Abstract

A study to show bioaccumulation and biotransfer processes of mercury (Hg) has been done in controlled experimental chambers. Three groups of aquatic organisms, namely phytoplankton Nannochloropsis oculata representing producers, fish Lebistes (Poecilia) reticulatus representing herbivorous consumers, and fish Tiger Fish Symphysodon sp. representing carnivorous consumers, were contaminated by two different concentrations of Hg, in form of methylmercury (MeHg), such as 22.6 ppb as Treatment 1 and 79.1 ppb as Treatment 2. Controls were setup for all experiments. The result showed that bioaccumulation process occurred in the experiments and the amount of MeHg accumulated was depended on the amount of supplied MeHg. Biotransfer of MeHg was also indicated in this study. The highest biotransfer of MeHg occurred between the phytoplankton and the herbivorous fish pathway. The study concludes that bioaccumulation and biotransfer processes of MeHg occurred in the experimental pathway and the amount of mercury accumulated and transferred was depended on the amount of mercury supplied.

Abstract

A study on water quality status of three riverine systems, S. Bailang (SB), S. Maasing (SM), and S. Tondano (ST), in coastal city of Manado, North Sulawesi Province, has been conducted to measure several water quality parameters, to analyse source and quality of wastewater discharge, and to assess the status of the rivers related to the water quality. Measurement of the parameters was conducted using three indicators, i.e. organic (BOD5) and in-organic (N-NO3 and P-PO4), and pathogenic microorganism (Escherichia coli [EC] and total coliform [TC]). The result showed that the level of water quality varied between the rivers. The average level of water quality (based on the observed parameters) in SB, respectively, was 0.317 mg/l, 0.093 mg/l, 2 mg/l, >2420 MPN, and  >2420 MPN; in SM, respectively, was 0.029 mg/l, 1.859 mg/l, 17.7 mg/l, >2420 MPN, and >2420 MPN; and in ST, respectively, was 0.299 mg/l, 0.252 mg/l, 3.5 mg/l, >2420 MPN, and >2420 MPN. The level of water quality between the rivers was not significantly different (p>0.05), except based on the parameter of N-NO3 which was significantly different (p<0.01). The status of the observed rivers varied based on the classes of their water utilities (according to the Government Regulation of Indonesia, No. 82, 2001); mostly was "unsuitable". Kajian tentang status kualitas air di 3 perairan sungai di kota pesisir Manado, S. Bailang (SB), S. Maasing (SM), dan S. Tondano (ST), Provinsi Sulawesi Utara, telah dilakukan yang bertujuan untuk mengukur beberapa parameter kualitas air, menganalisis sumber dan kualitas buangan limbah domestik, dan menilai status ketiga perairan sungai tersebut. Tiga indikator digunakan, yaitu: bahan organik (BOD5), bahan anorganik (N-NO3 dan P-PO4), dan mikroorganisme patogenik (Escherichia coli [EC] dan coliform total [TC]). Hasil kajian menunjukkan bahwa tingkat kualitas air perairan tersebut berbeda-beda. Konsentrasi rerata parameter kualitas air  (BOD5, N-NO3, P-PO4, EC, dan TC) di SB, berturut-turut, sebesar 0.317 mg/l, 0.093 mg/l, 2 mg/l, >2420 MPN, dan >2420 MPN; di SM, berturut-turut, sebesar 0.029 mg/l, 1.859 mg/l, 17.7 mg/l, >2420 MPN, dan >2420 MPN; dan di ST, berturut-turut, sebesar 0.299 mg/l, 0.252 mg/l, 3.5 mg/l, >2420 MPN, dan >2420 MPN. Konsentrasi kualitas air ketiga sungai tersebut tidak berbeda secara signifikan (p>0.05), kecuali parameter N-NO3 (p<0.01). Secara umum, kondisi kualitas air ketiga sungai tersebut, menurut Peraturan Pemerintah No. 82, 2001) berada dalam status “tidak cocok” untuk peruntukannya.

