Abstract

In Indonesia, agricultural practices remain largely dependent on traditional methods, particularly in plant care and irrigation management. Such reliance often results in inefficient water use and inconsistent crop yields, underscoring the urgent need for technological innovation in precision agriculture. The integration of affordable microcontroller-based systems offers a practical solution for smallholder farmers to enhance crop productivity and resource efficiency. This study investigates the application of an Arduino UNO microcontroller integrated with a soil moisture sensor for the cultivation of water spinach (Ipomoea reptans Poir) under controlled irrigation conditions. Four soil moisture ranges were tested: 80–100%, 60–80%, 40–60%, and 20–40% of field capacity. The research objectives were to: (i) optimize the operation of the Arduino microcontroller for automated irrigation, (ii) evaluate the effects of different soil moisture levels on water spinach growth, and (iii) determine the optimal moisture range for maximizing growth and yield. The results demonstrate that the Arduino-based system reliably regulated soil moisture according to programmed parameters, enabling precise, automated irrigation aligned with crop water requirements. Growth performance varied significantly across treatments, with plants maintained at 80–100% of field capacity showing the highest growth rate and yield. Notably, water spinach cultivated at 40–60% of field capacity still produced marketable crops, indicating potential water-saving benefits. This research highlights the contribution of low-cost microcontroller technology in advancing precision agriculture for leafy vegetables. It provides practical insights for sustainable irrigation management, offering farmers a feasible pathway to improve productivity while conserving water resources.

Abstract

Perubahan iklim berpengaruh pada berbagai sektor, seoerti pertanian yang berpotensi mempengaruhi ketahanan pangan nasional. Perubahan iklim juga membawa dampak dalam kehidupan masyarakat seperti banjir, longsor dan kekeringan, berkurangnya ketersediaan air, ekonomi petani dan nelayan, tergenangnya daerah pesisir, dan penyebaran penyakit pernafasan. Kegagalan dalam memahami kerentanan suatu wilayah/komunitas terhadap bencana akibat perubahan iklim akan mempengaruhi perencanaan dan anggaran desa dalam menghadapi bencana. Tujuan kegiatan pengabdian kepada masyarakat ini adalah untuk menilai ketahanan atau kerentanan dua desa tersebut terhadap dampak perubahan iklim, Kegiatan dilakukan melalui pengumpulan data primer dan sekunder, kunjungan lapang, wawancara dan pengisian kuesioner. Kerentanan dan kapasitas masyarakat dianalisa melalui metode yang sederhana yaitu memberi indeks karena tidak cukup data yang didapatkan.  Hasilnya menunjukkan kapasitas Desa Tulus Rejo dan Tegal Yoso adalah 1.964 berbanding 1.7 sedangkan kerentanan adalah 1.6 berbanding 2.04.  Kedua desa ini berpotensi tahan dalam menghadapi dampak perubahan iklim, tetapi masih diperlukan pelatihan untuk peningkatan kapasitas  pemerintahan setenpat. Hasil yang didapat dari kegiatan ini adalah diterbitkannya keputusan Bupati lampung Timur untuk pembentukan kelompok kerja pembangunan rendah karbon dan berketahanan iklim.

Abstract

Corn (Zea mays L.) is a strategic commodity after rice so that the productivity need to be optimize through nitrogen fertilization. The aim of this research is to evaluate the effect of various doses of urea fertilizer on the growth rate and yield of hybrid corn and local corn. This research was conducted from June to October 2022 on the pilot land of the Agricultural Training Center (Bapeltan), Hajimena, Bandar Lampung. The factorial experiment (5x2) was arranged in a randomized complete block design with 3 replications. The first factor is urea fertilizer doses, namely: 200 kg/ha (N1), 250 kg/ha (N2), 300 kg/ha (N3), 350 kg/ha (N4) and 400 kg/ha (N5), while other fertilizers were given to all experimental plots in the same rate (150 SP-36 kg/ha and 100 kg KCl kg/ha). The second factor is the corn variety, included V1 (BISI-18) and V2 (Tongkol Merah) varieties. The results showed that increasing dose of urea from 200 to 400 kg/ha was not able to increase the growth rate of both corn varieties. The productivity of the BISI-18 corn variety is higher than that of the Tongkol Merah as indicated by the wet weight of the cobs (g), the dry weight of grains per plot (g), and the yield of corn dry grains (tons/ha). The yield of dry corn seeds for the BISI-18 corn variety was 11.7 tons/ha, while for the Tongkol Merah variety was 9.44 tons/ha. Keywords: Fertilizer dosage, Hybrid corn, Local corn, Nitrogen use efficiency, Yield.
