This study aims to describe the utilization of Smart Tree Photosynthesis media in science learning in grade V primary school. This research begins from the low learning outcomes of students of class V SDN 11 Air Kalam in science learning with abstract materials. The reason for teachers using more abstract material because the school did not have the appropriate media for learning these materials. Students were uninterested, less motivated, and the learning process did not provide a meaningful experience to students. So the learning outcomes did not reach the specified target. In the early study of science learning with photosynthesis material, only 5 of 33 students who achieve mastery of 70%. The author makes three-dimensional media Smart Tree Photosynthesis as one solution to solve the problem. Based on the results of reflection on two cycles, it can be seen that there was a better activity of student learning outcomes. The grade average value reached 85.76 after the evaluation. So, it can be concluded that the utilization of three dimensions of Smart Tree Photosynthesis media in science learning with the material of making food on green plants is able to improve student learning outcomes, and the lesson presented by the teacher is more meaningful for the students.

The background of this research shows that education for students is the responsibility of parents. The purpose of this study is to analyze the integrative holistic implementation by using the CIPP approach. When the parents work and cannot take care of their children, they trust the caregivers or adults at home without consideration of the caregiver's educational background. The teacher believes that the obligation to care is the responsibility of the family or parents. Teachers in schools are also obliged to teach their children to read, write and count. The integrative holistic early childhood development program has a strong legal basis, namely Presidential Regulation No. 60 of 2013. Thus, integrative holistic early childhood development must be carried out in a special early childhood education unit, such as the Khaira Ummah Islamic Kindergarten in the city of Padang. The obligation to implement an integrative holistic early childhood development program, according to the mandate in Presidential Regulation No. 60 of 2013 as a whole is concluded that even though some programs have not developed optimally, most programs have been managed holistically and integratively.

Education is one of the most important things in human life. It can be categorised into formal and informal education. The former one is carried out in an institution called school. Lately, the issues regarding the low quality of education in Indonesia has been discussed. To date, Public demands on the quality of education have always been highly anticipated by various parties. The quality of education in formal education certainly involves the teacher, as the main foundation for creating high-quality generations. The role of the teacher is inseparable from the teaching profession in improving Human Resources (HR). Currently improving teacher quality can be seen from the performance and professionalism of a teacher which can be done with supervision. Supervision is an activity that is certainly designed to improve the quality of teachers in certain institutions. However, at this time supervision is said to not have a major effect on improving teacher performance and professionalism in carrying out their duties. This can be seen by the teacher only teach well when there is supervision at the time. The effect of improving the quality of education is not experiencing a good quality improvement. The low performance and professionalism of teachers based on teacher competency makes teachers incompetent. This should be done by the teacher without any connection at the time of supervision. Therefore, there is a need for supervision that has an impact on teachers’ performance and professionalism.

Cathepsin was proteolytic enzyme which is found animal tissues included fish. Cathepsin found in fish muscle tissue, cathepsin and other hydrolyzing enzymes were place in subcellular organelles and divided into two places, that was in muscle fibers and extracellular matrix. The aimed of this study was to the characterization of cathepsin enzyme especially catfish. So that in enviromental condition that can increased the activity of cathepsin enzyme an approtiate handling process can be carried out. The method of analyze enzyme activity, while the measurement of protein concentration refered to Bradford (1976). The treatments in this study was determination temperature (30oC, 40oC, 50oC, dan 60oC) and substrate (1.5% 2%, 2.5%). The result showed of enzyme activity with detrmination temperature very influential and fluctuating, the optimum temperature was 30oC where the activity reaches 0.38 U/ml. The best activity treatment of substrate was 1.5% where the activity reaches 0.42 U/ml. BSA Standard curve with regression equation y = 0.95x + 0.109.Keywords: Cathepsin, enzyme, substrate, temperature

Polymer Electrolyte Membrane Fuel Cell with supramolecular structure based on Sulfonated Polystyrene (S-PS) have been developed in Research Centre for Physics LIPI. In forming the supramolecular structure sulfonate groups in S-PS are aligned with polyethylene-graft-maleic anhydride (PE-g-MA) which carried out by dissolution of the constituent and mixing of both. The alignmentof sulfonate groups in s-PS is carried out in a liquid form.Therefore, in this study, the effect of concentration of the solution of both polymersconstituent to the alignment of the sulfonate groups and the characteristics of the membrane produced is studied. Scanning Electron Microscope (SEM) images show that all membranes prepared are rigid. Differential Scanning Calorimetry (DSC) studied show very significance differences in its crystal sizes. XRD diffraction data also support the previous results. Membrane prepared from very dilute solution having better ion exchange capacity (IEC), water uptake and ionic conductivity. Therefore, the experiments results showing that very low concentration of polymer constituent, clearly, produced better interaction of both, which agree with hyphotesis in this work where supramolecular structure can be formed by mixing two very dilute polymer solutions.

Determination of the minimum spanning tree are widely used to solve optimizationproblems of finding solutions to problems that require minmum. In the electricity distributionnetwork, minimum spanning tree (MST) is used to find the minimum length of cable forelectricity network system becomes more optimal. Minimum weight of a MST primarydistribution power network is strongly influenced by the geographical conditions of a region inthe form of contour data. This research was done by designing a model of primary distributionpower network graph in accordance with the data obtained. In finding the minimum weight foreach side of the network graph should include parameters elevation, high point / node, and thedistance between points / nodes. Furthermore, the graph is done by computer calculation andsimulation to get the electricity distribution network primary MST using Prim's algorithm with thehelp of ArcView GIS 3.3 program through the avenue script.Prim's algorithm included in the category of good or efficient algorithms, because theshape of polynomial time complexity in n, where n is a measure of the number of vertices orsides. Based on the test results have shown that the algorithm Prim MST ability to determinethe primary distribution grid is much better if based on the geographical conditions of a region.In addition, Prim's algorithm graph computation time in generating the MST based on the datathat is not based on the contour and contour data are quadratic.Keywords: minimum spanning tree, prim's algorithm, contours, complexity time
