Abstract

Zygomycota and Ascomycota Classesare classified as the Fungi Kingdom groups It is needed to hold a practicum activity in the fungi grouping learning. Nevertheless, the tools and materials at school to observe the fungi are inadequate. Therefore, it is necessary to hold a fungi practicum which accompanied with a students worksheet that is able to develop the students’ science process skills so that the teachers and the students are able to achieve the learning objectives of the Fungi material. This study aims to analyze the students science process skills after the application of guided-inquiry learning model in the fungi practicum activity. The study used pre-experimental design method with one-shot case study design as the research method. Furthermore, the students’ understanding level is obtained based on the results of the students skill score, such as the ability to observe and to conduct an experiment which able to reach the defined completeness criteria. The result shows that the observation skills score of class X.MIA.1 and class X.MIA.3 were 85% and 91% and the experimental skills score of class X.MIA 1 and class X.MIA.3 were 85.7% and 88.5%. The understanding of fungi material is classified successful in Fungi practicum learning activity due to the classical completeness that reaches above 85%.

Abstract

This study aims to determine differences in the viability of Lactic Acid Bacteria (LAB) isolates on MRS medium supplemented with various concentrations molasses. Concentration variation molasis used as controls were 0%, 1%, 2% and 3%. Variation of time incubation on each of the media that is 0 hours, 24 hours, 48 hours and 72 hours. The viability of each isolate was viewed with the population of Log (cells/ml) which grow on the medium and the number of generations and time of generations. The results showed that the concentration molasses added to MRS affect the viability of LAB. Concentration of 1% makes LAB better viability than controls. Total population continues to increase at the end of the incubation with a yield of 1.17 generations in time 20.46 hours/generation. In contrast to controls, reduced population size at the end of the incubation so as not to produce a generation. LAB viability in addition molasses 2% and 3% live on 48 hours of incubation. This is indicated by the number of population increased at 48 hours of incubation, and then decreased at the end of incubation. The addition of concentration variation in the types of bacteria showed different viability. At B1 adding molasses 2% and 3% live on 48 hours of incubation and control can only live on a 24 hours incubation, whereas the B3, the control can remain alive at 48 hours of incubation. In contrast to the controls on B4 can survive on 48 hours of incubation, whereas the addition of 3% molasses can only live on a 24 hours incubation. Key words : Lactic Acid Bacteria/LAB, Molasses,  Viability

Abstract

Pemenuhan asupan gizi bagi ibu hamil dipengaruhi oleh banyak factor, antara lain pengetahuan. Ibu hamil yang mempunyai pengetahuan gizi yang baik akan memenuhi kebutuhan gizinya sehingga berdampak pada peningkatan status gizi. Peningkatan status gizi pada ibu hamil dapat dilakukan dengan cara banyak mengkonsumsi makanan dengan gizi seimbang sehingga sedikit kemungkinan untuk menderita KEK. Tujuan Penelitian Untuk mengetahui hubungan antara pengetahuan tentang pola makan yang baik dengan terjadinya kejadian kekurangan energi kronik (KEK) pada ibu hamil. Penelitian ini menjelaskan hubungan antara variabel bebas dan terikat. Metode yang digunakan yaitu dengan menggunakan kuesioner serta pendekatan cross sectional. Populasi penelitian ini adalah seluruh ibu hamil bulan juni 2016, pengambilan sampel menggunakan rumus simpel size dan didapat 49 sampel dengan cara penetapan sampel menggunakan random sampling. Peneliti menggunakan analisa bivariate. Dari 49 responden ibu hamil, ibu hamil yang memiliki pengetahuan yang baik mengenai pengetahuan tentang pola makan lebih banyak yaitu sebanyak 55,2% dan pengetahuan yang kurang baik sebanyak 44,8%. Kejadian KEK juga lebih sedikit yaitu 20,4% dan yang tidak KEK sebanyak 79,6%.
