Abstract

Textile waste consists of insoluble solid particles, salts, dyes and heavy metals and is very difficult to degrade. Chitin derived from shrimp waste has the potential to overcome textile waste in chitin that causes environmental pollution through more economical absorption and easily available raw materials. Factors that improve adsorption performance include pH and temperature. This study was conducted to determine the effect of temperature, pH, and a combination of temperature and pH treatments on the ability of chitin to adsorb textile dye waste. The parameters observed were temperature, pH, combination of temperature and pH, functional groups (FTIR), chitin structure (SEM), and heavy metal test (AAS). Data analysis of statistical test results using two-way Analysis of Variance (ANOVA) followed by Duncan's further test. The ANOVA test results showed that the incubation treatment of temperature, pH, and a combination of different temperature and pH treatments resulted in (p < 0.05). This shows that incubation temperature and pH have an effect (significantly different) on the adsorption of chitin as an adsorbent on dyes. The results of Duncan's test showed that the best chitin adsorption was obtained in temperature incubation at 50°C (A3), incubation at pH 3 (B1), and the best combination adsorption at 50°C and pH 3 of 1,091±0.007a ppm.

The research method used a completely randomized design. The treatments used were a combination of vitamins C and E in supplementation of Artemia sp. as feed: A (vitamin C 57.50 mg/L + vitamin E 28.75 mg/L), B (vitamin C 115 mg/L + vitamin E 57.50 mg/L), C (vitamin C 230 mg/L + vitamin E 115 mg/L), D (vitamin C 460 mg/L + vitamin E 230 mg/L), and E (vitamin C 920 mg/L + vitamin E 460 mg/L), each treatment was repeated 4 times. The main parameters observed were the level of stress resistance (frequency of pectoral fin movement, frequency of operculum movement, frequency of mouth movement) and blood glucose. Data were analyzed using analysis of variance (ANOVA) and further tests were carried out to determine the differences between treatments. The results showed that supplementation of vitamin C and E in Artemia sp. with different dose combinations had a significant effect (P < 0.05) on the frequency of pectoral fin movements, operculum movement frequency, and mouth movement frequency after hypoxia treatment at the 2nd, 4th and 8th hours and blood glucose levels after hypoxia treatment. The best stress resistance level during the study was in treatment C (vitamin C 230 mg/L + vitamin E 115 mg/L), while the lowest was in treatment A (vitamin C 57.50 mg/L + vitamin E 28 mg/L).

Abstract

Plankton plays an important role in shrimp cultivation in ponds, both as an indicator of water quality and as a natural food source for shrimp that are raised. The purpose of this study was to measure the relationship between the dynamics of the plankton community, the concentration of total organic matter, and water salinity with the abundance of plankton in intensive shrimp farming systems. The study was conducted on six units of ponds located in Cirebon district, West Java, Indonesia. The ponds were lined with HDPE on each side and plastic mulch at the bottom. Post larvae of shrimp were stocked at an average density of 110 shrimp.m-2 and maintained for 98 days. Water quality samples were collected for daily measurement. Data were analyzed descriptively and then analyzed using Pearson's correlation test and regression. The results of this study showed that during the shrimp rearing period, 65 species of plankton were identified, consisting of Chlorophyta 20%, Cyanophyta 15.38%, Diatoms 26.15%, Euglenophyta 6.15%, Dinoflagellates 4.62%, Protozoa 10.77%, and Ciliates 16.92% with an average density ranging from 7.56x105-19.99x105 cells.mL-1. Chlorella sp. (Chlorophyta) and Oscillatoria sp. (Cyanophyta) were found to be the dominating species in all ponds. Total phytoplankton density tended to be higher during the first 54 days of culture. The results of the correlation and regression tests showed that the composition of plankton, the concentration of total organic matter, and the salinity of the water affected the abundance of plankton in the pond.

Abstract

The purpose of this study was to investigate the water quality and phytoplankton abundance in Lake Toba to determine its trophic status. This research was conducted from January to March 2024 at four stations in Lake Toba. Water samples were taken using a UWITEC water sampler and a plankton net and brought to the laboratory for analysis. The study measured physical and chemical water quality and phytoplankton abundance. The results showed a brightness ranging between 5.8 and 6.3 meters, chlorophyll-a content <10 µg/L, total nitrogen <750 µg/L, and phosphorus ranging from 20 µg/L to 30 µg/L. Based on these parameters, the nutrient quality of Lake Toba was classified as mesotrophic. Phytoplankton abundance ranged from 22,514 to 33,475 individuals/L, with 33 genera identified across nine classes: Bacillariophyceae, Chlorophyceae, Cyanophyceae, Coscinodiscophyceae, Dinophyceae, Euglenida, Fragilariophyceae, Mediophyceae, and Zygnemophyceae. The diversity index (H') was 2.631 - 2.723, the uniformity index (E) was 0.828 - 0.872, and the percentage of blue-green algae was 14.75 - 20.85. Zygnemophyceae was the most dominant phytoplankton class, with Staurastrum sp. being the most prevalent species. In conclusion, Lake Toba's waters are categorized as mesotrophic based on the chemical parameters and as eutrophic based on phytoplankton abundance, indicating potential nutrient enrichment issues that warrant further investigation.

