Abstract

Palm oil mill effluents (POMEs) can contaminate soil, groundwater, and also the water environment. The increasing production of crude palm oil in Indonesia produces an enormous amount of POME waste. Therefore, a method is needed that can be used to purify POMEs. In this paper, an electrocoagulation (EC) method for purification of wastewater and a design to optimize this method are presented. An optimization experiment was performed by varying voltage and process time. The applied voltages were 6, 9, and 12 V and the process time was varied between 30 and 150 minutes. The measured parameters were: COD, BOD5, pH, TSS, lipids, and NH3-N. The result shows that optimum conditions were achieved at a voltage of 12 V and a process time of 150 minutes with COD at 8000 mg/L, BOD5­ at 12000 mg/L, pH at 7.46, TSS at 324 mg/L, lipids at 17.8 mg/L, and NH3-N at 0.65 mg/L. The results are in accordance with environmental quality standards for pure water. This study proves that the proposed EC method is effective in purifying POMEs from pollutants.

Abstract

Sepeda motor merupakan transportasi pribadi yang paling banyak digunakan masyarakat untuk pergi ke tempat yang dekat bahkan jauh sekalipun. Disamping harganya yang tergolong mudah dijangkau, sepeda motor lebih mudah untuk melalui kemacetan dan jalan sempit sekalipun. Sepeda motor seringkali menjadi target pencurian dikarenakan lemahnya pengawasan terhadap kendaraan. Umumnya sepeda motor hanya memiliki keamanan seperti kunci pengaman konvensional, berbeda dengan kendaraan seperti mobil yang memiliki perangkat GPS (Global Positioning System). Pada penelitian ini dibuatlah rancang bangun sistem keamanan sepeda motor yang menggabungkan mikrokontroler dengan aplikasi android. Mikrokontroler yang digunakan adalah Arduino Mega 2560 yang dilengkapi dengan modul GPS, modul SIM900 dan relay. Penerapan teknologi IOT (Internet of Thing) sebagai media yang digunakan untuk komunikasi antara alat dan aplikasi android. Modul GPS akan memberikan koordinat posisi sepeda motor dan ditampilkan pada aplikasi android melalui komunikasi internet menggunakan modul SIM900. Relay dirancang untuk memutus aliran listrik pada mesin kendaraan. Berdasarkan hasil dari rancang bangun ini nantinya dapat diimplementasikan pada sepeda motor untuk dapat mengetahui posisi kendaraan yang telah dicuri.

Abstract

Simple ML Detector for Multiple Antennas Communication System. In order to support providing broadband wireless communication services against limited and expensive frequency bandwidth, we have to develop a bandwidth efficient system. Therefore, in this paper we propose a closed-loop MIMO (Multiple-Input-Multiple-Output) system using ML (Maximum Likelihood) detector to optimize capacity and to increase system performance. What is especially exciting about the benefits offered by MIMO is that a high capacity and performance can be attained without additional frequency-spectral resource. The grand scenario of this concept is the attained advantages of transformation matrices having capability to allocate transmitted signals power suit to the channel. Furthermore, product of these matrices forms parallel singular channels. Due to zero inter-channels correlation, thus we can design ML detector to increase the system performance. Finally, computer simulations validates that at 0 dB SNR our system can reach optimal capacity up to 1 bps/Hz and SER up to 0.2 higher than opened-loop MIMO.

Abstract

In the last few decades, researchers have been conducting various studies in search of alternative energy sources to reduce dependence on fossil fuels and anticipate future energy scarcity. One such alternative energy is hydrogen, which can be obtained through various methods, including electrolysis of water. Hydrogen possesses the characteristics of being flammable, odorless, colorless, and tasteless, necessitating the development of a rigorous monitoring and protection system to mitigate potential hazards. In this study, a monitoring and protection system was designed for the operation of an electrolyzer using a Dry Cell type HHO Generator. The system employs the concept of the Internet of Things, where data is connected through the internet network. The data received includes hydrogen concentration readings, electrolyzer operation automation, electrolyzer operating status, and hydrogen gas leak detection in the system. The research results obtained showed that the higher the concentration of electrolyte and the voltage supplied to the electrolysis process, the faster the production of hydrogen gas is accelerated, accompanied by an increase in temperature. If a leakage occurs in a system, the occurrence of the fire triangle will be faster when the concentration of electrolyte and the voltage supplied are greater.

Abstract

Cultivation of lettuce in a greenhouse is considered a sustainable agricultural technique. Unlike conventional farming, which is susceptible to water shortages, pests, and other uncertainties that can lead to inconsistent and lower-quality lettuce production, hydroponic cultivation in a greenhouse ensures not only high-quality lettuce production but also continuous availability of crops, protected from extreme weather conditions such as droughts and pests. Although greenhouse cultivation is an effective approach, in lowland areas like Sekayu City, the capital of Musi Banyuasin Regency, the microclimate inside the greenhouse can be relatively high and less favorable for lettuce growth. Lettuce ideally thrives in highland regions with a temperature of around 28°C and humidity of 76%. Therefore, it is necessary to control the microclimate inside the greenhouse to optimize lettuce growth. This control requires electrical energy to operate various electronic devices in the microclimate control system, such as exhaust fans and cooling pad water pump. In this study, a solar power electrical system is designed to meet the energy needs for operating a lettuce greenhouse in Sekayu City, Musi Banyuasin Regency, South Sumatra Province. The research was conducted for 31 days, from July 1 to July 31, 2023. The highest power output was recorded on July 31, 2023, at 11 kWh, while the lowest output occurred on July 20, 2023, at 5 kWh. The research utilized an MMPT inverter, which prevents overcharging and maintains a constant 50 A input power when charging the battery. Additionally, an IoT system was used to monitor the performance of the solar power generation system, facilitating data collection on electricity production.

Abstract

Integrated wastewater is one of the contributors to wastewater that can harm the environment, thus fast industrial expansion must be followed by advancements in wastewater processing systems. Because the presence of contaminants in integrated wastewater can cause several issues for persons and the environment, integrated wastewater processing is required. One type of integrated wastewater processing is the production of hydrogen gas as a new and sustainable energy source. The electrocoagulation process may be used to convert integrated wastewater into hydrogen gas. One type of integrated wastewater processing is the production of hydrogen gas as a new and sustainable energy source. The electrocoagulation process may be used to convert integrated wastewater into hydrogen gas. In this study, oxyhydrogen (HHO) was produced from integrated wastewater utilizing two process stages: integrated wastewater processing with an electrocoagulator, followed by the process of getting HHO using an oxyhydrogen reactor. A NaOH catalyst was applied at different concentrations of 0.1 M, 0.2 M, 0.3 M, 0.4 M, and 0.5 M with an electrolysis period of 5 minutes to produce hydrogen gas. The addition of the NaOH catalyst is intended to find the optimal concentration for the production of hydrogen gas. According to the findings of the study and analysis, the optimal NaOH catalyst concentration for producing hydrogen gas is 0.5 M with hydrogen content of 346 mg/m3.Keywords: electrocoagulation, oxyhydrogen, integrated wastewater, renewable energy
