Kandungan parameter kualitas suhu, salinitas, pH DO lokasi menunjukan nilai yang masih memenuhi standar baku mutu yang bahwa tidak limbah tambak udang yang dihasilkan. ABSTRACT Pacific white shrimp shrimp cultivation in the coastal waters of Central Bangka is carried out intensively using artificial feed as the main shrimp feed. Problems in intensive cultivation are uneaten feed residues and metabolic wastes in the form of feces and urine which have the potential to cause fertility in aquatic ecosystems. Decomposition of organic matter by microorganisms will produce nitrogen compounds in the form of nitrate and phosphate. They will be absorbed by plants that have the potential to cause blooming algae. This study aims to test and analyze the content of nitrate, phosphate and other water quality parameters as well as the suitability of wastewater generated at the disposal site of pacific white shrimp ponds in Central Bangka Regency. The research locations were TLTA Shrimp Pond (Location 1), ALB Shrimp Pond (Location 2), and SDL Shrimp Pond (Location 3). The research method used quantitative descriptive analysis method. The results showed that the nitrate content at locations 1, 2 and 3 were 0.92±0.18 mg/L, 0.89±0.14 mg/L, and 0.93±0.21 mg/L, respectively, and phosphate content of 0.25±0.09 mg/L, 0.15±0.11 mg/L, and 0.23±0.15 mg/L, respectively. The nitrate and phosphate content still meets the standard quality criteria for pond waste water, but there is potential for eutrophication when they flow into estuary or seas area. Their values are in the range that can cause eutrophication. The content of water quality parameters TSS, BOD, COD, turbidity, temperature, salinity, pH and DO at all location points shows values that still meet quality standards which illustrate that there is no pollution from shrimp pond waste produced.

Small-scale capture fisheries condition is multi gear and multispecies has an impact on increasing the pressure of fish condition. The information related to fisheries resource status is very essential in order to build sustainable fisheries management planning. This study aims to analyze the level of fishing gear productivity, clustering of fishing gear based on the number of catch fish in Prigi, East Java. These study results are expected as sustainable small-scale fisheries management recommendations. This research methods were used the analyzed of diversity by Shannon-Wiener index, catch per unit effort (CPUE) and clustering of fishing gear based on a combination between principal component analysis (PCA) and hierarchical cluster. The results showed that the composition of the catch in each fishing gear was varied. The highest diversity of fish used gillnet as fishing gear. In general, the type of fishing gear with the most catches in AFP Prigi is handline, meanwhile scoop net became the highest CPUE of fishing. Clustering of fishing gear tends to be the same with varying proximity and gillnet fishing gear is a fishing gear that tends not to group with other tools. This study resulted that the clustering of fishing gear tends not to change in the last 10 years, however the correlation between groups are dynamic and this case has an impact on the variations of catch fish and fishing gear productivity.

Jelitik is located in Bangka regency and it categorized as an industrial area based on Regional Regulation, Bangka Regency Number 3 in 2005. The Jelitik river channel and estuary received high sediment input and it become shallower due to anthropogenic activities in upstream, industrial activities and tin mining activities around the area. The potential for nutrient enrichment and increasing river estuary pollution can come from point sources such as industry or non-point sources from the Jelitik industrial area. Based on these problems, the purpose of this study was to analyze the trophic state of the Jelitik river estuary based on the trophic state index (TSI) and analyze the contamination status based on the Storet index method and CCME WQI. Six locations were determined by purposive sampling, while physical, chemical and biological parameters were analyzed in April and August 2021. Based on the location index, the six locations in the Jelitik river estuary area were still good/lightly polluted, while based on the CCME WQI, it was classified as good to fair. The research location can be categorized as oligotrophic based on TSI. The potential of quality and quantity degradation of the Jelitik estuary area requires an integrated effort and an effective and efficient strategy in overcoming the existing problems.

