Abstract

Production management is responsible for making smart decisions regarding the most suitable production strategy for the future, focusing on reducing costs as efficiently as possible while increasing profit potential. UD Inti Jaya is a business engaged in building, namely the manufacture of tile from clay. UD. Inti Jaya has used various different methods of production planning and raw material inventory management. In order to improve the efficiency and effectiveness of production planning, the company has implemented several methods and techniques. First, the company uses the method of forecasting product demand for future periods. The results of this forecasting are used for production planning using aggregate planning methods, especially the Trial-and-Error method. To determine raw material needs, here the company uses the Economic Order Quantity (EOQ) method to calculate raw material inventory needs with the aim of minimizing inventory costs. Results from the use of the EOQ method shows that the inventory cost of raw materials produced is smaller compared to the previous inventory policy used by the company. This indicates that the EOQ method provides better efficiency in raw material inventory management, reduces inventory costs and allows companies to have appropriate safety stock and reorder more effectively. Thus, the conclusion that can be drawn is that the application of the EOQ method in raw material inventory management provides better results, with lower inventory costs compared to previous policies implemented by the company. This illustrates that using the EOQ method can help companies in more efficient and effective inventory management.

Abstract

Kampung lumpia, located on Jalan Ngaglik, Surabaya graveyard, is a home industry (IRT) managed by Mr. Kasmono as the owner. This business was initiated in 2009. The number of employees employed on the production floor is 4 people, and 3 employees to sell spring rolls in groups. The problem for SMEs is that minimal capital makes the owner not replace the pans and stoves for making spring roll skins and frying spring rolls. The frying pan and stove have been used for 10 years since this business was founded so that it is black and charred and the addition of 1 new rombong unit to increase market share in other sales locations. In terms of marketing, it is still done offline using a group, the owner wants to try marketing online, for example advertising to receive orders on online social media. In terms of selling price, the spring rolls and risoles that are produced are sold at a price of Rp. 1,500.00 per seed. The owner does not know the bookkeeping and calculation of the cost of production for the spring rolls and risoles that he sells, so training on the calculation of the cost of production is necessary.

Abstract

One of the leading horticultural commodities cultivated by farmers is chili. However, chili farmers often experience problems monitoring soil moisture levels and environmental air temperature. In this case, it can affect the growth of chili plants, which impacts crop failure. Therefore, to overcome these problems, this research develops Mamdani fuzzy logic to build an intelligent system that can automatically monitor and water chili plants. In this research, the impact of the use of sensors and system impact treatment on chili plants will be tested and compared with plants that do not use the system. The results of this study show that the smart monitoring and watering system can function properly and maximize the condition of the plant media compared to those that do not use the system. The system can control soil moisture levels with an average error of 3.73% and air temperature with an average error of 1.03%. The results of the system by comparing plants that do not use the system combined with greenhouses can protect plants from extreme weather such as heat, rain, pests, and lack of wild plant growth so that plants look lush, lush, and grow quickly to minimize farmer crop failure. It is easier for farmers to monitor using the Blynk IoT application.

Abstract

This study aims to improve operational efficiency and financial management at Toko Pink 31 Surabaya by integrating two key components: store layout redesign and the development of a MySQL-based accounting system. The research uses a combination of qualitative and quantitative approaches through observations, interviews, system design, and simulations. The redesigned layout was developed using the Systematic Layout Planning (SLP) method and simulated via AnyLogic software to evaluate customer flow and service bottlenecks. The results showed significant improvements in space utilization, reduced customer congestion, and enhanced overall shopping experience. In parallel, the accounting system was developed using MySQL to automate and structure financial transactions. The system includes modules for product input, sales, purchasing, cost of goods manufactured (COGM) reporting, and daily financial summaries. The implementation of this digital accounting system reduced manual errors, streamlined transaction processing, and provided real-time access to financial data. The integration of both layout optimization and digital accounting demonstrates a comprehensive transformation model for SMEs, particularly in the retail sector. The findings emphasize that combining spatial efficiency and financial digitalization can significantly improve business performance, supporting broader efforts to digitalize micro and small enterprises in Indonesia.

Abstract

LOVETT scale is a common parameter used by the doctor or therapist to determine the muscle strength of the patient’s hands, especially patients with post-stroke. As a result of previous work of our group, a sensory glove for monitoring finger muscle therapy for post-stroke people with the name of Electronic Therapy Gloves (ETG) was proposed. With the flex sensor that embedded to the gloves we can measure the LOVETT scale of the post-stroke people. This sensory glove can help the patient doing their rehabilitation fast so that they don’t have to go to the hospital every week to check up their progress. In this work, we combine the data of sensory glove and the MYO armband for LOVETT scaling that has never been done before. The output of the Electronic Therapy Gloves can be optimized by 25%. All the LOVETT grade can be identify by the gloves, then it can help the doctor monitor the patient’s rehabilitation just by looking the patient’s record data with ETG.Keyword: LOVETT scale, flex sensor, MYO armband, post-stroke, rehabilitation.
