Abstract

Regional inequality or disparity is a natural consequence of development and an unavoidable stage. This happens because of differences in population, natural resource potential and geographical conditions in each region. This research aims to analyze public service centers, inter-district interactions, and settlement patterns in the context of regional development in Samosir Regency. The study uses a descriptive method with a quantitative approach to analyze the centers of public services, inter-district interactions, and settlement patterns among districts in Samosir Regency using the tools of centrality index analysis, gravity model, and nearest neighbor analysis. The analysis results show that the public service facilities in Samosir Regency in 2021 include 517 units of educational facilities, 442 units of healthcare facilities, 561 units of religious facilities, and 2,418 units of economic facilities, with the service center located in Pangururan District with a total availability of 1,081 units, which has the highest centrality value of 966.63. The largest inter-district interactions occur in Palipi District with a total interaction of 11,671,532.31, while the smallest interaction occurs in Simanindo District with a total interaction of 749,250.15. The settlement pattern in Samosir Regency consists of 1 district with a random settlement pattern and 8 other districts with clustered settlement patterns. In the development of Samosir Regency, the influence of district interactions, service centers, and settlement patterns are important factors to be considered.Keywords: District, Service Center, Interaction, Settlement Pattern

Abstract

Community activities before, during, and after the Covid-19 pandemic have undergone significant changes. This is due to the limitation and exemption of activities set by the government which can also result in changes in surface temperature. Physical separation from the Large-Scale Social Restrictions (PSBB) has led to a decrease in communal activities like traffic and the industrial sector, which has a policy of allowing most employees to work from home. This study intends to examine variations in Bandar Lampung surface temperature that took place in 2020, 2021, and. Identifying surface temperature using remote sensing technology, including Landsat 8 and Landsat 9 images. Both of these images have advantages with a large number of bands, especially the presence of a Thermal Infrared Sensor (TIRS) wavelength which has a sensitivity to detect temperature. Utilization of this wavelength can distinguish parts of the earth's surface that have a hotter temperature than the surrounding area. The land surface temperature (LST) approach can be used to determine the dynamics of surface temperature variations before, during, and after the Covid-19 epidemic. Image processing and analysis are done using Google Earth Engine. The results of the analysis of surface temperatures before Covid, the image recording time in 2020 has a value range of 13oC - 32oC, during the occurrence of Covid, the 2021 recording time has a value range of 3oC - 33oC, while after Covid, the 2022 recording time has a value range of 18oC - 32oC.Keywords: Covid-19, Landsat 8, Landsat 9, LST

Abstract

The COVID-19 pandemic transformed the industry into the strongest online industry of the last decade. One of the commodities that have experienced faster sales since the COVID-19 pandemic is healthy food; fruit is one of them. As a response to the crisis, online fruit traders have emerged using social media. Unfortunately, not all community groups can adapt to technology. Fruit traders who stay in the kiosk (selling offline) are included in the new left-behind group due to their inability to technology adaptation. This study aims to differentiate the sales flow of fruit commodities (before and after the appearance of online sales) and describe the advantages and disadvantages of each group (online traders and kiosk/offline traders). The data to answer the two research goals were processed in a qualitative descriptive way. The results show that online traders have a shorter sales flow than kiosk traders. The main advantages of online traders include using social media, which makes it easier to find market and customer information, low prices, and ownership of transportation. Meanwhile, the main disadvantages of offline fruit traders are the limited quantity of human resources, the inability to operate smartphones and social media, and not always having transportationKeywords: New Competition, Fruit Sales Flow, Online Trader, Kiosk Merchant

Abstract

Changes in marine landforms in coastal areas are relatively rapid and need to be analyzed to determine environmental management policies. Complex marine landforms are found in the coastal areas of Pangandaran Regency and have strong pressure to fulfill community activities, not only for local communities but also for outside communities. Basically, community activities are adapted to regional environmental conditions. The aim is to optimize the potential of natural resources and minimize environmental degradation, but in reality, this has not been fully implemented. The method used in this research is a descriptive method using a field survey approach. Marine landforms resulting from the accretion process in the Pangandaran coastal area are spit landforms, aeolian-marine sedimentation in the form of coastal dunes, fluvio-marine sedimentation in the form of estuaries and alates, organic-marine landforms and white sand beaches associated with reefs. The landforms resulting from erosion are Cliffs, notches, wave-cut platforms, stacks, and stumps. The impact of landforms resulting from sedimentation in the Pangandaran coastal area is mainly spit landforms that cover river mouths and the occurrence of flooding, puddles, and even accumulation of organic waste, landforms resulting from erosion, the impact of which is the decline of the coastline accompanied by avalanches of material towards the sea, especially on beaches that have non-resistant rocks such as sedimentary rocks and alluvial deposits. Management of the Pangandaran coastal environmental area must be carried out in an integrated manner, land buritan (hinterland), which has steep slopes and resistant rock, is designated as limited production land, and the development of the spit at the river mouth is made into a jetty, and the beach has beach cups waves with rip currents and water bathymetry. -10 meters above sea level, a wave-protecting wall must be built, and the coastal border area must be used as vegetative-based conservation land.Keywords:  Marine landforms, Coastal Management, Pangandaran

