The major issue faced in restaurants and hotels is the quality of service provided by them especially ordering of food. Traditionally, it used to take a long time for food ordering as waiter used to note down orders, place it kitchen and the food was prepared. It also involved traditional pen and paper method and the process was time consuming. It also involved a lot of wastage of paper. Hence, we have designed the smart restaurant in which the orders will be placed paperless using Arduino UNO, TFT touch display connected to the kitchen chef directly using RF Transmitter. This acted as the transmitting side. At the receiving side, the order placed is seen on LCD screen and indication of buzzer with the help of RF Receiver and I2C Module confirmed the placing of order to kitchen. Hence, the workers focused on billing and other work process and provided better quality services. We found out that this method is useful in many ways like- It not only saved the wastage of paper but also reduced the burden on the waiters and workers to great extent. Time management was also done as more and more customers could be handled by taking their orders and provide quality service. This setup is quite practical on basis such that this system can be implemented for small startups hotels and restaurants. The investment cost is also one-time investment as it requires less maintenance. The only fact it requires is to update the system as per our convenience and new offers. It also required average skilled labor to operate. Hence, we can conclude that this system is eco-friendly as it saves the paper usage by directly giving the order to kitchen and chef. The second grasping factor is that the waiters can involve them in other process of billing and other process. Hence it promotes the multi-tasking process. Third factor covered is that fresh food can be served at a faster rate to the customers due to this table-kitchen friendly process. It even eliminates the errors occurred due to traditional methods and also involves constant upgradation and upliftment of the system helps in better customer end services.

AbstractIn fish farming activities there are a number of important things that must be considered, namely feeding and controlling the quality of the water in the pond such as water temperature, pH level and water clarity, because these elements are important for fish growth and life. Adjusting the time to feed the fish is also very important so that the fish can stay alive, if it is too late to feed the fish the fish can be stressed and eventually starve to death. Fish owners who have a fairly busy level of activity, will feel a little difficulty when leaving the house in a long time, because meeting the needs of fish and continuous monitoring is very time consuming. Thus, an automatic fish feeding device was developed which can be adjusted when feeding and measuring the feeding. In this study, Arduino Uno and Arduino Mega 2560 are the "brains" that control inputs, processes and outputs. Servo motor as a cover drive where fish feed is released. Water temperature sensors, pH sensors and water clarity sensors or TDS to monitor the state of the water. The output generated from the auto fish feeder has issued the feed in accordance with the set hours when testing, only the size of the feed will affect the amount of feed that comes out, as well as testing the temperature sensor, pH, and water clarity working properly.Keywords : Arduino, microcontroller, fish feeder, sensorDalam Kegiatan budidaya ikan ada beberapa hal penting yang harus diperhatikan yaitu pemberian pakan dan pengontrolan terhadap kualitas air yang ada dikolam seperti suhu air, kadar pH dan kejernihan air, karena unsur-tersebut penting bagi pertumbuhan dan kehidupan ikan. Penyesuaian waktu memberi makan ikan juga sangat penting agar ikan dapat tetap hidup, jika terlambat dalam memberi makan ikan maka ikan bisa stress dan akhirnya mati kelaparan. Pemilik ikan yang memiliki tingkat kesibukan yang cukup padat, akan merasakan sedikit kesulitan ketika akan meninggalkan rumah dalam waktu yang cukup lama, karena pemenuhan kebutuhan ikan dan pemantauan terus menerus sangat memakan waktu. Dengan demikian maka dikembangkanlah sebuah alat pemberi makan ikan otomatis yang dapat diatur waktu pemberian pakannya dan takaran pemberian pakannya. Pada penelitian ini menggunakan Arduino Uno dan Arduino Mega 2560 sebagai “otak” yang mengendalikan input, proses dan output. Motor servo sebagai penggerak penutup tempat keluarnya pakan ikan. Sensor suhu air, sensor pH dan sensor kejernihan air atau TDS untuk memantau keadaan air. Output yang dihasilkan dari auto fish feeder sudah mengeluarkan pakan sesuai dengan pengaturan jam yang sudah diatur ketika pengujian, hanya ukuran pakan akan mempengaruhi jumlah takaran pakan yang keluar, serta pengujian sensor suhu, pH, dan kejernihan air bekerja dengan baik.Kata Kunci : Arduino, mikrokontroller, fish feeder, sensor

