Abstract

Education is one of the necessities of life that every individual must have. One level of education is a college education. In tertiary institutions' learning process, students are inseparable from financial needs for learning needs and living standards. This need forces students to do part-time jobs. Part-time jobs are growing from time to time. Part-time work has both positive and negative effects on student development in the world of work. This study aims to analyze part-time jobs for students of the 2017 Geography Education Department, their relation to learning activities, and the factors that motivate students to work part-time. This study uses a quantitative approach with simple analytical techniques. The population in this study were all students of the 2017 class of the Geography Education Department, with a sample of 20 students. Data collection techniques using a questionnaire. The study results show a significant effect of part-time work and learning activities with a substantial value of 0.037 <0.05. The main factor for students is working part-time because of the financial need for college needs and the standard of living. Part-time jobs done by students are online motorcycle taxi drivers, shopkeepers, salespeople, private tutors, and web programmers.Keywords: Part-Time, Student, Geography Education, Learning Activities

Abstract

The local active fault in Bali has a small magnitude (M<5) but has destructive potential because it is very close to residential areas. Mapping the fault area on Bali is needed to identify the parameters of faults. This study used gravity data from GGMplus, topographic data from DEMNAS, and lineaments using ALOS-2 PALSAR-2 data. Validation and interpretation using the geological map of Bali and seismicity data. We interpret the subsurface using the gravity derivative method to identify the type of fault movement. Identify fault locations using lineament extraction from SAR data processed by directional filters. The composite image red-green-blue (RGB) for HH, HV, and VV polarization was used for automatic lineament extraction and then corrected manually. The results of the gravity method succeeded in identifying 29 of the 30 faults from the geological map of the Bali sheet and a new spot from PALSAR-2. Bali land has 12 thrust faults, 11 strike-slip faults and six normal faults. The image of PALSAR-2 (L band) has succeeded in making a fault lineament map for the Bali region. The lineament extraction results from PALSAR-2 obtained four new faults (Pesanggaran, Sepang, Tegal Badeng, and Banyuwedang), while four faults were not identified (Tampaksiring Fault, Plaga, Mambal, and Munduk-Rajasa). NE-SW dominates the strike directions, and the dip angles are 45-80 degrees. We propose 30 faults in Bali, including 26 defects from geological maps with changes in length and location shift and four new marks extracted from automatic lineament.Keywords: Remote Sensing, Earthquake, Derivative Gravity, Lineament, SAR

Abstract

Land cover information is an essential aspect in the planning and management of earth modeling and understanding. Land cover changes impact the physical and social environment, such as hydrological conditions and ecological systems. This study aimed to identify spatial differences in the land cover of the Batur catchment area from 2015-2021 by using a remote sensing approach to describe the existing land-cover site and to detect its changes. The methods used in this study are a combination of the vegetation index and a supervised classification maximum likelihood algorithm with Landsat 8 OLI/TIRS in 2015 and 2021. Furthermore, the Change Detection Feature, identified from two image periods in 2015-2021 and processed, is used to detect changes in land cover. The accuracy assessment utilized QuickBird imagery recorded in 2015; field survey data were taken in 2021. The results showed that between 2015 to 2021, built-up area, bare land, shrubs, and lake have increased by 102,66% (306,01 ha), 27,95% (452,25 ha), 15,20% (215,72 ha) and 4,05 % (62,73 ha) while dryland forest and dry-dry-field have decreased by -25,84% (-606,29 ha) and -14.59% (-430,42 ha), respectively. The overall accuracy of the multispectral classification results in 2015 and 2021 was 82,63% and 89,57%.Keywords: Land-Cover Change; Batur; Catchment Area; Remote Sensing

Abstract

Geography planning is an essential element in the creation of a plan. Planners develop a method by analyzing data and identifying goals for the community or the development project. This study aims to analyze how planners or governments analyze geography planning and village funds to improve development programs. This research type is quantitative—data collection techniques using a closed questionnaire with a Likert scale model and interviews. The population and sample of the study were 47 people. The analysis technique was carried out by processing data collected from respondents, grouping data based on the type of respondent, making tabulations, and carrying out statistical test calculations. The results of this study found that the Village is a geographical manifestation caused by socio-economic, political, and cultural physiographical elements. Geographical planning analysis and village funds are intended for villages with each village planning village development needs. Support for geographic planning analysis and village funds can be seen from the achievement of policy aspects such as agenda setting, policy formulation, policy adoption, policy implementation, and policy evaluation in villages with a low relationship with effectiveness. From development programs. Public services to the point of development programs have an intense relationship, and the accountability dimension is classified as moderate. Productivity dimensions, service quality responsiveness, and responsibility for the development program's effectiveness. The policy on the simultaneous use of village funds and public services on the effectiveness of development programs has a strong relationship of 72.25. However, this study did not examine a low correlation of 0.27.36%.Keywords: Village, Policy, Public, Geography, Planning

Abstract

The strategy to improve the quality of education in schools is to improve the management of literacy culture. Literacy refers to the process of reading, writing, and speaking to build, integrate, and critique meaning. Many researchers studied teachers' role in improving elementary school students' literacy and forgot how lecturers also have an essential role. This study aims to identify geography education lecturers' role in measuring students' basic literacy and numeracy skills at SDN Pujut District, Central Lombok Regency. Research Methods use descriptive qualitative. Interviews, observation, and descriptive analysis of documents by purposive sampling obtained data. To increase the credibility of research informants using the principle of data saturation. The results of this study show that students' literacy and numeracy skills are still low because teachers' ability in Central Lombok Regency is also considered to have decreased, so the support of parents is considered a servant. This research also shows that the role of geography education lecturers is very significant in measuring literacy and numeracy skills applied to all fields of learning in an integrated manner so that the roles of teachers and lecturers both have an essential role in measuring the literacy and numeracy of elementary school students.Keywords: Lecturer Role, Literacy Ability, Basic Numeracy of Students

