Abstract

Reclamation activities conducted in the Bay of Manado, at the seaward side on Pierre Tendean Street (Boulevard), has changed the face of the city of Manado including the coastal area. The purpose of this study was to determine whether the realization of reclamation activities seen were as planned. The second purpose was to determine the appropriate policy strategy to ensure that the utilization of reclaimed land can be optimal. The data was collected through observation to compare actual conditions with the original plan. For policy options, SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis was used. The study revealed that there are changes from the original plan, such as the extent of the area was originally planned 1185 m2, but the actual area was 781.305 m2. Based on the results of the SWOT analysis, the most appropriate policy option adopted is to optimize the role of land reclamation as one economic driving force in the city of Manado. These include the completion of a number of legal problems in reclamation© Kegiatan reklamasi yang telah dilakukan di Teluk Manado, memanjang dari Utara ke Selatan Kota Manado ke arah laut telah merubah wajah Kota Manado termasuk di dalamnya tata ruang dan pemanfaatan lahan yang baru di wilayah pesisir. Penelitian yang telah dilakukan bertujuan untuk mengkaji realisasi aktual dari kegiatan reklamasi apakah sesuai dengan peruntukannya, menentukan strategi kebijakan yang tepat dari pemanfaatan lahan reklamasi agar dilakukan dengan optimal dan ramah lingkungan. Pengumpulan data telah dilakukan secara deskriptif melalui observasi dan pengamatan lapangan untuk membandingkan kondisi aktual dengan rencana semula. Sebagai pilihan penentuan kebijakan penelitian, data dianalisis dengan menggunakan analisis SWOT (Strengths, Weaknesses, Opportunities, Threats). Hasil penelitian mengungkap bahwa adanya perubahan pemanfaatan dari rencana awal luasan kurang lebih 1.185.000 m2, menjadi luasan yang terealisasi sampai saat penelitian dilakukan mencapai luas kurang lebih 781.305 m2. Hasil analisis SWOT menunjukkan bahwa kebijakan Pemerintah Kota Manado harus konsisten dalam menetapkan perijinan, dengan tidak merubah fungsi lahan dan lingkungan pesisir. Dampak positif yang ditimbulkan dalam rangka mengoptimalisasi pemanfaatan lahan reklamasi sebagai salah satu lokasi yang dapat meningkatkan perekonomi dan pendapatan daerah, penyerapan tenaga kerja di Kota Manado. Kebijakan perubahan fungsi dan penambahan luas lokasi yang tidak sesuai dengan perencanaan awal dapat berdampak pada masalah hukum di wilayah pesisir©

Abstract

Indonesia’s mangrove forest is decreasing. Factors affecting this condition are excessive utilization for livelihood and market demand without considering its sustainability for the future. As a result, mangrove forest degrades year by year. The present study aimed to analyse which stakeholder is the priority for mangrove ecosystem management in the city of Sorong, West Papua, Indonesia, and which factors are the priority for sustainable management. Primary data were collected using questionnaire with interview technique and were analysed using Expert Choice 11 software. The result showed that local government was the stakeholder possessing major priority in management which was supported by others (community and NGO), and the ecological factor was the priority in management, while the economic, social, and institutionalfactors were the supporting factors for sustainability. Luas hutan mangrove di Indonesia sedang mengalami penurunan. Faktor yang mempengaruhi kondisi ini, yaitu pemanfaatannya secara berlebihan untuk memenuhi kebutuhanan hidup maupun permintaan pasar tanpa mempertimbangkan keberlanjutannya di masa depan. Sebagai akibatnya tutupan hutan mangrove semakin berkurang dari tahun ke tahun. Penelitian ini bertujuan menganalisis stakeholder manakah yang menjadi prioritas dalam pengelolaan ekosistem mangrove di Kota Sorong, Papua Barat, Indonesia, dan faktor manakah yang menjadi prioritas dalam pengelolaan secara berkelanjutan. Data primer dikumpulkan menggunakan angket dengan teknik wawancara, dan kemudian dianalisis menggunakan software Expert Choice 11. Hasil penelitian menunjukkan bahwa stakeholder Pemda merupakan prioritas utama dalam pengelolaan ekosistem mangrove dan ditopang oleh stakeholder lainnya (Masyarakat dan LSM), dan faktor prioritas dalam pengelolaan adalah ekologi, sedangkan faktor ekonomi, sosial, dan kelembagaan merupakan faktor pendukung untuk terciptanya pengelolaan ekosistem mangrove yang berkelanjutan.

Abstract

High concentrations of chlorophyll-a can be used to predict where fish gather. On the other hand, tropical cyclones are one of the triggering factors for vertical stirring and upwelling that cause fertility of waters. The Sangihe Island area is not an effective area for the formation of tropical cyclones. However, due to its geographical location with a tropical cyclone area and trajectory, the potential for disturbances caused by cyclones is impactful on Sangihe Island. The distribution of wind speed, salinity, sea surface temperature and chlorophyll-a concentration can be detected by satellite remote sensing imagery. This study aims to analyze the impact of Tropical Cyclone Amang on the variability of wind speed, salinity, sea surface temperature and on the concentration of chlorophyll-a in Sangihe Island. This study useswind speed, salinity, sea surface temperature and chlorophyll-a data during the Amang Tropical Cyclone (January 6-27, 2019) from the AQUA-MODIS satellite imagery. The results show that the relationship between wind speed and chlorophyll-a concentration has impact on other parameters where both parameters showed a strong correlation value. It was also showed on the relationship between sea surface temperature and chlorophyll-a.However, the relationship between salinity and chlorophyll-a concentration showed lowest effect among those parameters.Indonesian title: Dampak siklon tropis Amang terhadap variabilitas kecepatan angin, salinitas, suhu permukaan laut, dan hubungannya dengan klorofil-a di perairan laut Pulau Sangihe
