Abstract

Biomass is a potential energy source and can be developed as an alternative energy source as a substitute for fossil fuels. Biomass can be converted into briquettes or charcoal which can be used as an energy source, such as for the drying process in processing crumb rubber and smoked sit. Biomass charcoal briquettes or biobriquettes are made from biomass charcoal, either in the form of parts that are intentionally used as raw material for briquettes or leftovers or waste from agro-industrial production/processing processes. For example, wood, coconut shells, palm shell charcoal, bamboo waste, corn cobs, rice husks and tobacco stem waste can be raw materials for biobriquettes. Apart from that, waste from the crumb rubber industry in the form of chips can also be used as biobriquettes. Biobriquette manufacturing technology is widely available. Making biobriquettes requires supporting materials such as clay, starch glue, water and other mixing materials. The composition of these materials really depends on the type of raw material for making biobriquettes. Before making biobriquettes, biomass must first be converted into charcoal, then the charcoal is crushed, mixed and molded into various briquette shapes such as cylinders, cubes and eggs. From several research results, in general the calorific value produced from biobriquettes is not significantly different compared to coal briquettes. Therefore, biobriquettes can be used as fuel for the natural rubber drying process.

Abstract

The increasing need for electricity for the community and the cost constraints for using fossil energy, require innovation in creating electricity sources using hydropower (PLTA). To increase the efficiency and stability of the output wave, a converter is installed in this circuit which can produce an output voltage that is lower or higher than the input voltage by using a PWM switch duty cycle. By installing a converter in a hydropower generating circuit, of course it cannot accommodate very large amounts of voltage due to the limited specifications of the components used. The Buck-Boost circuit used must use accurate mathematical calculations and must be simulated first to prevent and minimize the occurrence of errors and undesirable things.

Abstract

Fire is an event that is often sudden and can cause major losses, both in terms of property and life. Fires can occur in various places, from residential homes, office buildings, to forests and open land. So a safety system is needed that can provide assistance as quickly as possible for dangerous situations that occur at any time. Apart from that, the safety system must be designed as well as possible so that when an emergency occurs it can be used according to its function and provide maximum assistance. To minimize the risk of fire, it is necessary to have a fire protection safety system that is available in a planned manner, especially one that is installed and absolutely must be observed. Therefore, what needs to be done is to create a light fire prevention system using light fire extinguishers in every building in the Company. The method used in this research is systematic steps by obtaining data obtained from the internet, journals and existing regulations. The results of this research are in the form of calculations and placement of APARs in one building

Abstract

Solar energy is an alternative energy source that is increasingly popular in various places because it never runs out and is environmentally friendly. The application of solar energy that is commonly used today is solar panels. However, solar panels only produce electrical energy at a relatively low voltage. Therefore, a tool is needed that can increase the electrical voltage produced by solar panels so that they can be used optimally. In this case, Buck-Boost Converter and CUK Converter are two types of converters that can be used. Buck-Boost Converter is a type of converter that can change the input DC voltage into an output DC voltage with a value that is higher or lower than the input voltage. Buck-Boost Converters are suitable for use on solar panels that produce fluctuating voltage. Meanwhile, the CUK Converter is a type of converter that can also change the input DC voltage to an output DC voltage, the same as Buck-Boost but with a simpler design. However, the weakness of the CUK Converter is that its performance is worse when the electrical load changes. When used on solar panels, both types of converters can be used depending on the needs and conditions of the solar panels used. If the solar panel produces a fluctuating voltage, then a Buck-Boost Converter can be used to produce a stable output voltage. However, if the solar panel produces a stable voltage, then the CUK Converter can be used as a simpler alternative

Abstract

The increase in population in Indonesia is directly proportional to existing economic activities. The main need that every human needs is food, so many food industries continue to develop. One of these industries is the tofu making industry. Many of these industries result in several problems such as unpleasant odors from waste and damage to the water ecosystem in rivers. On the other hand, the use of microalgae is still often considered inadequate, so innovation needs to be carried out to optimize the usefulness of microalgae. Therefore, researchers made an innovation by using microalgae to remove COD and eliminate bad odors in tofu dregs liquid waste. This research method is an experiment using data from journals and the internet. Data processing is descriptive in the form of data results that are compared with materials used every day

