Abstract

The need for a charge controller for the use of electrical energy sourced from solar panels and DC generators is very necessary for the purposes of the battery function as electric power in the inverter which functions as a voltage source. Usually the battery is used for inverter purposes in meeting household electricity needs as a substitute for PLN. The charging process will occur if the output voltage from the DC voltage source is higher than the battery voltage to be recharged. In this study, the charging process is based on PWM settings, and consists of 2 types, namely boost mode and float mode which are distinguished from the duty cycle setting. The voltage reading on the voltage divider sensor using a resistor has an error of less than 6.22% at the source terminal, and 6.89% at the battery. However, the charging process is able to provide an average voltage of 13.14 Volts on the battery (12 Volts), so that the charging process can run well.

Abstract

The use of information technology is now so massive, that even reports on community activities have also used information technology. Online forms for reporting are widely used and very easy to create, with complete features. One of the products from Google is Google Forms. Starting from reservation, registration, data collection, reporting, and many activities of sending information and data can be done using this form online. The results of the data have also been presented in full, either in the form of sheets or graphic information, so that the manager or admin does not need to process it again. In the development of information needs, it turns out that the information needs from the google form are not only needed by managers or admins, but some parties need that information in real-time and do not have to log in as managers or admins, so technology is needed to distribute the data and information and processed or presented in a real-time reporting information system. In the google form, several tools have been provided such as Google APIs, Share to Sheet, CSV, etc. to share information with other parties. This study performs modeling in the design of web application architecture using real-time data from google forms based on CSV files and has been tested and produced an application model that can be pasted into other applications so that information from the google form can be conveyed without having to log in to the manager or admin of the google form.

Abstract

Strobilanthes cusia is a herbaceous shrub that is a source of blue dye, grows well above an altitude of 1000 m. This plant is very easy to breed, and for the purposes of making this plant dye, it can be harvested every 3 months. The use of strobilantes cusia leaves as natural dyes has been managed by UMK Shibiru in the Ngadirejo area, Temanggung. The results in the form of pasta have been marketed to various regions and even abroad. Some of the products are directly used to dye fabrics to serve the needs of batik in various regions. The raw materials in the form of leaves and twigs are macerated using water, within three days. The effectiveness of the process can still be improved by examining the factors that influence the effectiveness of the maceration process. In this study, it was studied how the effect of material size and time on the effectiveness of the maceration process. The results showed that the smaller the size of the material and the greater the time used, the results obtained will be better, which was indicated by the intensity of the color of the extract produced. By using a UV-Vish Spectrophotometer, two colors were detected in the extract solution, namely blue with a wavelength of 409 nm and red with a wavelength of 678 nm. However, from further observations by observing the absorbance, it can be seen that the red content is smaller than the blue color. The best result in this study was the maceration process using a leaf size of 0.5 cm and a maceration time of 3 days. Under these conditions, maceration results were obtained with an absorbance value of 24,295 for the blue color with a wavelength of 409 and an absorbance value of 12,150 nm for the red color with a wavelength of 678 nm.

Abstract

The frequent occurrence of floods caused by overflows of river water indicates a lack of supervision of water level activities, even though the impact of the flood is very detrimental to the community. Therefore we need a business that can monitor and control water capacity, one form of business that can be made is by designing a device that can monitor and control the water level using sensors and microcontrollers. The way this tool works is as a means of detecting water level distances using an SRF 05 sensor by sending a signal to the Arduino uno microcontroller to process the data and then output from the LCD in the form of letters and numbers, the LED indicator which indicates the water level is a warning sign for this system. This system has three levels of water activity levels, namely at level 1 marked with a green LED then at level 2 marked with a blue LED then at level 3 marked with a red LED, the LED connected to the buzzer will provide a warning sign in the form of a siren/alarm that the water has been at the highest level and the relay has come alive with a red color. The design of an automated monitoring and control system for water level using sensors and microcontrollers has been successfully carried out. The purpose of this research is to design a tool that can monitor the water level in real time and is also based on a microcontroller. The calibration results show that the SRF 05 sensor has an average water level measuring instrument accuracy of 99.67% and has an average relative error of 0.33%. The results of this study indicate that the design of the tool that has been made has worked well as a monitoring and control system for water level using the Arduino Uno microcontroller.

Abstract

The batik industry is one of the producers of pollution that can damage natural ecosystems. Batik industrial wastewater contains a lot of pollutants such as conductivity, BOD, COD, TSS, TDS, oil, pH. and temperature which are not suitable for the environment. In this study, the reduction of COD, BOD. and the concentration of red naphthol dye in the batik industry wastewater which was adsorbed with activated carbon of candlenut shell was studied. Batik wastewater is taken from Ngentakrejo Village, Kapanewon Lendah, Kulon Progo Regency. Candlenut shell activated carbon was obtained from pyrolysis, sieved with a pore size of 20 mesh, 40 mesh and 60 mesh and activated with NaCl solution whose concentration varied from 1.0; 1.5; 2.0; 2.5. and 3.0 M for 16 hours. Activated carbon was applied to adsorb red naphthol on batik wastewater by varying its weight at 10; 20; 30; 40. and 50 mg. The results showed that the effectiveness of candlenut shell- activated carbon to reduce red naphthol was 12.29%, BOD 25.49% and COD 26.67%. The adsorption process with activated carbon is not recommended as a sole treatment for batik industrial wastewater.

Abstract

This study aims to determine the implementation of the Go Green school program in Indonesia. Data collection is carried out in several stages, namely searching for articles with the theme to be studied, and mapping topics. The step of analyzing the literature review method is by reading and re-exploring the points of thought on the same theme in several journals. to be able to add new ideas and opinions of the author regarding the topic to be raised. The author can also see the shortcomings of previous studies, so that the author can make improvements and more regular formulations. Energy security is an issue that has long been discussed by governments and even the global world. One of the government programs to maintain the resilience of the national country is the greening movement or what is often referred to as going green. The go green program is a government program that involves all elements of society including educational institutions in Indonesia. There are several elements in the go green program, in this study the author took three elements to be used as research material for the implementation of the go green program in schools, namely green transportation, green water, and green energy. The results of the study revealed that the implementation of the go green program in Indonesian Education institutions has not run optimally either in the school environment (adiwiyata school), or in the campus environment (Green campus). The low implementation of the go green program in schools is characterized by the low knowledge of teachers or principals related to knowledge based on the environment. At the university level, the implementation of the go green program is only found in a few universities and has not been comprehensive.
