Abstract

Water shortages during the dry season are the main problem for rice farmers in Pruwatan Village, Brebes District, Central Java. Currently, many rice fields in Pruwatan Village are rain-fed. This condition has been caused by natural disasters since 2010, which have resulted in dams breaking and landslides in irrigation canal cliffs. To meet water needs, this community service activity has built a solar-powered pump installation to raise water from the Pemali River that flows through Pruwatan Village to be channeled into the irrigation canal. The solar-powered pump uses an off-grid model (independent electricity without a PLN network connection) and without batteries. The pump used is a submersible type. The electrical energy to drive the pump comes 100% from the installed solar panels. The main device of the solar-powered pump consists of a series of 10,000 Wp solar panels, two units of 3 HP built-in inverters, two units of 3 HP submersible pumps, and a safety circuit (MCB). The pumps used are two 3 HP submersible pumps installed in parallel. The pump raises water from the Pemali River to the irrigation channel about 120 meters away with an elevation of 30 meters. The built-in inverter has a short circuit safety device, over/under voltage and undervoltage detection, and easy and user-friendly operation.

Abstract

This research describes and verifies the creation of a straightforward system for determining liquid diffusion coefficients using the Laser Beam Deflection (LBD) technique for measuring diffusion rates in sodium chloride solutions. The system exploits refractive index gradients that develop during diffusion to produce a detectable laser beam deviation, which is subsequently analyzed to calculate diffusion coefficients. Our experimental setup, which builds on Wiener's original design with several improvements, consists of a laser source with a cylindrical lens, a diffusion cell, and a screen for capturing projected images. We conducted an in-depth analysis of time-dependent measurements (5, 20, and 45 minutes), concentration variations (20/100, 25/100, and 30/100 NaCl/aquades ratios), and geometric configurations (30°, 45°, and 60° tilt angles) and found that the initial diffusion coefficients exhibit time-dependent behavior before stabilizing at approximately.  Within the examined range, concentration had a negligible impact on diffusion coefficients, but the geometric orientation had a substantial effect on measurement accuracy, resulting in a measurement error of approximately 3.00% when the configuration was set at 45°. Linear correlations between the natural logarithm of the ratio of the concentration difference to time, and the inverse square of the height, were found to be consistent with Fick's second law of diffusion under all tested conditions. This non-invasive approach offers a dependable substitute for conventional methods of diffusion measurement, which may be utilised in fields such as solution chemistry, food science, and pharmaceutical formulations.

Abstract

Horticultural vegetables are one of the commodities that are widely cultivated in the tropics. The information is tried to be applied in the implementation of the Collaborative Social Building Community (KOSABANGSA) 2023 program. The purpose of this kosabangsa program is to determine the level of understanding of farmers on the cultivation system of horticultural vegetables. The method of service in the 2023 Kosabangsa program activities was carried out observatively and kuesioenr sharing conducting direct counseling in Wonopringgo Village, Pekalongan. The results of identifying the impact of this service showed that there was a very significant increase in farmers' understanding (50% increase by farmers) regarding horticultural vegetable cultivation. In addition, there was also an increase in knowledge by farmers about the types of horticultural vegetable commodities. From the original only 22 farmers who understood about horticultural vegetable commodities, after the extension there were 27 farmers who understood. The most noticeable impact is the increase in farmers' understanding of the horticultural vegetable cultivation system on critical agricultural land. This is evidenced from the beginning (before counseling) only 5 farmers who understand, but after counseling increased drastically to 26 farmers. Farmers also feel that this extension activity provides great benefits for them, so this program is very worthy of being developed further. The conclusion from the results of this service is that the majority of farmers in Wonopringgo village really understand the concept of horticultural vegetable cultivation which can be implemented on marginal land with various types of suitable vegetable commodities.

