Abstract

Indonesia is recently facing the fertilizer issue as the shortage supply of subsidized fertilizers is aligned with the increasing price of non-subsidized ones. So, it eventually resulted in the unstable price of agricultural commodities. The issue has been becoming an obstacle for farmers practising agricultural cultivation, particularly those in Batang Tajongkek Village, Pariaman, West Sumatra Province. It needs to develop its potential for natural resources to make organic fertilizer from cow manure. Furthermore, the solution supports the government program on establishing integrated agriculture. Two activities were conducted to empower the area's potentials, which were counselling and composting demos, respectively. The aim was to ensure knowledge transfer to the farmers regarding the technology and critical method of cow manure composting. During the counselling, the farmers were facilitated to discuss the related issue of sustainable integrated agriculture, organic farming, and the making process of compost. Meanwhile, the process of composting from cow manure was also shown during the demo. Furthermore, the farmer was facilitated to analyze the content of produced compost, which was mainly focused on the content of nitrogen (N), phosphorous (P), and potassium (K). The activities have empowered the people in the area to self-produce cow manure compost as an organic fertilizer. The analysis of the produced compost showed that the compost has yet to fulfil the national standard of solid fertilizer (SNI 7763:2018) regarding the content of macronutrients (N + P2O5 + K2O). However, the pH of produced compost has met the national standard. The pH was 7.27, which ranges from 4-9. For the compost to be utilized by the community, it is necessary to mix other materials in its manufacture so that the resulting compost complies with SNI.

Abstract

AbstractObservation of the growth phase of rice plants generally takes a long time and cannot cover a large area. With remote sensing, the speed and accuracy of information in agricultural management is easier. The use of MODIS satellite image data in remote sensing technology plays a role in determining the growth phase of rice plants by utilizing the vegetation index value of rice plants. The aim of the study was to determine the regression equation and the range of NDVI (Normalized Difference Vegetation Index) values to predict the growth phase of rice plants in Harau District, Lima Puluh Kota District. Research in the field was carried out based on work maps obtained from the results of the imaging process in ArcGis. The location used as a sample of field observations is Grid ≥45% which is occupied by rice fields. Regression analysis was carried out to obtain a regression equation between plant age and NDVI values, then a range of values was made based on the rice growing phase. The regression equation used to predict the growth phase of rice plants in Harau District based on the NDVI value is y = -0.0000838932x² + 0.0123160507x + 0.2966130658 where x is the age of the plant (days after planting) and y is the NDVI value. The correlation coefficient (r) of the regression equation is 0.966. The range of NDVI values based on the growth phase for Harau District is the Water Phase 0.4722, the Vegetative Phase (1) 0.4722-0.6945; Vegetative phase (2) 0.6945-0.7412; Generative phase (1) 0.7412-0.6363; Generative phase (2) 0.6363-0.5665; Bera 0.5665-0.4799.Keywords:: growth phase; vegetation index; MODIS; NDVIAbstrakPengamatan fase pertumbuhan tanaman padi pada umumnya membutuhkan waktu yang lama dan tidak bisa menjangkau area yang luas. Dengan penginderaan jauh, maka kecepatan dan ketepatan informasi dalam pengelolaan pertanian lebih mudah. Penggunaan data citra satelit MODIS pada teknologi penginderaan jauh berperan dalam menentukan fase tumbuh tanaman padi dengan memnafaatkan nilai indeks vegetasi dari tanaman padi. Tujuan penelitian adalah menentukan persamaan regresi dan rentang nilai NDVI (Normalized Difference Vegetation Index) untuk memprediksi fase tumbuh tanaman padi di Kecamatan Harau Kabupaten Lima Puluh Kota. Penelitian di lapangan dilakukan berdasarkan peta kerja yang diperoleh dari hasil proses pencitraan pada ArcGis. Lokasi yang dijadikan sampel observasi lapangan adalah Grid ≥45% yang ditempati oleh sawah. Analisis regresi dilakukan untuk mendapatkan persamaan regresi antara umur tanaman dan nilai NDVI, kemudian dibuat rentang nilai berdasarkan fase tumbuh padi. Persamaan regresi yang digunakan untuk memprediksi fase tumbuh tanaman padi di Kecamatan Harau adalah y = -0,0000838932x² + 0,0123160507x + 0,2966130658 dengan x sebagai umur tanaman (hari setelah tanam) dan y sebagai nilai NDVI. Koefisien korelasi (r) dari persamaan regresi adalah 0,966.  Rentang nilai NDVI berdasarkan fase tumbuh untuk Kecamatan Harau adalah Fase Air 0,4722, Fase Vegetatif (1) 0,4722-0,6945; Fase vegetatif (2) 0,6945-0,7412; Fase generatif (1) 0,7412-0,6363; Fase generatif (2) 0,6363-0,5665; Bera 0,5665-0,4799.

Abstract

The factors influencing shallot production include the soil nutrient content. Efforts to increase shallot production can be achieved through optimal fertilizer usage. The use of inorganic fertilizers can disrupt the biological ecosystem balance of the soil. To address this, the utilization of organic fertilizers becomes essential as they are more environmentally friendly and utilize existing waste. Nagari Palangki, known for having the largest livestock market in West Sumatra, generally has a substantial number of livestock owners, thus having significant potential in providing organic fertilizer. The availability of organic fertilizer should support agricultural activities, especially shallot cultivation, in Nagari Palangki. Based on this premise, it's crucial to conduct education among the community regarding the utilization of organic fertilizer in shallot cultivation in Nagari Palangki. The activity aims to transfer knowledge to the community to enhance shallot production in Nagari Palangki, IV Nagari District, Sijunjung Regency. The target audience comprises the community involved in shallot cultivation. The implementation of activities related to the use of organic fertilizers in shallot cultivation in Nagari Palangki has been completed. The farming community responded positively to the knowledge transfer, with farmers even applying the materials given to their land. Furthermore, the waste from the livestock market in Nagari Palangki, IV Nagari District, Sijunjung Regency, holds substantial potential and supports the success of the shallot cultivation encouraged by the local government of Nagari Palangki.
