This article presents the results of study in a series of development of learning device with green chemistry insight. The issues that will be discussed in this paper are; "How to design basic chemistry learning experiences to support learning curriculum with green chemistry insight?" The principle method used  consists of three stages: preliminary study supported by reference study, development, and the evaluation by the expert. The results showed that the principle of green chemistry can be raised as an insight on Basic Chemistry lectures both for classroom and laboratory activities. The green chemistry learning curriculum can bring green chemistry insight into the formulation of  learning experiences. Learning experiences both for classroom learning and practicum activities in the laboratory can be given green chemistry insight. The principle of green chemistry that can be raised in the basic chemistry learning scheme, among others, principle number 1 (prevent or reduce the formation of waste) can be raised on the learning experience in the form of practical activities such as on the topic of chemical reactions; principle number 6 (energy efficiency) can be raised in classroom learning on almost any topic; and principle number 12 (creating safe  conditions and preventing accidents) can be generated in laboratory activities on almost all topics. It is suggested that the the principles of green chemistry are possible to integrate in the other curriculum of learning.

 

The result of analysis of semester lesson plan of Basic Chemistry Course with Green Chemistry Insight is presented in Table 1.

(A) two drops (B) one drop

The test of distillation result by using AgNO3 agent to detect the presence of Cl^- ions derived from NaCl added to the liquid prior to distillation. The amount or volume of AgNO3 0.1M used for the test is reduced to half from two drops to one drop (Green Chemistry  principles No. 1 and No.6).

By reducing  number of droplets AgNO3 can still show the detection of the presence of Cl^- ions present in the solution before distilation  process.

Finding, students learning experiences of Basic Chemistry Course can be disigned by integrating green chemistry principles to support curriclum with green chemistry insight. Green chemistry principles can be integrated in classroon learning activities or laboratory activities.

 

Conclusion

The results of this study  showed that the principle of green chemistry can be raised as an insight on Basic Chemistry course both for classroom and laboratory learning.

Student learning experience for learning in classroom or in laboratory can be given green chemistry insight. The green chemistry learning curriculum can bring green chemistry insight into the formulation of student’s learning experiences. The principles of green chemistry that can be raised in the basic chemistry learning scheme, among others, principle number 1) prevents or reduces waste generation, principle number 6) energy efficiency, and principle number 12, creates safe conditions and prevents accidents. The student’s learning experineces are; question and answer about steps of scientific method, create concept maps, doing experiment in laboratory.
