Abstract

PT XYZ is a private company engaged in freight forwarding, there are several problems that cause its workers to experience discomfort in special body areas caused by non-optimal work positions and lack of adequate facilities in the loading and unloading process. The purpose of this study was to determine the dominant injuries experienced by workers, proposals for improving work posture, and proposed facility designs for loading and unloading workers. The methods used Biomechanics and NIOSH with the help of 3D SSPP applications. This study examines the posture of workers, proposals for improving work posture, and proposals for the design of work facilities. This research was conducted because there were complaints from workers who often experienced injuries. From the results of this study, it was found that the most common injuries experienced by workers who carry out loading and unloading are in the back area and the lower part of the arm. The results of improved suggestions related to work posture show that the resulting angle is 50 degrees on the palm, 43 degrees on the forearm, 58 degrees on the upper arm, 49 degrees on the back, 57 degrees on the abdomen, and 21 degrees on the thigh can reduce the risk of injury. In addition, the proposed improvement of facilities is that the use of hand trolleys can also reduce the risk of injury and can increase worker productivity.

Abstract

The high production yield in the agricultural sector is undoubtedly related to the processing of agricultural products. Currently, the community in Sinarsabungan Village still prefers selling whole corn instead of corn flour, including the Sinta Uli Farmers' Group. However, in general, corn flour is more expensive than whole corn because it is more nutritious and used for direct consumption or as a higher-quality raw material for animal feed. Therefore, a milling machine is needed to facilitate the farmer group members in corn milling. Subsequently, data collection in the form of the voice of the customer was conducted through observations, interviews, and questionnaire surveys. Through this research, a corn milling machine was designed using the Axiomatic House of Quality (AHOQ) method, which can be used by the farmer group as an appropriate technology in the agricultural sector. The design parameters were obtained from the AHOQ mapping, which included using sieves with fineness levels of 40 mesh, 80 mesh, and 100 mesh. The machine was driven by a 6.5 hp gasoline-powered engine with a shaft rotation of 3250 rpm and utilized a drive wheel. Subsequently, the design was created using Solidworks software. The resulting design was then developed into a product and subjected to testing. The results showed that the milling machine was capable of producing a milling capacity of up to 70,092 kg/hour, and the milling output met customer requirements. The equipment was constructed using iron material with a weight of 60 kg.

Abstract

The growth of the number of companies engaged in delivery services has given rise to intensified market competition. Therefore, companies need to provide the best service quality by considering competitor performance to win market competition. This study aims to analyse the quality of delivery services based on service quality attributes in SERVQUAL and location factor. The case study was conducted at X as the focal company and Y as a competitor. The research instrument used a questionnaire containing questions related to the level of service importance and the perceived service for each company, as well as the level of desired service by consumers. A total of 100 respondents, specifically individuals utilising service provided by X and Y, were surveyed using the purposive sampling technique.. Data analysis was carried out with CZSQ-CZIPA technique to facilitate a comprehensive evaluation of the services quality provided by the company, with a particular focus on consumer desires and make service quality from competitors as a minimum limit of services provided. The results showed that there were 6 service attributes with a CZSQ value < 0, which means that consumers feel dissatisfied with the services of J&T Express. Furthermore, it was established that 16 service attributes are situated to the left of the ideal line, indicating that service quality provided by X was lower than Y. A mapping on the CZIPA matrix indicated that there were five attributes situated within quadrant A, which signifies the necessity for improvement. They are timeliness of delivery, responsiveness to complaints and information to consumers, media available for criticism and suggestions, and ease of access to agent locations. The attribute with the highest priority for improvement is timeliness of delivery. The findings of this study are expected to be reference for company to allocate its resources for improving the service quality in accordance with the identified priorities.

Abstract

Baby diaper waste management is becoming an increasingly pressing environmental issue due to the high use of disposable diapers in the community. The lack of waste management infrastructure and low environmental awareness are the main obstacles in increasing public participation in the collection of baby diaper waste. This study aims to identify the factors that influence the level of consumer willingness to collect baby diaper waste and determine the expected compensation expected by consumers. Multiple ordinal regression and Contingent Valuation Method (CVM) were used to achieve these objectives. The results of multiple ordinal regression analysis show that several independent variables have a significant influence on community participation in baby diaper waste management, including Environmental Awareness (X1), Infrastructure Availability (X2), Knowledge and Education (X3), Economy (X4), Policy and Regulation (X6), Ease of Access and Facilities (X7), and Culture and Social Norms (X8). Meanwhile, Community Involvement (X5) did not show a significant effect. Of these variables, Infrastructure Availability (X2), Culture and Social Norms (X8), and Policy and Regulation (X6) show the most significant influence. Based on the CVM results, the average expected compensation for community participation is Rp1,250 per kilogram of dry diaper waste. These findings suggest the importance of improving waste management infrastructure as well as supportive policies to encourage community participation. In addition, attractive economic incentives need to be implemented to strengthen community involvement in the collection of baby diaper waste. This study provides insights for stakeholders in formulating policies that support the development of effective and sustainable community participation-based waste management programs.

Abstract

XYZ MSMEs engaged in convection screen printing recorded a fairly high level of product process defects that resulted in product defects with an average defect of 5%. Some of the causes of failure in the production process include images that are not clearly printed, images that are sit-inspired, inappropriate cuts, untidy seams, t-shirts that are stained with screen printing ink, and faded screen printing results. Efforts to reduce these various problems are carried out by identifying potential failures in the production process using the Multi Attribute Failure Mode Analysis (MAFMA) method. This method produces the highest alternative weight value so that it makes it easier to make action decisions. There is one most potential failure, namely untidy seams with a total value of 0.244. The improvement strategy is carried out by paying attention to the causes of potential failures by looking at influential factors, namely human, machine, material, method and environmental factors analyzed using fishbone diagrams. Operators who are not careful and in a hurry when working, the condition of sewing machines and screen printing presses that are poorly maintained, sewing thread materials and screen printing dyes that are inconsistent in quality, there are no SOPs for operators and an uncomfortable working environment that affects the quality of the sewing and screen printing results produced. Improvement proposals are made by conducting training for workers, performing scheduled machine maintenance, checking materials before the production process, selecting trusted suppliers, making SOPs for operators and regulating production room conditions so that operators are comfortable when working.

Abstract

Good production planning can meet the demand and availability of raw materials, as well as proper production planning and scheduling, production control, inventory control, and evaluation. PDAM XYZ produces clean water for the Banyumas Regency area. Water demand at PDAM XYZ is starting to exceed the production capacity limit, so a capacity addition plan is needed to meet the customer's clean water demand. The addition of capacity can be calculated by calculating demand forecasting. Thus, this study aims to determine the best forecasting method for making water demand forecasting calculations at PDAM XYZ and the estimated amount of water demand at PDAM XYZ in the next five years. The forecasting methods used are least square and regression. The accuracy values compared are MAD, MSE, RMSE, MAPE, and Tracking signal. The results of the comparison state that the regression method is better with a MAD value of 129938.4, MSE of 28536740000, RMSE of 168928.2, and MAPE of 0.05. So, in planning the addition of production capacity, the regression method can be used to forecast calculations as a reference for determining the additional production capacity. The forecasting results using the regression method show a value of 4,352,051 m3. Based on these results, it is expected that PDAM XYZ will be able to map the amount of clean water demand so that customer water needs can be met.