The integration of greater functionalities into vehicles increases the complexity of car-controlling. Many research efforts are dedicated to designing car-controlling systems that allow users to instruct the car just to show it what it should do; however, for non-expert users, controlling the car with a remote or a switch is complicated. So, keeping this in mind, this paper presents an Arduino based car-controlling system that no longer requires manual control of the cars. Two main contributions are presented in this work. Firstly, we show that the car can be controlled with hand-gestures, according to the movement and position of the hand. The hand-gesture system works with an Arduino Nano, accelerometer, and radio-frequency (RF) transmitter. The accelerometer (attached with the hand-glove) senses the acceleration forces that are produced by the hand movement, and it will transfer the data to the Arduino Nano that is placed on hand glove. After receiving the data, Arduino Nano will convert it into different angle values in ranges of 0°–450° and send the data to the RF receiver of the Arduino Uno, which is placed on the car through the RF transmitter. Secondly, the proposed car system is to be controlled by an android based mobile-application with different modes (e.g., touch buttons mode, voice recognition mode). The mobile-application system is the extension of the hand-gesture system with the addition of Bluetooth module. In this case, whenever the user presses any of the touch buttons in the application, and/or gives voice commands, the corresponding signal is sent to the Arduino Uno. After receiving the signal, Arduino will check this against its predefined instructions for moving forward, backward, left, right, and brake; then it will send the command to the motor module to move the car in the corresponding direction. In addition, an automatic obstacle detection system is introduced to improve the safety measurements to avoid any hazards with the help of sensors placed at the front of the car. The proposed systems are designed as a lab-scale prototype to experimentally validate the efficiency, accuracy, and affordability of the systems. The experimental results prove that the proposed work has all in one capability (hand-gesture, touch buttons and voice-recognition with mobile-application, obstacle detection), is very easy to use, and can be easily assembled in a simple hardware circuit. We remark that the proposed systems can be implemented under real conditions at large-scale in the future, which will be useful in automobiles and robotics applications.

ABSTRACTThe effect of numerous plasma reative ion etch and physical milling processes on the electrical behavior of GaAs bulk substrates has been investigated by means of electric microwave absorption. It was seen that plasma treatments at quite low energies may significantly affect the electrical quality of the etched semiconductor. Predominantly physical plasma etchants (Ar) were seen to create significant damage at very low energies. Chemical processes (involving Cl or F), while somewhat less pernicious, also gave rise to electrical substrate damage, the effect greater for hydrogenic ambients. Whereas rapid thermal anneal treatments tend to worsen the electrical integrity, some substrates respond positively to long-time high temperature anneal steps.

After a long time was not heard to the public area, lately death penalty toward the criminal cases that classified as extraordinary crime are appear. The author discovers electronic article about the execution of the death penalty which is the prosecutor prepares to execute death penalty toward the drugs dealer. The president of Republic of Indonesia stated that it is necessary to give a deterrent effect to the convicted  criminal and keep the morality of Indonesian teenagers. According to my opinion, the author argues that it will be better and wiser if we discuss about renovating all of the Penitentiary in Indonesia than debating whether death penalty could be done in Indonesia or not, because it will be displeasure many parties, death penalty infringed the human rights of the convicted criminals and cause psychological burden to them, families, the executor of the death penalty, and other parties. Because if we have to improve the quality of the Penitentiary, if the function of Penitentiary for fostering moralily has been optimal or properly enough to the convicted criminals, Indonesia will be no longer need the death penalty option as sanction to the convicted crimanals including for the extraordinary crime (especially for drugs trafficking in our country). Penitentiary is one of the public services which aims for fostering the people that initially have bad habits (commited to the crime), so that they will have the awareness to change their bad attitude into the be better ones, will not harm others, and positively contributed to the society. Already Penitentiary’s conditions should be designed in such a way and as good as possible, so that the inmates feels like at their own home (like having a second home after his own home), and feel humaner to spend their days in the Penitentiary. The author believes that if the Penitentiary has been improved and optimized its function well, then the real purpose of Penitentiary will definitely achieved. As stated in Law Number 12 Year 1995 regarding to Penitentiary Article 2 which states "sanction system are organized in order to fostering the convicted criminals in order to be the real man, aware of their fault, improve themselves, and not to repeat the criminal act so that they can be friendly received by the community, can actively participated in the development of our country, and can socialize themselves as good citizen."Article 3 on this regulation also intensifies the function of Penitentiary "the function of Penitentiary is to prepare convicted criminals to be able to properly integrated to the society, so they can be accepted again as members of the public who are free and responsible ones."

