Pojok Literasi Sebagai Upaya Meningkatkan Minat Baca Di Pulau Panjang, Lepar Pongok, Kabupaten Bangka Selatan

Students Association of Himakuatik was implemented The Bina Desa program in Panjang Island, Penutuk Village, Lepar Pongok District, South Bangka Regency. Panjang Island is one of the isolated islands in the Bangka Belitung Islands which has a low literacy culture, especially among children. One of the causes of the low level of literacy skills of elementary school students in Panjang Island is due to the small collection of fiction and non-fiction reading books at school and at home. The purpose of the work program to create a literacy corner in Pulau Panjang is to provide reading facilities and form reading habits for Pulau Panjang children. The implementation of activities goes through several stages, namely preparation, implementation and evaluation. The results of the service obtained are the availability of literacy facilities in the form of a literacy corner and forming reading habits for children in Long Island Hamlet.

Data Mining Earthquake Prediction with Multivariate Adaptive Regression Splines and Peak Ground Acceleration

Earthquake research has not yielded promising results because earthquakes have uncertain data parameters, and one of the methods to overcome the problem of uncertain parameters is the nonparametric method, namely Multivariate Adaptive Regression Splines (MARS). Sumbawa Island is part of the territory of Indonesia and is in the position of three active earth plates, so Sumbawa is prone to earthquake hazards. Therefore, this research is important to do. This study aimed to analyze earthquake hazard prediction on the island of Sumbawa by using the nonparametric MARS and Peak Ground Acceleration (PGA) methods to determine the risk of earthquake hazards. The method used in this study was MARS, which has two completed stages: Forward Stepwise and Backward Stepwise. The results of this study were based on testing and parameter analysis obtained a Mathematical model with 11 basis functions (BF) that contribute to the response variable, namely (BF) 1,2,3,4,5,7,9,11, and the basis functions do not contribute 6, 8, and 10. The predictor variables with the greatest influence were 100% Epicenter Distance and 73.8% Magnitude. The conclusion of this study is based on the highest PGA values in the areas most prone to earthquake hazards in Sumbawa, namely Mapin Kebak, Mapin Rea, Pulau Panjang, and Pulau Saringi.

Keandalan Jaringan Distribusi Di Pulau Panjang Dengan Pembangkit Listrik Tenaga Diesel

By examining the issue of the electrical power distribution system's dependability, particularly on the outer islands, in this case Pulau Panjang, it can be seen that the usage of electrical energy in Indonesia is still predominantly controlled by steam power plants. It is discovered that the Diesel Power Plant is this location's primary source of electrical energy. Since 2019, the use of PLTD has been running continuously here, with four primary engines operating efficiently. However, each day, only two machines run alternately for 12 hours, raising a reliability concern that has to be looked into. The SAIDI and SAIFI values obtained using these approaches are extremely high (403,645 for SAIDI and 16 for SAIFI), Then, it was claimed that an index comparison based on SPLN 68-2: 1986, IEEE, and WCS as of January 2022 to June 2022 was erroneous. Thus, the installation of PLTS in the Long Island region is required as a substitute for electrical energy. In order to achieve optimal performance, the diesel working time limit is decreased using the PLTS technology

Sea Transportation Services for Panjang Island

The problem of sea transportation on Pulau Panjang, Batam City, is that it is inadequate for marine transportation owing to the lack of safety buoys, excessive passenger loads, and the absence of passenger safety insurance. The purpose of this study is to assess the marine transportation services in Pulau Panjang and their adherence to the framework of governance, and to determine the characteristics of good governance in sea transportation services. This type of qualitative research is descriptive, and anlaysed using qualitative techniques (data reduction analysis techniques, data presentation, and drawing conclusions (verification). There were nine research informants and one person as the key informant. The theory used in this study was the theory of good governance, namely the public government and the private sector. The results of this study indicate that sea transportation services on Panjang Island needs improving and will benefit from the involvement of three key stakeholders: the government (in the form of the Department of Transportation and the Education Office); the owner of the ferries; and the people of Panjang Island as passengers. When viewed from the principle of good governance, the responsiveness of the government already exists but is not sustainable and there is no supervision from the government and community participation is still very low so that their aspirations are not conveyed to the government and the means of transportation owned by the private sector are also not effective and efficient for used as a means of public transportation.

Microplastics abundance in gills and gastrointestinal tract of Epinephelus fuscoguttatus-lanceolatus at the Coastal of Pulau Panjang, Serang, Banten

Microplastics are plastic particles in the size of <5 mm. Bioaccumulation of microplastics in the marine biotas, including fishes, occurs through the food chain. Microplastics enter the fish body through their gills and mouth. Contamination of microplastics inside the fish body can cause several effects, such as increasing toxicity effect, and growth inhibition. This research analyzed the form and amount of the microplastics found in each gill and gastrointestinal tract of the fish samples. A total of 15 samples of cantang grouper were taken from the floating net cage near Kampung Peres, Pulau Panjang. Samples were transported to the laboratory using an icebox. The gill and gastrointestinal tract of samples are isolated from their body, then destructed with HNO3 65% for 24 hours. After 24 hours, the samples were mixed with the concentrated NaCl solution with a ratio of 1:4. Microplastics form and amount are observed under the light microscope with three times repetition. The results show that the microplastics found in the gill and gastrointestinal tract of cantang groupers are mostly found in the form of fragments. The microplastics abundance in gills was 51893,33 ± 2594,67 particles/individual, and in the gastrointestinal tracts was 83926,67 ± 4196,33 particles/individual.

