Probiotics are microbes in fermented foods that have beneficial effects on health. Microbes that act as probiotics are lactic acid bacteria (LAB) that can produce metabolites such as lactic acid, hydrogen peroxide, and bacteriocins. This study aimed to obtain lactic acid bacterial isolates from tape and tempeh, and to test the potential of LAB as a probiotic candidate by activity test as an antidiarrhea and its resistance to gastric pH and bile salts. The fermentation products used as a source of LAB isolates are tempeh sumber mas merk, and yellow cassava tape, sari madu merk from Jember. The results of the first stage regarding the isolation of LAB using GYP media showed that there were 2 LAB isolates (TaJ.14 and TaJ.15) from the tape and 4 LAB isolates (TeJ.18, TeJ.22, TeJ.24, and TeJ.25) from tempeh. The results of the antidiarrheal test using the disc diffusion method (oxoid) showed that TaJ.14 and TaJ.15 isolates were able to inhibit Bacillus subtilis, Escherichia coli, and Shigella dysentriae, while TeJ.18, TeJ.22, TeJ.24, TeJ.25, and Lactobacillus casei (control) was only able to inhibit B. subtilis and E. coli. The results of LAB resistance to gastric pH showed that the TeJ.25 isolate had the highest percentage of pH 3 and 2.5 resistance (51.13 and 33.03%) compared to other isolates and controls. LAB resistance test results against bile salts (oxgal) showed that the TeJ.22 isolate had the highest percentage of resistance (75.10%) compared to other isolates although was still higher in control (75.99%).

Plant Growth Promoting Bacteria Rhizobacteria (PGPR) is one of the potential bacteria to enhance of Capsicum annuum through inhabitation the growth of pathogenic fungi. This study aimed to characterize PGPR in chili plants (Capsicum annuum). PGPR was isolated from the soil habitat of the red chili plant in Cilegon, Indonesia. Screening was then carried out with the dual culture method on Petri dishes and tested through in vivo method on the red chili plant. The selected bacteria were characterized morphologically, biochemically, and physiologically. The results revealed that there were 14 single isolates of bacteria from the roots of the red chili plants. The five single bacterial isolates, namely Azostobacter, Azospirillum, Pseudomonas, Serratia, and Beijerinckia have good potential as PGPR based on multiple culture screening by producing clear zones and positively effect the growth of chili plants.

The COVID-19 has spread worldwide and become an international pandemic. The promising target for drug discovery of COVID-19 was SARS-CoV-2 Main Protease (Mpro), that has been successfully crystallized along with its inhibitor. The discovery of peptide-based inhibitors may present better options than small molecules for inhibitor SARS-CoV-2 Mpro. Natural compounds have such a wide potential and still few explored, Zizyphus spina-christi is one of the medicinal plants that have many pharmacological activities and contains a peptide compound from alkaloids class, i.e. cyclopeptide alkaloids, that is interesting to explore as SARS-CoV-2 Mpro inhibitor. The compound structure was drawn and optimized using density functional theory 3-21G method. The protein chosen was the high resolution of SARS-CoV-2 MPro receptor (1.45 Å) with PDB ID: 6WNP, in complex with boceprevir. Molecular docking simulation was performed using Autodock4 with 100 numbers of GA run, the validation methods assessed by RMSD calculation. Furthermore, the prediction of pharmacological activity spectra was carried out using the PASS Prediction server. The results showed RMSD value was 1.98 Å, this docking method was valid. The binding energy of all compounds showed better results than the native ligand (Boceprevir). The in silico PASS prediction results indicated that all compounds showed antiviral activity. Some compounds showed protease inhibitory activity, i.e Ambiphibine-H, Franganine, and Mauritine-A, and the highest Pa (Predicted activity) value showed by Mauritine-A compounds. It can be concluded that the cyclopeptide compounds of Zizyphus spina-christi were indicated to have a potential as COVID-19 therapy targeting SARS-CoV-2 Mpro.
新冠肺炎疫情已在全球蔓延,成为国际大流行。SARS-CoV-2主蛋白酶(Mpro)及其抑制剂已成功结晶,有望成为新冠肺炎药物开发的靶点。基于肽的抑制剂的发现可能比小分子抑制剂SARS-CoV-2 Mpro提供更好的选择。天然化合物具有如此广泛的潜力,但开发的还很少,Zizyphus spina-christi是具有许多药理活性的药用植物之一,它含有生物碱类的肽化合物,即环肽生物碱,作为SARS-CoV-2 Mpro抑制剂值得探索。采用密度泛函理论3-21G方法对复合材料结构进行了绘制和优化。选择的蛋白是高分辨率的SARS-CoV-2 MPro受体(1.45 Å), PDB ID: 6WNP,与boceprevir复配。使用Autodock4进行分子对接模拟,运行100次GA,通过RMSD计算评估验证方法。此外,利用PASS预测服务器进行药理学活性谱预测。结果显示RMSD值为1.98 Å,该对接方法是有效的。所有化合物的结合能均优于天然配体(Boceprevir)。结果表明,所有化合物均具有抗病毒活性。一些化合物表现出蛋白酶抑制活性,如Ambiphibine-H、frananganine和Mauritine-A,其中Mauritine-A化合物的Pa(预测活性)值最高。综上所述,spina-christi的环肽化合物具有作为靶向SARS-CoV-2 Mpro的COVID-19治疗药物的潜力。

