Olive oils fraud currently becomes a major issue in food manufacturing. The current techniques such as Fourier transform infrared spectroscopy (FTIR), high-performance liquid chromatography (HPLC), and gas chromatography-mass spectrometry (GC-MS) cannot distinct the lard in plant-based fats. In this paper, silica optical fiber has been investigated experimentally to detect lard in olive oil with a concentration of 0–5% v/v. The silica optical fiber was connected to a laser source of 1550 nm and an InGaAs photodetector. The silica optical fiber with different fiber structures (single-mode fiber (SMF), multimode fiber (MMF), single-mode-multimode-single-mode fiber (SMS)) was utilized to evaluate the sensitivity of the sensor. The result showed that the SMS fiber structure is potential for the detection of lard adulteration in olive oils with a sensitivity of 1.1107 dBm/% ($v$/$v$). The proposed configuration of the SMS fiber structure offered a simple configuration for the rapid detection of lard adulteration in edible oils.

Volcanic ash produced by eruptions has been significantly dangerous towards aviation. The necessity of volcanic ash early warning system distribution is crucial to reduce casualties on aircraft accident. In this paper, some techniques of volcanic ash detection were compared to find the proper algorithm to visualize the volcanic ash distribution. The multispectral image was acquired from the geostationary satellite (Himawari −8 satellite) in specific time observation. The reference data were collected from the MODIS sensor in the Aqua satellite to monitor the volcanic ash distribution at the same time and place. The first method is to generate the value of brightness temperature differences (BTD) at $11 boldsymbol{mu} mathbf{m}$ and $12 boldsymbol{mu} mathbf{m}$ wavelengths. The second method is conducted by inserting $3.9 boldsymbol{mu} mathbf{m}$ information from the product of three-band volcanic ash known as (TVAP). The third method is a combination of the first and second method while the last method utilizes RGB composite color combination from several bands of Himawari −8. The reference data collected by MODIS Observation at 06.00 UTC. The BTD technique unable to detect low-intensity volcanic ash, while combining it with the TVAP method can increase the standard method performance. Based on expert judgment, BTD technique has a good performance for thick volcanic ash although unable to detect thin volcanic ash distribution. Three-band Volcanic Ash Product (TVAP) method could detect thick and thin volcanic ash. The combination of BTD and TVAP method has an excellent result to observe volcanic ash distribution, but the result tends to overestimate like TVAP distribution. RGB Methods from JMA Configuration have the same pattern and distribution of volcanic ash as MODIS observation. Based on the study results, BTD, TVAP, and RGB composite methods can produce good results compared to MODIS imagery for monitoring the volcanic ash distribution.

Cervical cancer was one of the most dangerous cancer suffered by women all over the world. One treatment method for cervical cancer was using radiotherapy. Cervical cancer can be treated using 2 types of radiotherapy such as brachytherapy and linac. The organ at Risk (OAR) were healthy organs which the most adjacent to the cervix namely bladder and rectum. The total dose received by OAR must be below dose tolerance. The purpose of this study was to determine the total dose received by bladder and rectum from a combination of brachytherapy and linac treatment (B-L) compared with combination linac and linac treatment (L-L). Prescribe dose for booster brachytherapy was 3x7 Gy and for booster, linac was 10x2 Gy. Evaluating the dose was by analyzing Dose Volume Histogram (DVH) bladder and rectum in 2cc volume (D2cc). The average total dose received by bladder from B-L was ($66.44pm 0.05$) Gy and from L-L was ($66.55pm 0.02$) Gy; the average total dose received by rectum from B-L was ($66.02pm 0.05$) Gy and from L-L was ($67.45pm 0.02$) Gy) respectively. Statistical analysis was carried out by Independent T-test, it is convinced that there was no significant difference ($mathbf{p} > 0.05$) in total dose received by bladder from both B-L and L-L treatment, while there was a significant difference ($mathbf{p} < 0.05$) in total dose received by rectum from both treatments. The total dose received by bladder and rectum from both B-L and L-L treatment remained in safety zone as those were still below the dose tolerance based on GEC-ESTRO recommendations (D2cc bladder<90 Gy and D2cc rectum<75 Gy).

A motor-tendon actuator is one of the widely used actuators in a soft robot that utilizes rope/wire connected to a motor. Soft tendon actuator is an alternative solution to the shortcomings of several other types of actuators such as pneumatic-network actuators, and shape memory alloy (SMA) actuators. This study presents the design process and manufacturing of motor-tendon actuators that can be used as an actuator for a starfish-like robot. Five soft motor-tendon actuators will be developed by varying the dimensions and composition of silicone rubber material. In the manufacturing process, a casting method is used to build four soft legs of the starfish-like robot. The tests for actuator bending are performed on the five developed motor-tendon actuators. Based on the test results, the bending angle of the proposed actuator is affected by the dimension of the soft leg, while the flexibility of the actuator is influenced by tendon thickness. Based on the composition of the soft leg material, the smaller the ratio of the composition of silicon rubber to the catalyst, the shorter the pot life material, and the faster curing time.

