In today's global era, thinking skills are essential to be mastered by students. This research intended to develop and implement PBL-based worksheets integrated with green chemistry and ethnoscience to improve thinking skills, which included generic science skills and critical thinking skills. These skills were observed through learning outcomes, which were divided into three domains, i.e., cognitive, psychomotor, and affective. The cognitive aspect was assessed through pre-and post-test results, the psychomotor domain was valued through an essay test and observational sheets, and the affective domain was evaluated using questionnaires and observational sheets. This research was conducted with XI graders of MAN I Semarang and SMA Pekalongan. There were three rounds implemented; first, preliminary research which has observed the problems in chemistry learning, particularly on the hydrolysis topic and continued to the development of worksheets, then validated. The next round was the implementation of the worksheets. The N-gain test was used to see the influence of the developed worksheets on the increase in critical thinking skills and generic science skills. The critical thinking scored 0.58 (moderate), while the generic science, which covered scale awareness and logical inference, scored 0.63 (moderate) and 0.73 (high), respectively. A paired t-test results revealed that there was a remarkable increase in the logical inference and awareness of scale. Moreover, the results of the study found that the applied worksheets were practical for cognitive, affective, psychomotor seen from the learning outcomes.

Penelitian ini bertujuan untuk mengembangkan perangkat pembelajaran problem based learning berorientasi green chemistry pada materi hidrolisis garam untuk mengembangkan soft skill konservasi siswa SMA. Metode penelitian ini adalah research and development (R&D). Hasil penelitian menunjukkan LKS yang dikembangkan sangat layak untuk digunakan dalam pembelajaran kimia. Perangkat pembelajaran dapat meningkatkan pemahaman konsep siswa materi hidrolisis garam dengan N-gain sebesar 0,63 (sedang). Peningkatan soft skill konservasi siswa yang berkriteria tinggi sebanyak 35,48 % sedangkan yang berkriteria sedang 64,52 %.This research has aim to developt teaching and learning instrument application on problem based learning which oriented on green chemistry on salt hydrolisys for developing conservation soft skill for student. The method of this research is research and development (R&D). The results showed a very worthy worksheets developed for use in teaching chemistry. Teaching instrument can improve the understanding of student concept of salt hydrolysis matery can get N-gain 0,63 (medium). The improving soft skill of student conservation has high criteria 35,48%. For medium has 64,52%.

The aim of this study is to find company suitable business process modeling by combining between the company's business processes need with SMS needs evaluate sub-system entities of the safety management system that enable to be integrated including safety support devices, Measure the ratio of individual or organizational concern to the built safety system. The value HIRA will be controlled through a data entry mechanism in the form of hazard reporting of all the functions that run the business process. HIRA values are controlled in real time through a computer system so that aspects of risk reduction and increase can be controlled transparently so that mitigation can be done earlier. Integrated safety management system is a distributed risk control effort that can be controlled and monitored jointly all the functions of the organization.

Basically, information system design is fundamental to the long-term sustainability of information systems. Information system architecture is a reference in developing and building new information systems if the current system is no longer able to support the activities of an organization or company. There are various information system development methods and there are various information systems architecture models. The choice of using methods and models must be carefully considered so that the information system created is right on target. A variety of techniques will be introduced to enrich knowledge in choosing development methods and architectural models that suit the needs of the organization.
