Creative thinking skills can be trained using board games. This study aims to develop a TITUNGAN board game that is valid, practical, and effective in trained students’ mathematical creative thinking ability. This development research uses the example of ADDIE development as a research method. The subjek in this study were 8 students of SMP Negeri 3 Tanjung Bintang. The research instruments were a checklist questionnaire and a test to test the validity, practicality, and effectiveness. The result of validity obtained an average percentage of 92,67% (more than 90%) which is included in the very valid category and an average percentage of the practicality of 80,9% (more than 80%) which is included in the practical category, while the result of paired t-test that there is a significant difference between the pretest and posttest scores. It can be concluded that the TITUNGAN board game can be valid, practical, and effective to train students’ mathematical creative thinking ability.

This study aims to determine the quality of the river water Gandong using bio-indicators of macroinvertebrates and utilize the results of this study to be used as the building blocks of practical guidance on the subject of environmental pollution junior class VII. The study was conducted in River Gandong Village. Ringinagung, Kab. Mabopane divided into 3 stations. Data obtained from direct observations in the field and laboratory tests. The method used is descriptive qualitative approach that gives an overview of water quality Gandong River. Data were analyzed after identifying the calculating method Family Biotic Index (FBI) based on tolerance index macroinvertebrates.The results of measurements of physical and chemical parameters, such as temperature for each station in the range of 25 ° C-26, turbidity range 27-30 cm, the pH range 7, the current speed 0,16-0,29 m / s, DO 5,8-6 , 1 mg / L. Station II data has physical and chemical parameters lowest, but some aquatic biota able to survive despite the type and the amount is not much in the station I and III. As for the calculation of the FBI, the station I have the 6.39, 6.99 II station, and the station III 6.82. Water quality station I quite bad, but the quality of the station II and III declined to poor interpretation of the FBI. Family macroinvertebrates are most commonly found in every station is family Thiaridae and Physidae. The results of this study can be used as the building blocks of practical instructions Chapter Pollution Junior Class VII entitled "Observing types of animals macroinvertebrates in the river".

<p>Tujuan yang ingin dicapai dalam penelitian ini adalah untuk mengetahui keanekaragaman spesies makroinvertebrata dan kualitas Sungai Madiun dengan menggunakan makroinvertebrata sebagai bioindikator, sehingga hasil penelitian ini dapat digunakan sebagai dasar acuan penggunaan air Sungai Madiun dalam peruntukan kebutuhan masyarakat.<br />Metode yang digunakan dalam penelitian ini adalah biomonitoring dengan bioindikator makroinvertebrata, teknik yang digunakan dalam mengambil sampel adalah dengan teknik purposive random sampling, sampling dilakukan di empat stasiun yaitu bagian hulu bagian tengah dan bagian hilir, pengambilan sampel dilakukan setiap 2 minggu sekali selama dua bulan.Analisis data yang digunakan adalah dengan menggunakan Famili Biotik Indeks (FBI) yang didukung oleh paramater fisik dan kimia.<br />Dari penelitian yang telah dilakkan pada stasiun 1 ditemukan 150 spesies dengan FBI=6,58, yang artinya termasuk kategori kualitas air buruk, dengan tingkat pencemaran terpolusi sangat banyak, pada stasiun 2 ditemukan 279 spesies dengan FBI=6,49, yang artinya termasuk kategori kualitas air sangat buruk, dengan tingkat pencemaran terpolusi sangat banyak, pada stasiun 3 ditemukan 342 spesies dengan FBI=6,64, yang artinya termasuk kategori kualitas air buruk, dengan tingkat pencemaran terpolusi sangat banyak dan pada stasiun 4 ditemukan 51 spesies dengan FBI=6,58, yang artinya termasuk kategori kualitas air buruk, dengan tingkat pencemaran terpolusi sangat banyak. Dari data sampel hewan makroinvertebrata yang ditemukan tersebut di atas terdiri dari 13 famili yang sebagian besar adalah makroinvertebrata yang tahan terhadap pencemaran.</p>

<p>The purpose of the study was to determine the activity and student achievement on the<br />material using instructional media ecosystem crossword puzzle with Talking Stick models. This <br />research is a classroom action research (CAR) conducted at SMP Negeri 1 Kartoharjo, with the<br />object of research students VIIE class with 15 students. Data collection is done is by testing,<br />observation and documentation in the form of a check list. The research process was conducted<br />in two cycles each includes four stages, namely planning, implementation, observation and<br />reflection stages. In the present study showed an increase in activity and student achievement in<br />learning biology. It can be seen from the increase in the number of students who completed the<br />KKM is ≥75. In the student activity before any action there are 3 students (20%), following the<br />cycle I increased to 7 students (46.6%), the second cycle to 13 students (86.6%) completed. On<br />student achievement also increased the number of students who completed the pre cycle, the first<br />cycle to the second cycle. Pre cycle 5 students ((33.3%), after the first cycle of action has increased<br />there are 8 students (53.3%), the second cycle, there were 13 students (86.6%) completed.<br />Improved completeness KKM students make the mean value the average grade also increased<br />from 54.0 to 70.6 before and increased to 84.3. improvement in cognitive aspects seen from the<br />results of the post test showed increased learning achievement siswayang biology. Can be seen<br />from the increase in the percentage of students completeness, ie the cycle I as much as 53.3% to<br />86.6% in the second cycle. Based on these studies it can be concluded that by using a learning<br />model dengann Talking Stick media crossword puzzles can increase the activity of class and<br />student achievement VIIE SMP Negeri 1 Kartoharjo.</p>

The aim of research to determine the diversity and Gastropod that predominate in sub watershed tributary village Gandong Takeran Kerik. Descriptive qualitative research method with type of observational study. Determination and site selection studies using transect sampling method, the size of 1x1 m transect quadrant. Research station at 3 stations with 3 points each station. The data was analyzed after identifying the calculation dominance index and diversity index. Gastropod identification results found 4 genera Thiara, Melanoides, Brotia, and Clea. The highest abundance of gastropods at station II, namely 13.7 ind/m2. Thiara highest dominance index is 0.654, indicating that Thiara mendominansi in sub watershed tributary village Gandong Takeran Kerik. Diversity index of each station 0.617, 0.765, and 0.615, indicating that the diversity of gastropods in sub watershed tributary village Gandong Takeran Kerik is very low. Environmental parameters air temperature 30C - 31C, 28C - 29C water temperature, pH 7 to 7.3, and dissolved oxygen (DO) 5mg /l - 5,4mg /l.