Common carp (Cyprinus carpio) cultivation is often hampered by a disease attack, one of them is the attack of Edwarsiella tarda. Lactic acid bacteria (LAB) can be used as an alternative to prevent diseases in fish by increasing the body's resistance. This research aimed to determine the most effective isolates of LAB that increase of the resistance of carp fingerlings to the attack of E. tarda bacteria and see which isolates can produce the highest survival. The LAB isolates used were the result of isolation from the gut of carp. This study used a Completely Randomized Design (CRD) consisting of four treatments with three replications. The fish were immersed with different LAB isolates, CcB7, CcB8, and CcB15 in the same density of 108 cells / mm3. Immersion was carried out for 30 minutes with a frequency of seven days. While during the research, two immersions were carried out before the challenge test against E. tarda bacteria. The parameters observed were the number of leukocytes, hematocrit, erythrocyte, differential leukocytes, survival rate, and clinical symptoms that appeared. The results showed that all LAB isolates used in this study could increase the body resistance of carp against the attacks of E. tarda bacteria. The LAB CcB7 isolate was the most effective for enhancing the body resistance of carp fish withthe highest increase level of  leukocyte, erythrocyte, and hematocrit were 18 ± 0.057,7 ± 0,077, and 0.26± 7.31% respectively. After being challenged with E. tarda bacteria producing mild clinical symptoms, the highest increase is in monocyte and neutrophil cells was 20 and 62% respectively, the highest reduction in lymphocytes was – 9%  and the highest survival rate was 80%. 
鲤鱼(Cyprinus carpio)的养殖经常受到疾病侵袭的阻碍,其中之一是迟发爱德华氏菌的侵袭。乳酸菌(LAB)可以作为一种替代品,通过增加身体的抵抗力来预防鱼类疾病。本研究旨在确定提高鲤鱼幼鱼对迟达杆菌抗性的最有效的乳酸菌分离株,并观察哪些分离株的存活率最高。所使用的乳酸菌是从鲤鱼肠道中分离出来的。本研究采用完全随机设计(CRD),包括4个处理,3个重复。用不同的LAB菌株CcB7、CcB8和CcB15以108个细胞/ mm3的相同密度浸泡鱼体。浸泡30分钟,频率为7天。在研究过程中,在对塔达埃希菌进行攻毒试验之前,进行了两次浸泡。观察白细胞数、红细胞比容、红细胞、分化白细胞、生存率、临床症状。结果表明,本研究所分离的乳酸菌均能提高鲤鱼对迟达芽胞杆菌的抗性。乳化酶CcB7分离物对鲤体抵抗力的提高效果最好,白细胞、红细胞和红细胞压积分别提高18±0.057、7±0.077和0.26±7.31%。临床症状较轻的迟发性大肠杆菌攻毒后,单核细胞和中性粒细胞的增幅最高,分别为20%和62%,淋巴细胞的降幅最高,分别为- 9%,存活率最高为80%。

