Efficient Water Use

Subak is local wisdom in Bali that has been practiced for centuries in managing irrigation water. Here we present the uniqueness of Subak to manage water with an example of Subak Sange, Gianyar, Bali. The field activity was carried out from April-September 2019. The research objectives were to analyze: (i) the characteristics of local wisdom in Subak Sange, (ii) the effect of irrigation water frequency on pest and disease outbreaks on tobacco yield, and (iii) the efficiency of water use in chili-tobacco intercropping. We combined several approaches to achieve the objectives, including an interview with farmer, diversity analysis, Romijn method, and revenue cost ratio. The results showed that the harmony of relations between farmers was bound by a belief in three elements socio-agrarian-religious. The excessive irrigation gave more pest and disease outbreaks, as shown in 6-irrigation frequencies. In addition, the occurrence of rotten root outbreaks was the highest (29%). The optimal frequency irrigation for yield of tobacco was 4-times, which produced 11.5 tons of dry chopped tobacco per hectare, and this frequency irrigation was much more efficient water use by 79% than rice plants. Based on revenue cost ratio analysis, the chili-tobacco intercropping with four times irrigation was feasible. The findings indicate that management of irrigation water in Subak Sange is promising to support food sustainability in the region.

Penelitian ini bertujuan untuk mengetahui karakteristik dan menganalisis kelayakan usahatani cabai besar dan cabai rawit di Sumatera Utara. Penelitian ini menggunakan analisis deskriptif. Data yang digunakan dalam penelitian ini adalah data sekunder. Karakteristik rumah tangga usaha tani cabai besar dan cabai rawit menunjukkan bahwa umur petani cabai besar dan cabai rawit sebagian besar berada di usia yang produktif, sebagian besar pendidikan petani masih rendah, pembiayaan modal berasal dari modal sendiri dan sebagian besar usahatani cabai besar dan cabai rawit tidak mendapatkan bimbingan atau penyuluhan. Analisis data dilakukan untuk melihat kelayakan usahatani cabai besar dan cabai rawit menggunakan analisis R/C (Return Cost Ratio) dan B/C (Benefit Cost Ratio). Berdasar hasil penghitungan pada usahatani cabai besar diperoleh nilai R/C>1 sebesar 1,56 dan B/C>0 sebesar 0,56. Penghitungan pada usahatani cabai rawit diperoleh nilai R/C>1 sebesar 1,93 dan B/C>0 sebesar 0,93. Dari hasil analisis usahatani cabai besar dan cabai rawit dapat disimpulkan bahwa usahatani ini layak dan menguntungkan secara ekonomi untuk diusahakan.Kata kunci: cabai, karakteristik, kelayakan usahataniAbstract This study aims to determine characteristics  and analyze the feasibility of chili pepper (Capsicum annuum L) and cayenne pepper (Capsicum frutescent L) farming in Sumatera Utara . This research uses descriptive analysis. The data used in this study is secondary data. Household characteristics of chili pepper and cayenne pepper farming show that the age of farmers of chili pepper and cayenne pepper are mostly in productive age; most of the farmers' education is still low; capital financing comes from their capital and most of the chili pepper and cayenne pepper farming is not get guidance or counseling. Data analysis was carried out to see the feasibility of chili pepper and cayenne pepper farming using R / C (Revenue Cost Ratio) and B / C (Benefit Cost Ratio) analysis. Based on the results of calculations on chili pepper farming obtained R/C value 1,56 and B/C value 0,56. Calculation of the cayenne farming obtained R/C value 1,93 and B/C value 0,93. From the results of the analysis of chili pepper and cayenne pepper farming, it can be concluded that this farming is feasible and economically profitable to be cultivated..Keywords: business feasibility, characteristics, chili
