The Trosobo-Kletek Highway is one of the roads that has a high level of vehicle density so that it appears that it has experienced traffic jams several times. This is also coupled with the presence of side barriers such as vehicles in and out. So that the Trosobo-Kletek Highway section often experiences traffic jams that occur not only at certain hours, because on this road section there are many factory areas. The important role of this road resulted in a decrease in the level of service. Based on this, it is necessary to monitor the quality of a road segment based on the level of service. In this study, the PKJI 2014 was used to calculate the road performance. As for some of the data needed such as traffic volume, road geometry, and vehicle speed.

Shoreline is a line where the edge of the land and the sea met. Various amount of shore construction was built around the shoreline. The safety of surrounding community near the shoreline should be considered before the government planning on near shore and shoreline facility. Therefore, breaking waves height become important because of the impact that it brought to the shoreline, such as the destructive energy that breaking waves generates which would wipe anything that existed alongshore. Using the data collected from BMKG (Meteorology, Climatology, and Geophysics Council), maximum wind stress at the Panceng Sub-District was 17,2 m/s. Average effective fetch at Panceng Sub-District was 331,68 km with 5 m significant wave height and 11,2 s period. Breaking wave height at Panceng Sub-District is 5,5 m.

West Papua Province is a new province with a relatively low economic level due to inadequate road access. Many areas are isolated, which hampers the distribution of goods and services. One isolated area is the Kaimana Regency with Fakfak Regency. Therefore, to open regional isolation and improve the local community's economy, it is necessary to plan a road in the Inari – Bofuwer segment as an infrastructure that can connect the two areas.Road planning consists of geometric road planning based on Tata Cara Perencanaan Geometrik Jalan Antar Kota No. 38 Tahun 1997, road pavement thickness planning using the 2017 Bina Marga method, and road drainage planning based on Perencanaan Sistem Drainase Jalan Tahun 2006.The geometric design of the road for horizontal alignment obtained 13 Spiral-Circle-Spiral bends and 5 Spiral-Spiral bends. In contrast, the vertical alignment consists of 13 concave curves and 13 convex curves. The road pavement uses Burda or Burtu with a thickness of LPA Class A 250 mm, LPA Class B 110 mm, and a soil stabilization layer 150 mm. The planned road drainage channel is in the form of a trapezoid with a width of 0,4 – 0,6 meters and a height of 0,85 – 1,15 meters.
西巴布亚省是一个新省，由于道路不足，经济水平相对较低。许多地区是孤立的，这阻碍了货物和服务的分配。一个孤立的地区是凯马纳摄政和法克法克摄政。因此，为了打破区域隔离，改善当地社区的经济，有必要在伊纳里-鲍弗尔段规划一条道路，作为连接两个地区的基础设施。道路规划包括基于1997年塔塔卡拉perencananan Geometrik Jalan Antar Kota No. 38 Tahun的几何道路规划，使用2017年Bina Marga方法的道路路面厚度规划，以及基于perencananan system Drainase Jalan Tahun 2006的道路排水规划。水平走向道路的几何设计得到13个螺旋-圆-螺旋弯道和5个螺旋-螺旋弯道。相比之下，垂直对齐由13条凹曲线和13条凸曲线组成。路面采用Burda或Burtu, LPA a级厚度为250毫米，LPA B级厚度为110毫米，土壤稳定层为150毫米。规划的道路排水通道呈梯形，宽度为0,4 - 0,6米，高度为0,85 - 1,15米。

The waters of Teluk Lamong are located on the north sea coast of Surabaya, which is directly adjacent to the Gresik Regency. Lamong Bay is famous as a strategic port place on an International scale. Along the coastal waters of Teluk Lamong, some rivers flow in Lamong Bay. These activities can lead to interaction between fresh water and seawater. This interaction affects the pattern of salinity spread and sea surface temperature in the waters of Teluk Lamong. Salinity and Sea Surface Temperature is one of the biggest factors causing corrosion in the sea that will damage the structure of buildings around the sea. It is expected that in this research as information about the waters of Teluk Lamong for data information or database utilization in the field of civil engineering, among others, port maintenance and coastal building planning. Based on this background, research is needed to monitor the spread of salinity values and sea surface temperatures in Lamong Bay using Landsat 8 satellite imagery for the years 2016 and 2020. The result of modeling the algorithm obtained, the model of the algorithm used to process the salinity of the image is the wavelength Band_4 in the Equation Power with the model algorithm y = 25.437x-0.046, and the degree of determination value R² = 0.5825. While sea surface temperature in power equation with algorithm model y = 302.14x0.0029 and determination value R² = 0.4182. The results of an analysis of the T-test and validation test can be qualified. The results of the analysis of imagery data showed salinity distribution ranged from 27.33 (ppm) to 29.9 (ppm), while sea surface temperatures ranged from 303.95 Kelvin to 304.39 Kelvin.

