Abstract

Seagrass ecotourism is a tourism activity based on seagrass ecosystem as an educational tour by seeing the ecology of seagrass meadows and associated biota. Conservation awareness and improving community welfare, seagrass ecotourism is a nature-based tourism strategy with the aim of environmental conservation and containing aspects of community education and culture. Determining the sustainability status of seagrass ecosystem management is very important as a basis for future policy planning. The sustainability of seagrass ecosystems needs to be protected, so a policy strategy is applied in sustainable seagrass ecosystem management. The objectives of the study are: 1) determining the sustainability status of ecotourism-based seagrass ecosystem management based on ecological, economic and social dimensions, 2) determining the policy strategy for ecotourism-based seagrass ecosystem management. The results of the study obtained the sustainability status of ecotourism-based seagrass ecosystem management based on ecological dimensions is quite sustainable while the economic and social dimensions are less sustainable. The strategy for sustainable policy for managing seagrass ecosystems based on ecotourism on Maitara Island, Tidore Islands, namely education about seagrass ecosystems for the community, managing seagrass ecosystems based on ecotourism, increasing seagrass rehabilitation programs, maximum limits for carrying capacity of seagrass ecotourism, training for developing managers of seagrass ecotourism based on ecosystems, increasing job opportunities and business opportunities, legality of seagrass areas as conservation areas in the tourism utilization zone category and strengthening laws and institutions.Keywords:analysismultidimensionalsmall islandsustainabilitytourism

Abstract

The Halmahera Walking Shark (Hemiscyllium halmahera) is an endemic species in the Halmahera Sea. Information related to the environment in general has not been described in a complex manner. The environment is the main factor to support the life of biota. Environmental characteristics are a determining factor in the sustainability of biota. The study aims to provide information related to the physical environment of the habitat of the H. halmahera species. Primary data collection was carried out directly (in situ). Current data was taken using the Lagrange method using a currents drogue. Tides using tidal palms and observed for 24 hours. Secondary data was taken from Marine Copernicus and the Geospatial Information Agency (BIG). All data were tabulated and analyzed by Ocean Data View (ODV) software. The results of the study found that the surface current velocity was found to be in the fast current category. Current speed descriptively provides information on the life of H. halmahera. Primary data shows that the direction of the surface current moves to the east and north. Secondary data in vertical distribution shows weak zonal and meridional current shifts. The tidal pattern was found to be two high and low tides (semidiurnal). The distribution of surface temperature was found to be around 30-32oC. The vertical temperature profile found three layers, namely 1-13m (30oC), 65m (25oC) and 71m (20oC). The chemical environment showed all normal variables. The physical and chemical environmental conditions support H. halmahera to inhabit the sea area of Morotai Island. The environmental description has provided a brief understanding of how the ecological role of the H. halmahera species. Management and sustainability of the environment in the future due to climate change can be done with information on habitat characteristics.Keywords:coral triangleHalmaheranicheNorth Malukutropical

Abstract

NPK is a type of fertilizer that plays a role in increasing growth and survival in plants such as seaweed. This study aims to determine the effect of different NPK fertilizer doses on the growth rate of seaweed (Caulerpa racemosa), and to determine which NPK fertilizer dosage has the best effect on the growth rate of C. racemosa. Research begins with collecting samples of seaweed in coastal waters. Ternate Island District Kastela, and the cultivation process is carried out on Jalan Jan, Tabona Village, South Ternate City. The time of the research was two months from August to October, 2020. This study used 12 units of cool box in the form of cork with a size of 90 x 30 cm, which is used as a container for maintaining of C. racemosa. In each treatment using a seed weight of 50 grams. The NPK fertilizer dosage treatment tested was 4 doses, with 3 replications, namely: treatment A: 40 ml NPK fertilizer; B: 60 ml NPK fertilizer; C: 80 ml NPK fertilizer; D: 0 ml NPK fertilizer (control). Research containers using random placement. The design used was a completely randomized design (CRD), using analysis of variance (ANOVA). The results obtained showed that NPK fertilizer with different doses the effect is not significantly different on the growth rate of C. racemosa with the highest average growth rate in treatment C amounting to 8.725%, followed by treatment B of 8.178%, treatment A of 7.761%, and the lowest was treatment D of 6.519%.Keywords:NPKSeaweedCaulerpa racemosaGrowth rate

Abstract

Dialog Interaktif sebagai wadah komunikasi antara pemerintah Maluku Utara dengan masyarakat dalam rangka penyusunan RPJMD 2025-2029 berfungsi sebagai sarana efektif untuk menyerap aspirasi publik serta menyampaikan arah kebijakan pembangunan daerah. Proses dialog berlangsung secara langsung dan interaktif, memungkinkan masyarakat berpartisipasi aktif menyampaikan kebutuhan, harapan, dan kritik secara terbuka kepada pemangku kebijakan. Fokus utama pembahasan tertuju pada isu strategis seperti pengembangan infrastruktur, peningkatan kualitas pelayanan publik, pemberdayaan ekonomi lokal, serta pengelolaan sumber daya alam secara berkelanjutan. Interaksi dua arah yang berlangsung membantu mengurangi kesenjangan informasi antara pemerintah dan masyarakat sekaligus memperkuat transparansi serta akuntabilitas penyusunan RPJMD. Narasumber dari berbagai kalangan, termasuk pejabat pemerintah, akademisi, dan tokoh masyarakat, menyampaikan perspektif berbasis pengalaman dan data relevan, sehingga dialog menjadi lebih kaya dan aplikatif. Partisipasi luas dari berbagai lapisan masyarakat menandakan tingginya minat untuk terlibat dalam proses pembangunan daerah secara langsung. Hasil dialog ini memberikan masukan yang konkret dan konstruktif bagi pemerintah daerah guna merumuskan kebijakan pembangunan yang inklusif dan responsif terhadap kebutuhan masyarakat. Dialog Interaktif ini tidak hanya meningkatkan pemahaman publik tentang prioritas pembangunan, tetapi juga mendorong terciptanya hubungan yang harmonis antara pemerintah dan warga. Model komunikasi ini layak dijadikan contoh bagi daerah lain yang ingin memperkuat mekanisme partisipasi publik serta memastikan pembangunan yang berkelanjutan dan berbasis aspirasi nyata masyarakat.
