Abstract

One part of the hydrologic cycle which has a major influence in increasing the amount of river flow discharge is surface runoff. The higher surface runoff discharge, causing the possibility of surface flooding, therefore required an empirical model that can calculate the amount of surface runoff so as to produce updated data and quickly change according to their needs. One of the empirical methods that can be used to calculate the amount of surface runoff is by using the curve number method. This research is done by utilizing remote sensing image, that is, ALOS AVNIR-2. Data extraction from ALOS imagery includes land cover information using multispectral classification analysis, slope inclination information through visual interpretation, and land use interpretation. The runoff that occurred in Banjarnegara Regency tends to be high, that is, 61.24 percent of the total area of the research area. Large runoff with very high/extreme class spread on the form of hilly land to the old volcano complex at the study site. The runoff in the medium to low class only covers 3.56 percent of the total area and is distributed on the fluvial form with the flat-to-flat slopes. The result of analysis of runoff data is obtained from slope analysis and type of land use in the research location. Increasingly steep slope with little vegetation-land use, then the greater the runoff that occurs. Finally, the research result could be implemented into higher student class activity, especially in remote sensing classes, GIS, cloud computing, and big data analysis. By this process, the students will be improved their skills in analyzing imagery data as well as create new information derived from the remote sensing data.

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

Kegiatan Project Based Learning (PBL) di Program Studi Teknologi Geomatika, Politeknik Negeri Batam, dengan kompleksitas dan jumlah tim sumber daya manusia yang cukup banyak, memerlukan evaluasi manajemen K3 yang memadai. PBL ini melibatkan berbagai kegiatan proyek dan tahapan, seperti persiapan pra lapangan, akuisisi data lapangan, pengolahan data laboratorium, uji lapangan, serta pelaporan dan analisis kegiatan. Tujuan kajian ini adalah merefleksikan evaluasi risiko K3 dalam pelaksanaan PBL dari semester Ganjil 2020/2021 hingga semester Ganjil 2023/2024. Metode yang digunakan adalah HIRARC (Hazard Identification Risk Assessment and Risk Control), mencakup identifikasi, asesmen, dan kontrol risiko. Data identifikasi dan asesmen risiko diperoleh dari data historis, pengamatan lapangan, dan observasi kerja. Kegiatan PBL diklasifikasikan ke dalam risiko rendah, sedang, dan tinggi. Peningkatan risiko bahaya umumnya disebabkan oleh kurangnya induksi K3, penggunaan metode dan alat yang tidak tepat, kurangnya tanda keamanan, PPE yang tidak sesuai standar, dan minimnya supervisi oleh manajer proyek. Pengendalian risiko dilakukan melalui dokumen standar dan penggunaan PPE yang sesuai dengan kegiatan yang dilakukan, termasuk dalam rencana pelaksanaan proyek (RPP).Kata kunci: Hazard Identification Risk Assessment and Risk Control, Project Based Learning, Manajeman K3.
