Morphology of bioplastics presented that palm oil wrapped bioplastics granules which influenced hydrophobicity properties of bioplastics compared by increasing contact angle of bioplastics from 45.95 0 (0% of palm oil) to 61.98 0 (5% of palm oil). This result indicated that the addition of palm oil could develop the properties of bioplastics to hold absorbing water molecules. Moreover, the melting point of bioplastics also affected shifting temperature from 115 0 C to be 100 0 C that could save the energy needed during heating process. FTIR analysis showed that C=O group at wavenumber 1747 cm -1 was dependable the interaction between starch-glycerol and palm oil. Furthermore, the addition of palm oil would accelerate the biodegradation process.

However, in Indonesia, the recycling process for extracting precious metals has not been much processed, even though they contain precious metals such as copper and gold. This research was conducted to find a more economical and environmentally friendly treatment process by using an oxidizer of Hydrogen Peroxide (H 2 O 2 ) and Manganese Oxide (MnO 2 ) and reducing the level of HCl used. Observation of metal leaching results using Atomic Adsroption Spectroscopy (AAS) showed the value of recovery (recovery) of gold and copper reached 59.1% and 59.8% for 0.5M HCl + 2.5% H 2 O 2 . However, the recovery value of copper has reached its optimum point at the addition of 1.5% H 2 O 2 . The use of 3% & 5% MnO 2 results in recovery values of 12% and 24% for gold and copper. Observation of the cross section shows the dissolution of the copper metal from the PCB and accompanied by a change in the color of the solution from clear to green, the more concentrated the more the amount of dissolved copper metal shows the characteristic of CuCl solution. The results of the comparison of the two types of oxidizers show that H 2 O 2 is better than MnO 2 in producing higher Cu and Au metals more than 3 times.","PeriodicalId":365391,"journal":{"name":"Jurnal Sains Materi Indonesia","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121702302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structure of reactor core must ensure the position of fuel to be kept in its position, to ensure the control rods can get into the guiding canal, and to ensure the flow of the gas coolant. One of the stressor of the graphite material degradation is neutron exposure. The impact of neutron exposure is the change in mechanical properties such as modulus of elasticity. In order to ensure the integrity of the materials, an in-service non-destructive inspection is implemented. The aim of this study is to develop non-destructive inspection method in order to predict mechanical properties of graphite materials. Inspections were done using Ultrasonic Flaw Detector with 35×35×55 [mm] block-shaped specimens made of graphite IG-110. Two types of transducer were used to generate longitudinal and transversal waves with the same frequency of 5 MHz. Two mechanical properties were predicted, that are isotropic characteristic and the modulus of elasticity. The predicted value of the modulus of elasticity was verified by conducting compressive tests using 10×10×10 [mm] cube specimens. According to the ultrasonic propagation velocities resulted from ultrasonic inspection results showed that the graphite IG-110 is an isotropic material. From the calculation of the modulus of elasticity based on measurement results of transversal and longitudinal waves propagation, IG-110 graphite has a value of modulus of elasticity of 9.1 GPa. Compared to the modulus of elasticity measured from compressive test, this value was 10% lower. It can be concluded that the ultrasonic non-destructive inspection can be used to predict mechanical properties of the IG-110 graphite.","PeriodicalId":365391,"journal":{"name":"Jurnal Sains Materi Indonesia","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122229301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of iron oxide (Fe3O4) magnetic nanoparticles in the biomedical field is still being explored, mainly related to its toxicity and side effects. This article reported results of the study aimed at analyzing the effect of chitosan-coated magnetic nanoparticles (NPM-C) on rat blood profiles. Magnetic colloid as much as 1 ml (concentration of 5 mg NPM-C / mL aquabidest) for 1 kG rat body weight was injected through intra-venous to the treated rat group (4 Wistar rats aged 6 months; weight ± 275 grams; male sex) while another four rats injected with sterile aquabidest used as a control group. The blood taking from each group of rats was carried out on 1 day before injection and several days after injection (days 1, 7, 14, 21, 28) through veins in the tail. To these blood samples, a series of blood profile analyzes is carried out including basic hematology, blood chemistry, and fragility of the erythrocyte membrane. The results of the analysis showed no significant differences between blood profiles after treatment and control, which indicated that chitosan-coated magnetic nanoparticles did not trigger cellular stress responses in the blood. The stability of blood magnetism analyzed by VSM (Vibrating Sample Magnetometer) also shows that magnetic nanoparticles are detected in the blood and tend to decrease in number with increasing time, so it is thought that these nanoparticles can be degraded or have been distributed into organs. These stable properties are analyzed due to an existence of chitosan coating around magnetic nanoparticles. Based on this study it can be concluded that up to the given concentration limit, iron oxide nanoparticles coated by chitosan are not toxic and have the potential to be used as drug carriers, MRI contrast agents, and other biomedical applications.","PeriodicalId":365391,"journal":{"name":"Jurnal Sains Materi Indonesia","volume":"2011 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114795891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