According to the Indonesian Traffic Police Center, in 2017 Indonesia ranks the top 4th countries in South East Asia which has a high number of road accidents. Many of the accidents, unfortunately, are caused by the drowsiness of car drivers. This indicates that human fatigue significantly affects the safety of traffic. To decrease the number of road accidents in Indonesia, this research proposes an alternative measurement tool and parameter to detect the drowsiness symptoms of car drivers. This research analyzes the usage of a wearable wristband blood pressure and heart rate monitor, attached to a car driver to detect drowsiness. The proposed measurement tool monitors all retrieved data to measure the fatigue condition of the driver. The main purpose of this research is to analyze the effectiveness of proposed wristband to collect the blood pressure and heart rate pattern for indicating drowsiness symptoms. This research concludes that car drivers' drowsiness can be detected by monitoring their heart rate and blood pressure using the proposed wristband. This research can be expanded in the future as a mitigation system to prevent car accidents caused by drivers' drowsiness. It can be expanded as an integrated Internet of Things system in a smart car that can alert a driver to take a rest when the system indicates that the driver is in a fatigue condition. When this integrated system has been developed well, the car accidents caused by driver drowsiness can be effectively prevented so that the number of car accident victims in Indonesia will be minimized.

The number of accidents on highways is not only caused by heavy traffic but also by human error and lack of means for road safety supports. To overcome these problems, VANET technologies are applied. VANET acts as a crucial role in serving a high level of protection from danger and convenience to the users of the roads. Each vehicle in VANET is equipped with wireless networking devices and electronic sensors through which they can detect surrounding conditions and send appropriate information such as an emergency warning to neighboring vehicles. In VANET, routing protocols have important roles as their responsibilities to make sure that data are delivered to destinations via best-chosen routes properly and timely. This study aims to evaluate routing protocols for road safety applications which have high reliability in facing various obstacles and the frequently broken links. This research was conducted using simulation method which utilized software tools as follows: Network Simulator 2 (NS2) as a network simulator, OpenStreetMap (OSM) as a vehicle road infrastructure map, and Simulation of Urban Mobility (SUMO) as a traffic simulator. The simulation ran under Linux Ubuntu operating system. We undertook the experiments using Ad hoc On-demand Multipath Distance Vector (AOMDV) in various traffic conditions and simulation parameters on Jakarta toll road with realistic vehicle mobility models. Packet Delivery Ratio (PDR) and End to End Delay (E2ED), which are commonly used as metrics for road safety applications, are measured to see the performance.

The collision experiment apparatuses that have currently developed can not able to assist students in understanding relation of physical parameters on the experiment that involves a collision restitution coefficient. This paper describes the development of the collision experiment apparatus for restitution coefficient determination based on free fall motion experiment. The system uses three couples of infra-red (IR) LEDs CQY99 as transmitter and photodiode sensors SFH 203FA as receiver while the data recording is driven by an SMD based Arduino Uno with an ATmega328 microcontroller. The sensors were mounted on a vertical transparent acrylic pipe in diameter of 100 mm, thickness of 5 mm and height of 1200 mm. The measuring used objects are spherical masses with varied diameter and type. The apparatus is installed on a 3-points configuration where the sensors are placed on three positions; sensor 1 is placed on the top, sensor 2 is in the middle, and sensor 3 at the bottom of the acrylic pipe. Sensor 1 and 2 can be adjusted according to the desired measuring distance. The work system of this apparatus is divided into three parts, that is: determining the acceleration of falling objects, application of the restitution coefficient, and helping students explore physical parameters related to the coefficient of restitution. The electronic circuit is designed with in two functions so that apparatus can calculate the period when the objects fall (t1) and bounce (t2). The surface of the apparatus is optimized to minimize air friction, so that the falling objects acceleration is equivalent to the Earth's gravity ($mathbf{g}=9.8 mathbf{m}/mathbf{s}^{2}$). To obtain the collision restitution coefficients (e) over the calculation, the bouncing surfaces were varied. The results of the collision experiment have shown the persistence of the collision restitution coefficient parameter, with the results of $mathbf{g}=9.79pm 0.0032 mathbf{m}/mathbf{s}^{2}, mathbf{u} < mathbf{v}, mathbf{p}_{2} < mathbf{p}_{1}, mathbf{I}=Delta mathbf{p}$, and as shown in the results, the value of e of a freely falling object is 0 < e < 1. Based on this result, the apparatus can be used as collision experiment tool at schools to help students in understanding the concept of free fall and collision restitution coefficients.
目前研制的碰撞实验装置不能帮助学生理解涉及碰撞恢复系数的实验中物理参数的关系。本文介绍了基于自由落体运动实验的碰撞恢复系数测定实验装置的研制。该系统使用三对红外(IR) led CQY99作为发射器，光电二极管传感器SFH 203FA作为接收器，而数据记录由基于SMD的Arduino Uno与ATmega328微控制器驱动。传感器安装在直径为100毫米，厚度为5毫米，高度为1200毫米的垂直透明丙烯酸管上。测量对象为不同直径和类型的球形质量。该设备安装在三点配置上，其中传感器放置在三个位置;传感器1位于顶部，传感器2位于中间，传感器3位于亚克力管底部。传感器1和2可以根据需要的测量距离进行调节。该装置的工作系统分为三个部分，分别是:确定落体加速度，恢复系数的应用，帮助学生探索与恢复系数相关的物理参数。电子电路设计有两种功能，装置可以计算物体下落的时间(t1)和反弹的时间(t2)。该装置的表面经过优化，使空气摩擦最小化，因此下落物体的加速度相当于地球的重力($mathbf{g}=9.8 mathbf{m}/mathbf{s}^{2}$)。为了获得计算过程中的碰撞恢复系数(e)，改变弹跳面。碰撞实验结果显示了碰撞恢复系数参数的持久性，结果为$mathbf{g}=9.79pm 0.0032 mathbf{m}/mathbf{s}^{2}， mathbf{u} < mathbf{v}， mathbf{p}_{2} < mathbf{p}_{1}， mathbf{I}=Delta mathbf{p}$，结果表明自由落体的e值为0 < e < 1。在此基础上，该装置可以作为学校的碰撞实验工具，帮助学生理解自由落体和碰撞恢复系数的概念。

