Abstract

Gastropods are one of the macrobenthos associated with seagrass ecosystems. The purpose of this research is to determine the structure of the gastropod community in the seagrass ecosystem in the Bama waters of Baluran National Park. Collecting data on gastropods in seagrass ecosystems uses quadrat transects. The research was conducted in February 2024. Based on the research results, it was found that the richness of gastropod species in the seagrass ecosystem in the waters of Baluran National Park was in the low category at each station. The gastropod species diversity index value in this study was in the low category. The evenness index has a stable category, while the dominance index in this study does not have species dominance in gastropods. Seagrass density in this study was in the rare and dense categories.

Abstract

Upaya penanaman mangrove menjadi sangat penting bagi kelestarian ekosistem pesisir. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan kesadaran masyarakat tentang pentingnya mangrove dan melibatkan mereka dalam upaya pelestarian lingkungan. Melalui penanaman mangrove, diharapkan masyarakat dapat memahami peran penting mangrove dalam menjaga keseimbangan ekosistem pesisir dan meningkatkan kualitas hidup. Kegiatan penanaman mangrove dapat memberikan dampak positif bagi lingkungan dan masyarakat sekitar serta menjadi langkah awal dalam upaya pelestarian ekosistem mangrove. Penanaman mangrove efektif untuk menstabilkan pesisir dari erosi dan sedimentasi serta meningkatan keanekaragan hayati. Mangrove yang baru ditanam berfungsi sebagai habitat bagi berbagai jenis biota laut dan satwa liar. Penanaman mangrove memberikan manfaat sosial ekonomi bagi masyarakat diantaranya peningkatan pendapatan dari hasil perikanan dan pengembangan ekowisata.

Abstract

Water quality becomes an important parameter to observe in aquaculture activities to understand its impact on fish growth. The objective of this research is to determine the effect of plankton density and the parameters of pH, temperature, and dissolved oxygen on the growth of Nilem fish (Osteochilus vittatus). The research was conducted from September 2024 to October 2024. The method used is quantitative, which includes plankton density, Nilem fish weight, and water quality, with the results presented as numerical data in the form of tables and graphs. The average temperature of the Nile tilapia cultivation pond is 32°C, dissolved oxygen with an average value of 4.95, and pH with an average value of 6. The highest fish growth rate was in the first week at 8.39%, followed by the fourth week at 7.29%, while the growth rates in the second and third weeks did not reach 5%. The results of the plankton density regression analysis found that 6% of the specific growth rate is influenced by this factor, while 94% is influenced by other factors. The correlation coefficient (r) obtained is 0.24 and the value of b = -11.611x (negative relationship). Based on PP No. 22 of 2021, the water quality value of this nilem fish farming pond still meets the water quality standard, but compared to the water quality for nilem fish farming, the average water quality value measured in this farming pond does not meet the standard. The observed plankton density over 4 weeks showed fluctuating results, and the growth rate of Nile tilapia also exhibited fluctuating results. The relationship between plankton density and the growth rate of Nile tilapia is classified as weak.

Abstract

Coral reefs are one of the ecosystems with the highest biodiversity. The purpose of this study was to determine the relationship of current velocity has on primary productivity in coral reef ecosystems. Current velocity measurements using a current meter and primary productivity measurements using the Winkler method by ƒincubated for 5 hours. The results obtained from this study are that current velocity has an effect on primary productivity in coral reef ecosystems, R value 0.895 and R Square shows 80.1%. The significance value obtained Sig = 0,04, which means less than 0.05, it can be interpreted that the effect of current velocity on primary productivity is strong category. Based on the study results obtained, more research is necessary to find out how much the velocity of the current affects the primary productivity of the coral reef.

Abstract

The pedada fruit (Sonneratia alba), locally known as posi-posi, has potential as a raw material for herbal tea with various health benefits, such as lowering cholesterol, relieving gout, providing antioxidant effects, reducing gastric acidity, and supporting organ health. However, mangrove tea has not yet been widely marketed in North Maluku, and it is not available as a local tourism souvenir. This Community Service Program (PKM) aimed to: (i) increase partners’ knowledge of mangrove fruit as a business opportunity, (ii) apply appropriate technology in tea processing, and (iii) produce high-quality mangrove tea variants with market value. The implementation stages included: (1) knowledge delivery through presentations and discussions, (2) mangrove exploration along the Guraping tourism tracking route, and (3) demonstration of mangrove tea processing. The product was developed into five variants: TeOry, Tebal, TeGo, TTM, and PosiNaga. Each variant was packaged in tea bags and boxes, then evaluated using hedonic organoleptic testing based on color, aroma, taste, and texture. The results indicated that mangrove tea has promising potential as a distinctive tourism souvenir and as a new business opportunity for local communities.

Abstract

Akumulasi sampah organik  seperti kayu, ranting, dan dedaunan  di pesisir Pantai Kastela  Kota Ternate tidak terkelola dengan baik, yang menyebabkan pencemaran lingkungan, merusak ekosistem, dan berdampak negatif pada sektor pariwisata. Kegiatan pengabdian masyarakat ini dilakukan dengan memberikan pelatihan pengolahan sampah kepada Kelompok Sadar Wisata (Pokdarwis) Gam Lamo. Pelatihan ini memperkenalkan inovasi teknologi pengolahan sampah menjadi briket sebagai bahan bakar alternatif yang ramah lingkungan dan bernilai ekonomi. Metode yang digunakan meliputi sosialisasi, penyuluhan, dan pelatihan teknis. Berdasarkan evaluasi menggunakan pre-test dan post-test, terjadi peningkatan pengetahuan peserta sebesar 90%, dengan skor rata-rata pre-test 52 dan post-test 94. Hasil ini menunjukkan bahwa pelatihan berhasil meningkatkan pemahaman dan keterampilan peserta. Selain mengurangi pencemaran dan emisi karbon, pembuatan briket juga menciptakan peluang usaha baru dan mendukung kemandirian ekonomi Masyarakat. Hal ini membuktikan bahwa solusi berbasis komunitas efektif dalam mencapai keberlanjutan lingkungan dan kesejahteraan masyarakat di wilayah pesisir.
