Kijing Taiwan (Anodonta woodiana) is found in water with muddy substrate. Kijing Taiwan lives in bottom waters and is relatively settled. Kijing Taiwan is a filter feeder organism that can filter water and is able to survive in polluted environment, so it can be used as a bio-indicator of a water body. The study was conducted in the Public Hatchery Unit (UPR) Sumber Mina Lestari. Profile hemocytes in Taiwan Kijing influenced by environment pollution inducer among others. Hemocytes were observed consisting of Total Haemocyte Count (THC) and Differential Haemocyte Count (DHC). The results show that the profile of hemocytes (THC and DHC) of Kijing Taiwan is not polluted. Results from aquaculture pond water quality measurements indicate that the indicators of the water quality i.e. temperature, pH, dissolved oxygen, and ammonia are still within normal limits. However, in TOM test, BOD and soil organic matter has exceeded the normal limits. The existence of organic matter became the medium of life for Kijing Taiwan, due to its role as a biofilter among other organic materials. Keywords: Hemocytes Profile, Kijing Taiwan, Water Quality.

The food processing by heating can increase the formation of AGEs (Advanced Glycation End Products). AGEs are compounds that formed from a non-enzymatic continuous glycation reaction between proteins and sugar residues. The CML (N-carboxymethyl-lysine) is used as a marker for AGEs cause most commonly found in vivo. The bond of AGEs and RAGE (receptor for AGEs) induce various signaling pathways that trigger inflammation and increase oxidative stress. The AGE and RAGE interaction activate the transcription factor of NF- κβ. NF- κβactivates gene transcription to release proinflammatory cytokines such as TNF-α. Anthocyanins are compounds that can prevent the formation of AGEs and muffle the adverse effects of AGEs. Rosella contains anthocyanin such as: delphinidin-3-O-glucoside, delphinidin-3-O-sambubioside, and cyanidin-3-O-sambubioside. This study is to determine whether the daily intake of Rosella extract can reduce the levels of n-carboxymethyl-lysine in serum, expression of NF-κβ and TNF α in the rats fed with heated food. This study applied experimental post test control using Rattus norvegicus Wistar strain. The samples were divided into 5 groups: KN (negative control/fed without heating), KP (positive control/fed heated food but not treated by Rosella extract), R1 (fed heated food and treated by 200 mg.kg-1BW Rosella extract), R2 (fed heated food and treated by 300 mg.kg-1BW Rosella extract), and R3 (fed heated food and treated by 400 mg.kg-1BW Rosella extract). The n-carboxymethyl-lysine levels were measured by using the ELISA, the expression of NF-κβ is analyzed by using immunofluorescence, and expression of TNF - α is observed by immunohistochemistry. There was significantly decreased the levels of n-carboxymethyl-lysine in all groups which were treated by Rosella extracts (R1,R2,R3); p= 0.000, α = 0.05 (p< α). Decreased activation of NF-κβ in all groups which were treated by Rosella extract is significant (p = 0.000), and decreased expression of TNF α in all groups which were treated by Rosella extract is also significant (p = 0.000). Rosella extract can reduce the levels of n-carboxymethyl-lysine, expression of NF-κβ, and TNF α. Keywords: AGEs, anthocyanin, Rosella flower extract, n-carboxymethyl-lysine, NF-κβ, TNF α.

In vitro culture techniques can be used as an alternative problem solving in an effort to provide Ciplukan plant as a raw material of herbal medicine in a sustainable manner. The purpose of this study was to observe the effect of banana homogenate (BH) added into culture medium on shoot regeneration of Ciplukan (Physalis angulata L.) and plantlet development until acclimatization stage. The experimental design used was a randomized factorial group. The first factor was the two varieties of banana fruit namely, Ambon and Raja. The second factor was concentration of BH with four levels, 0 (control), 2.5%, 5% and 7.5 % and each treatment combination was repeated five times. Explant used in this research was the third node of 2 weeks old in vitro shoot after subculture to MS0 medium. Data analysis used ANOVA test. Eight week after culture (WAC) medium containing BH induced higher number of shoot compare to medium without BH. The addition of 5% BH var. Ambon had significant effect on increasing shoot number. Well rooted plantlets produced in MS0 rooting medium also showed high survival rate (66.7%< - 100%) two weeks after transferred to greenhouse. Therefore, the addition of BH into in vitro medium can be an alternative method for micropropagation of Ciplukan.Keywords: Banana homogenate, Ciplukan, micropropagation, nodal explants.

