Abstract

One of the projects currently being undertaken by PT. XYZ is Dam “X”. Based on project management data obtained from PT. XYZ, the actual project construction process experienced a significant delay from the planned schedule, with a delay duration of approximately 30 days. The delay will have an impact on the duration of the final completion of the project, including the process of delivering project results to consumers. The purpose of this study is to determine the critical path in project implementation and identify activities that do not have slack time because it will affect the duration of the overall project completion. The method used in this study is the Critical Path Method (CPM), which is a network method consisting of a series of activity components with the longest total time and showing the fastest duration of project completion. The results showed that the Manufacturing Project has a total of 11 critical activities out of 37 activities (work packages), with a total critical time of 75 days. The total critical time from the calculation of the CPM method also shows the optimal total project duration which can be used as a reference for the project team for the completion of a fabrication project or a hydromechanical component installation project on Dam "X".

Abstract

Banana is one of the fruits widely consumed by the people of Indonesia. This can be proven by the many types of bananas that grow and are marketed in all regions in Indonesia. Banana sellers can quickly get bananas to market, and consumers can buy them at varying prices. However, the problem arising from banana fruit is its relatively short life span. It is characterized by black spots that appear on the banana and mark the banana will begin to rot. Therefore, the process of processing bananas into beru products, namely banana sales, is carried out. The service activity began with an interview with banana sellers at the Karang Jasi market and Sweta market, Mataram City. This resource person obtained information about the banana sale and how to process it. Banana sale processing is divided into three stages: banana preparation, skinning and slicing bananas, and drying. Banana drying takes ± eight days in consistently hot weather. Banana sale that is formed can be consumed directly and reprocessed into fried bananas. With this service activity, it is hoped that it can provide information to the community about how to process almost rotten bananas and use them as additional income.

Abstract

Poor management of occupational safety and health (OSH) has an impact on occupational accidents. This results in losses for both the individual worker and the company. Therefore, the occupational hazard accident risk analysis was carried out using the HIRARC (Hazard Identification Risk Assessment and Risk Control) method. Data collection was conducted from the business owners of SSBC (Sanggar Sarana Baja Cakra) Welding and Turning Shop, located in Cakranegara, Mataram, West Nusa Tenggara. There are 3 work activities for risk identification, namely the clamping process, the engraving process and the drilling process. The results of the analysis show that the highest level of occupational risk occurs during clamping and engraving process. For drilling, it's in low level of risk. As for risk management, it is mainly done for high-risk level. Immediate improvement is needed by providing personal protective equipment (PPE) to workers to reduce these risks. Based on these results, business owners can do evaluation on his business so occupational accidents can be in the workplace.

Abstract

Recenly conventional vehicles use fossil fuels, however these fuels are non-renewable energy sources and their availability in nature is very limited. If they are explored continuously then one day they will run out, so it is very necessary to save and innovate to use these sources. Other renewable energy sources, one of which is electrical energy, where this electrical energy can be generated from various sources such as water, solar, biomass and so on. Besides that, the use of electrical energy for vehicles is currently very relevant because it is environmentally friendly, that is, it does not produce CO or CO2 gas like conventional vehicles, so this energy is known as green energy. Indonesia has the potential to produce electric cars because the availability of nickel is very abundant to be processed into batteries, as a provider or energy storage for electric cars, our country has a very big opportunity to produce electric cars. To make this happen, it is deemed necessary to carry out comprehensive studies such as power steering so that comfort and safety can be achieved. The most suitable power steering is the electric power steering (EPS) type because the energy required comes from the battery. The method applied in this research is an experimental method, by measuring torque requirements on various roads, the roads chosen are asphalt roads, block paving roads and dirt roads. Based on this data, an EPS test bench then created which was able to measure the input and output torque of the EPS and look for the power consumed by the system. Road conditions can cause differences in torque requirements, in block paving road conditions the greatest torque requirement is 2.77 Nm and the smallest occurs in asphalt road conditions at 1.62 Nm. EPS testing shows that it is only loaded up to 25% with an input torque of 1,652 Nm resulting an output torque of 3,924 Nm with an electrical power consumption of 6,31 watts.

Abstract

The use of smallholder plantation land in the North Lombok district is seen from the types of plants carried out by agricultural or plantation groups consisting of coconut plantations with an area of 10,574.62 tons and a production yield of 11,397.08 tons. Coffee plants with a planting area 1,315.57 with a production yield of 780.46 tons. Specifically for coffee plantations, farmers usually only process post-harvest through drying, after which they are immediately sold. To increase the selling value, it is necessary to utilise technological results such as using a coffee skin peeler. This tool helps increase the productivity of coffee farmers. The dedication will be carried out in Selelos Hamlet, Gangga sub-district, North Lombok district. The implementation of this service program includes making a coffee peeler, presentation, and counselling on using the tool, along with demonstrations. As a result, the coffee skin peeler has a production capacity of 100 kg per hour. The quality of the coffee beans produced is clean and free of impurities. The productivity of using a coffee skin peeler machine is greater and shorter when compared to the manual process.

Abstract

In contemporary times, the use of smartphones has become an essential requirement for daily life in the digital era. The prevalent consequences of smartphone usage include the development of poor posture and behaviors. This study aimed to assess the risk of musculoskeletal disorders (MSD) among smartphone users, focusing on adolescents aged 12 to 19 years. A sample of 82 students (79.3% female and 20.7% male, with an average age of 15.7 ± 2 years and a normal BMI of 76.8%) in the West Lombok district of the West Nusa Tenggara Province in Indonesia was measured. Data collection through simple random sampling involved distributing questionnaires to participants and requesting them to provide responses based on their personal experiences. The present study employs a chi-square analysis to examine the association between smartphone usage, posture behavior, and the highest values of MSD complaints. The findings indicate that the neck (46.3%) and back (45.1%) were the body regions with the most prevalent complaints of MSD. The participants frequently engaged in standing without support and walking as their posture behaviors. There was a significant correlation between the level of neck pain and posture during walking. The use of smartphones among adolescents has an impact on the risk level of experiencing MSD complaints, thereby increasing the potential for illness and abnormalities. Hence, it is necessary to exercise sufficient control over the routine usage of smartphones to mitigate the negative impacts incurred.
