Permasalahan yang dihadapi pembudidaya ikan dengan sistem intensif adalah meningkatnya limbah yang terakumulasi pada air dan sedimen. Limbah budidaya ikan pada umumnya berupa padatan dan nutrien terlarut pada air terutama nitrogen dan fosfor. Tujuan penelitian ini adalah mengkaji distribusi nitrogen total dan fosfor total pada budidaya ikan gabus secara intensif yang diberi eceng gondok Eichhornia crassipes dan probiotik (Pseudomonas aeruginosa dan Achromobacter insuavis). Penelitian dirancang menggunakan rancangan acak lengkap dengan perlakuan pemberian kombinasi eceng gondok dan probiotik (A), pemberian eceng gondok (B), dan pemberian probiotik (C), masing-masing perlakuan diulang tiga kali. Benih ikan gabus yang digunakan berukuran panjang 14,74 ± 0,01 cm dan bobot 25,53 ± 0,09 g dengan padat tebar 175 ekor/kolam (50 ekor/m3). Selama 90 hari masa pemeliharaan, ikan gabus diberi pakan berupa pelet dengan kandungan protein sekitar 30%. Jumlah pemberian pakan 5% dari biomassa dengan frekuensi pemberian empat kali dalam sehari (pagi, siang, sore, dan malam). Hasil penelitian menunjukkan nitrogen dan fosfor pada budidaya ikan gabus terdistribusi pada eceng gondok, sedimen, air, dan ikan. Eceng gondok menyerap nitrogen dan fosfor paling tinggi (P<0,05) dibandingkan air, ikan, dan sedimen. Laju pertumbuhan spesifik bobot (4,37 ± 0,01%/hari) dan biomassa (1,88 ± 0,01 g) ikan gabus tertinggi dicapai pada pemberian kombinasi eceng gondok dan probiotik. Hasil ini dapat dijadikan landasan untuk pengelolaan limbah nitrogen dan fosfor pada budidaya ikan gabus secara intensif.One of the problems in intensive aquaculture system is the the accumulation of waste in the water and sediment. Aquaculture wastes are discharged into the water in form of solids and dissolved nutrients which mostly consisted of nitrogen and phosphorus. The purpose of this study was to study the dynamics of total nitrogen and phosphorus in an intensive aquaculture media supplied with water hyacinth and probiotics (Pseudomonas aeruginosa and Achromobacter insuavis). The study was designed using a completely randomized design with treatment combinations of water hyacinth with probiotic (A), water hyacinth (B), and probiotic (C). Each treatment consisted of three replications. The seeds of snakehead used had body length of 14.74 ± 0.01 cm and weight 25.53 ± 0.09 g, stocked in ponds with stocking density of 175 individuals/pond (50 individuals/m3). During 90 days of rearing, the fish were fed with pellet with protein content of 30%. The amount of feeding was 5% of the biomass with feeding frequency of four times a day (morning, afternoon, evening, and night). The results showed that the produced nitrogen and phosphorus in the snakehead cultivation were distributed to water hyacinth, sediment, water, and fish. Water hyacinth absorbed most of the nitrogen and phosphorus compared to water, fish, and sediment. Higher specific growth rate (4.37 ± 0.01%/day) and biomass (1.88 ± 0.01 g) of snakehead were achieved in combination of water hyacinth and probiotic treatment. These results can be used as a basis for the management of nitrogen and phosphorus wastes in an intensive fish farming.

This paper elucidates the phytoremediation potential of water hyacinth (Eichhornia crassipes [Mart.] Solms) for TN and TP rich industrial wastewaters determined for 15 weeks under different set-ups of 2-fold (56 TN mg/l and 15.4 TP mg/l), 1-fold, 1/2-fold, 1/4-fold and 1/8-fold and a control with no nutrients in duplicate. A mass balance was conducted to evaluate the phytoremediation efficiencies and to identify the key mechanisms of nutrient removal from the wastewaters. Our results manifested that water hyacinth is a promising candidate for a batch removal of TN and TP from wastewaters. 100% removal of both TN and TP was observed at the end of the 9th week in all the set-ups mainly due to assimilation and the period between 6Ð9 weeks became the optimum period after which complete harvesting is recommended. Plants having an age of 6 weeks are ideal to commence the free-floating wetland and 21 days hydraulic retention time (HRT) is recommended for optimum removal of TN and TP. Assimilation and denitrification were the key mechanisms of TN removal while assimilation and sorption became the prominent mechanisms in the removal of TP from wastewaters.

