Abstract

AbstrakIkan Patin (Pangasius pangasius) merupakan ikan air tawar yang memiliki nilai ekonomis yang tinggi. Untuk membantu mempercepat pertumbuhan selain dengan menggunakan pellet, ikan patin juga dapat diberikan pakan alami seperti keong mas (Pomacea canaliculata Lamarck), bekicot (Achatina fulica) dan siput air tawar (Lemnaea javanica). Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan jenis keong-keongan yang berbeda terhadap pertumbuhan, kelangsungan hidup, dan konversi pakan. Hasil penelitian menunjukkan bahwa pertumbuhan terbaik terdapat pada perlakuan A, yaitu dengan pemberian keong mas. terbaik kedua pada perlakuan B (pemberian bekicot) dan yang paling rendah pada perlakuan C (pemberian keong air tawar). Selanjutnya untuk tingkat kelangsungan hidup terbaik terdapat pada perlakuan A dan B yaitu sebesar 95.24%, dan yang terendah perlakuan C sebesar 90.47%. Rasio konversi pakan pada perlakuan A yaitu 3.45, sedangkan pada perlakuan C sebesar 7.44.Kata kunci: ikan patin; keong mas; bekicot, siput air tawar; pertumbuhanAbstractPangasius catfish (Pangasius pangasius) is a freshwater fish that has high economic value. To accelerate growth in addition by using pellet, this catfish can also be given live food such as the golden snail (Pomacea canaliculata Lamarck), edible snail (Achatina fulica), and freshwater snail (Lemnaea javanica). This study aims to determine the effect of different types of snail feeding on growth, survival rate, and feed conversion ratio. The results showed that the best growth was found in treatment A, by giving the golden snail, the second best growth in treatment B (by giving edible snail) and the lowest growth in treatment C (by giving freshwater snail). Furthermore, the best survival rate is in treatment A and B which is equal to 95.24%, and the lowest in treatment C (90.47%). Feed conversion ratio in treatment A was 3.45, while in treatment C was 7.44.Keywords: Pangasius catfish; The golden snail; edible snail; freshwater snail; growth

Abstract

The high price of commercial feed causes higher production costs. The problem was experienced by fish farmers, including the groups of pond farmers in East Releut Village, North Aceh. The purpose of this activity is to improve the pond farmer's skills by developing artificial fish feed made from local raw materials using Moringa leaf flour. This service activity uses an educative, participatory, and persuasive method approach. Also, the procedures consist of several stages, that are socialization about artificial fish feed made from local raw materials, socialization about the introduction of various local raw materials that have the potential to be used as feed ingredients, socialization about manufacturing technology fish feed, training in the stages of making fish feed, and marketing training for artificial fish feed made from local raw materials. The socialization and training on the process of artificial feed also motivate pond farmers to produce fish feed made from local raw materials. The participants were very satisfied on the knowledge/information (64,58%), the explanation of knowledge (72,22%), and the whole activity (63,89%), and satisfied on discussion process (58,33%). Participants hoped that developing artificial feed products, could reduce the cost of production

Abstract

The trophic status of Laut Tawar Lake was increasingly leading to an alarming level of degradation. Efforts to anticipate an increase in trophic status require scientific knowledge of the trophic phenomena of the waters empirically. This research examines the trophic status parameters to produce a model of the trophic status of Laut Tawar Lake. The proposed model was a modification of Carlson's Trophic State Index Method. Analysis of the relationship examined the interaction of water clarity (SD) with chlorophyll-a (Chl), Total Suspended Solid, and Total Dissolved Solids, and the interaction of chlorophyll-a with nutrient concentration (TP, TN). Data were analyzed descriptively quantitatively, correlation, and regression. The results showed that the waters of Laut Tawar Lake contain phosphate (TP) 34 µg/L, Total Nitrogen 687 µg/L, chlorophyll-a 10 µg/L, Total Suspended Solid 47 mg/L, Total Dissolved Solid 84 mg/L, and water clarity 4.0 m. The regression test showed that the abundance of phytoplankton (Chl) was affected by nutrient phosphate with the empirical model equation Chl = 0.565 TP – 9.161. Nitrogen nutrients did not partially affect the concentration of chlorophyll-a in the waters of Laut Tawar Lake. Water clarity is influenced by chlorophyll-a and TSS, where TDS has no effect partially. The empirical model obtained is Ln SD = 1.757 – 0.013 Chl – 0.008 TSS. Modification of Carlson's TSI by substituting the two equations obtained the equation TSIdlt = 13.46 + 8.08 ln TP + 0.04 TP + 0.04 TSS. This model simulation gives an estimation rate of 91.06%.

Abstract

Floating net cage activities can cause  water quality to decrease. The feed remains and the metabolism of the fish  from these activities produces nitrogen and phosphorus .  The objective of this study  is to obtain the calculation model and the amount of phosphorus released into the waters of Laut Tawar Lake  as a result of floating  cage activities. The resulting  formula  was Pw = (F x [P]p) – ((It – Io) x [P]i), where their variables were given feed (F), phosphorus concentration of feed ([P]p), the final weight of fish (It), the initial weight of fish (Io), and phosphorus concentration in fishes ([P]i). It can be used to predict the increase in phosphorus waste based on the increase in floating net cage area. The weight of tilapia increases exponentially with the  day of cultivation in the equation Y = 12.70e0.02x and the goldfish followed the formula  Y = 2.28e0.03x. Phosphorus in tilapia varies  from 1.58% to 2.23% with an average of 1.97%. Goldfish contain  1.19 - 2.02% phosphorus, with an average of 1.52%. Goldfish  growth  was not optimal due to inadequate feeding,   so  without excessive feeding and did not generate  phosphorus waste. The cultivation of  tilapia releases  0.09 Kg P/m2 of phosphorus waste from floating cages .

Abstract

Phytoplankton blooms in the lake cause ecological, economic, health, energy, and aesthetic losses. It reduces water quality and biota diversity, creates toxins in the waters, and changes the structures and functions of the ecosystem. The essential nutrients for the growth of phytoplankton are nitrogen and phosphorus. Controlling phytoplankton growth can be managed by controlling the limiting nutrient input. This study aims to identify the limiting nutrient, analyze variations in TN:TP ratio spatially and temporally, and model TN:TP ratio and chlorophyll-a relationship. This study used secondary data from previous studies, namely TN, TP, and chlorophyll-a observed monthly in seven stations purposively during a year. Rainfall data was also obtained from the previous study. Limiting nutrients were determined by Redfield theory, and data were analyzed by Spearman correlation, One-way ANOVA, Kruskal-Wallis, and regression analysis. The results showed phosphorus was a limiting nutrient for phytoplankton growth in Lake Laut Tawar.  TN:TP ratio and chlorophyll-a did not vary spatially, indicating the lake surface waters were evenly mixed. The parameters varied temporally, expressing the influence of hydroclimatological factors, especially rainfall. Rainfall increases nutrient input to the lake, but only rain below 200 mm/month causes an increase in the concentration of nutrients in the lake. The rainfall above 200 mm/month increases lake water volume significantly, thereby reducing nutrient concentrations. TN:TP ratio and chlorophyll-a related negatively and formed a non-linear relationship with an empirical model Chlorophyll-a = 2770.285 (TN/TP)-1.871. Eutrophication of Lake Laut Tawar should be anticipated by controlling the anthropogenic phosphorus input.Keywords:AnthropogenicChlorophyll-aEutrophication,Limiting nutrientRainfall
