Study of yellow leaf virus disease on eggplant (Solanum melongena L.) in West Sumatra

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.

Accessibility Towards West Sumatra Tourism Area

Accessibility was identified as the main factor driving tourist travel. The transportation sector is one of the strategic elements in tourism. Transportation in tourism is a means to achieve tourist destinations and also a means of movement in tourist destinations. Transportation is one of the important indicators in the development of tourist destinations and the selection of destinations by tourists. West Sumatra Province is one of the provinces in Indonesia which is rich in tourist attractions and is also one of the tourist destinations that is quite taken into account not only at the national level but also at the international level. West Sumatra has been designated as one of the main national tourist destinations. This research identifies accessibility to existing tourist areas in West Sumatra and analyzes areas that have the highest and lowest accessibility and explains the existing condition of the availability of public transportation to provide services in terms of providing good accessibility to the tourist zone. This research uses a quantitative approach method to present numerical data through the normal distribution method to make each accessibility parameter into three classifications namely low, medium, and high, and also uses a qualitative approach that aims to investigate, describe and explain the existing conditions of transportation facilities to tourist zone which is the object of research using primary data. Through a qualitative approach, a detailed description of the condition of the availability of routes and public transportation will be produced which will be analyzed based on the results of mapping in the study area.

Penggunaan Data SPT dalam Penentuan Potensi Likuifaksi di Kota Solok

The area of West Sumatra which is at the confluence of 2 tectonic plates and 2 faults makes the area prone to earthquakes. One of the cities that has experienced an earthquake is Solok. One of the impacts of earthquakes is liquefaction events, namely the loss of strength of the sand layer due to increased pore water pressure. So that in planning construction in Solok it is necessary to review the potential for liquefaction in order to reduce construction damage and prevent liquefaction. To find out the potential for liquefaction as expressed by the value of the safety factor, it can be analyzed using standard penetration test data, namely N-SPT. The safety factor used in this study is the probability of 500 years and 2500 years. The results of the analysis of the safety factor obtained show that at each depth of the soil layer under review it has a value of < 1 so that the potential for liquefaction is quite high. The lowest safety factor is obtained at a depth of 4 – 6 m for a 500 year probability and 6 -7 m for a 2500 year probability which ranges from 0,12 – 0,16.

This can be used as an evacuation site, so the main thing that must be done is the maintenance of the sanitary condition of the mosque so that it is maintained and can become a proper evacuation site.

Identification Of Changes In Magnetic Clay Mineral Lattice Due To Batik Fabric Dyeing Process Using X-Ray Diffraction

<p class="AbstractText"><span lang="EN-AU">Clay in West Sumatra has been developed as an industrial material, one of which is a natural dye for batik. The use of clay as a natural dye was previously known to have magnetic minerals contained in clay so as to produce color and resistance to fabrics. Currently, no one has investigated the types of magnetic minerals found in clay and their effect on color resistance in batik cloth, so this study aims to determine the types of magnetic minerals in clay and their effect on color resistance in batik cloth. Clay samples were taken from two areas in West Sumatra, namely Pesisir Selatan and Sijunjung. Samples were characterized from the extraction of clay using X-Ray Diffraction, where measurements were taken before and after the dyeing process on the fabric. The results showed that the types of magnetic minerals found in the clay before and after dyeing the fabric were Maghemite. In addition, the non-magnetic mineral found in clay is Quartz. The color resistance test on the CL-SPPS-210314-2 fabric sample did not change color, on the contrary, the CL-PSBSJJ-210421 fabric sample experienced quite a change from the original color of the fabric or before washing.</span></p><p class="AbstractText"> </p>

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.

Estimation of Size, Volume and Weight of Oranges Using Digital Images Processing

Lima Puluh Kota Regency is one of the largest orange producing areas in West Sumatra. The common method for calculating the volume of fruit can be done manually with the water displacement method using a measuring cup filled with water then the fruit is put into, so the amount of spilled water is called an overflow which is equal to the volume of the fruit. This identification method will cause the quality of the fruit to be damaged due to immersion in the water (3). To overcome the shortcomings of this method, it is necessary to have a technology like digital image processing that is able to determine the volume and mass of fruit objectively without damaging the quality of the fruit. Digital image processing is an optical data recording system in the form of photos, analog in the form of video signals such as images on a television monitor which are directly stored on a magnetic tape. The purpose of this research is to estimate the weight and volume of orange using digital image processing technology. In this study, the oranges used were 3 levels of quality standard. The results obtained in this research are manual weight validation and weights using digital images with the coefficient of determination R2 = 0.9705, manual volume validation and volume using digital images obtained R2 = 0.9792. This shows that the program designed can estimate the volume and weight of oranges accurately.

