Chili plants (Capsicum Annum L.) requires the availability of water in sufficient quantities and timely. The situation can be achieved by the application of drip irrigation system. This is due to the system can set the amount and timing in accordance with the water requirements of chili plants. This research was conducted in Nagari Biaro, District Ampek Angkek, Agam regency which aims to design a drip irrigation system that is suitable and appropriate for chili cultivation in the greenhouse. In this study, observations were conducted to the evapotranspiration of chili (ETC), technical testing, and feasibility analysis of drip irrigation systems. Based on the research results, highest ETc of 2.16 mm/day was occurred in the period from the beginning of the generative phase, with an average discharge droplets of 137.685 mm3/sec, the system operated for 0.84 hours/day to meet the water needs of chili plants. However, by considering the three parameters of technical feasibility, the system is still not feasible because there was only one that fits the required value, namely the distribution efficiency (91.49%). The uniformity (76.97%) and irrigation efficiency (74.37%) have not yet reached the minimum required value of 90%, this is caused by differences in head and the length of each channel, thus the pressure on the line was not uniform which causing varied discharge droplets.

The concept of food sovereignty has officially become the goal and approach in national food development, as stated in Law no. 18 of 2012 concerning Food, food independence and food security. This activity aimed to provide an overview of the concept of food sovereignty that the community can carry out through the Agroecology Field School. The results from the field school show that food sovereignty was an essential strategy to complement food security as the ultimate goal of food development so that people can be independent without any dependence. Agroecology field school activities emphasize that food sovereignty relates to farmers' rights and access to all agricultural resources, including land, water, production facilities, technology, marketing, and consumption. This condition can be measured at various levels at the individual, household, community and regional levels. The agroecology field school activities were held in two locations: Lubuk Gadang Selatan and Sako Utara Pasia Talang, West Sumatra. The material presented at the extension activity includes Introduction to Agricultural Science, Agroecology, Basics of Agricultural Ecosystems, Food Sovereignty, Cultivation and Breeding Techniques, Plant Maintenance, Fundamentals of Soil Science, Irrigation Management, Plant Breeding and Post Harvest.

The affirmation of village boundaries is the process of determining the coordinates of the boundaries, which can be carried out using cartometric methods and surveys in the field. It is outlined as a boundary map for village boundaries coordinate points as agreed. The determination of affirmation generally consists of three stages: collecting and researching boundary documents, determining a base map, and making a cartometric map of village boundaries. This activity aimed to determine boundary segments, objects, cartometric points, and artificial pillars for determining and confirming the boundaries of Pasir Binjai Village, Silaut District, and Pesisir Selatan Regency. The results of this activity were 1) Pasir Binjai Village has five boundary segments, all segments bordering the border villages within one administrative area of the Silaut District government; 2) Natural boundaries, namely mark village boundary objects: river flow or middle of the river, middle of drainage or ditch, a centre of the road, and some are found on community plantation land; 3) the total number of cartometric points as a reference and the village boundary nodes are 15 points; 4) the number of pillars made for the artificial marking of the village boundaries are six pillars, there are four boundary pillars which are the primary boundary reference pillars which are not located right on the boundary line, and two boundary pillars are the main boundary pillars which are located right on the boundary line.

Each region has its own cropping pattern due to its particular characteristics. Crop production may be increased by adjusting the timing of planting. Remote sensing technologies can be used to monitor regions where planting occurs simultaneously. The purpose of this study is to assess the degree of uniformity at the beginning of the paddy cultivation season in West Sumatra. In each growing season, there are two early cultivation seasons in the West Sumatra province. 19% of the region started cultivation in the first period of the first cultivation season (CS1), and 81% in the second period. 4.2% of the region started cultivation in the first period of the second cultivation season (CS2), while 95.8% started planting in the second period. 35% of the region started planting in the first period of the third cultivation season (CS3), while 65% started planting in the second period. The level of uniformity at the beginning of the second cultivation season was higher than at the beginning of the first cultivation season

The calculation of crop productivity has now been facilitated by technological development using remote sensing technology or data generated by satellites. Determining the value of productivity using images will shorten the time and does not require much effort. A remote sensing model that connects satellite image reflectance data with rice plant parameters will be handy for monitoring biomass growth and predicting crop yields more quickly and efficiently. This study aimed to determine the regression equation to estimate the productivity of regional rice in Harau District, Lima Puluh Kota Regency. This study consisted of several stages: data collection, data processing, and calculation of rice productivity, NDVI regression analysis with rice productivity, and Nash-Sutcliffe Efficiency (NSE) test against the obtained equations. The regression equation obtained from the results of data analysis to estimate rice productivity in Harau District, Lima Puluh Kota Regency is y = - 82152x4 + 208465x3 - 197654x2 + 82986x - 13014, with an NSE value of 0.64 which is categorized as ‘sufficient’.Keywords: MODIS, NDVI, Rice, Remote sensing; Productivity

Pada daerah yang luas biasanya terdapat kesulitan dalam memantau fase tumbuh tanaman padi. Seiring dengan berkembangnya teknologi, salah satu alternatif yang dapat dilakukan untuk memperoleh data tersebut adalah dengan menggunakan citra satelit. Fase tumbuh tanaman padi dapat diketahui dengan menghitung indeks vegetasi berdasarkan tingkat kehijauan tanaman dengan bantuan citra MODIS menggunakan algoritma NDVI. Tujuan dari penelitian ini adalah menentukan persamaan dan rentang nilai NDVI untuk memprediksi tahap pertumbuhan padi di Kecamatan Sungai Tarab Kabupaten Tanah Datar. Dalam pengambilan data, pengamatan lapangan dilakukan pada lokasi dengan pixel ≥50% adalah sawah. Pengamatan dilakukan untuk validasi koordinat lokasi sampel pengamtan, kesesuaian data penggunaan lahan, umur tanaman padi, dan varietas padi. Dari hasil analisis, persamaan yang diperoleh untuk memprediksi fase tumbuh tanaman padi Kecamatan Sungai Tarab yaitu y = -0.0001011274 x2 + 0.0128987956 x + 0.3189628155 dimana nilai x adalah umur tanaman (HST) dan y adalah nilai indeks vegetasi (NDVI). Rentang nilai NDVI berdasarkan fase tumbuh adalah fase air ≤ 0,4797; fase vegetatif 1 0,4797-0,6149; fase vegetatif 2 0,6149-0,7300; fase generatif 1 0,7300-0,6379; fase generatif 2 0,6379-0,5142 dan fase bera 0,5142-0,2868

Rice productivity is closely related to rice harvested area and cropping intensity. Remote sensing technology using MODIS MOD13A1 v006 image produces Normalized Difference Vegetation Index (NDVI) values that can be interpreted in analyzing the value of rice productivity. Gunung Talang District has a rice field area of 3,369 m2, which is one of the central rice areas in West Sumatra Province. This study aimed to determine the regression equation to estimate rice productivity in Gunung Talang District, Solok Regency using the NDVI algorithm. The NDVI data used to generate the regression equation was taken in the generative phase. From the results of data analysis, the regression equation for estimating rice productivity in Talang District, Solok Regency is y = 250.33x4 - 1493.3x3 + 2293.6x2 - 1353.9x + 281.13, where x is the NDVI value and y is the productivity value (ton ha-1). The test results of the model's validity are expressed in the value of NSE (Nash-Sutcliffe Efficiency) is 0.66, which is categorized as adequate.
