Abstract

Kegiatan Program Kemitraan Mayarakat (PKM) bertujuan untuk menghasilkan masyarakat yang mampu mengelola sampah rumah tangga dengan baik, masyarakat yang mau menjaga daerah aliran sungai tempat mereka hidup, bersihnya daerah perairan teluk Manado dari sampah rumah tangga (termasuk sampah plastik), pelestarian biota laut khusunya plankton. Kegiatan PKM ini dilaksanakan di Kelurahan Karame lingkungan 1 dan 2, Kec. Singkil, Kota Manado yang memang sangat memiliki masalah terkait dengan sampah. Kelurahan Karame berbatasan langsung dengan daerah aliran sungai Tondano dan lokasinya juga merupakan tempat berkumpulnya air dari Tondano maupun Sawangan. Walaupun hampir selalu mendapat bencana banjir, sampai saat ini masyarakat Kelurahan Karame belum memiliki kesadaran untuk menjaga lingkungan. Sampah rumah tangga seperti sisa-sisa bahan makanan, sisa-sisa plastik pembungkus makanan ataupun limbah perikanan (insang, jeroan ikan) masih saja terlihat di selokan besar yang ada di Kelurahan Karame ling.1 maupun ling. 2. Dalam mengatasi masalah tersebut, tim telah mengadakan kegiatan berupa penyuluhan tentang “Sampah dan Dampaknya bagi Lingkungan dan Kesehatan”. Tujuan dari kegiatan ini adalah agar masyarakat sadar bahwa sampah akan menjadi masalah bila tidak ditangani dengan benar (dibuang ke DAS Tondano), dan masyarakat khususnya ibu-ibu juga diminta untuk memilah sampah/mendaur ulang sampah sehingga bisa menguntungkan (contohnya mengumpulkan botol aqua untuk dijual). Kegiatan PKM ini akan berlangsung selama 4 bulan (Agustus – November 2018). Berdasarkan kegiatan penyuluhan tersebut, nampak bahwa warga lebih termotivasi untuk mulai memilah sampah organik dan non-organik yang bernilai ekonomis sebagai potensi usaha yang ramah lingkungan.___________________________________________________________________________Kata Kunci: Sampah, Karame, Pemberdayaan Masyarakat, Pengelolaan Sampah

Abstract

During rainy season, a various type of litter can enter the ocean through rivers. This is a significant contributor to the amount of marine litter in the waters. In order to access the type, composition, and density of the litter during rainy season, this study was conducted in Manado Bay, North Sulawesi. The observation was done on the litter stranded on the beach, and they were classified into two different size groups, macro (>2,5 cm)- and meso (0,5-2,5 cm)-sizes. Malalayang Beach and Bailang Beach were chosen for the location of the study. Litter type, composition, and density was evaluated according to National Marine Litter Monitoring Guide. The result showed that there were 7 types of macro-size and 6 types of meso-size marine litter in Malalayang Beach and it was dominated by glass and ceramic for both sizes. In Bailang Beach, 9 types of macro-size and 7 of meso-size were found, and it was dominated by plastics. It can be concluded that various type of marine litter present in Manado Bay, both macro- and meso- sizes, during the rainy season. The highest composition was the glass and ceramics type. However, the highest density was the plastic type.---Pada musim hujan, berbagai jenis sampah dari daratan masuk ke perairan pantai melalui sungai. Hal ini merupakan penyumbang signifikan bagi jumlah sampah laut di perairan. Untuk menilai jenis bahan, komposisi, dan kepadatan sampah laut pada musim hujan, penelitian ini dilakukan di Teluk Manado, Sulawesi Bagian Utara. Pengamatan dilakukan terhadap sampah laut yang terdampar di pantai (beach litter), berukuran makro (> 2,5 cm) dan meso (0,5-2,5 cm), di dua lokasi, yaitu Pantai Malalayang dan Pantai Bailang. Sampah laut dievaluasi menggunakan Pedoman Nasional tentang Pemantauan Sampah Pantai. Hasil penelitian menunjukkan, sampah laut jenis plastik, kaca & keramik, busa plastik, kertas & kardus, logam, karet, kayu, kain, dan bahan lainnya, baik berukuran makro maupun meso ditemukan di perairan. Di Pantai Bailang, komposisi sampah laut berukuran makro dan meso didominasi oleh jenis bahan plastik; tetapi, di Pantai Malalayang didominasi oleh jenis kaca & keramik. Demikian juga untuk kepadatan sampah laut di Pantai Bailang, jenis bahan plastik mendominasi, baik sampah berukuran makro maupun meso. Sedangkan di Pantai Malalayang, jenis kaca & keramik mendominasi kepadatan sampah laut pada semua ukuran. Selanjutnya, dapat disimpulkan, pada musim hujan, berbagai jenis bahan sampah laut berada di Teluk Manado, baik berukuran makro maupun meso. Komposisi terbesar untuk ukuran makro dan meso ialah jenis bahan kaca & keramik. Namun, kepadatan tertinggi untuk ukuran makro dan meso ialah sampah jenis bahan plastik.

