Abstract

The air existence on the surface of the earth is one of the important factors for the survival of living things on it. Indonesia’s quality of ambient air has decreased and it is categorized as not good for sensitive groups. The biggest cause of air pollution comes from motor vehicles, of which 85% is from combustion in motorized vehicle engines. Trembesi is the most effective plant in adsorbing pollutant carbon in the air. Activated charcoal is the carbon that has better absorption of cations, anions and the molecules of organic and inorganic compounds. This study aims to create a pollutant filter equipment for CO and CO2 made from Trembesi leaves activated charcoal. This research was conducted by creating an air pollutant filter with 3 different types of adsorbent, namely adsorbent made from paper pulp, trembesi leaves extract adsorbent, and trembesi leaves activated charcoal adsorbent. The data collection used 2 types of vehicles with different year of release and engines. The measurement of pollutant concentration using a Gas Analyzer instrument tester with Korean Iyasaka AET-4000Q type. The result of this study showed that the best adsorbent is activated charcoal from trembesi leaves with 100% adsorption of CO and 36,29% adsorption of CO2 using 2018 Toyota Agya car Dual VVT-I engines with eco indicator technology, and for 1988 SE 1,3 Starlet car with a carburetor type engine successfully adsorb CO by 9,65% and 7,2% for CO2.

Abstract

Water is a basic human need. The use of water is very complex, among others, for drinking, cooking, bathing, washing, agriculture, fisheries, and so on. Coastal areas are often faced with the problem of limited water resources. In terms of quantity, coastal areas generally have abundant water, but it is often difficult to obtain water for various uses, due to inadequate quality. Limited water resources in coastal areas are related to the scarcity of fresh water that can be used as clean water. This study aims to desalinate brackish water into fresh water that can be used as clean water for sanitation hygiene needs. The process of desalinating brackish water into clean water uses the multimedia filtration method. Filtration is a process of separating solids from fluids (liquids or gases) that carry them using a porous medium or other porous material to remove as much of the suspended and colloidal fine solids as possible. The filtration media used in this study were activated carbon, silica sand, zeolite and gravel. These media are effective in reducing salinity and turbidity in brackish water.

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

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.
