Abstract

As time goes by, more and more new factories appear producing different products. The manufacturing industry is related to tools that support the creation of a corn and grain processing process. PT. Seger Agro Nusantara is a company processing agricultural products such as rice and corn. One of the tools used at PT. Seger Agro Nusantara (SAN) is a forklift to help reduce worker energy in lifting and moving goods. The problem that often occurs with forklifts is the hydraulics. Hydraulics are the main part of a forklift which functions to move, lift and move goods from one place to another. The advantages and disadvantages of hydraulics are that they can transfer large amounts of power using only relatively small components, operate smoothly, do not cause noise or unimportant vibrations in the machine, can be rotated in the reverse direction (reversible), make it easy to move heavy materials in one lift. , or moving goods up to tons in weight. And the service life is quite long, so you can save on the cost of buying new equipment. Meanwhile, the disadvantage is that it requires intensive and regular maintenance. One method that can be used to find the root cause of a problem is a fishbone diagram. Because the fishbone diagram already knows the problem but doesn't know the cause.

Abstract

This study aims to develop an automated warehouse storage system using Factory I/O and Siemens S7-1200 PLC. This research was conducted at the Control and Automation Laboratory of the ATI Makassar Polytechnic from July to September 2023. The research method used is quantitative deductive with an experimental approach, including the steps of literature study, system requirements analysis, state diagram design, and system testing through virtual simulation. The algorithm used is a state diagram algorithm consisting of ten states, namely: standby mode, entry to loader, fork left, lift up, fork middle, target position, fork right, lift down, fork middle, and home position. The results of the study showed that the state diagram algorithm was successfully converted into 14 networks (RUNG) in the PLC ladder, consisting of one RUNG for Flowchart (Indicator RUN), ten RUNG for state diagrams, and three RUNG for output devices (Fork Left, Fork Right, and Lift). The automated warehouse storage system successfully automates the process of storing cargo in the form of boxes and pallets from the first rack to the 54th rack automatically. This study shows that the automated warehouse storage system can run according to the planned design and provide significant contributions to the DCS and SCADA practicum at the ATI Makassar Polytechnic.

Abstract

CV FSA is a company engaged in the printing sector. The main printing produced in this company is labels for various types of vegetables. A production activity needs to be planned well. In the process of producing labels, the production planning carried out by the company has not been effective because there are still labels that have not reached the production quantity, namely 33369 sweet mustard labels. This can reduce consumer satisfaction with the company. Therefore, there needs to be effective label production planning in the future. To estimate the number of future order requests, it can be done using the forecasting method. In this study, the forecasting method used is Additive Decomposition. This study aims to plan the production of sweet mustard labels from November 2023 to October 2024. The company only produces labels when there are orders from customers or make to order, so the production planning method that can be used is the chase strategy. The calculation results using the chase strategy method obtained the number of sweet mustard greens label production during regular hours in November 2023 to October 2024 were 9037, 9626, 9757, 9350, 9735, 8681, 9970, 9361, 10057, 8788, 9391, 9661 pcs with the largest number of workers needed being 5 people.

Abstract

Acceleration of the process in product design is very important today. Thus, the time the product reaches the consumer is faster. The process of preparing and testing cartridges often takes time and resources, resulting in production delays and potentially affecting customer satisfaction and also wasting water resources used for testing. Product testing serves to validate product quality whether it is in accordance with specifications. This study was conducted to determine the causes and corrective actions for the length of the testing process carried out by the R&D team. The method used in this research process is Seven Tools. With additional calculations of NGT and 5W1H. From the analysis of the results obtained, the most dominant problem is the length of the test preparation process for the cartridge mechanism with a time value of 1980 minutes with a percentage of 70.7%. The most dominant problems include the fixed jig design so that it cannot be adjusted (NGT value 30) and the long dandori time (NGT value 25). The corrective actions that need to be taken for the 2 dominant causes of the problem are to repair the jig that originally could not be adjusted or set to make or repair a jig that can be set or adjusted. The results of this study are expected to be a future reference in the design process of jigs or testing process aids so that they are easy to use.

Abstract

The process of installing clips and wiring on the dump truck assembly line with an uncomfortable working posture of the operator, so that complaints due to fatigue often occur. This is because at the time of installation the part the operator has to bend because it is blocked by the battery. This study aims to assess the operator's work posture during the process of installing the clips and wiring, so that the risks obtained due to fatigue due to work can be known. The method used in this study is the Rapid Upper Limb Assessment (RULA) method. This method begins by distributing the Nordic Body Map (NBM) questionnaire to find out which parts of the body feel pain and fatigue. Based on the measurement results, the angle of the upper arm is 450 – 900 with a score value = 3, the lower arm is formed with an angle of 00 – 600 with a score = 2, the wrist part forms an angle of >150 with a score = 2. The results of the RULA table assessment based on the angles formed for each section, namely part A score=7, part B score 11, and part C score as end=7 are included in the high risk. Recommendations that can be given for high risk are observation and application of remedies.

Abstract

The concept of halal logistics is getting more attention, especially in the field of distribution and transportation, in line with the increasing demand for halal products in the global market. This study aims to determine the development of the implementation of halal logistics in courier companies in Indonesia using the method of review and literature study. Currently, there are technologies such as the Internet of Things (IoT) and blockchain to help in halal logistics tracking and traceability systems, which can open up opportunities for further innovation in the logistics sector. In Indonesia, there is only one courier company that already has halal certification. However, in its implementation, of course, there are still many problems and challenges faced. One of the biggest challenges is the lack of understanding of halal logistics concepts and standards among courier companies and industry players. Many courier companies do not fully understand halal requirements, both in terms of storage, transportation, and product handling. With a commitment to meeting halal standards and using the right technology, courier companies in Indonesia have a great opportunity to play a more strategic role in supporting halal supply chains domestically and around the world.
