Abstract

Solar cell tracking system is a system that uses the latest technology with combining solar tracking, the intensity of sunlight absorbed by solar cells can be optimized automatically. The purpose of this study is to make the Arduino-based solar monitoring system and load protection tool. The device is also equipped with an LDR sensor that detects the presence of sunlight, sends data from the LDR to Arduino and delivers signals to linear actuators. When the charge supplied by the battery exceeds the capacity of the battery, the INA219 sensor detects overload and a signal sent to Arduino asking for a relay to release the load. The results showed that tracking solar cell systems were successful in improving the efficiency of solar cells with an average power yield of 0.87 ampere of 12.62 watts from before without tracking the average obtained 0.62 ampere 8.83 atts. The performance of the protection system indicates that the load is cut off when the charging current exceeds the specified limit of 2.6 ampere.

Abstract

The condition of rivers in Indonesia in 2018,  25 rivers were heavily polluted, while in 2019,  38 rivers were  heavily polluted . Efforts are needed to determine the carrying capacity of river pollution loads so that they can be used as guidelines for river management. This study aims to provide an overview of the  conditions of  Indonesia’s rivers through a literature review. This literature review  uses 10 articles from the Google Scholar database for the period 2014-2020. The rivers under study do not have a pollution  load capacity, namely the Code Yogyakarta river, the Bengawan Solo watershed of the Surakarta and Karanganyar sections, the Brantas river in Malang City, the Kupang river, Pekalongan City, the Mahakam river in East Kalimantan, the Winongo river, Sleman Regency, the section of the Brantas river Kekep-Punden Kota Batu, the segment of the Pesanggrahan river of the City; Garang river, Central Java Bedung river, Denpasar City.   Most of the parameters that exceed the loading  capacity of the entire river are BOD, COD, TSS, nitrite, nitrate, phosphate, and ammonia. The source of pollution in most rivers is  unidentified (certain and uncertain sources of pollution). Generally, river management efforts are not carried out in an optimal manner to maintain water quality and condition .

Abstract

This study examines CO2 for the growth of green microalgae by cultivating algal strains in a tank type reactor or fermentor. The study included optimization of the productivity of green algae in the capture of CO2 which can be used as a greenhouse gas catcher. Green algae were isolated from several waters in Banda Aceh and Aceh Besar. The microalgae species of this isolation and its identified species were subsequently cultivated in a tank-shaped cultivation (cultivation) container with 4 flourescent lamps (2x8 watts; 4x8 watts) installed on the outside side of the tank. This study evaluated the comparison of the growth of aerated microalgae O2 (1.25 liters / minute) with fixation of CO2 (1 and 2 liters / minute). The capture of CO2 into carbon dioxide  is done by looking at the growing biomass, and the yield content of oil in biomass. The results showed that there were significant differences in the growth patterns of microalgae given O2 aeration and CO2 fixation. Modified CHU 13 Detmer Modified media does not provide a significant difference to algal growth. With a large intensity of light with a medium that is sufficient to increase the growth of microalgae until it reaches the death phase. Component analysis by Chromatography Gas Mass Spectrometry (GC-MS) shows that the largest component in vegetable oils from green microalgae is Palmatic acid (9.36%), Thiogeraniol (24.63%), Cyclopropane Methanol (2.45%), Farnesol ( 2.39%), Trimethyl (2.78%) and Dodencadien (5.06%).

Abstract

The rain intensity is the high rainfall in unit of time. The length of rain will be reversed by the amount rain intensity. The shorter time the rain lasts, the greater of the intensity and re-period of its rain. The value of rain intensity is required to calculate the flood discharge plan on the drainage system planning area in East Karawang district. Determining the value rain intensity is required the maximum daily rainfall data obtained from the main observer stations in the Plawad station planning area. The method of determination rain intensity analysis can be done with three methods: Van Breen, Bell Tanimoto and Hasper der Weduwen. Selected method is based on the smallest deviation value. Determination deviation value is determined by comparing rain intensity value of Van Breen method, Bell Tanimoto, Hasper der Weduwen. By comparing rain intensity value of the Van Breen method, Bell Tanimoto, Hasper der Weduwen with the results of calculating three methods through the method approach Talbot, Sherman and Ishiguro. Calculation results show that the method of rain has smallest deviation standard is method Van Breen with Talbot approach for rainy period (PUH) 2, 5, 10, 25, 50 and 100 years.
