The Effect of Mahkota Dewa (Phaleria macrocarpa) Pulp Extract by Peroral Administration Toward The Percentage of Capacitation and Acrosome Reaction in Rat (Rattus norvegicus)

This research was conducted to find outthe influence of mahkota dewa (Phaleria macrocarpa) pulp extract against the percentage of capacitation and acrosome reaction of male rat (Rattus norvegicus). The experimental animals used are 20 male rats with the average body weight of 200g and were divided into four different groups. P0 group was the control group and given only CMCNa 0.5%. P1, P2,and P3 was given mahkota dewa pulp extract with a dosage of 7.5 mg/200gr BW/ day, 15mg/200gr BW/day,and 30 mg/200gr BW/day respectively through peroral administration for 14 days. The research used Completely Randoized Design (CRD) and the data was then analyzed by one way ANOVA (Analysis of Variance) followed by Duncan test with the significance of 0.5. The results show that the mahkota dewa pulp extract shows significant impact on capacitation and acrosome reaction of rat. P2 group shows the highest percentage capacitation significance the a mean of 30.00 ± 4.24 and 5.60 ± 0.89 for acrosome reaction percentage.  Keywords: Phaleria macrocarpa pulp extrtact; capasitation; acrosome reaction; sperm potentio

Progress In Knowledge Of Microscopic Tuberculosis Diagnosis Laboratory Training Participants

Indonesia is the second highest tuberculosis (TB)-burden country in the world. TB affects men and women in productive ages. Early and accurate diagnosis of TB is crucial in TB management because it allows prompt treatment with appropriate regimen. Sputum smear microscopy is the most common method used in resource-limited laboratories. The aim of this study is to assess whether adult learning method with student-centered approach can improve knowledge in laboratory techniques in microscopic TB diagnosis. It was a quasi experimental research with one group pretest and posttest design. Pretest was conducted before the training started. During the training, participants attended lectures, discussion sessions, and hands-on laboratory activities. After training, participants were asked to respond to posttest. There were 33 participants of this training (n=33). Paired t-test analysis showed significant difference between pretest and posttest scores (p=6.5x10-9). Variance between pretest scores was 4.00 and variance between posttest scores were 1.34. Pearson correlation coefficient was 0.45. Regardless their level of knowledge before training, participants could achieve relatively equivalent results after training. Significant difference between pre- and post-training test scores indicated that the learning method was effective and the training could improve participants knowledge in laboratory techniques in microscopic TB diagnosis

Novel Application of 3D Scaffolds of Poly(E-Caprolactone)/Graphene as Osteoinductive Properties in Bone Defect

Objective Scaffolds provided a surface on which cells could attach, proliferate, and differentiate. Nowadays, bone tissue engineering offers hope for treating bone cancer. Poly (e-caprolactone) (PCL)/graphene have capability as an osteogenic and regenerative therapy. It could be used to produce bone tissue engineering scaffolds. The purpose of this study was to investigate the ability of PCL/graphene to enhance the osteoinductive mechanism. Materials and Methods The PCL/graphene scaffold was developed utilizing a particulate- leaching process and cultured with osteoblast-like cells MG63 at 0.5, 1.5, and 2.5wt% of graphene. We evaluated the porosity, pore size, migratory cells, and cell attachment of the scaffold. Statistical Analysis Datawas expressedas themean�standard error of themean and statistical analyses were performed using one-way analysis of variance and Tukey’s post hoc at a level of p-value<0.05. Results Porosity of scaffold with various percentage of graphene was nonsignificant (p>0.05). There were differences in the acceleration of cell migration following wound closure between groups at 24 hours (p<0.01) and 48 hours (p<0.00). Adding the graphene on the scaffolds enhanced migration of osteoblast cells culture and possibility to attach. Graphene on 2.5wt% exhibited good characteristics over other concentrations. Conclusion This finding suggests that PCL/graphene composites may have potential applications in bone tissue engineering

Utilization Off-Grid Solar Powered Cold Storage for Economy Improvement of Fishermen in Mangur Island

The absence of access to electricity from PLN on Mangur Island requires fishermen to preserve fish catches by smoking, which causes the selling price of fish to fall. Some fishermen have diesel engines to power cold storage, but the cost of diesel fuel mixed with kerosene is relatively high, which is IDR 17.000/liter. Mangur Island has a large enough solar potential, with a Global Horizontal Irradiance (GHI) value of 5,6 kWh/m2, where this potential can be implemented by installing a Solar Power Plant (solar PV) system. Installation of cold storage with Off-Grid solar powered (Cortagrid) system is a solution to be able to help fishermen preserve fish catches. Off-Grid solar powered with a solar panel capacity of 1 kWp is installed with an additional 4,8 kWh battery. This solar PV system can supply the cold storage load for the fisherman commodity of Mangur Island of 145 Watt and 2 lighting lamps with each power output of 9 Watt. In the CAPEX for the initial solar PV system of IDR 31.906.000, you will get a payback period of 6 years and 4 months and an NPV of IDR 1.112.269,46. Where the solar PV installed can help the community to enjoy clean electrical energy and maximize the potential of solar energy on Mangur Island

Coal and natural gas energy policy for Indonesian electricity security

Electrical energy is very important for national security, so it is important for every country to ensure the availability of electrical energy. The majority of power plants in Indonesia use coal and natural gas energy. The availability of raw materials for electricity generation in Indonesia is threatened because of the policy of increasing the number of exports of raw materials. This study examines the policy on the availability of coal and natural gas energy as an important instrument in national security. This study uses the concept of energy security based on vital energy system vulnerability, availability, accessibility, affordability and acceptability. Then, this study uses qualitative methods to explore policies in managing primary energy, coal and natural gas for the benefit of electricity in Indonesia. The results of this study found that the availability of coal and the accessibility of natural gas are the biggest vulnerability factors for the State Electricity Company as a provider of electricity in Indonesia, in addition to the aspect of price affordability and environmental regime pressures that are factors for the vulnerability of vital energy systems for electricity in Indonesia.&nbsp; &nbsp
