Abstract

Telah dilakukan penelitian dengan menerapkan metode geolistrik self potential SP pada lokasi penelitian Pesisir Pantai Sendang Biru untuk melihat pola aliran akuifer karst. Berdasarkan analisis dan interpretasi data penyebaran anomali potensial alam positif dan negatif dengan rentang nilai potensial alam antara -10.644 mV hingga 11.294 mV diklasifikasikan menjadi zona potensial alam negatif dengan nilai -10,644 mV hingga – 0.100 mV dan zona potensial alam positif dengan nilai 0.026 mV hingga 11.294 mV, maka diperoleh hasil bahwa pola aliran akuifer karst mengalir dari arah timut lokasi penelitian ke arah barat serta potensi keberadaan akuifer menyebar di lokasi penelitian

Abstract

The study has been conducted to identify subsurface layers using the Wenner-Schlumberger geoelectric method. This research aims to understand the rock layering and hydrogeology at the research site. The research was conducted with a field survey on four 480-meter-long tracks in Bakustulama Village. Rock resistivity data was measured using a resistivity meter and analyzed using Res2DinV software to produce a 2D cross-sectional model. This method utilizes rock resistivity to determine the nature and layering of rocks in the subsurface, focusing on potentially water-saturated zones and fractures. The results show that the subsurface layer in Bakustulama Village consists of sandstone in the upper layer (0-20 meters) with medium resistivity (100-700 Ωm), followed by a highly water-saturated clay layer with low resistivity (0-100 Ωm), and a limestone layer with high resistivity (700-1000). The subsoil in the Bakustulama Area is diversely arranged, with sandstone layers at the surface to a depth of about 20 meters that suspected to have high porosity and are easily drained by water. Underneath, water-saturated clay layers are dominant and difficult for fluids to pass through.

Abstract

step towards increasing national food security, reducing economic losses on livestock, and maintaining human health. This Community Service seeks to improve community welfare by strengthening chicken breeder organizations. Empowerment is carried out through training and demonstrations of chicken farming technology, as well as increasing community support and collaboration with chicken breeder organizations in the two villages. The implementation strategy is participatory in nature which includes discussion activities and exchange of ideas between groups of chicken farmers, as well as the use of the internet and social media to increase knowledge. The findings show that training and demonstration of chicken farming technology is very useful in increasing the skills and knowledge of chicken farmer groups in solving difficulties such as dealing with chicken diseases and fighting Avian Influenza. After the implementation of the chicken farmer group empowerment initiative, community support and collaboration for chicken farmer groups in Oenaek Village has increased. It is important to expand the frequency and intensity of training and demonstrations of chicken farming technology, as well as collaboration between chicken farmer organizations in Oenaek Village. Apart from that, the use of the internet and social media as a way to increase knowledge can be used to achieve greater goals. This is expected to increase production and quality of chicken farming, as well as reduce the risk of disease transmission in Oenaek Village.

Abstract

Tujuan dari kegiatan ini adalah untuk menumbuhkan minat dan meningkatkan keterampilan kewirausahaan di antara alumni dan mahasiswa dalam budidaya lele menggunakan alat pengukuran digital. Masa tunggu yang lama untuk mendapatkan pekerjaan bisa menjadi beban psikologis bagi lulusan baru. Oleh karena itu, Program Studi Fisika Fakultas Sains dan Teknik Universitas Nusa Cendana (FST Undana) menawarkan pelatihan kewirausahaan budidaya lele untuk alumni dan mahasiswa. Pelatihan ini berfokus pada penggunaan alat berbasis digital untuk mengukur sifat fisis guna mengoptimalkan potensi budidaya lele. Pelatihan mencakup presentasi materi, diskusi, dan praktek langsung terkait budidaya lele menggunakan alat pengukuran digital. Keberhasilan kegiatan ini dievaluasi melalui pertanyaan survei yang diberikan kepada peserta. Jawaban dari hasil survei menunjukkan pelatihan ini berhasil dijalankan dengan sangat baik. Selain itu, umpan balik dari peserta menunjukkan peningkatan motivasi untuk terlibat dalam budidaya lele.

Abstract

Telah dilakukan penelitian tentang pemetaan perlapisan batuan di bawah permukaan dengan metode geolistrik resistivitas di Desa Lelogama Kecamatan Amfoang Selatan Kabupaten Kupang. Penelitian bertujuan untuk memetakan pola perlapisan batuan berdasarkan nilai resistivitas, mengidentifikasi jenis batuan di bawah permukaan berdasarkan nilai resistivitas dan menentukan ketebalan lapisan-lapisan batuan di daerah penelitian pada semua lintasan. Pengolahan data menggunakan software Res2dinv. Metode yang digunakan adalah metode geolistrik konfigurasi schlumberger. Hasil interpretasi menunjukkan bahwa pola perlapisan batuan  untuk 4 lintasan dengan panjang lintasan 400 meter dengan variasi nilai resistivitas berkisar antara 0,474 Wm–11,436 Wm, 0,777 Wm–21,231 Wm, 2,96 Wm–3.634 Wm  dan 0,637 Wm–3.085 Wm, batuan yang teridentifikasi yaitu batuan lempung, batuan aluvium dan batuan gamping yang berada pada ketebalan masing-masing yaitu lapisan batuan lempung berkisar antar 7,5-47,5 m, ketebalan lapisan batuan aluvium 5-60 m dan ketebalan lapisan batuan gamping 5 m–52,8 m.
