World energy demand has resulted in a surge in renewable energy needs. One of them is biomass. The gasification process takes place in a reactor called a gasifier, and the most effective way is to implement the Fixed Bed method on the downdraft gasifier. The process was executed in a downdraft gasifier because of the gas-making process without stopping the ignition and producing a small amount of tar. The biomass raw material used in this study is wood pellets because of their abundant availability in Indonesia. This research discussed numerical simulations for downdraft gasifier by utilizing wood pellet biomass as a raw material. The simulation technique is computational fluid dynamic with the DPM (Discrete Phase Model) because it can predict the experiment result details more precisely. The simulation results have shown that the convergence rate got better with the longer process iteration time. The simulation results were close to 100% in real-scale laboratory research results.

Competition between industries currently requires the industry to continue to improve in improving the industrial system. Machine flexibility is one of the programs to improve industry's ability to increase competitiveness. In meeting consumer demand, general purpose machines have become one of the foundations for industrial systems in producing various types of products. Machine performance will decrease in line with the age of the machine / component and the length of the machine's operation. Maintenance planning / component replacement is one way to reduce downtime. A lathe is a general purpose machine, which has components that are often damaged, such as gear and control cables, which cause a lot to stop using the machine. Scheduling replacing components is a vital process in reducing lost time and minimizing costs arising from decreased machine performance. The focus of this research is determining the component replacement schedule that can meet these two criteria. This can be achieved by applying the age replacement method. The Age Replacement method is basically looking for a balance point between the probability of component failure and component reliability to obtain the optimal probability value of total down time. By estimating the pattern of component failure with the Weibull distribution, calculations are made for the two components that are most frequently damaged on a lathe. The results obtained are the time to replace the components, the replacement period and the costs arising from the optimal replacement of these components. By paying attention to the total down time probability value, it can be concluded that the optimal time to apply preventive replacement on the gear component and the control cable component.

The global pandemic that has attacked Indonesia has had a negative impact on many sectors of life. In the food strength sector, many livestock producers have experienced a decline in income and production. In an effort to overcome the risks and impacts that are more severe, the author makes a tool with a monitoring and control system in a closed chicken coop as an effort to increase the quality and quantity of eggs from laying hens. This tool uses an ESP32 controller with a user interface through the Blynk application over a WiFi network based on the Internet of Things. The monitoring function of this tool is for monitoring temperature, humidity, and light intensity in the cage. While the control function that is run on this tool is a function of controlling the volume of drinking water for poultry, remaining poultry feed, and the temperature in the cage which is regulated by flowing cold or hot air in each room of the temperature control box according to the temperature set desired by the user. Based on the test results, this system has a good success rate with a sensor reading error value of not more than 5%.

The solar cell module absorbs electrons from sunlight where the electrons are converted through a semiconductor intermediary in the solar cell module. In Kalimantan, in particular, it has the potential to install a Solar Power Plant because it is traversed by the equator. However, there are various disadvantages of the Solar Power Plant, namely the building is quite large, so it needs extra monitoring so that all the conditions of the Solar Power Plant can be known. One of the data communication methods in question is using the telemetry method or long distance communication. There are many ways for the telemetry method, one of which is to use a wireless system with a connection to a cloud storage database. In short, data in the field can be sent to users wherever they are. Data sent to previous users is sent through a cloud storage database where the data can be accessed by anyone. For data sent from the Solar Power Plant in the form of incoming and outgoing voltages as well as incoming and outgoing currents. Based on the research results, it is known that the design of the data transmission system for incoming and outgoing voltages as well as incoming and outgoing currents is made from a variety of component tools used are the solar cell module, Robotdyn Mega Wi-Fi, voltage sensor, current sensor, SCC, inverter, and battery. In the process of sending data using a Wi-Fi router, data originating from the sensor is sent to Robotdyn where inside Robotdyn there is a Wi-Fi module which will then be assisted to be forwarded via a Wi-Fi router whose internet network source uses GSM. The data sent to the cloud storage database is assisted by the PHP programming language and to display the website using the HTML programming language.

The graduate profile is the role of the graduate of the study program or field of expertise / field of work planned after completing education from the study program. The determination of the profile of study program graduates is generally carried out based on the results of the assessment of stakeholder needs. Based on data from the Ministry of Research, Technology and Higher Education, the IT study program is one of the most majors or study programs in Indonesian universities and the highest number of enthusiasts choose this study program each year. Each year, graduates of IT study programs have a large number of graduates, both vocational and non- vocational colleges. The number of IT graduates is large but they have low graduate competencies, even they do not have competencies in the IT field so that their work is not in accordance with the graduate profile that has been designed. Therefore, it is necessary to conduct research to classify the profile of graduates who have worked based on tracer study data using the Naïve Bayes Classifier method. This study uses attributes, namely study program, value criteria, gender and field of work and the labels used are status (Linear and Non-Linear). The results of the study on the classification of the profile of graduates using the Naïve Bayes Classfier method show that alumni work not according to the profile of graduates by 73% and according to the profile of graduates by 23%, with a data accuracy rate of 87% and are included in the good classification category.
