Abstract

The People of Peukan Bada generally work as fishermen. The ships used by the Peukan Bada people are generally wooden material. The capture fisheries sector in the Peukan Bada area is currently still small in scale. This can be seen from the type of fishing gear used by ships operating in the waters of Peukan Bada. The problem is that the shipbuilding industry in Peukan Bada is currently not developing following the challenges faced. So it is necessary to develop a fishing boat yard in the area. The purpose of this research is to find out what meters need to be considered in the development process. The method of collecting data used in this study is the survey method. The survey that will be carried out is by directly observing the conditions and assessing factors related to fishing vessels, the data needed to support this research method is primary data. The primary data were obtained from direct observations of various activities carried out in the shipyard and the results of interviews obtained with workers in the shipyard. The data analysis used is Fishing Bone Analysis the result of this research is that this shipbuilding industry has developments that are still far from capacity, potential, needs, and the need for the development of land parameters, human resources, machinery, materials, methods or ways of working, shipping flows and production capacity.

Abstract

A 28-days trial was conducted in an aquaponics culture system to determine the effect of the different vegetable plants application on the growth performance and survival rate of common carp (Cyprinus carpio). Common carp seeds were obtained from local fish farmers in Aceh Besar District. A total of 360 common carp fingerlings (size 3-5 cm) were used and placed in 12 containers with the capacity of 80 L each. The study used four treatments, namely A (control), B Kale (Ipomoea aquatica), C Lettuce (Lactuca sativa), and D Pakcoy (Brassica rapa subsp. chinensis), with three replications for each treatment. The result showed that different vegetable plants' applications significantly affected (P 0.05) the absolute weight gain, absolute length gain, and survival rate of common carp fingerlings. The highest value obtained was in treatment B (Ipomoea aquatic) with an absolute weight gain of 3.93 ± 0.28 g, absolute length gain of 3.81±0.21 cm, and survival rate of 100±0.0%, while the lowest was in treatment A (control) with an absolute weight gain of 1.21±0.76 g, absolute length gain of 1.70±0.10 cm and survival rate of 91±0.86%. Water quality was also collected in this study and the parameters during rearing were still within the tolerance limits of common carp rearing. Therefore, it can be concluded that the Kale plant, Ipomoea aquatica is the most recommended vegetable plant to be co-cultured with common carp in the aquaponics system.Keywords:AquaponicsCommon CarpVegetable Plants

Abstract

Abstract. A study of analysis of ENSO impact on streamflow of Cisangkuy watershed West Java using Rainfall-Runoff model was done. The study was analyzed by using GR4J model. Daily rainfall and potential evaporation are model initial data. The model was tested for 2 years running by applying least square error method provided by spreadsheet application to reduce the initial value problem. The model showed a good result with Nash-Sutcliffe Efficiency of 70.0. The model was then simulated for 5 years. Monthly streamflow which is model output was then analyzed. The ENSO impact was done by identifying SOI to the variability of rainfall and streamflow. The model result showed that during La-Niña year in 2000, streamflow decreased below normal. The situation remain question that need to be further investigated. During normal year from 2001 to 2004, streamflow was normal. However, during El-Niño year, the decreasing rainfall also have an effect on the decreasing of streamflow in Cisangkuy watershed. The result also showed that the correlation between climate anomaly Nino 3.4 and variability of rainfall and streamflow is significant with correlation coefficient of -0.69 and -0.30, respectively. The regression model was governed and was then utilized to predict the risk analysis in Cisangkuy watershed by using stochastic spreadsheet under Crystal Ball application.

Abstract

Abstract. The snubnose pompano Trachinotus blochii is one of the important commercial fishery commodity in the Indonesian market. The increasing of the market demand has led some efforts to increase the production of this fish. So do the increasing need for green mussels Perna viridis meat. Therefore it is necessary to evaluate the performance of both species in the polyculture system by using raft culture. This study aims to compare the growth performance of snubnose pompano cultivated on a monoculture system and polyculture within green mussels in a raft system. The parameter observed was the differences in the  growth performance of both species and the increase in total weight and survival (SR) of the fish. The results showed that the growth of snubnose pompano did not provide a significant difference in the growth of both cultivating systems whether in monoculture or polyculture system, likewise the shell length and width of the green mussels. We conclude that it is profitable to cultivate both organisms on a polyculture system because it can harvest both green mussels and snubnose pompano together in a period.Keywords: Snubnose pompano, green mussel, monoculture, polyculture, raft, growth Abstrak.

