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

Mung bean (Vigna radiate L.) is one of the most widely cultivated crops after soybean and peanut. Mung beans (Vigna radiate L.) became one of the crops that experienced a decline in production amid the increase in the area of harvested land in West Sumatra. The purpose of this study was to analyze the level of land suitability of mung bean crops using the Growing Degree Days method in West Sumatra Province. The research method used in this research is Scoring and Overlay using ArcGis 10.5 software. Land suitability analysis is carried out by giving scores to several parameters of land characteristics. The parameters used are slope, land use, rainfall, soil texture and soil pH. Growing Degree Days analysis was conducted by accumulating the daily temperature values of plants based on planting scenarios. These two analyses were combined with Overlay clustering. The results showed that the land area of West Sumatra whose GDD value is optimal for mung bean growth with the level of land suitability in physical characteristics in S1 class is 15,819.29 ha and in S2 class is 877,501.06 ha. Areas that are suitable in terms of physical characteristics and values with an area of > 100 ha are Lima Puluh Kota District, Pasaman District, Solok District, and South Solok District. The best planting time for mung bean based on the planting scenario is from December to March.

Abstract

Agriculture is a major contributor to non-point source pollution due to the intensive use of agrochemicals. This study examined the spatial distribution of pollutants from agricultural activities in the Sumani sub-catchment, West Sumatra, Indonesia, which drains into Lake Singkarak. Thirteen water quality parameters were measured, including electrical conductivity (EC), total suspended solids (TSS), total dissolved solids (TDS), dissolved oxygen (DO), sulfate, nitrate, calcium, sodium, total phosphorus (TP), potassium, magnesium, chlorpyrifos, and mancozeb. Results showed significant variation in water quality across the sampling sites. Downstream areas had higher levels of TSS, TDS, and major ions, mainly due to agricultural and urban activities. The lowest TSS levels were recorded at a site within the lake, likely due to sediment settling. River water generally met drinking water standards; however, TP and DO concentrations in the lake exceeded regulatory limits, potentially influenced by floating net cage aquaculture. Principal Component Analysis identified three main sources of pollution: agricultural activities (34.87%), combined agricultural and urban influences (20.15%), and soil erosion (12.15%). These findings highlight the need for better erosion control, sustainable farming practices, and consistent water quality monitoring. Further research is crucial to understand the long-term effects of agriculture on water resources and to develop strategies that reduce environmental impacts.

Abstract

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

Abstract

Peanuts are one of the leading commodities of Nagari Tigo Balai, Matur District, Agam Regency, West Sumatra. Some people in Nagari Tigo Balai have processed peanuts into rendang peanuts and many still sell their raw peanuts directly from their harvest. The processed peanuts from Nagari Tigo Balai craftsmen are still packaged in ordinary packaging, namely using transparent plastic and makeshift labels. This activity aims to provide assistance to the peanut MSMEs of Nagari Tigo Balai to produce packaging according to the target market. This activity is carried out in several stages, namely socialization, packaging design, and assistance in the use of packaging. One of the productive peanut MSMEs in Nagari Tigo Balai is the LBM MSMEs. The assistance activity has produced three packaging designs, namely the PP standing pouch packaging design, the PP plastic packaging sticker label design, and the PP plastic packaging screen printing label design. The most suitable and needed packaging design for the rending peanut craftsmen of LBM MSME Nagari Tigo Balai is the sticker label on PP plastic packaging. The chosen design is consistent with the target market of rendang peanuts produced by LBM MSME Nagari Tigo Balai, which includes consignment system at souvenir outlets, direct sales in nearby markets, and distribution through local traders.

