Abstract

Waste is waste that comes from the process of making or using an industrial or domestic product. The waste generated is in the form of liquid and solid. Waste is also an unused waste material that has a negative impact on society if it is not managed properly. Liquid waste or waste is water that cannot be used anymore and can have a negative impact on humans and the environment. Multi Soil Layering (MSL) system is a liquid waste treatment method that utilizes the ability of the soil as the main medium in removing pollutants in liquid waste. The purpose of this study was to determine how to treat restaurant liquid waste using the Multi Soil Layering (MSL) method for the parameters of pH, BOD, COD, and TSS. Based on research, the Multi Soil Layering (MSL) reactor is effective in improving pH values ​​and reducing COD and TSS so that restaurant wastewater does not pollute the environment and can prevent negative impacts caused by restaurant liquid waste.

Abstract

Stasiun Pengisian Bahan Bakar Umum (SPBU) merupakan suatu tempat bagi masyarakat untuk mengisi bahan bakar kendaraan bermotor. Kegiatan di sekitar jalan raya tidaklah lepas dari kehadiran alat transportasi seperti kendaraan bermotor. Kepemilikan dari kendaraan bermotor semakin meningkat setiap harinya baik itu milik pribadi ataupun kendaraan umum sehingga menimbulkan kebisingan pada daerah tersebut. Kebisingan merupakan suatu bunyi atau suara yang tidak diharapkan dari suatu usaha maupun suatu aktivitas dengan rentang waktu pemaparan yang tertentu sehingga dapat menyebabkan berbagai gangguan pada kesehatan tubuh manusia serta terganggunya kenyamanan akan lingkungan hidup. Oleh karena itu kebisingan perlu direduksi atau dimitigasi dampaknya. Salah satu Metode yang dapat digunakan untuk mengurangi tingkat kebisingan yaitu menggunakan Metode MEAD. Metode ini berkaitan dengan menganalisis, mengevaluasi dan mendesain sistem kerja dalam organisasi sehingga dapat menjadi lebih efektif serta efisien. Dari hasil penelitian di SPBU Lingke Banda Aceh didapati bahwa persebaran tingkat intensitas kebisingan yang diuji pada titik 1 hingga 7 diperoleh dengan rata-rata masih dibawah 85 dBA. Menurut Keputusan Mentri Lingkungan Hidup No.40 tahun 2017, kebisingan dibawah 85 dBA ini masih berada di bawah ambang baku mutu.

Abstract

Following the regulation of the Indonesian Government, every Mining company has an obligation to do reclamation for mining areas that had been exploited. One of the reclamation stages is re-vegetation to plant the exploited mine area with cover crops. Cover crop monitoring commonly is taken by direct assessment of plants growth. However, this approach is ineffective and also expensive which is proportional to the large reclamation area. The objective of this research is to apply remote sensing methods to monitor cover crop growth at Siltstone Quarry of PT Aroma Cipta Anugrahtama, in Lhoknga subdistrict, Aceh Besar. The monitoring was conducted using Sentinel-2 satellite imagery data by computing the Normalized Difference Vegetation Index (NDVI). The analysis was done in a time series from the year 2019 to 2022 using the Google Earth Engine (GEE) cloud platform. The result shows that the NDVI value is varied from 0 to 0,8 which is classified into no vegetation to high vegetation area. Based on spatial distribution of NDVI values, can be observed that the northern area has higher uniform NDVI value compared to the southern area which is more mixed. This indicates the southern part has been exploited earlier. Overall the re-vegetation successful rate for reclamation zone before 2019, 2019, 2020, 2021 and 2022 are 96%, 99,5%, 70,6%, 36,6% and 6,2%.

Abstract

Lemna minor plant have the ability to reduce pollutant levels in Landfill leachate. The use of Lemna minor in leachate treatment was considered effective in degrading Cd and COD pollutants. The objective of this study was to determine the effectiveness and absorption rate of Lemna minor in degrading heavy metal Cd and reducing COD levels in Gampong Jawa Landfill leachate. This study used the phytoremediation method on a laboratory scale, and the leachate sampling method used the grab sampling technique. In testing both parameters, two types of test variations were carried out. First, in Reactor I, it was carried out without using an aerator, and in Reactor II, the test was carried out with the addition of an aerator. For duration, the variations of retention time were used are the third, sixth, ninth, and 12th days. The weight of the Lemna minor were used in each reactor was 35 grams for a leachate volume of 5 Liters. The results showed that Lemna minor was able to reduce pollutant levels in the Gampong Jawa Landfill leachate with the most optimal proportion of 15.92% for the heavy metal Cd, and 94.68% for the organic pollutant COD. Treatment on the 12th day for tests carried out in reactors that have an aeration system was the most effective variation in reducing the levels of Cd and COD parameters.

Abstract

Nabi Muhammad SAW menggunakan hanya 1 mudd air (sekitar dua pertiga liter) untuk berwudu. Penelitian ini bertujuan untuk mengetahui efisiensi penggunaan air wudu dengan sistem wudu yang berbeda yaitu sistem keran dan sistem kolam, preferensi jemaah Masjid Darul Falah (sistem keran) dan Masjid Haji Keuchik Leumik (sistem kolam) Kota Banda Aceh terhadap sistem wudu. Hasilnya ternyata sistem wudu kolam lebih menghemat air dibandingkan sistem keran, volume wudu rata-rata per individu dengan sistem keran adalah 10,05 l/org dan sistem kolam 3,35 l/org. Dari kedua sistem wudu, mayoritas responden memilih sistem kolam (60%). Diperlukan strategi ke depan agar sistem yang lebih menghemat air bisa lebih dipilih oleh jamaah selain untuk mengikuti tuntunan dalam Islam tapi juga untuk efisiensi penggunaan air.

Abstract

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.

Abstract

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.
