a preliminary study on the effect of organic fertilizers, inorganic fertilizers, fertilizers from biogas dregs (bioslurry), and no fertilizers, using the soil in Cibitung Hamlet on the growth of water spinach. Based on the results of the study, fertilizers using biogas dregs provided heavy metal content values below the limit and also provided a fairly good level of water spinach growth compared to the treatment of organic fertilizers, inorganic fertilizers, and no fertilizers. The results of his study were socialised to the community of Cibitung Hamlet, Ponggang Village in the form of community service
