The result of this research is the creation of a web-based GIS application that can present information about the location of accident-prone areas in West Sumatra in detail and can be accessed easily be used people.

West Pasaman District and Agam District are filariasis-endemic areas in West Sumatra with prevalence of 12.40 per 100,000 cases and 11.27 per 100,000 cases respectively. This study aimed to determine risk factors associated with the prevalence of filariasis and mapping the vulnerability of the area in West Sumatra. A case control study design was conducted in the West Pasaman District and Agam District. The study used a sample of 74 cases and 74 controls taken by simple random sampling for the case and purposive random sampling for control. Data analysis used univariate, bivariate, multivariate and spatial. The results in Agam District showed that variables associated relation with filariasis (p value < 0.05) were the level of knowledge, plantations, the paddy, the ceiling of the house. The most dominant risk factor was knowledge. Type of vector that was found was Culex. While in West Pasaman District, the variable associated with filariasis (p value < 0.05) was the use of mosquito nets, the habit of dressing, marshes, and ceiling. The most dominant risk factor was the ceiling of the house.

This study resulted in the effect of social capital, entrepreneurial experience and knowledge on entrepreneurial resilience. West Sumatra is one of the disaster-prone areas in Indonesia, so it is necessary to examine whether social capital, entrepreneurial experience and knowledge have an influence on entrepreneurial resilience with the case of food SMEs. We need to do this research to find out whether in disaster areas social capital, experience and knowledge contribute to creating entrepreneurial resilience. This study used 384 samples of food SMEs spread over 5 disaster areas in West Sumatra. Data were collected using a questionnaire which was processed using the SPSS tool with the questionnaire measurement scale being the Likert scale. The unit of analysis is the owner of food SMEs in West Sumatra specifically in disaster areas. By collecting as many as 384 respondents it is believed to be representative because the number of food MSMEs is definitely not contained in any information because it is rapidly growing. The results of the study reveal that the variables of social capital, entrepreneurial experience and knowledge have an effect on entrepreneurial resilience by 43.4%, while the rest are influenced by other variables that have not been taken into account in this study. Further research can be done by including other variables such as business performance, or entrepreneurial orientation.

This study was conducted to look at developing of ruminant and poultry population in agribusiness area in West Sumatra . The research method was used a literature study of farm statistics in 2011. Data analysis was done by descriptive qualitative agribusiness areas in West Sumatra with livestock population data Regency/City in West Sumatra 2011 and the results were depicted through graphs . The results showed that the area of agribusiness farms that had been established by the government of West Sumatra there were several areas of the district / city that was also the potential to served the agribusiness area not included in the region and vice versa. West Sumatra province had considerable potential for the development of both ruminant and poultry. Ruminant such as beef cattle was very good to be developed in the Pesisir Selatan, Padang Pariaman and 50 Kota with a population of respectively 23 % and 10 % of the total cattle population was in West Sumatra. Buffalo potential to be developed in Agam, Padang Pariaman, and Sijunjung . Types of poultry chicken laying and broiler with the largest number of population was 5,867,890 and 4,796,490 tails tails were in Limapuluh Kota which was the production center for the cattle.

The purpose of this study was to determine whether larval Ae. albopictus inhabiting Phytotelmata is a potential transmitter of Dengue Hemorrhagic Fever (DHF). The results concluded that Ae.albopictus larvae which inhabited Phytotelmata positively contained two serotypes of dengue virus (DEN-1) and (DEN-4) which has the potential to transmit and spread DHF.

Abstract. Noverita, Ratnaningtyas INI, Hernayanti, Ekowati N, Lestari S. 2025. Exploration and selection of native macrofungi with heavy metal tolerance for bioremediation in Jakarta Bay, Indonesia. Biodiversitas 26: 1940-1955. The increasing pollution of heavy metals Pb and Cd in Jakarta Bay poses a potential threat to marine biota, endangering human health. Macrofungi, known for their ability to mitigate heavy metal pollution through biosorption, are the focus of this research. The study aimed to collect macrofungi from West Sumatra Forest, selectively identifying species that are adaptive to salinity and heavy metals Pb and Cd, possessing a high Heavy Metal Tolerance Index (IT). Field exploration was conducted using a roaming method across 5 forest areas in West Sumatra, followed by laboratory cultivation and systematic screening. A descriptive analysis of fungal exploration data based on morphological characteristics was conducted. Selection results, measured by colony surface area on various treatment media (PDA, PDA with seawater, PDA with Pb/Cd, and PDA with seawater and Pb/Cd), and IT data were analyzed descriptively using GraphPad version 8 heatmaps. This study found that 94 macrofungal species were successfully isolated from 5 forest areas in West Sumatra, comprising 92 species from Basidiomycota and 2 species from Ascomycota. All isolated species demonstrated the capability to grow on various selection media, with varying degrees of adaptation. Nine species, including Coprinus comatus, Favolus tenuiculus, Ganoderma applanatum, Lepiota ristata, Marasmius sp. 21, Polyporus badius, Polyporus elegans, Polyporus sp., and Trametes cubensis, exhibited optimal growth on all media. Statistical analysis with ANOVA (Analysis of Variance) revealed that four species C. comatus, P. elegans, Marasmius sp. 21, and F. tenuiculus, consistently showed superior performance across all test conditions. The Heavy Metal Tolerance Index for Pb and Cd across all species was excellent, with 74% classified as very high, 22% as high, and 4% as moderate. These findings suggest significant potential for utilizing these fungal species in marine bioremediation applications.

