In Indonesia found about 450 species of Anura representing about 11% of all species in the world, and 28 species ofwhich 28 live in West Java. Anura animals have a pattern of calling behavior that is essential for mating: males produce call-up behavior that attracts females and, in some species, represents the extent of their territory. Research on frogs and toads is considered necessary considering the absence of more detailed data on the bioacoustics of these frogs, especially in the West Java area, so that variations and patterns of anura sounds are known in the Telaga Warna Nature Reserve and Nature Park (CA-TWA) area and can make scientific contributions in information on variations and sound patterns owned by anura animals in terms of anura conservation in Indonesia. This research was conducted from month March-December 2018, located in Telaga Warna Nature Reserve and Nature Park, Bogor, West Java. Call the recording every 6:00 p.m. to 11:00 p.m. each night during the sampling period. The number of anura species in the villa and swamp areas is more abundant than the lake area, and the presence of Pearl maroon frogs (nyctixalus margaritifer) found in the villa and lake areas, while the Bufo melanotictus type that likes to live in the lake area. It can be seen that the villa and swamp areas are still maintained vegetation by looking at the medium density of the canopy. Steeper slope conditions help the flow of nutrients from the soil due to the erosion process and settle in flat to gentle areas. The density of the canopy in the area helps maintain the surface temperature of the land with a stable land surface temperature ranging from 15-21 0 C.

This research used the formative evaluation technique, by developing, a prototype of module of teaching material on Human Being, Energy, and Natural Resource as a model in writing other modules. The module was tested and revised gradually, starting from one-to-one evaluation; the small group evaluation; and field evaluation. The result of the research shows that several deficiencies were found in the module prototype on the one-to-one evaluation, such as the less obvious picture with the description written in foreign language, formative test that is not suitable with the material, and some terms that are not clearly explained. The result of small group evaluation also shows that the material on module prototype is too excessive and there are some topics that must be revised. Meanwhile, the result of field test shows that the module prototype is quite good and it can be understood by respondents, but there are still suggestions related to the use of term that is not obvious. It can be concluded that the prototype of teaching material for Environmental Education is quite good to use as the teaching material for distance education after evaluation, revision, and field test, with a little bit the revision especially related to the use of term.

This research adopted a survey method. Food samples were obtained from the traditional and modern markets, elementary schools, and supermarkets available in the region of Pamulang Subdistrict. Sampling was done by using a purposive technique. Each sample was qualitatively analyzed for its borax content using a borax test kit. The detected food was then analyzed by using a qualitative analysis (i.e., there are four categories of data); one sample per category was taken to be analyzed quantitatively using the HPLC method in the Laboratorium of Balai Besar Pusat Penelitian dan Pengembangan Pascapanen Pertanian, Bogor. The treatment of food containing the highest level of borax) was conducted by boiling them during a certain period of time (i.e., 5 minutes, 15 minutes, and 30 minutes) and then frying them until well cooked (was not burnt). The collected data were then analyzed descriptively. The results showed that 54% of the samples obtained from the Elementary Schools positively contained borax; as much as 74% of the food samples obtained from traditional markets contained borax positively; while all samples coming from the supermarkets did not contain borax. The content of borax in the detected food in this research ranged between 560 mg/kg up to 17,640 mg/kg. The highest content of borax found in yellow wet noodles (17,640 mg/kg) was far above the maximum level specified by EFSA (2013), that is as much as 4,000 mg/kg. The boiling process was quite effective in lowering the level of borax in food, while the frying process did not actually reduce the level of borax in food.

They are known to have a good adaptation to high temperatures and poor feed quality. Their meat is one of the protein supplies for the Lakor island local community. Genetic and environmental factors influence growth in animals. Insulin Growth Factor-1 (IGF-1) plays a substantial part in postnatal development, skeletal growth, cell proliferation, and metabolism in the animal. This study aimed to identify the genotype pattern of the IGF-1 gene SNP g.5752 G>C of Lakor goat from Southwest Maluku using the PCR-RFLP method. Sixty-three samples were collected from three villages in Lakor island. The follicle hair samples were taken from the tail and then isolated using a DNA extraction kit. Genotyping of IGF-1 gene SNP g.5752 G>C used PCR-RFLP method with HaeIII restriction enzyme. Results showed that all samples have BB genotype patterns or are monomorphic. It might be caused by the isolation or restricted area in Lakor island and the utilization of extensive rearing systems. This mutation in SNP g.5752 G>C of the IGF-1 gene was not used as a candidate of marker selection in the Lakor goat population.

