Abstract

Mangrove forests provide essential ecological and economic services; however, increasing human activities and natural disturbances have led to widespread degradation, highlighting the need for effective rehabilitation efforts. This study evaluated the success of mangrove rehabilitation in the concession area of PT Kandelia Alam, Kubu Raya Regency, Indonesia, using indicators of survival rate, plant height, leaf number, and environmental conditions. Data were collected under three site conditions (flooded, flowing-water, and unflooded areas) across two observation stations, each consisting of three measurement plots. Each plot measured 20 × 50 m and contained a 20 × 20 m subplot representing 100 individual plants, with observations conducted up to T₀ + 9. The results indicated that rehabilitation success at Stations I and II was moderate, with survival rates of 74.33% and 72.17%, respectively. Average plant heights were 50.60 cm at Station I and 53.66 cm at Station II, with an average of five leaves per individual at both stations. The Rhizophora  mucronata and Bruguiera gymnorrhiza species exhibited better adaptability in flowing-water and unflooded areas, whereas the Rhizophora apiculata species showed lower survival rates, particularly under flooded conditions. Environmental parameters at both stations were generally within suitable ranges for mangrove growth, including salinity of approximately 22 ppt, water temperature of 28°C, water pH of 7, soil temperature of 30–31°C, soil pH of 5.5, and substrates dominated by silty clay and silt. These findings suggest that while survival rates indicate moderate rehabilitation success, vegetative growth remains suboptimal, emphasizing the importance of site–species matching, hydrological suitability, and early-stage maintenance to enhance long-term mangrove rehabilitation outcomes.

Abstract

Tanah ultisol yang mendominasi wilayah Kalimantan Barat (64,83%) menghadapi kendala kesuburan utama berupa pH sangat masam dan kandungan kalium yang tersedia rendah. Penelitian ini bertujuan mengevaluasi efektivitas amelioran Turbinaria sp. segar dan fermentasi dalam meningkatkan kandungan kalium dan memperbaiki pH tanah ultisol. Rancangan Acak Lengkap diterapkan dengan tiga perlakuan: kontrol tanpa amelioran (T₀), aplikasi 100 g/kg Turbinaria sp. segar (T₁), dan aplikasi 100 mL/kg Turbinaria sp. fermentasi menggunakan EM4 selama tujuh hari (T₂), masing-masing lima ulangan. Analisis kalium menggunakan ICP-OES Agilent 5900 pada panjang gelombang 767 nm dan pH diukur dengan pH meter digital secara in situ pada hari ke-3, 7, 10, dan 14. Hasil menunjukkan perlakuan fermentasi (T₂) memberikan kandungan kalium tertinggi sebesar 0,33 cmol/kg pada hari ke-7, meningkat 65% dibandingkan kontrol (0,20 cmol/kg), sedangkan perlakuan segar (T₁) meningkat 50% (0,30 cmol/kg). pH tanah perlakuan segar mencapai nilai tertinggi 7,00 pada hari ke-10, sementara perlakuan fermentasi dan kontrol mengalami fluktuasi lebih moderat. Uji ANOVA menunjukkan pengaruh sangat nyata aplikasi amelioran terhadap kandungan kalium (F-hitung = 52,18; p < 0,001). Uji Duncan mengonfirmasi hierarki T₂ > T₁ > T₀ (p < 0,05). Turbinaria sp. fermentasi terbukti efektif sebagai amelioran organik untuk meningkatkan ketersediaan kalium pada tanah ultisol.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh aplikasi biofertilizer berbasis Padina sp. terhadap ketersediaan kalium (K) pada tanah ultisol. Tiga perlakuan digunakan, yaitu tanpa aplikasi Padina sp. (P0), Padina sp. segar (P1), dan Padina sp. fermentasi (P2), masing-masing dengan lima ulangan. Analisis kandungan K dilakukan pada hari ke-3, 7, 10, dan 14 menggunakan ICP-OES. Hasil penelitian menunjukkan bahwa perlakuan Padina sp. fermentasi memberikan peningkatan K tertinggi yaitu sebesar 0,31 cmol/kg. Proses fermentasi mempercepat dekomposisi biomassa dan pelepasan K sehingga ketersediaan unsur tersebut dalam tanah meningkat lebih cepat. Meskipun terjadi sedikit penurunan pada akhir pengamatan, nilai K pada perlakuan fermentasi tetap lebih tinggi dibandingkan perlakuan lainnya. Uji ANOVA satu arah menunjukkan pengaruh nyata (p < 0,01) pada nilai K tanah ultisol. Dengan demikian, Padina sp. fermentasi berpotensi sebagai biofertilizer alami untuk meningkatkan ketersediaan K pada tanah ultisol.

