2023-07-16T11:58:07+00:00

D.I. Reje Guru is an open system irrigation network located in Bukit District, Bener Meriah Regency, Aceh Province. Various problems were identified such as cracked lining and wild vegetation around the network. These issues have impact on water losses along the channels’ conveyances through evaporation, seepage, operational factors and leakage. The input – output discharge measurement is used to determine the water loss and the value of the efficiency of water distribution in the Irrigation network. In addition, the evaporation and seepage loss are also calculated to find out the percentage of the loss from these two factors. The results shown that the maximum and minimum loss is from BS3RG and BS4RG which are 0,027 m³/sec and 0,004 m³/sec, respectively. The values are correlated to the efficiency values which are the highest 84,23% from BS4RG and 36,908% from BS3RG. It is confirmed that the two factors of evaporation and seepage are not the significant factor to the conveyance water loss.

PENGGUNAAN PROTOTIPE KERAN WUDU OTOMATIS MENGGUNAKAN ARDUINO DAN MULTI SENSOR UNTUK KONSERVASI AIR

2023-07-17T09:54:31+00:00

Generally, the volume of water used for wudu varies for each person, with an average of 6 liters per person per time, depending on the habit of how one opens the tap and the water flow rate. However, according to hadith, the Prophet Muhammad Saw performed wudu using only one mud of water (625 milliliters). Water conservation during wudu can be achieved by reducing the amount of water discharged from the tap. In this study, an automatic wudu faucet prototype was designed, equipped with infrared sensors, a buzzer, ultrasonic technology, and controlled by an Arduino Uno microcontroller. In this system, the faucet will only open when there is an object or a hand/foot beneath it and will close when no object is detected anymore. Additionally, the system will produce a sound indicating that an object is approaching within a distance of 10 cm. This prototype is able to increase the efficiency of water usage during wudu by 67%. The average water usage for wudu using a manual faucet by the subjects was found to be 4.86 liters per person per time. After using the automatic wudu faucet prototype, the average water usage was reduced to 1.624 liters per person per time. Water conservation, even in small activities like wudu, can contribute to preserving water resources and ensuring their availability on Earth.

ANALYSIS OF FIRE PROTECTION SYSTEM ON THE MULTIFUNCTIONAL LABORATORY BUILDING OF AR-RANIRY STATE ISLAMIC UNIVERSITY BANDA ACEH INDONESIA

2023-07-16T11:57:49+00:00

Fire can occur if three main elements are met, namely heat, oxygen, and fuel or it is called the fire triangle. Risks arising from fire incidents can be minimized by a fire protection system and the reliability of building safety systems. To ensure that the two systems run optimally, an evaluation and examination are needed on the existing conditions based on the applicable safety technical standards. This study aims to determine the existing condition of the applied fire protection system and to determine the reliability of the building safety system in the Ar-Raniry Multifunctional Laboratory Building. This research was conducted using a quantitative descriptive method. Research data collection was carried out using observation and interview methods. The observation method for existing conditions was carried out using a checklist compiled based on the Indonesian Minister Public Works’ Regulation Number 26/PRT/M/2008 of 2008 for fire protection systems and fire protection code from the National Standardization Agency of Indonesia Number Pd-T-11-2005-C on the reliability of building safety systems. The results show that the fire protection system in the UIN Ar-Raniry Multifunction Laboratory building was in the Enough category, with a value of 3.25. This is due to the absence of several active fire protection instruments such as fire extinguishers, sprinklers, and hydrants. Addionally, from the results of the reliability of the building safety system for the UIN Ar-Raniry Multifunction Laboratory building, it is in the Enough category with a value of 63.02. This is caused by the absence of emergency lighting and water sources as a source of hydrant water.

PERENCANAAN SUMUR RESAPAN PADA GAMPONG LAMTEH BANDA ACEH

2023-07-30T12:03:50+00:00

Changes in land use cause to reduced water absorption. Aceh Province is one of the areas that does not yet have technical regulations that have been implemented in terms of increasing water infiltration. This is one of the causes of not optimal flood handling. In urban areas, for example in the capital of Aceh Province, namely Banda Aceh, floods still occur frequently when there is high rainfall intensity and long duration of rain. One of the villages that experienced inundation was Gampong Lamteh, Ulee Kareng District, Banda Aceh. One solution to this problem is the construction of environmentally sound drainage in the form of infiltration wells. The existing drainage channels in Gampong Lamteh Banda Aceh are currently only located at a few points to drain excess water into water bodies while the rest are still ground canals. The cause of inundation is due to the unavailability of rainwater infiltration sites. After planning, the infiltration discharge value obtained by the infiltration wells is 0.000006594 m³/second and the total storage volume is 70,650 m³ and the design of the infiltration wells is planned in the form of a circle with a well height of 3 m, radius 0.5 m radius and the planned number of wells is 30 wells.
