Mostly, the researchers have been carried out landform using survey method and manual delineation. Integrating remote sensing data and GIS technique can automate identifying of landform using Topographic Position Index data as one of remote sensing data. The aim of paper is to identify and categorize landform element using Topographic Position Index in the Gede Watershed derived by DEMNAS with 30 m resolution and output scale of map is 1:25.000. The method was carried by algorithm of slope and TPI automation with Geographic Information System technique. To obtain the appropriate TPI with the real condition of landform, we used radius circle 5m, 10m, 25m, 50m and 100m neighborhood size cell for TPI. The combination of slope and TPI shows the best result which are appropriate with the real condition of landform is radius circles 5m neighborhood size cells. Based on the result shows five heterogeneous of landscape i.e peak (0,6%), upper slope (10%), middle slope (9,49%), lower slope (39,36%) and channel bad (40,49%). To achieve the better result, it needs intensive field survey and using high resolution imagery as accuracy test.

Organic farming is a natural cultivation system without using chemicals. These organic vegetables and ornamental fl owers are cultivated naturally by compost and using organic pesticides. The fertilizer used in this educational process is compost fermented with Local Micro Organisms or MOL, at the location of the Cahaya Alam Foundation which is located in Kucur Village, Dau District, Malang Regency. The method used is to educate about growing organic vegetables and ornamental fl owers properly, with limited land conditions. The solution given was to create an eff ective planting medium for cultivating organic vegetables and ornamental fl owers in accordance with the limited land available at the Cahaya Alam Foundation. The planting medium uses polybags, and a simple screen house for organic vegetable nurseries. The output obtained from organic farming education is to provide assistance in the cultivation of organic vegetables at the demonstration plot, construction of screen houses and simple polybags, providing counseling, mentoring and learning to solve problems in cultivating organic vegetables and ornamental fl owers at the Cahaya Alam Foundation.

Gondangmanis guava production decreases every year, this is caused by pests and plant diseases, due to decreased soil quality, and soil fertility. In addition there are no good cultivation techniques so that Gondangmanis guava only grows conventionally. The purpose of this activity, for assistance, training and development of Gondangmanis guava picking tourism village. Implementation activities begin from April 2019 until August 2019, in Gondangmanis Village, kec. Bandar kedungmulyo, Jombang. The method used is a demonstration plot, and in-depth interviews. From the results of the assistance in this 3rd year, it can be concluded that there has been assistance, training and cultivation of Gondangmanis guava production. Community participation, especially those involved in guava development activities, and utilization of livestock waste is very high. Likewise, support from community leaders and village and district level officials was very supportive. Also pioneered the formation of tourism Gondangmanis guava village. The Guava Gondangmanis Community Group and the Tourism Awareness Group (POKDARWIS) have been formed. The role of the Department of Agriculture and Animal Husbandry and the Regional Government of Bappeda in Jombang Regency is also very high, because during the preparation and coordination process, it always receives attention from the leadership of the Regional Government, as evidenced by the formation of leading tourism in Jombang.

The decrease in productivity and degradation process in land cropped with cassava occurs very rapidly. A conventional soil conservation approach has been shown do not give satisfactory result. A new approach, which is termed "land husbandry", seems to have a more prospective future. Different from soil conservation approach, which is aimed to control erosion rate to level of less than acceptable limit erosion, the aim of land husbandry is to obtain a high yield and income. Secondly, in contrary with soil conservation approach where most of the technology package is developed based on and by researchers, in the land husbandry approach the development of technology is based on farmers' idea and willingness and done by the farmers themselves. The methodology used in this study was Farmers' Participatory Research. The study shows that the FPR methodology have promising prospect for developing the sustainable cassava production technology. The introduced technology spread up quickly and the adoption sustained for a long periods. After 5 years of the project, 65% of the farmers in the study area had planted UB 477-2 variety and 76% of the cassava farmers had use cattle manure for their cassava crops. Ten years after the project, in addition to UB 477-2 variety, some farmers planted another introduced variety i.e., Malang 6 and Markonah. The number of farmers using manure also increased substantially and some farmers practiced compost technology. At the beginning of the project there was no farmer planted UB 477-2 and only few farmers used cattle manure.
