IMPROVEMENT ACTIVITIES AND STUDENT LEARNING OUTCOMES IN READING COMPREHENSION THROUGH COOPERATIVE LEARNING TYPE TEAMS-GAMES-TOURNAMENT (TGT) FIFTH GRADE CLASS ELEMENTARY SCHOOL 8 SOUTH METRO
This research is motivated by the low activities and student learning
outcomes in teaching reading comprehension is lesson. The purpose of this action
research to improve the activity and student learning outcomes in reading
comprehension through cooperative learning type teams-games-tounament (TGT)
in fifth grade class Elementary School 8 South Metro academic year 2011/2012.
This study is a Classroom Action Research (CAR). CAR consists of a series of
four activities carried out in the cycle, namely: (1) planning, (2) implementation,
(3) observation, and (4) reflection. The data were taken by using observation, test,
and documentation. The data analysis of this research is descriptive qualitative
and quantitative of the learning process of students from the first cycle to the
second cycle.The results of the reading comprehension is lesson in fifth grade
class students of Elementary School 8 South Metro through the TGT cooperative
learning from cycle to cycle is increase. Student activity in the first cycle obtained
65.90%, in the second cycle it obtained 78.40% or 12.50% increased. Student
learning outcomes in the first cycle is 68.33, the second cycle increased 5.21 to
73.54. Based on the findings, reading comprehension activities through
cooperative learning tipe TGT is able to improve student learning outcomes.
Researcher recommend to teachers to implement cooperative learning TGT as an
alternative learning method to teach Indonesian as well as other subjects.

Effects Of Aluminium Toxicity On Root Morphology And Physiology Of Two Maize Hybrids
Acid soils in Malaysia account for 72% of the country that was classified under
Ultisols and Oxisols. Crop production is not favorable in highly weathered Ultisols and
Oxisols, due to aluminium (Al) and manganese (Mn) toxicities as well as calcium (Ca)
and magnesium (Mg) deficiencies. Acid soils with high Al saturation (> 60%) induce
water stress and retards plant growth. Al toxicity and water stress affects every aspect
of plant growth, including the anatomy, morphology, physiology and biochemistry.
Therefore, a detail understanding of the physiological characteristics of Al stress, will
lead to improvement of maize (Zea mays L.) with tolerance to Al that can be grown on
Ultisols and Oxisols.
Three experiments were conducted to study the effects of aluminium toxicity on root
morphology and physiology of two maize hybrids (Putra J-58 and C-7). Experiments
were conducted in the laboratory and at Field two, Faculty of Agriculture, Universiti
Putra Malaysia. The experiments were conducted to study the effect of Al on seed
germination, short-term effect of Al on root structure and effect of high Al concentrations on maize growth. The experimental designs were randomized
complete block design in factorial arrangement, and replicated three times.
Overall results showed that maize seeds were impermeable to Al, even though seeds
were soaked in 300 Ī¼M Al for 8 h, the seeds when sliced and stained with 0.2%
hematoxylin showed that the embryo was not stained. Moreover, seed germination
was normal when soaked in Al solution, but after germination, root growth was
restricted and root tip became brown, stubby, with lesions on the root surface. The
total root length of C-7 was significantly longer than Putra J-58.
Hematoxylin staining showed that tolerance level of Putra J-58 was considered as
intermediate tolerance to Al, while C-7 was sensitive to Al. Al uptake appears to take
place within 30 min, and based on the root morphological observations, Al disrupted
root cells within 24 h as indicated by lesions in the cortex tissue of the root tip.
High Al concentrations (278 and 556 Ī¼M Al) inhibited root growth as well as root
branching and induced water stress symptoms. After two days in the Al solution,
leaves showed interveinal chlorosis, a symptom of Mg deficiency and supported by
result of leaf analysis. This symptom was observed on plant grown in solutions with
278 and 556 Ī¼M Al. Ca content in the shoot of maize grown in 0 and 556 Ī¼M Al were
8.81 and 4.41 Ī¼g/g of DM, respectively. Moreover, Mg content in the shoot of maize
grown in 0 and 556 Ī¼M Al were 5.51 and 2.33 Ī¼g/g of DM, respectively. After six
days in the nutrient solution containing 556 Ī¼M Al, root and shoot dry matter
reduced by 61.1% and 34.8%, respectively, compared to control. In addition, stomatal resistance increased by 84.6% and transpiration rate was reduced 41.8% by
556 Ī¼M Al, respectively, compared to control.