EFFECT OF RAINFALL ON  IMAZAPYR  ACTION IN AQUATIC WEED CONTROL     2 ABSTRACT   The aim of this study was to evaluate the influence of different periods of rainfall that occurred after the application of the imazapyr herbicide on the control efficiency of Pistia stratiotes and Eichhornia crassipes. We studied 10 mm rainfall, applied for 5' at different time periods (0h, 2h, 4h, 6h, 8h, 12h, 24h, not simulated rainfall) after the application of imazapyr formulation Arsenal NA, 250 g ai ha-1 (1.0 L cp ha -1). The experiment had completely randomized design with four replications. Plants were evaluated at 7, 14, 21, 28 and 35 days after application (DAA), and the results submitted to analysis of variance by F test and treatment means compared by Tukey's test (p <0. 05). The occurrence of rainfall up to 6 hours after herbicide application, plants of P. stratiotes, negatively affected its efficiency and control; rainfall intervals over 8 hours had no effect in control. The occurrence of rainfall at all time intervals  did not affect the control of E. crassipes plants.  KEYWORDS: water hyacinth, waterlettuce, chemical control, phytotoxicity

Stocking density is an important factor in cultivation, it can save land use, and increase the efficiency of fish farming. The purpose of this research was to determine the different density information on tilapia seeds measuring 2-3 cm as an alternative to using tilapia (O. niloticus) seeds 7-9 cm in size so that they can be developed in Batur Lake. The research was conducted in January - March 2020 in the floating net cages in Trunyan Kintamani village, Bangli, Bali. The research used a completely randomized design method with three treatments and three repetitions. The Tilapia seeds used are 2-3 cm with different stocking densities, 100 ind/m3, 150 ind/m3, and 200 ind/m3. The parameters observed were SGR (Specific Growth Rate), absolute growth, SR (Survival Rate), FCR (Feed Conversion Ratio), and water quality including temperature, DO, pH, TDS. The results of this study indicated that stocking density did not have a significant effect on the growth and survival rate of tilapia seeds, because the temperature was too cold so that the tilapia seeds failed to adapt properly at the beginning of stocking and the physiological conditions of the fish were disturbed so that the fish experienced stress and went to died. Water quality parameters measured include temperature with a range value of 25.86-25.880C, pH with a range value of 9.08-9.13, DO (Dissolved oxygen) with a range value of 7.9-8 mg/L, and TDS (Dissolved solids) with a range value of 1040.25-1041.58 mg/L.

In the present study treatment of wastewater from a large dairy by using water hyacinth was studied in laboratory experiments. Effects of depth of the system, variations in area coverage, prior settling and of daily renewal of the plants was also studied on the efficacy of hyacinth in treating the dairy waste. Water hyacinth (Eichhornia crassipes) was found to grow exceptionally well in the waste (BOD 840.0 mg/L) and brought down the level of BOD from 840.0 to 121.0 mg/L; COD from 1,160.0 to 164.0 mg/L, total suspended solids from 359.0 mg/L to 245.0 mg/L, TDS from 848.0 mg/L to 352.0 mg/L, total nitrogen from 26.6 mg/L to 8.9 mg/L in 4 days. There was very little reduction, however in calcium, sodium and potassium concentration. Results of different experiments showed that systems with shallow depth were more efficient in removing dissolved solids, suspended solids, BOD, COD, nitrogen and phosphorus. Daily renewal of the plants led to slightly better reduction in suspended and dissolved solids, BOD, COD and nitrogen. Water hyacinth coverage was found to have a direct bearing on the treatment efficiency. Pretreatment (settling) of the waste was also found to be favourable as dissolved oxygen content increased rapidly in the experimental sets with pretreatment. Efficiency of removal of various parameters was also good in these sets. From the study it can be concluded that dairy waste can be effectivily treated by water hyacinth. Consideration of above parameters and incorporating them in design factors can greatly increase the efficiency of the system.

