Abstract

Questioning plays an important role in teaching learning process. The effect of prompting question and non-prompting question in biology teaching learning process on increasing student’s understanding and student’s retention was evaluated in this study.  The method used in the study was experimental involving students in control group who used student experiment and non-experiment worksheet without prompting question and students in experimental group who used student experiment and non-experiment worksheet with prompting question. The study was carried out in 4 concepts, i.e. the environment sustainability, water pollution, environment study, as well as sight organ in Invertebrate. To evaluate the different effect of student worksheet with prompting question and student worksheet without prompting question on increasing student’s understanding and retention posttest 1 and post-test 2 was given to the two groups in time interval of 2,3 and 4 weeks. From the result of the two tests the retention was measured. The study revealed that in the concept of Environment sustainability, environmental study and water pollution the use of student worksheet with prompting question as well as without prompting question was effectively increased student’s understanding to the concept, and the increasing of student’s understanding to the concept between control and experiment group was equally the same. Meanwhile in the concept of the organ sight in invertebrate the use of experiment student worksheet with prompting question more effectively increased student’s understanding to the concept than the use of experiment student worksheet without prompting question. Student in the experiment group performed better retention on the concept than student in control group.

Abstract

Abstrak? Dalam jaringan berbagi atau sharing adalah suatu hal yang biasa, akan tetapi jika sebalik nya maka ada suatu hal yang harus di konfigurasi ulang, seperti perubahan firewall, perubahan topologi logik dari LAN menjadi virtual local area network. Berubahnya topologi logik menjadikan perubahan pada topologi fisik dan perangkat jaringan pun seperti switch harus mengikuti dari switch unmanage ke switch manageable. Begitupula berubah interface pada routernya. Tujuan penelitian ini adalah untuk meningkatkan keamanan jaringan di PT. Navicom Indonesia menggunakan jaringan VLAN karena terdapat permasalahan dimana setiap divisi dapat saling mengakses data pada komputer yang ada, dan data tidak terpisah dari jaringan. Perancangan jaringan VLAN pada PT. Navicom Indonesia. Dalam perancangan jaringan VLAN ini menggunakan aplikasi Cisco Packet Tracer untuk simulasinya. Kemanan data pada setiap pc akan lebih aman apabila menggunakan jaringan VLAN, karena pada jaringan tersebut kita dapat membuat konfigurasi jaringan mana saja yang saling terhubung. Untuk membuat jaringan VLAN saling berkomunikasi maka diperlukan konfigurasi pada Switch untuk membuat Database VLAN, agar setiap anggota VLAN dapat saling berkomunikasi satu sama lain.

Abstract

Based on literature studies, theoretical based for discontinue prosecution in Indonesia is hard to found. However, in develop countries such as US, England or Australia, theoretical based for discontinue prosecution can be identified as first, “realistic prospect of conviction” and second “prosecution on the public interest” theories. These two theories actually can be found in reasoning for SP3, SKPP and article 32 section c Prosecution Act. The primary difference is, in Indonesia, the discontinuity of public prosecution (SP3 and SKPP) is not discretional. In matters when the decision for discontinue the case appears, it put the Public Prosecutor and the Police Officer on dilemmatic position. For example, on the case No.04/Pi.Pralan/2008/PT.SBY and No. 01/Pdt.Praper/2005/PN.Sby, the Police Officers which handle the case still “freeze” the case because they think there is no reasonable prospect of conviction. The same thing happens on the case No.14/Pid.Prap/2010/PN.JktSel.and No: 149/PID/PRAP/2006/PT.DKI, the Public Prosecutor think there is no reasonable prospect of conviction and they think the prosecution is not on the public interest. On these matters, we suggest that there should be comprehensive studies if we putthe discontinuity of prosecution as discretional of power. Furthermore, “reasonable prospect of conviction” or “prosecution on the public interest” should become guidance or theoretical based for discontinue prosecution in Indonesia.
