Abstract

Seagrass restoration practice of transplanting grown seagrass from a donor to the planting site is discovered to disrupt the existing ecosystems. An alternative method includesthe use of seedlings, which requires a protected germination environment to survive. At the initial stage, the seedlings need adequate space for growth and expansion of root systems. However, cultivating seagrass seedlings in aquariums is challenging due to limited space. Therefore, this study aimed to investigate the growth and development of aquarium-cultured seagrass seedlings and evaluate the impact of different spacing on growth. Seedlings were cultivated in the laboratory under 2 treatments, each lasting 3 months. Enhalus acoroides seedlings collected from Dompak Island, Tanjungpinang, were used with varying planting distances for each treatment. The results showed that Treatment A (4 cm spacing) had a lower survival rate (66.73%) compared to TreatmentB (1.5 cm spacing) (97.78%) due to a fungus outbreak.However, Treatment B had slower growth than A, suggesting potential problems with water quality and increased competition for resources in denser plantings. In this study, the significance of planting spacing was outlined and a statistically significant difference was discovered in seagrass growth between various treatments (P0.05). A rapid growth rate of 2.08-3.02 mm/day was observed in leafs, which exceeded the value observed in previous investigations conducted under similar conditions and species. It was important to acknowledge that leaf length was also 17.5-21.6 cm, exceeding the values observed in another experiment using lab-cultured E. acoroides. Root lengths were comparatively shorter (7.6-8.2 cm), which signified the dynamic nature of seagrass development. In conclusion, addressing environmental conditions and optimizing planting spacing, was essential for sustainable growth.Keywords:EnhalusGrowthSeagrassSeedlingsSpacing

Abstract

Waste, particularly plastic, poses a serious threat to coastal ecosystems in the Anambas Islands, Riau Islands Province. This community service program collaborated with LKKPN Pekabaru and Yayasan Jaga Mangkai aimed to enhance environmental literacy, raise awareness on waste management, and introduce the potential of mangrove waste (Bruguiera gymnorhiza) as raw material for environmentally friendly bioplastic. The methods included educational sessions, interactive discussions, coastal clean-up activities, and evaluation using pre-test and post-test questionnaires. The results revealed that from 407.1 kg, 69% of the collected waste consisted of non-plastic categories. Laboratory tests on mangrove waste indicated the presence of active compounds with potential for bioplastic production. Questionnaire evaluation showed a significant improvement in community understanding, with average scores exceeding 50% in aspects of waste knowledge, bioplastic innovation, and attitudes toward environmental management. In conclusion, the program effectively increased ecological awareness and highlighted the potential for local innovation based on coastal resources. Nevertheless, follow-up programs are necessary to ensure that improved knowledge is transformed into sustainable daily practices in waste management.

Abstract

Coral fish groups have a very strong dependence on coral reef ecosystems. Nusa Manggala Expedition was carried out for twenty days to explore basic data on the diversity of species of coral reef fish in the Liki, Bepondi, and Miossu Islands. Assessment of coral fish assemblages using Underwater Visual Census (UVC). Four hundred and thirty-two species of fifty families of reef fishes found during the 2nd session the Nusa Manggala expedition in Liki, Bepondi, and Miossu islands, northern Papua. Four species (Mobula tarapacana, M. alfredi, Oxymonacanthus longirostris, Bolbometopon muricatum, and Plectropomus areolatus) and one species (Cheilinus undulatus) categorized of IUCN as Vulnerable (VU) and Endangered (EN), respectively, were recorded in this study. There is unique pattern of reef fishes’ composition in small outer islands location in pristine location that shows Pomacentridae and Labridae were almost in the same number as Gobiidae, Apogonidae, Serranidae, Chaetodontidae, and Acanthuridae. In addition, the results showed that the Liki and Miossu islands and Bepondi Island included at the Coral Fish Diversity Index (CFDI) as an extraordinary and excellent category of marine fish, respectively. The results of the expedition showed that the Liki Islands and Miossu Island had an extraordinary category of marine fish, and Bepondi Island had an excellent category of sea fish. The culture of local people in Papua called "Sasi" prove to provide full protection to the ecosystem and have a positive impact on high diversity of reef fishes.

Abstract

Epifit adalah organisme yang menempel pada permukaan tumbuhan seperti pada daun lamun. Keberadaan epifit pada daun lamun dalam kondisi yang berlebih dapat mengakibatkan penurunan produktivitas pada lamun. Terdapat dua jenis lamun yang memiliki tingkat kehadiran yang cukup tinggi di perairan yaitu Enhalus acoroides  dan Thalassia hemprichii. Tujuan dari penelitian ini ialah untuk mengidentifikasi jenis epifit yang menempel dan menghitung kelimpahan epifit pada lamun Enhalus acoroides dan Thalassia hemprichii di Pesisir Timur Pulau Bintan. Terdapat 3 stasiun pengamatan, yaitu meliputi: Teluk Bakau. Malang Rapat, dan Berakit. Penentuan lokasi pengamatan berdasarkan Purposive Sampling. Metode sampling menggunakan transek kuadrat 50x50 cm dan diletakkan pada titik 0 m, 50 m, dan 100 m pada line transek yang tegak lurus dengan garis pantai. Hasil penelitian menunjukkan bahwa komposisi epifit pada lamun Enhalus acoroides dan Thalassia hemprichii terdiri dari 5 kelas yaitu Bacillariophyceae, Cyanophyceae, Dinophyceae, Chlorophyceae, dan Conjugatophyceae. Kelimpahan epifit pada lamun Enhalus acoroides pada ketiga lokasi penelitian berkisar 4912,74 – 7517,25 ind/cm2. Kelimpahan epifit pada lamun Thalassia hemprichii di ketiga lokasi penelitian berkisar 6128,29 – 7600,37 ind/cm2. Berdasarkan hasil analisis komponen utama  menunjukkan bahwa kelimpahan epifit memiliki keterkaitan dengan nirat dan fosfat.