Abstract. The aims of the study were: (1) to test oxygen consumption of Anadara granosa under sub-lethal concentrations of endosulfan, (2) oxygen consumption under sub-lethal concentrations of glifosat and (3) oxygen consumption under mixture of endosulfan and glifosat. Complete randomlizeddesign were applied on this experiment. Initially, the oxygen consumption was standardised against animal’s dry flesh weight. Results showed that dry flesh weight afffected significantly the oxygen consumption.  The relationship between the two variables was formulated as  y = 0.217 + 0.243x.  Based on teh relationship, the oxygen consumption was reported as mg/l/hr of 1g standard animal.  Exposure of blood cockles to various sub-lethal concentrations of pesticides showed that the oxygen consumption rates reduced as the concentrations increased.  For endosulfan, the oxygen consumption rate decreased from (0.5325 ± 0.1556)mg/l/hr at 0.05 ppm to (0.2282 ± 0.1552 ) mg/l/hr at 0.5 ppm.  Increasing glifosat from 50 ppm to 200 ppm reduced the oxygen consumption from (0.3111± 0.1811)to (0.2449 ± 0.2548)mg/l/hr. Accordingly, the oxygen consumption decreased from (0.3376± 0.972)mg/l/hr to (0,2841± 0.2057)mg/l/hr when concentrations of mixture endosulfan + glifosat mixture increased from 0.005 + 50 ppm to 5 + 200 ppm.Keywords: pesticide; endosulfan; glyphosate; Anadara granosa; bioassay; oxygen consumption Abstrak. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi sublethal endosulfan, glifosat, dan secara bersama-sama terhadap konsumsi oksigen kerang darah (Anadara granosa). Metode eksperimental dengan rancangan percobaan Rancangan Acak Lengkap (RAL) diterapkan dalam penelitian ini. Hasil penelitian menunjukan bahwa berat tubuh mempengaruhi laju konsumsi oksigen dengan hubungan y = 0,217+0,243 x, sehingga hasil pengukuran laju konsumsi oksigen dinyatakan sebagai mg/l/jam per 1 gram berat kering kerang standar. Pemaparan terhadap konsentrasi sublethal menunjukkan bahwa laju konsumsi oksigen menurun seiring dengan meningkatnya konsentrasi masing – masing pestisida maupun campurannya.  Untuk endosulfan, laju konsumsi oksigen menurun dari (0,5325± 0,1556) mg/l/jam pada 0,05 ppm menjadi (0,2282 ± 0,1552) mg/l/jam pada 5 ppm.  Untuk glifosat, laju konsumsi oksigen menurun dari (0,3111± 0,1811) mg/l/jam pada 50 ppm menjadi (0,2449 ± 0,2548) pada 200 ppm, sedangkan untuk campuran endosulfan + glifosat, laju konsumsi oksigen menurun dari (0,3376± 0,972)  mg/l/jam pada 0,005 + 50 ppm menjadi (0,2841± 0,2057) mg/l/jam pada 5 + 200 ppm.  Kisaran konsentrasi sublethal ini sangat mempengaruhi konsumsi oksigen kerang darah (Anadara granosa) yaitu laju konsumsi oksigen akan menurun jika konsentrasi endosulfan dan glifosat ditingkatkan. Kata kunci: pestisida; endosulfan; glifosat; Anadara granosa; bioassay; konsumsi oksigen

Abstract

Sea cucumber (Holothuria atra) was used as a reducing and capping agent in the green synthesis process to produce silver nanoparticles (AgNPs). The antioxidant activity of the generated silver nanoparticles was then evaluated. Seacucumber extract was mixed with the AgNO3 solution and homogenized using a magnetic stirrer to create the silver nanoparticles. It was determined that silver nanoparticle production had occurred using a UV-Vis spectrophotometer. Before being examined for antioxidant activity, the generated nanoparticles were first given a characterizing using Fourier Transform Infra Red (FTIR) spectrometers. The maximum uptake was obtained at wavelengths of 440 cm-1 using a UV-Vis spectrophotometer. Functional groups that play a role in the synthesis of nanoparticles were -OH- C=O, and –C-O groups. The free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) with an absorbance maximum (517 nm) was used for antioxidant properties. The antioxidant assay showed that Silver nanoparticles had higher antioxidant activity than sea cucumber extract alone, with an IC50 value of 4 ppm.Keywords:AntioxidantSeacucumberGreen SynthesisSilver NanoparticlesDPPH

Abstract

The mortality of tinfoil barb during transportation is relatively high due to the oxygen consumption rate and excretion of these fishes. Therefore, the use of an appropriate anesthetic drug becomes one of the solutions for solving this transportation problem of tinfoil barb. One of the natural anesthetic drugs with potential to be studied is Chromolaena odorata leaves. The purpose of this study is to evaluate the effectiveness of anesthetic compounds from Chromolaena odorata leaves in the closed transportation of tinfoil barb. The experimental design used was a non-factorial completely randomized design that consisted of four treatments and three replications,then followed by a Tukey test to see if there was a significant difference. The experimental treatments were A (0 ml/L of leaves filtrate), B (80 ml/L of leaves filtrate), C (90 ml/L of leaves filtrate), and D (100 ml/L of leaves filtrate). The observed parameters were fish behavior towards unconscious condition, onset time, immotilization time, survival rate, and water quality. The results showed that the shortest onset time was obtained from treatment D (100 ml/L leaves filtrate), namely 58 minutes towards unconscious condition, then the longest immotilization time was also shown by treatment D, which was 371 minutes. The highest survival rates were also shown by treatment D which were 94,33% during transportation and 76,33% during culture. The water quality parameters during the experiment were in an optimum condition of tinfoil barb. Keywords:AnestheticChromolaenaodorataTransportationTinfoil barb
