Abstract

Internet of Things (IoT) is a concept that utilizes internet network connectivity for a unified system communication. Analysis conducted on the keyword "Internet of Things" by using Google Trends shows trends up from mid 2013 to 2020. IoT will be a part of human culture which is implemented in all sectors of life. The corona virus pandemic is like a blessing in disguise in terms of the adoption and intervention of technology in all settings of human life. This is because during the Covid-19 pandemic, technology was present to be a solution and provide efficiency. This paper was prepared with the aim of completing a study of the application and adoption of information technology, specifically the field of the Internet of Things (IoT) in adaptation to New Normal life. To achieve the goal, this paper is divided into 3 parts, namely the IoT concept and vision section, the existing IoT implementation section based on the physical setting or place and the IoT solution section for New Normal adaptation after the co-19 pandemic in Indonesia. Based on the analysis and discussion, it can be concluded that experts and government are able to react quickly and appropriately in implementing technology (especially IoT) in Indonesia. However, it is still ineffectiveness and inefficiency, because each government unit’s builds its own system. Next, Indonesian government needs to think about and do is to integrate the system. So, it will be able to produce an integrated information that can be used by all elements of operations in all government unit’s that need it.

Abstract

The operator's work posture in production activities is very important to note. Ergonomic work posture will support work productivity. In UKM Las XYZ there are three work postures adopted by the welding operator namely standing bent, sitting on a short chair, and squatting. Welding is the job that causes the highest muscle complaints compared to other jobs in this UKM. The purpose of this study was to assess the risk of work posture adopted by welding operators. The assessment method uses the Rappid User Limb Assessment (RULA) and the Nordic Body Map. The results showed that the final score of the work posture bent has a score of 7, which means that this work posture needs to be investigated and implemented corrective actions. Work postures sitting in short chair and squatting produce a score of 6, which means that this work posture needs further investigation and immediate improvement. Measurement of muscle complaints showed that the part of the body that was experiencing the most pain was back and waist, with an average NBM score of 4 (very sick). This is caused by static or repetitive high frequency work postures adopted by the welding operator.

Abstract

Good equipment and product design are meaningless if there is no good layout planning. Problems that are owned by PT. Pilar Kekar Plasindo occurs in the production of small polyethylene. This is because small polyethylene production has large material total transfer distance. Small polyethylene problems, namely the distance between stations, cross-movement, backtracking, and the broken machine that is still placed in the production section. This makes the material handling costs and distances become large. So this research aims to produce a layout design of production facilities that can minimize the distance and cost of material movement. The method used is Systematic Layout Planning (SLP). Three alternative designs were compared, and the second proposed facility layout was chosen because it was able to reduce the total cost of material transfer by 68.3% and reduce the distance of material transfer by 59.6% from the initial facility layout.

Abstract

Lamongan Regency is the district with the highest broiler population in East Java in 2017-2018. The business opportunity in the field of broiler breeding is a business that is considered promising, maintenance cycles that only take about 35 days make farmers do not have to wait a long time to enjoy the results, especially since they have developed livestock with a core-plasma pattern. With a mutualism relationship where many breeders have limited capital, while partner companies also need a place to raise broilers that are not only focused on one area, a pattern of core-plasma partnerships has developed between the company and breeders. This study analyzes the economic side of animal husbandry business with a core-plasma partnership pattern with PT. CA, Lamongan Unit as a case study. Breeder-01 with a concrete cage and other wood and bamboo materials, has an investment of Rp. 450,000,000 (capacity of 14,000 broilers) is estimated to be 30 years old, based on net income in the last cycle of Rp. 25,160,000 and the 3% interest rate yields an NPV of Rp. 2,826,618,448, ROR value of 28.54%, Payback Period of 2.28 years. Whereas Breeder-02 with a wooden cage and other materials made of bamboo, has an investment of Rp. 250,000,000 (12,000 capacity) estimated to be 15 years old, based on net income in the last cycle of Rp. 21,830,000 and an interest rate of 3% resulting in an NPV of Rp. 1,497,984,299, ROR value of 33.47%, Payback Period 1.14 years. The results of the sensitivity analysis can also be concluded that investment in broiler breeding business in nucleus-plasma partnership pattern is feasible.

Abstract

Every year the use of plastic is always increasing. This causes plastic pollution everywhere. In order to decrease the plastic pollution, a recycling system is needed. Currently, several groups of people have created Ecobrick. Ecobrick is a waste recycling system that utilizes PET (Polyethylene Therepthalate) bottles filled with plastic scraps. To facilitate the cutting, a plastic chopper was created. This tool is designed with a chopper blade unit driven by a single phase induction motor. For transmission between motors to the blades used gears and chains. This tool is also equipped with an ultrasonic sensor and Arduino as a control. If the sensor detects that the plastic is inserted, the sensor will send data to be processed by Arduino, so the relay will activate the motor for 20 seconds, until the plastic is completely chopped. In order to know how long for all one plastic chopped, several experiments have been carried out. For power supply, each circuit uses two output adapters of 5 VDC and 9 VDC.

Abstract

Credit is crucial in financial institutions that affects the growth and development of these institutions. Weak supervision and management in the process of extending credit to customers can lead to high non-performing loans. This problem occured in one of the financial institutions that provides credit to customers, namely BMT X. Data for 2019 showed that there were 600 applications for multipurpose loans. Of these, only about 76% showed good collectability. The condition of credit collectability that is not optimal causes BMT X to spend more to collect installments that must be paid by the debtor directly. This bad credit causes losses to the financial institution. Thus, in providing credit, BMT X must be smart in assessing customer’ feasibility. The purpose of this research is to design credit policies in order to minimize the prediction errors of customers with bad credit category. The technique used in this research is classification data mining with the J.48 algorithm. To measure the effectiveness of an attribute in classifying a data sample set, it is necessary to select the attribute that has the greatest information gain which will be placed at the root node. This research produces six rules with an accuracy level of 80,2% so as it can be used by BMT X to search customer’s feasibility to gain credit. Keywords: Algorithm J.48, data mining, decision tree, credit risk

Abstract

PT XYZ is a company of a motorcycle component and equipment industry group. PT XYZ produces motor brake brackets which will be sent to HONDA and YAMAHA. This study aims to evaluate the work posture of workers at the bending station with the Rapid Entire Body Assessment (REBA) method and propose an improvement to minimize the risk of injury due to fatigue. In the bending process, there are 3 main activities, namely: object retrieval, object installation, and bending process. The results of calculation with the REBA method before improvement showed a high level of risk from each activity, namely a score of 8 for the first activity, a score of 5 for the second activity, and a score of 7 for the third activity. After the improvement, a lower average score is obtained, which is equal to 3, which includes a low-risk level of risk. Improvement of work posture is done by designing work aids in the form of work desks and work chairs Work tools that have been made can help workers to help improve their work posture in carrying out work activities, so as to minimize the risk of injury.
