Abstract

Analysis and identification of superior agricultural commodity areas play a crucial role in determining regions with high potential for agricultural development. This study aims to identify priority agricultural commodities and assess their development potential in Lawang, Matur District, Agam Regency, West Sumatra Province. The research was conducted in several stages. First, superior agricultural commodities were identified using the Location Quotient (LQ) and Shift Share Analysis (SSA) methods. Second, the potential development areas for these commodities were determined using the Analytical Hierarchy Process (AHP) and Weighted Linear Combination (WLC) approach, integrated with Geographic Information System (GIS) analysis. The results indicate that the priority agricultural commodities in Nagari Lawang are peanuts for the food crop subsector, shallots for the horticulture subsector, and sugarcane for the plantation subsector. These findings provide valuable information for policymakers and local farmers to optimize land use, enhance agricultural productivity, and support sustainable rural economic development. Furthemore, the methodology used in this study can also be applied to other regions to identify superior agricultural commodities.Keywords: Analytical hierarchy process, Leading commodities, Location quotient, Shift share analysis, Weight linear combination.

Abstract

Irrigation modernization is a solution proposed to achieve an effective, efficient, and sustainable participatory irrigation management system. The purpose of this study was to measure the value of irrigation modernization readiness (IKMI) and determine the priority order of the Batang Anai Irrigation Area (IA). The IKMI method used 5 criteria for irrigation modernization (reliability of water supply, water and irrigation resource facilities and infrastructure, management of water and irrigation resources systems, water and irrigation resource management institutions, and human resources) and determines the priority order for modernization preparation using the Fuzzy Analytical Hierarchy Process method. Direct observation activities were carried out for the pillars of irrigation infrastructure and water availability, while interviews and questionnaires were used to assess management systems, management institutions, and human resources. The IKMI value 67.50 for the Batang Anai IA implies modernization is postponed, and irrigation system improvements can be carried out for 1-2 years. The priority order for irrigation modernization is water availability, management institutions, irrigation management, irrigation infrastructure, and human resources. Recommended actions for modernization readiness include checking the water supply system, normalizing irrigation channels, repairing damaged irrigation infrastructure, increasing farmer participation through socialization and training activities, and building synergy between irrigation managers. Keywords: FAHP, IKMI, Irrigation, Modernization, Sustainability.

Abstract

Tujuan dari penelitian adalah menentukan tingkat kesesuaian lahan tanaman ubi kayu di Provinsi Sumatera Barat berbasis Growing Degree Days (GDD) secara spasial dan temporal. Parameter yang digunakan yaitu curah hujan, kelerengan, penggunaan lahan, tekstur tanah, dan pH tanah. Semua parameter dikelompokkan menjadi satu atribut dengan cara overlay menggunakan aplikasi ArcGIS, kemudian dilakukan pembandingan (matching) dengan syarat tumbuh tanaman ubi kayu untuk kesesuaian lahan, dan dilanjutkan dengan pemberian scoring. Analisis dilanjutkan dengan menentukan nilai Growing Degree Days (GDD) pada setiap titik pengamatan masing-masing skenario waktu tanam yang diolah menggunakan data suhu. Skenario waktu tanam yang digunakan pada penelitian ini sebanyak 12 skenario waktu tanam. Hasil penelitian menunjukkan Provinsi Sumatera Barat memiliki lahan yang potensial untuk pengembangan tanaman ubi kayu, kelas sangat sesuai (S1) seluas 879.921,97 Ha dan kelas sesuai (S2) seluas 1.437.152,41 (39,92%). Waktu tanam yang paling optimal untuk tanaman ubi kayu berdasarkan nilai GDD untuk wilayah Sumatera Barat yaitu pada bulan Oktober. Kabupaten Lima Puluh Kota, Pasaman, Pasaman Barat, Pesisir Selatan, dan Solok Selatan memiliki potensi yang tinggi untuk dilakukan pengembangan tanaman ubi kayu karena pada wilayah ini memiliki kecocokan pada lahan (sangat sesuai) S1 dan sesuai (S2) yang luas (> 200.000 ha), serta niai GDD wilayahnya sesuai dengan nilai GDD untuk ubi kayu.

Abstract

Plant factory with Artificial Lights (PFAL) merupakan tipe plant factory yang menggunakan LED (Light Emitting Diodes) sebagai sumber utama cahaya untuk mendukung pertumbuhan tanaman. Beberapa penelitian terdahulu umumnya hanya terfokus pada analisis pengaruh perbedaan intensitas cahaya atau lama penyinaran LED terhadap pertumbuhan dan perkembangan tanaman pada plant factory. Penelitian ini bertujuan untuk menganalisis pengaruh siklus fotoperiode terhadap pertumbuhan selada romaine yang ditanam pada sistem PFAL. Siklus fotoperiode yang diberikan pada penelitian ini perlakuan 1 (1 siklus, 14 jam terang/10 jam gelap), perlakuan 2 (2 siklus, 7 jam terang/5 jam gelap x 2) dan perlakuan 3 (4 siklus, 3,5 jam terang/2,5 jam gelap x 4). Siklus fotoperiode mempengaruhi pertumbuhan dan berat basah selada romaine, dimana perlakuan 1 dengan siklus fotoperiode yang lebih panjang memberikan hasil terbaik dengan rata-rata tinggi, panjang daun, lebar daun, jumlah daun dan berat basah masing-masing yaitu 21,46 cm, 17,69 cm, 9,72 cm, 12,73 helai dan 52,49 gram. Perlakuan 1 juga memberikan hasil rasio berat basah terhadap konsumsi energi listrik yang paling tinggi yaitu sebesar 28,05 gr/kWh sehingga perlakuan 1 lebih efisien dalam menghasilkan berat basah selada romaine per jumlah energi listrik yang digunakan dibandingkan dengan perlakuan 2 dan 3

Abstract

Climate change affects rainfall patterns, causing shifts in the onset of seasons that impact water resource availability, thereby disrupting crop growth, yields and agricultural production. Rainfall variability, both spatially and temporally, can lead to changes in the planting and harvesting seasons of crops, which in turn affect the food security of a region. The objectives of this study were to identify rainfall characteristics in Koto Tangah District, identify the rice planting season in Koto Tangah District, and analyze the effect of changes in rainfall characteristics on the rice planting season in Koto Tangah District. The research employs a combination of quantitative and qualitative methods, presented in a descriptive and explanatory manner. The analysis to observe changes in rainfall characteristics was conducted over three periods: quarterly, semi-annualiy, and annually. The rainfall characteristics analyzed were minimun, maximum, average and total rainfall. After analyzing rainfall characteristics, changes in rainfall characteristics were integrated with the rice planting season in Koto Tangah District, Padang City. Based on the analysis results, it was conducted that there were changes in rainfall characteristics in Koto Tangah District, Padang City, however farmers did not use rainfall as the primary reference for determining the rice planting time. Koto Tangah District already has a good technical irrigation network, enabling it to provide water for rice fields throughout the year. In addition to being supported by good technical irrigation, Koto Tangah District has relatively high rainfall every year. Therefore, changes in rainfall characteristics do not affect the rice planting season in Koto Tangah District.