Based on this result, the apparatus can be used as collision experiment tool at schools to help students in understanding the concept of free fall and collision restitution coefficients.","PeriodicalId":178365,"journal":{"name":"2018 3rd International Seminar on Sensors, Instrumentation, Measurement and Metrology (ISSIMM)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123251451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electromagnetic spectrum utilization for communication is increasing. Visible Light Communication (VLC) with a bandwidth up to 390 THz is expected to be an alternative technology for a wireless communication system. VLC comprises light emitting diodes (LEDs) on the transmitter and photodiode on the receiver side, where LEDs can be modulated at high speed so that allows high-speed wireless communication. One of the most potential modulation techniques for VLC is orthogonal frequency division multiplexing (OFDM), but the challenge is the output signal must be real and positive. Therefore OFDM needs to be modified, by adding DC-bias called direct current-biased optical OFDM (DCO-OFDM) or by signal clipping called asymmetrically clipped optical OFDM (ACO-OFDM). In this paper, we explain the implementation of DCO-OFDM and ACO-OFDM systems that have been realized in the Simulink System Generator. Verification is conducted by examining three main subsystems i.e. symbol mapping, OFDM, and reverse subsystem for 6 (six) requirements. The result shows DCO-OFDM system 100% meets all requirements, while ACO-OFDM is only able to meet 83.3% even though it does not affect the interpretation of signal received.
通信领域对电磁频谱的利用日益增加。带宽高达390太赫兹的可见光通信(VLC)有望成为无线通信系统的替代技术。VLC包括发射器端的发光二极管(led)和接收器端的光电二极管，其中led可以高速调制，从而实现高速无线通信。正交频分复用(OFDM)是VLC最有潜力的调制技术之一，但其难点在于输出信号必须是真实的和正的。因此，需要对OFDM进行改进，通过增加直流偏置称为直流偏置光OFDM (DCO-OFDM)或通过信号剪切称为非对称剪切光OFDM (ACO-OFDM)。本文介绍了在Simulink System Generator中实现的DCO-OFDM和ACO-OFDM系统的实现。验证是通过检查三个主要子系统，即符号映射、OFDM和反向子系统来进行的，以满足6(6)个需求。结果表明，DCO-OFDM系统100%满足所有要求，而ACO-OFDM系统在不影响接收信号解释的情况下，仅满足83.3%的要求。

Mobile robot path planning using artificial potential field approach is popular for its computational simplicity. However, the conventional artificial field potential approach possesses weakness when the robot is deployed into corridors environment. The approach makes the robot easily trapped in local minimum caused by long obstacles presence, thus makes the robot unable to get to the goal point. In this paper, a method for escaping local minimum in corridors scenario is proposed. The proposed method utilizes the omnidirectional sensor, which has the ability to sense 360 degrees field of view, to get information on obstacles which are surrounding the robot. This information is used for the robot to put a feasible temporary goal to guide the robot to detour the trap. Numerical experiment verified that the proposed method successfully generates a safe path and is able to escape the local minimum trap in corridors environment.
