Lithium-ion batteries are the recent main store of electrochemical energy that have been widely used for electronic equipment, electric vehicles, and also renewable energy storage such as wind and solar. Lithium-ion batteries have many electrochemical advantages but lithium availability in nature is reduced very quickly and its distribution is uneven throughout the world. Sodium is attractive as an alternative to lithium insertion for secondary batteries because of its abundant availability and oxidation reduction potential to standard hydrogen electrodes only 0.3 volts higher than lithium. This study aims to synthesize hard carbon from nipah shell biomass using thermal methods of low-temperature pyrolysis (lower than 200 oC) followed by high-temperature pyrolysis (higher than 1000 oC). Characterization is carried out by iodine number analysis to determine porosity and SEM-EDX to determine texture and morphology. The result of the analysis of carbon iodine number is 346.86 mg/g while SEM-EDX analysis showed that carbon has a structure similar to a combination of graphene and nano-tube carbon.

One source of regional income for Cilacap Regency is the management of vehicle parking lots. Currently, parking area management is carried out by recording the identity of the parking location based on the street name, while the withdrawal of parking fees is carried out by towing officers who come to the parking location and then record it in a book. The current management of parking lots is still inaccurate because there are several street names that have more than one parking area which results in data redundancy. The conventional parking fee collection system causes frequent discrepancies in reports due to the potential for misuse of parking fees. The absence of tools that can be used by related agencies to control reports is the cause of the problem. The research objective is to develop an information system by applying LBS technology which functions to detect parking points precisely and QR Code Detection which functions to detect the identity of parking attendants. System development uses the ADDIE model. The results of the research are an information system for mapping parking lots and picking up parking fees based on Andorid which can help manage vehicle parking lots which includes mapping the location of parking lots and picking up vehicle parking fees.

The rapid development of information technology encourages innovation in various fields, including the field of disaster geographic information services. Lack of information on ambulance service providers is often the cause of delays in handling victims of natural disasters. Besides, the absence of information regarding the nearest route for ambulances to emergency service providers such as health centers and hospitals adds to the length of time for handling victims of natural disasters, resulting in increasingly severe victim losses, including life. This study aims to create a geographic information system that can be used to provide information on the location of the nearest ambulance service provider and emergency unit service. The system development research method uses the extreme programming method by implementing the Djikstra algorithm to determine the shortest route. This system testing process consists of testing the Djikstra algorithm and testing functionality using a usability scale. Djikstra's algorithm testing is done by comparing the results of calculating the shortest route for two location points with the results obtained when using the Google Maps application. The results of this test indicate that the system can display shorter routes than the routes generated by the Google Maps application. On the other hand, testing system functionality using the usability scale method to see system acceptance by users shows that the application can be used properly with a score obtained that is 77.

The availability of fuel oil is decreasing while the level of consumption is increasing. This encourages the need for the development of alternative energy to minimize the crisis. This study investigates the characteristics of fuel and automatic transmission combustion engines. The fuel used is butanol variations B7, B12 and B18 (7%, 12%, and 18%) and pertalite (RON-90). The gasoline engine used has a capacity of 110 cc with a compression ratio of 9.5:1, an automatic transmission system, and air conditioning. The performance test equipment used is the Dynotest-chassis type 50L-BRT. Fuel variations are applied to an engine performance test by using engine speeds of 3000-9000 rpm. The results showed that the use of 18% butanol increased the output power and thermal efficiency by 8.3 kW and 923.95 kPa at 8000 rpm. torque and MEP (average effective pressure) increased by 8 N.m and 923.95 kPa at 5000 rpm. Meanwhile, SFC (specific fuel consumption) decreased by 0.35 kg/kWh at 8000 rpm.

The use of material that is specified as armor steel has a high resistant value. The quenching and tempering process is done to improve the toughness of the material. The process uses a temperature of 900oC on the quenching process with water medium and tempering temperatures of 125oC and 175oC holding time for 30 minutes. The tests include the impact test to determine the increase in the material and fractography to determine the ductility of the material. There is a decrease in the value of the impact that occurs after the quenching process. The impact value is increasing due to the tampering impact of 32 J during the quenching process to 50 J. The fractography shows brittle fractures with ridges as a feature of brittle fractures. Rapid cooling rate processes in the quenching process cause cracks in the quenching specimens.

Photovoltaic is one of the environmentally friendly power plants. One of the problems using photovoltaic is the low efficiency level. Therefore, a method is needed to optimize photovoltaic performance. The use of fuzzy logic control for dual axis tracking system is used in this study to optimize photovoltaic performance. The dual axis tracking system functions to keep the photovoltaic always perpendicular to the direction of the sun's arrival so that it has more optimal output power. The input of the tracking system comes from the LDR sensor which is installed on each side of the Photovoltaic. This sensor is combined with RTC to anticipate weather changes (cloudy). LDR and RTC sensor data as input for fuzzy logic controller. Based on the results of the research, the output power of the Photovoltaic tracking system is 9.363 Watts or 46.82% of the Photovoltaic specifications. Meanwhile, static photovoltaic with conventional installation has a power of 7.247 Watt or 36.23% of the specification. So that Photovoltaic with fuzzy logic control for dual axis tracking system is 29.20% more optimal.

Heat treatment is a process of renewing the metal structure by heating the specimen to a temperature below the melting point and a certain time, which is then cooled in a cooling medium to change the physical and mechanical properties. This study aims to determine the effect of quenching media and tempering temperature on the hardness value of DC 11 steel. This study used an experimental method with hardening at 990 °C and a holding time of 30 minutes with quenching media with SAE 10W-30 oil and 3.45 NaCl solution. %. After that, tempering was carried out at 250 °C, 350 °C, and 450 °C with a holding time of 2 hours. Then, the specimens were tested for hardness using the Rockwell method. Based on the results of the study, it was found that the effect with the highest hardness value was found in the quenching media with 3.45% NaCl solution and a tempering temperature of 250 °C of 49.6 HRC. The conclusion obtained is that the higher the tempering temperature, the lower the hardness value.

Preeclampsia is a disease of pregnant women, causing many complaints, including dizziness. Massage is the right solution to reduce dizziness since the use of analgesic drugs is not recommended. Submission of massage information can be more effective through digital technology. The purpose of this research is to build an application based on Augmented Reality (AR) as a guide for facial massage movements for midwives and pregnant women to deal with complaints of dizziness for pregnant women. The method used is the Multimedia Development Life Cycle (MDLC), which consists of the stages of making a concept, making a design, collecting materials, combining materials, testing, and distribution. Black box testing on 10 scenarios produces a value of 100%, which means the application can run properly. In addition, usability testing using the System Usabilities Scale (SUS) method shows a value of 69.5, which means that the application has the "good" criteria and is acceptable to users.

Information systems can assist hospital management in improving services at a hospital. The software development method used in making hospital management applications is using the waterfall method which one of the stages is testing. The problem in system development is that the testing process is not optimal and focuses more on system development so that errors can be found at the implementation stage. System testing is a permit for an error in the system being developed. The aim of the research is to check the design details, use the program design control structure procedurally and run the program to find errors. The method applied to carry out the testing phase in the hospital management system is the Whitebox method using the cyclomatic complexity and graph matrix approaches. Testing will be carried out on the process of managing inpatient data in the application. The results of the research from testing the hospital management system using the cyclomatic complexity approach are that it can provide information on the minimum number of tests and ensure that all program structure paths are used at least once. In addition, the results of the graph matrix test are the probability side that will be carried out.
