Most of economic regional developments in Indonesia depend on freight transport system, efficient freight transport system would produce low cost of transport, it will affect on the price of good and the market. Freight transport in Indonesia is usually served by trucks, these mode has been identified as the transport mode that operate with high cost and inefficient. This paper shows the result of research on freight transport in West Sumatra that operated in Padang. This result is based from direct interview on 100 truck drivers in Padang. It shows that majority the trucks serve freight transportation between cities in West Sumatera and other Province in Sumatera island, most of goods that transported from Padang are construction materials. During deliver the goods, they require time about 1-2 days and always stop several times for break and eat. This is because the drivers drive the truck alone. The total operational cost spends during delivery to other province in Sumatera Island between Rp 1 millions - Rp 2 millions, there are illegal retributions for about 1-5% of operational cost, these retributions are conducted by person or organization. The Regulations that impede the performance of freight transport are prohibition of trucks enter the city in the morning and afternoon at peak hours.

Background and Study Aims. Good motor coordination is needed to achieve good fundamental motor skills. This study aimed to analyze and describe the relationship between fundamental motor skills and motor coordination performance of elementary school students aged 7 to 9 years old. Material and Methods. The subjects were elementary school students in grades 1, 2, and 3 with a total number of students was 478 (248 male students, and 230 female students) in 8 cities and regencies in West Sumatera, Indonesia. This study used a cross-sectional research design. The fundamental motor skills were examined using the Test of Gross Motor Development-Second Edition. This included assessing locomotor skills (running, galloping, sliding, leaping, hopping, and jumping) and object control skills (striking, catching, throwing, dribbling, rolling, and kicking). Motor coordination performance was assessed by using the Körperkoordinations Test für Kinder including balance beam, moving sideways, jumping sideways, and eye-hand coordination. The data were analyzed by using IBM SPSS statistic version 25. Results. Students in urban areas demonstrated certain levels in Gross Motor Quotients scores, while their counterparts in rural areas achieved marginally higher scores with slightly less variation. In schools where Physical Education teachers were present, students generally scored higher compared to schools without Physical Education teachers, albeit with a bit less variation in the latter. When comparing motor coordination performance, students in urban areas typically outperformed those in rural areas, exhibiting slightly more consistent scores. Similarly, students with access to Physical Education teachers showed better motor coordination performance than those without, though with a somewhat greater range in their scores. A noticeable trend was observed in the Gross Motor Quotients scores of Fundamental Motor Skills, which tended to decrease as age increased. Conversely, students' motor coordination performance generally improved with age. Supporting these observations, the result of the one-sample Kolmogorov-Smirnov test, obtained from Asymp. Sig. (2-tailed), was 0.200 > 0.05. Additionally, the Pearson correlation value between motor coordination performance and fundamental motor skills was 0.633 with a sig value of 0.000, indicating a significant relationship. Conclusions. Based on the study's findings, it is recommended to focus on enhancing motor skill programs for children in rural areas. Schools should invest in Physical Education teachers, especially where they are currently absent, to benefit children. Age-specific programs are needed to address the decline in Gross Motor Quotients with age in children. Regular monitoring and evaluation of these initiatives for children are essential.

Solar energy is among the sustainable and renewable energy sources that has become an important and inevitable part of our lives today. It is of great importance to consider economic, environmental, and social factors in determining the installation locations of solar power plants (SPP). In this study, we aimed to determine suitable areas where SPP can be established in Safranbolu District by using the fuzzy analytical hierarchy process (FAHP), which is one of the multiple criteria decision making (MCDM) method together with Geographic Information Systems (GIS), to enable the decision-makers to express their preferences in approximate or adaptable ways. The criteria addressed in the technical analysis process were also determined by supporting the basic principles of impact assessment systems. Within the scope of the environmental analysis, the relevant national and international legal frameworks were also examined and the legal constraints were identified. Thus, in the process of determining the optimal areas for SPP, it has been attempted to produce sustainable solutions that are expected to have minimal impact on the integrity of the natural system. This study was carried on within a scientific, technical, and legal framework. According to the results obtained, the Safranbolu District had low, medium, and high sensitivity properties for SPP construction, and the areas suitable for SPP construction provided medium and high sensitivity of 10.86% and 27.26% correspondence detected according to the Chang (Eur J Oper Res 95(3): 649-655, 1996) and Buckley (Fuzzy Set Syst 17(3): 233-247, 1985) methods, respectively. There are very suitable areas for SPP installations in the central and western parts of Safranbolu District, and there are also areas suitable for SPP installation in the northern and southern parts of the district. Thanks to this study, suitable SPP establishment areas were determined for the under protection in a location in Safranbolu where clean energy is needed. It was also observed that these areas do not conflict with the basic principles of impact assessment systems.