Phytoplankton community plays an important ecological role in the aquatic ecosystems as the primary producers and forms the fundament of the aquatic food chain for supporting the water community. Thus, the phytoplankton community structure is a good indicator of water quality due to its sensitiveness to environmental stresses. Two newly dug ponds in Institut Teknologi Sumatera may give an opportunity to study the early colonizing stages of various freshwater communities including phytoplankton. The study attempted to determine the composition and abundance of phytoplankton. Samples were collected from two ponds (A and C) in the reservoir water of Institut Teknologi Sumatera. The content of Phosphorus (P), Nitrogen (N), and Chlorophyll-a (algae biomass) were determined. Phytoplankton had higher diversity in Pond C than Pond A in the study period, in which a total of seven taxa were found, namely Bacillariophycea, Cyanophyceae, Chlorophyceae, Conjugatophyceae, Dinophyceae, Euglenophyceae, Gymnodiniaceae. The most species abundance of both ponds was Peridinium sp. and Trachelomonas sp. The Pond C had the highest mean value of the Shannon-Wiener diversity index. The Linear mixed-effect model showed that low turbidity will result in high phytoplankton diversity. The finding of this study suggests that higher phytoplankton diversity would achieve a natural carrying capacity, and thus would serves as an indicator of ecosystem health.
浮游植物群落作为初级生产者在水生生态系统中起着重要的生态作用,是支撑水生生物群落的水生食物链的基础。因此,浮游植物群落结构对环境胁迫非常敏感,是反映水质的良好指标。苏门答腊理工学院新挖的两个池塘可能为研究包括浮游植物在内的各种淡水群落的早期定殖阶段提供了机会。这项研究试图确定浮游植物的组成和丰度。从苏门答腊理工大学水库水的A和C两个池塘中采集样本。测定了磷(P)、氮(N)和叶绿素-a(藻类生物量)的含量。C池浮游植物多样性高于A池,共发现硅藻科、藻藻科、绿藻科、共轭藻科、藻藻科、裸藻科、裸子藻科7个类群。两个池塘的物种丰度均以Peridinium sp.和Trachelomonas sp.最高,而池塘C的Shannon-Wiener多样性指数平均值最高。线性混合效应模型表明,浊度越低,浮游植物多样性越高。本研究结果表明,较高的浮游植物多样性将达到自然承载能力,因此可以作为生态系统健康的指标。

According to the Flora of Java, there is only one species of Evolvulus in Java, namely Evolvulus alsinoides. Since then, a second species was reported in 2017 from Universitas Indonesia, Depok, West Java, as an alien naturalized species. Some recent field studies have been conducted to provide updated taxonomic information of the genus on this island. The field observations were carried out in Banten, Jakarta, West Java, Jogjakarta, and East Java from March to December 2019. The herbarium studies were also conducted in Herbarium Bogoriense, Herbarium of Bogor Botanic Gardens, Herbarium Bandungense, and Herbarium of the Department of Biology, Universitas Indonesia. Our study reveals one newly recorded species of Evolvulus in Java already grown in cultivation, namely E. glomeratus Nees & Mart. subsp. grandiflorus (Parodi) Ooststr. Besides that, Evolvulus nummularius is now also reported to occur in other sites of West Java and extended to Central Java. An updated key to Evolvulus in Java, descriptions to both species, photographs, and brief discussions are provided.
根据《爪哇植物志》,爪哇只有一种Evolvulus alsinoides。从那以后,2017年在西爪哇德波的印度尼西亚大学报告了第二个物种,作为外来归化物种。最近进行了一些野外研究,以提供岛上该属的最新分类信息。实地观测于2019年3月至12月在万丹、雅加达、西爪哇、日雅加达和东爪哇进行。植物标本室的研究也在波哥大植物标本室、茂物植物园植物标本室、班敦根斯植物标本室和印度尼西亚大学生物系植物标本室进行。我们的研究揭示了爪哇地区新记录的一种已被人工栽培的Evolvulus,即E. glomeratus Nees & Mart。无性系种群。桔梗(桔梗属)此外,据报道,在西爪哇的其他地点也发现了nummularius Evolvulus,并向中爪哇扩展。提供了爪哇Evolvulus的更新关键,对两个物种的描述,照片和简短的讨论。

