Pengaruh Inokulasi Nikel Dan Magnesium 4% Terhadap Struktur Mikro dan Kekerasan Besi Cor Ductile pada Pengecoran Dinding Tipis dengan Ketebalan 2,3,4,5 Milimeter
Get PDFThe use of materials that can withstand high temperatures is usually stainless steel and cast steel is often used. Cast steel has the disadvantage of being able to cast lower than cast iron. Although cast iron has a higher castability, it also has a weakness for its thin thickness, its phase structure tends to change from graphite to cementite. Cast iron casting at a thin thickness will result in white cooling so that the phase is difficult to form graphite. Ductile cast iron has a spherical graphite shape. This research is to characterize thin and high temperature ductile cast iron material. The research was conducted by casting gray cast iron and inoculated with FeSiMg plus Nickel. The mold is made ladder with 4 thickness variations. Testing the chemical composition of solid conditions with a spectrometer with ASTM E415- 8 standard for ductile/nodular cast iron.

Get PDFModern agriculture faces various challenges, such as limited water resources, labor shortages, and demands for efficiency in crop management. Chili peppers, as one of the leading horticultural commodities, require precise watering arrangements to support optimal growth. This research aims to design and implement an Internet of Things (IoT)-based automatic plant watering system supported by a Solar Power Plant (PLTS) as the main energy source, in order to create a smart and sustainable agricultural solution. The system design involves hardware and software integration using ESP32 as the main microcontroller, a soil moisture sensor, a DHT22 temperature and humidity sensor, a rain sensor, and an INA219 sensor to monitor power consumption. The power system consists of a 20 Wp solar panel, a solar charge controller (SCC), and a 12V 10Ah battery that supplies power to all components, including a 12V water pump as the watering actuator. All sensor data is sent in real-time to the Blynk application via a Wi-Fi connection, allowing users to monitor and control remotely using a smartphone. The system operates automatically based on soil moisture values. If the moisture falls below the 50% threshold, the pump will turn on until it reaches optimal moisture. Test results show that the system successfully maintains soil moisture in the ideal range of 50–70% in both sunny and cloudy weather conditions. The average power consumption is 4.79 watts when idle and 12 watts when the pump is active. The system has also proven to be able to operate independently for 24 hours a day without relying on PLN electricity. Compared to conventional methods, this tool can reduce manual intervention by up to 90%. Thus, this system offers an innovative and applicable solution to support sustainable agriculture that is energy-efficient, efficient, and adaptive to the development of digital technology through the application of IoT and renewable energy

Penerapan Prinsip Green Banking Dalam Mendukung Mekanisme Bursa Karbon Di Indonesia
Get PDFThis study aims to analyze the legal role in supporting the implementation of green banking and to examine the application of green banking principles in supporting the carbon exchange mechanism in Indonesia. The background of this research is based on the urgency of climate change mitigation, which requires the active role of the financial sector in sustainable financing. Green banking is a banking concept that integrates environmental sustainability aspects into its operations, while the carbon exchange is a carbon credit trading instrument aimed at reducing greenhouse gas emissions. Both are strategically linked in supporting the transition towards a green economy. This research uses a normative juridical approach with data sources consisting of primary, secondary, and tertiary legal materials collected through literature studies. The analysis is conducted qualitatively to examine the correlation between regulations governing green banking and the carbon exchange, including OJK Regulation No. 51/POJK.03/2017, OJK Regulation No. 14/2023, and Presidential Regulation No. 98/2021. The results of the study indicate that the legal role in green banking in Indonesia includes establishing standards, criteria, and obligations for financial service institutions to implement sustainability principles, while also encouraging the financing of projects that generate carbon credits to be traded on the carbon exchange. The application of these principles has the potential to strengthen the achievement of the Nationally Determined Contribution (NDC) target and the 2060 Net Zero Emission commitment. However, successful implementation requires regulatory harmonization, strengthened emissions verification, and increased literacy among businesses and the banking sector
