Abstract

Sembulang is located in a strategic maritime location and supports the majority of the local population to work as fishermen. In addition, Sembulang is also directly adjacent to the waters of Mubut Island which is one of the favorite tourist attractions in Batam and also to the waters leading to Bintan and Tanjungpinang, making it a popular port for people in that location. However, until now there has not been an official sea map or cruise line map for traditional fishing boats / local transportation to support economic and tourism activities there. The flow of a cruise is very closely related to the depth of a waters. Water depth data can be used by fishermen and boat captains as a reference when they are sailing across Sembulang Beach. The purpose of this study was to analyze the bathymetry conditions in Sembulang Beach, Galang, which were used as a reference for safe and efficient ship grooves considerations. Bathymetry mapping is done by using multibeam echosounder to create a seafloor topographic map at the research location which is then analyzed based on the depth and width of the cruise line which is ideal for the specifications of traditional fishing vessels. Based on the analysis that has been done, it can be concluded that only ships with size <5 GT with the form of "V" Pump Boat, "V", "V" High Bow, "V" Katir, "V" Without Katir, "U" Katir and 5 GTs with safe "U" and "V" shapes to be anchored at Sembulang pier. In other words, traditional fishing boats with a size of GT 10 GT are not recommended to dock at the pier.

Abstract

The rapid development of large-scale infrastructure in Indonesia indicates the need for solutions for fast crack applications with accurate results using methods that are efficient in terms of time and data generated. One example of the development of mapping technology in this modern era is aerial photography not only using manned aircraft, but you can also use an unmanned aerial vehicle or UAV (Unmanned Aerial Vehicle). This unmanned aircraft is better known as a drone, which is currently at an affordable price, easy to get and has the ability to shoot like a manned aircraft. Measurements were made using photogrammetric techniques from aerial photographs produced by drones. With results that have high accuracy, and can be done in the shortest possible time, then the use of drones in making topographic maps will be more widely used in the future. In our study and research survey that we conducted in the form of PBL (Project Based Learning) Politeknik Negeri Batam students in community service in the soaking village, Tanjung Riau, Batam Island, namely for making aerial photo maps using the DJI Phantom 4 RTK drone which we carried out in the village soak.

Abstract

The Covid-19 pandemic has caused all countries to implement strategies to suppress its spread, one of which is Indonesia, especially DKI Jakarta, which has implemented Large-Scale Social Restrictions (PSBB) since April 10 2020. Apart from being able to suppress the spread of the Covid-19 virus, PSBB is thought to have an impact on the environment, especially air quality in DKI Jakarta. According to research from the BMKG, Jakarta's air quality has improved over the last 5 years with the implementation of the PSBB. Besides analyzing the effect of the PSBB on air quality in DKI Jakarta, this research also aims to help governments in every region of Indonesia that do not have air quality monitoring stations. The method used in this study is to utilize Imagery from Sentinel-5P to measure concentrations of NO2, CO and SO2 gases validated using field data and utilize the NOAA Satellite acquired with Ventusky to analyze the effect of wind on the distribution of air pollution due to the PSBB. The results showed that the ratio of the average concentrations of NO2, CO and SO2 gases in DKI Jakarta decreased respectively to 27.70% ; 10.20% ; 42.06%. This shows an increase in air quality in DKI Jakarta due to the implementation of the PSBB. Comparison of the average concentrations of NO2, CO and SO2 gases in DKI Jakarta during the PSBB and after the PSBB increased slightly respectively to 11.92% ; 1.89% ; 35.84%. This shows that there is a decrease in air quality in DKI Jakarta which was caused after the implementation of the PSBB. Wind also affects the concentration of NO2, CO and SO2 gases. This is evidenced by the results of the correlation where the gas concentration is low when the wind speed is high, and vice versa. It was concluded that during the COVID-19 pandemic the concentrations of NO2, CO and SO2 in DKI Jakarta decreased and slightly increased after the PSBB, and wind could affect the distribution of these gases.