Abstract

Title (Bahasa Indonesia):Kontaminasi merkuri (Hg) di Teluk Manado, Sulawesi Utara, IndonesiaArtisanal gold minings, which are situated in the highlands of the northern part of Sulawesi Island,use mercury (Hg) to extract gold and dischargetheirs tailings into rivers; one of the rivers(Bailang River) is connected to Manado Bay. This could cause Hg contamination into the bay. This study aimed to assess the contamination of Hg in the aquatic ecosystem of the bay. For the assessment, the bay was divided into 2 parts, namely the North and the South, and the contamination was assessed by measuring the total Hg concentration in sediments and fishes. Determination of Hg concentration refers to the Indonesian National Standard (SNI) 01-2896-1992 and Guidance of Balai Riset dan Standarisasi Industri Manado. The results showed that the range of Hg concentrations in fish varied by species; in the northern part of the bay: Holocentridae (0.1144-0.1151 ppm), Siganidae (0.0020-0.0034 ppm), Apogonidae (0.0461-0.050 ppm), and Nemipterus (0.0142-0.0144 ppm ). While in the southern part of the bay: Holocentridae (0.1090-0.1104 ppm), Siganidae (0.160-0.164 ppm), Apogonidae (0.1280-0.1291 ppm), Nemipterus (0.0522-0.0530 ppm) , and Priacanthus sp. (0.0194-0.0210 ppm). The average concentration of Hg in sediments of the bay around river mouths varied based on location, i.e. Bailang River was 0.0502 ppm, Sario River was 0.0270 ppm, Bahu River was 0.0615 ppm, and Malalayang River was 0.0143 ppm.Pertambangan emas rakyat menggunakan merkuri (Hg), yang berada di daerah dataran tinggi bagian Utara Pulau Sulawesi, membuang limbah tailing ke sungai menuju ke laut; satu dari sungai tersebut (Sungai Bailang) bermuara ke Teluk Manado. Hal ini dapat menyebabkan kontaminasi Hg ke lingkungan perairan teluk. Penelitian ini bertujuan untuk menilai kontaminasi Hg di ekosistem perairan teluk tersebut. Untuk penilaian, perairan teluk dibagi 2 bagian, yaitu bagian Utara dan Selatan, dan kontaminasi dinilai dengan cara mengukur konsentrasi Hg total pada sedimen dan ikan. Penentuan konsentrasi Hg mengacu Standar Nasional Indonesia (SNI) 01-2896-1992 dan Panduan Balai Riset dan Standarisasi Industri Manado. Hasil penelitian menunjukkan, bahwa kisaran konsentrasi Hg dalam ikan bervariasi berdasarkan jenis; dibagian Utara teluk: Holocentridae(0,1144-0,1151 ppm), Siganidae (0,0020-0,0034 ppm), Apogonidae (0,0461-0,050 ppm), dan Nemipterus (0,0142-0,0144 ppm).Sedangkandi perairan bagian Selatan teluk: Holocentridae (0,1090-0,1104 ppm), Siganidae (0,160-0,164 ppm), Apogonidae (0,1280-0,1291 ppm), Nemipterus (0,0522-0,0530 ppm),dan Priacanthus sp.(0,0194-0,0210 ppm). Konsentrasi rata-rata Hg di sedimen perairan teluk sekitar muara Sungai Bailang sebesar 0,0502 ppm, muara Sungai Sario sebesar 0,0270 ppm, muara Sungai Bahu sebesar 0,0615 ppm, dan muara Sungai Malalayang sebesar 0,0143 ppm.

Title (Bahasa Indonesia): Efektivitas Pengelolaan Taman Nasional Bunaken The important values of Bunaken National Park were gathered through interviews with80 respondents in order to obtain local people’s opinion of the marine park. Results showed that the most important value was coral reefs,holding 68.75% of the respondents’ opinion. Moreover, they put the environmental characteristics, such as fish, biodiversity, and mangrove, as major values of Bunaken National Park. Many respondents mentioned the economic values in relation with tourism business. As many as 11.25% of the respondents claimed that the presence of management and its programs was main value of the marine park. The respondents’ opinion  concerning the threat on the major values of Bunaken National Parkfound that nearly all respondents mentioned several deleterious behaviors that could directly demolish natural environmental values, such as fish blasting, fish poisoning, pollution and illegal mangrove cutting.  Illegal entry of the zonation and excessive exploitation from commercial fishing operations or fish netting, and low awareness  were also found. In addition, 8.75% of the respondents claimed that economic or poverty issues were major threats on Bunaken National Parkvalues, and 5% thought that government policy was the serious threat.This study revealed that Bunaken National Park has been effectively managed. It is indicated by a good patrol system and better social economic condition of the communities living inside the park.Hasil penelitian menunjukkantentang pandangan masyarakat lokal terhadap nilai-nilai penting Taman Nasional Bunaken, yang dilakukan melalui wawancara terhadap 80 responden untuk mendapatkan daftar apa saja yang menurut mereka nilai-nilai paling penting dari Taman Nasional Bunaken.

