Abstract

The maximum solar cell power capacity without load parameter Pm(no-load) = 0.4 watts is used to supply an external electrical load with a resistor R in ohms. Irradiation of the solar cell surface area during the day in bright sunlight supplies an electrical load with a resistor R = 100 Ω which absorbs solar cell power with parameters Psel(R) = 0.09 watts. The power efficiency of a solar cell loaded with a resistor R is expressed as the parameter eff.sel(R) which is the result of a comparison between the power Psel(R) = 0.09 watts and the power Pm(no-load) resulting in a value of eff.sel(R) = 22.5% . Achieving solar cell to more effectively supply a resistor load of R = 100 Ω is efficiency done by adding a parallel FC-75 type dc-dc buck converter device to the solar cell output. Test results: The input power of the FC-75 dc-dc buck converter is Pi(conv.) = 0.178 watts. The resistor load R absorbs the output power Po[conv.(R)] = 0.078 watts. The power efficiency of solar cells using a dc-dc buck converter is expressed as the eff.sel(conv.) parameter. The results of the comparison between the power Po[conv.(R)] and the power Pi(conv.) reach 43.82%. The achieved power efficiency results for solar cells supplying resistor load R using a dc-dc buck converter are eff.sel(conv.) = 43.82%, which is greater than eff.sel(R) = 22.5%.

Abstract

According to SNI 03-0691-1996, paving block is a composition of building materials made from a mixture of portland cement or similar hydraulic adhesive materials, water and aggregate with or without other additives. Pavement construction in Indonesia mostly uses natural aggregates or crushed stone that has a rough and angular surface so that it has excellent adhesion to the concrete. The purpose of this study is to evaluate the effect of the addition of crushed stone on the compressive strength and water absorption of concrete paving blocks, compared with paving blocks of mortar. Paving block test samples were made with 5 variations of composition of cement:sand:crushed stone, namely 1:4:0, 1:4:1, 1:4:2, 1:4:3 and 1:4:4. Each composition was made as test samples of blocks with a size of 20 cm × 10 cm × 6 cm. The test results showed that the average compressive strength of paving blocks with the composition of 1:4:0, 1:4:1 and 1:4:4 was less than 8,5 MPa and water absorption is greater than 10%; thus, they were not classified as paving blocks with grade D. While, the paving blocks with the composition of 1:4:2 and 1:4:3 were classified as paving blocks with grade D.

Abstract

Concrete is a construction material that is widely used in various types of construction. One of the disadvantages of concrete is that its specific gravity is quite high, thus giving a big dead load on the structure. An alternative to overcome this weakness is using lightweight concrete. Therefore, in this study, lightweight concrete will be made with heated styrofoam. The styrofoam used is expanded polystyrene (EPS) type with a grain size of 4-5 mm. Heating of styrofoam the was done at 100°C for 15 minutes and 100°C for 25 minutes. The objective of this study is to evaluate the compressive strength and specific gravity of lightweight concrete using heated styrofoam material with different heating methods and the use of coarse aggregate in the lightweight concrete. Test sample in this study used heated styrofoam as 100% coarse aggregate replacement and 75% coarse aggregate replacement, while the remaining 25% uses coarse aggregate with a maximum grain size of 19.05 mm. To improve workability, a superplasticizer of 0.9% by weight of cement was used. The results of compressive test showed that the optimum value of compressive strength testing of 11.24 MPa in lightweight concrete with coarse aggregate and heated styroforom with the heating for 25 minutes at a temperature of 100°C. The concrete strength was classified into lightweight concrete lightweight structure. The specific gravity of the concrete is 1.578.38 kg/m3, which was classified into lightweight concrete based on SNI 03-3449-2002.

Abstract

One of the meat processing industries in Jombang Regency produces a significant amount of floating sludge waste (oil and fat) in its grease trap unit. If proper waste management is not carried out, environmental issues can arise. This article explores the potential use of floating sludge waste from meat processing industries as a raw material for catfish feed, with the aim of reducing waste, improving the economy, and reducing the production costs of catfish farming. Therefore, this research aims to analyze the best nutritional combination for catfish feed made from waste from the meat processing industry, tofu dregs, organic vegetables, and discarded eggs. The method used is fermentation with EM4 and sugarcane molasses, along with the addition of other waste materials to enhance the nutritional quality of the feed produced. There are five variations of feed compositions analyzed using proximate analysis and compared with SNI 01-4087-2006 concerning Quality Requirements for Dumbo Catfish Feed. The results show that several combinations of ingredients can meet most of the catfish feed quality standards, with the best option is K3 feed that made from floating sludge and discarded egg waste. Although, protein content is still below the standard, this combination has the potential to reduce the cost of catfish farming. This article encourages the development of sustainable, environmentally friendly alternative feeds and the potential reduction of industrial waste.

Abstract

In Indonesia, around 60% of the total 250 million population lives in coastal areas. Kisik Hamlet is one of the settlements located in the coastal area of the Madura Strait and is a densely populated settlement. The increase in population in coastal areas is vulnerable to increasing problems with the quality of the surrounding waters because people still consider rivers, seas, and beaches as places for dumping solid and liquid waste. In this research, we studied and assessed community perceptions regarding the level of awareness and desire to participate in managing domestic wastewater as an initial idea of whether ongoing research will be conducted regarding wastewater processing facilities in this area. The methods used are observation and interviews, questionnaires, and data analysis with SPSS software. The research results show that the majority of people still dispose of gray water through drainage and directly into the sea, and only a small percentage dispose of black water into septic tanks. However, the level of awareness and desire to participate by the community in waste management efforts is quite high. Therefore, it is necessary to implement a waste management strategy by building a community-based domestic wastewater collection system (Communal IPAL), accompanied by ongoing outreach and education to support the successful implementation and evaluation of this strategy.