Al toxicity induced root lesions, stubby roots and deep-cracking on the epidermal
tissue of the roots. However, the degree of root inhibition or root damage and the
decreasing plant physiological activities were dependent on the level of Al present.
Maize root growth appears to show a linear or almost exponential response to Al
toxicity

Pancasila The Ultimate of All the Sources of Laws (A Dignified Justice Perspective)
Until today in the Indonesian legal system, Pancasila (the Indonesian five tenets) is the first and foremost source of laws. Pancasila has been regarded as the ultimate or principal source of all the sources of laws, which has its legal force to govern the legal system of the Republic of Indonesia. In the past when the nation state of Indonesia had not been formed or was still in a state of divided sub-nations occupying the archipelago, it was considered as the Kingdom of the Netherlandās colony and was known as āHindia Belandaā; the source of law of the Kingdom of the Netherlands was in the main, authomatically regarded as the sub-nations occupying the archipelagoās source of laws. Indonesian jurist must stop making any reference to their system by pointing to sources such as: common law, civil law, socialist law, roman law, canonical law, hamurabi law or religious law which was in force in the past or is currently. However, as the character of Pancasila Legal System is inclusive, reference to the legal systems of any civilised nation can still be made in order to absolve the legal ideas in the other legal system. Key words: Pancasila, The Ultimate Source, law
KEJAHATAN PERTAMBANGAN DALAM PERSPEKTIF KEADILAN BERMARTABAT
Hukum selalu hadir untuk mengatasi kejahatan dan menghadirkan kembali keadilan. Urgensi kehadiran hukum mengatasi kejahatan atau ketidakadilan pertambangan terlihat dalam rumusan UUD 1945 Pasal 33 ayat (3). Bahwa bumi, air, dan kekayaan alam yang terkandung didalamnya dikuasai oleh negara dan dipergunakan untuk sebesar-besar kemakmuran rakyat. Keadilan Bermartabat memotret, menggambarkan dan terutama menjelaskan bagaimana eksistensi hukum mengatasi kejahatan maupun pelanggaran atau ketidakadilan yang selalu mengancam eksistensi dunia pertambangan. Suatu contoh dari gambaran Keadilan Bermartabat tentang kejahatan dan kehadiran hukum untuk mencegah dan mengatasi kejahatan dalam bidang pertambangan dalam sistem hukum Pancasila itu antara lain dapat terlihat manifestasinya dalam rumusan ketentuan dalam UU No. 4 Tahun 2009 tentang Pertambangan Mineral dan Batubara. Gambaran Keadilan Bermartabat tentang kejahatan atau ketidakadilan serta upaya untuk mengatasi kejahatan dan ketidakadilan pertambangan antara lain dapat ditemukan dalam rumusan pasal-pasal mulai Pasal 158 sampai dengan Pasal 165 UU No. 4 Tahun 2009 tentang Pertambangan Mineral dan Batubara.The law has always been around to overcome evil and restore justice. The urgency of the ever presence of law in handling mining crime activities could be seen in the 1945 Constitution of the Republic of Indonesia, Article 33 Section 3. It is stipulated that land, water and wealth of itās natural resources are in the possession of the State and used for the utmost welfare of the people. The Dignified Justice has potrayed, described and particularly explained how the law exists to overcome crimes and offences or injustices which always threaten the mining industries. Among other things, one of the examples ofthe Dignified Justice Theory describes how the law plays itās role to prevent and solve crimes in the Pancasila Legal System which is in the Law number 4/2009 on Minerals and Coals Mining. The details on the types of crimes and offences on the mining field and all the legal efforts to overcome those injustices might be found in the Articles of 158 to 165 of the Law number 4/2009 on Minerals and Coals Mining