Abstract

Information about oceanographic conditions is important to determine the fertility level of waters. Oceanographic parameters in water can be influenced by global climate factors, one of them is the ENSO (El Niño Southern Oscillation) phenomenon. There have been many studies on the effect of ENSO phenomenon on oceanographic variability, but no studies have been carried out in the waters of North Sulawesi. This study aims to determine the effect of the ENSO phenomenon on the variability distribution of oceanographic parameters in North Sulawesi waters. The data used for this study were Sea Surface Temperature (SST) and chlorophyll-a from the AQUA-MODIS imaging results, wind reanalysis results from ECMWF, and Nino 3.4 index as an indicator of ENSO from NOAA. The data were processed and analyzed using quantitative analysis methods in the form of graphics. The results showed an indirect effect of the ENSO phenomenon on SST parameters and chlorophyll-a. This is because the effect of the ENSO phenomenon occurred in a certain period:  when strong El Niño triggered low temperatures of sea surface and high chlorophyll-a, and when La Niña was strong it triggered high temperatures of sea surface and low chlorophyll-a. Meanwhile, the wind speed pattern showed an insignificant effect because the wind speed was still dominated by the influence of the monsoon pattern.Indonesian title: Hubungan antara El Niño Southern Oscillation (ENSO) dan parameter oseanografi di perairan Sulawesi Utara

Abstract

Mitigation of marine debris in Manado City, the city which is situation in front of the Manado bay, is very important in order to prevent its effect on the coastal communities and as well as for the aesthetics point of view. That activities can directly protect the ecosystem of Bunaken Marine Park (BMP), and can become an important part of the marine waste management activities especially in supporting the commitment of Indonesian government to reducing plastic waste in the sea by 70% by 2025. For this reason, a marine waste management is needed and it should be prepared based on the academic study that are comprehensive and holistic as well as effective and efficient, and also suitable for environmental condition in Manado City. The study was aimed to formulate best options for the existing marine waste management in Manado City. By using qualitative-descriptive and content-analysis methods, four aspects of managemet were studied, and they are 1) public awareness, 2) institutional arrangements, 3) regulations, policies and management plans, and 4) waste management guidelines. The data obtained were quantitatively and qualitatively analyzed. The public awarenes was qualitatively analyzed by using two indicators, community concern and community preference. The existing marine waste management was presented based on studied aspects and the best option was proposed as recommendation for marine waste management in Manado City.

Abstract

Enzymes are important in the technology industry and hydrolytic enzymes, such as chitinase and protease are commonly used for it. Various types of microorganisms such as bacteria can produce hydrolytic enzymes.  Sponge-associated bacteria are excellent sources of extracellular hydrolytic enzymes because the surface and internal spaces of sponges are richer in nutrients. The aim of this study was to isolate and screen the bacteria of the sponge Dragmacidon sp symbiotic from Manado Bay, North Sulawesi that producing chitinase and protease   Symbiont bacteria were grown in Zobell 1226 E medium with a dilution of 10-4. Bacterial isolation was carried out based on the morphological characteristics of the colony. Chitinase and protease activity was carried out by growing each bacterial isolate in chitin and protein media at 36oC for 48 hours. Chitinase and protease activities were indicated by the formation of a clear zone around the bacterial colony, however, the clear zone for chitinase activity was observed after pouring the Lugol's solution. Based on this study, 8 isolates bacteria of the symbiotic spongy Dragmacidon sp from Manado Bay, North Sulawesi were isolated based on morphological characteristics. The colony of the bacteria is generally white with an irregular shape. Four isolates, namely 1, 2, 3, and 8 had chitinase activity with chitinolytic indexes were 1.7; 1.5; 1.4, and 1.3, respectively. Six isolates, namely 1, 2, 3, 4, 5, and 6 had protease activity with proteolytic indexes were 1.4; 1.8; 3.1; 1.3; 1.8; and 2.5, respectively.Keywords: Bacteria; Chitinolytic; Proteolytic; Symbiont; SpongeAbstrakEnzim menempati posisi penting dalam bidang teknologi dan industri.

