Motivated by the hype around driverless cars and the challenges of the sensor integration and data processing, this paper presents a model for using a XBox One Microsoft Kinect stereo camera as sensor for mapping the surroundings. Today, the recognition of the environment of the car is mostly done by a mix of sensors like LiDAR, RADAR and cameras. In the case of the outdoor delivery challenge Robotour 2016 with model cars in scale 1:5, it is our goal to solve the task with one camera only. To this end, a three-stage approach was developed. The test results show that our approach can detect and locate objects at a range of up to eight meters in order to incorporate them as barriers in the navigation process.

Clothesline that is used in the community is still in the form of a manual so that the community must raise it directly. People who have more interests or who work may not have to raise clothes directly so they have to leave their more important work. When traveling or there are other jobs the community is still confused how to pick up clothesline with changing weather. From these problems, a prototype model of automatic clothesline was built using Android-based Arduino, this is to simplify and shorten the time in lifting clothesline or drying clothes when our weather changes. Having designed an automatic clothesline using Android-based Arduino. In this study, the Arduino UNO microcontroller functions as a data processing center obtained from the LDR sensor to detect light, uses a water sensor to detect rainwater and uses a DC motor to move the clothesline out / in, and uses the Bluetooth HC-05 module to move the clothesline with Android. The test results show that this tool works well, when the device is turned on the sensor will check the weather outside whether the weather is sunny or rainy. When the weather is sunny or hot outside, the clothesline will automatically come out and if the weather outside is raining, the clothesline will automatically go inside. When the sensor does not function or has trouble the automatic clothesline can be controlled via a smartphone that is connected to the Bluetooth HC-05 module.

The grouping of Mazaya products at PT. Bougenville Anugrah can still do manuals in calculating purchases, sales and product inventories. Requires time and data. For this reason, a research is needed to optimize the inventory of Mazaya goods by computerization. The method used in this research is K-Means Clustering on sales data of Mazaya products. The data processed is the purchase, sales and remaining inventory of Mazaya products in March to July 2019 totaling 40 pieces. Data is grouped into 3 clusters, namely cluster 0 for non-selling criteria, cluster 1 for best-selling criteria and cluster 2 for very best-selling criteria. The test results obtained are cluster 0 with 13 data, cluster 1 with 25 data and cluster 2 with 2 data. So to optimize inventory is to multiply goods in cluster 2, so as to save costs for management of Mazayaproducts that are not available. K-Means clustering method can be used for data processing using data mining in grouping data according to criteria.

This research is motivated by the low writing ability of students, especially in writing poster sentences. In fact, at present, there are still many students at MTs Daarul Uluum PUI Majalengka who have not been able to write poster sentences correctly. In addition to the formulation of the problem, this study also has a purpose. The objectives of this study are as follows. 1) Obtain data about the ability of class VIII students of MTs Daarul Uluum PUI Majalengka in writing poster sentences before learning using the inquiry method. 2) Obtain data about the ability of class VIII students of MTs Daarul Uluum PUI Majalengka in writing poster sentences after learning using the inquiry method. 3) Obtaining data about the effectiveness of using the inquiry method in learning to write poster sentences for class VIII students of MTs Daarul Uluum PUI Majalengka. The method used in this research is a descriptive method, while the techniques used are data collection techniques and data processing and analysis techniques. The population of the study was 5-grade students of MTs Daarul Uluum PUI Majalengka with a total population of 200 students. The sample in this study was 1 class, namely class VIII B with 35 students. The results of data processing and analysis showed the answer to the problem formulation, namely the results of the pretest students' ability in learning to write poster sentences was still low, only reaching 67.29%, but post-test results increased to 84.57%. With the level of effectiveness of using the inquiry method in learning to write poster sentences, it has a correlation of 0.464%, including the moderate categoryPenelitian ini dilatarbelakangi oleh masih rendahnya kemampuan menulis pada siswa, khususnya dalam penulisan kalimat poster. Kenyataannya pada saat ini masih banyak siswa MTs Daarul Uluum PUI Majalengka yang belum mampu menulis kalimat poster secara benar.Tujuan dalam penelitian ini adalah sebagai berikut. 1) Mendapatkan data mengenai kemampuan siswa kelas VIII MTs Daarul Uluum PUI Majalengka dalam menulis kalimat poster sebelum pembelajaran dengan menggunakan metode inkuiri. 2) Mendapatkan data mengenai kemampuan siswa kelas VIII MTs Daarul Uluum PUI Majalengka dalam menulis kalimat poster setelah pembelajaran dengan menggunakan metode inkuiri. 3) Mendapatkan data mengenai efektivitas penggunaan metode inkuiri dalam pembelajaran menulis kalimat poster siswa kelas VIII MTs Daarul Uluum PUI Majalengka Metode yang digunakan dalam penelitian ini adalah metode deskriptif sedangkan teknik yang digunakan yaitu teknik pengumpulan data serta teknik pengolahan dan analisis data. Populasi penelitian adalah siswa kelas VIII MTs Daarul Uluum PUI Majalengka sebanyak 5 kelas dengan jumlah populasi 200 siswa. Sampel dalam penelitian ini adalah 1 kelas yaitu kelas VIII B dengan jumlah siswa 35 orang. Hasil dari pengolahan dan analisis data menunjukkan jawaban terhadap rumusan masalah yaitu hasil pretes kemampuan siswa dalam pembelajaran menulis kalimat poster masih rendah hanya mencapai 67,29%, tetapi hasil postes terdapat peningkatan menjadi 84,57%. Dengan tingkat efektivitas penggunaan metode inkuiri dalam pembelajaran menulis kalimat poster memiliki korelasi 0,464% termasuk kategori sedang.

Intelligent vehicle is an attractive solution to the traffic problems caused by automobiles. An experimental autonomous driving system based on a slot car set is designed and realized in the paper. With the application of a wireless camera equipped on the slot car, the track information is acquired and sent to the controlling computer. A backpropogation (BP) neural network controller is built to imitate the way of player’s thinking. After being trained, the neural network controller can give the proper voltage instructions to the direct current (DC) motor of the slot car according to different track conditions. Test results prove that the development of the autonomous driving system is successful.

The definition and research background of friction is introduced. The reason of generation of friction is analyzed, the importance of the coefficient of friction test in sheet metal forming field is indicated. The testing principle of coefficient of friction on metallic sheet is presented. The basic data processing method of the test is described. Two important data processing techniques which will obviously effects the test results, including effective friction zone and normal pressure have been carefully studied. The comparison result shows these techniques can effectively enhance the testing stability and precision.

The design of the land certificate filing system was built to facilitate the work process in managing land certificate records, especially in the field of archives at the Aceh Besar National Land Agency, which is intended to streamline computerized data processing to support technical implementation in carrying out more accurate land certificate data processing, effective and efficient. A land certificate is a tool or means to convey statements or information in writing from one party to another party. Such information can be in the form of notifications, statements, requests, reports, objections, thoughts, questions, and so on. The design of the system used by the Rapid Application Development (RAD) method, a software development process model classified as incremental (multilevel) techniques. Applications used for making applications are Microsoft Visual Basic .NET as interface design and Microsoft Office Access as a DBMS. The test results of this application are the systems that are built already meet the needs, the input data process has met the needs and the resulting report has met the needs.Keywords:Land Certificate Filing System, Information System, Visual Basic .NET
