Abstract

Microalgae give an idea of the fertility of a body of water because the more microalgae in a body of water, the more fertile the water is. This research aims to determine the structure of the microalgae community in the Umbul water tourism area of Klaten Regency. This type of research is descriptive quantitative with a survey method. The data collection technique uses purposive sampling with hand-collection techniques. The data analysis technique uses the Shanon-Wiener diversity index (H'), species evenness index, dominance index, and species richness index as well as looking at physical and chemical parameters to determine water quality. The most common microalgae come from the Bacillariophceae and Cyanophyceae classes.The Shannon-Wiener diversity index for the three stations is in the stable category but the highest index value is at station III at 2.860 and the lowest index value at station I is 2.427. The highest species evenness index was at station I, namely 0.864, and the lowest index at station II was 0.764, so the species evenness index was stable. The highest Dominance Index at station II is 0.13 but is still close to 0 so the dominance index is low. The highest species richness index was at station III and the lowest at station II was 4.83. According to the results of the Umbul Nilo diversity index, Umbul Ponggok and Umbul Sigedang are included in the unpolluted category

Abstract

Selected as the National Fish Reserve (LIN), Maluku Province is known for its abundant marine resources and enormous fishery potential, supported by a capture fishery area of 658,294.69 km² which is the largest in Indonesia. Maluku has three Fishery Management Areas of the Republic of Indonesia (WPPNRI), namely WPPNRI-714, WPPNRI-715, and WPPNRI-718. However, based on production data for the capture fishery and aquaculture sectors in Maluku Province during the 2018-2022 period, these resource potentials have not been optimally utilized. Therefore, this research aims to analyze the ecological conditions and utilization of fishery resources in Maluku Province as a consideration for developing targeted policies and strategies for fishery resource utilization. This research uses a quantitative descriptive approach with data presented in narrative format, simple tables, graphs, and Multidimensional Scaling (MDS) analysis. Data collection was conducted from various sources over a 5-year period (2018-2022). Based on the analysis results, the status of ecological conditions and fishery resource utilization in Maluku Province is classified as less sustainable, indicated by Rapfish scores below 50. To improve the sustainability of fishery resource management in this region, strengthening of monitoring systems and community education about the importance of aquatic ecosystem conservation is needed.

Abstract

This research used the research object of payang fishing gear in the Pasie Nan Tigo area, Koto Tangah District, Padang City, which was carried out in May 2023. The method used is a descriptive method by making direct observations at the location of the trawl fishing gear in terms of the construction of the fishing gear, fishing area and type of fish caught. Based on the results of this research, the number of payang fishing gear found in Pasie Nan Tigo Village, Koto Tangah District, Padang City is 40 units. The method of operating the payang fishing gear is by circling schools of fish. The results caught by Payang fishing gear are Euthynnus sp, Rastrelliger sp., Katsuwonus pelamis, Stolephorus sp., Trichiurus sp., Leiognathus sp. and so on.

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

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.
