Notwithstanding that many efforts to overcome environmental problems have been carried out by several parties, yet the issues still occur. Improving students’ responsible environmental behavior (REB) can be an alternative to solve environmental problems. This study aimed to analyze the relation between the both variables (i.e. naturalist intelligence and personality) and students’ REB at SJHS 51 of Bandung. The research was carried out using quantitative descriptive method through a correlational approach. Naturalist intelligence, personality, and REB data were collected using questionnaires. The research data were analyzed using multiple linear regression at α = 0.05. The research results showed that there was a relation between: (1) naturalist intelligence and REB;. (2) personality and REB; and (3) the both predictor variables and REB. Therefore, empowering the both competencies (naturalist intelligence and personality) is the essential step to improve students’ REB.

Instrument is one of the supports of learning success. Assessment of student knowledge will encourage students to get better grades and will have an impact on increasing student knowledge. This study aims to develop the instruments of critical thinking skills and the ecosystem concept mastery. The instruments produced were an essay test adopted from Facione and a multiple-choice test adopted from Anderson Krathwohl. This research was conducted on September 2018 - October 2019 with 37 tenth-grade students as the sample. The research method used was the 4D model (Define, Design, Develop, and Disseminate), however this research did not do the disseminate stage due to the limitation of time. The results showed that the instruments are feasible with the results of expert validation of 81.03 and 85.00 respectively. Based on the results of the study, it can be concluded that the developed instruments could be used to measure the critical thinking skills and mastery of concepts. However, these tests must be developed further in large classes with more students.

Lakes and waterfalls are freshwater ecosystems having important roles in ecology, tourism and economic aspects. Among living organisms existing in lakes and waterfalls is neuston. Neuston lives on the surface and below the surface of the waters. Neuston can be used as a bioindicator for water quality due to the neuston’s high level of sensitivity toward pollutants. The purpose of this study was to determine the density and diversity of neuston as a bioindicator for water quality in the lake and waterfall. The methods used were survey and observation. The study was carried out by using purposive sampling at two locations, namely the lake and waterfall of Situ Gunung, Sukabumi, with a sampling area of 1 x 1 m2. The samples obtained were put into bottles containing 70% alcohol to be identified in the laboratory. Environmental parameters measured were air and water temperature, water pH, water depth, turbidity, water flow velocity, dissolved oxygen, substrate and weather conditions. The results obtained indicated that the lake and waterfall of Situ Gunung, Sukabumi had highest neuston densities were shown by Gerris lacustris and Dineutus assimilis. The lowest neuston densities were shown by Metrobates hesperius, Gerris comatus, Aquarius remiges and Trepobates pictus. This study showed that the environmental parameters of the lake and waterfall of Situ Gunung, Sukabumi can still support the survival of the existing neustons.
