Abstract

Telah dilakukan pengembangan sistem instrumentasi untuk mengidentifikasi aktifitas jantung pada mencit. Mencit (Mus musculus) adalah anggota muridae (tikus-tikusan) yang berukuran kecil. Mencit banyak digunakan oleh dokter , farmasi atau aktifitas praktikum lab pada universitas. Mencit digunakan sebagai hewan percobaan. Hewan mencit sangat berkesan dalam dunia obat-obatan. Yang sering di ketahui bahwa setiap obat yang digunakan dalam dunia kesehatan hari ini pastilah pernah melalui masa pengujian preklinik. Biasanya untuk mengidentifikasi bagaimana pengaruh obat dan reaksi yang terjadi  harus membedah dan membunuh hewan tersebut. Studi yang dilakukan pada penelitian ini adalah bagaimana membuat suatu sistem alat untuk mengamati aktifikas jantung dengan menggunakan Elektrokardiogram (EKG) dengan keluaran diharapkan mengidentifikasi tanpa harus membunuh. Untuk menampilkan aktifitas tersebut yaitu menggunakan alat Open Brain Computer Interface (BCI) dipasang dengan elektroda, kemudian elektroda tersebut dipasang dibagian jantung dari tikus tersebut. Open BCI yang dipakai adalah Open BCI Ganglion dengan 4 channel. Biasanya open BCI ganglion digunakan sebagai pengukuran dengan subjek manusia, tetapi studi ini mengimplementasikan open BCI untuk pengukuran hewan yaitu mencit.  Analisa sinyal dilakukan dengan cara mengamati gelombang EKG dengan fitur interval RR, lebar QRS pada EKG.

Abstract

Electrocardiography (ECG) has been instrumental for early detection of cardiovascular anomalies. In this research, we successfully prototyped and evaluated the performance of a novel dry electrode as ECG sensor. Copper was selected as dry electrode material due to its good balance between conductivity and affordability. Polyaniline was used as a conductive coating to facilitate the conversion of ionic currents from the human body into electrical currents in electronic circuits. The coating was carried out via electrodeposition technique. Optimal electrodeposition time of 20 min using acetic acid as a dopant was established. This yields in the dry electrode with comparable performance to the certified wet electrode currently available in the market, shown by PQRST signal correlation between dry electrodes (this study) and the wet electrode (benchmark) which is close to zero. The dry electrode prototyped in this study is characterized to have a conductivity of 7 x 10 -4 S/mm, a resistance of 10 Ω, capacitive reactance of 140 Ω, and excellent signal stability showing a value of 256.5 μV consistently for 2 hours.

Abstract

Water is an essential need for humans and consumed as drinking water after fulfilling the health requirement in the Republic of Indonesia Minister of Health Regulation No.492/Menkes/Per/IV/2010. Due to the increasing demand, there are currently many refilled drinking water stores as an economical and practical alternative way to people. However, their safety still needs to be tested in the laboratory. This condition is impractical so that it needs a portable measuring instrument especially based on the TDS sensor that can measure the total dissolved solids (TDS) and electrical conductivity (EC) at once, which determines the taste and safety of the water. TDS sensor calibration at 80.5 to 966 ppm shows a 93.4% accuracy; 99.8% precision and 1.3 ppm hysteresis. In comparison, EC calibration at 161 to 1932 microsiemens/cm produces an average of 82.3% accuracy, 97.1% precision, and 1.0 microsiemens/cm hysteresis. This prototype is then employed to measure the water sample and determine its safety to consume and observed a decreasing trend of TDS and EC (194.1 ppm and 388.2 microsiemens/cm) as compared to the water spring sample (20.2 ppm and 402.3 microsiemens/cm). The prototype also has a Bluetooth module that enabling the remote observation on a cell phone without the presence of a telephone network.

Abstract

Semi-Automatic Image Segmentation for Volumetric Visualization of Pelvis CT Scan-Images. The current development of computerized tomography (CT) has enable us to obtain cross sectional image using multi slicing techniques in an order of few seconds. The obtained images represent several tissue structures on cross section slice being imaged. One challenge to help diagnosis using CT images is extracting an anatomic structure of interest using a method of image segmentation and volumetric visualization with the assistance of computers. In case of volumetric visualization of pelvis bones extracted from multi-slice CT images, whole images which are containing part of pelvis bone structures must be segmented. In this research, an image segmentation technique based on active contour is implemented for semi-automatic multi slice image segmentation. Image segmentation steps are initialized with a define model of 2D curve on the first slice image manually. Next, its model curve is deformed to reach the final result of 2D curve that fits to boundary edges of pelvis bone image. The final result of 2D curve on previous slice image was used as an initialization model of 2D curve on the next slice images. This process will continue until the final slice image. This segmentation method was compared with the segmentation method based on threshold from homogenous intensity distribution and manual segmentation method. Quantitative analysis from the results of segmentation on each slice and qualitative analysis on the representation of volumetric visualization are performed in this research.

