ABSTRACTBreakwater is a small structures designed to protect coastal area from extremely sea waves exposure. The breakwater has been used in many coastal area at various town in Papua include Manokwari Regency, West Papua Province. Breakwaters designed at Manokwari has been reduce the intensity of wave action in inshore waters. Moreover, the breakwater also reduce coastal erosion and provide safe harbourage for local fishing. Same with the others, the breakwater on the coast of Manokwari also contact with the substrate directly, which is a habitat for Polychaeta. The lack of research data and information on Polychaeta in the Papua Sea encourages this research must be done. The purpose of this research is to identify the spesies of Polychaeta and analyze the impact of breakwater to the community structure of Polychaeta. This research conducted on March to June 2018 focus on six station of five beach with breakwater at the coastal of Manokwari, West Papua i.e. Abasi, Pasir Putih, Wosi, Andai and Mansinam Island. The line transect quadran method were use to collect sample of the Polychaeta. Total 64 sample of Polychaeta was collecting and identified.  Approximately 17 spesies of Polychaeta (i.e. seven orders, nine of families and 14 genera) already identified. Based on ANOVA and BNt tests, the breakwater development has significantly impacte to the structure community of Polychaeta on the coastal of Manokwari. ABSTRAKBreakwater atau pemecah gelombang merupakan struktur kecil yang didesain untuk melindungi area pesisir pantai dari paparan gelombang air laut yang ekstrim. Sama dengan lainnya, breakwater di pesisir pantai Manokwari juga bersentuhan langsung dengan substrat, yang merupakan habitat cacing laut, Polychaeta. Minimnya data penelitian dan informasi tentang Polychaeta di laut Papua mendorong penelitian ini dilakukan dengan tujuan mengidentifikasi spesies Polychaeta dan menganalisa dampak yang ditimbulkan dari breakwater terhadap struktur komunitas cacing taksa cacing laut ini. Penelitian ini dilaksanakan pada bulan Maret hingga Juni 2018 yang dipusatkan pada enam stasiun di lima pantai yang terdapat breakwater, yaitu pantai Abasi, Pasir Putih, Wosi, Andai dan pantai Pulau Mansinam. Garis transek kuadran sebagai metode pengambilan sampel Polychaeta. Sebanyak 64 sampel telah dikoleksi dan berhasil dikenali 17 spesies Polychaeta yang terbagi dalam tujuh ordo, sembilan familli dan 14 genus. Berdasarkan uji ANOVA dan Uji BNt menunjukan keselarasan pembangunan breakwater berdampak signifikan terhadap struktur komunitas Polychaeta di pesisir pantai Manokwari.

Abstract . Dynamic environment in coastal area, especially due to coastal erosion process, has negative impact on human environment. Sayung coastal area, located in Central Java-Indonesia, has experienced severe impact of coastal erosion. As the result of the coastal erosion, hundreds of settlement located in coastal area has been destructed. Moreover, fishponds as the land use dominated in the coastal area also has been severely destroyed. Besides the coastal erosion, increasing of inundated area due to sea level rise also threaten the local community. Although devastating impact suffering the coastal area, the people of Tambaksari, as the part of Sayung area, decided to live and adapt with the coastal erosion. This paper aims to identify the coastal erosion and understand adaptation strategies held by the local community related to reduce the impact of the coastal erosion. Based on this research, various adaptation strategies has been identified, namely (1) Planting mangrove alongside the shoreline, (2) elevating the ground level, (3) building staged house, (4) utilizing deep well for freshwater supply, (5), maintaining social interaction with mainland community, (6) Collecting fish from the mangrove as the food, and (7) changing work into the tourism sector.

