This research will focus on creating an appropriate inventory control system where materials are always available with measurable inventory levels.

In this study, a monitoring system can provide water level reading information using the HC-SR04 ultrasonic sensor with the addition of a flow meter sensor reading feature, and a DHT11 temperature sensor. This flood early warning system is designed to provide a warning when a flood hazard will occur which is indicated by an indication of rising water levels in the river flow with information directly or in real time as a disaster early warning effort. This information will then be displayed on a 16x2 LCD, alarm, and smartphone direct display via Internet of Think technology with ESP8266 as the transmission medium to the cloud network. In addition to presenting information, the tool is also equipped with a servo motor that will activate the opening of the sluice gate so that the water level returns to normal. In the appearance of this information later, the system will display the state of the level of early warning information with a red LED indicator display and a buzzer that lights up when conditions are dangerous and can be accessed via a smartphone.

Therefore, to support sustainable urban development, CS location selection must consider a sustainability perspective in decision-making. In this study, we employed Analytical Hierarchy Process (AHP) method to assess the best placement of CS in Surakarta based on a sustainability perspective. Ten sub-criteria were identified based on a literature review to establish a hierarchy structure of the problem. We distributed a questionnaire to five experts in different fields to assess the importance scale for each sub-criteria and five alternatives location. The priority value and rank of each sub-criteria and alternative were generated. We found that CS 1 obtains the highest-ranking of preferable sites.

 Pembangkit Listrik Tenaga Uap (PLTU) merupakan salah satu sumber pembangkit listrik yang banyak digunakan di berbagai negara karena memiliki beberapa keunggulan diantara-Nya; teknologi sudah dikuasai, bahan bakar murah, dan usia pakai yang lama. Prinsip kerja PLTU adalah mengandalkan energi kinetik dari uap untuk menghasilkan energi listrik yang menggunakan generator untuk memutar turbin. Pembangkit ini menggunakan bahan bakar batu bara maupun bahan bakar minyak untuk memanaskan air. Penggunaan bahan bakar batu bara hingga saat ini masih menjadi andalan di Indonesia karena sumber yang tersedia banyak dan harga yang murah. Akan tetapi, penggunaan batu bara dapat menyebabkan pencemaran gas CO2 yang membahayakan lingkungan dan kesehatan. Untuk itu, desain dan karakteristik turbin uap yang baik, sangat diperlukan agar dapat menghasilkan pembakaran yang efektif dan optimal dengan emisi gas CO2 yang rendah. Dalam review paper ini disampaikan berbagai hasil penelitian yang menunjukkan desain turbin uap yang inovatif, efisien, dan ramah lingkungan dalam menghasilkan energi listrik.
 Abstract
 Steam Power Plant (PLTU) is a source of electricity that is widely used in various countries because it has several advantages including technology that has been mature, cheap fuel, and long lifetime. The working principle of the PLTU is to rely on the kinetic energy of steam to produce electrical energy that uses a generator to rotate the turbine. This power plant uses coal or oil as fuel to heat water. The use of coal as fuel is still a mainstay in Indonesia because of the available sources and low prices. However, the use of coal can cause CO2 gas pollution which is harmful to the environment and health. For this reason, the design and characteristics of a good steam turbine are needed in order to produce an effective and optimal combustion with low CO2 emissions. In this review paper, various research results are presented showing that steam turbine designs are innovative, efficient, and environmentally friendly in generating electricity power.","PeriodicalId":33293,"journal":{"name":"Jurnal Tekno Insentif","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135802872","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}
