Gen Z: Peduli Terhadap Ekosistem Mangrove di Kelurahan Lalowaru, Konawe selatan

Background: The problem of mangrove forest degradation in coastal areas is caused by various factors, including industrial activities, household activities, cultivation activities and land clearing for settlements. Previous research has stated that there needs to be concern from various parties so that mangrove forests in coastal areas are maintained. Until now, mangrove forest destruction, both natural and deliberate, is still quite high, making it a problem in most coastal areas. Situation Analysis: school students as the younger generation play an important role in disseminating knowledge about the importance of maintaining and preserving mangrove forests in coastal areas. Through this activity, it is hoped that a high level of love and concern for the environment can be created for school students in coastal areas. Approach Method: The approach stages carried out in this program consist of educating school students regarding the importance of maintaining mangrove forests in coastal areas. Results and Conclusions: When providing education to school students, they are first given an understanding of the importance of mangrove forests for the environment. After being given education and then practicing planting mangrove seeds directly, school students became enthusiastic about taking part in maintaining the mangrove ecosystem. Based on this, it can be concluded that education for the younger generation regarding the important function of mangrove forests needs to continue to be encouraged so that the younger generation is also involved in preserving coastal areas

Pelatihan Pengolahan Hasil Perikanan dan Kelautan Bagi Perempuan Pesisir di Kelurahan Lalowaru

Peran perempuan pesisir dalam tatanan sosial sudah mengalami perubahan. Saat ini, perempuan pesisir dianggap sebagai salah satu kontibutor dalam pemenuhan kebutuhan ekonomi rumah tangga dan memiliki kekuasaan dalam menentukan pembangunan suatu wilayah. Sehingga perempuan pesisir memiliki peran ganda, dalam rumah tangga dan lingkungan sosial. Keterlibatan perempuan pesisir di Kelurahan Lalowaru dalam membantu ekonomi rumah tangga belum berjalan optimal disebabkan karena minimnya pengetahuan dan keterampilan terkait dalam mengolah dan memanfaatkan sumberdaya yang dimiliki khususnya sumberdaya perikanan. Kegiatan pengabdian kepada masyarakat ini merupakan pendampingan bagi perempuan pesisir untuk membentuk kreatifivitas dalam memanfaatkan sumberdaya perikanan agar dapat menjadi karakter mandiri dan memiliki jiwa wirausaha. Dengan adanya kegiatan pengabdian ini, diharapkan mampu membantu ekonomi rumah tangga. Sasaran pelaksanaan pengabdian ini adalah ibu-ibu rumah tangga di Kelurahan Lalowaru. Program kegiatan dilaksanakan melalui penyuluhan dan pelatihan pengolahan pembuatan otak-otak ikan dan stik mangrove. Hasil dari kegiatan pegabdian menunjukkan peserta pelatihan aktif dalam berdiskusi terkait dengan pengolahan dan strategi pemasaran serta melakukan demo masak sesuai dengan instruksi tim pengabdian. Kegiatan ini diharapkan dapat membentuk karaktek mandiri dan jiwa wirausaha sehingga dapat membantu ekonomi rumah tangga di Kelurahan Lalowaru

Mapping the change of coral reefs using remote sensing and in situ measurements: a case study in Pangkajene and Kepulauan Regency, Spermonde Archipelago, Indonesia

As elsewhere in Indonesia, local inhabitants in the Pangkajene and Kepulauan (PANGKEP) Regency, Spermonde Archipelago area and along the south-west coast of Sulawesi traditionally regard the coral reefs as their livelihood source. Since human activities as well as natural disturbances pose major threats to the coral reefs, these livelihoods may also be at risk. Currently, no comprehensive information on the status and condition of coral reefs in this area is available for this resource management. We determined the changes of coral reef habitat over a period of 20 years from 1994 to 2014 using a satellite Landsat multi-temporal image substantiated with in situ measurement data collected in 2014. The spectral value of coral reefs was extracted from multi-temporal Landsat imagery data, while the diffuse attenuation coefficient of water was obtained by using statistical analysis between the ratio of live coral cover and the spectral value of the visible bands. By using the unsupervised classification integrated with the data ground truth, it is stated that there has been a decline in live coral cover over a period of 20 years from 7716 ha in 1994 to 4236 ha in 2014, with a degradation rate of 174 ha/year. Based on the results, the ratio of the coral cover in the coral reef transects varied from the average of 24% for live corals to 96% for coral rubbles, implying the degraded status of coral reefs in the study area

Assessing economic values of coral reefs in the Pangkajene and Kepulauan Regency, Spermonde Archipelago, Indonesia

Coral reef ecosystems possess tangible and intangible economic benefits to human society that are still underestimated and not fully understood. This study aims: to determine 1) economic benefits and economic losses due to coral reef damage, 2) compensation values as replacement costs for damaged coral reefs as well as references to sustainable coral reef management. Based on the calculation, the TEV of coral reef ecosystems was estimated to be USD 11.96 billion or 2.82 million USD/ha. The economic losses due to coral reef destruction over the 20-year period from 1994 to 2014 were USD 1 billion or 50.18 million USD/yr. We anticipate that the economic loss of coral reefs will continue to rise due to the intensification of destructive fishing practices. Therefore, an effective management policy should be established to prevent further destruction of coral reefs in this area in the future. This study suggests that tangible procedures for compensation for coral damage and law enforcement for destroyers are required to be implemented to reduce the economic losses of coral reefs, and the economic values estimated in this study can be a quantitative reference for various stakeholders to build a concensus for designing coral reef recovery programs in the future

Assessment of coral reef ecosystem status in the Pangkajene and Kepulauan Regency, Spermonde Archipelago, Indonesia, using the rapid appraisal for fisheries and the analytic hierarchy process

Coral reefs in the world's tropical and subtropical oceans have long been under considerable threat. The aims of this study were to identify the types of threat affecting coral reefs, to conduct a sensitivity analysis to assess the sustainability of coral reef ecosystems, and to suggest alternative strategies that should be deployed to improve the status of coral reef ecosystems in the Pangkajene and Kepulauan (PANGKEP) Regency, Spermonde Archipelago, Indonesia. The data obtained were analyzed using the rapid appraisal technique for fisheries (RAPFISH) and the analytic hierarchy process (AHP). The RAPFISH analysis identified 41 types of threat to the status of coral reef ecosystems, based on five indices: economic (51.92), social (47.33), technological (47.26), legal and institutional (45.60), and ecological (37.65). The averaged cumulative index of coral reef ecosystem sustainability was 45.95, within a threshold denoting a "less sustainable" status. The AHP analysis suggested that several alternative strategies are needed to improve the status of coral reef ecosystems, with greater prioritization of socialization, campaigns, and education, followed by law enforcement, selectivity in the use of fishing gear, rehabilitation of coral reef ecosystems, and restocking of fish in coral reefs. The findings of this study can be used as points of reference when local policymakers begin to formulate appropriate strategies for the sustainable use of coral reef ecosystems