Hasmiwati, Supargiyono. 2018. Short Communication: Genotyping of kdr allele in insecticide resistant-Aedes aegypti populations from West Sumatra, Indonesia. Biodiversitas 19: 552-558. Aedes aegypti, the primary vector of Dengue fever, is widely distributed in Indonesia including in West Sumatra. Chemical insecticide is an effective way of shedding the chain of Dengue fever transmission. Long-term applications of insecticides have resulted in the development of resistance in Ae. aegypti populations. Knockdown resistance (kdr) allele as a result of point mutations has been found in Voltage-Gated Sodium Channel (VGSC) gene. This study aimed to design allele-specific primers to detect the kdr allele mutations. Ae aegypti samples were collected from several dengue endemic areas in West Sumatra. The susceptibility of adult mosquitos to insecticides was determined by bioassays using impregnation paper test with 0.18% malathion and 0.75% permethrin. In this study, we successfully confirmed that the A. populations have point mutations in the VGSC gene corresponding to S989P and V1016G amino acid substitutions. To genotype S989P and V1016G alleles, we designed kdr allele-specific primers based on the sequence of VGSC gene (NCBI Accession number No. EU399179.1. PCR analysis using the kdr allele-specific primers successfully identified the genotype of Ae. aegypti populations resistant to malathion and permethrin in West Sumatra.

Indonesia is a rich and beautiful country to natural tourism destinations, one of which is the area of West Sumatra. West Sumatra belongs to the four categories of Kompetisi Pariwisata Halal Nasional . West Sumatra has tremendous potential for the development of halal tourism sector, which will affect the economic growth of the community. The purpose of this paper is to know the prospects of halal tourism destinations in West Sumatra. The study is at Pagaruyung Palace. Review the concept of one village, one product. In this concept each region has and develops its own uniqueness that is not owned by other regions. With this difference will later add tourists who come. Through this concept in the future can create an independent society. West Sumatra can be used as a model or example for other areas in the management and development of halal tourism.

The purpose of this study is to analyze and classify the level of competitiveness of districts/cities in West Sumatra. This research uses secondary data sourced from the Central Statistics Agency (BPS) and the National Research and Innovation Agency (BRIN) for 2022-2023. This research uses RCI (The European Regional Competitiveness Index) calculation and Klassen Typology analysis. Based on the research results, it is found that each pillar supports each other and is closely related to economic growth. Some areas in West Sumatra, especially remote areas such as Mentawai Islands, suffer from lack of infrastructure such as roads, electricity, and public facilities. Major cities such as Padang are often the center of infrastructure development, while other districts are given less attention. There is a disparity in macroeconomic stability among districts and cities in West Sumatra.

West Sumatra was declared as a center for Indonesian cocoa in the western portion. Almost all areas in West Sumatra are suitable for cocoa cultivation, so the cocoa planting area covers almost all the districts in the province. However, West Sumatran Cocoa production decline occurs because cocoa plantations are still mostly cultivated with smallholder plantations. The occurrence of land conversion and reduced land carrying capacity, including soil fertility, is due to the continuous use of inorganic fertilizers, which results in a decrease in the ecological quality of the land. Efforts to improve land conditions biologically by utilizing soil biotechnology. One of the soil microbes that can be utilized is Arbuscular Mycorrhizal Fungi (AMF). AMF that live in a symbiotic mutualism with plant roots and helps the absorption of plant nutrients and live in various places. The study aimed to identify arbuscular mycorrhiza Cocoa rhizosphere three districts, West Sumatra province, from the month of November 2020 to May 2021. The results showed the number of spores and diversity of AMF. The number of spores was 67-218 spores per 20 g soil. The root colonization was in the range of 21.3 - 24.6%. While the AMF diversity before trapped found three types of sport Glomus sp., Acaulospora sp., dan Gigaspora sp

