Judul: Mangrove Rehabilitation Strategy based on Community Perception in Pantai Bahagia Village, Muara Gembong District
Abstrak: Ekosistem hutan mangrove merupakan suatu ekosistem hutan yang memiliki peran penting dalam menunjang berbagai aspek di Desa Pantai Bahagia. Degradasi hutan mangrove di Desa Pantai Bahagia dapat menyebabkan abrasi yang berdampak buruk bagi masyarakat sekitar. Rehabilitasi hutan mangrove perlu dilakukan dengan mengetahui persepsi masyarakat sebagai salah satu faktor penting dalam rehabilitasi lahan. Tujuan dari penelitian ini adalah merumuskan strategi rehabilitasi mangrove di Desa Pantai Bahagia berdasarkan persepsi masyarakat. Hasil penelitian ini menunjukan bahwa masyarakat memiliki persepsi pengetahuan dan sikap yang tinggi terhadap rehabilitasi mangrove. Strategi yang tepat dalam rehabilitasi mangrove oleh BKPH Ujungkrawang adalah strategi WT yaitu mengatasi konflik di dalam kawasan dan meningkatkan kapasitas sumberdaya unit pengelolaan, agar unit pengelolaan lebih siap untuk mengakomodir masyarakat dan juga pihak lain yang telah melakukan kegiatan penanaman dalam rehabilitasi mangrove di Desa Pantai Bahagia.

Abstrak: Conversion of mangrove area into aquaculture land is one of the biggest causes of degradation of mangrove areas. Conversion of mangrove area and the area of ponds which not used again resulted in increasing numbers of mangrove area were damaged and open. In general, reduction of mangrove forests as a result of land conversion have an impact are quite complex, such: the coastline erosion, high tide, flooding due to rain, declining water quality, and in the end lead to a decrease in overall environmental quality. Therefore, environmental management and conservation of mangrove forest ecosystems it is very necessary to make improvement of environmental quality in mangrove areas. Based on those reasons, this study aims to: 1) identify the vulnerability of degradation of mangrove areas in the Village of Muara, Tangerang; 2) identify environmental factors (supporting and inhibiting) that effect on the rehabilitation of mangrove areas in the Village of Muara and formulate the strategy of rehabilitation. The study was conducted in the village of Muara, subdistrict of Teluknaga, district of Tangerang, Province of Banten. The data used in this study consisted of primary data and secondary data. The primary data obtained through sampling, field surveys and interviews. Secondary data were obtained by collecting data and information required from various related institutions. Analyzer which used in this study consisted of: analysis of vegetation, analysis of the vulnerability of mangrove degradation, descriptive analysis of environmental factors, and A'WOT analysis (combined AHP and SWOT) to formulate rehabilitation strategies of mangrove. The results showed that the mangrove areas Muara experienced a high level of vulnerability of degradation based on mangrove vegetation characteristics. Mangrove vegetation in Muara has a level of low density, levels of low species diversity and levels of high dominance. There are six mangrove species which was found in mangrove areas Muara, that is Avicennia alba, Avicennia officinnalis. Rhizophora apiculata, Rhizophora stylosa, Rhizophora mucronata, and Nypa fruticans. Mangrove species with the highest INP present in Rhizophora mucronata. Rehabilitation process of mangrove by revegetation methods are needed, wherein, species of mangrove that are used in revegetation process are local species which the seeds can be found in the mangrove areas of Muara. Physical environmental conditions of mangrove areas in Muara are generally still suitable for of mangrove growth. Rural communities in Muara showed a positive perception and attitude towards mangrove rehabilitation activities that conducted in their village. Based on analysis of the relationship between the factors that conducted in the A'WOT analysis, there are three (3) alternative strategies that be a priority to succeed the mangrove rehabilitation program in mangrove areas of Muara, namely: 1) Promoting Muara as one of the educational tourist attractions for mangrove; 2) Involvement and empowerment of communities in each of the process of rehabilitation and conservation of mangrove; 3) Making the Village of Muara as a supplier of mangrove seedlings for mangrove rehabilitation and conservation in coastal areas of Jakarta

Abstrak: Liquid droplets of nucleic models can be derived equations to estimate the binding energy, binding energy per nucleon, the most stable isotope, and the condition of the occurrence of spontaneous fission. The equations are then converted into a numerical equation form which is then inserted into the MATLAB programming language. Based on the results of the calculations have been carried out in this study, super-heavy nuclei will undergo spontaneous fission in the Z = 135. At Z = 135 the energy needed to create the nucleus undergoing fission or activation energy is very small at around 0:48 MeV. Above Z = 135 the activation energy is negative, it means to form a nucleus with Z> 135 needed some energy. Then at Z = 135 the ratio Z2 / A is 48.86, almost reaching requirement ratio Z2 / A where the nucleic will undergo spontaneous fission is 49. Binding energy per nucleon for super-heavy nuclei up to Z = 200 is about 7 - 5.5 MeV, together with a range of light nuclei are stable. So there may be a super-heavy nuclei are stable at Z <135 and above Z> 135 there will be no stable nucleic
