<p>The rapid development of Balikpapan City has an impact on the increasingly high demand for land for urban expansion needs. The expansion of Balikpapan City is more directed towards coastal areas which are dominated by mangrove forests. This study discusses the destruction of the mangrove forest and its causal factors and how conservation efforts are being carried out to maintain sustainability. Mangrove forest damage data obtained through surveys and image analysis using NDVI. While the factors causing the damage to mangrove forests were obtained from observations and interviews with the mangrove center manager of Balikpapan. The results showed that there were many mangrove forests that had rare or already damaged that were spread in the West Balikpapan, North Balikpapan, and East Balikpapan Sub-district. This damage is caused by natural and non-natural factors. Natural factors that cause damage to mangrove forests are pests and sedimentation. The non-natural factors are due to the pollution and the opening of fish ponds. Preservation efforts are carried out by replanting mangroves which are only carried out by the mangrove center and some CSR and environmentalists and do not involve the community at large. These Conditions make the mangrove forest in Balikpapan City threatened its sustainability.</p>
Fieldwork has been widely known to be important in Geography and other disciplines. Fieldwork was described as an outside activity where students can see and hear the geography phenomena in the field. It was also believed that fieldwork was an essential way to gain a better understanding of geographical objects. Some previous research had shown the advantages of fieldwork for students. Combining fieldwork and research was possible to gain students' understanding of disaster risk reduction in the school community especially in the disaster-prone areas. This research aimed to know the effect of fieldwork and research on undergraduate geography education' students understanding of disaster risk reduction in the school community. Students engaged in field work and research activities in the southern part of Klaten Regency Central Java Indonesia, which is vulnerable to various disasters such as earthquakes, floods and landslides. The students were evaluated before and after fieldwork using questionnaires. The result showed that fieldwork and research improved students' understanding of disaster risk reduction.
Spatial thinking can be thought through geography however to teach spatial thinking, geography teachers need appropriate knowledge and perception. The aim of this research was to know geography teacher perception about teaching spatial thinking through geography that viewed by gender. The geography teacher was a senior high school teacher with the consideration that spatial thinking has a deep connection with Geographic Information System (GIS) where GIS is given as geography subject materials to senior high school students. The data collection use a questionnaire to find out geography teachers perception about spatial thinking. The filled questionnaire then scored and analyzed using descriptive quantitative. The result showed that there was no significant correlation between gender and disposition to spatial thinking teaching and learning.
Tujuan dilakukannya pengabdian masyarakat ini sebagai upaya mitigasi bencana banjir di Kelurahan Sewu dengan memanfaatkan teknologi sederhana berupa pembuatan Lubang Resapan Biopori (LRB). Melalui pembuatan LRB ini diharapkan mampu meningkatkan pengetahuan dan sikap masyarakat dalam mengurangi risisko terjadinya bencana banjir. Kegiatan yang dilaksanakan dalam pengabdian ini berupa sosialisasi kepada masyarakat dan demonstrasi pembuatan LRB serta menjadikan LRB sebagai media pembuatan pupuk kompos dari sapah organik. Pengabdian pada masyarakat ini dilaksanakan pada bulan April sampai Juni 2019 di Kelurahan Sewu Kota Surakarta. Luaran dari program ini yaitu menjadikan masyarakat mengerti akan manfaat yang didapat dari pembuatan LRB, selain itu menjadikan masyarakat mengerti bagaimana upaya mitigasi bencana banjir tidak hanya sekedar teoritis, memanfaatkan lahan pekarangan sebagai lokasi LRB.

Natural disaster management efforts are critical, especially in disaster-prone areas. One of them is carried out through education in schools. This study aims to implement disaster mitigation teaching media, analyze and compare the effectiveness rate of these implementations in Klaten Regency. This study was carried out quantitatively using the one-group pretest and posttest design. Respondents were determined by purposive sampling based on the location of schools in areas prone to natural disaster in the Klaten Regency. They consist of 704 students, 291 students were respondents of intracurricular learning, and 413 students were respondents of extracurricular learning. The study results showed that of all instructional media applied in disaster mitigation learning strategies, five learning media had the best effectiveness, namely volcanic mock-ups, animated videos, presentation slides, supplementary books, and posters. Furthermore, there were differences in the effectiveness of implementation, namely in intracurricular including volcanic mock-ups by 37.5%, earthquake video by 24.8%, landslide video by 25.7%, and floods slide presentation by 59.9%. Extracurricular include volcanic eruption video by 41.6%, earthquake video by 27.3%, floods supplementary book by 35.3%, hydrometeorological poster by 46.7%. An interesting finding was that the effectiveness of learning strategies with advanced digital media was not better than other simpler instructional media.
