Abstract

Salah satu upaya LPKA dalam menjalankan UU No. 11 Tahun 2012 adalah melalui programpembinaan. Program pembinaan dan pembimbingan dalam LPKA meliputi kegiatan pembinaan sertapembimbingan kepribadian dan kemandirian. Pembinaan serta pembimbingan kepribadian dankemandirian yang dilakukan salah satunya adalah keterampilan kerja serta latihan kerja dan produksi.Oleh karena itu LPKA Bandar Lampung membuat program pembinaan berupa bimbinganketerampilan budidaya tanaman sayuran secara hidroponik yang bekerjasama dengan Program StudiTeknologi Produksi Tanaman Hortikultura. Tujuan kegiatan ini adalah : 1) Memberikan bimbinganpengetahuan kepada ABH mengenai budidaya sayuran dengan sistem hidroponik melaluipenyuluhan, dan 2) Memberikan keterampilan kepada ABH mengenai budidaya sayuran melaluipelatihan dan demonstrasi. Kegiatan Pengabdian kepada Masyarakat dilaksanakan di LPKA BandarLampung. Waktu pelaksanaan dari Agustus sampai September 2020. Metode pelaksanaan dilakukandalam bentuk penyuluhan dan diskusi, demonstrasi dan praktik. Kegiatan monitoring dilakukan duakali selama pelaksanaan bimbingan keterampilan, yaitu pada minggu kedua dan keempatpelaksanaan. Kegiatan evaluasi pada kegiatan pengabdian ini dilakukan dengan melihat hasil praktikbudidaya sayuran hidroponik yang dilakukan. Berdasarkan pelaksanaan kegiatan dapat ditarikkesimpulan sebagai berikut : 1) Kegiatan bimbingan dan keterampilan di LPKA berjalan dengan baiksesuai rencana, 2) Tahapan budidaya tanaman sayuran dilakukan dengan benar sehingga hasilpanen memuaskan, dan 3) Kegiatan bimbingan keterampilan yang dilakukan berhasil. Berdasarkanproses selama kegiatan bimbingan, praktik budidaya, hingga hasil panen, maka dinilai kegiatan ini100% berhasil.

Abstract

ABSTRAK Kegiatan pengabdian ini dilaksanakan di Local Education Center (LEC) Kartikatama, Metro, yang difasilitasi oleh Pemerintah Kota Metro untuk para pra purnabakti PNS di Lingkungan Pemerintah Kota Metro. Permasalahan utama yang dihadapi oleh para pensiunan ini adalah hilangnya peran individu yang telah lama menjadi bagian dari dirinya, hal ini akan memicu stress, cemas, dan bahkan depresi jika individu tidak siap untuk menghadapi masa pensiun. Kegiatan pengabdian ini bertujuan untuk memberikan pengetahuan serta keterampilan tentang hidroponik skala rumah tangga pada PNS yang akan memasuki masa pensiun, sehingga dapat memunculkan jiwa wirausaha serta dapat berkarya di lingkungan masyarakat. Metode yang digunakan pada kegiatan ini adalah ceramah dan praktik langsung untuk menyemai benih sayuran, meracik nutrisi, dan merakit instalasi hidroponik. Target utama dari kegiatan ini adalah budidaya sayuran hidroponik skala rumah tangga pada kelompok PNS pra purnabakti di Lingkungan Pemerintah Kota Metro. Hasil dari kegiatan ini yaitu meningkatnya pengetahuan dan keterampilan peserta mengenai budidaya hidroponik skala rumah tangga, yang tergambar dari terpasangnya instalasi hidroponik sederhana oleh para peserta kegiatan.   Kata kunci: Pembekalan kewirausahaan, Pra purnabakti, hidroponik, penyuluhan

Abstract

Drought constitutes a significant natural disaster with profound implications for agricultural productivity, economic stability, and ecological balance. Batam is one of the cities experiencing a high level of drought. At the end of 2022, Batam is actually on the verge of drought. The purpose of this study is to find out information on the distribution of potential for drought in Batam and the dominant factors affecting the potential for drought occurred using NDVI and TCT algorithms. This research employed remote sensing and GIS techniques, using Landsat 8 images to acquire parameters from NDVI, TCT, and Rainfall data, which are then processed through scoring and overlaying. The final step was to validate the vegetation index parameter by taking the coordinates. The final result is a map of the potential for drought in Batam, consisting of 5 classes of potential for drought.  The area with a very low potential for drought was located mostly in Sagulung, with an area of 2.661,89 Ha. The areas with low potential for drought were mostly located in Nongsa, Batam Center, Batu Ampar, Bengkong, Lubuk Baja, and Batu Aji, with an area of 7.175,22 Ha. The areas with a very high potential for drought were mostly located in Galang, Bulang, and Belakang Padang, with an area of 19.744,76 Ha. The area with moderate potential for drought was mostly located in Sungai Beduk, with an area of 22.122,71 Ha. The areas with high potential for drought were mostly located in Galang and Bulang, with an area of 35.663,89 Ha. It is concluded from the results of this research that the collective classification of high and very high drought potential levels covers up to 64% of the entire research area.

Abstract

The battery has the function of an electrical energy storage system. However, charging the battery is prone to damage. Damage to the battery is often caused by overcharging. The time used during the battery charging process is an important factor that must be considered when charging. thus, efficient battery charging is important and very necessary to avoid damage. An another important aspect of a battery charging method is the current and voltage values supplied during its charging process. The presence of inappropriate values damages and reduce battery life, while the maintenance of a constant current is an important charging process step that extends service life. This research is expected to create a safe and optimal battery charging system with a simple low-cost circuit based on constant current by utilizing the LM388 Integrated Circuit (IC) regulator. This study discusses a 12 V battery charging system with monitored and controlled constant current using an R-Shunt sensor. Voltage monitoring while charging was carried out with voltage sensors using a constant current of 0.1 to 1.3 Ampere. Furthermore, voltages and currents were displayed through a Liquid Crystal Display (LCD) screen controlled with Arduino Uno during battery charging. The measurement results showed that the circuit reached voltages and currents of 14.07 V and 0.19 A respectively for a charge duration of 8 hours.
