Published: June 2023

Population growth and economic development in most countries of this world have increased global energy needs. The international energy agencies indicated that the increase in energy consumption in developing countries is faster than in developed countries, and it requires almost twice their current capacity to meet energy demand by 2020. It is also estimated that the total energy consumption in the world will increase by 44% from 2006 to year. 2030. Therefore, alternative energy sources must be specified to meet our energy requirements and to conserve traditional fossil fuels. Solar energy is a renewable energy source. This clean energy has the potential to meet a large amount of the world's energy demand. In the field of renewable energy and energy efficiency, it has brought stability to the negative impact of carbon emissions due to the increase in energy consumption in the world, as well as the reduction of major fossil fuel sources. Photovoltaic thermal technology (PVT) has been developed since the 1970s. PVT system generates electrical and thermal energy simultaneously. The aim of this hybrid system was to use a cooling PV panel to enhance electrical efficiency, while, at the same time, utilizing thermal energy for the heating process. Most studies on PVT systems focused on the air or water-based medium for the heat transfer. In recent years, nanofluids and phase-change materials have been used with working fluid to enhance PVT thermal performance, in addition to adding some design parameters.

Potential of Beetroot (Beta vulgaris L.) and Purple Sweet Potato (Ipomoea batatas L.) as Natural Indicators of Formalin in Food
Authors: Burhan Amelia Handayani 
Published: June 2023

ABSTRAK
Formaldehid yang lebih dikenal dengan nama formalin ini adalah salah satu zat yang dilarang dan berbahaya apabila ditambahkan pada makanan. Namun bagi sebagian orang terutama produsen makanan tetap menggunakan formalin sebagai bahan pengawet makanan. Penelitian ini bertujuan untuk menciptakan alternatif pengujian terhadap formalin dalam makanan yang ramah lingkungan dengan menggunakan bahan alami yang mengandung antosianin. Salah satunya menggunakan umbi-umbian yaitu umbi bit dan ubi ungu.
Sampel yang digunakan dalam penelitian ini adalah umbi bit dan ubi ungu yang dibeli di Superindo Kotagede, Yogyakarta. Pengujian dilakukan secara kualitatif dengan membuat larutan indikator alami umbi bit dan ubi ungu berbagai variasi konsentrasi, yaitu 50, 75, dan 100% v/v kemudian diujikan pada larutan formalin dengan kadar 0,1%, 1% dan larutan tahu berformalin. Pengujian yang dilakukan yaitu uji warna, waktu respon, uji resprodusibilitas, uji spesifisitas, dan uji stabilitas.
Berdasarkan hasil penelitian, sari umbi bit dan ubi ungu dapat digunakan untuk mengidentifikasi formalin. Untuk uji warna dan uji spesifisitas indikator alami dari sari umbi bit memiliki performa yang lebih baik dari pada indikator alami dari sari ubi ungu. Sedangkan pada uji waktu respon, uji resprodusibilitas, dan uji stabilitas kedua larutan indikator alami tersebut memiliki performa yang sama. Apabila akan menggunakan larutan indikator alami umbi bit dan ubi ungu sebaiknya dibuat variasi konsentrasi sari umbi bit dan ubi ungu terhadap alkohol 50% v/v. Hal tersebut dikarenakan pada variasi konsentrasi 50% v/v menghasilkan warna indikator yang paling baik daripada variasi konsentrasi 75% dan 100%, serta memiliki perubahan warna yang lebih baik saat ditambahkan pada sampel formalin.
