ABSTRAKThe main problem in the process sentiment analysis review is how to choose and use the best feature selection to get the maximal result. The accuracy of the use of algorithm in analysis sentiment review also have been an important role in the determination results of the analysis. Analysis of the sentiment is a study computing on an opinion, behavior and emotion of a person to an entity. This research also discussed comparative studies, technique classification and combining method of the feature selection to comparsion result of the people opinion about tourist destination. The classifications technique to analyze sentiment review of the tourist destinations, using support vector machine algorithm (svm) and a model of the features selection will be compared between a particle swarm optimization and genetic algorithm to increase the accuracy classifications of support vector machines algorithm. The measurement of were based on accuracy support vector machines before and after the addition of features. The evaluation uses 10 cross fold validation. While the measurement of accuracy measured by confusion the matrix and a curve roc. The result showed an increase in accuracy support vector machines of 75.33 % to 88.67 %. Keywords: Sentimen Review, Support Vector Machine, Analysis Review, Feature Selection.

PT. Asia Berjaya Mobilindo merupakan salah satu perusahaan di Indonesia yang bergerak di bidang penjualan, perawatan serta penjualan suku cadang mobil bermerk Mazda. Pengolahan data pegawai pada PT. Asia Berjaya Mobilindo masih dilakukan secara konvensional dan menimbulkan beberapa kendala bagi pegawai terutama pada saat pengajuan cuti dan penerimaan gaji. Pengajuan cuti yang ditujukan ke manajer HRD dilakukan dengan menggunakan surat cuti dan harus diserahkan secara langsung, adanya keterlambatan dalam pendistribusian slip gaji dan adanya kesalahan dalam perhitungan gaji yang menyebabkan pegawai menerima gaji tidak sesuai dengan yang seharusnya diterima oleh pegawai. Oleh karena itu, diperlukan sistem informasi pengajuan cuti, slip gaji dan rekap absen karyawan yang sesuai dengan PT. Asia Berjaya Mobilindo dengan menggunakan metode Framework for The Application of System Thinking (FAST) dengan diagram Unified Model Language (UML) sehingga sistem yang dibangun mampu menyelesaikan permasalahan pada pengolahan data pegawai pada PT. Asia Berjaya Mobilindo dan memudahkan pegawai dalam mengajukan cuti, melihat slip gaji dan melihat absen.

One factor of success in a housing construction project is the monitoring of each division that is interrelated and connected with each other. It would be very inefficient if from each party there was no clear and uncontrolled communication. As with the Jakarta Housing Corporation, currently monitoring the project has not been well integrated. Where information that is intertwined with regional offices is still limited to communication information by telephone, as well as data that is used using documents or archives that can sometimes be lost or forgotten in the storage. Of course this will slow down the project development process, because it is constrained by each of the relevant parties, plus the report must be presented or needed at any time by the director. For this reason, a system that can support the monitoring process is needed so that data can be stored properly and the control of the progress of each project is monitored from the center. One of them is the creation of a web-based system application, with this system all can be done in real time.

Indonesia is an agrarian country, which is a sector that plays an important role most of the Indonesian population makes agriculture the main focus, but the function of rice fields into housing or industry has resulted in a decrease in rice production, in addition to pests, diseases, unfavorable weather, Irrigation is not smooth resulting in less than the maximum yield. For this reason, it is necessary to have technology that can implement the process of detecting rice leaf disease in order to provide information to farmers about rice leaf damage. The most modern approach today can be done with machine learning or deep learning by using various algorithms to improve recognition and accuracy in the detection and diagnosis of plant diseases. Based on this, this study aims to propose a method of classifying rice leaf diseases in order to provide information to farmers about rice leaves which are expected to reduce the disease by detecting the disease early so as to increase rice production. In this study, the classification process is carried out using the augmented image, then the Color Histogram feature extraction method is applied, and the classification is carried out using the Random Forest algorithm. In addition, this study also conducted several comparisons, including feature extraction and yahoo to get the results, and the highest results reached 99.65% of the proposed method.

The level of performance can be assessed through the level of attendance of employees of a company, attendance is one of the parameters in evaluating employee performance. Several companies or government agencies will always maximize facilities in supporting their work activities, including the employee attendance system. Unfortunately, not all agencies or companies can implement the system properly. Some of them still use the traditional way of recording attendance. This of course can cause some problems both in terms of users or data management, especially if the number of users who make attendance is very large. In addition to data management problems, other problems such as an authentication system that is less secure and prone to fraud can occur. The purpose of this study is to design and implement an android application to make it easier for users to carry out the presence process that is installed on registered devices with the support of scanning a QR code that is generated randomly for each session with biometric authentication support to ensure only verified users run the application. Based on the statement, the application of application-based presence can speed up users in carrying out the presence process with just a few steps, and increase security and user validation.

Saat pandemi Covid-19 mulai melanda di Indonesia, banyak pembatasan yang diterapkan oleh pemerintah untuk membatasi merebaknya virus tersebut. Masyarakat dan dunia usaha secara otomatis juga mengalami ketidakstabilan dalam perekonomian karena pembatasan tersebut. Oleh karena itu pemerintah juga mulai membuat kebijakan untuk melindungi perekonomian masyarakat dengan menyalurkan bantuan sosial kepada desa atau kelurahan diseluruh Indonesia. Penelitian ini bertujuan untuk memberikan kontribusi yang nyata tentang kelayakan penerima bantuan agar penyaluran bantuan benar-benar tepat sasaran sehingga bisa mengangkat perekonomian masyarakat yang turun drastis karena pandemi ini. Metode dalam penelitian ini menggunakan metode survey lapangan dengan memberikan batasan kriteria pada pendapatan bulanan, jumlah tanggungan, jenis tempat tinggal, dan kendaraan yang dilakukan pada salah satu kelurahan di wilayah Tangerang dengan metode klasifikasi C4.5. Hasil output dari penelitian ini adalah menentukan apakah penerima bantuan yang terdaftar tersebut layak atau tidak layak untuk menerima bantuan yang dapat dijadikan rekomendasi oleh pengambil keputusan, dalam hal ini pihak kelurahan untuk menyeleksi warganya.