Abstract

Desa Karanggondang Kecamatan Mlonggo Kabupaten Jepara merupakan kawasan pesisir di pantai utara Jawa Tengah yang memiliki panjang garis pantai 4,8 km dengan luas daerah pantai mencapai 1.214 Ha. Lahan pasir pantai merupakan salah satu lahan marginal yang memiliki banyak faktor pembatas seperti kandungan bahan organik rendah, kesuburan tanah rendah, tinggi evaporasi, temperatur tinggi serta angin yang dapat membawa garam. Namun lahan pasir pantai memiliki potensi sebagai lahan pertanian karena arealnya yang luas dan datar, adapun faktor pembatas tersebut dapat diminimalkan melalui masukan teknologi dan modifikasi lingkungan. Petani di Desa Karanggondang enggan mengusahakan budidaya di lahan pasir pantai karena keterbatasan pengetahuan yang dimiliki. Dilatarbelakangi oleh rendahnya pengetahuan petani mengenai budidaya hortikultura di lahan pasir pantai dan potensi dari usaha tani di lahan pasir pantai itu sendiri maka keterampilan petani dapat ditingkatkan. Metode kegiatan meliputi koordinasi dengan mitra, forum group discussion, sosialisasi dan pendampingan. Melalui kegiatan pengabdian kepada masyarakat ini petani mendapatkan pengetahuan baru tentang cara bertanam bawang merah dan masukan teknologi yang dapat diterapkan pada lahan pasir pantai.

Abstract

ABSTRACTNutrition  pumps  pressure is important in aeroponic. Optimal  pump  pressure produces well oxygenation, so that increases the dissolved oxygen content in the nutrition. It is good for plant roots. The purpose of this study was to determine pump pressure on the growth and yield  potato seeds grown in aeroponics in lowland 125 m asl with root zone cooling. This study used a randomized block design non factorial. Data were analyzed using analysis of variance followed by a further test of orthogonal contrasts at the level of α = 5%. Results showed that different pump pressure on the provision of nutrient, temperature cooling in the root zone gave different results on the number of potato tubers per plant and weight per tuber in each variety. Root zone cooling temperature 15 °C, the pump pressure> 1.5 atm produce highest number of tubers per plant, i.e. 11.8 tuber of Granola variety and 8.2 tuber of Atlantic variety.  The was no tuber produced from control (without referigeration). The highest weights per tuber (10.35 and 5.01 g for Atlantic and Granola variety, respectively) were reached with cooling temperature at 15 °C and the pump pressure > 1.5 atm.Keywords: evaporative cooling, hydroponics, potato, tuber, variety

Abstract

Hidroponik sebagai teknik budidaya tanpa media tanah merupakan salah satu upaya peningkatan produktivitas, efektivitas, dan efisiensi budidaya sayuran dan buah pada daerah dengan keterbatasan lahan. Makalah ini menyajikan kegiatan penerapan teknologi otomatis untuk budidaya hidroponik di Kelompok Wanita Tani Srikandi di Desa Karangbanjar, Kecanatan Bojongsari, Purbalingga. Kelompok Wanita Tani Skrikandi mempunyai usaha produksi buah-buahan dalam sebuah screenhouse yang menggunakan teknik hidroponik. Namun, praktiknya masih konvensional, manual, sederhana, memerlukan waktu dan tenaga banyak, serta masih terkendala pada kondisi lingkungan berupa iklim. Tujuan kegiatan ini adalah penerapan sistem otomatisasi berupa kendali pH, TDS, EC, suhu, dan kelembapan pada greenhouse secara otomatis. Kegiatan alih teknologi berupa penyuluhan, pelatihan, praktek langsung, dan pembuatan demplot di lokasi mitra. Hasil kegiatan adalah penggunaan sistem otomatisasi pada hidroponik memberikan kemudahan pengukuran dan efektivitas waktu yang digunakan. Kesimpulan kegiatan bahwa sistem otomatisasi ini berhasil mengurangi ketergantungan pada tenaga kerja manual dan membuka peluang pengembangan pertanian presisi yang lebih berkelanjutan, sekaligus menjadi platform pembelajaran yang efektif bagi petani dalam mengadopsi teknologi pertanian modern.