Abstract

The coastal area of Desa Sungai Nibung is a conservation area with high biodiversity. This area has been used for various activities, such as capture and aquaculture fisheries, shipping traffic, and tourism. These activities could affect the waters, ecosystems, and biodiversity condition. Water quality is determined by several parameters, which one of the bioindicators is microalgae. The presence of certain microalgae contributes to the change in the color of the water which indicates the presence of HABS phenomenon. Therefore, this study aimed to determine the composition of microalgae in the waters of Desa Sungai Nibung. Water samples were taken by purposive sampling method in 5 stations with different environmental characteristics. Each station was taken surface water using a plankton net. Microalgae in the samples were then observed with a microscope and their abundance was calculated. The composition of microalgae consisted of 22 genera, belonging to Bacillariophyceae (14 genera), Dinophyceae (7 genera), and Chlorophyceae (1 genus). The Bacillariophyceae dominated the waters with a percentage of 63.66%. Microalgae abundance ranged from 3.94-7,329.25 ind/L with oligotrophic and mesotrophic categories. The diversity index was low to medium (0.74-1.78), Evenness index was low to medium (0.31-0.66), and dominance index was low to high (0.24-0.74).

Abstract

Paloh District is a turtle conservation area designated by the Minister of Maritime Affairs and Fisheries. This conservation area is managed by local community groups and the WWF-Indonesia Foundation under the authority of the West Kalimantan Province Maritime and Fisheries Service. Turtles are protected biota because of their endangered status. However, the community, especially local residents, do not yet have awareness of the importance of protecting this biota and also maintaining the balance of the surrounding ecosystem. Several cases occurred in Paloh, namely poaching for turtle eggs, degradation of turtle nesting beach habitat and marine debris pollution. Therefore, socialization and education on turtle conservation needs to be carried out, especially in the Paloh turtle conservation area. Activity participants are pupils, students and the community. The education and socalization provided includes the types of turtles, their conservation status and the protection efforts that can be taken. The aim of this community services was provided awareness for the community so that they participate in efforts to protect turtles and their habitat. Participants were very enthusiastic in taking part in the entire series of activities. There were five (5) participants who answered the questions correctly and received gifts from the organizing committee.

Abstract

Paloh District is a coastal area which directly borders to Sarawak (Malaysia) and the Natuna Sea. This area has the potential for marine and coastal resources, such as mangrove ecosystems, coral reefs and turtles, so it has been designated as one of the conservation areas in West Kalimantan. To date, in the management of KKP3K Paloh, there are still many challenges, one of them is plastic waste contamination. Plastic waste is a global and very complex problem, because it can have a negative impact on biota, ecosystems and human health. The results of a report from BKSDA in collaboration with the WWF-Indonesia Foundation, found that 21 young turtles were died on Paloh Beach, West Kalimantan due to plastic waste was found in their digestive tract. Plastic accumulation in the aquatic environment occurs when the rate of input of plastic pollution into an area exceeds the rate of natural removal processes. Therefore, it is needed an action to reduce the amount of plastic waste accumulated in coastal and marine areas. This activity aimed to reduce the amount of plastic waste on Sungai Belacan Beach, Paloh District, West Kalimantan. Apart from that, this activity was an effort to strengthen the management strategy for the Coastal and Small Islands Conservation Area (KKP3K) in Paloh, West Kalimantan. Community Service Activities were carried out at Sungai Belacan Beach. The results found the waste types consisting of plastic bottles, glass bottles, medicine bottles, drink cups/packaging, food and beauty product packaging, stereofoam, plastic bags and ropes, fishermen's fishing gear, and wood. Plastic waste has the highest percentage (95%), then wood waste (3%), and other types of waste (2%).

