The rapid development in the telecommunications and digital world today makes android-based mobile devices basic needs for many people. The devices have even provided various kinds of learning media for the community. Further, even though the devices are easily to apply as learning media, they have not been a priority for Muslims in improving their knowledge, such as Sirah Shahabiyah (the journey of a female companion of the Prophet Muhammad). Due to the community’s little interests in learning Sirah Shahabiyah, it is necessary to create a learning application that allows the user and the community to easily learn it. The methods used to collect the data of this research are field study, literature review and previous literature review. The system is developed using a prototype system development method consisting of the stages of planning, analysis, design and implementation and is designed using Unified Modeling Language (UML). The result of this research is a learning application in the form of android-based Sirah Shahabiyah, by which the user and the community can easily learn Sirah Sahabiyah, facilitating pleasant and effective learning activities.

Seiring dengan maraknya usaha di bidang sayuran hidroponik, UD. Media Farms menyadari akan munculnya persaingan bisnis yang ketat, sehingga diperlukan strategi untuk menarik konsumen, kurangnya sumber informasi baru menjadi salah satu kendala kemajuan bisnis. Tujuan dari penelitian ini adalah untuk mengetahui informasi mengenai sayuran apa saja yang sering dibeli konsumen secara bersamaan dalam satu kali transaksi guna mengoptimalkan hasil panen sayuran hidroponik dan menentukan strategi bisnis penjualan sayuran hidroponik. Metode data mining yang digunakan dalam penelitian ini adalah metode association rule dengan algoritma apriori. Dari proses pengolahan data menggunakan algoritma aprori dan pengujian dengan alat rapid miner, dengan parameter support minimal 20% dan confidence minimal 60% maka aturan asosiasi yang terbentuk adalah 7 aturan. Dari 7 rule yang terbentuk, ditemukan 3 rule dengan nilai confidence tertinggi yaitu (selada → kangkung) dengan nilai support 50% dan confidence 79%, (selada, bayam merah → kangkung) dengan nilai support 25% dan kepercayaan diri 78%, (selada, pakcoy → kangkung) dengan nilai support 22% dan confidence 76%. Ketiga rule tersebut memiliki nilai lift ratio > 1 yang artinya rule tersebut valid dan dapat digunakan dengan baik.

To overcome this, especially in the selection of the Village Head, in this study a web-based electronic voting system (e-Voting) was made using a fingerprint sensor that aims to collect voters' data so that voters get their voting rights and their voting rights cannot be used by other citizens. The method used in developing this application is the waterfall method which includes the stages of needs analysis, system design, coding and testing, testing and maintenance. The result of this research is an up to date e-Voting system for counting votes, so as to minimize fraud occurring at the time of village head election. So the conclusion obtained from this study that web-based e-Voting using a fingerprint sensor can produce a quick election winner decision because it does not require tiered and accurate vote counting because citizens who choose according to the data registered.
