Abstract

A good work environment will increase job satisfaction, morale, and employee performance. The company has 5 production stations, namely Printing and Can Making, Blow Moulding, Shortening and Margarine, Filling, and the last is Finished Product Store. Based on observations at the Printing and Can Making, Blow Moulding, Shortening and Margarine, Filling, and Finished Product Store stations, there are unclean and untidy conditions at the Blow Moulding station. Fishbone diagrams are also used to determine the root causes of work environment problems. The cause of the Blow Moulding station being unclean and untidy is the human factor and the method applied. Based on the problems obtained  the 5S method is used to arrangement and maintenance of the workplace which was developed through intensive efforts in the work environment of the blow moulding station. When everything has its place and there is the right position, then the 5S program will serve to provide a clear picture of a good workplace.

Abstract

Occupational Safety and Health is the primary means of prevention of occupational accidents, disabilities and deaths so that the consequences of occupational accidents from potential hazards can be prevented. Companies need to develop risk management based on hazard identification and risk assessment compiled in occupational safety and health programs. Occupational health and safety risk management is an effort of hazard management which potentially pose a risk to safety and health to prevent unwanted accident. The data collected in this research is primary data and secondary data. Primary data obtained through direct observation on the floor processing RSS (Ribbed Smoke Sheet) at PT. PQR is useful to observe the potential hazards of work contained in the work area. While the secondary data taken in this study is historical data. The result of determining the risk value for each hazard source contained in PT. PQR is classified by rankings marked with the code E (extreme risk), H (high risk), M (moderate risk), and L (low risk). This is obtained by comparing the severity and probability values of each process / activity. Of the 28 activities, there are 7 activities included in the category of high risk. Process / activity that belonged to high risk is necessary to control to minimize or even eliminate the existing risks. control measures that can be performed on a high risk process / activity is to use a complete Personal Protective Equipment (APD), MSDS, using warning signs, using ladders in sheet sheets, with ergonomic work posture.Factors causing potential work hazards are workers who perform activities of inadvertent, high temperatures, and negligence of workers in using PPE. These control measures are expected to reduce and even eliminate the risk of the process / activity classified as high risk so that the number of workplace accidents can be reduced.

Abstract

This paper aims to investigate and analyze some previous literature relevant to the Design for Manufacture and Assembly and Design for Safety methods in international journals. An extensive review and analysis of the body of literature was conducted to discuss the findings in a few chosen papers pertaining to the application of both methods, using a survey based on descriptive and qualitative surveys published in international journals with publication period limitations from 2011 to 2023 published in proceedings and electronic journals in English. So far, there has never been any research or literature review that discusses the Integration of Design for Manufacture and Assembly with Design for Safety.

Abstract

Urban farming is carried out to overcome limited land and increase family food security. Cultivating vegetable crops and raising fish are solutions for urban agriculture. The method for implementing International Community Service (PkMI) was implemented in Medan and Penang, Malaysia in June 2024 at the Griya Nusa Tiga Complex Blok B-29 Medan through: a). Socialization and Focus Group Discussion (FGD) regarding urban farming education in residential environments ; b). Hydroponic and Aquaponic training and practice (budikdamber); c). Entrepreneurship training and practice for partners; d). Mentoring and monitoring. PkMI results show ed an increase in the knowledge and skills of partners (20 residents of the Griya Nusa Tiga Complex) in understanding the definition, benefits and implementation of Urban Farming; the growth of the entrepreneurial spirit of residents for independent and sustainable aquaponic cultivation; and able to meet dual protein needs (vegetables and fish); processing budikdamber products appropriately.

Abstract

Penelitian ini dilatarbelakangi oleh fluktuasi dalam pengembangan karir karyawan di PT Pegadaian Kanwil I Medan, khususnya terkait dengan mutasi dan promosi jabatan yang berpengaruh terhadap pengembangan karir. Tujuan penelitian ini adalah untuk menganalisis pengaruh mutasi dan promosi jabatan terhadap pengembangan karir karyawan. Metode yang digunakan adalah kuantitatif dengan pendekatan asosiatif, melalui analisis regresi linear berganda. Data dikumpulkan dengan menyebarkan kuesioner kepada karyawan di PT Pegadaian Kanwil I Medan. Hasil penelitian menunjukkan bahwa mutasi memiliki pengaruh positif dan signifikan terhadap pengembangan karir (t-statistics = 4,321; p-value = 0,000), begitu juga promosi jabatan yang juga berpengaruh positif dan signifikan (t-statistics = 2,876; p-value = 0,004). Secara simultan, keduanya memberikan pengaruh yang signifikan terhadap pengembangan karir karyawan, dengan nilai F sebesar 10,708 (p-value < 0,001). Penelitian ini menyarankan PT Pegadaian untuk memperkuat kebijakan mutasi dan promosi yang terstruktur serta menyediakan pelatihan berkelanjutan untuk meningkatkan keterampilan karyawan dan efektivitas organisasi.

Abstract

With an average error rate of 2.3%, the production of fuel transportation tanks at PT Sejahtera Mandiri Pekanbaru has defects that exceed the 2% tolerance level. Porosity, undercut, and crack are the most frequent types of defects that result in additional cost and rework time. This study aims to improve the quality of the fuel transportation tank production process at PT Sejahtera Mandiri Pekanbaru. Data shows that production errors such as porosity, undercut, and cracks have an impact on the quality of the final product. This study used a 2k full factorial design to find the main components that affect the quality of welding results. The results show that operator certification and electrode temperature oven parameters have a great influence on manufacturing defects. Maximizing the use of electrode oven at 260°C-425°C for 1 hour, electrode moisture can be eliminated and porosity can be reduced. The DoE approach is good for finding and optimizing production features to reduce defect rates. This study suggests operator training and control of process parameters to improve welding quality.

Abstract

Driver drowsiness is a critical road safety issue responsible for thousands of traffic fatalities annually, particularly on monotonous road environments such as toll highways. This research introduces an Electroencephalography (EEG)-based driver drowsiness classification model using a Support Vector Machine (SVM) algorithm, with Observer Rated Sleepiness (ORS) as the ground truth. Data were collected from 22 licensed drivers who completed a 90-minute monotonic driving simulation in an ergonomics laboratory using the Muse S portable EEG device. The features extracted from the EEG consisted of mean and standard deviation for delta, theta, alpha, and beta band power each (14 in total) per one-minute epoch, as well as relative band power for each band and two ratios: the theta/alpha (?/?) ratio and (theta+alpha)/beta ((?+?)/?) ratio. Each classification was carried out using an SVM with a Radial Basis Function (RBF) kernel, and a One vs Rest (OvR) multi-class strategy, and the generalization power was validated using Leave-One-Subject-Out Cross Validation (LOSO-CV), which exhibits subject-independent generalization. Results showed an average LOSO-CV accuracy of 71.97% (SD = 14.67%) with a Macro-F1 score of 0.7187. The ?/? ratio was the most discriminative feature, increasing from ?0.54 (alert) to 1.59 (severely drowsy).
