Abstract

The construction of the factory will increase the amount of rainwater into runoff. This will cause an increase in flood inundation downstream. The purpose of this study is to plan an environmentally sound drainage channel in a shoe factory area of 16 hectares. The research location is in Lebasiu Village, Lebaksiu District. This research begins with conducting a hydrological analysis to obtain the most suitable rainfall intensity to be applied at the activity location. The maximum daily rainfall data comes from the Pakubeureum, Kadipaten, Jatiwangi and Pesayangan Tegal rain observation posts. The calculation results show that the selected rainfall intensity is the Van Breen Method with the Talbot Equation approach. The calculation of the planned discharge is carried out using the Rational Method of 123.89 m3/second. The calculation of the channel dimensions is based on the Manning Equation, where the channel width is 1.5 m and the depth is 1 m. The width and depth of the planned channel is 1.5 m and the width is 1.5. Infiltration wells are planned at PT. X is a form of corporate responsibility in environmental management and implementation of environmentally sound development. The results of the calculation of the required infiltration wells are 17 units. The infiltration wells will be built scattered around the factory by taking into account the location and suitability of the factory building design. Rainwater from each factory building will be channeled through gutters to each of these infiltration wells.

Abstract

The recording of the amount of electrical energy consumed by the public on postpaid electricity customers often experiences reading errors by officers. The contributing factor is the absence of occupants of the house when recording the amount of power used by the officer so that the officer records the use of electrical power based on the average previous use. Therefore, to find out the amount of electrical energy that is being used, a periodic electrical energy monitoring system is needed. This device is designed to support monitoring the use of electrical energy in household consumers. Arduino uno as a microcontroller based atmega28, current sensor and voltage sensor are supporting devices used as a monitoring system for the use of electrical energy that can provide information on electrical parameters such as voltage, current, power values, using the blynk application by utilizing the development of Internet of Think technology. IoT) so that the use of electrical power can be seen anytime and anywhere via the internet network. This tool has an average reading error value of 13.68% for current and 14.06% for power. Based on these data, this system is very suitable to be used as a monitoring of electric power consumption because the error generated is quite small.

Abstract

Wastewater from the outlet of hospital's Wastewater Treatment Plant (WWTP) is expected to be used for watering plants as an effort to water use efficiently. To answer this assumption, this research was carried out to examine the effects of hospital wastewater as a plant growth medium on the accumulation of pollutants in papaya (Carica papaya) leaves and fruit. Local papaya seeds were grown on the land around the hospital's WWTP and the plants were watered every day with wastewater. Plants were well cared for without adding other additives as fertilizer and their growth was observed. After 8 months of treatment, the fruits and leaves of plants were harvested and destructed using HNO3 and H2SO4 to measure the heavy metal content using the Atomic Absorption Spectrophotometer, Shimadzu A630. Results showed that when wastewater was used as a growth medium, metals Hg, Cd, and Pb were found to accumulate in papaya fruit with a concentration of 0.179; 0.582; and 2,327 mg/kg, while other metals such as Cr and As were not found to accumulate in papaya fruit. Metal accumulation was also found in papaya leaves with Hg content of 0.739 mg/kg and Cd of 0.582 mg/kg, while others metals Cr, Pb, and As were not found in the papaya leaves. These results indicate that the main source of heavy metal accumulation in papaya plants came from wastewater from the WWTP outlet containing heavy metals.

Abstract

Rainfall data is one of cause factor for flooding in some areas in Indonesia. An extreme rainfall event occurred in the end of 2020 until early 2021 have resulted a severe flooding in West Martapura District, Banjar Regency, South Kalimantan Province. As a tributary to Barito River, Martapura River experienced high water level that gave negative impact to the surrounding areas. HEC-RAS (Hydrologic Engineering Center's River Analysis System) 5.0.7 software combined with ArcGIS 10.8 were applied to model flooding spatially. Mononobe method was used to calculate rainfall intensity for 5-year, 50-year, and 100-year return periods. From the results of the flood modeling, the maximum flood water level elevation was obtained as deep as 3.8 m (5-year return period), 5.2 m (50-year return period), and 9.6 m (100-year return period) with a maximum flood discharge of 34.84 m3/s (5-year return period), 81.68 m3/s (50-year return period), and 142.64 m3/s (100-year return period), respectively.
