Multidisciplinary approaches to managing seascapes are increasingly being recognized as best practice and therefore prioritized by conservation agencies. For most coastal areas the strengthening of customary marine tenure, rules and regulations should yield even greater biodiversity and livelihood benefits. Here, we present the conservation planning results from a locally-managed marine area programme initiated by the Government of Aceh, Indonesia, which aimed to empower coastal communities to sustainably and equitably manage marine resources with local government. In 2008 the government established a Marine and Fisheries Task Force to identify priority areas for marine biodiversity (through systematic conservation planning) and coastal communities (through participatory planning). In addition to the existing 264,788 ha of marine management units, systematic planning identified another 53,372 ha. However, the subsequent stakeholder participation phase, involving intensive local consultations, further expanded the locally-managed marine area network by 6,725 ha and to a total of 23 locally-managed marine areas. This combined approach had additional benefits because it generated a strong sense of local ownership. For communities it initiated a process for recognizing their customary claimed areas and resolved overlapping boundaries between neighbouring communities, thereby reducing the likelihood of future conflicts over natural resource use. For government, it provided the basis of a robust governance system, with 34 new or revised decrees being completed and an additional USD 1.6 million being allocated for implementation of locally-managed marine areas. This participatory approach should considerably increase the successful delivery of a sustainable and equitable locally-managed marine area network for Aceh, which has wide application for the South-east Asian region and beyond.
The zonation can be evaluated by observing changes in ecosystem and social status in Wakatobi National Park (Taman Nasional Wakatobi – TNW). Coral reef ecosystem is one of the parameters indicating the effectiveness of zonation system. This study grouped TNW zones into No Take Zone (NTZ – area larang ambil; ZI, ZPB, ZPr) and use zone (UZ – area pemanfaatan; ZPL, ZPU) to determine impact of zonation implementation between 2009 – 2016 on coral reef ecosystem. Three parameters (benthic coverage, fish abundance and fish biomass) were determined by Point Intercept Transect (PIT) and underwater visual census (UVC) methods and all of these data were tested using two-way ANOVA. Hard coral coverage fluctuated between 19 – 32% however, NTZ and UZ had no significant hard coral cover differences (F=2,182, df=1, P=0,14). Abundance of carnivour fish (F=0,53, df=1, P=0,46) and herbivour fish (F=1,98, df=1, P=0,17) were similar between those two zones. Fish bombing and poisoning were two major threats until 2007. However, sand mining and waste management has overcome two previous major threats by 2017. Zonation system and its implementation can be one of mangement effectiveness indicators. Support Wakatobi National Park Authority, it is recommended to apply harvest control rules (HCR), regular patrol and monitoring and stakeholders capacity buiding.

Telah dilakukan penelitian tentang pendugaan mineralisasi emas di Nagari Lubuk Gadang, Kecamatan Sangir, Solok Selatan, Sumatera Barat. Penelitian ini menggunakan metode magnetik dengan tahapan yaitu akuisisi data lapangan, pengolahan data dan interpretasi data. Alat yang digunakan adalah Earth Magnetometer EM2 (Microteslas) AlphaLab.Inc. Perangkat lunak yang digunakan untuk membuat peta kontur adalah software Surfer 11 dan pemodelan 2D menggunakan software Mag2dc. Pengukuran medan magnetik dilakukan pada 50 titik pengamatan dengan luas daerah 670 m2. Hasil penelitian menunjukkan bahwa ditemukan mineral pembawa emas yaitu pirit dengan suseptibilitas magnetik 0.000035 – 0.005 SI, kalkopirit dengan suseptibilitas magnetik 0.000023 – 0.0004 SI, troilit dengan suseptibilitas magnetic 0.00061 – 0.0017 SI, pirhotit dengan suseptibilitas magnetik 0.00046 – 1.4 SI, dan siderit dengan suseptibilitas magnetik 0.0013 – 0.011 SI merupakan mineral sulfida magmatik yang terdapat dalam batuan metamorf dan sedimen. Disamping itu mineral emas juga berasosiasi dengan mineral magnetic yaitu batuan beku (intrusi) yaitu porfiri dengan suseptibilitas magnetik 0.00025 – 0.21 SI. Zona mineralisasi emas diperkirakan terletak pada kedalaman 5 meter sampai dengan 35 meter di bawah permukaan tanah.Kata kunci: Metode magnetik, mineralisasi emas, suseptibilitas.
Face recognition is one of the pattern recognition approaches for the purposes of identifying a person's face with a biometric approach. From this biometric pattern, it can be used as a means to identify the presence of a student. Assisted by the Raspberry Pi, this facial recognition can be done and it can be concluded whether the biometric pattern matches or not. This suitability will be a reference to indicate the presence of a student. So a Raspberry Pi-based Prototype Face Attendance System was made using the Eigenface method. Eigenface is an algorithm that works based on Principle Component Analysis (PCA). Tests were carried out by testing 30 students with a total of 30 photo samples per individual resulting in an accuracy value of 78.85% and error value is 21.15%.
Southeast Sulawesi Province is part of Sunda Banda Seascape and occupies the area of Coral Triangle that has high biodiversity. One of the way to protect areas of high ecological value is by establishing a Marine Protected Area (MPA). According to Goverment Regulation No. 60/2007 section 17. The purpose of this study is to find potential areas to be recommended as core zones, utilization zones and sustainable fisheries zones or other zones. Marxan analysis is a tool used to identify potential sites for the placement of core zones and utilization zones. The target of conserving this location is to protect the habitat of coral reefs, seagrass and mangrove. The proportions of targets used in the Marxan scenario for all three habitats are 30%, 40% and 50%. Result of nine MPAs zonation analysis in Southeast Sulawesi recommendations such as: core zone of MPA Muna Barat is 8% and 13% and utilization zone is 12%; Core zone in MPA Bombana is 8.6% and 5.7% meanwhile the utilization zone of 4.6% and 7.5%; Core zone in MPA Kolaka is Kolaka 10% and 6% moreover utilization zone 7%; Core zone of MPA Central Buton is 3% and 2% while utilization zone 9%; Core zone of MPA South Buton while utilization zone of 6.4% and 6.2%; Core zone of MPA Muna is 10% and 7% besides, utilization zone 8,5% and 23%; Core zone MPA North Kolaka is 4% and 7% while utilization zone is 4% and 49%; core zone MPA Buton is 2.5% and 3% while the utilization zones are 2.5% and 2.6%.