Abstract

Ships are a means of transportation that connects islands inside and outside the country's territory. Maritime workers are seafarers who are employed from various places and make various journeys to and from their homes. Since its founding, the International Maritime Organization (IMO) has attempted to reduce ship accidents by setting minimum safety standards for ships and their crews (Wahyuni ​​et al., 2021). As a result, accidents caused by technical or mechanical problems within the ship's structure are currently very low. However, human error is one of the most important sources of problems for the global maritime community. For example, Rothblum (2012) shows that human error accounts for more than 75% to 96% of marine accidents. Barsan, Surugiu, and Dragomir also show that more than 80% of maritime accidents are caused by human error (TRANSNAV, 2012). In carrying out this action, it is necessary to investigate the problem from which information can be drawn. So the method that will be used in this research is the HFACS method. Method (HFACS) is an accident analysis tool used to analyze Human Factors..

Abstract

The Attorney General's Office is an institution that plays an important role in law enforcement in Indonesia, it is also an institution that can provide a sense of justice for people who commit crimes. In this journal, the issue raised is how the Genah Adhyaksa house or the Restorative Justice house can provide principles of justice for perpetrators of crimes and can reduce crime rates, especially in the area of the Gianyar District Attorney's Office. The purpose of writing this journal is to find out how the crime rate existed in the Gianyar district attorney's office before and after the existence of the Genah Adhyaksa House or the Restorative Justice House, whether it increased, according to, or was static. The research method used is the empirical research method. The results of this study are that the crime rate in the Gianyar District Prosecutor's Office has decreased slightly when compared to previous years before the existence of the Genah Adhyaksa Restorative justice house. However, until this writing was written, the crime rate at the Gianyar State Prosecutor's Office was still quite high because these crimes arise from the personal conscience of the person who committed the crime. The progress of Justice Genah Adhyaksa's Restorative House can be seen on the official website of the Gianyar State Attorney's Office.

Abstract

The use of innovative technology, the need for effectiveness and efficiency is prioritized in various fields. Smart door lock is a new technology for using doors automatically. From this, a new innovation was created with technological developments where the microcontroller was made more complex by using cards according to scheduling. The method used in this research is the experimental method and prototype method. After assembling each component and programming the system so that the RFID system is realized, it is necessary to test the series of components that are ready. The way this prototype system works is included in a closed system because it provides feedback on the output produced. The work of this system starts from the RFID sensor which will identify the card by taking data from the RFID number on the card. The card used will be registered in the programming system so that only registered cards can be processed by the system. When the card is attached to the RFID sensor, the RFID sensor will process the card as input and then control it using the Arduino Uno microcontroller. Then the output from this system is movement on the servo which can be applied to the door lock.

Abstract

The Balinese cow are able to utilize low quality feed to meet basic the needs The reserch aims to study the diversity of rumen bacteria of Balinese cow that is maintained in the people’s farm of Somba Opu District of Gowa Regency. The subjects of this research consisted of 8 adult Balinese cow that were obtained from the people’s farm of Somba Opu District of Gowa Regency. Adult Balinese cow was divided into two groups, i.e. control group consisting of 3 cows and treatment group consisting of 5 cows. The former was given local feeds of straw and field grass and the latter was given the same feed plus suplement feed. The results of the research indicate that nutritional content in the feed for control group consists of crude protein (22.81%) and crude fiber (4.41%), while the one in treatment group consistens of crude protein (7.47%) and crude fiber (35.19%). This indicates that nutritional content of the treatment group is higher than that of control group. The high nutrition in the feed of treatmnet group is indicatede by high protein and low fiber. This is caused by the use of urea, fish meal, and soybean meal. The high fiber in the feed is caused by feed materials consisting of straw and field grass. Thus, the result indicates that nutritional content in the treatment group is higher than the one in control group and the pH value of fluid rumen is affected by the content of VFA, NH3, and lactic acid.
