Improving learning quality in 21 st can not be separated from contextual learning and student-centered learning paradigm. The contextual lesson study program conducted in learning-forest prototype to build a learning community. The objectives of this research were to improve learning activities of postgraduate students in Biology Education department and to build a learning community. The implementation of lesson study was conducted in the Biology Learning Innovation subject for postgraduate students while practicing to observe open lesson in the undergraduate students which used learning forest-prototype. The postgraduate students took roles as planner, observer, and reflector in the plan, do (open lesson), and see (reflection) activities. The implementation was done in three cycles in even semester of academic year 2015/2016. Students learned collaboratively and contextually. The postgraduate students' learning activities were observed by six observers from lecturer colleagues. The research results showed that the students were able to implement planning, open lesson, and reflection properly. The average of student's learning activity grade was 91.11% from all of students, with the grade averages for planning, open lesson, and reflection activities were 88.89%, 93.33%, and 91.11% respectively. The implementation of this lesson study in the learning forest-prototype can be done in other relevant subjects to strengthen learning activities.
Coffee is a strategic commodity that generates promising foreign exchange, where Lampung is the main coffee production centre which continues to increase its production, and more than 80% of it is smallholder coffee. Between 40% and 55% of coffee, production is coffee husk waste, which has not been optimally utilized. Previous research showed that pineapple liquid waste indigen bacteria (Pumakkal) were able to increase acidity and decompose waste organic matter, and the final result was a suitable fertilizer for plant cultivation. This research will solve the problem of coffee husk waste used as compost by utilizing a starter from the previously tested pineapple liquid waste bacteria (Pumakkal). The research was conducted with the first stage of making coffee skin compost with a starter formula of KA (3 bacteria), KB (6 bacteria), KC (9 bacteria), KD (12 bacteria) and KE (15 bacteria), the second stage was to test the quality of the coffee husk compost organic fertilizer followed by a pilot plan application using the best formula. The application uses spinach and chilli plants. The result shows that KC is a model the most appropriate coffee skin compost starter formula.
Pesisir Barat Regency in Lampung has abundant marine biological wealth that has not been widely known and utilized by the community, one of them is macro algae. The objectives of the research were to identify the types of macro algae and to explains the potential use of macro algae in the Pesisir Barat Lampung Region. The study used cruise method. The findings were identified by experts to validate the results of classification, morphology, and qualitative studies regarding the potential use and benefits of macro algae. From the results of this study, 15 species of macro algae were found on Tanjung Setia Beach included; 3 species of green algae (Chlorophyta) consist of Halimeda opuntia L., Caulerpa racemosa F., Ulva lactuca L .; 7 species of brown algae (Phaeophyta) consist of Padina pavonica L., Padina australis H., Sargassum vulgare C.A., Sargassum polycystum C.A., Turbinaria ornata J.A., Turbinaria ornata J.A., Fucus vesiculosus L.; and 5 species of red algae (Rhodophyta), consist of Corallina officinalis L., Gigartina pistilla S., Gigartina disticha S., Gracilaria verrucosa, H., Rhodymenia pseudopalmat J.V.L.The benefits of this research for society to provide insight into the potential use of macro algae which can be utilized in many fields. For students, provide information on the biodiversity of macro algae in the sea.
This research is an experimental research, which aims to determine the effect of variation dosage in of organic pineapple liquid waste fertilizer, on the growth and productivity of red lettuce (Lactuca Sativa L) and its potential as learning resources of biology learning. This research uses a Completely Randomized Design with 1 control and 3 treatment combinations and 5 repetitions. This research was conducted for 30 days. The parameters which is used in this research include plant height and wet weight of lettuce (Lactuca sativa L), with supporting data in the form of number of leaves and stem diameter. The main data is tabulated and analysed using the SPSS 25.0 application which includes Multivariate Analysis of Variance. The results of this research can be concluded that the application of organic fertillizer from pineaplle liquid waste has a significant influence on the growth and product of lettuce (Lactuca sativa L). The results of the research be used as a practical guide on plant growth and development materials.
