Abstract

The need for clean water around the world is related to the increasing population, especially in Teupin Batee Village, Aceh Besar District. In addition to surface water, groundwater is one of the potentials that can be utilized by the community, particularly for household needs. The purpose of this study is to identify the aquifer layer using the geoelectric method. One of the geophysical methods that can be used to map groundwater potential is the geoelectrical method based on the resistivity value of subsurface rocks. This study uses the Wenner-Schlumberger array because it can map subsurface structures both vertically and horizontally. From the results of the study, it was found that there are four different layers in this research area including, the top soil layer, hard rock, tuffaceous sand and sand layer as aquifer layer. The top soil layer is mixed with tuff, sand and volcanic breccia to a depth of 8 m with a resistivity value of 5-25 ?m. The Hard rock layer is at a depth of 8 m – 30 m with a resistivity value of 45-220 ?m. The tuffaceous sand layer has a resistivity value ranging from 25-55 ?m. While the sand layer or aquifer is at a depth of 10 m – 60 m with a resistivity value of <10 ?m which is separated by a layer of tuffaceous sand between the two aquifer layers.

Abstract

A composite is a technical material that is made by combining two or more materials that have different properties to become a new material with different properties. Natural fibers used as composite reinforcement are more environmentally friendly and biodegradable. The use of natural fibers as composite reinforcement in recent years has experienced very rapid development. One of them is pineapple leaf fiber. The aim of this research is to determine the effect of fiber volume fraction and NaOH immersion on the mechanical properties (Tensile Strength and Impact Strength) of composites reinforced with pineapple leaf fibers with an epoxy matrix. In this research, woven composites were made with variations in volume fraction and NaOH immersion time for the fibers, then tensile tests according to ASTM D-3039 standards and impact tests according to ASTM D256 standards. Based on test results with varying fiber volume fractions of 15%, 20%, and 25%, the strength results increase and decrease. The tensile strength of the composite tends to increase with increasing fiber volume fraction and NaOH immersion. However, the longer the soaking time, namely 4 hours, the tensile strength of the composite tends to decrease. The most optimal average value of tensile strength is at a fiber volume fraction of 25% with fiber soaking for 2 hours with a value of 23.07 MPa and the lowest average value of tensile strength is at a fiber volume fraction of 15% with fiber soaking for 4 hours with value 11.31 MPa. Meanwhile, the highest average impact value was owned by a composite with a fiber volume fraction of 20% without soaking, namely 0.0589 j/mm2 and the lowest impact value was with a fiber volume fraction of 20% with fiber soaking for 4 hours, namely 0.0124 j/mm2.

Abstract

Digital marketing merupakan salah satu alat dari strategi pemasaran yang cukup fenomenal di indonesia. Dalam era digital, konsumen cenderung mencari informasi, membandingkan produk, dan melakukan pembelian secara online. Mereka menggunakan internet dan media sosial sebagai sumber utama untuk mencari produk atau layanan yang mereka butuhkan. Pada pemberdayaan UMKM di Aceh dinilai bahwa pelaku Usaha Mikro, Kecil, dan Menengah (UMKM) masih minim promosi dan inovasi. Padahal dari segi kualitas, hal ini juga tidak kalah bagus dengan produk lainnya. Tetapi memang promosi yang kurang serta kemasan yang tidak menarik atau monoton, kurangnya promosi serta terbatasnya kemampuan membuat kemasan produk yang menarik, membuat produk-produk unggulan belum mampu banyak bersaing. Kegiatan pengabdian ini dilakukan berbentuk interaksi langsung antara tim pengabdian dengan UMKM. Kegiatan ini dilakukan secara bertahap pertama membuat pembelajaran atau sosialisasi, kemudian tim membentuk model berdasarkan informasi dari kegiatan awal dengan melihat kelebihan dan kekurangannya. Harapan akhir dari kegiatan ini adalah Program pengabdian ini akan memberikan bagi UMKM untuk menciptakan inovasi baru serta memberikan pemahaman bahwa digital marketing penting di masa sekarang Pengabdian kepada masyarakat ini pada akhirnya akan menghasilkan luaran yang akan menjadi berita secara online dan juga akan dipublikasikan pada jurnal pengabdian berbasis ojs serta surat perjanjian kerjasama dengan instansi terkait

Abstract

Visitor satisfaction greatly influences the development of the tourism industry, the development of the tourism industry in a region will give birth to other supporting businesses. The Samudera Pasai Islamic Museum is one of the cultural-based tourist attractions that displays tourist attractions in the form of fine art, historical relics and customs. The Samudera Pasai Islamic Museum is located in North Aceh Regency, Aceh Province. In 2023, the average number of museum visitors was 1,050 people and there was a significant decrease in visitors in September 2023. The purpose of this study was to determine visitor satisfaction with the quality of service provided by the management of the Samudera Pasai Islamic Museum. The method used in this study is the Service Quality (Servqual) method. Servqual is a method used to identify the level or quality of visitor satisfaction with the services provided by a service industry through five dimensions, namely tangibles (physical evidence), responsiveness, reliability, empathy and assurance by analyzing the gap between the value of perception and the value of visitor expectations. The results of the study showed that in the tangibles dimension, the gap value was obtained at -0.50, the responsiveness dimension obtained a gap value of -0.43, the reliability dimension obtained a gap value of -0.32, the assurance dimension obtained a gap value of -0.26 and the empathy dimension obtained a gap value of -0.34. These results indicate that the satisfaction of visitors to the Samudera Pasai Museum has not been achieved, so service improvements are needed

