Abstract

Moodle learning media based blendedlearning which jad integrated with discovery learning model with a purposive to learn abouthuman reproductive system with online based learning. Moodle based learning (bioshare.my.id) had analyzed and it had achieved a validity and practical measurement. This research had used EDDIE model, analysis, design, development, implementation, and evaluation. Product assessment by using two expert validatort such as assessment instrumental consist of syllabus, lesson plan, moodle, teacher and student response questionnaire. Assessment results from expert validator proved that product which had discovered was feasible because the syllabus validity value was 4,86; lesson plan (RPP) was 4,70; student worksheet (LKPD) was 4,90; moodle was 4,82, teacher response questionnaire was 4,93; and student response questionnaire was 4,90 (strongly valid). Media practical had gotten by teacher response with a value was 89,94 (strongly practical) and student response was 70,20 (practical). Based on the research result concluded that learning instrument and moodle based online learning media which had developed was valid and practical

Abstract

This research applies problembased learning(PBL)with deductive-inductive approach to the course of ordinary differential equation (PDB). This study aims to apply problem-based learning steps involving the student's deductive-inductive thinking approach, applying the teaching materials of PDB involving the student's deductive-inductive thinking approach, but it is also expected that these teaching materials can maximize the deductive-inductive thinking approach, and help students improve their way of thinking, based on the material characteristics of PDB.The research method used is classroom action research, to maximize the deductive-inductive thinking ability of the students. As the paradigm of class action research, the implementation of this research includes planning activities, actions, observation and cyclic reflection, the implementation is divided into two cycles, the first cycle is for two months or seven meetings, and the second cycle is also for two months or seven meetings in the Semester Academic Year 2016/2017, which amounted to 30 students, at Mathematics Department FMIPA UNM Makassar.The results of the first cycle of this study show that problem-based learning with deductive-inductive approaches helps a lot of students, even though at first the students still seem unwilling to apply how their mindset in learning and solving problems. After being given some strengthening, in the following weeks the interaction of learning progressed significantly. Learning scenarios and teaching materials as guidelines for the implementation of lecturing activities, in line with the tendency of the student's deductive-inductive thinking approach. In the second cycle, it shows that improving student’s interpretation of PDB problems, which solved by using deductive-inductive approach, progressing, methods of solving problems made by the students getting better,the results of this study also show that there is improvement of student achievement in PDB, there are 21 students get satisfactory and very satisfactory value, while unsatisfactory value is only 9.

Abstract

Kemampuan awal memiliki peran yang sangat penting baik dalam mengkonstruksi pengetahuan yang baru dipelajari, maupun mengelaborasi pengetahuan tersebut dengan yang telah dimiliki sebelumnya. Bagi pengajar, pengetahuan tentang kemampuan awal peserta didik dapat menjadi acuan dalam menetapkan titik awal pembelajaran, pendekatan dan teknik mengajar, serta program-program penunjang pembelajaran. Secara umum, pengetahuan awal mahasiswa dapat dipengaruhi oleh beberapa faktor mulai dari latar belakang pendidikan, kondisi ekonomi, lingkungan sosial, hingga kondisi geografis daerah asal. Dalam penerimaan mahasiswa Jurusan Matematika FMIPA UNM beberapa tahun terakhir, pihak jurusan berusaha merangkul calon mahasiswa dengan latar belakang yang cukup beragam. Proses tersebut dilakukan dengan menerapkan tiga jalur penerimaan yakni SNMPTN, SBMPTN, dan Ujian Tulis Lokal dengan juga memfasilitasi calon mahasiswa yang kurang mampu secara finansial melalui jalur Bidikmisi. Perlu diketahui bahwa ketiga sistem penyeleksian tersebut menilai calon mahasiswa tidak hanya dari kemampuan matematikanya saja, melainkan pada kemampuan dasar mereka secara menyeluruh, serta jejak prestasi baik akademik maupun non-akademik selama di SMA.

Abstract

Hybrid rice is the result of the development of local snacks as an alternative staple food. In this study, the materials used are cassava (Manihot esculentra) and pumpkin (Cucurbita moschata) with a ratio of in 1 kg is 60:40, 50:50, and 40:60 using thread method. The purpose of this study was to determine the content of water, ash, fat, protein, fiber and carbohydrates in hybrid rice produced. The results showed that the best ratio of cassava and pumpkin was 50:50 in which the protein, fat, water, ash, fiber and carbohydrate content were 3.25%, 0.1%, 6.49%, 2.17%, 4.6%, 71.89%, respectively. This suggests that the hibryd made from cassava and pumpkin can be used as an alternative staple food with nutritional value quite similar with the common rice.

Abstract

This research aims to test osmosis of potatoes (Solanum tuberosum L) and carrots (Daucus carota L) by soaking the two ingredients that have been peeled the skins with table salt (NaCl), where table salt (NaCl) as soluble material and water as the solvent. Meanwhile the comparison is water for soaking it is not added with salt. The research method used in this research is a descriptive qualitative approach, namely the presentation of data in the form of depictions of observations in the form of words. Data were collected by experiments and documentation. The focus of the research was on the texture and color of potatoes after being put into a glass filled with water only and a glass filled with water and salt to prove the process of osmosis.

Abstract

This study aims to determine levels of vitamin C and white dragon fruit (Hylocereus Undatus). The experiment was conducted with the determination of vitamin C with iodimetric method (direct titration). The results showed levels of vitamin C and white dragon fruit on day 5 is 29.406, on day 10 was 26.591, on day 15 is 19.594, on day 20 is 16.847, on day 25 is 13.157. Based on the levels of vitamin C, then obtained a reduction rate of 0.4385 x 10-1 which proved levels of vitamin C and white dragon fruit is first order.

Abstract

This research discuss a SEIR mathematical model of online game addiction. The data used is primary data of the number of students in Junior High School 3 Makassar who are addicted to online game which obtained by share the questionnaires to students. This research starts from constructing a SEIR model of online game addiction,determining the equilibrium point, analysing the stability of equilibrium point, determining the basic reproduction number (푅0), doing a simulation of model using Maple, and interpreting the result of the simulation. In this paper we obtained a SEIR mathematical model of online game addiction; two equilibrium points which are addiction free and addiction equilibrium point; the stability of addiction free and addiction equilibrium; and the basic reproduction value푅0=0,089indicates that there is no transmission of addiction from one individual to another.

Abstract

Corn (Zea mays L) is a cereal crop that has economic value and can be developed as a main source of carbohydrates, vitamins and minerals, as well as animal feed and industrial raw materials. In North Sulawesi, many local varieties of Manado yellow maize have been developed, which are unique in that they taste sweet, have high rice yield, and are resistant to storage. However, at the farmer level, the productivity is low, around 1-2 tonnes/ha. Therefore it is necessary to conduct research to increase the growth and production of local Manado yellow maize with the appropriate application of urea fertilizer time. The results showed that maize had the highest leaf area, dry weight, leaf area index, plant growth rate, and net assimilation rate in N4 and N5 treatments, namely 3 times urea fertilizer 1/3 when planting, 1/3 plant age 15 days, and 1/3 plant age 45 HST (N4) and 1/3 when planting, 1/3 when the plants are 30 days old and 1/3 plants are 45 days old. The highest dry weight was 3.24 t ha-1 in the 3 times application of fertilizer, namely 1/3 when planted, 1/3 when the plants were 30 HST and 45 HST. Thus, the application of 3 times fertilizer application resulted in the highest growth and production of local Manado yellow corn. Further research needs to be tested at locations with different heights.