Sungai Babon merupakan salah satu sungai di Semarang, Jawa Tengah yang dimanfaatkan untuk berbagai aktivitas manusia sehingga berpotensi menghasilkan limbah yang akan mencemari perairan. Perubahan kualitas air akibat pencemaran akan mempengaruhi persebaran dan struktur komunitas fitoplankton. Diatom (Bacillariophyceae) adalah salah satu kelompok fitoplankton yang tersebar luas di perairan karena memiliki daya adaptasi yang tinggi. Tujuan dari penelitian ini adalah mengetahui kondisi kualitas air dan struktur komunitas diatom (Bacillariophyceae) di Sungai Babon. Penelitian ini dilakukan di 5 stasiun yang tersebar dari hulu hingga hilir Sungai Babon pada bulan April dan Mei 2021. Variabel kualitas air yang diukur meliputi suhu, kecerahan perairan, pH, oksigen terlarut (DO), nitrat, dan fosfat. Hasil penelitian ini menunjukkan parameter kualitas air Sungai Babon masih sesuai dengan baku mutu PP RI No. 22 Tahun 2021 Kelas II tentang Penyelenggaraan Perlindungan dan Pengelolaan Lingkungan Hidup, kecuali kadar oksigen terlarut di Stasiun 5. Diatom (Bacillariophyceae) yang ditemukan di Sungai Babon berjumlah 17 genera. Diatom yang paling banyak ditemukan adalah Navicula, diikuti Synedra, Surirella, dan Melosira. Navicula adalah genus diatom yang ditemukan di semua stasiun penelitian dan memiliki kelimpahan tertinggi dengan persentase kelimpahan berkisar antara 13,82-52,83% dari kelimpahan total setiap stasiun. Diatom memiliki indeks keanekaragaman yang rendah, keseragaman tinggi (merata), dan dominansi rendah. Babon River is one of the rivers in Central Java that is used for various human activities so it has the potential to produce waste that will pollute the waters. Changes in water quality will affect the distribution and structure of the phytoplankton community. Diatoms (Bacillariophyceae) are a group of phytoplankton that is widely distributed in waters because they have high adaptability. The purpose of this study was to determine the condition of water quality and community structure of diatoms (Bacillariophyceae) in the Babon River. This research was conducted at 5 stations spread from upstream to downstream of the Babon River in April and May 2021. The water quality variables measured included temperature, water transparency, pH, dissolved oxygen, nitrate, and phosphate. The results showed that the water quality parameters of the Babon River are still following the quality standards of PP RI No. 22 of 2021 Class II, except for dissolved oxygen levels at Station 5. Diatoms (Bacillariophyceae) found in Babon River are 17 genera. The most common genus was Navicula, Synedra, Surirella, and Melosira. Navicula is a genus of phytoplankton found in all stations and has the highest abundance with a percentage from 13.82 to 52.83% of the total abundance of each station. Diatoms have a low diversity index, high similarity, and low dominance.

Sambal is a side dish, one of the variants of which is basic chili sauce with additional ingredients of various types of fish such as bete-bete fish (Leiognathus sp). The purpose of this study was to examine the proximate composition and sensory properties (hedonic and description) and to determine the shelf life of bete-bete fish sauce (SIB) using the Accelerated Shelf Life Testing (ASLT) method using the parameters of the total content of bacteria and molds in the chili sauce. The treatments included the use of fish (%) and basic chili sauce (%) with a ratio of 50:50 (SIB1), 40:60 (SIB2), and 30:70 (SIB3). The results showed that the highest proximate composition of SIB was protein and fat with a range of 35.23+1.56 - 42.32±0.45% and 21.14±0.13 - 32.53±1.75, respectively. %. The most desirable sambal (sensory hedonic test) is SIB3, which has the characteristics of appearance: red color typical of fish sauce, slightly bright, brilliant, homogeneous, clean and attractive, aroma: typical of fish sauce is strong, fragrant and fresh, and the consistency is not thick with taste. which is delicious, typical of fish sauce, spicy and somewhat savory. Based on the total parameters of bacteria and molds, it is suspected that the bete-bete fish sauce (SIB3) has a shelf life of 22, 19 and 18 days, respectively, at storage temperatures of 20, 25 and 27 °C.