Abstract

Technological developments, especially in the IoT (Internet of Things), play a significant role in various fields. In addition to achieving a modern and efficient work environment, IoT can also play a role in the security sector, which has now become a significant need. One of the roles of IoT in the security sector is that it can be applied to calibrated TMWE (Measuring, Dosing, Weighing, and Equipment). So that it can guarantee the correctness of the measurement results from the TMWE, continuous monitoring can be carried out so that fraud does not occur. One of the innovations in this regard is the smart seal. The use of smart seals is prioritized for fixed TMWE, which is vulnerable to theft and breaches. This system is designed based on IoT, which is integrated with cloud services and GPS systems that allow the use of web-based applications for online monitoring of seal conditions by users. Data from the seal will be sent to the server via wifi network and stored in a database, to be displayed in web service with a user, admin, and signer access. In addition to providing information to users about the seal’s location, the use of the GPS also aims to make it easier for admins to detect the seal’s location in the event of a violation.

Abstract

Pengontrol kepekatan larutan nutrisi adalah alat yang digunakan untuk mengkondisikan kepekatan larutan nutrisi agar tetap berada pada set point ruang lingkup pertanian. Pengontrol kepekatan larutan nutrisi digunakan pada sistem hidroponik khususnya metode Nutrient Film Technique (NFT). Dalam hal ini pengontrolan dilakukan pada kepekatan nutrisi pada reservoir yang digunakan sebagai media air yang sudah tercampur dengan nutrisi yang kemudian dialirkan pada tumbuhan. Di masa depan, alat ini diharapkan bisa membantu petani hidroponik agar dapat melakukan pengontrolan secara otomatis sehingga mampu untuk memperkecil peluang terjadinya gagal panen. Pengontrolan ini dilakukan dengan menggunakan sensor TDS (Total Dissolved Solid) yang digunakan untuk mengukur kepekatan suatu larutan. Dalam penelitian ini, pengontrolan kepekatan larutan nutrisi difokuskan untuk kebutuhan nutrisi tanaman tomat. Dari hasil uji kalibrasi yang dilakukan pada tiga titik uji pengukuran 96,2 ppm, 500 ppm, dan 1000 ppm besar nilai kesalahan secara berturut turut adalah 10%, 7%, dan 4%. Ketika prototipe sudah dipasang pada instalasi hidroponik NFT untuk menambah kepekatan sebesar 180 ppm perbandingan antara larutan nutrisi dengan reservoir campuran adalah 1 : 200. Pada pengujian debit pompa, besar debit pompa yang sudah dipasang 3,33 mL/s. Kemudian, ketika dilakukan pengujian pengontrolan dari jarak jauh dapat dipastikan bahwa penunjukkan kepekatan nutrisi dari jarak 0 km sama 8,1 km adalah sama.

Abstract

Cardiovascular diseases are the world’s leading cause of death with significant death rates caused by abnormalities in vessels such as aneurysms and stenosis. These conditions can potentially cause blockage and thinning of vessels which may lead to heart attack, stroke, and bleedings. Recently, computational simulation methods are frequently used in blood flow analysis. These methods are frequently used in vascular fluid dynamics analysis which relate to the origin of a disease, efficacy prediction in installation of therapeutic instruments and complements the in vitro studies. This article presents an example of a simple vascular simulation to study the effect of blood flow with respect to vascular wall displacement. Furthermore, this research shows the importance of formal CFD pre-processing such as mesh independence testing which influences the simlation accuracy as well as vascular flow prediction and its effects on vascular wall displacement. In this research, it is concluded that the number of mesh elements affects the accuracy of vascular wall shear stress (WSS) calculations with average WSS difference of 0.8 Pa with no significant difference in wall displacement values. An average WSS of 1.95 Pa and a wall displacement of 5.7 µm are obtained from the blood flow simulation in this study.
