Mortar is used as a material for repairing cracked concrete by using the injection method. The mortar tests carried out were mortar flow testing, flexural strength testing, compressive strength testing, adhesive strength testing, and OM observations. The results of the mortar flow test with a mixture of cement without aggregate and the addition of 5.99 grams of glass fiber showed that the mortar could flow in gaps of 1 mm, 3 mm, and 5 mm. The optimum flexural strength test results with the addition of glass fiber are that the cement mixture is more than the aggregate with glass fiber 17.97 gram, the flexural strength value of the mortar is 0.74 MPa. While the optimum compressive strength with the addition of glass fiber is a mixture of more cement than aggregate with glass fiber 17,97 gram, the compressive strength value of mortar is 16.6 MPa. The results of the optimum mortar adhesive strength test value flowing in a gap are the addition of 5.99 grams of glass fiber; the mortar adhesive strength value is 3.31 MPa.

Lithium-ion battery (LIB), as the main power source, dominates the mobile device market due to its high energy density, long shelf life, and environmentally friendly operation. In the rechargeable lithium-ion battery, there are four main components, one of which is the anode. The anode material used is commercial graphite. Thus, this study aims to determine the effect of solid content solvents on battery performance. The main discussion in this study is to analyze the effect of solvent variations of N, N Dimethyl Acetamide (DMAC) on the characteristics of the sheet and the difference in solid content of graphite anode sheets on battery performance. Identification of the formed phase was carried out by XRD, reduction and oxidation reactions by cyclic voltammetry test, battery capacity by charge/discharge test, and study of the electrochemical characteristics of the electrode material by electrochemical impedance spectroscopy test. The best anode sheet is produced by mixing 2.5 mL DMAC solvent at a thickness of 0.07 mm with a solid content of 25%. The results of the charge-discharge test showed a specific capacity of 309.33 mAh/g in the first cycle.","PeriodicalId":323487,"journal":{"name":"Journal of Technomaterial Physics","volume":"58 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113993073","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}

Unfortunately, most fishers still live in poor conditions, including Jaring Halus Village, Secanggang District, Langkat Regency, North Sumatra Province. Previous research has shown that there is much coastal waste, such as Scallop Shells (Placuna placenta), that are not treated, even though it has the potential to help people who are experiencing water crises to get clean water sources. This study aimed to characterize the shells of Scallops and produce calcium carbonate as an activated carbon product to produce clean water. The method used to characterize the mashed scallop shells is X-Ray Diffraction (XRD). In this study, three different sizes, namely 25 μm, 90 μm, and 150 μm, will be compared, and the size and quality selected to produce the best calcium carbonate were tested at different temperatures, namely 800°C, 900°C, 1000°C, and 1100°C. In the x-ray diffraction analysis test, the smallest particle is 25 μm, which has the highest intensity compared to other sizes. The best particle size, which is heated/calcined at a temperature of 1100, has the highest intensity, which can remove all impurities and produce natural calcium carbonate, which is more stable. Based on the study results, it can be concluded that the best calcium carbonate is produced from particles with a size of 25 μm which are calcined at the highest temperature of 1100°C.","PeriodicalId":323487,"journal":{"name":"Journal of Technomaterial Physics","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134166035","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 process of producing the LiMn0,5Fe0,5PO4F/C as an active material in lithium battery cathodes has been successfully carried out by the first forming host structure and then infiltrating the lithium Li ions and the flour F ions. In this study, the synthesis was carried out with various sintering time, 6 hours, 8 hours and 10 hours. The raw materials used in this study are manganese dioxide (“MnO2”), iron (III) oxide (“Fe2O3”), lithium fluoride (“LiF”) and phosphoric acid (“H3PO4”) as the solvents. The synthesis was carried out at a calcination temperature of 720°C for 8 hours. The first mashed use a milling process for about 180 minutes, and placed into the oven, then mashed using a mortar. Then the Mn0.5Fe0.5PO4 sample was added with LiF, mixed with the milling process, placed into a drying oven and was varied with the sintering time of 6 hours for the first sample, 8 hours for the second sample and 10 hours for the third sample. As to produce LiMn0.5Fe0.5PO4F material, followed by carbon coating, namely tapioca and sugar (8%:4%). All three samples were calcined at a temperature of 720°C for 4 hours. The results of XRD analysis showed that the three samples did not experience a phase of change, however only shows a few differences in intensity. The results of FESEM analysis show that grain growth occurs vertically and horizontally due to the presence of the Mn and Fe, and with an exact enough amount of tapioca function as a carbon source to coat the active material, it help to creates pores in the powder so that the presence of these pores could provide an intercalation pathway for the lithium ions. At the end the results of the EIS analysis showed that the highest conductivity value of this study was 0.62 x 10-5 S/cm.","PeriodicalId":323487,"journal":{"name":"Journal of Technomaterial Physics","volume":"343 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132848646","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}

In this research, the gripping vacuum is the main tool in the sheet metal material transfer machine so that the material can be easily moved from the wooden pallet to the TruLaser 3030 fiber machine table. The process of making this machine design requires careful calculation of the formula so that the appropriate machine components are obtained to lift material loads. The components needed in the design of this machine include a gripper vacuum, servo motor, load-bearing shaft, transmission drive, gear transmission, and a steel frame using a 300 x 300 Wide Flange Beam as a support for the whole machine. The sheet metal material used as the load is SS400 material sheet metal with a thickness of 15 mm and an area dimension of 2.44 m x 1.22 m. For this reason, strong components are needed and can withstand vertical and horizontal loads from the movement of materials and the load of the sheet metal material itself. It is recommended to use a suction motor on a gripping vacuum with a suction power of 48 m3/hour and electric power of 1.3 kW. In addition, the servo motor used must be able to withstand a load of 350 kg with a design power of 171.7 watts and a torque of 93 Nm, and straight gears with a ratio of 4:3.","PeriodicalId":323487,"journal":{"name":"Journal of Technomaterial Physics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128981322","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}
