Abstract

Pump that operates automatically by relying on natural power from water without using great cost and trouble by pumping hydram. Hydram pumps are one of the types of pumps that are driven by kinetic power, it was discovered by a 1796 Montgolfier in Italy. The purpose is to determine the most optimal water speed of the hydram pump by using different numbers of pressure tubes and several check valves. This research uses a factorial Randomised Group Design (RGD) method. The first treatment is valve variation and the second is variation in the number of tubes. The results showed that the average river water flow velocity was 0.154 meters/second with an average water discharge of 2.61 m3/second under normal flow conditions. The average water flow in the intake pipe is 0.717 meters / second and the volume of water in the pipe is 15.19 liters with an average water discharge entering the intake pipe is 10.804 m3 / second. A combination of three valves and three tube treatments consistently produces greater water discharge than other combinations. The highest efficiency of the hydram pump is found in the combination of three checks.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan meningkatkan kompetensi teknologi energi terbarukan di SMK Negeri 4 (SKAPAT) Kabupaten Soppeng, Sulawesi Selatan, melalui implementasi trainer Pembangkit Listrik Tenaga Surya (PLTS) berbasis Internet of Things (IoT) sebagai media pembelajaran. Latar belakang kegiatan ini adalah terbatasnya fasilitas dan pemahaman guru serta siswa terkait teknologi Energi Baru Terbarukan (EBT), khususnya PLTS. Metode pelaksanaan meliputi perancangan, pembuatan, simulasi, uji coba, dan implementasi trainer PLTS skala laboratorium. Sistem yang dirancang menggunakan dua modul panel surya 120 Wp, Solar Charge Controller (SCC), inverter 1600 W, Automatic Transfer Switch (ATS) dan baterai VRLA 50 Ah. Fitur IoT digunakan untuk memonitoring tegangan, arus, dan daya secara real-time serta mengontrol beban listrik melalui aplikasi ponsel. Trainer PLTS terbukti optimal sebagai media praktikum, dan pelatihan berhasil meningkatkan pemahaman guru serta siswa tentang pengoperasiannya. Kegiatan ini mendukung SDGs 4 & 7 dan berpotensi direplikasi untuk memperluas literasi energi terbarukan di SMK lain.

Abstract

Program pengabdian masyarakat ini bertujuan untuk mengakselerasi pertumbuhan ekonomi kreatif di Desa Tabo-Tabo melalui pemberdayaan dua mitra strategis, yaitu Pokdarwis dan BUMDES Mappatuwo. Selama pelaksanaan intensif pada bulan September hingga Desember 2025, intervensi ini menghasilkan transformasi signifikan pada kedua pilar ekonomi desa tersebut. Pada mitra Pokdarwis, pendampingan yang berfokus pada profesionalisme digital berhasil menuntaskan restrukturisasi kelembagaan secara menyeluruh serta meluncurkan platform digital desatabotabo.com sebagai etalase utama yang memasarkan tiga paket ekowisata tematik melalui konten media sosial yang konsisten. Sementara itu, transformasi pada BUMDES Mappatuwo difokuskan pada penguatan literasi bisnis dan inovasi, yang dibuktikan dengan kemampuan anggota menyusun Harga Pokok Produksi (HPP) dan menggunakan aplikasi pembukuan digital. Keberhasilan ini diperkuat oleh diversifikasi produk bernilai tambah seperti "Gula Aren Mappatuwo" dan "Lele Marinasi Frozen" dengan kemasan modern, yang berdampak pada kenaikan harga jual rata-rata sebesar 25%. Selain itu, ekspansi pasar melalui e-commerce dan adopsi pembayaran QRIS telah mendongkrak penjualan digital sebesar 45%. Secara keseluruhan, program ini berhasil mencapai seluruh target luaran wajib, efektif memutus siklus stagnasi usaha, serta meletakkan fondasi kokoh bagi kemandirian ekonomi digital di Desa Tabo-Tabo.

Abstract

Traditional methods for classifying children with mental retardation based on fixed IQ score thresholds are often inadequate in capturing the diversity of intellectual abilities. This study proposes the use of data mining techniques, specifically the K-Means clustering algorithm, to group Intelligence Quotient (IQ) data derived from psychological assessments. The research methodology consists of data collection, data preprocessing, selection of the optimal number of clusters, and implementation of the K-Means algorithm. The experimental results demonstrate that the proposed approach can successfully cluster IQ data into multiple groups representing distinct levels of intellectual functioning. The resulting clusters can be utilized as a decision-support mechanism to assist educators and practitioners in selecting appropriate instructional methods and intervention strategies in the field of special education.

Abstract

This study examines the dynamics of interest contestation in developing civic virtue within Nagari communities, specifically focusing on Nagari Sungai Pua following the 2023 Nagari Head Election (PILWANA). Through qualitative descriptive research conducted over three months (October-December 2023), involving 25 key informants from various social elements, this study reveals how political contestation significantly influences the development of civic values in traditional communities. The findings demonstrate that interest contestation manifests in three primary dimensions: social fragmentation patterns, transformation of collective decision-making mechanisms, and reconfiguration of traditional value systems. The research identifies that post-election polarization has created complex alliance networks transcending traditional tribal boundaries, affecting both formal social structures and informal community dynamics. Furthermore, the study highlights how modernization pressures have led to the development of sophisticated filtering mechanisms in selecting and adapting new values while maintaining fundamental principles rooted in local traditions. This research contributes to understanding how traditional communities navigate the challenges of maintaining civic virtue amid contemporary political dynamics, offering insights for policy development in local governance strengthening and social cohesion enhancement. The study suggests that successful civic virtue development depends heavily on the community's ability to manage interest contestation through constructive dialogue and public deliberation, emphasizing the importance of developing inclusive strategies that bridge various stakeholder interests while preserving traditional values.