Last time, management of equipment, maintenance and use of teaching equipment in lower secondary schools in Dien Bien district, Dien Bien province has been paid more attention, making important contributions to keeping sustainably, improve the quality of education in the district. Every year the lower secondary schools have been given funding and have plans to equip additional teaching equipment. Most lower secondary schools have full-time staff in charge of teaching equipment; with equipment storage rooms, cabinets are gradually added; laboratories and classrooms have been built more and more; have a system of records of teaching equipment management established; The work of inventorying and purifying teaching equipment periodically was also concerned. The movement of innovating teaching methods has made education managers and teachers more interested in using teaching equipment effectively. The positive management measures have caused many teachers to use teaching equipment as an integral part of the lesson, helping the quality of the lessons be increasingly improved to meet the requirements of changes. New teaching methods. Education administrators, teachers, teaching equipment staff are becoming more and more serious in teaching device management. However, the reality of teaching equipment management still reveals many limitations: The management of teaching equipment in schools is still administrative and ineffective. The equipment has no overall and detailed plans; The procurement of teaching equipment is not guaranteed in terms of quantity, lack of uniformity (some are redundant, some are lacking), quality is limited (durability, accuracy is not guaranteed, some new ones are not used); preservation still has many shortcomings; lack of specialized staff; lack of storage space or insufficient storage; lack of cabinets, prices, laboratories, subject classrooms; specially managing the use of teaching equipment is not tight; Many places teachers have not paid attention to use, ineffective use. The situation of “teaching vegetarianism” is still common, teaching equipment used is still movement, mostly used only in special cases such as competitions for good teachers, lectures or when there is a delegation check; There are many cases of information technology abuse in teaching. The effective use of teaching equipment oriented student capacity development is not much. The management of the use of teaching equipment oriented to develop student competencies in the current trend of Industry Revolution 4.0 is a matter of great concern to educational managers.Thus, the task of surveying the situation of managing the effective use of teaching equipment, finding subjective and objective reasons in order to propose measures to effectively manage the use of teaching equipment in the direction of developing students’ practical capacities and contributing to improving the quality of teaching in secondary schools in Dien Bien district, Dien Bien province is a very important and necessary task today.

The recent requirements by U.S.E.P.A. for dechlorination and biomonitoring have increased the importance of automatic control of effluent chlorination in wastewater treatment plants. Difficulties with the Ziegler-Nichols controller tuning procedure were reported at the Kyoto Workshop, 1990. Problems are caused by the noise of incomplete mixing, a long time constant, and the disturbances of changing flow and chlorine demand. The Astrom-Hagglund relay feedback procedure provides acceptable control while data is logged to determine the controller constants. Experiences in using the procedure in existing facilities (not redesigning the mixing point) and the quality of control are presented.

Chitosan is receiving increasing attention from the food industry for being a biodegradable, non-toxic, antimicrobial biopolymer able to extend the shelf life of, and preserve the quality of, fresh food. However, few studies have investigated the ability of chitosan-based coatings to allow the diffusion of bioactive compounds into the food matrix to improve its nutraceutical quality. This research is aimed at testing whether a hydrophilic molecule (tyrosol) could diffuse from the chitosan-tyrosol coating and cross the tomato peel. To this end, in vitro permeation tests using excised tomato peel and an in vivo application of chitosan-tyrosol coating on tomato fruit, followed by tyrosol quantification in intact fruit, peel and flesh during a seven-day storage at room temperature, were performed. Both approaches demonstrated the ability of tyrosol to permeate across the fruit peel. Along with a decreased tyrosol content in the peel, its concentration within the flesh was increased, indicating an active transfer of tyrosol into this tissue. This finding, together with the maintenance of constant tyrosol levels during the seven-day storage period, is very promising for the use of chitosan formulations to produce functional tomato fruit.
