This study aims to: 1) examine the challenges teachers encounter in implementing project-based learning in 2013 curriculum, 2) to examine teachers' strategies in integrating project-based learning in 2013 curriculum. This research finds several obstacles faced by teachers and strategies that can be done in the implementation of project-based learning, they are: 1) the obstacle in terms of students' capability can be overcome by familiarizing them to complete projects; 2) the obstacle in terms of indiscipline can be solved by optimizing the teacher's role as supervisor; 3) the time constraint is overcome by some alternative ways; 4) the obstacle in terms of equipment availability is addressed by modifying projects; 5) the obstacle in terms of student's inequality is overcome by forming propori sembang group; 6) the cost issues are resolved by using classroom cash or selecting projects suitable for the available resources. Another positive finding is that teachers should have the confidence and commitment in implementing project-based learning. Based on these results, it can be concluded that most teachers and even experienced teachers will experience difficulties and challenges when trying to implement project-based learning. However, experienced teachers have strategies to overcome obstacles, thus project-based learning can still be implemented.

Local wisdom has been associated with environmental conservation. How local wisdom and social practice shape determine environmental conservation is apparent in the the communities living along the rivers in Banjarmasin Sasirangan. Based on a qualitative approach with case studies of Sasirangan craftsmen. In Sasirangan Village, Banjarmasin City, this study aims to analyses the correlation between social interaction, local wisdom, and environmental conservation Sasirangan. The informants are craftsmen and Sasirangan traders. The data was collected through observation, interviews with craftsmen and Sasirangan traders, as well as documents study. This study concludes that the social interactions occur between craftsmen and craftsmen, craftsmen and groups of craftsmen, and between groups of craftsmen by collaborating in making Sasirangan products and competition in determining the color, motif and Sasirangan marketing. In this process, local culture plays a key role in the form of Sasirangan cloth which has various colors and motifs with certain meanings which are continuously produced, preserved and passed down from generation to generation This creates a mechanis of social interaction and local wisdom that promotes environmental conservation through the cooperation between craftsmen in the manufacture of Sasirangan products using natural colors from nature that are environmentally friendly. By not using chemical coloring, the practice reduces the pollution of river environment in Sasirangan Village, Banjarmasin.

So if the society destroys Repong Damar it is believed that it will be miserable and will get a bad disaster. The strategic adaptability that society does to keep Repong Damar stay sustainable.

Human behavior can cause watershed problems, in which the use and carrying capacity of the watershed do not correspond. The objectives of this research are to determine the land use conditions and carrying capacity of the watersheds, and to analyze this capacity based on changes in land use and flood vulnerability areas. The research was conducted in five watersheds flowing are in flood-prone areas of Semarang City, namely Babon, Banjir Kanal Timur, Garang, Silandak, and Beringin, with a research area of 48,994.62 Ha. A quantitative analysis approach was used to calculate the land-use change and watershed carrying capacity; the capacity variables included land conditions, water quality, population, water building, and watershed space utilization. The results show that 1) an average of 12.27% of land in each watershed unit has been converted into settlements, with the most extensive conversion being in the Banjir Kanal Timur watershed; 2) the carrying capacity of this watershed got 113 scores, which fell into the poor category; and 3) at the watershed level, the surge in land conversion into settlements correlates with the carrying capacity of the watershed. Conversion of land into settlements is one of the determinants of the carrying capacity of the watershed. If the land use arrangement in the watershed is made with consideration of flood-vulnerability areas, this will be able to reduce watershed damage and reduce the frequency of floods.
