The hydrogen economy is a shift in the use of fossil energy to energy derived from hydrogen. Currently, Energy experts are trying to find fuel from new and renewable energy, especially in the transportation sector. This study seeks to determine the profile of energy consumption in the city of Semarang, especially in the transportation sector with simulation calculations in a certain year. By knowing the profile of energy consumption in the transportation sector in the city of Semarang, the output of this research is a planning study to build hydrogen economic infrastructure and make possible steps. At the end of this paper, it will be known how big the potential for hydrogen infrastructure development is so that later it can be a guide in determining the right policy in carrying out hydrogen infrastructure development in the city of Semarang. The design capacity of hydrogen production at PT. SAMATOR is 1000 m3/hour. Production breakdown per day : 550 m3/hour x 24hours = 13,200m3. If the production is maximized for 360 days per year, the total hydrogen production in Semarang is 4,752,000m3. In 2020, the demand for hydrogen in the city of Semarang = 1,955,780 m3. With this research data, it can be analyzed that hydrogen production in the city of Semarang can meet the needs of hydrogen for transportation in the city of Semarang.

Background: Spinal anesthesia is a type of extensive nerve block by inserting a local anesthetic drug into the subarachnoid space at the lumbar level (Rehatta, 2019). This method produces anesthesia by blocking transmission, deactivating motor and sensory abilities, thus creating loss of pain sensation in the perineum. lower abdomen to lower extremities. Among the effects of spinal anesthesia that often occur, post-spinal anesthesia headache is a complication that often does not receive special attention. Due to the minor effects of spinal anesthesia. Management of headaches after spinal anesthesia, one of which is using non-pharmacological techniques with Head Up therapy, namely providing a 30 degree head elevation position with the aim of increasing blood flow to the brain in an effort to maximize oxygen flow to the brain which is believed to reduce the sensation of headaches. Objective: To analyze the effect of giving Head up therapy on headaches in post-operative patients with spinal anesthesia. Method: This research is a quantitative research using a type of experiment with a pre-experimental design, post-test control group design. Sampling technique: accidental sampling Population: The population of this study was 300 people. Sample: This study involved 76 respondents with a division of 38 respondents who were given Head Up therapy and 38 respondents who were not given Head Up therapy. Data analysis: Data were analyzed using the Mann Whitney test. The research instruments were Head Up SOP and Posttest Numeric Rating Scale (NRS) questionnaire. This research was carried out in February-April 2024 at Dr Hardjono Ponorogo Regional Hospital. Results: Based on research and after data analysis, the significance value (P value) in the Mann Whitney test was 0.001 (p>0.05). Conclusion: It was found that there was an effect of giving Head up therapy to post-operative patients with spinal anesthesia

Currently, many business people have used information technology as a system in an agency or company. CV. Untung Maju Bersama is a company engaged in the sale of snacks and basic necessities. In its journey, the system used is still using a manual system. To maximize the sales system, therefore an analysis of the sales system design was made using the prototyping method to help improve the existing system. The system used on this website has three users, namely admin, sales, and delivery who have different access rights and have different tasks according to their respective job descriptions. In the analysis of this information system design, a prototyping method is used where the design made must be in accordance with the system to be built. Several features will be added in this proposed design system which did not exist in the previous system, namely the addition of an item tracking feature. This feature allows customers to see how far their orders have been processed. It is hoped that the design of this system can help CV. Untung Maju Bersama in maximizing sales and data management.  Keywords: information systems, order systems, tracking systems, prototyping

The quality of coconut sap (nira) is a significant aspect of the manufacturing of palm sugar. Coconut nira deteriorates fast, and handling nira in the field is challenging due to the long duration of the tapping process, and coconut trees are high, making it tough to reach. The use of natural preservatives to nira help in the preservation of its quality prior to processing. The objectives of this study are to 1) develop a natural coconut nira preservatives formula from mangosteen yellow latex and 2) evaluate the dose of preservatives necessary to maximize nira's shelf life. The study employed a randomized complete analysis with four preservative concentrations of 0%, 1%, 1.5%, and 2%. and four different storage durations: zero hours, six hours, twelve hours, and twenty-four hours.  Chemical analysis of pH, total acid, total sugar, and reduced sugar was performed, as well as sensory evaluation. The study concluded that yellow mangosteen latex can help in the preservation of coconut nira. Preservative concentrations of 1.5% and 2% are still acceptable in 12 hours of storage. While a concentration of 1% is allowed for storage of up to 6 hours. If no preservatives are applied, nira should be processed shortly after harvesting. Nira's quality is deplorable after 24 hours of storage.

In this study, an electric motorcycle has been successfully designed using a 48 V 25 Ah Lithium Polymer Battery. With the advantages possessed by this battery, it is hoped that it can help get a high level of efficiency during testing. This battery will later bear the burden of a BLDC motor with a power of 3 KW. In this test, 2 tests were carried out, namely with and without load. The results obtained are the efficiency value at no-load is 12.35% at the maximum speed of 40 Km/hour and 17.2% at the same speed under load conditions. With these results, it proves that the faster the motorbike goes, the higher the efficiency value will be due to the smaller torque so that it saves battery power.
