Abstract This study was aimed to investigate the phytoremediation capacity and mechanism of Pb by Kiapu plants (Pistia stratiotes) based on the mass balance analysis. This study used 2 treatments, Pb exposure at 10 and 20 ppm. The phytoremediation capacity of Kiapu plants was represented by the absorption/adsorption rate of Pb by the plants during 20 days of cultivation. The mechanism of Pb phytoremediation by Kiapu plants was estimated in mass balance analysis (the mass of Pb in leaves and roots). The value of Pb mass accumulation (in leaves and roots) was used as the basis of phytoremediation mechanism determination. The results showed that Kiapu plants could absorp/adsorp Pb from the water up to 0,71% in leaves and 0,79% in roots out of 50,5 mg in the 10 ppm treatment and that of 0,50% in leaves and 0,52% in roots out of 100,25 mg in the 20 ppm treatment. These result showed that the highest absorption/adsorption was in the root of the plants indicating a rhyzofiltration mechanism during the phytoremediation process. The water quality was not effected by phytoremediation using Kiapu plants. Keywords: Phytoremediation, capacity, mechanism, Kiapu (Pistia stratiotes), mass balance

The study aimed to determine the tourism suitability index and carrying capacity of Red Island Beach. The study was carried out using descriptive method. The study used purposive sampling to determine the tourism suitability index, while the data used for determination of tourism carying capacity was collected directly using QGIS software. The data was colledted from 3 stations along the Red Island Beach, and the distance of each station was 1000 m. The distance of sampling from the beach was 10 m, and performed in triplicate. Parameters measured in this study were: water depth, beach type, beach width, substrate type, water current, slope, water sharpness, land cover, dangerous biota, and freshwater availability. The results showed that the value of the tourism suitability index from 3 stations was categorized into S1 (Very Suitable) (IKW> 80%). The result indicates that the beach of Red Island Banyuwangi can support the development of recreational beach activities. As for the value of the support of the area divided into 2 categories, for the tourism category of recreational beaches obtained the value of carrying capacity of 1,500 people/day, swimming category obtained the value of the support of 240 people/day. It could be concluded that carrying capacity of Red Island Beach is categorized as under carrying capacity. The visitor should be increased up to 36% to reach a balance tourism visit.

Sanggalangit Village is one of the villages in Gerokgak District, Buleleng Regency with the main potential of anchovy fisheries and several other types of fish. The fishing gear used is dominated by seine net. The purpose of this research is to determine the types of fish that have landed to assist in sustainable fisheries management. This research took time from December 2019 to January 2020. Fish samples were obtained by direct observation in the field. Fish sampling was taken using simple random sampling. The catch of fishermen with seine net fishing gear found 23 species of fish grouped into 8 orders and 16 families. The type of fish wealth index obtained was 2.,07, categorized as a low type of wealth index. The relative abundance of fish species received quite a variety of values ranging from 0,01%-0,15%. The analysis of the relationship between the length and weight of the main catch fish showed that the growth patterns were negative allometric.

Penelitian ini bertujuan untuk mengetahui dosis formalin yang paling optimum sebagai desinfektan dalam media pemeliharaan terhadap kelangsungan hidup dan pertumbuhan larva Lobster Pasir (Panulirus homarus). Penelitian yang dilakukan bersifat eksperimental menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan. Perlakuan S0 (kontrol) dilakukan dengan tanpa penambahan formalin, sedangkan perlakuan S1 (penambahan formalin 10 ppm), S2 (20 ppm), dan S3 (30 ppm). Parameter yang diamati yaitu panjang total, kelangsungan hidup (SR), parasit penyebab penyakit pada larva lobster, dan parameter kualitas air. Data diuji secara statistik menggunakan one way ANOVA dan software SPSS 18. Hasil uji statistik menunjukkan bahwa penggunaan formalin berpengaruh nyata terhadap peluang timbulnya penyakit (p<0,05), tidak berpengaruh nyata terhadap panjang total larva lobster pada perlakuan S1 (p>0,05) namun menurunkan panjang total pada perlakuan S2 dan S3 serta tidak berpengaruh nyata terhadap parameter kualitas air (p>0,05). Kelangsungan hidup (SR) tertinggi yaitu sebesar 56% diperoleh pada perlakuan S1, panjang total tertinggi 1872,22 µm diperoleh pada perlakuan S0. Hal ini mengindikasikan bahwa penambahan formalin berpengaruh positif terhadap kelangsungan hidup (SR) dan panjang total larva lobster pasir (Panulirus homarus) pada dosis optimum 10 ppm (perlakuan S1).

Biofloc technology is used to overcome the increase in organic matter, improve the quality of aquaculture water, and increase production yields. This study aims to determine the growth rate and survival rate of African catfish with different stocking densities in the biofloc system. This study used a completely randomized design (CRD) with 3 treatments and 5 replications. The test animals used African catfish measuring 7-9 cm with a stocking density of A (15 ind/15L), B (20 ind/15L) and C (25 ind/15L). The results showed that the use of a biofloc system in African catfish culture with different stocking densities resulted in no significant difference in growth rate, survival rate (SR) and feed conversion ratio (FCR). The average weight growth value of African catfish in treatment A, B, and C was 14,13 ± 2,26 g, 13,37±0,46 g, and 12,04±0,48 g, respectively. The average length growth in treatments A, B, and C was 6,27±0,54 cm, 6,09±0,31 cm, and 5,69±0,34 cm, respectively. The survival value (SR) of African catfish in treatment A, B, and C was 85,33±5,58%, 83±2,73%, and 82,40±2,19%, respectively. The value of the feed conversion ratio (FCR) in treatment A, B, and C was 0,72±0,08, 0,75±0,06, and 0,79±0,03, respectively. The range of values for the water quality parameters of the culture media is categorized as suitable for the growth of African catfish, resulting in temperature, DO, and pH value of 27,5-30,8°C, 3,9-5,9 mg/L, pH 6,20-6,45, respectively. The content of ammonia is 0,26-0,44 mg/L, nitrite is 0,08-0,18 mg/L and nitrate is 0,18-0,29 mg/L.

The purpose of this study was to determine the effect of giving FF-999 pellets with different doses on growth, feed conversion ratio (FCR), survival rate (SR) and water quality of tilapia seeds. This research was conducted at the Fisheries Laboratory, Faculty of Marine Affairs and Fisheries, Udayana University from January-February 2021. Fish samples tested were tilapia seeds (Oreochromis niloticus) obtained from UD. Mina Karya Jaya, Karangasem, Bali. Feed used in this study was FF-999 pellets. Method used is an experimental using a completely randomized design with 5 treatments and 3 repetitions. Doses of feed given in this study were in treatment A was 1%, treatment B was 2%, treatment C was 3%, treatment D was 4%, and treatment E was 5%. Results of observations for 8 weeks showed the highest absolute length and weight growth was found in treatment E, was 4.50 cm and 4.34 g. Lowest feed conversion ratio was found in treatment C was 0.81. Highest survival rate was found in treatments C and D, was 73.33%. Results of statistical analysis One-Way ANOVAwith Duncan's follow-up test showed different treatments had significant effect on absolute length and absolute weight growth, survival rate tilapia (P<0.05) and had no significant effect on feed conversion ratio tilapia (P>0, 05). Water quality parameters measured include temperature, pH, Dissolved Oxygen (DO), ammonia, nitrate, nitrite, and phosphate in all treatments was still considered feasible for growth and survival of tilapia seeds (O. niloticus).