Pavement roads in Indonesia often suffer premature damage. Efforts to overcome road damage need to be done by using pavement materials suitable for the climate in Indonesia. This research discusses the comparison of Pertamina asphalt 60/70 and Shell asphalt 60/70 in the concrete asphalt mixture. The variation of the bitumen content used in this study was 4%, 4.5%, 5%, 5.5%. From the test results, it can be concluded that Shell asphalt 60/70 penetration is relatively better in terms of the considerable penetration value, softening point, stability value, flow, and Marshall Quotient, which are higher than Pertamina's 60/70 penetration asphalt.

In investing, there is definitely a risk, as well as the concession of toll roads. Risk analysis is used to anticipate losses due to an element of risk at each investment stage. The results of the analysis show that the highest risk probability for the Solo-Ngawi toll road is land availability and the influence of weather during development and the highest risk impacts are land availability, the potential for revolution in state governance. Based on the results of the analysis, the investment risk level of the Ngawi Solo Toll Road is included in the moderate risk category, so there is a need for cooperation in risk assurance by the Insurance Agency so that the risk level can be reduced to be lower than before.

Indonesia is a country that has a high population density. The increasing population causes an increase in the demand for household needs. As time goes by, human needs are increasing day by day. Starting from primary needs to secondary needs. The city of Surabaya is the second largest metropolitan city after Jakarta with a population of around 2,874,314 people in 2020. With such a large number, of course, it has various kinds of demands to fulfill primary needs, Alfamart and Indomaret as the two largest retail companies in Indonesia are trying to be in the midst of Public. However, the uneven distribution of Alfamart and Indomaret locations causes the public to be often confused about their existence. To meet the need for information dissemination in that location, the system will be made based on mobile web so that the system can be accessed via a mobile smartphone device that is equipped with a GPS (Global Positioning System) so that it can find out the coordinates of the location of Alfamart and Indomaret, namely in the form of latitude and longitude data. This will make it easier for people who want to know the location and know the distance to the intended location and data by utilizing services from Open Camera and Google Maps.

Goods movement using container are quite efficiently assessed because it can carry a great amount of goods fit to container capacity. Freight transportations is a primary component of all supply-chain and logistics systems, but in contrary using a truck as its transportation means causing many problems such as air and noise pollutions, traffic congestions, road accidents and road damage. Depart from this facts, so government is looking for another means of freight transporter which more efficient with a bigger load capacity advantages. This options goes to train as a solutions of intermodal freight transportations lack. In order to supporting intermodal freight transportations, right now double track of railway is available for Jakarta – Surabaya route (Northern line route). By now, noted that freight transportation with double track railway frequency is potentially increase to 15 trip per days with capacity 500 TEU (Twenty feet Equivalent Units) per days and fuel consumptions (with truck) can be thrifted into 115 kl per days also reducing carbon monoxide emission amounts 350 tons per days. According with an official statements from Directorate General of Railways, Ministry of Transportations, explained that Jakarta – Bojonegoro route on double track railway is fully operated so this paper is conducted to determining feasibility of railway structure performance due to freight intermodal transportations at Bojonegoro – Kalitidu route. Railway structure performance feasibility is observed from loading distributions, rail strength, rail sleeper strength, and railway subgrade endurance to planned freight trains. As a result of this research obtained that tension force that occurred on rail is 830,10 kg/cm2 < permitted tension on rail (first class rail) 1325 kg/cm2. So, tension force that occurred on rail is safe. Moment force that occurred on rail bottom is 14521,25 kg.cm < permitted moment force (150.000 kg.cm) Moment force that occurred in the middle of rail sleeper is 58993,978 kg.cm < permitted moment force (93000 kg.cm). Tension force that occurred on above railway subgrade (σ2) is 4,17 kg/cm2 < qu (29,671 kg/cm2). It means that railway subgrade is capable to supporting load of freight transportation operations along Bojonegoro – Kalitidu route.