Marine ornamental trade has been developing for several years with Indonesia as one of the major exporter countries. Among the popular marine ornamental fish in the local and international markets belong to the family of Chaetodontidae. The existence of this family has been reported from several areas in Indonesia. However, no information is available in terms of their phylogenetic relationships of the fish from the south coast of West Java. The aim of this research was to asses the phylogenetic relationships among ornamental fish members of Chaetodontidae in the South Coast of West Java. Fish samples were collected from two trading sites Ujung Genteng and Taman Manalusu. Collected fish were identified using a previously published study. The evolutionary relationships among species were analyzed statistically through phylogenetic analysis based on maximum parsimony algorithm and Kimura 2- Parameter substitution model as implemented in PAUP 4.0 software. Tree branching pattern supported by 1000 bootstraps pseudo-replicates and out-group comparison. Daschyllus trimaculatus used as outgroup species. Based on the study, Chaetodontidae from the South Coast of West Java formed one monophyletic group compared to Dascylus trimaculatus with Chelmon rostratus was the basal species. All the remaining species were the derived species. There are CI and RI value gained. The consistency index (CI) value of this family is 0.5833, and the retention index (RI) is 0.5082. 
近年来,海洋观赏贸易不断发展,印尼是主要出口国之一。在当地和国际市场上受欢迎的海洋观赏鱼中,有一种是毛齿鱼科。在印度尼西亚的几个地区都报道过这个家族的存在。然而,没有关于它们在西爪哇南海岸的鱼类系统发育关系的信息。本研究旨在探讨西爪哇南海岸齿毛鱼科观赏鱼成员间的系统发育关系。鱼类样本采集于Ujung Genteng和Taman Manalusu两个贸易点。收集到的鱼是根据先前发表的一项研究进行鉴定的。采用PAUP 4.0软件实现的最大简约算法和Kimura 2参数替代模型进行系统发育分析,统计分析物种间的进化关系。由1000个bootstrap、伪复制和群外比较支持的树形分支模式。作为外群种的三角圆尾鼠。研究结果表明,西爪哇南岸毛齿毛齿科与三角毛齿毛齿毛齿形成了一个单系类群,其基础种为弓齿毛齿毛齿。其余种均为衍生种。获得了CI和RI值。该家族的一致性指数(CI)为0.5833,保留指数(RI)为0.5082。

SSR marker is one of the genetic markers widely applied in plant breeding programs. The application of molecular markers in plant breeding is meant to accelerate the selection of cross-progeny. The research aimed to identify the SSR primers polymorphism between the parent and control that linked to Al tolerance and verify the cross-progeny of five crosses. The result gained from 37 SSR primers used in this study showed that only nine primers are polymorphic. These nine polymorphic primers are RM257, RM214, RM247, RM205, RM490, RM262, RM569, RM271, and RM19. The application of polymorphic markers on five cross-progeny which have shown the same band pattern as the parents and tolerant control on the use of 9 SSR primers recorded as follows: RM257 2 lines, RM214 5 lines, RM247 5 lines, RM205 lines, RM490 13 lines, RM262 5 lines, RM569 7 lines, RM271 4 lines, and RM19 6 lines. The selected SSR primers linked to Al tolerance in this research can be used as a reference for molecular breeding strategies to develop new Al tolerance rice varieties in dryland conditions.

Barred loach is wild fish in which there is no information related to its enzymatic digestive capacity yet. Therefore research on this subject needs to be conducted.  The spectrophotometry method was used to study protease, lipase, and amylase activities in barred loach. The study used 89 fish with an average weight of 3.61 ± 0.26g, and 1.68 ± 0.21g.  The results showed that pH 7.0 was the highest protease activity. Similarly, lipase activity found  between pH 7.0 and pH 8.1. Still, the amylase activity found to be high at pH 8.1. Protease activity also found to be high in the posterior intestine than in the hepato-pancreas and anterior intestine. Lipase and amylase activities did not found differences between hepato-pancreas, anterior intestine, and posterior intestine. In conclusion, the protease, lipase, and amylase activities of barred loach found along the gastrointestinal tract in both large and small fish, which shows that barred loach can digest protein, fat, and carbohydrates in diets better.
泥鳅是一种野生鱼类,目前还没有关于其酶消化能力的信息。因此,需要对这一课题进行研究。采用分光光度法测定了泥鳅体内蛋白酶、脂肪酶和淀粉酶的活性。该研究使用了89条鱼,平均体重分别为3.61±0.26g和1.68±0.21g。结果表明,pH 7.0时蛋白酶活性最高。同样,脂肪酶活性在pH 7.0和pH 8.1之间发现。尽管如此,在pH为8.1时,淀粉酶活性仍然很高。蛋白酶活性在后肠也比肝胰腺和前肠高。肝胰、前肠和后肠间脂肪酶和淀粉酶活性无差异。综上所述,斑纹泥鳅的蛋白酶、脂肪酶和淀粉酶活性在大鱼和小鱼的胃肠道中均有发现,说明斑纹泥鳅对饲料中的蛋白质、脂肪和碳水化合物的消化能力较好。
