Platelet rich plasma (PRP) and platelet rich fibrin (PRF) are sourced from human blood and have role in bone recovery. Both of them could be incorporated into scaffold for bone regeneration. Synthetic coral scaffold is a natural mimicking of sea coral designed for bone regeneration. It should have bio degradability and bio absorbability that influence new bone formation process. The purpose of this study is to investigate the degradation, swelling profile and gel fraction of synthetic coral scaffold incorporated with PRP or PRF. Synthetic coral scaffold consists of gelatin, calcium carbonate, and sodium nitrate as dispersant agent. It is divided into 3 groups, incorporated PRP, PRF, and no-incorporation. Scaffold was soaked in phosphate buffer saline (PBS) and incubated in 37° C for 24 hours. Scaffold weight was measured in every 30 minutes to observe the swelling profile and gel fraction. Degradation profile was observed after 1, 3, 6, 24, 48, 72, and 96 hours of soaking. Acceleration of degradation was measured after soaking with HC1 1N for 1, 3, 6, 24, 48, 72, 96 hours until the scaffold ran out. The result shows significant differences among PRP, PRF, and control group. PRP incorporation has slow degradation, good swelling and higher gel fraction that presents the strengthening of scaffold structure.

Shrimp production is currently constrained by many diseases. These diseases are conventionally prevented by administering chemicals as immunostimulants, with their attendant side effects. Alternative natural ingredients as immunostimulants in shrimp production are being sought, and Majapahit plant (Crescentia cuje L.) is one. In vitro and in silico studies on the plant’s stems, leaves and fruits showed the plant’s desirable effects on the immune system of Vannamei Shrimp, as the plant contains important bioactive compounds (e.g. carotenoids, phenolics, alkaloids, pectin, tannins, flavonoids and terpenoids). The present study determined the ability of Majapahit fruit powder mixed into shrimp feeds in enhancing the immune system of the seafood. Liquid chromatography–mass spectrometry (LC-MS) revealed quercetin flavonoids as the effective active ingredient in the powder, which in silico study proved to be an effective immunostimulant for shrimps.

Cardiovascular disease is the biggest cause of death in the world with the number of deaths reaching 17.7 million people (31% of the total number of deaths). The main cause of cardiovascular disease is a disturbance in the function of the heart and blood vessels caused by atherosclerosis due to the deposition of cholesterol in artery walls. High Density Lipoprotein (HDL) functions to transport free cholesterol contained in the endothelial peripheral tissue to HDL receptors located in the liver so that it can be processed to be used as bile. Therapy to increase levels of HDL in the blood using okra juice (Abelmoschus esculentus L.) can be done in rats that have been given high-fat feed. The purpose of this study was to determine the effect of okra juice (Abelmoschus esculentus L.) on HDL levels in rats fed high fat. The study was conducted with giving okra juice (Abelmoschus esculentus L) with dosage difference of 1500 mg/kg bw, 3000 mg/kg bw and 6000 mg/kg bw. The research design used was complete random design with post-test randomized group design with a number of replications 5. Testing of HDL levels was carried out by the CHOD-PAP (Cholesterol Oxidase Para Aminophenazone) method. The research data were analyzed using one-way Anova followed by LSD tests. The results of the study giving okra juice (Abelmoschus esculentus L.) to HDL levels by induction of high-fat feed at a dose of 6000 mg / kg body weight were significantly different from lower dosage. Conclusion, okra juice (Abelmoscus esculentus L.) has a positive effect on increasing HDL levels..

Virgin Coconut Oil (VCO) has been known in Indonesia since a decade ago. This oil is made from coconut milk using unheated method, such as enzymatic, physical, and chemical method. The VCO has been proofed to have many health benefits such as for treatment of hyper-cholesterol, diabetes, viral and bacterial infections. Also, the oil has been utilized in the cosmetics industry for beauty skin care. In the increase of VCO demand for pharmaceutical industry, this study was conducted to find the method for VCO production using an environmentaly friendly process. The environmentally friendly process was conducted to maintain the sustainable environment. This paper deals with the enzymatic method of VCO production. The enzyme was obtained from fresh pineapple juice that is proofed contain bromelin. The enzyme will cleave the polypeptide bond of emulsifying agent in the coconut milk. Further, the oil will be separated and then collected as the VCO. During this work, the amount of the fresh pineapple juice varied to measure the rate of VOC production. Based on the observation during the production, it is found that the increase of fresh pineapple juice added increases the VCO production.

The need for biodiesel as an alternative fuel will increase along with the increasing energy consumptions and the depletion of fossil fuel reserves. Jatropha oil and soybean oil are potential raw materials for biodiesel. Each raw material gives different properties to biodiesel. Mixing the two types of oil makes it possible to improve the quality of biodiesel. The aim of this study was to determine the effect of variations in the composition of the oil mixture on the biodiesel properties. Jatropha oil was mixed with soybean oil in various compositions. The mixture was heated and stirred for 60 min at 90°C. The more the percentage of soybean oil biodiesel, the viscosity of the biodiesel mixture decreased. Mixing with 20% soybean oil has a significant reduction in viscosity. The increasing percentage of soybean oil also influences the higher heating value of the biodiesel mixture.
