Abstract

 Salah satu permasalahan budidaya di lahan kering adalah keterbatasan ketersediaan air untuk irigasi. Hal ini menyebabkan petani lahan kering umumnya hanya melakukan satu kali tanam dalam satu tahun. Salah satu upaya untuk mengatasinya adalah dengan menerapkan teknologi pemanenan air hujan atau air limpasan. Untuk meningkatkan produktivitas air hujan yang dipanen dibutuhkan suatu usaha dalam menghemat penggunaan air. Pengaturan jadwal irigasi berdasarkan analisis neraca air lahan harian diharapkan dapat meningkatkan nilai produktivitas air dilahan kering. Tujuan penelitian ini adalah mengkaji penjadwalan irigasi menggunakan neraca air lahan harian pada budidaya ubi jalar (Ipomea batatas L) varietas rancing. Penelitian ini dilaksanakan di kebun penelitian Ciparanje, Kampus Universitas Padjadjaran, Jatinangor pada bulan Juli sampai November 2018. Penelitian ini dilakukan menggunakan batas deplesi 20% dengan total pemberian irigasi sebesar 9.285,6 liter sedangkan deplesi 30% adalah sebesar 8.687 liter. Substitusi kebutuhan air tanaman dengan deplesi 20% dapat memenuhi 129 m2 luasan areal budidaya, sedangkan deplesi 30% dapat memenuhi 138 m2 luasan areal budidaya selama satu musim tanam. Berdasarkan hasil penelitian ini menunjukkan bahwa kebutuhan air tanaman selama satu musim tanam dapat terpenuhi dari jumlah volume air yang terdapat dalam kolam pemanenan air limpasan. Kata kunci : penjadwalan irigasi, neraca air lahan harian, lahan kering, ubi jalar.

Abstract

The Cikeruh sub-watershed is an area with a high population growth rate, which causes land conversion to occur in several sub-districts hence has implications for decreasing water availability and increasing water demand in the Cikeruh sub-watershed. This study aims to determine the status of water carrying capacity in the Cikeruh sub-watershed by comparing the ratio between water demand and availability. Water demand is calculated using the standard determined by SNI 19-66728.1, 2002; SNI 67281-2015; and the Directorate General of Human Settlements of the Public Works Service in 1996, while the sectors calculated are domestic, non-domestic, industrial, agriculture, animal husbandry, and fisheries. Water availability is calculated by estimating the volume of flow that occurs in the Cikeruh sub-watershed using the Soil Conservation Service Curve Number (SCS-CN) method from USDA involving hydrological data from 2011 to 2020. The result showed that the water availability in the Cikeruh sub-watershed in 2020 was 350,962,957.9 m3/year, while the water demand in the Cikeruh sub-watershed changes dynamically every year. The water demand in the Cikeruh sub-watershed in 2011 was 588,925,151 m3/year. In 2015, it was 754,796,534 m3/year, while in 2020 was 571,509,488 m3/year. The calculation results showed a water deficit in the Cikeruh sub-watershed, where the value of water demand is higher than the water availability, the ratio is 0.641, which means that the environmental carrying capacity has exceeded (overshoot) because the ratio value is < 1.

Abstract

Water is an essential thing for every living creature. However, it can cause several problems, namely floods, droughts, and water pollution. The Cikeruh sub-watershed area is frequently flooded, especially in the Rancaekek and Bojongsoang sub-districts, causing damage to public facilities and infrastructure and property losses. Therefore, a flood discharge analysis is carried out to determine the magnitude of the planned flood discharge in the Cikeruh sub-watershed. This study aims to obtain the deviation of the planned flood discharge value using the Mean Annual Flood method, the Rational method, the Der Weduwen method and the Haspers method with the planned flood discharge with measured data. This study uses a literature study and analyzes the frequency of the maximum precipitation to obtain the planned flood discharge in the Cikeruh sub-watershed. The results of the calculation of precipitation data using the Mean Annual Flood, Rational, Der Weduwen and Haspers methods on the frequency analysis of the measured discharge data is the smallest deviation occurs against the Mean Annual Flood method, which is 20.98% for the 2-year return period, 17.47% for the 5-year return period, 27.22% for 10-year return period, 42.68% for 20-year return period, 62.68% for 50 year return period, and 83.87% for 100 year return period. The results of this study are useful to know the methods that can be used as a reference in calculating the flood discharge plan and taken into consideration in planning the construction of waterworks.

Abstract

The hydroton planting media that is marketed has the characteristics of low water holding capacity. The addition of organic material in the form of husk charcoal, cocopeat, and compost clay can increase the water holding capacity of the hydroton so that plant productivity increases. This study aims to determine the composition of the best planting media for pakcoy plant growth in hydroponic floating raft systems. The research was carried out at the Rooftop of the Food Building of the Faculty of Agricultural Industrial Technology, Padjadjaran University. The experiment was arranged using a completely randomized design that was repeated four times and seven combinations of treatments. The composition of organic matter is added as much as 2.5% and 5% of each organic material. The variables observed were plant height, the number of leaves, root length, leaf area, wet weight, and stover weight. All data were analyzed using ANOVA followed by DMRT test at the level of 5%. The results showed that the organic matter in hydroton had a role in the parameters of growth and productivity of pakcoy plants compared to hydroton materials without comparing organic matter and the weight of root wet. The treatment of adding organic matter in the form of (husk charcoal, 5%) and (Cocopeat, 5%) is a treatment that affects the root length and weight of root wet.
