Abstract One of the trees that has fruit with high acid content that has the potential to be used as an alternative energy source is the acid contained in Singi (Dillenia serrata Thunb.) fruit. Therefore, this study aims to test the ability of the singi fruit to turn on the LED lights and determine the value of voltage, current and electrical power in the fruit. This research was conducted at the Laboratory Ministry of Forestry, Faculty of Forestry and Environmental Sciences, Halu Oleo University. In June-July 2019 using an experimental method for 5 days by measuring the acidity (pH) value of voltage, current and electric power. The results showed that the LED was on until the 5th day but the value of the electricity content tended to decrease, namely the first day with a power value of 7.533 watts and the fifth day 1.722 watts. While the acidity (pH) of the singi fruit which is decreasing over time affects the value of the electrical content contained in the solution of the singi fruit.

New Renewable Energy (EBT) is an efficient solution to overcome the deficit of fosil energy resource such as crude oil and coal. In addition to this pandemic of Covid-19 in Indonesia made the price of crude oil in the world dropped dramatically to reach around $25/barrel crude oil of WTI as of May 8, 2020. Every resources in this world stores electricity. Nonetheless this resources need special processing so that they can be converted into electrical energy. This Research is focused in Banana Peel. Currently we know that the consuming of Banana fruit still increased especialy in the pandemic of Covid-19. Hence the more Banana fruits are consumed, the more Banana Peels are remained. This research aims to find the solution from the Banana Peel wastes in this pandemic – processing them and converting them into eco-alternative energy – by keeping the energy into the battery. The methods used in this research used an exxperimental method using the application of the Ohm’s law which aims to test the hypothesis by testing four banana peel samples (Ambon, Muli, Raja Hijau, and Raja Palembang). The results of this research showed that harvest the electricity from banana peels (BPEEH) can help the efficiency of deficit fosil energy resources due to this pandemi of Covid-19. It was showed that one battery of the banana peels pasta or BPEEH can give voltage 1.28 Volt and electricity current is 2.13 Ampere. In addition to for 12 batteries of BPEEH assembled series can turn on the 6 Volt LED lights for 4 to 5 days.

Renewable energy is needed as an alternative energy source. One of the implementations of renewable energy is the Solar Power Plant (PLTS). PLTS is a component that uses solar cells to convert solar energy into electrical energy. Unfortunately, the output power of this solar cell depends on the intensity of the light which causes the output power to enter the load to be unstable. Sometimes the PV power decrease because of the shading effect. From this problem a converter is needed to keep the system output voltage. The converter used in this research is the zeta converter. This Zeta converter can operate like a buck boost converter. The output of the system used is not stable. So that to stabilize it requires good control. In this paper using PI controller to control this system in order to keep the output system stable. 3. The error generated using the PI Control on the system is only 0.34%.

<p class="AbstractEnglish"><strong>Abstract: </strong>Acoustic energy (sound) that is wasted in environment has potential to be alternative energy to produce electrical energy. This paper presents an experimental study of the effect of Helmholtz resonator neck diameter on the output electric power of an acoustic energy harvester. The cavity of the resonators is a cube-shaped with size of 30 cm ´ 30 cm ´ 30 cm made of acrylic. The resonator neck is cylindrical and has 8 cm length with four diameter variations of 5,2 cm, 6,9 cm, 8,2 cm, and 10,4 cm. A 6-inches subwoofer loudspeaker is used as acoustic transducers that converts sound into electric current. The experiment is performed by giving sound with SPL of 90 dB in the frequency range of (20-150) Hz. The output rms voltages from the loudspeaker are measured at a 5.0 ohm load resistor. It is found that there are always two peaks in the frequency spectrum that provide maximum electric power, namely at 27 Hz and 55 Hz. These peak frequencies do not depend on the neck diameter. On the other hand, the larger the neck diameter, the higher the generated electrical power. The highest rms electric power produced are 3.03 mW and 2.25 mW at the first and second peaks, respectively.</p><p class="AbstractEnglish"><strong>Abstrak: </strong>Energi akustik (bunyi) yang terbuang di lingkungan memiliki potensi menjadi salah satu energi alternatif untuk menghasilkan energi listrik. Makalah ini memaparkan tentang studi eksperimental pengaruh diameter leher resonator Helmholtz pada alat pemanen energi akustik terhadap daya listrik yang dihasilkan. Rongga resonator Helmholtz berbentuk kubus berukuran 30 cm ´ 30 cm ´ 30 cm terbuat dari akrilik. Leher resonator berbentuk silinder sepanjang 8 cm dengan empat variasi diameter yaitu 5,2 cm, 6,9 cm, 8,2 cm, dan 10,4 cm. Loudspeaker jenis subwoofer dengan diameter nominal 6 inci dipasang disisi belakang rongga resonator digunakan sebagai transduser akustik yang mengubah bunyi menjadi arus listrik. Eksperimen dilakukan dengan memberikan gelombang bunyi dengan SPL (sound pressure level) 90 dB dalam rentang frekuensi (20 - 150) Hz dan mengukur tegangan listrik rms keluaran dari loudspeaker pada resistor beban 5,0 ohm. Diperoleh bahwa selalu terdapat dua puncak spektrum frekuensi dengan daya listrik maksimum, yaitu pada 27 Hz dan 55 Hz. Frekuensi-frekuensi puncak ini tidak bergantung pada diameter leher resonator. Di sisi lain, ditemukan bahwa diameter leher yang semakin besar menghasilkan daya listrik yang semakin besar. Daya listrik rms terbesar yang dihasilkan (pada diameter 10,4 cm) adalah 3,03 mW dan 2,25 mW masing-masing pada puncak pertama dan puncak kedua.</p>

This study investigates the use of an alternative energy source in the production of electric energy to meet the increasing energy requirements, encourage the use of clean energy, and thus reduce the effects of global warming. The alternative energy source used is a mechanical energy by piezoelectric material, which can convert mechanical energy into electrical energy, that can convert mechanical energy from pressure forces and vibrations during activities such as walking and traveling into electrical energy. Herein, a pilot device is designed, involving the modification of a bicycle into a stationary exercise bike with a piezoelectric generator, to study energy conversion and storage generated from using the bike. Secondly, the piezoelectric energy harvesting system is used on bicycles as a micro-mobility, light electric utility vehicle with smart operation, providing a novel approach to smart city design. The results show that the energy harvested from the piezoelectric devices can be stored in a 3200 mAh, 5 V battery and power sensors on the bicycle. Moreover, 13.6 mW power can be generated at regular cycling speed, outputting 11.5 V and 1.2 mA. Therefore, the piezoelectric energy harvesting system has sufficient potential for application as a renewable energy source that can be used with low power equipment.