Abstract

Pertumbuhan dan hasil tanaman ditentukan oleh beberapa faktor utama yang terdiri dari tanah, iklim, dan tanaman. Pengaruh iklim terhadap pertumbuhan tanaman jauh lebih besar daripada tanah pada kondisi tertentu. Hal ini dibuktikan oleh beberapa kondisi dimana pertumbuhan vegetasi penutup yang jauh berbeda padahal tumbuh pada tanah yang sama. Waktu panen satu jenis tanaman tidak sama pada setiap tempat yang berbeda. Hal tersebut dipengaruhi oleh salah satu faktor penting yaitu derajat tumbuh harian atau derajat hari pertumbuhan Growing Degree Days (GDD). Kesesuaian wilayah untuk perkembangan suatu komoditas pertanian dapat ditentukan dengan mengetahui parameter-parameter seperti jenis tanah, kelerengan, penggunaan lahan, curah hujan, dan suhu GDD dengan menggunakan sistem informasi geografis. Penelitian bertujuan untuk menentukan kesesuaian lahan tanaman kedelai wilayah Sumatera Barat berdasarkan nilai GDD. Analisis kesesuaian lahan menggunakan metode GDD dilakukan melalui beberapa tahapan yaitu klasifikasi parameter kesesuaian lahan tanaman kedelai, pembuatan peta kesesuaian lahan tanaman kedelai secara karateristik fisik, klasifikasi nilai GDD tanaman kedelai untuk wilayah Sumatera Barat, pembuatan peta kesesuaian lahan tanaman kedelai berdasarkan nilai GDD. Lahan potensial untuk budidaya kedelai di Sumatera Barat berdasarkan kelas kesesuaian lahan, karakteristik fisik dan nilai GDD yaitu seluas 555.791,66 hektar pada kelas S1 (sangat sesuai) dan seluas 2.313.796,44 hektar pada kelas S2 (cukup sesuai). Waktu tanam yang paling optimal untuk budidaya kedelai adalah pada bulan Agustus. Kabupaten Lima Puluh Kota, Kabupaten Pasaman, Kabupaten Sijunjung, dan Kabupaten Solok memiliki lahan yang cocok untuk budidaya kedelai dengan luas lebih dari 200 ribu hektar dan berada pada daerah dengan Growing Degree Days yang sesuai bagi pertumbuhan kedelai.

Abstract

Drought analysis can be used as an early warning of drought in rice fields, which can be identified by connecting various parameters. This study aims to identify the potential for rice fields vulnerable to drought in Agam Regency. Drought is primarily caused by uneven rainfall distribution, leading to imbalanced hydrological conditions. This study used the last 30 years of rainfall data (1993 2022) from five stations located at Agam Regency (Canduang and Gumarang) and the rest outside of the study area (Padang Panjang, Suliki, and Paraman Talang). Spatial analysis of drought distribution was carried out using the Inverse Distance Weighted (IDW) method. The results showed the consistency test value of rainfall data for all five stations was obtained with an average of R² with a value of 0.992, the potential area of rice fields with a dry and very dry category was 13,640.61 ha and 904.55 ha, respectively. The conclusions of this study are (i) the districts with the most potential to be affected by drought (dry and very dry categories) are Tilatang Kamang and Malalak District, with an area of 2,058.15 ha and 750.48 ha, respectively, (ii) it is important to prepare the water shortage in the dry season by utilizing rivers, irrigation and reservoirs in the area. Keywords: Agam Regency, Drought Potential, Rain, Rice Fields, SPI.

Abstract

Nagari Lawang is located in Agam Regency, West Sumatra, which is a nagari situated in the highlands with a slightly steep to very steep slope with the most types of land use in moors/fields. This can directly encourage erosion. This study aims to analyze the optimal land use pattern for reducing the rate of erosion in Nagari Lawang. The method used to calculate the erosion rate is the Universal Soil Loss Equation (USLE) and to obtain the optimal land use in reducing the erosion rate is a simulation with three scenarios. The results of the study showed that 47.29% of the Nagari Lawang land area was at an erosion rate above the tolerance erosion with the category of light to very heavy. Based on land use simulations, planning scenario III by allocating the use of shrubland into mixed gardens with planting according to contour lines and the use of shrub land into mixed forests is the best scenario because it can reduce erosion by 39.05% of the total erosion of Nagari Lawang. The reduction of erosion on the diverted land (moors/fields and shrubs) reached 45.83% of the existing condition, which was 2105.928 tons/ha/year. The best scenario land use can be used as a reference by policy makers and the community in determining appropriate land management actions in Nagari Lawang. Keywords: Erosion, Simulation, Land Use, USLE.
