Profiles and Causes of Urban Poverty in Small Islands: A Case in Ambon City, Maluku Islands Indonesia

Poverty rate is still found to be around two times higher in rural areas. However, excesive urbanization, has increased the number of slums in urban areas. Thus, informal economic sectors and poverty will probably become more urbanized in the future. The main purpose of this article is to study the profiles, causes and livelihood strategies of urban poor households in small islands city. Mixed methods of survey, field observation and focus group discussions including in-depth interview by using questionnaire instruments were used to obtain data from 200 selected households. Findings suggest that the profiles of urban poor households have been identified in terms of social demographic, household economic expenditure and urban poverty rate and living standard indicators. Then, the significant causes of urban poverty have been examined as internal and external factors. Internal factors are cultural and structural-including the number of family members, women-headed household and poverty status. External factors are geographical poverty traps, including distance to city center, sanitation status and misused of government policy on rice for the poor program. Livelihood strategies of urban poor households are occupational multiplicity to reduce risks and uncertainty.

PEMANFAATAN EKSTRAK DAUN CENGKEH (Syzygium aromaticum L.) SEBAGAI HERBISIDA ALAMI TERHADAP PERTUMBUHAN GULMA RUMPUT TEKI (CYPERUS ROTUNDUS L.)

Background: Clove is a spice native plants Maluku Islands, and has been traded and cultivated for generations in the form of people's plantation. Separation of chemical constituents of clove showed that clove leaves contain saponins, alkaloids, flavonoid glycosides and tannins. Flavonoids are one of the types of compounds that are toxic / residues, the sugar bound compound from the flavonoids. Flavonoids have distinctive properties that is a very sharp odor, bitter taste, soluble in water and organic solvents, and easily decompose at high temperatures.
 Methods: This study was conducted in February-April of 2015 at the Laboratory and Greenhouse biology education Pattimura University. This research is a lab experiment. Clove leaf extract obtained by polar solvent is macerated with ethanol 96% and then applied to the growth of weeds sedges. Clove leaf extract concentration used a 5%, 10%, 20%, 50% and control.
 Results: There is a natural herbicide effectiveness of clove leaf extract at a concentration of 50%, which can be used as an alternative to inhibit the growth of tall weeds sedges.
 Conclusion: The higher the clove leaf extract given against weeds sedges will increasingly serve to inhibit weed sedges as measured by plant height, phytotoxicity, fresh weight and dry weight of weeds sedges.

Analysis of Ocean Wind Energy Density around Sulawesi and Maluku Islands with Scatterometer Data

Abstract The aim of this research was to optimize the utilization of Indonesian ocean wind energy potential especially around Sulawesi and Maluku Islands through mobile floating structure (MFS). The wind data used for analysis are scatterometer data for one year period which is from January to December 2008 collected by QuikScat satellite. Weibull distribution with two parameters was used to represent the wind model. Several methods were used to compute the distribution parameters which are linear regression method (LRM), maximum likelihood method (MLM) and moment method (MM). The obtained parameters are used to compute the energy density of the sea areas around the islands.

Ladies in stripes: taxonomic confusion in a potential mimicry complex among Wallacean Coccinellidae (Coleoptera: Coccinellidae).

Two species of ladybird beetles, one belonging to Phrynocaria Timberlake (Coccinellni) and the second to Chilocorus Leach (Chilocorini) collected by R.A. Wallace in the Maluku Islands (Indonesia) have identical body size and colour pattern with longitudinal stripes on elytra. Their external features were so similar that G.R. Crotch included both of them in the type series of Chilocorus wallacii Crotch, 1874. The specimen designated as the lectotype of Chilocorus wallacii belongs to Phrynocaria. Coelophora wallacii Crotch, 1874 is also transferred to Phrynocaria (new comb.) and becomes senior homonym and Phrynocaria crotchi new name is proposed for the secondary junior homonym. Chilocorus crotchi sp. nov. is described for the taxon misidentified as Chilocorus wallacii Crotch.

Local Community Resilience in the Context of Global Climate Change: A Case from Maluku Indonesia

This study is a vulnerability and at the same time resilience study using qualitative method. The study aims to identify the locality of the climate change phenomenon, analyze vulnerability and appraise community resilience. The method used is the ‘historical case method', a study method combining the historical-sociological method (structural history) and sociological history (process history), a qualitative method under the umbrella of the constructivism paradigm. The study results in several findings. Climate change significantly has caused resilience in communities that depend on natural resources. Vulnerability triggered by the negative impact of climate change can be reduced by adaptation so the community will be resilient even with limited resilience due to the high dependency on natural resources. The most important factor in creating community resilience is local institutions' role that facilitates the adaptation. The success of climate change adaptation is determined by the existence and functionality of these local institutions. The stronger and rooted the local institutions the bigger the opportunity for success for the community in adapting to climate change. On a contrary, the weaker and

