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

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

The decreasing availability of fossil fuels and their contribution to environmental degradation and emissions of harmful gases has encouraged a shift to renewable energy sources. This change aims to produce electricity without using fossil fuels. Banyak Islands, a new tourist destination in Aceh Singkil, Indonesia, is experiencing an increase in visitors, increasing electricity demand currently supplied by diesel power plants. Therefore, this research aims to examine the possibilities of wind and solar power plants and assess their energy output. The four factors used to determine the potential of renewable energy are technology, economics, environment, and social politics, with 13 sub-criteria. Analytical hierarchy process techniques prioritize potential alternative energy sources such as wind and solar power facilities. Research findings show that environmental criteria have a higher value (0.3455) than financial criteria (0.2861), next is technological criteria (0.1734), then socio-political criteria (0.1603). Based on the results of the requirements and sub-requirements, wind power generation is the most effective and efficient alternative energy used in the Banyak Islands region (0.549), followed by solar power generation (0.451). This data shows that the area is prone to medium to high wind speeds, specifically in geographic locations facing the Indian Ocean which is located offshore.

Abstract

The decreasing availability of agricultural land due to urbanization threatens farmers' income and agricultural sustainability. Hydroponic cultivation offers a solution by maximizing limited land, especially in urban areas. However, challenges in managing nutrients and watering systems remain a key research focus to enhance hydroponic efficiency and support environmental sustainability and food security. This research aims to control water flow, watering, and nutrition based on a schedule regulated by the RTC DS3231 and to manage the water volume in the reservoir using the HC-SR04 sensor. Based on data analysis and testing, it is concluded that the system operates effectively, regulating water flow from 08:00 to 17:00 at a flow rate of 0.001464 m³/s, watering pests at 09:00 and 17:00 for 5 minutes at a flow rate of 0.0016 m³/s, providing nutrients every three days at noon for 2 minutes at a flow rate of 0.0007917 m³/s, and managing water volume in the reservoir between a minimum of 92% and a maximum of 97%, with a total capacity of 5,214 liters. This system works well, allowing the owner/farmer to only monitor the hydroponic plants.

Abstract

The palm oil industry is a strategic sector in Indonesia; therefore, the sustainability of Fresh Fruit Bunches (FFB) supply is a crucial factor in maintaining the continuity of Crude Palm Oil (CPO) production. PT Teupin Lada experiences uncertainty in FFB supply due to its dependence on external suppliers without fixed contracts, which leads to raw material downtime and reduced operational efficiency. This study aims to forecast FFB supply and to formulate supply security strategies based on the forecasting results. The Holt–Winters method is employed because it can accommodate trend and seasonal patterns in time series data. The data analyzed consist of historical FFB supply data from January to December 2024. Forecasting accuracy is evaluated using the Mean Absolute Percentage Error (MAPE). The results indicate that FFB supply exhibits a seasonal pattern. The additive Holt–Winters model provides the best performance, with a MAPE value of 6.28%. The forecasting results are then used as a basis for developing supply security strategies, including minimum supply contracts, seasonal incentives, and backup suppliers.

Abstract

Wilayah kepulauan dan pesisir masih menghadapi berbagai tantangan dalam mewujudkan transisi energi rendah karbon, terutama akibat tingginya ketergantungan terhadap energi fosil berbasis diesel dan rendahnya literasi masyarakat mengenai pemanfaatan energi terbarukan serta green finance. Kondisi tersebut juga terjadi di Kepulauan Banyak, Kabupaten Aceh Singkil, dimana aktivitas industri kemaritiman seperti perikanan, transportasi laut, pariwisata bahari, dan industri pengolahan hasil laut masih sangat bergantung pada energi konvensional dengan biaya operasional yang tinggi. Di sisi lain, wilayah ini memiliki potensi energi surya dan angin yang cukup besar namun belum dimanfaatkan secara optimal karena keterbatasan pengetahuan teknis, minimnya akses pembiayaan hijau, dan belum tersedianya sistem pengambilan keputusan berbasis data. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas masyarakat dan pemangku kepentingan daerah melalui transfer pengetahuan mengenai green finance dan pengambilan keputusan pemanfaatan energi terbarukan berbasis pendekatan Entropy-Weighted TOPSIS. Metode pelaksanaan kegiatan dilakukan melalui observasi lapangan, sosialisasi, Focus Group Discussion (FGD), pelatihan, simulasi pengambilan keputusan, dan pendampingan teknis kepada masyarakat serta pelaku industri kemaritiman. Hasil kegiatan menunjukkan adanya peningkatan pemahaman peserta mengenai konsep green finance, pemanfaatan energi terbarukan, dan pentingnya transisi industri kemaritiman rendah karbon. Selain itu, peserta mampu memahami proses prioritas pengembangan energi terbarukan secara lebih objektif berdasarkan indikator keberlanjutan, efisiensi, investasi, dan dampak lingkungan. Kegiatan ini juga memperkuat kolaborasi antara perguruan tinggi, pemerintah daerah, dan masyarakat pesisir dalam mendukung pembangunan energi berkelanjutan di wilayah kepulauan. Program pengabdian ini diharapkan menjadi langkah awal dalam pengembangan model green finance berbasis energi terbarukan yang adaptif terhadap kebutuhan industri kemaritiman di wilayah pesisir dan kepulauan Indonesia.
