Abstract

The community service program on red Bangkok tilapia farming at Pokdakan Rejoayu aims to enhance members’ skills, production efficiency, and pest control through the application of ultrasonic technology. The main challenges faced by the partner group are limited technical knowledge, high feed costs, and frequent attacks from otters and herons. The program activities included socialization, training, application of ultrasonic devices, and continuous assistance. Preliminary results show an increase in members’ skills from 25% to 80%, representing a 55% improvement. The use of ultrasonic devices reduced pest attacks by 50–60% and increased the survival rate of fish from 60–65% to 75–80%. Growth performance also improved, with the harvest period shortened by approximately one month. In addition, the use of locally based self-produced feed reduced dependence on commercial feed by 20–30%, saving around IDR 1.5–2 million per cycle. Potential yields increased by 30–40%, while profits rose from IDR 3–4 million to IDR 5–6 million per cycle. These findings confirm that the program is effective and has the potential to deliver sustainable impacts on the welfare of the partner community.

Abstract

Kegiatan pengabdian ini bertujuan meningkatkan pengetahuan, keterampilan, dan kapasitas ekonomi masyarakat melalui pemanfaatan teknologi solar system serta pengembangan eduwisata kolam nila larasati di Pokdakan Rejoayu, Argorejo, Sedayu, Bantul. Permasalahan mitra meliputi keterbatasan penerangan kolam pada malam hari, belum optimalnya pemanfaatan energi ramah lingkungan, dan belum berkembangnya potensi kolam sebagai destinasi edukatif. Metode yang digunakan adalah pendekatan partisipatif melalui sosialisasi, pelatihan teknis, instalasi lampu tenaga surya, dan pendampingan pengelolaan eduwisata. Evaluasi terhadap 25 responden menggunakan angket skala Likert menunjukkan peningkatan signifikan pada aspek pengetahuan (42,7%), keterampilan (41,6%), dan persepsi ekonomi (36,1%), dengan nilai N-Gain 0,63 kategori sedang–tinggi. Sebanyak 88% responden menyatakan program meningkatkan kapasitas teknis dan membuka peluang ekonomi baru. Integrasi energi terbarukan dan eduwisata berbasis komunitas terbukti mendukung keberlanjutan budidaya serta penguatan ekonomi lokal.

Abstract

This study presents a theoretical analysis of thermal equilibration in a sphere rotating with a constant angular velocity, where part of the sphere is submerged in a hot fluid and the other part is exposed to air. The model is inspired by the traditional onde-onde cooking process, which illustrates temperature equalization through continuous rotation during heating. By applying the steady-state heat equation in spherical coordinates and imposing boundary conditions representing two temperature regions (the hot fluid at T1 and the air at T2), the criterion for rotational equilibrium is obtained. The result shows that the angular velocity must satisfy the minimum threshold ωmin=k/ρcR2, where k is the thermal conductivity, ρ is the density, c is the specific heat, and R is the radius of the sphere. When the actual rotation rate exceeds this limit, the temperature distribution becomes nearly uniform, and the entire sphere approaches thermal equilibrium. The findings clarify the physical mechanism through which rotation enhances temperature uniformity in partially immersed solids. Beyond its culinary analogy, the model offers valuable insight for rotating heat exchangers, industrial drying systems, and thermal homogenization in composite materials.

Abstract

Perancangan geometri jalan terutama dimaksudkan untuk menjaga keselamatan dan kenyamanan pengguna jalan. Interchange (simpang susun) jalan tol biasanya berupa tikungan dengan kemiringan tertentu yang dirancang agar pengemudi merasa nyaman dan aman saat kendaraan yang dikemudikannya bergerak melintas dengan kecepatan rata-rata aman. Penelitian ini mensimulasikan parameter-parameter koefisien gesek melintang antara permukaan jalan dengan ban (µs), kemiringan melintang (tanq), kecepatan rencana (v), jari-jari tikungan (R) dan derajat kelengkungan tikungan (δ) menggunakan software Excel. Pada koefisien gesekan melintang (µs) tetap, kendaraan yang bergerak makin cepat di sebuah tikungan memerlukan jari-jari tikungan (R) yang besar. Agar kendaraan tidak slip keluar dari jalur maka jalan dibuat semakin miring. Kemiringan jalan menahan kekuatan gaya sentrifugal yang menyebabkan kendaraan slip.

Abstract

Di masyarakat, termometer yang biasa digunakan untuk mengukur suhu berbasis air raksa atau alkohol. Namun, ada beberapa kelemahan termometer air raksa atau alkohol. Termometer alkohol memiliki kelemahan yaitu dinding kaca menjadi sedikit basah, sulit membaca suhu yang diukur, dan alkohol tidak berwarna. Oleh kerena itu dibuat termometer sederhana yang memiliki keunggulan seperti pembacaan suhu yang lebih teliti, lebih aman digunakan dan bahan-bahan dalam pembuatan termometer lebih sederhana. Penelitian ini dilakukan dengan cara memvariasikan setiap lilitan kawat untuk melihat perubahan yang terjadi. Data yang diperoleh dari penelitian di Logger pro dalam bentuk grafik dan nilai yang terukur. Setalah data diperoleh data di pindahkan ke MS excel yaitu nilai t waktu, nilai dari T suhu dan I Intensitas. Hasilnya Rentang suhu yang paling baik untuk melihat kemiringan kurva adalah pada suhu 38 - 100 ºC. Pada saat rentang suhu tersebut terjadi perubahan nilai yang cukup baik sehingga bisa diperoleh nilai konsistensi yang paling baik adalah pada kawat dengan 150 lilitan, nilai R2 = 0,99 dengan persamaan y = -5.5246x + 4174,5.

Abstract

This research aims to develop teaching materials for project-based learning models for science, technology, engineering, and mathematics (STEM). The procedure for developing teaching materials refers to the 4D model (Design, Define, Develop, Disseminate). The research instrument was in the form of teaching material validation sheets and science process skills tests. The design used is a non-equivalent (pretest-posttest) design. Data were analyzed using due diligence and effectiveness analysis. The product, as a result of the development, was tested and involved two covariates: initial ability and scientific attitude. The developed teaching materials have a very valid category, and the feasibility value of the science process skills test questions from the validator is 97% very good category. The resulting product is practical to apply based on the results of learning management. PjBL STEM teaching materials can improve science process skills.
