Identification of Mangrove Forest Damage, and Effort to Conservation in Balikpapan City, East Kalimantan, Indonesia

<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>

The Accessibility Analysis of COVID-19 Referral Hospitals to The Location of Fundamental Student

The Covid-19 pandemic that occurred in all parts of the world has had an impact on the various sectors. Not only in the economic sector but also in the educational sector. Until Month June Year 2020, the Indonesian government had carried out a new-normal policy. The purpose of the study was to analyze the affordability of the Covid-19 referral hospital to the position of students during the new-normal era. The affordability could be observed by the distance traveled by students to the nearest Covid-19 referral hospital. This study used the OD matrix layer from ArcMap 10.3. The sample used in this study was 87 students with 11 Covid-19 referral hospitals in East Nusa Tenggara Province. Based on the research results in the form of maps produced, showed that from 87 students observed, only 59 or 67.82% could reach the Covid-19 referral hospitals. Meanwhile, the other 28 students or 32.18% couldn’t be reached by the hospitals. The amount of students observed, located less than 15 km from the Covid-19 referral hospitals were 35 or 40.22% from the total of 87 students. The hospital which students refer to based on their location was the WZ. Yohanes hospital.

Application of The E-Learning Model in Earthquake Learning to Improve Students' Understanding of Earthquake Disaster Preparedness

<p><em>This study aims to describe the application of e-learning in improving students' understanding of earthquake disaster preparedness. This study used a quasi-experimental design with an equivalent time series type. The research sample was taken of grade 10 Senior High School 5 Banda Aceh with a non-probability sampling method. The stage of this research is that students are given a pre-test to see their initial level of understanding before being given a treatment, then students are given a treatment in the form of earthquake preparedness learning through the e learning model. the understanding of students after participating in learning with the e learning model has increased by 14.44 %. As for the n-gain value is 0.54 (moderate criteria), the N-gain value indicates that learning with the e-learning model is effective in improving students' understanding of earthquake disaster preparedness. based on research data analysis it was seen that students' understanding of earthquake disaster preparedness had increased compared to before. Meanwhile, related to the effectiveness of learning, based on data analysis, it was found that learning earthquake disaster preparedness using the e-learning model was effective in increasing students' understanding of earthquake disaster preparedness.</em></p>

Enhancing Farmer’s Well Being Through the Agriculture Land Provisions in West Nusa Tenggara

<p><em>While carrying out its essential duties to provide adequate foods for people, the agriculture sector is facing sustainability issues. The study presents a case study of West Nusa Tenggara (NTB), whereby an increase of urban expansion activities has begun to create a centrifugal force to the province that is popularly called as the granary of Indonesia. Urban settlements slowly leapfrogged to the outskirts and reduced the size of prime agricultural lands. Moreover, existing planning policies were unable to control the situation and many farmers leave their jobs because the setback of farmers wellbeing. The size of agricultural land is highly influential towards farmer motivation to stay engaged in the farming sector. Applying qualitative methods, this study examined the minimum area of agriculture land (focusing on paddy field) to promote farmer’s well-being following three steps of the analytical framework: total agricultural production estimation, the average well-being estimation, and the prediction of minimum land provision for the average well-being. After all, one of the key important findings reveals that</em><em> </em><em>the average of minimum agricultural land to ensure famers wellbeing for the whole NTB Province is </em><em>0.74 Ha.</em> <em></em></p>

Mapping The Capacity of The Mosque in Spatial Review in East Bogor Sub-District

<p><em>The increasing awareness of Muslims about Islam encourages them to participate in activities carried out by mosque administrators, this has an impact on the capacity of the mosque space. This study aims to determine the distribution of mosques and their capacities based on the population in East Bogor Sub-District. Data collection is done by using spatial data to support decision making to increase efficiency and time accuracy by using the buffering method. Where the buffer is to determine the optimal radius assuming distances of 100 m, 250 m, 500 m, and 1000 m. The results showed that in East Bogor District there were 73 mosques and the capacity of the mosques was 33.72% of the total population of 106,029 people.</em></p>