Rendang is one of traditional food of Minangkabau society, West Sumatera which has unique flavor and aroma. The characteristic of rendang is the umami taste which is a mixture of salty, sweet and spicy flavor that harmonizes with each other. The main ingredients in the manufacture of rendang are meat, coconut milk, and spices. Spices used in rendang are red chili, red onion, garlic, turmeric, galangal, coriander, lemongrass, ginger, candlenut, bay leaf, turmeric leaves and orange leaves. The use of these spices can improve the aroma and distinctive taste of rendang. The purpose of this study was to identify the sensory characteristics of rendang products from various regions in West Sumatra. The method used to analyze rendang sensory characteristics is Quantitative Descriptive Analysis (QDA) which uses trained panelists on the test. QDA consist of panelist training, Focus Group Discussion (FGD) and sensory testing of rendang products. There are 11 attributes identified by the panelists on rendang are obtained from FGD, they are blackish color and aroma (oil, roasted coconut, umami, aroma of meat and smoke), and taste (sweet, salty, spicy, umami and bitter). The results of QDA test were analyzed using Principal Component Analysis (PCA). The PCA identified four major components that accounted for 99.3% of the variation of sensory data. Sensory profiling shows the correlation between each attribute and the sample of rendang indicating that the rendang is spread over four quadrants. Rendang from Bukittinggi is found in the first quadrant and characterized by the aroma of fishy, the taste of salt and sweet. Rendang from Pariaman, Sawahlunto, and Tanah Datar / Batusangkar are found in the second quadrant characterized by umami aroma, spicy flavors, umami taste and aroma of the oil. Rendang from Padang is in the third quadrant and characterized by the aroma of roasted coconut and black color. Rendang from Payakumbuh contained in the fourth quadrant characterized by the aroma of smoke and bitter taste. Based on the evaluation of sensory characteristics performed using PCA, it can be concluded that the new sensory characteristics (the result of a reduction of eleven sensory attributes analyzed) on rendang products in various areas in West Sumatra can be distinguished by four attributes: aroma, cooking time, spices and flavors. This is the first systematic study on profiling of sensory attributes of rending using a standard sensory method.

The Laku Pandai policy that has been issued by the Government is expected to increase the level of financial inclusion and literacy in Indonesia. However, not many realize that the Laku Pandai policy also has a further impact on local economic development in the region. Therefore, this study aims to analyze Laku Pandai's policy on local economic development in West Sumatra. This study was designed using a qualitative method with a descriptive approach. The source of the data used is from interviews with Laku Pandai agents, in this case BRILink agents in Padang City and Solok Regency as representatives of urban, sub-urban and rural areas in West Sumatra. The results show that the Laku Pandai policy issued by the government has an influence on local economic development, especially in West Sumatra. This can be seen from the important role of local economic development that can be seen after the implementation of the BRIlink Agent began in 2016. Important roles that can be seen and felt such as increasing business opportunities, employment, business retention, economic diversification, self-sufficiency, increasing the tax base from the world business and society, quality of life, recognition of local products, and increased competitiveness. All of these important roles are certainly not only felt by BRILink agents, but also by all parties and layers in the area where the agent is located.

Yellow leaf virus disease, accompanied by vector insect attacks, was the leading cause of the current decline in eggplant production. Yellow leaf virus disease spreads more quickly due to the influence of insect vectors. The research aims to determine the type of insect vector that spreads yellow leaf virus disease and the incidence and severity of yellow leaf virus disease on eggplants in West Sumatra. This research method uses a survey method for five months in 2023. The sample was taken diagonally with five observation points. At each point, five plant samples were taken randomly. Observations were carried out three times at four locations representing the centers of eggplant production areas in West Sumatra, namely in Kuranji District, Pauh District, Batang Anai District, and Sitoga District. Five different vector insect species were discovered, along with their corresponding population sizes, according to the observations: Bemisia tabaci (5846 individuals), Amrasca sp. (1199 individuals), Thrips sp. (176 individuals), Paracoccus sp. (43 individuals), and Aphids gosypii (34 individuals). The incidence of the disease reached 90% with the severity of the disease being 42.45% in Sitoga District. The highest disease severity was 43.94% in Kuranji District, with an incidence of the disease of 70%. This research helps implement strategies to control yellow leaf virus disease by determining the threshold for the influence of the number of vector insect populations in increasing the incidence and severity of yellow leaf virus disease in eggplants.
