<![CDATA[Abstract— In maintaining the quality of aviation fuel, before being marketed, the aviation fuel must pass through the filtering stage using a filter. The use of filters must be monitored for efficiency by using a PDG (pressure different gauge) instrument. PDG is a measuring device that is equipped with a switch and will be a disconnect when the PDG needle shows a number above 15 psi. However, filter monitoring is only done by looking at the PDG installed on each filter and the switches on the PDG have not been used at all. From this problem, the author conducted research out by designing and building a tool that can monitor switches on the PDG and provide SMS notifications. In its design, the device uses Arduino Uno as a microcontroller with a 12VDC power supply. This device is equipped with GSM SIM900A which functions to send SMS. Based on research, the highest current consumption is 0.18 A and the smallest is 0.11 A. The average time for sending an SMS is 7 seconds. Based on testing the tool can work as expected. With the design and construction of this device, it is expected to help PT. Pertamina DPPU Ngurah Rai to monitoring the performance of filters in realtime so that the replacement of filter elements can be done in a timely manner and maintain the marketed aviation has good quality.]]>

<![CDATA[In communication systems using microwave waves (microwave links), the presence of noise and multipath fading can reduce and reduce the performance of communication systems. Microwave propagation is influenced by several things in the reception system besides having to LOS (Line of Sight) there is a reflected signal from the surface that is causing interference (multipath signal). By using the diversity maximal ratio combining technique on systems affected by noise and fading, it is used through BER (Bit Error Rate) analysis. The use of research simulations to determine the improvement of the system at the recipient by comparing before and after using the maximal ratio combining technique]]>

<![CDATA[Intisari— Perkembangan teknologi khususnya dibidang robotika saat ini sangat pesat, Salah satu bentuk aplikasi dari teknologi robotika yang erat kaitannya dengan sistem kontrol adalah wheel mobile robot. Beberapa metode dapat dilakukan untuk mendistribusikan gas alam salah satunya dengan pipa. Distribusi gas alam dengan menggunakan pipa sering mengalami kendala kebocoran yang disebabkan usia dari pipa distribusi yang sudah cukup tua. Untuk mempermudah pemantauan pipa gas yang berada di bawah tanah digunakan robot 6 WD (wheel drive) yang memiliki 6 roda dan penggerak pada setiap rodanya untuk mengatasi medan yang berat. Pergerakan dari robot 6 WD mengacu pada sensor ultrasonik SRF HC-SR04, metode ini dinamakan wall following. Sensor gas tipe TGS dari figaro dimanfaatkan untuk mengetahui adanya kebocoran gas pada pipa atau tidak. Selain itu, robot ini juga dilengkapi dengan kamera untuk mengirim gambar kerusakan pipa pada user agar dapat segera dilakukan perbaikan. Arduino Mega 2560 digunakan sebagai otak pada robot 6 WD yang bertugas untuk mengolah data yang masuk dan memberikan instruksi pada robot 6WD. Pengiriman data dari robot 6 WD pada pengguna meliputi, data sensor gas, data sensor kompas, data sensor jarak dan gambar kerusakan pada pipa. Seluruh data dapat dilihat pada GCS (Ground Control Station). [TRUNITIN CHECK 20%, 26042017]]]>

<![CDATA[Global warming is contributed by human activities in many sectors. The sector that contributes significantly to generating carbon emissions is transportation sector. An effort to reduce carbon emissions is by utilizing PV panels on vehicle’s body surface. This paper reviews the development of vehicle-mounted PV panels around the world. The review covers technical specifications, manufacturer, and function of the PV panel on the vehicle. The objective is to get insight on the current development of vehicle with PV panels. The information presented in this paper is expected to provide updates for stakeholders in the field of renewable energy and land transportation in Indonesia. Also, this information can be used as a reference for further research on vehicle with PV panels both in Indonesia or elsewhere that are developing future environmentally-friendly vehicle. The result is a database consists of 948 vehicle which has solar PV around the body of the vehicle. 936 vehicles or about 99% were made for solar car race and only 1% for commercial and prototype. The solar PV system serves as a main or auxiliary power supply of the vehicle depending on whether they are hybrid or fully electric cars.]]>

<![CDATA[Domestic violence is the most common case in the community. Women and children are victims of domestic violence. In Denpasar, Indonesia, currently, data collection system of victims of domestic violence (KDRT) is conducted by the Women's Empowerment and Child Protection Agency. It is still has some limitations because it is operating manually. Through this web-based data collection system of domestic violence, a complaint report on domestic violence can be done digitally so it does not need to report manually to the authorities. In this system, the victims will be given freedom to show or hide their identity. This system receives input filled form of violent reports; next, the complaints report can be known by others (not admin) anonymously. After the complaint report get into in the system, it will be done the next process which is verification. The results of the verification process will determine the validity of complaint reports. After passing the verification process, report data will be recorded in the system and will be done the formulation of follow-up to the action of the case by the legislation authorities.]]>

<![CDATA[Abstract— The exact estimation of the number of colonies or Colony Forming Units (CFUs) is frequently used in microbiology research, particularly in the field of bacteria. The number of colonies that develop per gram or milliliter of sample is estimated by multiplying the number of plates, the dilution factor, and the volume used [1]. Counting the number of bacterial colonies can be used to determine a bacterium's growth rate. The cup count method is commonly used to accomplish this manually. An instrument called a colony counter can help with colony counting utilizing the cup count method. This technology works by using a pen connected to a counter to mark the colonies that have been counted. However, because the colony size is tiny and the number of colonies counted is huge, this can lead to inaccuracies, and the same difficulties can happen with manual colony computations. Digital image processing technology has been extensively developed for use in a variety of fields. Researchers had previously undertaken a similar study that attempted to count bacterial colonies and had a 94 percent accuracy rate, but some colonies were not spotted because they were filtered during preprocessing, so they looked into it further.

<![CDATA[Organic light-emitting diodes (OLEDs) have emerged as one of the most important generallighting technologies of the future. The current state-of-the-art OLED utilizes various differentlayers which function separately as carriers transport, carriers and excitons blocker, and emittinglayer. The emission layer of the OLED is normally formed by a host-guest system obtained byco-evaporating a small amount of guest molecule in the matrix of host material. It is generallyaccepted that in a host-guest system, concentration quenching is caused by molecules aggregation.As concentration of guest molecule increases, a drop in quantum efficiency is followed by a redshiftin the emission spectrum, characteristics of aggregate state. Here we show that concentrationquenching is also caused by another Förster-type interaction. We investigate this Förster-typeexciton quenching process in various organic molecules and its effect to the exciton diffusion.]]>