Mapping the Diversity of Regional Characteristics Towards Sustainable Economic Strategic Area Development: A Case Study of West-East Corridor of West Sumatra Province

There are different characteristics distinguishing a region from the others, thereby, leading to the diversities in the regional potentials and problems as well as the strategic regional development policies to be implemented. The East-West Corridor is one of the eleven provincial strategic economic areas in West Sumatra. It covers nine regencies or cities and 65 sub-districts with different characteristics and typologies and this leads to diversity in the strategies to develop this area. This study aims to determine the diversity associated with the characteristics and typologies of the strategic area of the East-West Corridor. This involved using Principal Component Analysis (PCA) analysis technique, spatial clustering analysis, and overlay analysis. Moreover, the regional characteristics and typologies were grouped based on 17 observational variables used in producing four main components including trade and tourism services, agriculture, livestock/fishery, and tourism. The results of spatial clustering analysis produced 3 clusters which are the urban, desa-kota, and rural areas while the overlay analysis produced ten regional characteristics and typologies used as the basis to make strategies and policies for each region’s development and to increase investment opportunities in the strategic area of West-East Corridor and the Province of West Sumatra in general.

ANALISIS PERBANDINGAN TEBAL PERKERASAN LENTUR METODE ANALISA KOMPONEN BINA MARGA DENGAN METODE DESAIN PERKERASAN JALAN MDPJ 2017 ( STUDI KASUS : JALAN KURAI MUDIAK LIKI SULIKI )

Road infrastructure development has an important role as a supporter of social and economic activities in the community. However, there are still areas in West Sumatra, one of which is on Road Kurai Mudiak Liki, 50 Regency. Road Kurai is a connecting road between villages in the 50 Regency District which is still in the form of land and has a narrow width. In an effort to improve the condition of the Kurai road, it is necessary to plan for the highway by taking into account the vehicle load, weather, pavement material and soil carrying capacity. The bearing capacity of the subgrade is determined by the value of the California Bearing Ratio which greatly determines the thickness of the pavement layer because it will become the flexible pavement foundation that will be planned. Meanwhile, vehicular traffic, vehicle dimensions and payload will cause a compressive force on the vehicle axle which is supported on the road pavement which is channeled to the subgrade which is also an important reference in determining the thickness of the pavement. This study aims to determine the planning of flexible pavement thickness using the SKBI component analysis method 2.3.26.1987 and the 2017 Road Pavement Design Method No. 02/M/BM/2017 on Road Kurai Mudiak Liki Suliki. To find out which method is stronger for traffic load. The higher the traffic load, the thickness of each layer is important. Based on the calculation results of the two methods, the results obtained in the Component Analysis Method, namely Laston = 11.25 cm, Upper Foundation Layer = 15cm, Lower Foundation Layer = 20cm, and Road Pavement Design Method 2017 obtained calculation results AC-WC = 4 cm, AC-BC4 =6cm, AC-BC or AC Base =7.5cm, CTB3=15cm, Class A Aggregate Foundation=15cm.Keywords: Component Analysis Method, Road Pavement Design Method 2017, Road Kurai Mudiak Liki Suliki

Spatial Analysis for the Identification of Priority Areas Dengue in West Sumatera Province, Indonesia

Dengue is transmitted by mosquitoes in the genus Aedes, particularly Aedes aegypti and Aedes albopictus. West Sumatra Province is a tropical area in Indonesia where the two main mosquito genera are endemic in almost all regions year-round. This study analysed distribution of dengue, and defined the priority dengue areas in West Sumatra in 2017 using spatial autocorrelation (Moran’s I) and Moran’s scatter plot. The result revealed the global Moran’s index of the case patterns to be a cluster or positive correlation (I > 0, p < 0.01), and Moran scatter plot indicated associations between districts and their neighbours. Dengue cases in each district were described as high-high (HH), high-low (HL, hotspot), low-high (LH, cold spot), or low-low (LL). Districts identified as HH should be prioritized, and dengue must be controlled in HL and LH districts. In LL districts, dengue programs should be maintained. The results of this study could help implement strategies to prevent and control dengue.

Based on BAPETEN PERKA No. 9 of 2009 and UNSCEAR 2000, the radionuclide activity concentration was found still within safe limits. It does not pose a health hazard to the people living in the area.

Exploration and Identification of Arbuscular Mycorrhizal Fungi (AMF) in the Rhizosphere of Cocoa (Theobroma cacao. L) 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
