Fly ash and bottom ash are solid waste from coal combustion in the operating system of Steam Power Plant (PLTU). The research was conducted by combining fly ash and bottom ash with an adhesive consisting of portland cement. Based on the tests performed the maximum mixture obtained with cement samples, fly ash and bottom ash is 1: 2: 2. Paving blocks made from fly ash and bottom ash have compressive strength values resulting in compressive strength values of 50.52 MPa. This value indicates that the sample is in the class of paving blocks A. Paving Block made from fly ash and bottom ash also has a very good average air absorption value, in a combination of suitable cement mixtures, fly ash and bottom ash (1: 2: 2) the average air absorption value is still 5.06%. This value shows that the sample is in class B paving blocks.

Blitar Regency is one of the strange culinary centers, among which are processed various foods from snail base ingredients, ranging from kripik, sate oseng-oseng and so on as well as the existence of Blitar district is one of the rice barns in East Java. With the existence of Blitar district as a snail-based culinary producer and one of the rice barns in East Java, this is not spared from several problems, such as the disposal of snail shells in the river and burning of rice straw in rice fields which both will cause environmental damage. This study aims to examine the use of snail shell ash and rice straw ash as a substitute material for cement in mortar mixtures against mortar compressive strength. The research method used was the experimental method by mixing fine aggregate main ingredients with snail shell ash and rice straw ash then testing the compressive strength. The results of the compressive test with the addition of the percentage of snail shell shell turned out to increase by 54.78%.

Dalam menentukan luas objek persegi, persegi panjang, dan lingkaran diperlukanlah sebuah penggaris untuk mendapatkan nilai luasannya, agar lebih mudah dan praktis dapat dibantu dengan sebuah web camera dengan cara mengcapture gambar sampel objek yang ingin diketahui luasnya. Image Prosessing adalah suatu proses yang digunakan untuk mengolah citra atau gambar untuk mendapatkan citra yang lebih bagus mengunakan perangkat sistem komputer. Untuk mendapatkan perolehan panjang (X,Y) dari gambar dapat diukur setelah melewati beberapa tahapan di image prosessing yaitu dengan konversi citra dari RGB, HSV dan deteksi tepi canny, lalu terdapatlah nilai luasan dari hasil pengukuran objek. Metode Canny sendiri merupakan deteksi tepi paling baik ketika digunakan untuk mendeteksi tepi objek, sehingga hasil deteksi tepi tersebut dapat diambil informasi yang berguna dari citra tersebut. Dengan pengukuran luas secara manual dan secara otomatis terdapat presentase error kurang lebih 5%, hasil luas objek tersebut sudah cukup akurat namun terdapat masalah jika dalam pembuatan objek kurang presisi, peletakan objek yang miring/kurang tegap dan pencahayaan yang kurang mengakibatkan kurangnya tingkat akurasi.In determining the area of a square, rectangle, and circle object a ruler is needed to get the area value, so that it can be easier and more practical to be assisted by a web camera by capturing the image of the object sample that you want to know the area. Image Prosessing is a process used to process images or images to get better images using computer system devices. To get the long gain (X, Y) from the image can be measured after passing through several stages in image processing that is by image conversion from RGB, HSV and canny edge detection, then there is an area value from the object measurement results. The Canny method itself is the best edge detection when used to detect the edge of an object, so that the useful information of the edge detection can be retrieved from the image. With the area measurement manually and automatically there is a percentage error of approximately 5%, the object's width results are quite accurate but there is a problem if the object is less precise in making objects, sloping / less robust object laying and less lighting result in a lack of accuracy.

Berdasarkan hasil percobaan pada setiap sampel dapat menunjukan tingkat kekeruhan yang berbeda dan dapat membedakan tingkat kekeruhan air dengan 3 tingkatan kekeruhan. Jika nilai ADC kurang dari 153 indikator LED berwarna hijau akan menyala, air dinyatakan tidak keruh. Jika nilai ADC lebih dari 154 dan dibawah nilai 158 indikator LED berwarna kuning akan menyala, air dinyatakan sedikit keruh.

By using this system the user must enter the order number obtained after the customer makes an order in the marketplace for verification if they want to make a design order. Admin can manage user access to order designs and manage the design queue properly. White box testing method is done to find out how the system works structurally, besides to find out things that might happen when the system is run. In the white box test on the user login page and the design orderi ng page, the system works well as evidenced from the testing phase as in Cyclomatic Complexity and Matrix produces a value of 2 for the user login page and 1 for the design message page.

Egg quality is determined by the quality of the inside and outside of the egg. To find out the quality of eggs canbe by looking at the outside in the form of skin condition, shape, size, and egg weight. In this study a system isdesigned to function to determine the quality of egg quality based on color and texture features. Broadlyspeaking, the system built consists of 4 main processes. This process begins with pre-processing which aims toimprove image quality and also to change the image size. The next process is segmentation to get the egg object.The next process is feature extraction which aims to get the characteristics of each egg object. The last processis a classification that aims to determine the class of egg images entered by the user, the method used is knearest neighbor. The data used in this study were 147 egg images consisting of 85 eggs of data testing and 62eggs of training data. The highest accuracy obtained from this study is 82.3% with a value of 8

This aim of this researh is to classify an assessment sentence from students, then classified to produce an information. Classification is used to determine the character of each student so that teachers have no difficulty in assessing the social character of the student, based on asesment orientation On Kurikulum 2013.
