Abstract

In industry, manual lifting activities certainly involve muscles and generate risks if done improperly. There are problems in the form of complaints from industrial workers on manual lifting activities that are carried out in a less ergonomic manner. This study aims to determine the effect of lifting factor variables on the resulting level of muscle activation. In this case, three factors are used, namely the lifting method factor, the horizontal distance factor, and the vertical distance factor, each of which has two factor levels to produce eight combinations of lifting factors. Randomization was carried out on research subjects totalling 10 people. Previous research that has been done manually is by calculating the pulse resulting from a lifting activity according to a specified frequency. In this study, monitoring of muscle activity was carried out automatically using an instrument called Electromyography (EMG) at three points of the hand muscles, namely the biceps brachii muscle, triceps brachii muscle, and brachioradialis muscle. The results of this study indicate the best combination based on the value of muscle activation on the biceps brachii muscle, triceps brachii muscle, and brachioradialis muscle which respectively include combination 2 (M1-H2-V1) with a significance value of 0.002, combination 6 (M2-H2 -V1) with a significance value of 0.000 and combination 2 (M1-H2-V1) with a significance value of 0.013. The resulting combination of the best lifting factors can be used as a reference and recommendations for the ideal lifting posture and conditions for workers in minimizing possible injuries

Abstract

The Sumbagut Gas Engine Power Plant (PLTMG) operating in Lhokseumawe City, Aceh Province, recorded 19 minor workplace accidents during 2024. In response to this condition, this study aims to identify the risk factors and main causes of workplace accidents in order to develop effective prevention recommendations. This study uses two integrated risk analysis methods. Failure Mode and Effect Analysis (FMEA) is applied to assess and prioritize the level of occupational safety and health (OHS) risks in operational activities. The results of the FMEA analysis indicate that fingers caught in a press machine are the highest risk with a Risk Priority Number (RPN) of 252. Despite having a lower frequency, electrocution incidents are also identified as a critical risk due to their very high potential for fatality. Furthermore, Fault Tree Analysis (FTA) is used to dissect these highest risks, successfully identifying seven (7) basic events that are the root causes of accidents. These causal factors include human error (lack of focus), technical failure (sensors or machine hydraulics), and administrative failure (ignored LOTO procedures). Based on the FMEA and FTA findings, this study presents strategic recommendations to the management of the Sumbagut Gas Processing Plant (GPP) to minimize and prevent future accidents.   Keywords: FMEA, FTA, Occupational Safety and Health

Abstract

In general, a tumor is an abnormal tissue growth in the body that occurs due to uncontrolled cell division. Tumors can be benign (non-cancerous) or malignant (cancerous). Benign tumors tend to grow locally without spreading to other tissues, while malignant tumors can invade surrounding tissues and spread to other parts of the body through the bloodstream. A brain tumor is a mass or growth of abnormal tissue in or around the brain. Specifically, brain tumors can be primary (originating from the brain cells themselves or surrounding tissues, such as the meninges, pituitary gland, or cranial nerves) or secondary (metastasis from cancer originating from other parts of the body). The main problem today is that brain tumors have many types, therefore research on the classification of brain tumor types is very valuable today. In order to improve accuracy and also speed up the diagnosis process. The results of this study, brain tumor image data classification has been carried out using the CNN Algorithm method with the CRISP-DM data mining technique. The dataset consists of 3,554 datasets, but from the results of testing this algorithm has good performance with an accuracy of 98% with Evaluation and validation using the Confusion Matrix test parameters. and successfully classified human brains affected by tumors and those not affected by tumors, in addition to being able to classify 3 different types of tumors, namely glioma, meningioma, and pituitary.

Abstract

This paper presents a preliminary result of anthropometric data of 30 males Indonesian industry workers. For this preliminary results, 16 dimensions in the standing posture were presented. For each dimension, the summary of mean, SD and percentile (5 and 95) were calcaluted which are useful as the basis for the design of products, machines and equipments. The data in this study were compared with those from previous studies i.e Norwegia, Nigeria and India. From data comparisons, Indonesian workers are shorter than those of other nationalities from Norwegia and Nigeria. Meanwhile, anthropometric characteristics of Indonesian workers were found to be similar with India workers. As for application, anthropometric data could be used as the basis to determine the proper dimensions of equipments and machines to be used by workers. Furthermore, the results could become a benchmark for other countries targeting products and machinery for Indonesia market.

Abstract

Abstract The research aims to determine the influence of parental interpersonal communication on adolescent behavior in Dusun Tengah, Tlonto Ares Village, Pamekasan. The research employed a quantitative method through a regression test approach. Data were collected from 56 adolescents through the distribution of questionnaires. Hypothesis testing was conducted using the t-test. The research findings indicate that the correlation coefficient of 0.270 suggests a weak relationship between parental interpersonal communication and adolescent behavior. Hypothesis analysis using the t-test reveals a calculated t-value of 2.06, exceeding the critical t-value of 1.68. Therefore, the proposed hypothesis is accepted based on the criterion that if the calculated t-value is greater than the critical t-value, the hypothesis is accepted. The calculation results show that parental interpersonal communication has a 7.29% influence on adolescent behavior. Keywords: Communication, Parents, Interpersonal, Adolescents

Abstract

The adoption of electric motorcycles in Indonesia has seen rapid growth, driven by the push toward a sustainable energy transition. However, battery safety remains a significant concern, particularly with Lithium-ion and Sealed Lead Acid (SLA) battery types. This study aims to analyze the failure mechanisms behind a fire incident on the passenger motor vessel (KMP) Tranship 1, which was allegedly triggered by a Lithium-ion battery from an electric motorcycle lacking an adequate protection system. The analysis employs Fishbone Diagrams and Fault Tree Analysis (FTA), drawing on data from field case studies, evaluations of protection systems in locally manufactured electric motorcycles, and a review of relevant technical literature. The root cause analysis using the Fishbone Diagram identifies several contributing factors to fire risk, including improper usage and charging practices, inadequate transportation methods, extreme environmental conditions, and equipment failure. Findings from the Fault Tree Analysis highlight the critical role of safety components such as fuses, circuit breakers, and ventilation systems in preventing battery-related fires or explosions in electric vehicles. Based on these findings, the study recommends the implementation of multilayered protection systems, the use of standardized chargers, and the development of national regulations aligned with international safety standards. The incorporation of a Battery Management System (BMS) is also strongly recommended to enhance battery safety and reliability.