The objective of this study was to evaluate the efficiency of application and the efficacy of control of water hyacinth (Eichhornia crassipes) with the use of the diquat herbicide done with two application volumes associated to three droplets classes. Three experiments were conducted; in the first, the application efficiency was evaluated; in the second, the control efficiency and; in the third, the droplet spectrum. They were conducted in a completely randomized design with five, four and six replicates, respectively. The treatments were arranged in a 2 x 3 factorial design, with two application volumes (100 and 200 L ha-1) and three droplets classes (fine, extremely coarse and ultra-coarse) to the first and second experiment and the third comprised two diquat concentrations in spray solution (2 and 4 g i.a. L-1) and three droplets classes (fine, extremely coarse and ultra-coarse). The application efficiency was determined by the coverage by droplets, spray deposition and active ingredient of the herbicide (diquat). The efficacy was measured by the control and the percentage of plants with regrowth at 50 days after application. The spectrum of droplets produced per each nozzle model used to obtain the droplets classes were analyzed. According to the parameters analyzed, using the droplets classes extremely thick and ultra thick can provide greater certainty in the application of diquat in the aquatic environment associated with the deposition of the active and sufficient coverage to control Eichhornia crassipes with both application volumes

<p align="center"><strong>ABSTRACT</strong></p><p class="Paragraf">Snakehead <em>Channa striata</em> is a local specific fish species and has high economic value. Until now the production of snakehead still reelies on the catch of nature because cultivation of snakehead is still underdeveloped. The main constraint in snakehead fish farming is high mortality on snakehead juvenile rearing phase. This study was conducted to determine the best stocking density on snakehead juvenile rearing to achieve optimal production. The treatments used in this study were stocking density of 1 juvenile/L, 2 juveniles/L, and 3 juveniles/L. Snakehead juveniles with a length of 3.41 ± 0.39 cm and weight 0.28 ± 0.07 g, were reared for 42 days in the aquarium sized 40×40×40 cm with a volume of 40 L. Fishes were fed by bloodworms in ad libitum<em> </em>method. The result showed that the treatments did not affect the survival, growth and the ratio of RNA/DNA of snakehead juvenile. Survival of juvenile snakehead ranged 92.5‒94.58% (P&gt;0.05). The result of water quality measurement showed that it was on optimum condition to supporting snakehead growth at 3 juveniles/L stocking density. Furthermore, recirculation can be use to maintenance water quality for optimum condition. Thus, the rearing of snakehead fish juvenile in the recirculation system can use a stocking density of 3 juveniles/L, and the recirculation system could maintain the water quality in good condition.</p><p class="Paragraf"> </p><p>Keywords: growth, recirculation system, snakehead fish, stocking density, survival rate</p><p> </p><p> </p><p align="center"><strong>ABSTRAK </strong></p><p class="Paragraf">Ikan gabus <em>Channa striata</em> merupakan ikan spesifik lokal dan mempunyai nilai ekonomis tinggi.

Cayenne pepper is one of the important economic agricultural commodities and is widely used in the food industry. However, the presence of cayenne pepper seeds is not favored by some people because if consumed can cause digestive disorders. Giberelin is one of the growth regulating substances commonly used to produce seedless fruit growth. This study aims to explore the effect of water hyacinth root extract (Eichhornia crassipes) on plant height, yield and number of cayenne pepper seeds. The study was carried out experimentally using a completely randomized design (CRD) of 4 extract treatments, namely 0 g / l (control), 25 g / l, 50 g / l, and 75 g / l of water hyacinth root extract, each of which was repeated six times. The results of this study indicate that the provision of water hyacinth root extract can increase plant height and yield but reduce the amount of cayenne pepper seeds. The concentration of water hyacinth root extract 75 g / l is the best water hyacinth root extract that can produce an average plant height of 65.67cm, an average yield of 206.50 fruits per plant with an average fruit yield of 170.17 gram per plant and the average number of seeds is 31.17 seeds per cayenne pepper. This study concluded that the root extract of goiter water can reduce the number of seeds and increase plant height and yield of cayenne pepper. Keywords: cayenne pepper, giberelin hormone, water hyacinth and cayenne pepper seeds.