Abstract

The purpose of this study was to identify sea slugs L. pallescens taken from two different mangroves, namely Rhizophora mucronata and Avicennia marina in Tongkaina waters, Bunaken District, Manado City based on morphology and anatomy as well as shell color. Identification of mangroves and sea slugs refers to the identification book. The results obtained were L. pallescens species with elongated and tapered morphology at the end of the shell measuring 0.3-2.7 cm. The operculum is purple. The color of the shell obtained was 66.85% consisting of dark colors (black, black, orange, brown and gray spots), occupying the stems and roots of the mangrove, while the light colors (yellow, yellow, dark spots and red) were found to be 33.15%, occupying the leaves and stems of mangroves. The high survival rate of L. pallescens was found in the mangrove roots. This species was found in R. mucronata by 65.26% while in A. marina only 34.74%, this could be caused by differences in the shape of the mangrove roots.Keywords: L. pallescens; Mangrove; Shell color; MorphologyAbstrakTujuan penelitian ini adalah mengindentifikasi siput laut L. pallescens yang diambil dari dua mangrove berbeda yaitu Rhizopora mucronata dan Avicennia marina di perairan Tongkaina, Kecamatan Bunaken, Kota Manado berdasarkan morfologi dan anatomi serta warna cangkang.

Abstract

Seaweed can produce bioactive compounds such as antibacterial. Seaweed co-exists with bacteria endophytes. Entophytic bacteria are bacteria that live in host tissues and have the ability to protect the host itself by producing antibacterial compounds against pathogens. Therefore, the endophytic bacteria of seaweed symbionts can be utilized to produce antibacterial compounds. Bacteria can be mass-cultured because of their fast-growing characteristic. The aim of this study was to determine the antibacterial activity from endophytic symbiont bacteria on seaweed Gracilaria verrucosa originated from Batu Meja Tongkaina Beach, North Sulawesi. Isolation of bacteria was carried out by dilution steps from 101 to 10־3 times, then cultivation on Nutrient Agar media to obtain a single colony of the bacteria. Antibacterial activity was tested used paper disc diffusion method. The pathogens used were bacterial strains of Escherichia coli, Staphylococcus aureus, Streptococcus mutans, and Salmonella typhi. Moreover, antibiotics were used as positive controls. The antibacterial ability of the symbiotic bacteria was measured based on inhibition zones around the paper disc containing the isolates of endophytic bacteria. A total of 6 endophytic bacterial isolates were found, namely isolate B, C, D, E, F and G, characterized by different morphological features. The results showed that isolates B and C having inhibition zone of 0.5 – 1.0 mm against S. typhi, indicating that these two isolates produce antibacterial compounds with a weak ability  against S. typhi.

Abstract

Taman Nasional Bunaken (TNB) is located in North Sulawesi Province, Republic of Indonesia. TNB offers an exploration experience of marine tourism such as snorkeling and diving. This study was conducted to determine the statistics and correlation of weather parameters on hydrodynamics in the waters of the small island of TNB. This information can be used by marine tourism users. The weather data studied are wind direction and speed. The hydrodynamic conditions studied were wave height and ocean currents. Respondent surveys were also conducted on tourist users at the research sites. The wind direction for the period January - April is dominant from the Northeast, May - September is dominant from the East to the South, October tends to be evenly distributed from the East to the West, and November - December is dominant from the West. Significant wind speeds that occur in January, February, and March range from 18 – 36 knots. The average wave height shows a significant value in January – March, tends to be lower in April – June, fluctuates in July – November, and increases again in December. The maximum current velocity at a sea depth of 16.5 m is stronger than the maximum speed at a depth of 0.5 m and 8.0 m in January – April, and May August. The correlation value of wind speed and sea wave height is significant at 0.96 and the correlation between wind speed and the current speed is 0.74. These results indicate that there is a strong -very strong relationship between parameters. The survey results show that wind speed, wave height, and ocean currents have the same pattern. January, February, November, and December are the months of extreme or bad weather and hydrodynamic conditions.Keywords: Taman Nasional Bunaken, Weather, Hydrodynamics, CorrelationAbstrakTaman Nasional Bunaken (TNB) terletak di Provinsi Sulawesi Utara, Negara Republik Indonesia.