Abstract

Desa Sungai Nibung is a coastal with high biodiversity, so this village has been designated as a conservation area in West Kalimantan with the main conservation target is mangrove. The mangrove ecosystem has an important ecological role, namely as a habitat for marine and coastal biota. A maintained ecosystem will protect the survival of the biota within it. Therefore, managing coastal areas is essential and a shared responsibility. One of the challenges faced in the management process in Desa Sungai Nibung is plastic waste pollution. This waste comes from disposal and runoff from land, which can enter rivers and the sea. Plastic pollution also comes from fishing activities, such as ship traffic, responsive fisheries, and cultivation. This waste needs to be appropriately managed because there is no final waste disposal site (TPA). Household waste and waste from several shops (plastic food and drink packaging) are dumped directly around the building. The accumulation of plastic waste will continue to increase. Therefore, cleanup activities were carried out to reduce plastic waste. Apart from that, this activity aims to educate activity participants about the negative impact of plastic waste on the environment. This community service activity was carried out by a lecturer in Marine Science, FMIPA, Tanjungpura University, who involved students from the Merdeka Belajar Kampus Merdeka (MBKM) program. Beaches and coastal clean-up from macroplastic waste are carried out in residential areas, docks, and areas near fishing activities and ecotourism areas. Implementation of PKM activities consists of permission and coordination, implementation, monitoring, and evaluation. The waste from activities varies from plastic bags, sachet packaging, and food containers to fishing lines. Plastic waste dominates compared to other waste. Participants' understanding concerning plastic waste pollution and its negative impact on the environment and aquatic organisms increased after the activity took place.

Abstract

Mempawah Regency, located on the coast of West Kalimantan, has extensive mangrove potential, including in Sungai Bakau Kecil Village, with major species such as Avicennia, Rhizophora, Bruguiera, Sonneratia, and Nypa. Mangrove ecosystems, known to be among the most productive, have vital roles in social ecology, economy, and culture. However, most mangroves are degraded due to human activities. One approach to restoring degraded mangrove forests is through rehabilitation that involves local communities. This Community Service activity aims to maintain the sustainability of coastal ecosystems, while providing education on mangrove rehabilitation using traditional methods such as bamboo sleeves as one of local wisdom. The activity was carried out on 24-26 May 2024 in the mangrove area of Desa Sungai Bakau Kecil, involving lecturers and students of Marine Science Department, Gemawan Institute, and the local community. Mempawah Regency is experiencing coastline changes due to abrasion and accretion, causing damage to mangrove ecosystems in this region. Mangrove planting activities in Desa Sungai Bakau Kecil using local mangrove Rhizophora sp. with the bamboo sleeve method showed a high growth percentage (80-90%). In addition, the participants' level of understanding of the mangrove rehabilitation program increased after the activity.

Abstract

The research aims to enhance marine literacy and raise awareness among high school students in Mempawah Regency about vital role of mangrove ecosystems in maintaining coastal environmental balance. Limited student understanding has contributed to low participation in conservation efforts. A participatory educational approach was implemented through material presentation, interactive discussion, and marine equipment demonstrations. Questionnaire results indicated that over 90% of participants reported an increased understanding, with most expressing motivation to engage in mangrove conservation activities. These findings highlight the effectiveness of participatory methods in fostering marine literacy and environmental awareness. The program’s success is expected to serve as a sustainable model for environmental education in schools and can be expanded to promote ecological consciousness at the community level.
