Abstract

Mangrove adalah vegetasi yang tumbuh di daerah pasang surut air laut maupun daerah muara. Salah satu muara yang terdapat di Kalimantan Barat ialah muara sungai Peniti dengan kondisi mangrove yang masih tergolong alami dan belum pernah dilakukan penanaman. Penelitian tentang analisis vegetasi mangrove dilakukan di muara sungai Peniti, Desa Sungai Burung Kabupaten Mempawah Provinsi Kalimantan Barat. Tujuan penelitian ini yaitu untuk mengetahui kondisi dan zonasi mangrove muara sungai Peniti. Lokasi penelitian ditentukan dengan metode purpossive sampling, adapun dalam pengukuran dan pengamatan vegetasi mangrove dengan menggunakan metode transek. Parameter yang diamati adalah komposisi jenis, kerapatan, kerapatan relatif, frekuensi, frekuensi relatif, dominansi dan indeks nilai penting mangrove. Hasil penelitian didapat 6 jenis mangrove yaitu A. marina, A. lanata, A. alba, E. agallocha, X. mekongensis, dan  N. Frutican. Nilai penting (INP) tertinggi untuk tingkat pohon ditemukan pada A. marina dengan nilai mencapai 210,12 %, sedangkan pada pancang dan semai yaitu A. lanata dengan nilai penting (INP) 200%.  Muara sungai Peniti tidak terbentuknya suatu zonasi mangrove.

Abstract

Mempawah Regency has abundant marine tourism potential, especially on Datuk, Setinjan, and Temajo Islands, which can be a driver of economic growth for the local community. However, the utilization of this potential is still constrained by the limited managerial capacity of the Jejak Nusa Tourism Awareness Group (Pokdarwis), the lack of supporting facilities, and the weak marketing strategy. The Partnership Community Service (PKM) Activity, funded by the Directorate of Research and Community Service, Directorate General of Research and Development, Ministry of Higher Education, Science, and Technology, aims to strengthen the capacity of Pokdarwis through training, mentoring, and the application of technology and innovation to realize sustainable ecotourism. The implementation method is carried out in a participatory manner through five stages, namely socialization, training, technology application, mentoring and evaluation, and program sustainability planning. Steps include preparing organizational work programs, providing business and financial management training, offering digital marketing assistance through blogs and social media, offering snorkeling facilities and underwater cameras, and facilitating cooperation with the village government and ship owners. The results of the activity showed a significant increase in the aspects of organizational management, finance, and digital marketing of Pokdarwis. Additionally, the presence of new tourism facilities encourages the growth of tourist interest, increases the community's income potential, and fosters social solidarity and environmental awareness. Thus, this program has succeeded in creating an ecotourism-based community empowerment model that supports economic welfare while maintaining the sustainability of marine ecosystems.

Abstract

Bostrychus cf. sinensis, a member of the family Eleotridae, was first identified in the Muara Telang region, Banyuasin, South Sumatra. Specimens collected from tidal channels were subsequently analyzed genetically using DNA barcoding with the Cytochrome Oxidase Subunit 1 (COI) gene. The molecular analysis revealed that the Muara Telang specimens shared 98.55% genetic similarity with Bostrychus sinensis from the Seom River, South Korea. According to genetic guidelines, a divergence greater than 3% may indicate a distinct species. The genetic divergence observed was 0.243, equivalent to 243 nucleotide variations out of 1,000 bases analyzed. Phylogenetic analysis showed that Bostrychus cf. sinensis from Muara Telang clustered within the same clade as Bostrychus sinensis but still exhibited genetic polymorphism at 8 distinct sites. Therefore, this specimen was designated as Bostrychus cf. sinensis. The COI gene sequence data for Bostrychus cf. sinensis from Muara Telang have been deposited in GenBank under accession MK777294.1.

Abstract

Muara Jeruju Village is an estuarine ecosystem influenced by the Kapuas River and anthropogenic activities of coastal communities in Kubu Raya Regency, Indonesia. These conditions generate considerable variability in mangrove growth dynamics. This study aims to quantify mangrove canopy cover using the Hemispherical Photography (HP) method as an indicator of ecosystem health. Data were collected from three stations representing the riverfront, middle, and hinterland zones, with a total of 15 hemispherical photographs (5 images per station) used as sampling units. Hemispherical images were processed using ImageJ software to estimate canopy cover percentages, which were subsequently classified according to the standards of the Geospatial Information Agency (BIG, 2014). The results indicate that canopy cover was 58.4 ± 1.85% in the riverfront zone, 72.8 ± 1.48% in the middle zone, and 65.1 ± 1.67% in the hinterland zone, indicating moderate to dense canopy categories. No sparse canopy class was identified across all stations. Overall, the mangrove ecosystem in Muara Jeruju Village can be categorized as being in moderate to dense condition based on canopy cover values (58.4–72.8%) according to the classification standard of the Geospatial Information Agency (BIG, 2014). However, the riverfront area experiences relatively higher environmental pressure due to sedimentation processes and water transportation activities.

Abstract

Kuala Secapah Village serves as a prominent hub for capture fisheries along the coast of West Kalimantan. Alongside premium catches, local fishermen frequently haul trash fish (ikan rucah), that remains economically underutilized. Applying innovative and sustainable processing approaches to these marine resources can significantly generate added value for the community. This community service program aims to educate and train coastal women on upgrading these underutilized catches into competitive food products. The program was delivered in participatory workshop divided into two sessions: an instructional lecture and a hands-on culinary production practice. The intervention yielded substantial progress, with participants' technical knowledge skyrocketing from 64% to 99.6% regarding standardized and proper fish-processing techniques. Ultimately, this initiative successfully fosters local economic resilience by converting underutilized marine waste into high-value commodities.
