According to Norton, Sanchez, Clarke-Harris, & Traoré (2003), there is a quick-rising in the production and export of horticultural products in many developing countries. Data have shown that from 1970 to 2002, fruit and vegetable production in developing countries increased almost fourfold from 256 to 960 million metric tons, while exports more than triplicated from 1.9 to 6.5 million metric tons. The stimulus for a request for such highvalue commodities include income increase, transportation costs decrease, and, in some cases, improved market access. Production for export is often fostered as a means of producing foreign exchange, boosting incomes to producers, and giving employment to the poor in a rural area. As for the importing countries, they get an advantage from bigger product stocks that generally have been limited and costly in the off-season.In Indonesia, there were five seasonal vegetable commodities with the largest production in sequence, namely shallots (1.4 million tons), cabbage (1.44 million tons), large chili (1.21 million tons), potatoes (1.16 million tons), and ARTICLE INFO

The study of aspects of human behavior in a particular group which includes aspects caused by the influence of organizations on humans as well as human influences on organizations including organizational behavior. There are two factors that influence individual behavior towards Islamic educational institutions, namely internal and external factors. Internal factors include heredity (heredity or innate). External factors include the environment, maturity or experience and education. While the individual behavior analysis variables include psychological, physiological and environmental variables. Psychological variables include perceptions, personality attitudes, learning and motivation. Physiological variables include physical abilities and mental abilities. And environmental variables include family, culture and social class. As an initial understanding to be able to understand individual behavior well, it is necessary to understand the characteristics inherent in individuals which include biographical characteristics, personality, perceptions and attitudes. The verses of the Qur'an relating to individual behavior form the basis that Islamic educational institutions have hinted that humans have positive and negative potentials in behavior, and in essence the positive potential of humans is stronger than their negative potential.

Abstrak— RSA (Rivest Shamir Adleman) merupakan algoritma asimetris yang paling banyak digunakan dalam kriptografi. Dalam beberapa penelitian menyebutkan bahwa proses RSA memakan waktu yang cukup lama. Untuk mempercepat waktu proses dari RSA dilakukan penambahan suatu algoritma CRT (Chinese Remainder Theorem) untuk mengurangi perhitungan aritmatika modular dengan modulus besar dalam RSA yang disebut RSA-CRT. Dalam penelitian ini penulis akan membandingkan dua algoritma asimetris yaitu RSA (Rivest Shamir Adleman) dengan modifkasi RSA yaitu RSA-CRT (Rivest Shamir Adleman-Chinese Remainder Theorem) pada data teks berukuran besar dari segi efisiensi waktu. Algoritma RSA dan RSA-CRT digunakan untuk mengenkripsi dan mendekripsi suatu data teks berukuran 5 mb, 10 mb, 15 mb dan 20 mb untuk dibandingkan efisiensi waktu atau segi kecepatan prosesnya. Hasil pengujian waktu dari penilitian ini menunjukkan bahwa nilai waktu dari proses enkripsi antara algoritma RSA dan RSA-CRT tergolong sama sebab kunci publik yang digunakan rumusnya memang sama. Sedangkan dari proses dekripsi menunjukkan bahwa algoritma RSA-CRT lebih cepat dari pada algoritma RSA biasa. Dari pengujian kecocokan kunci menunjukkan bahwa kunci yang bangkitkan dan digunakan untuk proses enkripsi dekripsi harus berpasangan antara kunci publik dan kunci privatnya. Hasil pengujian ukuran file dari proses enkripsi mengalami kenaikan dengan rata-rata 42.757 kb, sedangkan dari proses dekripsi berkurang dengan rata-rata 0,007 kb dikarenakan terdapat karakter yang tidak dikenali sistem yaitu simbol bullets list yang mengakibatkan file tidak dapat kembali 100% seperti semula. Sehingga dapat disimpulkan bahwa dalam proses dekripsi suatu data teks berukuran besar algoritma RSA- CRT memiliki efisiensi waktu 50% dibandingkan dengan algoritma RSA biasa.Kata Kunci— Algoritma Elgamal, Kriptografi, Enkripsi, Dekripsi, Gambar Warna.

In an effort to increase additional education programs to gain knowledge and skills in carrying out duties and functions, it can improve the performance of employees in the hospital. The phenomenon of the need for medical and non-medical personnel as personnel providing services in the hospital if you find emergency victims, both patients and hospital visitors, must understand the SOP for handling emergency patients. In addition, every medical service provider must have BLS capability. Patients are unconscious and do not see who is helping and where is the place, even patients are often not aware that the helper is not medical (non-medical), so the hospital requires medical and non-medical personnel to be able to do BLS. This type of research is descriptive quantitative. The purpose of this study is to provide an overview of the characteristics of non-medical employees, whether there is a relationship with knowledge based on the training that has been followed. The research sample is that all non-medical employees who have attended BLS training at RSI Surabaya A.Yani are 33 people. Characteristics of respondents at the Surabaya Islamic Hospital with the age category> 45 years 39.4%, the majority are male 51.5%, the latest education is a bachelor's degree 51.5%, the status of permanent employees is 81.8%, the majority is married marital status 82 %, working period 16-25 years 33.3%. The conclusion of this study is that the knowledge of non-medical employees at the Surabaya Islamic Hospital is declared good because by participating in the training, they can gain knowledge and skills in performing first aid actions for victims.

Penelitian Tindakan Kelas ini dilatarbelakangi adanya    masalah kurang aktifnya peserta didik dalam pembelajaran matematika pada kompetensi persamaan dan fungsi kuadrat  sehingga mengakibatkan   hasil belajar rendah  pada peserta didik kelas XI TKRO2 SMK Negeri 2 Slawi. Tujuan penelitian ini adalah untuk meningkatkan aktivitas dan hasil belajar kompetensi persamaan dan fungsi kuadrat pada   peserta didik kelas XI TKRO 2 di SMK Negeri 2 Slawi   melalui model pembelajara Cooperative Learning tipe STAD. Hasil penelitian menunjukkan model pembelajara Cooperative Learning tipe STAD dapat meningkatkan aktivitas peserta didik, dilihat dari adanya peningkatan banyaknya peserta didik yang mendengarkan penjelasan dari guru, banyaknya peserta didik yang menanyakan hal yang belum dipahami, banyaknya peserta didik yang mau menjawab pertanyaan dari guru, dan banyaknya siswa yang aktif mengerjakan tugas-tugas dari guru. Penguasaan materi juga mengalami peningkatan dilihat dari adanya peningkatan hasil belajar. Sebelum dilakukan tindakan nilai rata-rata hasil hasil belajar 6,91. Setelah diberi tindakan pada siklus 1 nilai rata- rata mengalami peningkatan menjadi 7,48 dan pada siklus 2 meningkat menjadi 7,85. Ketuntasan belajar juga mengalami peningkatan, dari 33 peserta didik sebelum tindakan hanya ada 20 speserta didik (60,61%) yang tuntas belajar, pada siklus 1 menjadi23 peserta didik (69,70 %) yang tuntas dan pada siklus 2 menjadi 26 peserta didik (78,79 %) yang tuntas. Kesimpulan yang  diperoleh dari data tersebut di atas menunjukkan bahwa model pembelajara Cooperative Learning tipe STAD secara signifikan dapat meningkatkan aktivitas dan hasil belajar peserta didik  pada kompetensi persamaan dan fungsi kuadrat.
