Abstract Gurami having economic values of. Have abundance, namely able in waters with its oxygen relatively low. Belong to the species of carnivorous herbs herbivora. Unprofitableness is eat feed derived from herbs with content nutrition relatively low compared to animals, so it impact on its growth slow, easly diseases, easly stress, hard eat and SR low. The purpose of this research isto know the addition of enzyme lignosellulase in artificialfeedincreased growth and increased survival rate seed gourami. Method research used is experimental with delightful random complete (RAL) with five treatment and four deuterenomy. The treatment used were : control (A), enzyme 550ml (B), enzyme 600ml (C), enzyme 650ml (D), and enzyme 750ml(E). The main parameters measured were growth rate, and survival rate. The supporting parameters observedwas water quality. Data analysis used analysis of variance (ANOVA) to know the effect of the treatments.To know the difference among treatments used Duncan’s Multiple Range Test (DMRT). The result showed that the provision of enzymes give a real power (p<0.01) against growth rate daily and growth long absolute gourami (Osphronemus gouramy) To survival rate and feed conversion ratio gourami give impact which is not dissimilar real. Growth best on treatment E (0.0214), then successive followed by treatment D (0.0174), C (0.015), B (0.0142) and A (0.0128). Conversion ratio feed on all treatment e 10,415, that is, e then successive followed by treatment d (12,915), c (14,3975), b (15,6375) and a (17,5325). Survival rate obtained 100%. Water quality media maintenance gourami is temperature 26ºC - 29ºC, pH 7 – 8, oxygen dissolved 3.5 – 5 mg/l and ammonia 0.004 – 0.005 mg/l.

The aim of the study is to determine the effect of the feed type (Daphnia pulex-based feed and Dajana nano gran brand) on the water quality (presence of microorganisms and suspended solids) and on the growth and survival of Macrobrachium rosenbergii shrimp larvae. The study implementation plan involved 4 groups of shrimps placed under the same conditions, which were evaluated for 14 weeks through periodic observations and biometrics. The data obtained recorded significant differences between the groups where the best growth and survival results were obtained in organisms that received Dajana nano gran feed, regardless of water quality. In addition, the values of protein in shrimp meat up to 45% and different amounts of fatty acids were obtained. It was determined that the Daphnia pulex-based feed showed lower results in the growth rate and survival rate of Macrobrachium rosenbergii shrimp.

The operation and development of the harbour is closely related to pollutant sources in the waters, especially the waters of the Belawan Harbour in Medan. This study aims to assess the status of water quality and determine the index of pollution in the waters. The data used in this study are water quality data from the Medan Harbour's environmental management monitoring and reharbouring book in 4 (four) years during 2015 to 2018. Methods for determining the level of water quality status using the STORET method (Water Quality Data Retention and Retrieval System) and compared to the quality standards of Environmental Decree from Republic Indonesia Number 51 of 2004. Based on the analysis of the testing of 14 seawater sampling points around the waters of harbour, results of measurements of seawater quality in physics, chemistry and biology were varied. The level of pollution of the waters of Belawan Harbour shows the results of analysis that the waters of the Belawan Harbour are in the moderate polluting class with a value of -12 to -19, while 1 (one) station is in the light polluted class with a value of -10.

