The geological condition of Morotai Island is influenced by small faults and tectonic activity from several major and minor plates that form the subduction zone, are the Pacific plate, the Philippine plate, the Sangihe plate, and the Moluccas Sea plate. This causes Morotai Island to have a high potential for earthquake hazards. South Morotai is the center of government, services, trade and economy on Morotai Island, and has a high potential for earthquakes. Therefore, an analysis of the distribution of seismic vulnerability values in South Morotai was carried out based on mapping as a disaster mitigation effort in South Morotai. The microtremor method uses the H/V spectral ratio analysis technique to analyze the level of earthquake hazard based on the value of the seismic vulnerability index by considering local soil conditions. The ground frequency value (f0) obtained when measuring microtremor is between 0.6 Hz to 0.7 Hz. The amplitude value (A0) in the South Morotai area is around 1.9 – 5.2 times strengthening. The value of the seismic susceptibility index (Kg) in the study area is calculated based on the value of the basic frequency and amplitude with between 5.9 to 44.8. It was concluded that the distribution of a high Kg index and an earthquake prone area was in Darame Village, Muhajirin Village, and Wawama Village with a Kg value > 20. This area is composed of alluvium consisting of gravel, potential mud, and boulders, so it is classified into soft soil type. Less vulnerable areas are in Gotalamo Village, Daruba Pantai Village, and Darame Village

The village, which is located in the Coastal District of Jailolo, West Halmahera, had a considerable impact from the earthquake. This is because the earthquakes that occur are influenced by tectonic earthquakes due to the movement and collision of tectonic plates on land and the seabed. If the collision causes a fault in the seabed, a tsunami can occur. The purpose of this study was to analyze the risk of earthquake disasters in supporting development planning and to produce an earthquake risk map for the coastal area of Jailolo District, West Halmahera. The analytical method used is descriptive quantitative, and the data collection model is a questionnaire with random sampling. The results obtained are in the form of a hazard value using the PGA value and produce the same PGA value, namely > 0.70 gal with a high category for Bobanehena Village, Saria Village, Payo Village, Bobo Village, and Idamdehe Village. The value of vulnerability (physical, social, and economic vulnerability) shows that Bobanehena Village has a high vulnerability index value with a score of 1.9. The capacity index value for the five villages has the same score of 3 and is included in the high class. So that the value of the earthquake risk level with a high class is obtained, namely in Bobanehena Village and Bobo Village. The high level of risk in the two villages is influenced by the frequency of occurrence of earthquakes with high intensity in the area, the impact of losses due to earthquakes is quite high. Earthquake risk reduction efforts will be maximized if a comprehensive earthquake risk assessment analysis is carried out and a commitment from the Government is carried out.

Before it was made into the Aketajawe Lolobata National Park, the forest was a forest that was used by local people to meet their needs and survival in farming. Communities inside and outside can not be separated from the National Park area because in reality these communities have first lived in the area around the forest. This research was conducted with the aim to find out the perception of the Ake Jawi Village Community on the Existence of Aketajawe Lolobata National Park (TNAL). This study used descriptive qualitative method. The data used are primary data and secondary data. The data source is 22 families that directly border TNAL. Data collection techniques are observation and interviews. Respondents were selected by purposive sampling. Data analysis techniques using descriptive qualitative (data collection, data reduction, data display, verification / drawing conclusions).Based on data analysis, namely (1) Perception of a small percentage of people who have a good perception of the existence of a national park that the community considers that TNAL has a positive impact. It is hoped that the existence of a national park will continue to benefit from forest resources and maintain its sustainability for the foreseeable future. The public perception is not good, namely the presence of TNAL, does not provide anything but only reduces the area of their arable land that enters the TNAL area, which makes the community disturbed by the presence of TNAL. This is the case of many Ake Jawi Village respondents who have received elementary and secondary education. (2) The perception of the people of Ake Jawi Village is caused by external factors, namely the low level of education, lack of participation in socialization, lack of experience and lack of community knowledge about national parks and functions for the next life.

Sampah merupakan sisa-sisa aktivitas manusia yang tidak digunakan lagi. Semakin meningkatnya jumah penduduk mengakibatkan meningkatnya volume sampah rumah tangga terutama di daerah perkotaan. Selama ini masyarakat di Kelurahan Tanah Tinggi Barat hanya mengumpulkan dan membuang sampah di pembuangan sampah sementara atau selokan tanpa pengolahan atau pengelolaan, sedangkan daya tampung Tempat Pembuangan Akhir semakin terbatas. Solusi untuk mengatasinya adalah dengan memberdayakan masyarakat dalam pengelolaan sampah skala rumah tangga dengan metode komposting Takakura. Metode pelaksanaan pengelolaan sampah rumah tangga ini mengunakan survey, sosialisasi dengan ceramah dan demonstrasi, program pendampingan serta evaluasi. Pelaksanaan pelatihan Takakura dalam pengelolaan sampah rumah tangga di Kelurahan Tanah Tinggi Barat, Kecamatan Ternate Selatan, Kota Ternate, Provinsi Maluku Utara, dinyatakan berhasil dengan adanya peningkatan pengetahuan warga tentang sampah dari rata-rata 59 % menjadi 96 % setelah sosialisasi. Metode pembuatan kompos ini dapat dilanjutkan secara mandiri oleh masyarakat, maupun dengan program yang melibatkan masyarakat secara aktif dalam pengelolaan sampah dari pihak kelurahan.
