The Design of this Interactive Multimedia is motivated by the increasing number of work accidents that occur in chemical laboratories due to students lack of knowledge of properties about the properties of chemicals and work safety in the laboratory. Based on data obtained from research conducted at the existing SMAN in Temanggung sub-district, it was concluded that the level of student knowledge regarding the aspects of chemicals and work safety in the laboratory was not evenly distributed. Methods in making this application include collecting literature, designing and developing applications, trials and publications. The results of making this application can be used for practician especially students in experiments in chemical laboratories. With this interactive multimedia the Chemical Safety Data based on Augmented Reality can provide convenience in obtaining chemical information and can reduce the risk of work accidents in the Chemistry Laboratory.

Tourism becomes a sector that gets more attention every year by the government, but now the form of tourism and the essence gained is less relevant. Demak Regency has similar problems, lack of varied forms of tourism, the absence of recreational and educational elements to be one cause of the number of tourists who come to be unstable and declining each year. [Demak In Figures 2015]. The form of tourism that is less environmentally friendly is the next impact. The impact on nature that is less guarded sustainability and only concerned with profit alone.Alternative tourism is one of the forms completion taken. Alternative tourism has many advantages that provide a positive impact for the community directly and the environment and also provide educational and recreational value for tourists. Alternative tourism also has a selling point for the potential that exists, one of them potential fruits in the District Demak. Especially guava and star fruit, both the fruit is very abundant and many processed products from both fruit.Agrotourism is an idea chosen as an alternative form of tourism which will support the concept of agri-business center from the existing local government. Agrotourism also as a means of introducing the potential of fruit and agribusiness center to the visitor with the hope that the planned place will live and the standard of living of the local community will increase. To support agrotourism that presents the concept of sustainable tourism, the Eco-architecture is raised to support the objectives of Agrotourism. In eco-architecture there are some basic thoughts that can be a solution of natural damage that occurs due to the form of mass tourism. Eco-Architecture is environmentally sound development, which utilizes the potential of nature as much as possible but still prioritizes conservation, environmental education and welfare of the surrounding community

Nickel oxide (NiO) nanocrystals were synthesized by simple sol-gel method at low temperature by using methanol as the solvent and NaOH 5M as the precipitation agent. Nickel nitrate hexahydrate, nickel acetate tetrahydrate and nickel sulfate hexahydrate were used as the precursors. The crystals were formed by drying at 100-110 °C for ± 1 hour, after which they were heated at ± 450 °C for 1 hour. The resulting products were black powders. The as-prepared NiOnanocrystals were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD patterns of the NiO nanocrystals showed that they are mostly cubic. The sizes of the NiO particles produced with nickelnitrate hexahydrate, nickel acetate tetrahydrate and nickel sulfate hexahydrate were 72.16, 38.63 and 32.84 nm, respectively. SEM images showed that the nanopowders produced by the precursors are spherical, rod-shaped andhexagonal shape with hollow, respectively.

The malachite green dye is one of the harmful dyes produced from various textile industry wastes and needs to reduce by the presence of the waste. The biosorption method is one of the alternative methods used to remove the concentration of malachite green. Biosorption using langsat peel biosorbent proved to be able to absorb malachite green dye. This study using the coloum method by varying the pH of the MG solution and particle size of the biosorbent. In this research, spectronics were used to measure the concentration of the solution and analyze the functional groups on langsat peel before activation, after activation, and after contact using FTIR. Based on the results of the study, it was found that the optimum conditions for each variation were at solution pH 5 with an adsorption rate of 4.962 mg/g and particle size of biosorbent 106 m with an adsorption rate of 15.376 mg/g.