Abstract

Title (Bahasa Indonesia): Strategi pengelolaan untuk daerah penyelaman berdasarkan persepsi stakeholder di Pulau Bunaken, Sulawesi Utara, Indonesia Bunaken Island is one of the island located in the Bunaken National Park, North Sulawesi, Indonesia. Most of the diving activities are in the waters of Bunaken Island, in which the management involves stakeholders (public, tourists, policy makers, NGOs, and academia). This study used questionnaires as a research instrument to obtain primary data, while secondary data were used as a complement to formulate an alternative strategy, using SWOT analysis. Based on the stakeholders’ perception, dive site management strategies covered research development on environmental issues, regulation availability, carrying capacity and information, community empowerment in addressing environmental problems, coordination among stakeholders for institutional issues and the environment, and improvement of service managing institutions in terms of organizational management and risk management. The study recommended the need for a clear management strategy, the necessity of doing research for regional development strategies/ locations for both diving and other potentials, the need of good marketing strategy, and the need for tourism activities diversification. Pulau bunaken merupakan salah satu pulau yang berada di dalam Taman Nasional Bunaken, Sulawesi Utara, Indonesia. Sebagian besar aktivitas penyelaman berada di Pulau Bunaken di mana dalam pengelolaannya melibatkan stakeholder (masyarakat, wisatawan, pengambil kebijakan, LSM, dan akademisi). Penelitian ini menggunakan instrumen kuesioner sebagai alat pengumpul data primer; data sekunder dikumpulkan sebagai pelengkap untuk merumuskan alternatif strategi, menggunakan analisis SWOT. Hasil analisis menunjukkan, secara umum, bahwa strategi pengelolaan daerah penyelaman, berdasarkan persepsi stakeholder, meliputi: pengembangan penelitian untuk isu-isu lingkungan; ketersediaan regulasi, pengelolaan pengunjung (daya dukung) dan informasi; pemberdayaan masyarakat dalam mengatasi masalah lingkungan; koordinasi antar stakeholder untuk isu-isu kelembagaan dan lingkungan; dan peningkatan pelayanan lembaga pengelola dalam hal manajemen organisasi maupun manajemen resiko. Penelitian ini merekomendasikan perlu adanya strategi pengelolaan yang jelas, perlu dilakukan penelitian untuk strategi pengembangan daerah/lokasi untuk objek wisata baik wisata selam maupun wisata lainnya, perlu strategi pemasaran yang baik, dan perlu diversifikasi aktivitas kegiatan pariwisata.

Abstract

Mangrove gives major contributions to fishery production; however, due to an increasing demand of space for human activities, mangrove area is changed to many forms, such as settlement, industry, and recreation; beside lack of data and information available (biophysics, socio-economic, and culture). These may cause economical and ecological conflicts. This condition is currently happened in Marine Tourism Park of Kupang Bay (MTPKB). Accordingly, this study aims to analyze community structure of mangrove at MTPKB using survey method to observe mangrove vegetation and exploitation impact by community. In this study, 16 species of 9 families were found with categorized density from “rare” (20 individual/hectare) to “dense” (5.450 individual/hectare). The ecosystem was found has low diversity; it was due to high dominant index. Rhyzophora apiculata and Sonneratia alba were found two species which have big role in the marine park© Mangrove memberikan kontribusi yang besar terhadap produksi perikanan; namun, oleh karena kebutuhan manusia yang semakin meningkat, daerah mangrove dirubah menjadi daerah pemukiman, industri, dan rekreasi; di samping kurangnya data dan informasi yang tersedia. Hal ini dapat menimbulkan konflik secara ekonomi dan ekologi. Kondisi ini sedang terjadi di Taman Wisata Alam Laut Teluk Kupang (TWALTK). Oleh karena itu, penelitian ini dilakukan di mana bertujuan menganalisis struktur komunitas mangrove di TWALTK dengan menggunakan metode survei untuk melakukan pengamatan terhadap vegetasi mangrove dan aktifitas masyarakat dalam memanfaatkannya. Dalam penelitian ini ditemukan 16 jenis mangrove dari 9 famili dengan kerapatan terkategori dari ‘jarang’ (20 pohon/hektar) hingga ‘padat’ (5.450 pohon/hektar). Keanekaragaman ekosistem tersebut rendah karena tingginya nilai dominasi. Jenis Rhyzophora apiculata dan Sonneratia alba merupakan jenis yang memberikan pengaruh besar terhadap komunitas mangrove di taman wisata alam laut tersebut©
