Abstract

Produksi etanol dilakukan dengan beberapa perlakuan antara lain pengenceran larutan stok menjadi 4 variasi konsentrasi, penambahan nutrisi, pengaturan pH, sterilisasi bahan, pendinginan, penambahan inokulum Saccharomyces cerevisiae. Penelitian ini bertujuan mengoptimalisasi pemanfaatan fermentor dan Gas Chromatography untuk fermentasi etanol dan analisis hasilnya. Fermentasi dilakukan selama 96 jam dan pengambilan sampel dilakukan setiap 24 jam. Pengujian hasil fermentasi dilakukan dengan cara melakukan uji kadar alkohol metode conway, uji kadar alkohol metode GC setelah dilakukan pemekatan 5 kali dengan cara destilasi, uji gula dengan metode DNS untuk mengetahui sisa gula yang digunakan dalam fermentasi, uji TPC dan kekeruhan untuk mengetahui pertumbuhan sel Saccharomyces cerevisiae. Hasil uji dibuat grafik dan dianalisis menggunakan SPSS untuk mengetahui penambahan kadar alkohol tiap jam fermentasi, untuk mengetahui apakah data dianggap linier secara statistik dan untuk mengetahui berapa waktu optimal produksi etanol dengan kadar tertinggi. Hasil menunjukkan waktu optimal pemanfaatan fermentor adalah 72 jam dengan kemurnian etanol tertinggi 43,44%.

Abstract

Covid-19 is a new type of disease caused by a virus from the coronavirus class. Covid-19 spreads between humans very quickly and spreads to several countries including Indonesia, in just a few months. In this digital era, the role of media including IoT technology itself is very important for the development of information distribution in a fast, precise, and real-time manner and is able to cut existing distance boundaries. In this study, a wireless data monitoring system for the distribution of Covid-19 was created. This system uses a data parsing method that utilizes the Thingspeak application, to process data using the Arduino IDE and utilizing the ESP8266 as a wireless data transmission medium. The processed data is then displayed on an OLED layer.Keywords:Covid-19, Information, Media, IoT, Digital.

Abstract

Family Archive Restoration Service (LARASKA) is a national archival institution that is present directly in the midst of people who have difficulty in handling community archives damaged by disasters. Since its launch in 2019, LARASKA has helped as many as 790 families and has repaired 33,193 archives. LARASKA ANRI is a service provided to the public free of charge by following established procedures. On February 21, 2021, exactly 1 day after the flood-hit Jabodetabek, the LARASKA ANRI team established a command post at the location to help people who have difficulty coming directly to ANRI. Thus, it is hoped that important public archives or documents as evidence of organizational accountability, both government and private, as well as evidence of community civil rights can be saved. The aim of the researchers from this study was to build a website-based LARASKA application to make it easier for the public to use the online application and conduct assessment analysis using the PIECES Framework.

Abstract

Technological developments in the era of Globalization, are widely used in various fields, one of the developing technologies is the technology on the NodeMcu ESP8266. In the Soil moisture Detector System in Ornamental Plants Using the IoT-Based NodeMcu ESP8266, based on the problem factors that exist in a failure in plant growth, it is very influential in terms of technique and also improper plant watering procedures, can cause plant growth to be disrupted and also withered. To overcome this problem, the author designed a Moisture Condition Detector in Ornamental Plants Using an IoT-Based NodeMcu ESP8266. Where this system can run commands to automatically water plants from soil moisture while simultaneously watering manually with various desired conditions and the system can send notifications that users can receive via telegram. Through the Moisture Level Condition Detector system in this ornamental plant, it can increase the level of effectiveness, so the quality that the plants get will be better maintained.

Abstract

The continuous development of the internet has led to changes in routing complexity. In the context of a wide area network (WAN), network flow optimization becomes a major issue in the selection of the fastest route, which involves routing protocols. Algorithms in routing protocols are designed to determine the shortest path. Therefore, studies are needed regarding how to build a routing algorithm that can be used to get the shortest path in each process. This study aims to reduce network workload and compare the computation involved in determining the shortest path using the Greedy algorithm and the A* algorithm. The simulation results show that the A* algorithm is superior to greedy. The measurement results show that the final cost of the Greedy algorithm is 44 and the A* algorithm is 38. Taking into account the heuristic value for each node, the A* algorithm is superior to the Greedy algorithm in determining the shortest path.
