Efektivitas Ekstrak Daging Buah Nanas (Ananas comosus L.) Dalam Penurunan Indeks Browning Dari Umbi Kentang (Solanum Tuberosum L.)

The purpose of this study was to determine whether the pineapple fruit extract can inhibit theprocess of browning on the potato tubers. This study used Completely Randomized Design(RAL) with 5 levels of pineapple fruit concentration of 0% v/v, 25% v/v. 50% v/v, 75% v/v,and 100% v/v and consist of 5 replications. Qualitative Parameters in this study was the colosurface of potato tubers while quantitative parameters were browning index, total soluble carbohydrate content, and dehydrogenase enzyme activity homogeneity of variance, analysisof variance, and Tukey test were conducted at 5% significant level. Correlations betweendependent and independent variables were determined by linear regression. The resultshowed that the color surface of potato tuber treated with the concentration of pineappleextract 100% v/v was less brown than control and other concentrations. Index browning ofpotato tuber treated with concentration 75% v/v and 100% v/v was significantly decreased. Concentration of pineapple extract was negative linearly correlated to browning index ofpotato tubers. The concentration of pineapple extract 100% v/v increased significantly totalsoluble carbohydrate of potato tubers. The concentration of pineapple extract was positivelinearly correlated to total soluble carbohydrate. The activity of dehydrogenase enzyme ofpotato tuber treated with concentration 100% v/v was significantly increased. Theconcentration of pineapple extract was quadratic correlated to the activity of dehydrogenaseenzyme

Penerapan Model Pembelajaran Kooperatif Tipe Numbered Heads Together (Nht) untuk Meningkatkan Hasil Belajar IPS Siswa Kelas V Sdn 003 Teluknilap Kecamatan Kubu

The results of the first cycle of observationshowed good activity has started 16 teachers (66.66%) in accordance with theplan, to observation of teacher activity at the second meeting considered either 18(75%). For the second cycle of activity observed with the category of teachers hasincreased very well 22 (91.66%) and in accordance with the plan, to aobservasiteacher activity at the second meeting of the second cycle also increases the verygood category 23 (95.83%). While the observation of student activity is good alsoat the first meeting of 16 (66.66%) and at the second meeting of 18 (75%) In thesecond cycle of observation of student activity increases with category very well22 (91.66) and also activity increases with category students very well at the lastmeeting 23 (95.83%). Based on the analysis of data from the discussion, theaverage value of the basic scores of students before the implementation ofcooperative learning model Number Heads Together (NHT) is 63.66. Thenincreased to 71.88 in the first cycle and increased again in the second cycle is83.82 thus it can be concluded that with the implementation of cooperativelearning model Number Heads Together (NHT) can improve learning outcomesIPS Elementary School fifth grade students 003 Gulf Nilap Kubu district
