E-business security becomes an important issue in the development of technology, to ensure the safety and comfort of transactions in the exchange of information is privacy. This study aims to improve security in e-business systems using a hybrid algorithm that combines two types of keys, namely symmetric and asymmetric keys. Encryption and decryption of messages or information carried by a symmetric key using the simple symmetric key algorithm and asymmetric keys using the Rivest Shamir Adleman (RSA) algorithm. The proposed hybrid algorithm requires a high running time in the decryption process compared to the application of a single algorithm. The level of security is stronger because it implements the process of message encryption techniques with two types of keys simultaneously.

The application of various agricultural technologies such as the using by fertilizers, pesticides, and clearing land will have resulted changes in the ecosystem. Using by insecticides can gived negative impact such as causing resistance, resurgensy and environmental pollution due to residues that can last a long time and are difficult to decompose, because it have compound among other carbon, chlorin, and hidrogen. Piper methysticum (Piperaceae) is one of plant which are used for medicine and social-cultural activitiy by Merauke community, Papua. Meanwhile, Crocidolomia pavonana (Lepidoptera:Crambidae) is one of major pest on the family Brassicaceae plants. The objective of this research was to effectiveness test for simple extract P. methysticum leaves as a botanical insecticide against C. pavonana larvae (Lepidoptera: Crambidae). The insecticide activities were assessed including mortality. Mortality tests using leaf wet method were seven concentrations (5 gr/100 ml, 10 gr/100 ml, 15 gr/100 ml, 20 gr/100 ml, 25 gr/100 ml, 30 gr /100 ml, 35 gr/ 100 ml) plus control. Each treatment was introduced ten C. pavonana instar 2 nd larvaes and replicated five times. The results showed that extract P. methystichum leaves gave 22% mortality at 35 gr/100 ml water.
Usaha penggilingan padi merupakan jenis usaha kategori UMKM industri pengolahan yang menghasilkan produksi beras yang siap dikonsumsi. Usaha ini menjadi pusat pertemuan antara produksi, dan distribusi atau penjualan hasil produksi, sehingga berperan penting dalam sistem agribisnis dalam perberasan di Indonesia. Manajemen transaksi operasional harian pada usaha penggilingan padi masih dilakukan secara tradisional, sehingga mengakibatkan pelayanan yang diberikan kurang optimal, karena membutuhkan waktu yang lama, seperti melakukan pencarian berkas atau nota yang menjadi bukti terjadinya transaksi. Masalah lain yang terjadi yaitu, untuk mengetahui keuntungan jasa penggilingan padi, masih dilakukan dengan melakukan rekapitulasi nota atau bukti transaksi secara manual. Penelitian ini bertujuan untuk mengembangkan sistem E-business untuk manajemen transaksi pada usaha penggilingan padi, sehingga dapat meningkat pelayanan kepada pelanggan, dan menyediakan informasi secara real time terkait keuntungan jasa penggilingan, penjualan, pembelian, dan dan manajemen data transaksi lainnya secara elektronik. Tahapan kegiatan penelitian diantaranya yaitu : analisis kebutuhan pengguna, pengumpulan data, analisis kebutuhan fungsional dan non fungsional sistem, desain, pengembangan, dan pengujian sistem. Hasil implementasi sistem menunjukkan bahwa sistem dapat digunakan untuk manajemen kegiatan transaksi pada usaha penggilingan padi, yang menyajikan informasi transaksi jasa penggilingan, transaksi pemlian beras, penjualan , hasil keuntungan jasa penggilingan bulanan, dan tahunan, sehingga sistem dapat digunakan sebagai media informasi yang akurat mengenai transaksi bisnis yang terjadi bagi pemilik usaha penggilingan padi guna meminimalisasi resiko keamanan dalam melakukan transaksi
The spread of the Covid 19 virus in 2019 and continuing in 2020 has made all members of thecommunity remain vigilant in maintaining public and individual health.
