Abstract

Water is a vital need for every life, so if there is no water there will certainly be no life.  This research aims to determine the pattern of springs, diversity and similarity of types around the springs. The research method uses surveys and sampling techniques. Research results of Meja Mountain Natural Tourism Park (MMNTP) from 9 springs have 7 different spring patterns. The largest water discharge in the spring pattern that comes out between the rocks, while the smallest water comes out of seepage of soil pores. The largest water discharge is located in Manggoapi with coordinates -0.847744, 134.069008. While the smallest water discharge comes from springs that emerge from the ground located in Brawijaya with coordinates -0.854717, 134.075233.   The woody vegetation type diversity index has a high value which reflects the diversity of types in the MMNTP.  Meanwhile, the similarity index is higher than the difference, indicating that woody vegetation has similarities between the observation plots. Establish from seedlings to dominant trees including Palaquium amboinensis, Artocarpus altilis, Lansium domesticum, Pometia coriacea, Pometia pinnata, and Koordersiodendron pinnatum. The six types are thought to have suitable habitats, need lots of water and have related relationships.

Abstract

Mangrove forests are tropical and subtropical coastal vegetation communities that can grow and develop in muddy coastal intertidal areas. This study aimed to identify and analyze the structure and canopy cover of mangrove ecosystems in SFV (Smart Fisheries Village). The research was conducted using a survey method. The observation station was determined by purposive sampling method. Data analysis was done using descriptive statistical methods. Mangroves in SFV (Smart Fisheries Village) West Pasaman are Avicennia marina, Rhizophora apiculata, Sonneratia alba, and Aegiceras corniculatum. The highest density of mangrove trees, saplings, and seedlings are 500 Ind/ha, 3866.67 Ind/ha, and 66666.67 Ind/ha with mangrove species Rhizophora apiculata. The highest frequency of tree category species with Rhizophora apiculata species is at stations 1, 2, 3 and Soneratia alba at stations 1 and 3. The highest frequency of seedling category species is Rhizophora apiculata at all three stations, Soneratia alba at station 3, and Avicennia marina at station 2. The highest frequency of seedling category species at all three stations is Rhizophora apiculata and Soneratia alba at station 3. The highest mangrove species cover is Rhizophora apiculata at stations 1 and 2 with a value of 68.04% (station 1), 69. 81%, (Station 2), and Soneratia alba 50, 35%, (Station 3) The index of important value (INP) of mangroves at the level of trees, saplings, and seedlings is highest in the species Rhizophora apiculata successively at all stations The value of diversity index (H') is categorized as low, while the dominance index is categorized as moderate. The percentage of mangrove canopy cover is classified as mild.

Abstract

Fish feed is known to account for 60-70% of total aquaculture costs, posing a significant challenge to farmers. To address the issue, this study explored the effectiveness of periodic starvation in improving feed efficiency and growth performance of climbing perch while reducing the cost of purchasing feed. The method used was a completely randomized design (CRD) analyzed using ANOVA. Four treatments were applied with three replicates each. The treatments consisted of P0 (no fasting), P1 (one day of fasting followed by one day of feeding), P2 (one day of fasting and two days of feeding), and P3 (one day of fasting and three days of feeding). The parameters observed included feed efficiency, growth in length and absolute weight, and fish survival rates. The results showed that periodic starvation significantly impacted the absolute body weight growth and feed efficiency (P<0.05). However, no effect was observed on the survival rates and absolute length growth. Among the treatments, P1 showed the best results, with feed efficiency of 21.87%, length growth of 0.23 cm, weight growth of 0.22 g, and survival rate of 100%. In conclusion, this study found that periodic starvation combined with feeding could significantly improve fish feed use efficiency and save fish farmers' costs.

Abstract

Ngurbloat Beach, located in the Kei Islands, Maluku Province, has a varied coastal ecosystem, including benthic habitats that play an important role in ecological balance and sustainability of marine resources. This study aims to map the spatial distribution of benthic habitats including substrates in the waters of Ngurbloat Beach by utilizing Allen Coral Atlas data. The analysis was conducted through classification of high-resolution satellite images using remote sensing and geographic information system (GIS) methods. The results showed that the total mapped area was 183 ha. Benthic habitats in this area are dominated by coral reefs (18.99%), seagrasses (0.85%), microalgae (2.93%) and sand substrates (16.42%), rocks (39.44%) and dead corals (22.7%). Oceanographic factors and anthropogenic activities in the waters of Ngurbloat Beach affect the distribution of benthic habitats, especially coral reefs that have suffered serious damage and need to be rehabilitated. The utilization of Allen Coral Atlas data proved effective in providing accurate spatial data for benthic ecosystem mapping, which can support conservation efforts and sustainable management of coastal resources.

Abstract

Mangroves are coastal ecosystems, especially in tropical areas including Tomini Bay, Gorontalo Province. Mangrove ecosystems not only function as coastal abrasion barriers, natural protection from ocean waves, but also as plants that are beneficial to human life, especially for coastal communities. . This study aimed to identify and analyze the structure of mangrove communities on the coast of Tomini Bay, Boalemo Regency, Gorontalo Province. Data collection was carried out using the line transect method at four observation stations for the seedling and sapling categories., then analyzed to determine the absolute density, absolute frequency, and dominance of species. Mangroves found in Tomini Bay, Boalemo Regency from the four stations consist of A. marina, B. gymnorhiza, B. parviflora, C. decandra, C. tagal, R. apiculata, R. mucronata, R. stylosa, S. alba, S. caseolaris, X. moluccensis. In the seedling category, the C. tagal mangrove species at station 2 (Dulangeya Village) showed the highest value in Boalemo Regency, with an absolute density of 56 ind/m², an absolute frequency of 0.48, and a relative dominance of 87.5%. On the other hand, the B. gymnorhiza species recorded the lowest value compared to all observation stations in Boalemo Regency, with an absolute density of only 1 ind/m², an absolute frequency of 0.05, and a relative dominance of 1.56%. The C. tagal mangrove sapling category at station 2 (Dulangeya Village) had the highest absolute density, absolute frequency, and relative dominance in Boalemo Regency, at 8.36 ind/m2 and 0.71 and 73.85, respectively. R. apiculata had the lowest density of all stations in Boalemo Regency, at 0.04 ind/m2 and 0.05 and 0.35, respectively