In this article, an epidemic model of HIV/AIDS with treatment is observed. This model consists of five populations: susceptible, educated susceptible, exposed, HIV infected, and AIDS infected. Antiretroviral therapy (ART) is one type of treatment that can be given to individual that is infected by HIV. This medication can prevent the growth of the virus. Exposed individuals are given short-term antiretroviral treatment called Post Exposure Prophylaxis (PPP), while for infected individuals are given treatment by combining two or three types of antiretroviral drugs. Dynamical analysis is performed by determining equilibrium points and local stability analysis. Based on the analysis results, two equilibrium points are obtained, namely disease-free equilibrium point and endemic equilibrium points. The stability analysis shows that the free equilibrium point is locally asymptotically stable if R0 < 1 and the endemic equilibrium point is locally asymptotically stable under certain conditions. Numerical simulations show that giving two medications together has a greater effect in reducing the spread of the disease. Keywords: antiretroviral, dynamical analysis, HIV/AIDS.

The python of Indonesian Sundaland has been traded for its distinct skin colour and patterns. The need for rapid method in cross-species amplification for Indonesian Sundaland python is useful to contribute in management of sustainability harvesting system. In this research, we screened 10 microsatellite primers which are previously used for Australian, New Guinean, Chinese and Burmese pythons and 7 potentially amplifiable primers for African and Asian reptiles. Python breitensteini showed a greater number of alleles (2-8 alleles) than Python bivittatus (1-3 alleles) and Python brongersmai (1-2 alleles). The observed and expected heterozygosity for all species were ranged from 0 to 1.00 and 0 to 0.79, respectively. According to the high cross-species amplification rates, 15 out of 17 primers were useful in assessing the genetic diversity and conservation genetic of Indonesian Sundaland python. Among the 15 primers, MS3 generated the highest number of allele for P. breitensteini (8 alleles), P. bivittatus (3 alleles), and P. brongersmai (2 alleles). We proposed MS3 locus as a suitable marker for Indonesian Sundaland python.Keywords: microsatellite, Python, Sundaland.

This study was therefore aimed to determine the effect of different concentration of estrogen hormone, 17β-estradiol (E2) on feminization for the production of all female, growth rate and survival rate of Pacific white shrimp (Litopenaeus vannamei) postlarvae (PL). L. vannamei PL1 were stocked randomly at a density of 10 ind.L-1 into a 10 L of seawater for each experimental flask with three replicates each. PL1 was immersed in seawater containing 0.5, 1.0 and 1.5 mg.L-1 estrogen hormone, E2 for 4 hours. The experiment was continued for 30 days for larval rearing. At the termination of experiment, the specimens in each treatment groups were weighed and measured individually for their wet body weight (BW) and total length (TL) for the mean weight gain, length gain, and the specific growth rate (SGR) estimation. The mean sex ratio values of male to female postlarvae obtained from control till the highest E2 hormone concentration of 0, 0.5, 1.0 and 1.5 mg.L-1 were 1:1, 1:2, 1:9 and 0:1 respectively. The weight gain and length gain were 40605% and 606% for control, 46310% and 647% for 0.5 mg.L-1 concentration, 49310% and 663% for 1.0 mg.L-1 concentration and 45048% and 628% for 1.5 mg.L-1. The mean SGR BW and SGR TL for control till the highest E2 hormone concentration of 0, 0.5, 1.0 and 1.5 mg.L-1 were 20.00 and 6.51, 20.46 and 6.70, 20.67 and 6.77 and 20.37 and 6.62 respectively. The mean survival rate for E2 hormone concentration of 0, 0.5, 1.0 and 1.5 mg.L-1 were 52.67%, 54.33%, 54.67% and 52.33% respectively. The study shows that while the concentration of E2 hormone increased, the female sex ratio of L. vannamei PL also increased but the growth rate and survival rate decreased at concentration of 1.5 mg.L-1. Thus the optimum concentration of this hormone usage was 1.0 mg.L-1 immersed for 4 hours. Keywords: 17β-estradiol, feminization, growth rate, Litopenaeus vannamei, postlarvae, survival rate.

Bulbil (corm leaf) is one material source of vegetative propagation in Amorphophallus muelleri Blume. Based on the position in branches there are two types of bulbil, middle and edge bulbils, which are different in shape and size. It has been reported that bulbil size affected not only the growth response of seedlings and plants but also the quality of the produced corms. Therefore, the objectives of this experiment were to study the effect of bulbils origin on A. muelleri Blume (Porang) growth and the quality of harvested corms. The quality of corms was assessed based on glucomannan and (CaOx) content. Bulbils from the middle and edge of branches were grown in polybag (f 5 cm) containing compost:fertilizer (1:1) mixed media under 40% shade. Each bulbil origin was repeated 8 times. The results showed that growth responses of plant from middle bulbil were significantly better than that from edge bulbil. However, at the harvesting time, the weight and diameter of corms derived from both types of bulbils were not significantly different. The glucomannan and calcium oxalate (CaOx) content of harvested corms grown from middle bulbil tends to be higher than that from edge bulbil.Keywords: branching, calcium oxalate (CaOx), germination, glucomannan, Porang.