Moluccan Cyberactors: Religion, Identity and the Internet in the Moluccan Conflict

Tulisan ini membahas cyberspace dan konflik di Maluku untuk memperlihatkan sumbangan bagi cyber anthropology dan analisis mekanisme yang rumit pada situasi di Maluku. Konflik Maluku tidak cuma berlangsung pada tingkat lokal dan nasional, tetapi juga di cyberspace .Tampilan-tampilan di cyberspace sejajar dengan garis-garis agama sehingga memperkuat kesan perang agama antara umat Kristiani dan masyarakat Muslim. Internet menyediakan sarana bagi kelompok-kelompok yang bertikai untuk mengedepankan pandangan mereka mengenai konflik. Hal yang terpenting untuk kajian ini adalah paparan-paparan Internet dari kelompok-kelompok dan orang-orang yang langsung terlibat di dalam konflik, karena mereka mengakui memberikan informasi tangan pertama. Informasi itu membentuk persepsi konflik di luar Maluku dan di dunia internasional. Studi ini memfokuskan pada strategi-strategi dan argumentasi yang dipakai oleh kelompok-kelompok bertikai di Internet untuk menggambarkan pandangan mereka terhadap realitas, mengkonstruksikan komuniti-komuniti ( communities ) dan identitas-identitas mereka yang representatif. Lebih jauh, peran presentasi dalam konflik dan juga peran agama di dalam presentasi-presentasi itu juga diteliti. Webpage , milis dan newsletter terpilih yang mewakili pihak Kristen dan Muslim dianalisis untuk menunjukkan proses konstruksi itu. Setiap kelompok menggunakan bermacam-macam strategi-strategi dan modus-modus komunikasi Internet dan argumentasi teks dan visual untuk mengejar proyek identitas masing-masing. Materi-materi diambil baik dari cyberspace maupun dari konteks lokal Maluku, sehingga mengaburkan batas-batas antara realitas dan virtualitas.

Social Security in Comparative Perspective: Moslem Moluccans in the Netherlands and on Ambon - a Research Note

Keamanan sosial merupakan satu bidang yang kini banyak menjadi perhatian ahli antropologi hukum. Dalam artikel ini, penulis menyajikan hasil penelitiannya tentang studi perbandingan pada sistem-sistem keamanan nasional dari penduduk Maluku Tengah yang memiliki latar belakang kebudayaan dan agama yang sama, tetapi yang bermukim di dua Negara yang berbeda: Indonesia dan Belanda. Keamanan sosial mengacu pada mekanisme yang menjamin diperolehnya kesempatan untuk hidup yang layak, baik bagi orang-orang dewasa yang sehat dalam satu komuniti maupun bagi mereka yang tidak dapat menyajikan hal itu untuk dirinya sendiri. Dalam artikel ini penulis menunjukkan bagaimana bentuk-bentuk keamanan sosial dalam komuniti yang berbeda terwujud karena pengaruh kondisi sosial dan ekonomi yang berbeda pula.

Legal Pluralism in the Netherlands, the Case of Moluccan Pela Law

Pela adalah salah satu hukum adat di Indonesia, tepatnya hukum adat yang ada di Kepulauan Maluku yang berlaku pada orang-orang Maluku. Ada dua peneliti yang telah mengadakan penyelidikan secara mendalam tentang pela ini, yaitu C. Cooley dan D. Bartels. Cooley mengemukakan bahwa pela adalah suatu ikatan yang dilembagakan mengenai persahabatan atau persaudaraan antara semua penduduk pribumi dari dua desa atau lebih, yang dibentuk oleh nenek moyang menurut keadaan tertentu dan membawa kewajiban-kewajiban tertentu untuk semua pihak yang terkait didalamnya. Kewajiban ini penting dalam definisi ini mengenai eksogami desa. Bartel meninjau pola ini dari sisi sosialnya.[...] Aplikasi dari hukum adat pela dalam masalah perkawinan ( intermarriage taboo ) menimbulkan persoalan di antara para generasi muda Maluku di Negeri Belanda. Hal ini selanjutnya mengakibatkan konflik antara generasi tua dengan generasi muda. Di Negeri Belanda sendiri terdapat pluralisme hukum, ialah hukum yang resmi dan hukum yang kurang resmi yang berlaku diantara berbagai subgolongan yang ada. Salah satu subgolongan yang menerapkan hukum demikian adalah golongan pendatang Maluku di Negeri Belanda yang menerapkan adat pela dalam kelompok masyarakat mereka sendiri.