Abstract

Bandung is West Java's largest metropolitan city and Indonesia's third largest. The city of Bandung is very strategic in various aspects, such as accessibility, communication, public facilities, and the economy. The Increased population in Bandung indicates more complex ongoing human activities, which can then affect changes in land use. The land covers in urban areas tends to change more drastically over a short period e than in rural areas because of rapid urbanization. Therefore, urban phenomenon changes are ideally monitored and detected from satellite images with a multitemporal resolution. Vegetation greenness and built-up areas can identify through multitemporal remote sensing imagery. Changes in vegetation and built-up area can monitor using remote sensing with multitemporal imagery. The analysis of changes in vegetation and built-up area studied in Bandung City represents an area with rapid population growth. This study aims to: 1) Identify changes in vegetation greenness in Bandung City between 2014 and 2021, 2) Identify built-up area changes in Bandung City between 2014 and 2021, 3) Analyze the relevance between vegetation greenness and the built-up area in Bandung City—the correlation between NDBI and NDVI through selected samples is representative of all data in Landsat 8 imagery. The proportion between the values of NDBI and NDVI samples is 0.9034. So, it is concluded that the two variables are positively correlated. Therefore, the study’s results recommend preserving vegetated land cover to conserve natural resources and prevent increased land surface temperature.Keywords: Remote Sensing Imagery, Built-Up Area, Vegetation Greenness, Bandung City

Abstract

In political preferences, religion plays a vital role as a consideration for the millennial generation. This is because Indonesia still considers religion in setting policies as it does in political parties and general elections. This study analyzes the political communication system of millennial Muslim Islam on social media in the face of the 2024 presidential election (netnographic analysis). This study applies the netnographic research method through a qualitative approach to understand how the Islamic political communication system works in millennial Muslim society on social media and the geopolitics of millennial Muslims in Indonesia in the face of the 2024 presidential election. Data collection uses analytics related to election data—President in 2024. The study results show that the application of political communication among millennial Muslims on social media is in the form of support and criticism on the hashtag #pemilu2024. Social media proves that distance and time limits are not obstacles to voicing opinions, criticizing and supporting each other. Several things that can be done to map Islamic political communication systems and millennial Muslim geopolitics on social media include: (1) Analyze Islamic political trends that occur on social media, such as Twitter, Facebook, and Instagram, by searching for keywords related to Islamic politics and monitor how communication patterns are between Muslim millennials; (2) Understanding millennial Muslim sentiments on social media by reading and monitoring conversations on social media; and (3) understand the patterns used in communicating, taking into account the type of content they share, the frequency of social media use, as well as the most used platforms. Too much social media reach without knowing boundaries makes social media challenging to control. The strength of political competition becoming increasingly evident must be accompanied by carefulness in filtering information not to complicate the situation. As millennials amid vulnerable hostilities, they should be able to become pioneers or fortresses in avoiding the opposing currents of the impact of social media in political times.Keywords: Political Communication, Millennial Muslims, Geopolitical Mapping, Social Media, Presidential Election

Abstract

The coral reef ecosystem has a significant physical and biological function and is also one of the coastal ecosystem components apart from the seagrass and mangrove ecosystem. Besides their ecological function, the coral reef also has an economic function. The condition of the coral reef ecosystem in Malalayang Beach has been changing for years. The utilization of remote sensing images can monitor current conditions. This research aims to map the coral reef ecosystem mapping in Malalayang Beach, Manado and conduct a test for the accuracy of coral reef ecosystem mapping using field survey data as a classification and validation sample. PlanetScope multispectral image has four channels to detect underwater objects: red, green, blue and near infrared. PlanetScope level 3B image for the research has a surface reflectance value for its pixel. The image processing stages of this research consist of sunglint correction, water column correction, and then continue to classify the coral reef ecosystem using random forests algorithm. Classification and accuracy training sample data were obtained using the photo transect technique. The sunglint correction regression equation is between 0.27 – 0.38. The coefficient of attenuation ratio in B1 is 0.927797938, B2 is 0.168841585, and B3 is 0.29033029. This value then becomes the input for the Lyzenga formula. The classification accuracy for level one using random forests is 72,54%, and the accuracy for level two mapping is 37,61%.Keywords: Coral Reef Ecosystem, Planetscope, Random Forests

Abstract

Local knowledge is knowledge owned by a community in the form of information that is people's knowledge. As a country with diverse cultures, Indonesia has a variety of local knowledge which has become an icon of the community, used in maintaining natural conditions and survival. One of the community's local knowledge areas is the process of fishing in the Gayo community. The Gayo ethnic group is a native of Central Aceh District, located in the Gayo highlands. Local knowledge possessed by the community is inseparable from global influences that continue to grow. Global forces will shape culture, modify value systems, and affect social identity. This research was conducted in Mendale Village, Kebayakan District, Central Aceh District. This study aims to analyze local and global knowledge and find out the acculturation of people in fishing. The research method used is a qualitative method with a new ethnographic approach. Data collection techniques are interviews, observation, and documentation studies. The results of interviews and observations were analyzed thematically and grouped under the same theme. Each theme is discussed in detail and then interpreted to obtain data that can provide answers to research problems. The research results show that local knowledge of fishing is a culture passed down from generation to generation. Local fishing knowledge cannot be applied in all catches, only used in fishing in the lake. Existing local knowledge is mixed with global knowledge so that local knowledge of fishing is not the same as the culture left by fishermen in the past.Keywords: Local Knowledge, Gayo, Community Fishing, Acculturation