Selection of sustainable seaweed and grouper aquaculture development strategy: a case of Pulau Panjang, Serang Regency Banten Province

Due to their high-income contribution, seaweed and grouper aquacultures are important activities in Pulau Panjang community. Determining alternative strategies in developing sustainable aquaculture for seaweed and grouper and their priority factors from theses aquaculture activities are done using TOPSIS and AHP analysis. It was found that the development strategy that must be taken is the option to maintain aquaculture activities, while, environment factor is the highest priority to maintain seaweed and grouper aquaculture in Pulau Panjang. Then three priorities are obtained from environment factor. The first is to maintain the water quality by the growth requirements of seaweed and grouper by encouraging the formation of “Environmental Community Awareness” that involved the active participation of the community to maintain quality and carrying capacity of the environment. Second is to use of natural or artificial coastal protectors (soft structure). The third priority strategy is integration and real implementation of heavy metal pollution control between government, industry sector and society.

Genetic diversity and phylogeny of the Christmas Island flying fox (Pteropus melanotus natalis)

The Christmas Island flying fox (Pteropus melanotus natalis) is thought to be declining to critically low levels. Mitochondrial sequences of the cytochrome oxidase 1 (CO1) and cytochrome b (Cytb) genes and the D-loop were generated from 28 animals and used with maximum likelihood, Bayesian inference, and maximum parsimony methods to determine its relationship to other Pteropus species. In all analyses, P. m. natalis mapped to a large clade containing Pacific Ocean island and Australian Pteropus species. Analysis using the large numbers of available Cytb sequences for Pteropus showed that P. m. natalis maps to a subclade that contains P. hypomelanus sequences from bats originating from Pulau Panjang, an island off the northeast coast of Java. P. hypomelanus was found to be polyphyletic, mapping to 3 separate subclades. These 3 genetically and geographically defined populations are likely to represent 3 separate species. Eighteen D-loop haplotypes were identified, suggesting that P. m. natalis maintains a degree of genetic diversity similar to other insular flying fox species.

Results: The results of identification from 6 sponges were Phakettia euctimenna, Gelliodes fibolatus, Lamellodysidea herbacea, Clathria reindwardtii and Callyspongia sp, while antibacterial assay for the secondary metabolite actinomycetes associated sponges showed negative results. Conclusion: Secondary metabolite actinomycetes associated sponges from Pulau Panjang were not found to have antibacterial activity against S. aureus MRSA.

KAJIAN HUBUNGAN FOSFAT AIR DAN FOSFAT SEDIMEN TERHADAP PERTUMBUHAN LAMUN Thalassia hemprichii DI PERAIRAN TELUK AWUR DAN PULAU PANJANG JEPARA

Seagrass growth is limited by the supply of nutrients such as nitrogen and phosphate particulates that serve as energy for photosynthesis. The magnitude of the role of phosphate in the metabolism and growth of seagrass Thalassia hemprichii important to serve as a study to determine the relationship of nutrients to the growing rate of seagrass in Teluk Awur and Pulau Panjang Jepara. The purpose of this study was to determine the concentration of phosphate in the water and sediment in the waters of the Teluk Awur and Pulau Panjang and its relation to seagrass leaf growth rate of T. hemprichii. The study was conducted in April - July 2012 includes literature studies, site surveys, field data collection and analysis of samples. Analysis of the relationship phosphate concentration on the rate of growth of seagrass T. hemprichii using bivariate correlation analysis. The results showed that the average growth rate - the average seagrass highest type T. hemprichii found in Teluk Awur on 8 week (0.81 cm/day). Meanwhile, the lowest growth rate found in Teluk Awur at week 2 (0.14 cm/day). The content of phosphate concentration of water in the Teluk Awur ranged from 0.009 to 0.028 mg/L and in Pulau Panjang ranged from 0.012 to 0.025 mg/L. The concentration of phosphate sediments in the Teluk Awur ranged from 20.870 to 23.250 mg/kg and Pulau Panjang 25.650 to 27.190 mg/kg. Relations water phosphate concentration and phosphate sediments to seagrass leaf growth in Teluk Awur are not considered closely related ,instead phosphate water to the growing rate of seagrass in Pulau Panjang is low and phosphate sediments to seagrass growth as very closely.

STRATEGI ADAPTASI NELAYAN TERHADAP PERUBAHAN EKOLOGIS

There is ambiguity on conducting sustainable development in coastal area. In fact, there are still virgin coastal areas, while some coastal areas have been exploited intensively across their carrying capacities. Beside environmental conservation efforts, some adaptation strategies for the fishermen to free the changes coastal areas are needed. The result of case study in Panjang Island, South Kalimantan shows that ecological changes were caused by land degradation of mangrove’s areas. The development of mangrove’s areas are the coal ports and shrimp ponds have changed their function as natural resource, especially as natural resource of community’s livelihood. Pulau Panjang is only approximately 5 Ha, but there are at least 7 coal ports arround its coastal area. Consequently, the fishermen have lost their fish stock and their livelihood. In response to the ecological changes, adaptation may play important role. The community should be able to respond the direct and indirect effects of the changes. In deed, the fishermen in Panjang Island have their own adaptation strategies that devide into economic strategy, political strategy and social strategy. The fishermen try to colaborate their sources of income, take the benefit of social connection and exploitate their other natural resource.
