Abstract

Logistics companies are very important in managing materials for smooth operations. In this company, which specializes in logistics through ocean shipping, faces risks when carrying out tasks such as lifting logistics goods in containers, moving oil, coal, and machine tools. To minimize the possibility of accidents, is necessary to identify, analyze, and manage potential hazards using the HIRARC method. Risk assessment shows variations in risk levels for different activities and control efforts. Hazard control is carried out through measures such as being exposed to embers that cause blisters, which can be prevented by controlling them using complete personal protective equipment, falling from stairs can be prevented by routine inspection of the condition of the stairs, triggering fires in the combustion chamber can be prevented by providing training to oil pump operators, bumping heads can be prevented by wearing safety helmets, and Being crushed by goods can be prevented by neat arrangement of goods.

Abstract

Indonesia is the second largest producer of palm oil in the world today after Malaysia. Since 2003, the amount of palm oil production in Indonesia has reached approximately 9.9 million tons per year. According to (BPS 2021), the area of oil palm land in North Sumatra reached 442 072.76 hectares. This research will purify used cooking oil using natural adsorbents by utilizing palm frond waste. Palm fronds are chopped into powder, then sifted with sizes of 50, 70 and 100 mesh after which they are weighed with weights of 1.5, 3 and 4.5 grams. Oil palm frond adsorbents with mass variations of 4.5 grams have the greatest adsorption power in reducing used cooking oil and the best adsorption kinetics based on the correlation coefficient is the pseudo second order equation.

Abstract

The statistics center in 2021 stated that North Sumatra is the second largest palm oil-producing province in Indonesia with a plantation area of 1,373.30 Ha. The use of cooking oil in Indonesia in 2021 was 18.4 million tons and increased by 6% from the previous year. This research utilizes palm fronds for the manufacture of adsorbents in cooking oil refining. The method used is carbonization with the help of pyrolysis. The carbon is chopped into powder and divided by variations of 1.5, 3, and 4.5 grams. Each gram is stirred using a shaker with speed variations of 50, 70, and 100 rpm. Turbidity is tested using a turbidimeter once every 20 minutes for 180 minutes. The results of the analysis showed that the best adsorbent weight in reducing used cooking oil was 4.5 grams with a turbidity level of 15.5 NTU and stirring of 100 rpm.

Abstract

Pekopen MSMEs produce banana chips that always strive to produce good products, but in fact they still find some products produced are not in accordance with standards. These problems can be solved using nP control maps, Ishikawa diagrams, and process capabilities, as well as calculations using minitab software. By using some of these methods, it is expected to find the factors that cause product defects. There are several variables to assess the defects of banana chip products, including shape, color, and size variables. The results of this study show the factors that cause defects in banana chip products, namely method factors caused by the manual banana chip cutting process, inaccurate selection of raw materials, manual frying process, and manual packaging process. In addition, it was found that the level of specifications and standards for process capabilities was not less than 95% and no more than 3% of the inability of MSMEs to produce banana chips in accordance with specifications and standards.

Abstract

Investment decisions are a complex process involving risk evaluation, market analysis, and investment return projections. In the decision-making process, investors sometimes show irrational behavior because they have cognitive limitations and previous investment experience so investors are exposed to overconfident behavior. This research used 178 samples consisting of investors who had investment experience of at least 1 year. The research carried out instrument testing and used the common method bias (CMB) testing procedure. The analytical method in the research uses simple linear regression. The results of testing the research hypothesis obtained positive and significant results of overconfidence bias towards irrational investment decisions The moderating role of sharia sharia considerations on the relationship between overconfidence bias and unsupported investment decisions. This research reveals that overconfidence can have a positive influence on irrational investment decision-making. Investors who tend to have excess confidence in their knowledge and skills in analyzing the market tend to make investment decisions that are more impulsive, less rational and sometimes ignore risks significantly. Future research is recommended to further investigate the mechanisms behind the relationship between overconfidence and irrational investment decision-making, as well as involving a wider sample to obtain stronger generalizations.

Abstract

The inspection train is specialized equipment used for examining railway tracks, transporting personnel, and carrying work equipment. The inspection train must be equipped with operational tools, monitoring equipment, and work comfort equipment. One of the comfort equipment is air circulation control, which should provide comfort to the personnel while working. Factors influencing the air temperature inside the inspection train include the number of passengers and duration of door opening. This research employs the Design of Experiment data processing method, with the data analyzed using a 2-factor factorial design experiment, with the assistance of Minitab software to understand the influence of the number of passengers and the duration of door opening-closing on temperature changes inside the inspection train. The result obtained from Minitab analysis indicate that the number of passengers has a significant influence on temperature changes inside the inspection train, accounting for 5.2% of the variation. On the other hand, the duration of door opening-closing does not have a significant effect on temperature changes. Additionally, the interaction between the number of passengers and the door open-close duration does not have a significant influence on temperature changes inside the PPI Madiun Inspection Train.

Abstract

Procurement is a company activity in obtaining goods according to the specifications they need and meeting the criteria in the form of qualifications, requirements and regulatory rules related to the procurement of goods and services. PT X is a company affiliated with a state-owned enterprise operating in the sugar cane agro-industry sector that produces sweet soy sauce as their downstream product. In this object, researchers found a problem that the production of sweet soy sauce at PT X could not meet the needs of consumer demand due to the limited capacity of the sweet soy sauce cooking machine. Therefore, PT X procures a sweet soy sauce cooking machine with a limited tender auction system. The selection of supplier I (PT KM) and supplier II PT (TSE) which is a soy sauce production cooking machine supplier was selected using the Analytical Hierarchy Process (AHP) and Taguchi Loss Function methods. The results obtained from this study obtained that supplier II (PT TSE) is the best supplier with synthesis results weight of 0.747 or has a percentage of 74.7 as well as the results of Taguchi Loss Function calculations where supplier II fulfills all types of quality loss functions on each price subcriteria, namely on the price of the smaller better machine with a weight of 0.1228, the cost of insurance for the larger better machine with a weight of -0.0920, and the shipping cost of the smaller better with a weight value of 0.0294.
