Abstract

Transportasi adalah sebuah proses pengangkutan atau pemindahan manusia, hewan atau barang dari suatu tempat ke tempat yang lain. Sedangkan bus adalah salah satu jenis alat transportasi darat yang memiliki fungsi untuk membawa penumpang dari suatu tempat ke tempat yang lain dan mampu menampung kurang lebih 65 penumpang. Bus juga merupakan salah satu transportasi umum yang sering digunakan oleh masyarakat Ibu Kota Jakarta, dikarenakan biaya untuk menaiki bus bisa dibilang murah dari pada alat transportasi lainnya. Jakarta memiliki penduduk sekitar 10.557.810 jiwa dengan tingkat kemacetan sebesar 53%. Tujuan penelitian ini memiliki tujuan untuk mengetahui pengaruh dari bnayaknya jumlah bus yang beroprasi terhadap banyaknya jumlah penumpang guna untuk meminimalisir kemacetan atau antrian di setiap zona pemberhentian atau zona pengangkutan dengan menggunakan metode Polynomial Regression. Dari hasil penelitian ini didapatkan hasil korelasi sebesar 0,86 yang memiliki arti bahwa antara jumlah banyaknya bus memiliki korelasi yang tingggi terhadap jumlah banyaknya penumpang.

Abstract

In today's digital technology, almost all activities can be documented in the form of digital images. The problem that arises is that images that are confidential can be stolen and accessed by people who are not entitled. To overcome this security problem, image files can be encrypted using cryptographic algorithms. One cryptographic algorithm that can be used is the Data Encryption Standard (DES) algorithm. This algorithm is a block cipher with a size of 64 bits or 8 bytes. Therefore, DES is used to encrypt image files per 8 bytes. Each encryption process will pass 16 cycles and produce cipher bytes. The result of encryption is an image file with an unrecognized format and cannot be opened because the contents of the byte file have been randomized. To return the scrambled file back to the original image file, perform the decryption process using the same key as the encryption key. The application can be used to encrypt and decrypt images using the DES algorithm. The application can also display the steps of the encryption and decryption process towards the contents of the byte in the file.

Abstract

The development of increasingly sophisticated information and communication technology is inseparable from the growing importance of long distance communication. Current information exchange is not only in the form of text, but can also be in the form of images. All that can be done using an internet connection. With this internet connection, you can connect with many people. Cryptography aims to prevent images from being seen by unauthorized persons so that information stored on a computer is safe or sent through an internet connection. And can protect the confidentiality of the image from various threats that arise. SHA-256 is one of the hashing functions that is safe enough to be used to transform a byte of data into a hash string. The system built has been able to implement the SHA 256 algorithm which can change the original image file in the form of unknown files and encrypted images that cannot be known, unless read using an application that has been built. the image when encrypted and reused when decrypted with as many as 45 characters and may be in the form of numbers or letters. The SHA 256 process when encrypted is only one cycle, can be played with decryption.

Abstract

PT Perkebunan Nusantara IV Jambi Bah Plantation Business Unit is one of the large oil palm plantations that produce crude palm oil.The requirements for the quality of palm oil used as raw material for the food and non-food industries are different. Therefore authenticity, purity, freshness and other aspects must be paid more attention. The selection of crude palm oil levels carried out in the processing section is still manually. This requires quite a long time in the process and does not rule out the possibility of errors in his judgment. Based on the above assessment, there is a problem often found in determining high-quality and high-quality oil, which is to determine the appropriate and appropriate assessment in grading the content or aspects contained in crude oil according to standards and quality. Based on these problems, we need a system that is able to help solve problems in determining the quality of crude oil levels and quality. Thus it can be proposed operational development in determining the levels contained in crude oil using the MOORA method in deciding quality oil levels based on existing criteria. From the test results tested with 16 alternatives, the highest results can be obtained, namely alternative A3 with an alternative name 8774 LU with a value of 0.2738 so that it can be concluded that alternative A3 has high quality and quality oil content.

Abstract

The need for electrical energy in everyday life is so important, improper and uncontrolled use can result in waste. Efforts to create energy-efficient homes need to start from simple things such as the use of lights, often forgetting to turn off the light switch when going out of the house or problems, especially in setting the brightness of the house lights, fuzzy logic provides an alternative solution. Fuzzy logic is a smart method that is appropriate for mapping a parameter input space into an output space for the brightness adjustment action of a lamp to light dimly, medium and bright. Efforts that can be made to deal with the problems above certainly require an intelligent control system with smart methods such as fuzzy logic and can be controlled remotely in order to overcome the existing problems. One concept that is popular right now is the Internet of Things (IoT), the development of IoT is a concept that aims to expand the benefits of internet connectivity that is connected continuously. IoT has capabilities such as data sharing, remote control, and so on. In building a control system by applying the IoT concept, a platform that supports that concept is also needed, NodeMCU a microcontroller which is equipped with a wifi module for microcontroller communication to the internet, so that the microcontroller can be used to apply the IoT concept in controlling home lights remotely, such as turning on the remote and turn off and adjust the brightness of the home lights with the fuzzy logic method intelligence.

Abstract

Food needs are very important, but how about if there is a food is difficult to find in the local market. Problems arise because of difficulties in finding stalls or other markets that have food or agricultural products to be sought. By looking back at the development of various types of marketplaces in this era, it would be very helpful to create a locally-based marketplace, which only displays food products in the surrounding area, so that it can provide opportunities for local farmers to market their products. "AGRITION" WEB-BASED AGRICULTURE SOLUTION is a web application in the form of a marketplace that is designed to facilitate consumers in finding products or locations of food or farm stalls in Pontianak according to the needs of Sellers and Buyers. By using the PHP programming language and MySQL database. The researcher designed the design using ERD (Entity Relationship Diagram) and LRS (Logical Record Structure) along with components such as entities, attributes and their relationships.

Abstract

To increase bean production, bean seedlings have an important role in its cultivation. The use of superior seeds is one of the factors that influence the productivity of chickpea farmers. The presence of bean seeds at any time causes farmers to plant on time. Problems that often arise in the process of selecting bean seed systems include farmers needing a long time in determining the type of bean seeds because they have to choose manually with the criteria needed to determine the type of bean seeds desired and farmers also have not used a scientific way to choose the type bean seeds so that sometimes the results obtained are not as expected. Then it is necessary to develop a computer application as an alternative decision making that is used quickly and accurately. One of them is the Decision Support application that helps users to determine the decision quickly, precisely and accurately. This system is designed with the Multi Factor Bobot Evaluasi Process method which aims to determine decisions subjectively and intuitively by considering several factors that affect alternatives. Therefore the Decision Support application with the Multi Factor Bobot Evaluasi Process method and SMART can be to alternative for the decision maker to determine the bean seeds.
