Horseshoe crab is an exotic and protected marine organism in Indonesia and is considered as the living fossil animal in the world. IUCN conservation status of Carcinoscorpius rotundicauda and Tachypleus gigas is still Data Deficient, and in Indonesia research on genetic population is lacking, if any. This study aims to reveal genetic diversity of C. rotundicauda and T. gigas populations in Demak, Madura, and Balikpapan coastal waters. This research was conducted by using molecular analysis with genetic markers Random Amplified Polymorphic DNA (RAPD). The primers used in this study were OPB 06, OPG 10, and OPX 03. The results showed that the highest polymorphism of C. rotundicauda was found in Demak (74.6667%) and heterozygosity was 0.2669. Furthermore, T. gigas had the highest polymorphism in Madura (74.3590%) and heterozygosity was 0.25551. Based on pairwise comparison tests, populations of C. rotundicauda and T. gigas in Demak, Madura, and Balikpapan were significantly different (p

Poverty is both a cause and a victim of deteriorating environmental quality. The poor are regarded as very dependent on the environment and natural resources in sustaining their lives so that the environment and natural resources are exploited regardless of their sustainability. On the other hand, environmental degradation causes the poor to get out of poverty. This study aims to (1) analyze the general picture of environmental quality and poverty, (2) analyze the effect of poverty on the environment, (3) analyze the effect of environmental quality on poverty along with other supporting factors in Indonesia 2012-2014. The analytical method used is simultaneous equation with EC2SLS method. The results show that poverty can affect environmental degradation but not vice versa. Exogenous variables that significantly affect the quality of the environment are the growth of the number of poor, economic growth, population density, and literacy rate. Exogenous variables that have significant effect on poverty are economic growth, wage, population density, and literacy rate.

Abstrak: Indonesia semakin mengalami penurunan kuantitas dan kualitas sumber daya alam. Penyebab utama dikarenakan pemanfaatan berlebih dan merusak tanpa tanggung jawab dari beberapa pihak. Berbagai langkah mitigasi yang ditempuh cenderung menguntungkan satu pihak. Diperlukan model pengelolaan yang tepat dan bermanfaat bagi semua pihak. Pengelolaan berbasis masyarakat (PBM) seperti pengelolaan Sasi Laut di Kampung Folley, Papua Barat merupakan salah satu model yang dinilai tepat dilakukan. Sasi sebagai tradisi, diduga mengalami banyak perubahan. Tujuan penelitian ini untuk menganalisis dinamika pengelolaan Sasi Laut Kampung Folley dan dampaknya terhadap penguatan pengelolaan. Hasil penelitian menunjukan terjadi dinamika pengelolaan yang setidaknya melibatkan lima momentum perubahan, yaitu masa pembentukan kampung, intervensi peran agama, introduksi teknologi, keterlibatan pihak eksternal dan penetapan regulasi Kawasan Konservasi Perairan. Unsur pengelolaan yang berubah yaitu batas wilayah, peraturan, pemegang otoritas, hak, sanksi, dan monitoring yang disebabkan faktor internal dan eksternal. Dinamika pengelolaan yang terjadi mengarah pada penguatan pengelolaan Sasi Laut.

Water demand should be balance with water availability. The population of Bogor City was increased every year, so that water demand become increased. Currently, Government of Bogor City only utilizes the Cisadane river as a source for drinking water, but Bogor City has 2 rivers there are Cisadane river and Ciliwung river. So, Ciliwung river can be solution for this problem. Water discharge and rainfall influence water availability. Distribution log pearson type 3 used to predict the water discharge and rainfall and linier regression analyzed the relationship between water discharge (dependent variable) with rainfall as X1 and water level as X2 (independent variable). The result of distribution log pearson type 3 every return period 2, 5, 10, 25, dan 50 years is water discharge and rainfall were increased. Average increase of water discharge every return period is 1.6 m3/s and average increase of rainfall every return period is 251 mm. Partially, water discharge influenced by water level 97.7% and 2% by rainfall. But, = 0.000 < = 0.05. it is mean rainfall and water level cannot be ignored because it can influence water discharge with regression model = -3.01 + 0.000 X1 + 0.202 X2.

This study’s background was based on the prohibition of cantrang’s operation. To reduce impact of this ban, the Government was replacing cantrangs with another fishing gears which are considered more environmentally friendly. In Banyutowo, Pati Residence, “cantrang” was replaced with Gillnet Millennium. This study aims to determine the pattern of fishing season of some of the dominant fish species caught around Banyutowo and to analyze the effectiveness of replacing fishing gear, from cantrangs into gillnet millenium at Banyutowo. The fishing season indeks was analyzed using the moving average method. The types of fish analyzed in this study were the dominant fish caught in the Banyutowo waters with cantrang and gillnet such as Kuniran, Squid, Pari, Manyung, Beloso, Kuro and Tigawaja fish. Analysis of the effectiveness of replacing cantrang with the gillnet millenium in Banyutowo was carried out at the process, and output stages. The results showed that some of the most landed fish in PPI Banyutowo had different fishing seasons. The peak season for fishing in Banyutowo occurs in December (West season) and lowest in July (East season). The evaluation of the effectiveness of replacing cantrang into the gillnet millennium in Banyutowo at the process stage shows ineffective results, and at the output stage shows very ineffective results.

Cajuput is a plant that plays an important role for forest industry development. Its leaves contain essential oil and become one of the non-timber forest products. The productivity of cajuput leaves is affected by certain factors, one of them are the level of land suitability. This study investigated the land suitability for cajuput establishment and its inference on silviculture strategy. Study location was situated in Forest Resort Gubugrubuh, Gunungkidul District. Data collection was conducted in 3 site that converted as the priority site of cajuput plantation namely site 75, site 78, and site 80. We used 6 indicator of land attributes including altitude, slope, rainfall, temperature, soil acidity, and soil organic carbon. The assessment of land suitability was determined by qualitative approach using storie and root square method. The result showed the level of land suitability was classified into N1 (currently not suitable) referring to the storie method, meanwhile it was categorized into S3 (marginally suitable) according to the root square method. This study also discovered the distinctive land attributes which became the limiting factors of cajuput growth in each site. The best silviculture strategies for supporting cajuput development in each site were terrace construction, plant distance management, and fertilization.
