Abstract

SMAN 13 Semarang is one of the schools in Semarang that develops waste management as an extracurricular activities. However, students at SMA N 13 Semarang are still seen littering, using plastic as food wrappers, and have not sorted out garbage. Students are expected to have high awareness to contribute to reducing environmental damage by participating in waste management. This study aims to examine the extracurricular potential of waste management in developing the environmental caring character of the students. This research uses qualitative approach with case study research type. The number of primary informants is 15 students who are active in extracurricular waste management. The results showed that students have basic knowledge about the environment through the subject of PLH but have not been able to develop it. Curiosity has been formed because students have an interest in watching television shows and reading environmental related articles, but in terms of providing information media is still limited through teachers. Students throw garbage at the place provided, but to sorting garbage still less. Based on the results of research and discussion can be concluded that the characters that have been formed is used to maintain the cleanliness of the environment, used to dispose of waste in place, the school provides cleaning equipment, and responsible for maintaining environmental cleanliness. Character that has been formed and still requires teacher assistance is the character to sort out garbage, provide communication media and explore knowledge about the environment.

Abstract

Biology was a branch of Natural Sciences (IPA) that studies living things and life. Biology learning will be more meaningful when learning can be done outside the classroom. The results of observations conducted at Jakenan Senior High School, showed that biology learning activities more often use student textbooks. This causes students to be less active in expressing their opinions because they only listen to the teacher's explanation. One model that can be applied to the material of environmental change was the Problem Based Learning (PBL) model. This study aims to determine the effectiveness of PBL learning models on student learning outcomes and environmental care attitudes on material changes in the environment. The research population was used all students of class X Science at Jakenan Senior High School in the academic year 2017/2018. The research design used Quasi experimental with the Nonequivalent control group design. The sampling technique uses purposive. So that we got class X IPA 1 as the control of class and class X IPA 3 as the experimental of class. Cognitive learning outcomes were obtained from the pretest-posttest score. Scores of students' environmental care attitudes were obtained from the questionnaire scale of environmental care attitudes. While psychomotor learning outcomes were obtained from students' psychomotor assessment sheets. The results of the analysis of research data with t-test showed that learning outcomes and environmental care attitudes of students in the experimental of class differ significantly compared to the control of class. While the results of the n-gain test on cognitive learning results show the average value of n-gain in the experimental class was 0.68 higher than the control of class which was 0.48. The results of this study indicate that the application of the PBL model to the material of environmental change was effective towards learning outcomes and environmental care attitudes of high school students.

Abstract

Pekalongan Regency of Central Java is a region with high risk of disaster. Various kinds of disaster such aslandslide, flood, drought, and tidal flood have somehow become “seasonal customer” for occurring inPekalongan Regency. This research aimed to prepare the mapping of disaster risk in order to strengthen theefforts in reducing disaster risk in Pekalongan Regency. The research method applied in this research refers tothe Head’s Regulation of National Risk Management Agency Number 2/2012. Since the risks of tidal flood werenot yet included in the regulation, the field observation approach was used in this research. The analysis ofdisaster risk also considered the collecting method of disaster history by organizing focus group discussion(FGD) with the related parties. The research result showed that there were high risks of flood disaster coveredsome sub-districts such as Kajen, Kesesi, Wonopringgo, Karangdadap, Tirto, Wiradesa and Wonokerto; therewere twenty six villages in total. High risk of landslide potentially occurred in large part of villages on the southarea of Pekalongan Regency. High risk of drought was relatively evenly spread in the center area. Lastly, highrisk of tidal flood potentially occurred in fifteen villages along side of Java Sea.

Abstract

Tuber plants are sources of carbohydrates which could be used as strategic national food reserves. Beside high carbohydrates, tubers also contain a number of bioactive compounds which have physiological effects as antioxidants. This research aimed to develop tuber flour products and increase additional value through the use of appropriate technology and diversification of processed products. Research samples were 16 tuber species. The method was crystallisation by utilization of blower system to accelerate the process of water content reduction. The data were analyzed using proximat analysis. Water content was 5.61-15%, ash content was 0.4-5.31%, carbohydrate content was 82-88%, protein content was 0.67-6.32%, and fat content was 1-7%. The result showed that chemical content of Suweg flour with pragelatinization method at 70ºC for 60 minutes had the highest water, ash, and fiber content which were 5.79%, 2.49%, and 43.73%, respectively. Meanwhile, the highest carbohydrate content obtained by heating for 10 minutes was 25.80%. Tubers flour is worthy to be used as raw materials for food industry.

Abstract

The coastal region is a dynamic area as a transition between the land and the sea. The ecological function of the coastal area is affected mainly by the structure and composition of vegetation factors. This study aims to analyze the vegetation stratification of terrestrial to marine ecosystems in the coastal area of Semarang City, Central Java Indonesia as an effort to manage a sustainable ecosystem. A striped path combined with nested plots were applied in this research. The plots were placed by systematic purposive sampling based on the homogeneity of vegetation found along with the topographic conditions of the research location. Analysis of qualitative data used by way of inventorying plants and identifying plants based on morphological characteristics that can be observed. Data analysis was performed based on the results of an inventory of the structure and composition of vegetation obtained including the index of diversity, evenness, and species richness. The results of plant identification found in the three locations recorded 51 plant species consisting of 29 families. The different types of vegetation in Taman Lele, Tapak, and Tirang Beach affect the diversity, richness, and evenness index of vegetation in all three locations. Therefore, it can be concluded that different environmental factors contribute to the vegetation stratification from the land to the sea. This is the first report on the Semarang coastal area vegetation stratification. The results can have a positive impact on the coastal area conservation strategy for sustainable management, as well as to be a media for environmental education purpose.
