Lemna sp. is known to have several bioactive compounds and polysaccharide macromolecules that can function as immunomodulators to affect non-specific immune responses to increase the body's resistance to pathogens. This study aims to determine the potential of catfish eye extract as an immunostimulant by observing non-specific tilapia immune parameters. The extraction method used was 96% ethanol maceration for 2 days with a ratio of 1: 4. The experimental design used a Completely Randomized Design with 5 treatments (doses 0.2, 0.4, 0.6 mg/kg, control + and control -) and 3 replications. The non-specific parameters of immunity observed included total plasma protein (Bradford method), superoxide dismutase and lysozyme activity. The data obtained will be analyzed using ANOVA, if there is a significant difference, it will be further tested with Duncan Multiple. Range Test (DMRT). The results showed that the highest total plasma protein was found in treatment C (giving an extract of 0.3 mg/kg body weight) with an average total plasma protein after 12 days of maintenance of 4.99 g / dL. The extract dose of 0.3 mg/body weight showed a rapid decrease in SOD and increase Lysozyme activity.

Comparison of the length, weight and condition factor of Nila Tilapia (Oreochromis niloticus) was studied on oligotrophic waters (Wonorejo Reservoir) conducted from July to August 2018 and eutrophic waters (Selorejo Reservoir) on February to March 2019. All of the reservoir are in the East Java, Indonesia. The total sample from Wonorejo Reservoir about 79 fish from 3 times sampling (every two weeks), but the fish Sample from Selorejo Reservoir are 35 from 4 times sampling every week. The Nila Tilapia from Wonorejo Reservoir are 15.3 ± 2.5 cm (length) and 74.6 ± 38.6 grams (weight) but fish from Selorejo are 17.8 ± 2.2 cm average length and 114 ± 35 grams for the weight. The condition factor of Nila Tilapia in both reservoirs was relatively the same, with an average value was 1.01. The Nila Tilapia caught from Selorejo Reservoir (eutrophic) is relatively heavier and bigger than in the Wonorejo Reservoir (oligotrophic) even though the hook size is smaller. Fish from the Selorejo Reservoir (eutrophic) is easier to get food so that the average fish is larger.

In primigravidas, the first stage of labor has a longer duration than multiparous. The first stage of labor in primiparous is around 13-14 hours, while in multiparous it is about 7 hours. Prolonged labor is one of the causes of maternal death. Yoga in pregnancy can maintain elasticity and strength of the ligaments of the pelvis, hips, and leg muscles, so that it can reduce pain during labor and provide space for the birth canal. The comparative analytical research method used pre-experimental design with the one shot case study design. With a sample of 26 trimesters III primigravida pregnant women who were divided into 2 groups, namely n = 13 groups who did prenatal yoga, and n = 13 groups who did not do prenatal yoga. The analysis of this research was univariate and bivariate using the Mann Whitney test. Assessment is carried out during the delivery process. As a result, the intervention and control groups with active phase I labor duration obtained p = 0.000, and perineal rupture p = 0.000. There was a significant difference in the length of the first stage of labor and perineal rupture between the yoga group and the non-yoga group. Prenatal yoga affects the duration of the first stage of labor and perineal rupture.

Malaria is still an essential epidemiological disease worldwide, including in Indonesia. Several approaches are performed to control the disease, as well as vaccine development. The Cysteine-rich interdomain region α of Plasmodium falciparum erythrocyte membrane protein 1 (CIDRα-PfEMP1) is a pivotal domain in the malaria pathogenesis make it a malaria vaccine candidate. The development of the malaria vaccine is performed using recombinant technology. Recombinant protein production is an important step. The study aimed to determine the optimized condition for CIDRα-PfEMP1 recombinant protein expression in Escherichia coli BL21(DE3) expression system. Serial IPTG concentrations from 0.05, 0.1, 0.3, and 0.5 mM and two different incubation periods of 4 h and 8 h were optimized. The recombinant protein expression was visualized in SDS-PAGE, measured using the Bradford protein assay, and calculated using software Image J. SDS-PAGE visualization showed a 27 kDa band expressed CIDRα-PfEMP1 recombinant protein. The optimized condition for CIDRα-PfEMP1 recombinant protein expression was at 0.03 mM IPTG concentration and 8 h incubation period.

Cardiac arrest is one of the highest causes of death in the world. This condition requires the handling of cardiac arrest based on the chain of survival concept. The chain of survival concept is carried out by nurses who have sufficient skills to handle cardiac arrest. Skills can be obtained either through education and training based on simulation or using technology such as self-directed videos. The purpose of this study was to identify the differences in self-direct video and simulations of nurse skills in advanced cardiac life support. This study used Quasi-Experimental Design by pretest-posttest with a control group approach. The 42 respondents were divided into two groups. Skills are measured before and after learning with each method. Data were analyzed using Wilcoxon and Mann-whitney tests. The results showed changes in skills before and after learning in the two methods, with each p-value = 0.000. There were no differences in skills changes before and after learning in both groups with a p-value = 0.437. Learning using self-directed videos and simulations can improve nurse skills in carrying out advanced cardiac life support.