Birds Diversity in Tayawi’s Watersheed Area Aketajawe-Lolobata National Park

Aketajawe-Lolobata National Park was selected as one of conservation areas in Indonesia due to its important roles to preserve wildlife natural resources and its unique ecosystem. Our research on fauna diversity was designed to identify bird species diversity that inhabited Tayawi’s watershed within the Aketajawe-Lolobata National Park in North Maluku. We explored the area by using transect method; species identification was carried out by visual and vocal encounter. Fifty five bird species were identified and they belong to 25 families. Among them, 17 species were identified as endemic to Maluku and Halmahera islands. Based on our analysis and field observation, these areas had low fauna diversity. We suspected that illegal logging and hunting might have caused a rapid decrease of the bird population in Tayawi’s watershed area. These can be a serious threat if it is not well-anticipated. Therefore, urgent need is required to discontinue the activities of illegal logging and hunting.

Seismic structure and ultra-low velocity zones at the base of the Earth’s mantle beneath Southeast Asia

We constrain seismic structure and ultra-low velocity zones near the Earth’s core-mantle boundary (CMB) beneath Southeast Asia. We first determine the average shear-velocity structure near the CMB in the region based on travel-time analysis of S, ScS, P and ScP phases. We then map seismic scattering in the lowermost mantle using the PKP precursors observed at the USArray. The inferred average shear-velocity perturbations in the lowermost 200km of the mantle range from about −6% to 6%, and exhibit a complex geographic distribution of alternate low- and high-velocity patches adjacent to each other, surrounded by a high-velocity anomaly in the south. The inferred strong seismic scatterers exhibit a crescent shape distributed from the South China Sea to the Maluku Islands and coincide with the westernmost low-velocity patch, suggesting that the strong scatterers represent ultra-low velocity zones (ULVZs). We suggest that the seismic structure in the region likely results from a complex interaction between a downwelling and a low-velocity region near the CMB. The downwelling (the high-velocity patches) displaces the low-velocity region into many low-velocity patches and pushes the ULVZs to the edge of the low-velocity region.

Le giroflier de Madagascar : une introduction réussie, un avenir à construire

Introduit à Madagascar au début du 19e siècle, le giroflier est originaire des îles Moluques en Indonésie. Malgré la sensibilité de l’essence aux risques météorologiques, tels les cyclones, et aux attaques d’un parasite local, andretra, et malgré la production variable de clous de girofle d’une année sur l’autre, son adaptation aux conditions écologiques de la côte Est de Madagascar, notamment dans la région d’Ana- lanjirofo, est remarquable. Très vite adoptée par les paysans (certains venus s’installer mais la plupart autochtones), ceux-ci l’ont intégrée dans leurs systèmes de culture en complément aux cultures vivrières (riz, surtout) et de rapport (café et vanille). Aujourd’hui, le marché du clou de girofle est une source de revenus réguliers pour les ménages et leur assure la sécurité ali- mentaire. Le giroflier donne deux produits de grande valeur économique, le clou de girofle, le bouton floral séché, et l’huile essentielle de girofle produite par distillation des feuilles, dont Madagascar est le premier exportateur mondial. Avec la vanille, les produits du giro- flier représentent les premiers produits agri- coles d’exportation, parfois les deuxièmes, de Madagascar. Les clous de girofle s’exportent surtout en Indonésie, où ils entrent dans la fabrication d’une cigarette locale appelée kre- tek. Un petit volume s’exporte vers les pays du nord sous forme d’épice. L’huile essentielle de girofle est distillée dans une multitude d'alam- bics rudimentaires dans toute la région de pro- duction. La qualité de l’huile essentielle dépend de sa teneur en eugénol, molécule mise en œuvre dans de nombreux secteurs éco- nomiques, dont l’industrie des cosmétiques, la pharmaceutique humaine et vétérinaire et l’in- dustrie alimentaire. Le giroflier de Madagascar semble représenter un exemple d’intégration réussie d’une nouvelle culture dans un système de cultures existant. Cependant, les plantations de girofliers vieillissent et les conditions de leur renouvellement ne sont pas pleinement pré- sentes. Alors que le marché du clou de girofle dépend fortement de la demande indoné- sienne, les perspectives sont prometteuses sur le marché mondial des épices et des produits contenant de l’eugénol. De ce fait, les pratiques actuelles et les possibilités d’adaptation et de développement du secteur Malgache de la girofle doivent être étudiées de près pour assu- rer l’équilibre futur entre les marchés et les besoins des paysans en termes de gestion de la ressource et de sa valorisation.

Ina sua, a fermented salted fish product from central Moluccas

Ina sua is a traditional fermented salted fish product originating from Central Mollucas (Teon, Nila, Serua islands), which is processed by fermentation at room temperature during a certain period. There is little or no research on the characteristics of microbial and chemical aspects of this process. Therefore the current research was performed in a laboratory in order to analyse the microbial and chemical characteristics of this product collected from traditional fishermen. The results showed that the composition of bacteria consisted of Bacillus sp.(59.6%), Propionibacterium sp. (17.3%), Leuconostoc sp. (13.5%), and Lactobacillus sp. (9.6%), while the chemicals included soluble protein, peroxide value, and total value acid increased during storage for 12 weeks at room temperature, while pH value of the product varied between 5.58 and 5.93.

