Problem-based learning to develop students’ character in biology classroom

Development of students’ character in learning processes is important as weel as the effort to improve students’ cognitive and skills. In biology learning, development of students’ character can be conducted by applying the appropriate teaching strategy. Problem-Based Learning (PBL) is one of the teaching strategies which is potential to develop students’ character. This research was a quasi-experimental design to uncover difference of character development by applying PBL compared with direct instruction (traditional learning). The research samples were 72 first year students in Faculty of Mathematics and Natural Sciences, Universitas Negeri Makassar, Indonesia. Students’ character development was measured by using questionnaire at the beginning and at the end of study. The students’ character was also measured by observation sheet of character during lab session. Research finding indicated that there was no effect of teaching strategy on the students’ character development measured by questionnaire. Different finding was indicated by result of observation, the students taught by PBL showed more increase of character compared with traditional strategy. Based on the fact, lecturers should use PBL to develop students’ character. Others, the future research can consider usage of more accurate measuring instrument of character like behavioral observation sheet by paying attention on its limitation

STUDI EKSPERIMEN BENTUK KACA PENUTUP UNTUK MENINGKATKAN PRODUKTIFITAS DAN EFISIENSI SOLAR STILL

Based on the previous research, it’s needed a research on the development of solar distillation model. The development of a concrete absorbed plate with fin has been conducted and resulted on improving productivity and efficiency of solar still. The development is continued by making a model using the glass covered model with roof shape and V. Experimental method is used in this work. Absorbent plate from concrete with fins models and some gravel are used in this solar still research. The concrete composition is determined by two parts of iron sand and one part of PCC cement. The cover glass design is determined by roof model, V model and conventional model (flat model). Water volume is designed as varied variables. The results show that V model can increase the productivity of freshwater and efficiency of the solar still compared with roof model and conventional model under different water volume. The absorber plate temperature, water temperature and cover glass temperature satisfy the solar radiation pattern. Keywords: solar distillation, cover glass shape, water volum

PentaHelix Synergy on Tourism Development in Batu, East Java

Tourism in Batu, a city in East Java, has developed rapidly and requires involvement from various stakeholders. This research related to the actual implementation of tourism development, using exploratory studies of the ‘Penta Helix’ concept, defined below, which was carried out to compile a complete picture of the idea. A qualitative approach deepened archival understanding and developed observations and interviews with field actors. PentaHelix involves synergies, in this case to develop the tourism sector. There is a ‘PentaHelix’ or collaboration of five elements; namely government, academia, private, media and environmental institutions. However, several weaknesses were found in this synergy, namely the role of academics and environmental institutions. They are called weak points due to a lack of synergy in maximising their roles. The realization of the desired tourism development is a model of synergising tourism development with ‘inter-helix’ cooperation. Academics and environmental institutions need to increase their performance, to synergise tourism development with a PentaHelix perspective in Batu. Moreover, they can build symbiosis between tourism and a PentaHelix perspective in general, to develop tourism itself through the synergy of various elements in the helix. This research provides a new course, to preserve cultural heritage through a PentaHelix collaboration to develop tourism