Abstract

The internet provides tremendous educational benefits for students and also provides better communication, information, and social interaction opportunities for young people, but excessive internet use can lead to negative psychological addiction. This study aims to quantitatively describe the tendency of internet addiction in the population of students majoring in Public Administration from the class of 2020, 2021, and 2022. The total sample taken was 142 people, including all students from the three batches. The data analysis method applied in this research is the crosstab or cross tabulation analysis technique. The data analysis process involved the use of SPSS V.25 statistical software. From the results of the analysis of gender and range of addiction, it can be seen that the majority of respondents, both males (66.7%) and females (69.9%), experience a moderate level of internet addiction, especially social media. The number of respondents who experienced moderate addiction reached 98 out of a total of 142 respondents. In the analysis of respondents' age groups and range of addiction, it can be seen that three age groups dominate, namely 19, 20 and 21 years old. Of the 28 respondents aged 19, 17 of them experienced moderate addiction. In the 20-year-old age group, out of 43 respondents, 33 were classified as moderately addicted. While in the 21-year-old age group, out of 37 respondents, 26 of them also showed a moderate level of addiction. Furthermore, the tendency of internet addiction in college students is dominated by two main aspects: characteristics and excessive use. Students who feel attached to the internet tend to always think about and find it difficult to control their use. Keywords: Tendency; Addiction; Internet; College Students

Abstract

Sawo sub-district of North Nias Regency has a mangrove ecosystem that has been designated as a Regional Marine Conservation Area (KKLD) with an area of 29,230.85 ha. The 2005 earthquake and tsunami are reported to have caused damage to mangrove ecosystems due to rising land levels. The increase in land surface has resulted in the destruction of mangroves in this area. This impacts the sustainability of the mangrove ecosystem in this region and is important to study. This study aims to analyze changes in mangrove land cover after the tsunami in 2006 to 2022 and to analyze the impact of changes in mangrove land cover. The results found that mangrove land cover continues to experience a reduction in area; in 2006, an area of 139.78 ha continued to decline until the remaining 70.87 ha in 2022. This is due to the increasing population growth that causes mangrove forest degradation and land conversion into agricultural land, plantations, and infrastructure. The increase in population is a driving force, land clearing for settlements and plantations is a pressure factor (Pressures), land use change is a factor of existing conditions (State), and reduced mangrove land area is part of the impact (Impact). Coastal spatial planning and counseling to reforestation is a response (Response). Land conversion to other uses contributes to this area's continued loss of mangrove land.Keywords: Mangrove; Land Cover; GIS; DPSIR

Abstract

This study aims to analyze the spatial distribution of the population of disaster-vulnerable groups in Bantul Regency in 2022. This study used secondary data from the Central Statistics Agency (BPS) with data on infants, toddlers, children, pregnant or breastfeeding mothers, people with disabilities, and the elderly. The collected data is then processed to determine the density intervals of high, medium, and low vulnerable groups. The study results are presented as a spatial distribution map of the density of vulnerable groups. The results showed that areas with a high density of vulnerable groups were in Kasihan and Piyungan sub-districts. Sites with a moderate density of vulnerable groups are in the Banguntapan, Sewon, Bantul, Jetis, and Imogiri sub-districts. Meanwhile, areas with low density of vulnerable groups are in Sedayu, Pajangan, Pleret, Dlingo, Pandak, Bambanglipuro, Srandakan, Pundong, and Sanden Districts. Mapping the spatial distribution of vulnerable group density can determine areas in Bantul Regency classified as highly vulnerable group density to be prioritized first, then medium to low vulnerable group density. Thus, this research can be helpful for Bantul Regency policymakers in carrying out earthquake disaster risk reduction programs for vulnerable groups referring to the results of spatial distribution maps, and it is hoped that this research can be implemented for other regions in Indonesia.Keywords: Spatial Distribution, Disaster-Vulnerable Groups, Bantul Regency.

Abstract

Collaborative abilities are one of the pillars that students must have in facing the complexity of the world, especially in world complexity, especially in abilities that can be trained by using E-LKPD in learning. Therefore, this research aims to determine the needs analysis for E-LKPD development. This type of research is quantitative and descriptive, using questionnaires, interviews, and observation data collection techniques. The research subjects were students in class XI-10 IPS at SMA Negeri 5 Samarinda. The data obtained was then analyzed using quantitative descriptive analysis techniques. Based on the data analysis, the curriculum requires LKPD as an attachment that must be provided in learning. The material presented in E-LKPD has informative and procedural characteristics. The analysis of student needs shows that 78% of students need  E-LKPD, making it easier for them to understand the material, and 38% of students attract students' learning attention. Regarding the weaknesses of the E-LKPD used during geography learning, it is that the E-LKPD is not in accordance with the meaning of the E-LKPD itself, the E-LKPD is not in accordance with the curriculum used, the E-LKPD used by students has not attracted the students' learning attention. Based on the results of this research can provide an illustration that needs analysis seen from the curriculum aspect, material characteristics, and student characteristics is the main step in developing E-LKPD that is appropriate and innovative based on current needs. Keywords: Need analysis; E-LKPD Bases on Geographical Inquiry; Collaborative Abilities