Indonesian rainfall variability observation using TRMM multi-satellite data

It is important to understand the characteristics of Indonesian rainfall within the world’s climate system. The large rainfall in the Indonesian archipelago plays an essential role as a central atmospheric heat source of the Earth’s climate system throughout the year. Monthly rainfall satellite data, measured by the Tropical Rainfall Measuring Mission (TRMM) 3B43 over the course of 13 years, were employed to analyse monthly means, total means, maximum and minimum variability, standard deviation, and the trends analysis of Indonesian rainfall variability. The rainfall estimated from satellite data was then compared to the rain gauge data over the Indonesian region to determine the accuracy level. The results show that oceans, islands, monsoons, and topography clearly affect the spatial patterns of Indonesian rainfall. Most high-rainfall events in Indonesia peak during the December–January–February (DJF) season and the lowest rainfall events occur during the June–July–August (JJA) season. Those conditions are associated and generated with the northwest and southeast monsoon patterns. High fluctuations between maximum and minimum monthly rainfall data of over 400 mm month−1 occur over Jawa (Java) Island, the Jawa Sea, and southern Sulawesi Island. A high annual and monthly rainfall typically occurs throughout Indonesia over island areas. The trend analysis shows an increasing trend in rainfall from 1998 to 2010 in Kalimantan, Jawa, Sumatra, and Papua. Decreasing rainfall trends occur along the west and south coast of Sumatra, eastern Jawa, southern Sulawesi, Maluku Islands, western Papua, and Bali Island.

The effect of artificial and natural baits on the capture of tuna hand line around the Molucca Sea

Tuna hand lines have been used by fishermen to catch big pelagic species. Most of the fishermen still used natural bait in their catching operation, and just a few of them who used artificial bait. Therefore, the objective of this research was to study the effect of artificial bait toward the capture of tuna hand line. The artificial bait which been used in this research was non comercial bait, made from a plastic bag with silver color. The natural bait that been used was fish meat. This research was done by descriptive method based on case study; worked on October 2012 until January 2013 in Molucca Sea; hand line with artificial bait caugth 113 fish and with natural bait 67 fish. Analysis of t-test showed that t0 = 4,55 > t0,05;5 = 2,080; which means that the use of artificial bait could affected the catch of tuna hand line© Pancing ulur tuna biasa digunakan oleh nelayan untuk menangkap ikan pelagis besar. Umumnya mereka masih menggunakan umpan alami; masih sedikit nelayan yang menggunakan umpan buatan dalam operasi penangkapannya. Oleh karena itu, penelitian ini bertujuan untuk mempelajari pengaruh penggunaan umpan buatan terhadap hasil tangkapan pancing ulur tuna. Umpan buatan yang digunakan adalah umpan non-komersial (buatan sendiri) yang terbuat dari bahan plastik berwarna perak mengkilat, sedangkan umpan alami yang digunakan adalah daging ikan. Penelitian ini dilakukan dengan metode deskriptif yang didasarkan pada studi kasus yang dilaksanapan pada bulan Oktober 2012 sampai Januari 2013 di perairan Laut Maluku. Pancing ulur tuna dengan umpan buatan menangkap 113 ekor dan dengan umpan alami menangkap 67 ekor. Uji-t menunjukan bahwa t0 = 4,55 > t0,05;5 = 2,080 yang berarti bahwa penggunaan umpan buatan berpengaruh terhadap hasil tangkapan pancing ulur tuna©

Community structure of nudibranchs (Gastropoda) at Coastal Waters of Waleo Village (Mollucas Sea) and Kalasey Village (Manado Bay, Sulawesi Sea)

Nudibranchia are mollusks without a shell. They are simultaneous hermaphrodites and are carnivores while some of them are cannibals. Nudibranchia are frequent occupants and foraging on coral reefs. The study was conducted at two locations, namely Waleo Village Waters representing the waters of Mollucas and Sulawesi Sea was represented by Kalasey Village. The difference in the location of the two waters is expected to affect the existence of community structures. The present study includes diversity, richness, evenness, dominance and similarity. A line transect was used to collect data. We found 84 individuals from both study sites representing 8 species of Nudibranchia, which fall into 4 genera and 3 families namely, Pteraeolididae, Phyllidiidae, and Chromodorididae. The most common family was the Phyllidiidae. The similarity value at both locations was 54.5%© Penelitian tentang struktur komunitas gastropoda nudibranchia telah dilakukan di dua lokasi yaitu Desa Waleo (Laut Maluku) dan Desa Kalasey (Laut Sulawesi).
