Abstract

Drip irrigation and self-watering are two examples of irrigation technology improvements that employ effective and efficient watering methods. Water productivity may be used as a benchmark to compare irrigation efficiency and agricultural productivity. The purpose of this study was to assess mustard green's water productivity under conventional, drip, and self-watering irrigation systems. The effect of irrigation variation on mustard green growth was studied using a nonfactorial technique with a completely randomized design (CRD). The design has three treatments and six replications. This study examined the following variables: height, number of leaves, yield, irrigation water utilized, and water productivity of mustard green. The study found that mustard green plants require 0.69 mm/day of water in the vegetative phase, 2.83 mm/day in the generative phase, and 1.69 mm/day in the final phase. The use of different watering systems has a significant influence on mustard green's height and leaf number. Self-watering at 15 g/L provides the maximum water productivity for mustard green, followed by drip irrigation at 8.46 g/L and conventional irrigation at 7.69 g/L. Keywords: Drip irrigation, Mustard green, Self-watering irrigation, Water productivity

Abstract

Energi air menjadi Energi Baru dan Terbarukan (EBT) yang tengah digalakan saat ini. Dalam pemanfaatannya energi air dapat diaplikasikan menjadi suatu pembangkit listrik, salah satunya Pembangkit Listrik Tenaga Mikrohidro (PLTMH). Di Indonesia sendiri PLTMH telah banyak dikembangkan, terutama dalam mengatasi keterbatasan energi listrik di daerah terpencil. Namun, PLTMH masih belum berkembang secara optimal karena masih bertumpu pada aliran air dengan head tinggi, seperti air terjun. Hal ini tentunya menjadi perhatian khusus untuk memilih lokasi implementasi. Oleh karena itu dilakukan pengkajian dengan mempelajari bagian utama dari PLTMH, yakni dengan menggunakan turbin vortex. Berdasarkan julukannya turbin vortex memanfaatkan pusaran air dalam sistem kerjanya yang mampu diterapkan pada aliran air dengan head rendah, seperti aliran sungai. Dalam sistem kerjanya, turbin vortex harus memperhatikan jumlah sudu yang digunakan karena hal tersebut mempengaruhi kinerja turbin vortex dan keluarannya. Kajian teoritis ini dilakukan untuk mengetahui pengaruh jumlah sudu ditinjau dari keluaran PLTMH yang didasari dari sumber literatur terdahulu. Metode yang digunakan adalah metode deskriptif analitik dan kualitatif. Hasil dari kajian teoritis dapat diketahui semakin banyak jumlah sudu yang divariasikan maka akan semakin besar keluaran PLTMH, seperti nilai putaran turbin, nilai putaran generator, tegangan, arus, daya, torsi, dan efisiensi.

Abstract

Drip irrigation technique, in combination with the utilization of organic matter like as biochar and cocopeat, can increase water productivity by tailoring irrigation water to plant demands. This study was to investigate how organic matter can improve water productivity in mustard green production utilizing a drip irrigation technique. The greenhouse pot experiment analyzes the effect of adding varying quantities of biochar and cocopeat to mustard greens' growth medium using a drip irrigation technique. The findings indicate that adding organic matter reduced the quantity of water needed for irrigation. The soil and biochar combination treatment at a 1:1 ratio resulted in the highest water productivity for mustard green, whereas the control treatment produced the least. Mustard green grows optimally in a soil + biochar (1:1) growing medium, yielding the most water productivity at 16.8 g/L. Biochar can boost biomass yield by twice as much as the control treatment. Furthermore, biochar can increase mustard green water productivity by more than 300% when compared to mustard green, which relies solely on soil for planting medium. Further study is needed to investigate the effects of biochar features on water holding capacity, field capacity, and wilting point in different soil types to improve irrigation efficiency. Keywords: Drip irrigation, Irrigation efficiency, Organic matters, Water productivity.