Abstract

The daily census of inpatients is a means of supplementing medical records in reporting. Given the importance of the inpatient census, its management should be supported by medical record officers who have good knowledge and skills. The method obtained from 3 journals was then analyzed by descriptive method. The method used is Literature Study, carried out with a data set technique to review books, literature search, notes and reports related to research. From some of the literature studied, it was found that there was a discrepancy in the implementation of the inpatient daily census, this can be seen from the indiscipline in filling out the Inpatient Daily Census due to the absence of fixed procedures and technical instructions containing all activities that must be carried out by inpatient ward officers. Other factors are: Man, Money, Methode, inadequate human resources, no socialization of inpatient daily census recording officers with ward nurses, minimal infrastructure, SOPs governing the daily census have not been implemented, and the monitoring process of evaluation of the daily inpatient census is still not regularly scheduled. This is what makes most of the process of conducting the daily census of hospitalizations has not been carried out properly in hospitals.

Abstract

BOR is an indicator of health services that can be used to determine the level of quality, level of facility utilization and efficiency of health services. The impact of decreasing BOR causes a decrease in economic income for hospitals. The aim is to analyze the factors causing the low percentage of BOR at the Mitra Medika Bondowoso Hospital, at the Makassa Community Lung Health Center, at the Sleman Regional Hospital. The results obtained from the factors causing the low BOR are the lack of facilities owned by hospitals, the shortage of staff which causes officers to have to work extra to carry out other tasks so that the officer's workload increases and services will take longer, Discipline of Health Officers, Analyzing priorities , lack of coordination between registration officers, patient care ward officers, errors when inputting patient information data, supervision activities carried out by each room head. The service rates at the hospital in question are the amount of costs that must be paid by the patient to obtain health services, the policies implemented by the hospital and the competition between each hospital.

Abstract

This research aims to analyze the vulnerability of the city of Bandar Lampung to tsunamis with a case study of the 2018 Sunda Strait Tsunami and at the same time provide an overview of past conditions and mitigation concepts to the community that are in accordance with the development of Industry 4.0 today and in the future, using qualitative methods descriptive with case studies. This method is used to reveal the problems behind the visible data can provide greater understanding the phenomena that occur. The research result is known that the potential for Tsunami vulnerability is due to the geographical location and the existence of Mount Krakatau which is a threat to tsunamis caused by earthquakes, volcanic eruptions, coastal and underwater landslides. Apart from that, public ignorance about tsunami in disaster preparedness is needing serious attention. The development of appropriate Industrial 4.0-based tsunami detection and early warning tools that can monitor in real time requires regulatory support as a sustainable management strategy. Efforts to increase people's knowledge and ability to face the threat of disaster can be done through education and outreach by creating disaster mitigation programs that are visionary, easy to implement and right on target using digital media.

Abstract

Online/distance learning is learning that is carried out without face-to-face meetings, or using assistive platforms. Offline or face-to-face learning is a learning system that does not use an internet connection or use a learning assistant platform, in other words students and lecturers meet face to face. This study aims to find out the differences and effectiveness of learning online and offline methods in disease classification and coding courses conducted by Medical Record Students at Esa Unggul University. This study uses a quantitative approach to the research method, namely inferential analysis using the t dependent test instrument. The effectiveness of online learning methods is 33 or 44.0%, and the effectiveness of offline learning methods is 40 or 53.3%. based on the results of the dependent t-test, a significant score of 0.000 was obtained between the effectiveness of online learning and the effectiveness of offline learning. So it can be concluded that there are differences between online learning methods and offline learning methods. So it is advisable to combine learning methods or use hybrid learning methods.

Abstract

Patient satisfaction is a level of feeling of a patient that arises as a result of the health service performance results obtained by the patient after comparing with what is felt. Online registration is a registration process that has the function of being able to serve patients online using a particular website or application. Direct registration is an initial process of service that is carried out at the place of registration at a hospital or health facility and meets in person by officers. Satisfaction can occur because of differences in registration systems. The research method used is inferential analysis with a quantitative approach and the chi square test using the SPSS application. The results of the characteristics of the respondents in this study were young respondents, female, S1/D4 education, private employees, and an average income of > Rp.4,901,798. Online registrants amounted to 91 or 74.4%, and on-line registrants amounted to 101 or 52.6%. In the online registration system, 80 or 87.90% of patients were satisfied and 11 or 12.10% dissatisfied. At direct registration, 73 or 72.30% of patients were satisfied and 28 or 27.70% dissatisfied. The number of patient satisfaction based on the online and direct registration system, namely satisfied as many as 153 or 79.7% of patients were dissatisfied 39 or 20.3%. From the results of the chi square test, the result was p = 0.007, which means that there are differences in patient satisfaction based on the online and direct registration systems. In addition, the results obtained were 0R = 2.79, which means that online registration patients are 2.79 times more satisfied than direct registration patients.