Recently, due to extensive use of fossil fuels, the problem of global warming has been raised. For solving this problem new energy sources have been growing extensively. In this paper the selection of the optimal energy supply system is considered. Due to energy policies in recent years this selection is not only based on financial aspects but also environmental and social aspects, this problem considers as a multi criteria problem. In this paper, several alternatives including renewable energy sources, micro CHP systems and conventional system has been compared by means of an integrated model of linear programming and multi criteria approach with respect to the end user requirement. New factors like availability of sources, fuels' price volatility, besides traditional factors are considered beside financial, environmental and social parameters. For each parameter a mathematical index is obtained for systems using a mathematical programming model and based on these indexes using a multi criteria decision making method different systems are evaluated. Three multi criteria decision making methods tools are discussed in this paper. The results from each approach have been compared in order to see the sensitivity of the results to each aspect of evaluation, several scenarios have been defined and the results have been compared. The results show that renewable sources and micro CHP systems are good alternatives for conventional systems when a strong attention is paid to environmental issues, without considering environmental issues renewable energy sources cannot compete with conventional systems.

Padang City, as one of populous city in West sumatera province, well known as their wandering culture. This wandering culture causes the number of people using public transport to go out increased, especially the Inter-City Inter-Provincial bus (AKAP) users. Unfortunately, high public interest in using AKAP buses has not been supported by the adequate system of AKAP bus companies. Current system affect prospective passengers into problems while searching for the location of a transport company. It caused by limited source of information media, such as banners or word-of-mouth information. This lack of information reducing the user's comfort in using AKAP bus. This Information system of rental and booking bus and travel tickets in Padang City was created using the PHP programming language using the CodeIgniter framework and MYSQL for the database. The design of this information system is done to produce a web-based information system that provides information of transportation companies location to facilitate passengers and prospective passengers to come, and facilitate the process of booking tickets. The design of this information system displays the location information, prices, facilities, and transportation fleet that available in each company.

Regional Suitability Mapping (PRSM) was initiated in 2013 with the aim of optimizing operational cost efficiency, minimizing potential incidents during jack-up emplacement and assist in planning for rig selection. This paper will highlight the performance of jack up rig leg penetration prediction using PRSM for Offshore Malaysia. PRSM comprises data analysis and integration from various sources such as geotechnical and geophysical site investigation data and data from rig entries. These data sets are then uploaded to a web-based Geographic Information System (GIS). The jack up rig leg penetration range predicted from PRSM GIS database is then compared to the actual jack up rig leg penetration. A comparison to the calculated jack up rig leg penetration was also made and the differences between these results are postulated. A total of 23 recent jack up entry sites has been chosen randomly, which comprises 8 locations in Offshore Peninsular Malaysia, 12 locations in Offshore Sarawak and 3 locations in Offshore Sabah. The expected leg penetration at these locations were acquired from PRSM GIS. Results show that 75.0% of the sites in Offshore Peninsular correlate with the prediction range from PRSM GIS while only 27.3% of the sites in Offshore Sarawak correlate with the prediction range. For Offshore Sabah, all the locations correlate with the prediction range obtained from PRSM GIS. Results from predicted spudcan penetration calculated based on ISO 19905-1 (2016) against the actual penetration results show that 87.5% of the sites in Offshore Peninsular falls in between the ±10% reference band while 63.6% of the sites in Offshore Sarawak falls in between the ±10% reference band. However, none of the sites in Offshore Sabah falls in between the ±10% reference band. Findings from this exercise indicates area in Offshore Sarawak consist of two different features. Firstly, there are locations with thick sand layer close to seabed associated with shallow penetration of spudcans. Secondly, locations with presence of homogeneous clays with linearly increasing strength associated with deeper penetration of spudcans. Moreover, the available data around Offshore Sarawak field are scattered between one another, which leads to bigger data gaps. The shallow leg penetrations in Offshore Sabah are associated with the presence of coral and/or sand close to seabed. This paper aims to showcase the use of big data and GIS to help in jack up leg penetration predictions hence optimizing the operational cost efficiency, minimizing potential incidents during jack-up emplacement.

