Abstract

Mangrove (bakau) is one of the coastal plants that might function socially, ecologically and economically. One of the coastal areas of East Kalimantan that has experienced damage due to human activities is in Bontang City, specifically Telok Bangko. Therefore, planting bakau seedlings is one of the efforts to maintain the bakau ecosystem in the coastal areas of Bontang City. The purpose of this community service activity is to increase knowledge and understanding of the importance of mangrove in coastal areas by planting mangrove seedlings. This community service activity was carried out on September 29, 2024 in the Telok Bangko mangrove tourism area, Bontang City. The method used in this activity was lecture and followed by direct practice in the field. The results of this activity were 500 mangrove seedlings (Rizophora mucronata) were planted at the location of the activity by students and academics of Mulawarman University. The results of this activity could increase knowledge and understanding for each participant in determining the right planting location, type, how to plant mangroves and evaluate activities. This activity is also expected to benefit the community both economically and ecologically in the Telok Bangko mangrove area. The process of evaluating activities must be carried out to support the success of this activity, such as maintenance, periodic data collection (monitoring) of mangrove seedlings (% survival rate) that have been planted by participants.Mangrove (bakau) merupakan salah satu tumbuhan pesisir yang dapat berfungsi secara sosial, ekologi dan ekonomi. Salah satu kawasan pesisir Kalimantan Timur yang  telah mengalami kerusakan akibat aktivitas manusia terdapat di Kota Bontang, khususnya Telok Bangko. Karenanya, menanam bibit bakau merupakan salah satu usaha untuk mempertahankan ekosistem bakau di wilayah pesisir kota Bontang. Tujuan dari kegiatan ini adalah untuk meningkatkan pengetahuan dan pemahaman tentang pentingnya bakau di wilayah pesisir dengan cara menanam bibit bakau. Kegiatan pengabdian masyarakat ini dilakukan pada tanggal 29 September 2024 di kawasan wisata mangrove Telok Bangko, Kota Bontang. Metode ceramah dan praktek langsung merupakan metode yang dilakukan di kegiatan pengabdian masyarakat ini. Hasil kegiatan yang didapatkan dari kegiatan ini adalah bibit bakau (Rizophora mucronata) telah ditanam sebanyak 500 bibit di lokasi kegiatan oleh para siswa dan akademisi Universitas Mulawarman. Hasil kegiatan ini dapat meningkatkan pengetahuan dan pemahaman kepada setiap  peserta dalam penentuan lokasi penanaman, jenis, cara menanam bakau dan evaluasi kegiatan secara tepat. Kegiatan ini juga diharapkan dapat bermanfaat bagi masyarakat baik secara ekonomi dan ekologi di kawasan mangrove Telok Bangko. Proses evaluasi kegiatan harus dilakukan untuk mendukung keberhasilan dari kegiatan ini, seperti pemeliharaan, pendataan berkala (monitoring) bibit bakau yang hidup (% survival rate) yang telah ditanam oleh peserta kegiatan.

Abstract

Education is one indicator of a country's progress, because it has improved the quality of human resources. One of the Educational activities in the university is joint practicums to improve students' understanding of critical thinking patterns and values. The purpose of this practicum was to examine and analyze the ability of essential patterns of thinking, level of understanding of theory and method, and student learning outcomes as well in the study programme of Marine Science, Mulawarman University. Practicum activities were conducted in Malahing village, Bontang City in November 2022. A total of 52 students took part in the activities. All data in this activity were collected from initial critical thinking skills tests (pre-test) and after (post-test), score from practicum’s report, and participants' perceptual responses in the form of online questionnaires. It was found that the student's critical thinking skills in this activity were in the moderate category based on N-Gains score (0,46). In General, the percentage of understanding and student learning outcomes was in good category (71-84). Based on the student responses, about 92.3% of students were enthusiastic and happy with the practicum learning method. Thus, joint practicum activities might influence increasing student understanding and grades.

Abstract

Human activities in the Somber River area of Balikpapan, such as settlements, industry, shipping, and fisheries, have the potential to cause cadmium (Cd) contamination, threatening the mangrove ecosystem and aquatic biota. This study aimed to determine the concentration and contamination level of Cd in the sediments of the Somber River, Balikpapan. Sediment samples were systematically collected from four stations representing different anthropogenic influences, using a hand corer (50 cm depth). Cadmium concentration was analyzed using Atomic Absorption Spectrophotometry (AAS) following acid digestion. It was found that the Cd concentrations ranged from 0.04 to 1.01 µg/g, with an average of 0.37 ± 0.29 µg/g dry weight. All values were below the national sediment quality guideline. The accumulation of Cd showed an increasing trend with greater sediment depth. The calculated Contamination Factor (CF) indicated low to moderate contamination levels at all stations. Overall, the sources of Cd along the Somber River originate from both natural processes and anthropogenic activities from the land.

Abstract

Kajian terkini mangrove di Mangrove Bontang Park terbatas pada kajian perubahan luasan area mangrove, namun belum menghitung nilai stok karbon. Penelitian ini bertujuan untuk mengetahui stok karbon yang tersimpan di biomassa mangrove di lokasi tersebut dan menganalisis hubungannya dengan sebaran tingkat kesehatan mangrove. Pengambilan data dilakukan di pada bulan Februari 2023. Sebaran zona penelitian berdasarkan model sebaran indeks kesehatan mangrove menggunakan data citra Sentinel-2A yang dibagi menjadi 3 zona yaitu Zona Excellent, Zona Moderate, dan Zona Poor. Data lapangan yang diambil antara lain jumlah tegakan, persentasi tutupan kanopi dan diameter batang pohon. Aplikasi MonMang 2.0 digunakan dalam mengukur tingkat kesehatan mangrove secara langsung di lapangan. Stok karbon pada biomassa mangrove dihitung menggunakan persamaan alometrik biomassa mangrove dan faktor konversi biomassa-karbon. Hasil validasi indeks kesehatan mangrove menggunakan MonMang 2.0 menunjukkan bahwa tingkat kesehatan mangrove di lokasi penelitian termasuk dalam kategori cukup baik. Stok karbon pada biomassa atas (AGB) diestimasi sebesar 180,74 MgC/ha dan stok karbon biomassa bawah memiliki rata-rata 102,29 MgC/ha dengan total 283,04 MgC/ha. Hasil analisis data menunjukkan tidak terdapat hubungan signigikan antara stok karbon pada biomassa mangrove dan indeks kesehatan mangrove. The recent study of mangroves in Bontang Mangrove Park was limited in studying changes in mangrove area, but the carbon stocks were not quantify. This research aimed to estimate the carbon stock stored in mangrove biomass and to analyze its relationship with the mangrove health distribution in there. The distribution of research zones were based on the mangrove health index distribution model by using Sentinel-2A image data. The model result divided into 3 zones that were Excellent Zone, Moderate Zone and Poor Zone. Field data collection was done in February 2023. Data collection included the number of stands, canopy cover and diameter at breast height. The MonMang 2.0 application was used to measure the health level of mangroves, directly in the field. Carbon stock in mangrove biomass was calculated by using the mangrove biomass allometric equation and the biomass-carbon conversion factor. The validation results of the mangrove health index using MonMang 2.0 showed that the level of mangrove health at the research location was moderate. Carbon stock in above-ground biomass (AGB) estimated at 180.74 MgC/ha and below-ground biomass was 102.29 MgC/ha with a total carbon stock was at 283.04 MgC/ha. No significant relationship was found between carbon stocks in mangrove biomass and the mangrove health index.