One of the animals that are easy to find is a bird. Based on data about the increase in the number of bird species, it can be ascertained that these animals can be found in every region in Indonesia, with diverse species and even species that are endemic to a certain area. West Papua is one of the regions in Indonesia which is rich in various species of birds, including Cendrawasih which can also be found in the Natural Forest of Malagufuk Village, Klayili District, Sorong Regency. Based on information from the surrounding community, several types of Cendrawasih are often seen in the natural forests of Malagufuk Village, but their diversity and population are not known with certainty. This study aims to determine the diversity of species and population of Cendrawasih birds in the natural forest of Malagufuk Village, Klayili District, Sorong Regency, West Papua. Thus, the results of this study are expected to be a source of data in the context of preserving and protecting the existing Cendrawasih species. Data collection on the species composition and population of Cendrawasih was carried out using the Line Transect method by making 10 observation lines with a line length of 500 m each and a distance between lines of 100 m. The results showed that there were found 3 spesies of Cendrawasih with estimated populations and densities as follows: Cendrawasih Kuning Kecil (Paradisaea minor) had an estimated population of 7.48 individuals with a density of 2.93 individuals / ha; Cendrawasih Raja (Cicinnurus regius) has an estimated population of 5 individuals with a density of 1.67 individuals / ha; and Toowa Cemerlang (Ptiloris magnificus) had an estimated population of 2.22 individuals with a density of 0.74 individuals / ha. When the research was carried out, it was seen that the three types of Cendrawasih used several types of trees as places for activities (playing or dancing), namely Matoa (Pometia coreacea), Merbau (Intsia bijuga), Damar (Agathis dammara). Beringin (Ficus benjamina), and Pala hutan (Myristica sp) with tree heights above 20 m.

Indonesia has embarked fiscal decentralization policy for more than 20 years. While the results are still varying across the regions, governance seems to be one of the causes of existing condition. The study analyze the impact of governance to the link between General Allocation Fund (DAU) and Gross Domestic Product (GDP). Employing governance indicator from kemitraan in 2012, this research compares the relationship within good governance province (east Java) and bad governance provinces (Papua and West Papua). This study results argue that governance matters in achieving fiscal decentralization objectives. Another result also confirm that education level has positive connection fiscal decentralization outcomes only in province with good governance indicator. Indonesia telah menerapkan kebijakan desentralisasi fiskal lebih dari 20 tahun yang lalu. Dengan hasil yang masih bervariasi belum sesuai di berbagai daerah. Beberapa studi mengindikasikan bahwa perbedaan ini disebabkan oleh faktor tata kelola dari masing-masing pemerintahan daerah. Studi ini menganalisis pengaruh dari tata kelola terhadap hubungan antara Dana Alokasi Umum (DAU) dan Produk Domestik Bruto(PDB). Menggunakan data indeks tata kelola dari kemitraan.or.id pada tahun 2012, penelitian ini menguji pengaruh variabel tata kelola pada daerah dengan indeks tata kelola baik (Jawa Timur) dan daerah dengan tata kelola buruk (Papua dan Papua Barat). Hasil studi menunjukkan bahwa tata kelola memiliki pengaruh dalam mencapai tujuan desentralisasi fiskal. Hasil yang yang lain juga mengkonfirmasi bahwa tingkat pendidikan memiliki pengaruh signifikan bagi PDB hanya pada daerah yang memiliki tata kelola yang baik.

<p><em>On the one hand, the coastal area promises abundant natural resources, but on the other hand, there are potential threats of disaster for the people living in that area. Coastal erosion or abrasion is a threat/danger that harmful to communities in coastal areas in Indonesia. One of the areas affected by abrasion in Indonesia is Rembang Regency. This study attempted to analyze the physical and social impacts of abrasion in the Rembang Regency. This study was conducted qualitatively by utilizing Ikonos High-Resolution Satellite Imagery, field surveys, and interviews as the basis for the analysis of the impact of the abrasion disaster. Respondents in this study were communities and government officials in areas affected by abrasion which were determined by purposive sampling technique. The results of the data analysis show that the physical impacts of abrasion are classified into four categories, namely heavy damage, moderate damage, minor damage, and no damage, while the social impacts are in the form of psychological, sociological, and economic disturbances which have implications for decreasing welfare. Therefore, an in-depth analysis is needed to determine the abrasion disaster management policy in Rembang Regency.</em></p>