Cryoprotectant plays a role in saving biological material during cryopreservation. Dimethyl sulfoxide (DMSO) as a cryoprotectant has the ability to quickly penetrate into the cell at equilibration and leave the cell at thawing procedure. This study aims to determine the best dose of DSMO in honey extender to the characteristics of the featherback Fish spermatozoa cells in the cryopreservation process. This research was conducted at the Laboratory of Balai Pembibitan dan Hijauan Pakan Ternak (BPHPT) Sembawa from March to November 2020. The test fish were obtained from catches from nature, then reared for 4 months to get the maximum level of gonad maturity. Sperm cell retrieval is carried out by stripping, the stripping process is carried out by massaging the belly of the fish in a circular manner. The results showed that at storage time of 28 days, P3 gave the best results on motility (score 3), and the viability value was 48,93%, higher than Control, P1 and P2. In addition, the treatment did not show any abnormalities that occurred in the featherback fish sperm.
低温保护剂在生物材料的低温保存中起着重要的保存作用。二甲基亚砜(DMSO)作为一种低温保护剂，具有在平衡状态下快速渗透到细胞内，并在解冻过程中离开细胞的能力。本研究旨在确定蜂蜜增稠剂中DSMO对羽背鱼精子细胞低温保存特性的最佳剂量。这项研究于2020年3月至11月在Balai Pembibitan dan Hijauan Pakan Ternak (BPHPT) Sembawa实验室进行。试验鱼从自然捕捞中获得，然后饲养4个月，以达到性腺成熟的最高水平。精子细胞的提取是通过剥离来进行的，剥离过程是通过以圆形的方式按摩鱼的腹部来进行的。结果表明，贮藏28 d时，P3的活力表现最好(3分)，其活力值分别为48.93%，高于对照、P1和P2。此外，治疗没有显示任何异常发生在羽背鱼精子。

The COVID-19 pandemic is causing a significant public health crisis. The elderly who are old and usually have a weak immune system can be fatal if exposed to the Covid-19 virus. One of the efforts that can be done so that the elderly are prevented from exposure to COVID-19 is by protecting them from within the body by having a strong immune system—increasing immunity in the elderly by consuming foods with high antioxidant compounds, including the algae Halimeda sp and Sambiloto. This study aims to determine the characteristics and potency of Halimeda sp. and bitter combination compound to increase body immunity using in silico analysis. The best total phenol and IC50 values were obtained from the 1:1 weight ratio treatment between the crude extract of Halimeda sp algae and the crude extract of bitter leaf. GC-MS analysis with screening quality above 85% obtained 3 (three) compounds, namely 2-Butoxyethanol (74.12%), gamma-Butyrolactone (23.72%), and Phenol (2.15%). These compounds have potential as antioxidants, anti-inflammatory, immunostimulators, and antivirals based on the PASS server. All compounds have good drug-likeness potential, absorption, distribution, metabolism, excretion, and toxicity in the body based on in silico analysis (SwissADME and Pro Tox II). It can be the basis for developing nutraceuticals for the elderly to increase immunity and prevent exposure to Covid-19.

Shrimp paste is a fermented product made of small shrimps with addition of salt that functions as preservative agent, driving the growth of lactid acid bacteria, and improving sensory quality of shrimp paste. The use of different types of salt in processing shrimp paste is able to affect sensory and physicochemical characteristics of shrimp paste. This research aims to determine the effect of different types of salt used toward shrimp paste sensory and physicochemical characteristics. The research was done in experimental laboratories with Completely Randomized Design (CRD) by using different types of salt as the factor (Crushed Salt, Bledug Kuwu Salt and Himalayan Salt) with three replications. The parametric testing done were moisture content, salt, water activity, LAB Total Plate Count (TPC), pH, color and organoleptic. The parametric data was analyzed using Analysis of Variance (ANOVA) and Honestly Significant Difference (HSD), non-parametric data was analyzed with Kruskal-Wallis and Mann-Whitney Tests. Based on the research, moisture content 30.62-31.41%, salt content ranges from 6.84-22.46%, water activity 0.64-0.66, LAB TPC value 1.5 x 106 – 5.3 x 108 , pH 6.28-6.32, oHue Value ranges from 72-83o indicating yellow red color and organoleptic value sequentially for GK, GB and GH are 7.74 <µ< 8.16; 7.48 <µ< 7.85 and 7.79 <µ< 8.12. It can be concluded that himalayan salt treatment showed the significant difference towards salt content, LAB TPC value, redness color, and taste on organoleptic test
