The objectives of this study were to: (1) analyze the effects of different land tenure status on soil conservation level and (2) analyze the soil conservation level on production and income of upland rice farming. This research was conducted in Mausambi Village, Maurole Subdistrict, Ende Regency. Considerations in choosing a research village were seen from: a) the number of farmers who pawned agricultural land b) the extent of dry land and critical land c) the high percentage of poor farmers d) centers of food crop production and e) areas vulnerable to erosion. The population of upland rice farmers in Mausambi village was 214 people and consisted of 36 sharecroppers, 32 mortgagors and 146 owners. The method of sampling is cluster sampling, where this technique is a technique of selecting a sample from groups, small units or clusters. The sample size was calculated using Parrel formula. The sample size of land ownership status was 92 owners, 34 sharecroppers and 21 mortgagors. The analysis method used was multiple linear regression by including dummy variable of land tenure status and quantitative descriptive analysis. The result of the analysis shows that the farmers on land tenure status of owner are better in doing soil conservation efforts when compared to farmers on land tenure status of sharecropper and mortgagor. Owner dummy variable significantly affected the soil conservation level at 99% significant level. The positive sign means that the soil conservation level score on owner land tenure status is higher than the owner land tenure status of sharecropper and mortgagor. This is because in the owner farmers, the responsibility of soil conservation is higher than the farmers on other land tenure status. The well-done soil conservation efforts provide effect on the production and income of upland rice farming. The result of the research also shows that the land in the research site has not experienced severe erosion and soil conservation has been conducted but not maximized yet, especially on the aspect of contour farming, terrace treatment, terrace-strengthening plants, and tillage.

Batujai Reservoir locates in Batujai Village, Praya Barat, Central Lombok, West Nusa Tenggara. It is the primary source of irrigation water supply for agriculture in Central Lombok District with an area of around 3,235 ha. The problem is the bloom of water hyacinth weed (Eichhornia crassipes), which can cause reservoir water loss through evapotranspiration, affecting the amount of water reservoir available for the dry season. The objective was to identify the area of cover and estimate water loss through water hyacinth evapotranspiration for the period 2013 – 2017. This study used a descriptive method by analysis of secondary data which were meteorological data and landsat-8 satellite imagery. Evapotranspiration analyzes use CROPWAT 8.0, monitoring water hyacinth cover using landsat–8 satellite imagery processed using ENVI 5.3 and ArcGIS 10.4 software. The results show that the spatial distribution of water hyacinth can be detected and mapped accurately with an overall classification accuracy of 84.11% – 97.04% using Landsat 8 data, with a kappa coefficient of 0.80 – 0.96. The area of water hyacinth cover ranges from 38,400 m2 – 2,158,500 m2, with a cover area of more than 20%, causing water loss above 8,000 m3 day-1, which occurred in April 2013, April 2015, April 2016, February 2015, May 2014, May 2016 and July 2016, in those months it was seen that the amount of water loss was greater. Therefore, it is needed to suppress the growth of water hyacinth, in maintaining reservoir water storage capacity to support a systems of sustainable agriculture.

Soybean is one of the most important food commodities in Indonesia and also it has high value. The needs continue to increase each year, but not offset by increased production become an issue that must be addressed. One attempt to increase soybean production is through the cultivation in agroforestry systems through improving the quality of soil fertility. This research aims to study the effect of various doses of litter teak and NPK fertilizer on chemical soil fertility and the potential of soybeans yield in agroforestry systems based teak crops. Experiments using a Randomized Complete Block Design (RCBD) with two factors, namely litter teak doses (0 ton ha-1, 2.500 ton ha-1, 5.000 ton ha-1, 7.500 ton ha-1) and doses of NPK fertilizer (60-60-60 and 60-120-60) on Grobogan soybean varieties. The variables measured were pH, organic matter content, N-total soil, cation exchange capacity (CEC), plant tissue of N, P-total soil, and component production. Data analysis using analysis of variance F-test based on the level of 5% and significantly different variables followed by Tukey’s method level of 5%. The results showed that combination treatment with various doses of teak litter NPK fertilizers can increase total nitrogen content of the soil with the highest yield of 1.69% on S1D2 treatment, but to organic matter, CEC, pH, and total soil P not significant effect. Component of soybean varieties of the highest Grobogan of 0.83 tons ha-1 in the treatment S1D1. The result was still below the average of the national soybean production.
