Building the Capacity and Knowledge about Coral Rehabilitation of Tour Guides in Lemukutan Island

The coral reef ecosystem is one of the marine tourism attractions on Lemukutan Island, West Kalimantan. However, currently, some locations are in a relatively degraded condition, which should be addressed. One solution to this problem is coral transplantation activities involving tour guides. As part of the effort to rehabilitate the coral reef habitats, the Aquatic Resource Management Department, Faculty of Agriculture, Nahdlatul Ulama University, West Kalimantan, conducted community development activities to increase the capacity and knowledge of tour guides regarding coral reef ecosystems and coral transplantation techniques. This training was attended by fifteen tour guides from the Lemukutan Guide Group and ARTUNA (Anak Remaja Teluk Cina) Group. The participants were previously trained under PT Pertamina (Persero) and Yayasan Jejak Pesisir Nusantara. This training was carried out in three stages: (i) materials presentation and discussions, (ii) direct practice on the field, and (iii) evaluation. The post-test results showed that the training had increased participants' understanding of coral reef ecosystems and coral transplantation techniques by 40,00% and 33,33%, respectively

Struktur Komunitas Ikan Pada Aliran Sungai Peniung Yang Melintasi Desa Ribang Kadeng Kecamatan Kalis Kabupaten Kapuas Hulu

The island of Kalimantan, known as Borneo to the international community, consists of three allied countries, namely Sarawak, Brunei Darussalam and Indonesia. In this part of the island there is an Indonesian territory whose northern part is directly adjacent to Sarawak and the Natuna Sea, the area is the Province of West Kalimantan. West Kalimantan province covers an area of 421,891 km2 and has hundreds of small and large rivers. The number of river flows in this province makes West Kalimantan province one of the provinces known as the area of a thousand rivers. The existence of the river is the soul of the people of West Kalimantan from the past until now. The Peniung River is one of the rivers located in Ribang Kadeng Village, Kalis District, Kapuas Hulu Regency. This river crosses the villages of Ribang kadeng and Na'sebintang (Nanga Sebintang) and flows into the Mandai River at the village of Na' Peniung. Information related to the diversity of fish species is necessary for the sustainable management of fishery resources. With this information, of course, the determination of policies and decision-making in the process of water resource management or use of hydrographic basins can be carried out correctly. However, the reality he is facing today is the lack of information on the diversity of freshwater fish, especially from the West Kalimantan region. This study managed to obtain 126 individuals of freshwater fish consisting of 10 families and 15 species. The diversity index obtained is moderate, index of Evenness is high and there are no dominant species

SEDIMENT CARBON STOCK OF WEST KALIMANTAN MANGROVE FORESTS

We investigate variation in sediment carbon stock at Mempawah and Bakau Besar in West Kalimantan by analyzing organic carbon content from sediment samples taken within 20 cm depth. Our results show that organic carbon stock of sediments in Bakau Besar is generally higher than in Mempawah that may be due to riverine input of organic carbon into the mangrove forests. The riverine input of organic carbon is influenced tides, in which we find that organic carbon loads are higher during high tide compared to low tide. In particular, we find high organic carbon contents at a station in Mempawah (Station 3; 6.46 ± 0.23 tons C/ha) and another station in Bakau Besar (Station 2; 14.93 ± 1.43 tons C/ha). These two stations have mangrove density of 13,519 individuals/ha and 9,928 individuals/ha, respectively. We conclude that high organic carbon is influenced by riverine input as well as a high density of mangrove and the dominant type of mangrove vegetation at the sites
