<![CDATA[Learning media is one of the most important component in a learning process, both inside or outside a classroom. In order to provide proper learning for students based on the researcher’s prior research, at least, three different field tests are needed. This research is a quasi-experiment, which is provide result of the second field test of cellulose degrading bacteria from mangrove soil microbiology handout both in cognitive and psychomotor ability. The research aims are to describe effect of this microbiology handout on student’s cognitive achievement and gain data about inappropriate laboratory written instruction in this handout. Data gained by conducting learning activities using developed handout which were 2 times in class theory and three times of practical activity using instuctions written in the handout. In the end of class theory activity, students did a posttest to confirm their improvement of cognitive ability while their practical ability was observed using observation sheet along with their activities. Results showed that handout which being tested could improve student cognitive at average level (n gain 0,419). In contrast, several parts of laboratory written instruction need to be fixed to make better microbiology handout. ]]>

<![CDATA[Bad quality of the questions is one of the factors that can lead to errors in the grading of student learning outcomes. It gives a lower students’ score than the appropriate score and will give an impact on school grades (NS). In this case, school grades (NS) have an effect of 40% in determining the passing of national exams (UN). Therefore, this study was conducted to assess the quality of first semester final exam items made by biology class XII teacher based on some aspects; they are the material, construction, and language. In this study, the researcher used purposive sampling technique in order to collect the data. Items were assessed using a multiple-choice item evaluation sheet which has been declared valid by an expert validator. By combining the material aspects of the assessment data, construction, and language, research results obtained in general show that of the 120 items assessed, there are 104 ( 86,7 %) items with excellent criteria and 16 ( 13,3% ) items with right criteria. Thus, the items made by biology class XII teachers are still suitable for final semester exam of the 2013/2014 academic year Sidrap Regency.]]>

<![CDATA[Bioecology of Coconut crab (Birgus latro L.) On Kaledupa Island, the objective of the research is to know the Biological characteristics (morphometric measurements in the length and width of the carapax, cephlathorax added rostrum (Cp + r) and body weight) and to know the Ecological characteristic (population size) Coconut crab which is on the island of Kaledupa. Sampling technique used the CMRR (Capture-Mark-ReleaseRecapture) method. Data analysis techniques used: (1) Coconut crab morphometry. Data were analyzed descriptively by calculating the average length and width of the carapax, cephalothorax + rostrum length and body weight, (2) Data on sex ratio and population estimation were analyzed quantitatively. Based on the result of the analysis, the highest morphometric measurements are the length of the carapax with an average of 6.37 cm, the width of the carapax 6.03 cm, the length of the cephalothorax + rostrum 10.06 cm, which is located at the location of Station I (Hoga island, Furake sub-village). This is because of this station has unspoiled environmental conditions and there are burrows or caves where the Coconut crab is hiding, where the station belongs to the Wakatobi National Park which is a protected area, and has coconut and other shrub vegetation. These are a food source of Coconut crab s, so this area is ideal for the survival of Coconut crab. The lowest morphometry measurements obtained by carapax length with a mean of 5.62 cm, carapax width of 5.49 cm, length of cephalothorax + rostrum of 9.044 cm, which is found at the location of Station II (Sombano village). This is thought to be the condition of habitats that have been converted into other uses such as the opening of plantation land, so many of the Coconut crab hide outs are damaged. The comparison of male and female sex ratio is 13 Male: 7 Female.]]>

<![CDATA[Curriculum 2013 teachers are required to perform a scientific study. So it's essential to see how the competence of teachers in learning based on a scientific approach. Based on this study aims to describe (1) the ability of science teachers in designing learning based on the scientific approach in SMPN 1 and SMPN 2 Kendari (2) the competence of science teachers in implementing the learning-based approach is scientifically appropriate curriculum, 2013 in SMPN 1 and SMPN 2 Kendari. The collection of data is done (This sentence appears to be written in the passive voice. Consider writing in the active voice) using an instrument study lesson plans, teaching observation, and interviews. The sampling using a purposive sampling method or sample aims. Samples are 13 teacher teaching science classes VII and VIII derived from two schools SMPN 1 and SMPN 2 Kendari. The results showed that (1) the competence of science teachers in designing learning based on appropriate scientific approach was in functional categories, (2) the ability of science teachers in implementing the learning based on proper scientific approach was good enough grade.]]>

<![CDATA[Rhizophora mucronata Lamk. is widely used for rehabilitation of mangrove areas because the fruit is easily obtained, sowing and can grow in areas of high or low tidal inundation. This study aims to know the effect of high-low waterlogging on fecundity (the development of fruit into mature propagules) Rhizophora mucronata Lamk and to determine the characteristics of the ecosystem environment on the Rhizophora mucronata Lamk fecundity. The study was conducted in the Marobo River Mawasangka, Buton Tengah, Southeast Sulawesi. Observations were made in the downstream area towards the headwaters of the river. Each zone is made 100m baseline; the distance between sub-transects is 25m. Each subplot was plotted by making 2x2m2 quadrant plots for Rhizophora mucronata Lamk. earning productive interest, propagules and seedlings, making it easier to count the number of seedlings. Fecundity (counting the number of fruits until the propagules ripen each tree) and measurement of environmental chemical physics. Fecundity comparison analysis between the two zones by using a t-test. The results of the study based on the t-test, there is a significant difference in the percentage of fruit and propagules in zones 1 and 2 with a value of p 0.05, the highest average fruit is in zone 1 (79.9%). The highest propagule average is in zone 2 (33, 9%), highly influential in the high-low of puddles with salinity levels of zone 1 (20%) and zone 2 (10%). The results showed that there was a high-low waterlogging effect on the Rhizopora mucronata Lamk fecundity]]>

<![CDATA[Learning media is one of the tools that teachers use to deliver material to students, so that they can be motivated in learning. Unfortunately, there are some teachers have not used interesting media in order to increase students interest. In this case, one of the effective media is by used interactive multimedia. Therefore, in this study the researcher try to develop the interactive multimedia by using Auto play Media Studio 8 about the diversity of life organization system for VII grade students. The research subject consisted of three biology lecturers in UNP, two science teachers and 30 students in class VII of SMPN 31 Padang. Based on data analysis, the validity value of 80.81% (valid) is obtained, the practicality value of the teachers was 86.60% (practical) and the practicality value of students was 90.91% (efficient). The conclusion of this study was interactive multimedia was valid and functional to use]]>