Introduction Elementary school is the most basic level of education for students taken from grade one to grade six. Primary education is the initial foundation for students to build knowledge to continue formal education to the next level. The progress of a nation can only be achieved through structuring good education. (Nurjanah, 2020). The school needs to be given trust to organize and take care of itself according to environmental conditions (Musdiani, 2019). This deficiency arises due to the lack of attention of educational personnel printing institutions that pay attention to these skills (Waluyandi, 2020). Learning is essentially a cognitive process that has the support of psychomotor functions (Arsani, 2020). As an initial foundation, of course, in elementary school, students must master specific competencies that the government has determined following national education standards. To measure the achievement of existing competencies, the students will be tested with a final exam called UASBN. These questions measure students' competence in three subjects: Indonesian Language, Mathematics, and Natural Sciences (IPA). Until 2016 the questions UASBN tested were still using multiple-choice questions, but since 2017 the UASBN questions have used two forms,

The low critical thinking skills of students in science subjects became the background for this research. The purpose of this study was to determine the effect of the inquiry based learning model and learning motivation on students' critical thinking skills. The research method used in this research is a quasi-experimental in which this research uses two sample groups, namely the experimental class and the control class. The selection of the research sample was carried out using random sampling. The research data was conducted using tests to see critical thinking skills and observation sheets to see student learning motivation. The data obtained were analyzed using two-way analysis of variance (Two Way ANOVA) to analyze the influence between the two variables. The results showed the effect of inquiry based learning on students' critical thinking skills as indicated by a significance value of 0.004 <0.05; there are differences in critical thinking skills of students who have low and high motivation, this can be seen from the significance value of 0.000 <0.05; however, there is no interaction effect between the inquiry-based learning model and student learning motivation as seen from the significance value of 0.736> 0.05.

Four species of Crustacean were selected as sample. Each sample was triple and collected in four sampling periods, east monsoon, transition period from east to west monsoon (transition period I), west monsoon, and transition period from west to east monsoon (transition period II). Lead concentrations of collected samples were tested using flame-AAS. The result indicated that lead concentration on meat of Crustacean was lower than the concentration on carapaces and gills. But each of the concentration was higher than maximum level proposed by CCFAC (1999). Commonly the concentration of lead on Crustacean especially on meat and gills were high during east monsoon, but low during west monsoon.

Introduction Elementary school is the most basic level of education for students taken from grade one to grade six. Primary education is the initial foundation for students to build knowledge to continue formal education to the next level. The progress of a nation can only be achieved through structuring good education. (Nurjanah, 2020). The school needs to be given trust to organize and take care of itself according to environmental conditions (Musdiani, 2019). This deficiency arises due to the lack of attention of educational personnel printing institutions that pay attention to these skills (Waluyandi, 2020). Learning is essentially a cognitive process that has the support of psychomotor functions (Arsani, 2020). As an initial foundation, of course, in elementary school, students must master specific competencies that the government has determined following national education standards. To measure the achievement of existing competencies, the students will be tested with a final exam called UASBN. These questions measure students' competence in three subjects: Indonesian Language, Mathematics, and Natural Sciences (IPA). Until 2016 the questions UASBN tested were still using multiple-choice questions, but since 2017 the UASBN questions have used two forms,

The low critical thinking skills of students in science subjects became the background for this research. The purpose of this study was to determine the effect of the inquiry based learning model and learning motivation on students' critical thinking skills. The research method used in this research is a quasi-experimental in which this research uses two sample groups, namely the experimental class and the control class. The selection of the research sample was carried out using random sampling. The research data was conducted using tests to see critical thinking skills and observation sheets to see student learning motivation. The data obtained were analyzed using two-way analysis of variance (Two Way ANOVA) to analyze the influence between the two variables. The results showed the effect of inquiry based learning on students' critical thinking skills as indicated by a significance value of 0.004 <0.05; there are differences in critical thinking skills of students who have low and high motivation, this can be seen from the significance value of 0.000 <0.05; however, there is no interaction effect between the inquiry-based learning model and student learning motivation as seen from the significance value of 0.736> 0.05.

Four species of Crustacean were selected as sample. Each sample was triple and collected in four sampling periods, east monsoon, transition period from east to west monsoon (transition period I), west monsoon, and transition period from west to east monsoon (transition period II). Lead concentrations of collected samples were tested using flame-AAS. The result indicated that lead concentration on meat of Crustacean was lower than the concentration on carapaces and gills. But each of the concentration was higher than maximum level proposed by CCFAC (1999). Commonly the concentration of lead on Crustacean especially on meat and gills were high during east monsoon, but low during west monsoon.
