Abstract

Buildings are places for humans to carry out various activities. Buildings also have a very important role in character formation, embodiment of productivity, and identity. In addition, the building also functions as a place for humans to carry out their activities, whether for daily or residential, religious, business, socio-cultural or special activities. In general, the inspection of the feasibility of the building is carried out by means of visual observation of the physical condition of the building on the components of Architecture, Structure and Test using tools.

Abstract

Websites are very effectively used as information media because there are visual elements in the form of images and text that can impress consumers. Solusimedsosku is a form of e-commerce and an SMM panel platform in Indonesia that provides various social media services. The success and failure of a product development is largely determined by the test results. The testing and implementation that the researchers carried out aims to determine the level of acceptance of the Solusimedsosku website, both in terms of design, service and efficiency so that based on this evidence it can be concluded whether the system being tested has been acceptable or not. The purpose of this study was to find out and analyze the User Acceptance Test Within Information System Solusimedsosku. Based on the results of the analysis, it can be seen that the responses of respondents using the Solusimedsosku information system based on the level of system acceptance taken from 3 aspects of the assessment, namely design (appearance), service, and efficiency are very strong, with a percentage of 84%.

Abstract

The increase in population and increasing human needs along with the times has resulted in an increasing need for non-renewable energy. To reduce dependence on petroleum fuels, one way is to produce biodiesel fuel whose raw materials are obtained from plants. Biodiesel is a fuel that contains ester compounds from plants and animal fats and can be used as an alternative fuel with great potential as a substitute for diesel. This form of methyl ester or ethyl ester compound is environmentally friendly, non-toxic and economical. Coconut (Cocos nucifera) is a type of plant that has one glycerin unit and a number of fatty acids in every coconut oil molecule. Coconut oil has the potential to produce Coco methyl ester which can be used as a raw material for biodiesel. Used cooking oil is used oil from household (domestic) fryers whose remaining frying results or waste is immediately thrown into the environment. According to research from Kumar, the use of coconut oil as a raw material for making biodiesel is able to streamline time and the use of chemicals as solvents in the transesterification process. Before carrying out this research, a preliminary test should be carried out, by testing the %FFA, pH and density of the mixture of used cooking oil and coconut oil. This was done as a reference for further research. The %FFA in the mixture of used cooking oil and coconut oil was the highest at a ratio of 75: 25 (MJ: MK) %FFA value: 4.4%. The pH of the mixture between used cooking oil and coconut oil has the same value, namely: 5 and the specific gravity obtained is: 0.8 gram/ml Keywords: of used cooking oil, coconut oil, % FFA, pH and Specific gravity

Abstract

The continuous and increasing use of fuel, causing depleting and non-renewable petroleum reserves, has the potential to cause an economic crisis in the future. With the current depletion of petroleum reserves, it can encourage efforts to find alternative fuels. Biodiesel is a type of alternative fuel that is environmentally friendly and can be renewed because it is made from vegetable oil (biodiesel) mixed with diesel oil. This research was conducted to determine the specifications for the content of Fatty Acid Methyl Ester (FAME) in biodiesel B30 using the Fourier Transform Infrared (FTIR) method produced at the Laboratory of PT. X. The results of the analysis of the Fatty Acid Methyl Ester (FAME) content of BioSolar B30 products at PT. X on March 25, 2021, the fame earned 30%, on April 7, 2021 the FAME content obtained 29% met the specifications (On Specifications) stipulated by the Decree of the Director General of Oil and Gas SK No. 146.K/10/DJM/2020. Keywords: B30, FAME, Fourier Transform Infrared (FTIR)

Abstract

The concept of smart homes has revolutionized the way we interact with our living spaces, offering a myriad of benefits ranging from enhanced convenience to improved energy efficiency and security. This paper provides a overview of smart home technologies, their applications, and their impact on modern living. Firstly, we delve into the underlying principles of smart home systems, which typically integrate Internet of Things (IoT) devices, sensors, actuators, and connectivity solutions to create interconnected ecosystems. Secondly, we focus on the functionalities offered by smart home technologies. Advanced features such automatic lighting and security control. These features optimize user needs and experiences before built. Additionally, we address the challenges and considerations inherent in adopting smart home technologies, such as interoperability issues, privacy concerns, cybersecurity risks, and the digital divide. Effective deployment and integration strategies, along with robust privacy and security measures, are crucial for ensuring the reliability, scalability, and user acceptance of smart home ecosystems. In conclusion, the evolution of smart home technologies continues to redefine the way we inhabit and interact with our living spaces. As these systems become increasingly sophisticated and ubiquitous, they hold the potential to not only enhance our quality of life but also contribute to a more sustainable and connected future.

Abstract

Pengolahan minyak goreng bekas menjadi biodiesel merupakan salah satu alternatif yang perlu dikaji dalam pemanfaatan minyak goreng bekasagar tidak menjadi limbah. Dalam pembuatan biodiesel dari minyak goreng bekas, diperlukan kualitas minyak goreng dengan angka asam kurang dari 1%. Salah satu cara untuk menurukan angka asam adalah dengan proses adsorbsi menggunakan arang aktif. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh adsorbsi minyak jelantah dengan menggunakan kulit pisang kepok pada pembuatan biodiesel dari minyak goreng bekas, dan untuk mengetahui karakteristik biodiesel yaitu angka asam, titik nyala, massa jenis, viskositas dan gliserol bebas dari biodiesel yang dihasilkan dengan bahan dasar minyak goreng bekas yang dibuat dengan proses transesterifikasi dengan proses adsorbsi arang aktif kulit pisang kapok terlebih dahulu. Pemanfaatan minyak goreng bekas sebagai bahan dasar untuk membuat biodiesel berhasil dilakukan. Minyak goreng bekas yang akan dimanfaatkan sebagai bahan dasar biodiesel sebelumnya dilakuka pra – treatment berupa proses adsorbsi menggunakan arang aktif kulit pisang kapok. Semakin lama waktu yang digunakan untuk proses adsorbsi minyak goreng bekas menggunakan arang aktif akan semakin baik hasilnya. Karakteristik biodiesel yang terbaik dari penelitian ini di dapatkan dari proses adsorbsi selama 2 jam dengan titik nyala 162°C, angka asam 2,288 mg KOH/gram, massa jenis 830 kg/m³ dan viskositas 6,76 cSt. Keywords: Biodiesel, adsorbsi, arang aktif, penggunaan minyak goreng