Abstract

Fuzzy logic is a control system technique in solving problems and is applied to systems, from basic systems to difficult or complex systems. Fuzzy logic is the proper method to plan an input space into an output space using MATLAB's mathematical theory of fuzzy sets. The reason for using fuzzy logic is because it is related to uncertainty. The unstable demand for blood bags in hospitals makes the supply of blood bags excessive or lacking from demand. The lack of blood supply results in the unfulfilled demand for blood needed by the hospital, while the excess blood supply worsens the quality of blood. In this study, we will predict the number of bags produced using the Mamdani Fuzzy Inference System (FIS) method based on the minimum demand and maximum demand values and the minimum supply and maximum supply that produce output from the defuzzification process. Applying the Mamdani Fuzzy Inference System (FIS) method based on demand and supply data obtains optimal output with MATLAB in predicting the number of blood bags produced. The results of the study showed that the Mean Absolute Percentage Error (MAPE) fuzzy logic Mamdani error value was 24%, the accuracy value of the Fuzzy Inference System (FIS) Mamdani in determining the number of blood bag production was 76%, and the production output generated through the Fuzzy Inference System (FIS) Mamdani was 4,774 blood bags. The number of blood requests at the hospital is 4,443 blood bags, so the amount of blood that must be produced to meet the hospital's demand is 4,774 bags.

Abstract

This study aims to identify the potential for occupational health and safety hazards using the Hazard and Operability (HAZOP) method and to provide recommendations for resolving the root causes of work accidents using Fault Tree Analysis (FTA). This study was conducted at PT. X, engaged in the plantation and processing of latex, is called Crumb Rubber. Based on data from 2022 to 2023, there are eight potential work accidents caused by several factors, such as the work environment, machines, and humans. The company has implemented an occupational health and safety program to support the safety of the company workforce. Even so, work accidents in the company still occur due to workers not being aware of the importance of occupational health and safety; this can be seen in workers who ignore their safety by not using complete personal protective equipment provided by the company. This still causes the potential for work accidents to occur. The study results show that the Hazard and Operability analysis revealed four different sources of danger that need attention: Low risk, such as split palms and slipping; Medium risk, including incidents such as sprained hands. High risk, including the potential for feet being stabbed by hooks, injured or cut hands, blistered and itchy hands, forklift accidents, and exposure to chemicals. Extreme risk is the potential for eye irritation. Based on the root causes of work accidents that have been observed using the Hazard and Operability method, recommendations were obtained using the Fault Tree Analysis method in the form of improving work attitudes, including creating a work health and safety training schedule, developing worksheets, and implementing attractive poster displays (visual displays). Recommendations for improving work environment conditions are recommended, especially managing puddles and chemical spills and optimizing machine maintenance.

Abstract

Workload is a collection of tasks set to be completed within a specific time. The workload can be broken down into "qualitative" (too much or too little) or "quantitative" (too much or too little), which occurs when people are unable to complete tasks or if they do not utilize the abilities they have in achieving a particular job. This study aimed to determine the workload of workers engaged in the sale of fresh or cut chicken meat. Cardiovascular Load is an estimate to determine the classification of workload based on the increase in work pulse compared to the maximum heart rate. The Defense Research Agency Workload Scale (DRAWS) method is a multidimensional technique that involves participants through subjective questions and assessments consisting of four workload dimensions: input demand, central demand, output demand, and time pressure. The results showed that the workload pulse using Cardiovascular Load, the level of fatigue based on workload obtained at the chicken slaughter station by worker 1 was 44.77%, and worker 2 was 41.11% with the category of improvement needed. At the chicken cleaning station, worker 1 was 44.13%, and worker 2 was 47.43%, with the category of needed improvement. At the chicken cutting station, worker 1 was 43.73%, and worker 2 was 45.85%, with the category of needed improvement. The study's DRAWS method results showed that at the chicken slaughtering station, worker 1 was 84.25%, and worker 2 was 87.05% with the overload category. At the chicken cleaning station, worker 1 was 86.75%, and worker 2 was 84.20% with the overload category. At the chicken cutting station, worker 1 was 85.75%, and worker 2 was 81.30%, with the overload category. This means that six respondents felt a high mental burden, so improvements are needed to reduce the impact of the cognitive workload of workers. The upgrades provided include the provision of chairs around the work area, especially at the chicken slaughtering station, so that workers can sit and rest for a moment to reduce the physical workload experienced by workers.

Abstract

The workload workers face can influence their performance and productivity physically and subjectively. Physical workload includes factors such as environmental temperature, noise, and lighting, which affect the worker's health, while subjective workload encompasses time pressure, effort, and stress experienced by the worker. One form of workload that can impact employees is the shift work system, which often leads to physical and psychological fatigue if not correctly managed. This Company, which implements a shift work system in its rubber processing factory, faces employee productivity and health challenges. This study aims to evaluate employees' workload using the NASA-TLX method, which measures six workload dimensions: Mental Demand, Physical Demand, Temporal Demand, Performance, Effort, and Frustration Level. The results of this study are expected to provide insights into the factors affecting employees' workload and offer recommendations for improving the work system to enhance productivity and team member well-being within the Company.
