Abstract

Water Hyacinth (Eichhornia crassipes) is a tropical aquatic plant known for its extremely rapid growth, often regarded as a water weed due to its negative impacts on aquatic ecosystems. Nevertheless, this plant possesses significant potential as a raw material for handicrafts with economic value. This community service program (PKM) was conducted in Bugel Village, Panjatan Sub-district, Kulon Progo Regency, Special Region of Yogyakarta, with a dual purpose: to empower the local community by transforming water hyacinth into economically valuable craft products and, at the same time, to contribute to aquatic weed control. The primary target of the program was a group of housewives who had available time but were not yet engaged in productive activities, along with several active participants, including Hery Prazogie, Eko, Tolob, Susilo Edi, and Fauzi. The methods employed included program socialization, craft production training (covering drying techniques, material sorting, and weaving skills), basic business management training, as well as continuous mentoring and monitoring. The program was implemented over eight months, from January to August 2025. The results showed a significant improvement in participants’ skills. After three training sessions, most participants were already able to independently produce simple craft items. By the end of the program, more than 60 craft products had been successfully created, including bags, baskets, table mats, chairs, pencil holders, and various household accessories. Institutionally, the program led to the establishment of a small business group named Anyaman Bugel Mandiri “Independent Bugel Weaving”, serving as a collective platform for the community to develop creative economy-based enterprises. The program outputs also included scientific publications, promotional media (posters, features in local newspapers), and a documentary video, all of which strengthened the sustainability of the initiative. Overall, this activity demonstrates that water hyacinth once considered an environmental problem can be transformed into a new economic resource that supports the improvement of rural community welfare.

Abstract

An Anti-icing system is a system that aims to prevent the formation of ice when the plane is in the air. The formation of ice in aircraft is of great concern because an airplane flight will pass through the atmosphere, which will experience the formation of the ice at a certain altitude. The formation of such ice will cause a hazard to the aircraft. So that the ice protection system, namely the anti-icing system, is very concerned so that it is always in a serviceable condition. In this study, direct observation and fault tree analysis were used to determine the cause of failure of the Boeing 737-800 NG anti-ice system engine and anti-icing cowl inlet. The results of the analysis using the fault tree analysis method obtained essential events, namely: actuator fails, electrical connector disconnected, Control Selenoid Trouble, Regulator Trouble, Sense Line Connector Trouble, Engine Fault, Engine Control Trouble, Engine Duct Trouble, Panel Buttom Problem, EICAS Module Problem, No Source Electricity, Negative Electrical Source, Wiring Problem.

Abstract

Abstrak : Krisis air bersih di Desa Banyurejo, Kapanewon Tempel, Sleman, merupakan fenomena yang menarik untuk dikaji. Secara kenampakan permukaan wilayah ini memiliki potensi air tanah yang cukup. Namun, kondisi di lapangan menunjukkan keterbatasan ketersediaan air bersih. Pengabdian ini bertujuan untuk memahami kondisi bawah permukaan yang mempengaruhi keberadaan air tanah melalui kajian geofisika. Metode yang digunakan adalah geolistrik dengan konfigurasi Wenner–Schlumberger. Hasil pengukuran menunjukkan nilai resistivitas berkisar antara 3,7 Ω·m hingga 387 Ω·m yang mengidikasikan potensi saturasi air tanah. Variasi distribusi nilai   resisitivitas secara lateral mencerminkan heterogenitas litologi bawah permukaan khususnya dibagian Banyurejo sisi selatan. Kondisi tersebut diduga membatasi kemenerusan akuifer dan meningkatkan kerentanan terhadap penurunan ketersediaan air tanah. Alternatif yang ditawarkan yaitu peningkatan sistem resapan dan pengaturan tata ruang.Abstract: The clean water crisis in Banyurejo Village, Tempel Subdistrict, Sleman, presents a significant case for investigation. Although the surface characteristics suggest adequate groundwater potential, field observations reveal restricted access to clean water. In light of these conflicting indicators, this study seeks to analyze subsurface conditions affecting groundwater availability using geophysical methods. Specifically, the geoelectrical method with the Wenner–Schlumberger configuration was employed. Measurement results showed resistivity values ranging from 3.7 Ω·m to 387 Ω·m, indicating potential groundwater saturation. Furthermore, variations in the lateral distribution of resistivity values reflect the heterogeneity of subsurface lithology, particularly in the southern part of Banyurejo. As a result, this condition is thought to limit the continuity of the aquifer and increase vulnerability to declining groundwater availability. To address these issues, alternatives offered include improving the infiltration system and spatial planning.

Abstract

Accurate simulation of heat transfer is essential in many engineering applications. This study investigates heat transfer on thin plates by solving two-dimensional heat equations using the Smoothed Particle Hydrodynamics (SPH) method. The accuracy of the formulation is evaluated by comparing SPH results with analytical solutions for Dirichlet and Neumann boundary conditions, where small nRMSE values confirm good agreement. The method is then applied to plates with internal heat sources of different but equal-area geometries, showing that the star-shaped source yields the fastest heat transfer. These findings highlight the flexibility of SPH for modeling heat equations under complex geometries and boundary conditions.

Abstract

Penelitian ini mengevaluasi bahaya gempa di Pulau Bali dengan memperhitungkan sumber gempa lokal (fault) dan gempa dangkal (shallow background) menggunakan Probabilistic Seismic Hazard Analysis (PSHA). Nilai Peak Ground Acceleration (PGA) dari fault lokal untuk periode ulang 500 tahun berkisar 0,02–0,20 g dan untuk periode ulang 2500 tahun berkisar 0,05–0,30 g. Sementara itu, sumber gempa Shallow Background menghasilkan PGA 0,02–0,30 g untuk periode ulang 500 tahun dan 0,30–0,60 g untuk periode ulang 2500 tahun. Hasil analisis menunjukkan wilayah selatan Bali memiliki PGA tertinggi akibat kombinasi kedua sumber gempa, sedangkan wilayah tengah dan utara memiliki PGA menengah hingga rendah, tetapi tetap signifikan. Integrasi kedua sumber gempa menghasilkan peta hazard yang lebih representatif, mendukung mitigasi risiko, perencanaan tata ruang, dan desain bangunan tahan gempa.
