Children's Recidivist who Conducted Criminal Act: Legal Psychology Perspective

Children's social environment influences their psychological return to crimes, and it is a treatment or reward from friends which they consider right since they are encouraged to repeat their actions. The research is an empirical legal research. The results shows that The role of psychologists in Special Child Development Institutions is not optimal, due to limited resources. Furthermore, parents or families should actively supervise and limit the association of children as this will prevent them from returning to the social environment. This is because the environment encourages them to commit criminal acts. Also, the government should make provision for their development through the Ministry of Rights and human rights psychologists of any special institute for children's development

Isolasim karakterisasi Enzim Bromelin dari mkulit, buah,Bonggol serta Amobilisasi Enzim Bromelin dari Bonggol Nanas(Ananas comosus L).

Bromelin merupakan enzim proteolitik yang terdapat pada tanaman nanas (Ananas comosus L). Telah dilakukan isolasi dan karakterisasi enzim bromelin dari kulit, bonggol, buah serta amobilisasi bromelin dari bonggol nanas. Dalam penelitian ini bromelin diisolasi dengan metode ekstraksi, fraksinasi dengan ammonium suifat dengan kejenuhan F1 (0-10 %); F2 (10-30 %); F3 (30-50 %); F4 (50-70 %) dan dialisis dalam buffer fosfat. Fraksi-fraksi yang didapat diuji dengan substrat kasein menggunakan spektrofotometer UV-VIS pada maksimum tirosin dan hasilnya diektrapolasikan terhadap kurva standar tirosin untuk mendapatkan nilai aktivitas enzim bromelin. Selain itu ditentukan aktivitas spesifik, yaitu unit aktivitas tiap milligram protein. Kadar protein ditentukan dengan metode lowry. Karakterisasi dilakukan untuk mengetahui karakter bromelin, diantaranya suhu, pH dan waktu inkubasi optimum. Hasil penelitian menunjukkan bahwa enzim bromelin kulit nanas mempunyai waktu inkubasi optimum 5 menit, suhu optimum 43 °C, pH optimum 8,0 dan tingkat kemurnian yang tertinggi pada F3 (30-50 %) dengan aktivitas spesifik 1,629 U.mg-1; enzim bromelin buah nanas mempunyai waktu inkubasi optimum 5 menit, suhu optimum 35 °C, pH optimum 6,5 dan tingkat kemumian yang tertinggi pada F3 (30-50 %) dengan aktivitas spesifik 5,452 U.mg-1; enzim bromelin bonggol nanas mempunyai waktu inkubasi optimum 5 menit, suhu optimum 35 C, pH optimum 6,0 dan tingkat kemurnian yang tertinggi pada F4 (50-70 %) dengan aktivitas spesifik 7,215 U.mg-1. Setelah amobilisasi enzim bromelin bonggol nanas amobil memiliki waktu inkubasi optimum 5 menit, suhu opimum 33 °C, pH optimum 6,5 dengan aktivitas spesifik 7,215 U.mg-I. Stabilitas enzim bromelin bonggol nanas amobil dapat dipertahankan hingga dua kali pemakaian. Bromelain is proteolytic enzyme contained in pineapple (Ananas cornosus L). Isolation and characterization of the bromelain enzyme from peel, stem, fruits as well as bromelain immobilization from the pineapple stem had been done. In the research bromelain was isolated from pineapple by extraction method, fractionation by ammonium sulphate with saturation level of Fi (0-10%); F2 (10-30%); F3 (30-50%); F4 (50-70%) and dialysis in phosphate buffer. The obtained fraction analyzed using casein substrate by UV-VIS spectrophotometer in tyrosin maximum wave length and its result extrapolized to tyrosin standard curve to obtain bromelain enzime activity value. Beside, it was determined the specific activity, activity unit per milligram of protein. Protein degree was determined by lowry method. Characterization have been done to know the character of bromelain like optimum temperature, pH and incubation time. The research result showed that pineapple peel bromelain enzyme have optimum incubation time of 5 minutes, optimum temperature at 43 °C, optimum pH at 8, highest level of purity at F3 (30-50%) with spesific activity of 1.629 U/mg; pineapple fruit bromelain enzyme have optimum incubation time of 5 minutes, optimum temperature at 35 °C, optimum pH at 6.5, highest level of purity at F3 (30-50%) with spesific activity of 5,452 U/mg; pineapple stem bromelain enzyme have optimum incubation time of 5 minutes, optimum temperature at 35 °C, optimum pH at 6, highest level of purity at F4 (50-70%) with spesific activity of 7.215 Wing. After immobilization enzyme have optimum incubation time of 5 minutes, optimum temperature at 33 °C, optimum pH at 6.5 with spesific activity of 7.215 U/mg. Immobilization enzyme stability maintained t

Engaging Multimedia into Speaking Class Practices: Toward students’ Achievement and Motivation

The present study reports several impacts of implementing multimedia toward teaching and learning process in speaking class at second grade students of Galuh University, Ciamis. Further, the study came from insights on students’ boredom during speaking class which affected their achievement and motivation.  Mixed method research design (Creswell, 2013) then employed to answer several proposed hypotheses. For proving the result of its application, observation, questionnaire, pre and post-test were administered to collect the data while both quantitative and qualitative approaches were applied to analyze the collected data from classroom practices. The research findings indicates that  multimedia in speaking class got positive responds from students in term of motivation and accomplishment. The great look portrayed from the class that students were enthusiastic, got involved and interested in multimedia provided by teacher during learning process. Moreover, pre and post-tests that are performace-based tests were greatly used to test the effectiveness of multimedia effects during the class. In this side, the researcher employed experiment of two equivalent groups: control and experimental group. It then reported that t-test related is 2.04  out of 1.70 for  t- distribution which points out that there is significant difference between the results of both tests. It means that the result of this research agreed that multimedia has good effects for teaching speaking in the scope of students’ interests, feedback and their cognitive aspects. In line with above statements, the further studies is also necessary  dealing with other multimedia for obtaining more positive effects toward learning process and those result enables to increase quality of education.
