Abstract

In this investigation, the currents in Eastern Indonesian region are simulated by using the equations of motion (Navier-Stokes Equation). These equations are solved by the Hamburg Shelf Ocean Model (HAMSOM). Two cases are carried out, i.e. in the condition of west monsoon (February 1994) and east monsoon (August 1994). The simulation results are discussed for surface current, currents at 100-200 m, and the bottom current. In general, the results obtained agrees well with the work of Wyrtki, 1961 and Ahmat et al., 1995, but less with the work of Gordon and McClean, 1999.

Abstract

The mission to observe the Sea Surface Salinity (SSS) from the space is not really new because it has been started from long time ago. The first mission was the Skylab which used a 1.4 GHz microwave radiometer in 1970’s. But this mission is still not as comprehensive as other missions which observe such as Sea Surface Temperature (SST), Sea Surface Height (SSH), Ocean Color, and so on. Realizing the importance of SSS distribution in the ocean and its influences to the Earth’s climate system has motivated the scientists to develop a new technique in observing the SSS from space and lead a mission called the SMOS mission which was launched in November 2, 2011. Besides observing the SSS, this mission observes the Soil Moisture as well. The Soil Moisture and Ocean Salinity (SMOS) mission aims to obtain global and regular measurements on the soil moisture and the ocean salinity. These measurements are essential for climate and hydrological models, among other purposes. SMOS payload is a L band (21 cm, 1.4 GHz) 2D interferometric radiometer on a generic Proteus platform. The mission lifetime is at least 3 years (0.5 for commissioning and 2.5 for normal operation) + 2 years (extended operation) + 10 years for the post-mission processing. Raw physical data, level 1 and level 2 products will be produced by the PDPC (SMOS Payload Data and Processing Centre). It is an ESA center located in Villafranca (Spain) and operated under the responsibility of ESA. The SMOS Ocean Salinity objective is accuracy better than 0.1 psu, with 10 days to monthly grid scale (200 km).

Abstract

Abstract : Islamic tradition and science have been going through a long history. The Islamic world centred in the Middle East was once a centre of knowledge that was marked by the birth of prominent Islamic scientists and the development of knowledge and technology. Islamic tradition and science are naturally integrated. For instance, it can be seen from the necessity of Earth science knowledge in Islamic ritual practising. However, the decline of Muslim civilization also had an impact on science, including in the field of geoscience. This paper seeks to explain the relationship between the Tafsir al-Qur’an and geoscience, among of them are about the creation of the earth, the structure of the earth, as well as tectonic and volcanism, wherein al-Qur’an they are delivered in many parts.Abstrak : Tradisi Islam dan sains mengalami sejarah yang panjang. Dunia Islam yang berpusat di Timur Tengah pernah menjadi pusat pengetahuan yang ditandai dengan lahirnya ilmuan Islam terkemuka dan pengembangan pengetahuan dan teknologi. Tradisi Islam dan sains terintegrasi secara alamiah termasuk integrasi antara ilmu kebumian dan peribadatan ummat Islam. Namun, kemunduran Islam juga berdampak pada kemunduran di bidang sains, termasuk pada bidang kebumian. Makalah ini berupaya memaparkan hubungan antara tafsir-tafsir Al-Quran dengan ilmu kebumian, diantaranya penciptaan bumi, struktur bumi, serta tetonika dan vulkanisme, dimana hal tersebut telah disebutkan di beberapa bagian di dalam Al-Quran.

Abstract

Activities along the Krueng Aceh river such as port activities, fisheries, ship breeding, tourist attractions, market activities and settlements cause a lot of domestic waste in the environment around the river and affect river clarity and increase the concentration of turbidity. High turbidity in rivers can affect the entry of light into the waters because light has an important role in the photosynthesis process. The method of monitoring water quality can be done by remote sensing because it has several advantages such as being able to carry out measurements on a larger scale for a long time, relatively quickly, and reducing the amount of costs incurred. Monitoring the Krueng Aceh River is carried out using remote sensing technology using Sentinel-2 imagery. This study aims to obtain the value of the distribution of turbidity by analyzing satellite imagery and its correlation with rainfall, and to determine the value of the distribution of turbidity, Total Suspended Solid (TSS), Total Dissolved Solid (TDS), and Power of Hydrogen (pH) in the Krueng Aceh River. The results showed that sentinel-2 image analysis got the lowest turbidity on September 6, 2021, which was -0.992424, and the highest on October 5, 2019 which was 0.248641. The distribution of water quality is known to have the highest turbidity concentration obtained at sampling location point 1, which was 107.9 NTU. The highest concentration of TSS was found at sampling locations 1, 4, and 7, which was 400 mg/l. The highest TDS concentration was found at point location 1, which was 1,413 mg/l. The pH concentration at the Krueng Aceh River sampling location has met the quality standards set in PP No. 82 of 2021

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.