Abstract

Sumenep Regency is one of the contributors to seaweed production in Indonesia and is classified as a Minapolitan location. One of the seaweed producing districts is Aeng Dake Village, Bluto District. The problem that arises is that there is no food safety system. This results in the product not being able to compete with other products that already implement food safety. So if it enters a wider market, both national and international, the product will experience rejection. This activity aims to apply appropriate technology in implementing sanitation and hygiene to reduce contaminants so that consumers will feel safe regarding the products produced. Community service is carried out through packaging design training activities and creating online marketing media via websites and social media. Namely by providing workshops packaged online using the zoom application (due to the corona pandemic) including material, discussions and simulations of implementing sanitation. Partners still produce processed products on a small scale and are not yet standardized in the field of food safety. This problem results in the product not being able to compete with other products that already implement food safety. Food safety system problems, namely sanitation and hygiene, can be solved by providing training on the concept of sanitation and hygiene, including theory and practical application in the production process flow. The problem of determining shelf life can be solved by training in determining shelf life including theory and practice that can predict product shelf life. It is hoped that the direct practice given to the processing group will provide skills in analyzing and determining the shelf life of products independently.

Abstract

ABSTRAKSenyawa metabolit sekunder merupakan senyawa yang diproduksi suatu makhluk hidup untuk mempertahankan kelangsungan hidup, sebagai bentuk upaya mempertahankan diri dari predator alaminya. Ikan buntal adalah satu organisme laut yang memiliki potensi dalam menghasilkan metabolit sekunder. Tujuan dari penelitian ini untuk menganalisis perbandingan larutan eluen dan fraksi yang optimal untuk menentukan senyawa metabolit sekunder flavonoid pada daging ikan buntal Arothron manilensis. Metode penelitian dilakukan menggunakan metode Skrining Fitokimia dan Kromatografi Lapis Tipis (KLT) untuk mendeteksi senyawa metabolit sekunder. Hasil penelitian menunjukkan bahwa penentuan eluen, kepolaran eluen maupun pereaksi yang digunakan sangat memengaruhi nampaknya profil senyawa metabolit sekunder. Pada fraksi etil asetat senyawa metabolit sekunder flavonoid terlihat paling kuat sedangkan pada fraksi n-hexana senyawa flavonoid terlihat lemah. Kandungan senyawa metabolit sekunder pada ikan buntal Arothron manilensis mengandung komponen senyawa flavonoid. Kandungan senyawa metabolit sekunder flavonoid pada ikan buntal A. manilensis menunjukkan nilai Rf 0.5-0.975 yang memiliki potensi sebagai antioksidan. Diperlukan kembali pengujian High Performance Liquid Chromatography (HPLC), untuk memisahkan molekul senyawa metabolit sekunder dalam waktu minimum.Kata Kunci: Arothron manilensis, Flavonoid, KLT, Skrining Fitokimia.ABSTRACTSecondary metabolites are compounds that are produced by living things to maintain life, as a form of effort to defend themselves from natural predators. Pufferfish are the only marine organisms that have the potential to produce secondary metabolites. The purpose of this research is to analyze the comparisonof eluent solutions and optimal fractions to determine the secondary metabolite compounds of flavonoids in the flesh of the pufferfish Arothron manilensis. The research method was carried out using Phytochemical Screening and Thin Layer Chromatography (TLC) methods to detect secondary metabolites. Research results showed that the determination of the eluent, the polarity of the eluent, and the reagents used greatly affect the appearance of the secondary metabolite compound profile. In the ethyl acetate fraction, the secondary metabolite flavonoid compound is the most prominent, while in the n-hexane fraction, the flavonoid compounds are not visible. The content of secondary metabolites in puffer fish (Arothron manilensis) contains flavonoid compounds. The content of flavonoid secondary metabolites in puffer fish A. manilensis showed an Rf value of 0.5-0.975 which has potential as an antioxidant. High Performance Liquid Chromatography (HPLC) testing is needed again, to separate the secondary metabolite compound molecules in a minimum time.Keywords: Arothron manilensis, Flavonoids, Phytochemical Screening, TLC
