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.","PeriodicalId":442343,"journal":{"name":"Jurnal Teknovasi","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124211146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The maritime marketplace application aims to facilitate sellers and buyers in buying and selling agricultural and livestock needs as well as food needs online. In its business process, the maritime marketplace application uses the B2C (Business to Customer) business model. Where business activities are carried out by producers to consumers using electronic media directly. The development of the Android-based Maritani marketplace is built with the Flutter framework and uses the Dart programming language. At the time of making the Maritani marketplace application for system development using the waterfall method, the development was started with an analysis of system requirements, then carried out the application display design (Graphic User Interface) implementation stage of the application implementation with the Dart programming language. The result of this research is a market application that can have a positive impact on users, both sellers and buyers. In the Maritani application which has a greater opportunity from the community to share knowledge with other sellers, sellers do not need to be afraid of losing consumers, features and regulations of the online market which greatly affect to increase the credibility and safety of the seller's shop, sellers are not required to have large capital.","PeriodicalId":442343,"journal":{"name":"Jurnal Teknovasi","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126001685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":442343,"journal":{"name":"Jurnal Teknovasi","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131930623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.

The discussion of this theme is the imbalance in the number of users between the two implementations of the system where the application of this crossing system technology should be able to solve queuing problems and also increase effectiveness and efficiency. This analysis uses descriptive analysis by assessing data and information obtained from various sources. The method used is to describe systematically through the research flow that is researched in a precise, simple and easy to do by conducting a theoretical study to deepen the immigration crossing system.
