Water is a major component of life processes on earth, good quantity and quality of water is highly coveted by humans. River as one type of waters and become a living medium for aquatic organisms, to measure the level of water pollution one of them by using bioindicator method. Bioindicators are organisms that have biological responses that can indicate the entry of certain pollutants in the environment. The purpose of this research is to know river pollution based on Nutrition Value Coeficient (NVC) fish and Makrozoobenthos that live in it. The value of NVC (Nutrition Value Coefficient) of fish varies on each station in the downstream and upstream segments of the Yeh Sungi river, this illustrates that at each station and on different river segments shows different levels of pollution. Waters with clean categories up to the contaminated waters will be found larvae insect , insects and snails. So on headwaters with macrozoobenthos conditions like this describe the condition of clean waters up to be contaminated, so if associated with the value of NVC fish then the headwaters of Yeh Sungi including the contaminated waters category.

This study uses an experimental method using a Completely Randomized Design (CRD) with a single factor, namely handling different fish to organoleptic quality histamine levels consisting of several levels of treatment such as: Handling of tuna at room temperature (control), Handling of mackerel tuna with addition of crushed ice 25% bb which produces a temperature of ±180C, Handling of tuna with the addition of people's salt (10% bb), Handling of mackerel tuna with a mixture of 12.5% ice and 5% salt of the people. The results of the study the effect of handling tuna made histamine levels differ greatly real. The amount of histamine at room temperature averaged 47.78 mg/100g, the amount of histamine in the treatment of crushed ice was 1:4 so that the temperature reached ±18°C averaged 11.30 mg/100g, the amount of histamine in the salt treatment of the people (10% bb) average of 31.00 mg/100g and the amount of histamine in the treatment of 50% mixed treatment B and 50% treatment C averaged 21.45 mg/100g. The effect of handling mackerel tuna makes organoleptic quality that is very significantly different based on appearance. The best appearance in the treatment of crushed ice is 1:4 so that it reaches a temperature of ±18°C of 8.00 with brilliant specifications rather reddish, strong scales, thin mucus. The effect of ear tuna handling results in very different organoleptic qualities based on the eye. The best eye condition in the treatment of 1:4 ice destruction so that the temperature reaches ±18°C at 7.722 with convex specifications, the cornea is somewhat foggy, the pupil is rather dim. The effect of handling mackerel tuna makes organoleptic quality very different based on texture. The texture conditions are best at 1:4 crushed ice treatment so that the temperature reaches ±18°C at 7.83 with elastic specifications. The effect of the handling of tuna produces different organoleptic qualities that are very real based on odor. The analysis showed that the smell was the best in the treatment of 1:4 crushed ice so that the temperature reached ±18°C at 7.778 with the specification of a soft fishy odor. Handling of mackerel tuna should use 1:4 crushed ice to reach a temperature of ±180C because it can maintain histamine levels and organoleptic quality of the fish as a whole.

Plankton is instrumental in the aquatic ecosystem, plankton can be an indicator of fertility and pollution. The quality of a water especially the flooded waters can be determined based on the fluctuations of the plankton population that will affect the trophic levels of the waters. The quality of a water can be measured by knowing the value of the Saprobic Index (SI). The Saprobic index is an index that closely relates to the pollution level. This research aims to determine the level of fertility and pollution levels in the waters of Telaga Tunjung Dam, based on the status of Trophic and Saprobic's structure of Phytoplankton, knowing the relationship (linkage) of trophic status and structure Saprobic phytoplankton with variable water quality in Telaga Tunjung Dam. The methods of study used are descriptive methods of case study. The research was conducted on five stations with four repetitions. Plankton sampling performed actively using plankton net with mesh size 60 μm diameter 25 cm. Based on the results of the status of the trophic waters in Telaga Tunjung Dam is at the head of high Water Fertility (Eutrofik). The pollution level is mild to moderate water with a saprobic index from 0,739 to -0,583. The trophic level relationship and the saprobic structure with the water quality variable show that good water quality affects the abundance of high phytoplankton and mild to moderate pollution levels.

Ikan memiliki kandungan gizi cukup baik terutama dari kandungan protein dan lemaknya. Protein Ikan mudah terserap oleh tubuh manusia, Kandungan lemak Ikan memiliki kandungan Kolesterol yang termasuk dalam golongan HDL. Dengan kelebihan lainnya ikan tidak serta merta mau dinikmati oleh sebagian masyarakat terutama oleh anak-anak. Untuk itu perlu adanya penganekaragaman bentuk olahan ikan sehingga lebih menarik, diantaranya dengan cara membuat Nugget Ikan. Nugget ikan adalah olahan daging ikan yang dicampur dengan sedikit tepung dan telur sebagai bahan dasar. Jenis olahan ini dapat dinikmati dalam jangka panjang karena penyimpanan sebelum dikonsumsi dalam suasana beku. Di desa Sulangai, Kecamatan Petang, Kabupaten Badung memiliki potensi perikanan cukup baik, banyak terdapat kelompok pembudidaya ikan, tetapi kurang aktif. Melihat Potensi yang ada Fakultas Pertanian khususnya Prodi Manajemen Sumber Daya Perairan melakukan pengabdian ke Desa tersebut untuk membantu masyarakat untuk kembali aktif membudidayakan ikan. Ikan yang dibudidaya sangat layak untuk diolah menjadi nugget ikan. Diharapkan dari kegiatan ini dapat memenuhi kebutuhan protein warga dan sebagai pendapatan sampingan bagi ibu-ibu untuk mengisi waktu luangnya. Tujuan dari kegiatan ini adalah untuk memberikan penyuluhan kepada ibu-ibu di desa Sulangai dalam mengelolah ikan menjadi Nugget ikan. Metode yang digunakan dalam Pengabdian tersebut, untuk Nugget Ikan masih bersifat Penyuluhan saja, tidak dilaksanakan Pelatihan karena saat itu Ibu-ibu di Desa Sulangai ada kegiatan lain/Upacara bersamaan dengan waktu Pengabdian. Hasil penyuluhan dan kegiatan ini adalah bapak-bapak kelompok pembudidaya ikan sangat antusias dengan materi ini dan akan mengundang kembali untuk memberikan penyuluhan dan praktik langsung.