In the current context of renewable energy development, the most important task is to minimize the environmental impact of wind farms (WPPs) on the environment. The use of geographic information systems (GIS) allows for effective analysis and modeling of the impact of WPP placement, taking into account environmental, landscape, climatic and social factors.The article considers the use of geographic information systems (GIS) to assess the environmental impact of the location of a wind farm (WPP) on the territory of the "Polonyna Runa" tract of the Turye-Remetivka territorial community.The study involves the collection and processing of spatial data, including relief, wind speed and direction, the presence of protected areas and habitats of sensitive flora and fauna. GIS will be used to analyze visual and noise impacts, assess risks to biodiversity and public health, and model alternative siting options.The assessment results contribute to making informed decisions regarding the choice of a location for wind power plants, reducing negative environmental impact and ensuring a balance between the development of green energy and the preservation of the natural environment.

Global warming is among the important environmental problems of the earth. The present research aims to study temperature variations around the world. For this purpose, the monthly temperature data of 178 points from the NOAA site were studied from 1950 to 2019. In this study, the temperature changes were investigated in terms of its increase, decrease, and significance level by the Mann-Kendall method. Geographic Information System (GIS) and interpolation methods were used to determine the changes in temperature in global warming maps. According to the obtained results, except for 3.8% of the designated area, other parts of the world show change toward warmer conditions. Overall, the world's land temperature has increased by 1.08℃ during the study period. Also, about 85% of the designated area shows moderate and severe hazardous conditions in terms of global warming. The spatial analysis showed higher change and hazardous conditions for global warming in mid-longitude and high-latitude close to both poles.

Both hydropower dams and global warming pose threats to freshwater fish diversity. While the extent of global warming may be reduced by a shift towards energy generation by large dams in order to reduce fossil-fuel use, such dams profoundly modify riverine habitats. Furthermore, the threats posed by dams and global warming will interact: for example, dams constrain range adjustments by fishes that might compensate for warming temperatures. Evaluation of their combined or synergistic effects is thus essential for adequate assessment of the consequences of planned water-resource developments. We made projections of the responses of 363 fish species within the Indo-Burma global biodiversity hotspot to the separate and joint impacts of dams and global warming. The hotspot encompasses the Lower Mekong Basin, which is the world’s largest freshwater capture fishery. Projections for 81 dam-building scenarios revealed progressive impacts upon projected species richness, habitable area, and the proportion of threatened species as generating capacity increased. Projections from 126 global-warming scenarios included a rise in species richness, a reduction in habitable area, and an increase in the proportion of threatened species; however, there was substantial variation in the extent of these changes among warming projections. Projections from scenarios that combined the effects of dams and global warming were derived either by simply adding the two threats, or by combining them in a synergistic manner that took account of the likelihood that habitat shifts under global warming would be constrained by river fragmentation. Impacts on fish diversity under the synergistic projections were 10–20% higher than those attributable to additive scenarios, and were exacerbated as generating capacity increased—particularly if CO2 emissions remained high. The impacts of dams, especially those on river mainstreams, are likely to be greater, more predictable and more immediately pressing for fishes than the consequences of global warming. Limits upon dam construction should therefore be a priority action for conserving fish biodiversity in the Indo-Burma hotspot. This would minimize synergistic impacts attributable to dams plus global warming, and help ensure the continued provision of ecosystem services represented by the Lower Mekong fishery.