Penelitian dilaksanakan pada bulan Oktober hingga November 2014 diLaboratorium Hatchery dan Teknologi Program Studi Budidaya Perairan Fakultas Pertanian Universitas Malikussaleh Aceh Utara. Ikan diberi perlakuan dengan konsentrasi deterjen yang berbeda, perlakuan yang diberikan yaitu: perlakuan A (Kontrol), B (deterjen 3 %), C (Konsentrasi deterjen 6 %) dan D (Konsentrasi deterjen 9 %). Pengambilan data dilakukan setiap 7 hari sekali. Adapun rancangan yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan 3 ulangan dan dilanjutkan dengan Uji Beda Nyata Jujur jika terdapat perbedaan. Parameter yang diamati adalah parameter pada laju pertumbuhan, kelangsungan hidup, histologi insang dan efisiensi pakan serta parameter kualitas air (suhu dan pH). Hasil penelitian menunjukkan bahwa ikan nila yang diberi perlakuan konsentrasi deterjen 3 %, 6 %, 9 % berpengaruh terhadap pertumbuhan dan kelangsungan hidup. Perlakuan kontrol menghasilkan nilai, laju pertumbuhan dan efisiensi paling baik, yaitu masing-masing sebesar 2,84 gram, 97,36 %, sedangkan untuk kelangsungan hidup menunjukkan hasil yang terbaik pada perlakuan konsentrasi deterjen 3 % yaitu 100 %. Parameter kualitas air selama penelitian yang diukur antara lain adalah suhu air dengan kisaran 26,6-28,1 ᵒC, dan pH 7,1-7,8. This study aimed to know the effect of surfactant on growth, survival rate and gill histology of tilapia fingerling. It carried out on October to November 2014 at Hatchery and Aquaculture Technology Laboratory, Aquaculture Department Agriculture Faculty Malikussaleh University North Aceh. Experimented fish was given different concentrations of detergent. The treatments were A: control, B (detergent 3%), C (detergent 6%), and D (detergent 9%). Sampling data was done every seven days. Experimental design used was Completely Randomized Design with four treatments and three replications then it was continued by BNT test. Observed parameters were growth rate, survival rate, gill histology, feed efficiency, and water quality (temperature and pH). The result showed that different concentrations of detergent (3%, 6%, 9%) affected on growth and survival rate of tilapia fish. Control gave the best growth rate and feed efficiency which were 2,84 grams and 97,36%. While the highest survival rate was obtained in treatment of detergent 3% which was 100%. The water quality parameters during experiment were temperature ranged 26,6-28,1 ᵒC and pH ranged 7,1-7,8.

Nereis sp. including one of the commodities that have high economic value as well as important commodities in the world of aquaculture. The survival rate of organisms affected by good cultivation management include solid spread, feed quality, water quality, parasites or diseases. High spread solids will have an impact on the decrease in growth rate, feed consumption and survival rate. Therefore, the importance of research on solid spread because it is very closely related to the production and growth speed of cultivated biota. This study was conducted to find out the influence of different scatter solids on the growth and life's smoothness Nereis sp. The research was conducted for 35 days of maintenance using marine worm biota or Nereis sp. The method used is an experimental method using a Complete Randomized Design (RAL) with 5 treatments and 3 repeats namely, Treatment 1: solid spread 50 individuals/m2, Treatment 2: solid spread 100 individuals/m2, Treatment 3: solid spread 150 individuals/m2, Treatment 4: solid spread 200 individuals/m2 and Treatment 5: solid spread 250 individuals/m2. Treatment with solid spread 150 individuals / m2 (P3) gives the best influence in improving the growth and survival of Nereis sp. 0.7838 g and 93.33%.

Sani river is one of the rivers in Pati Regency, provided as the drinking water source by PDAM Tirta Bening. The people’s activities inhabit along the Sani river affect its water quality. The purpose of this study was 1) analyzed the quality of the Sani river water, and 2) evaluated the status of the Sani river water quality. The data used was the 2018 Sani river water quality data obtained from the Environmental Services of Pati Regency. The study's location was represented by selected three monitoring points, i.e., upstream, middle, and downstream areas of the Sani river, such as the Seloromo reservoir, Sidokerto village, and Gilis hamlet. For knowing the river water quality level, it was necessary to compare the river water quality data with the Indonesia Government Regulation (PP) No. 82/2001. The Sani river water quality status was analyzed using the pollution index method according to the Decree of the Minister of Environment No. 115/2003. In conclusion, the Sani river water quality status in such the- study site was classified as slightly polluted and moderate polluted.
