Abstract: This research aims to improve the learning process and to increase mathematics outcomes from the students of class X MIA 1 SMA PGRI Pekanbaru with applied Discovery Learning model. This research is a class action research with two cycle. The subject of this research is the students of class X MIA 1 SMA PGRI Pekanbaru in academic year 2018/2019, which total of participants are 30 students, consists of 15 male students and 15 female students with heterogeneous ability. The instruments used in this research were mathematical learning instruments and the instruments of collecting data. The mathematical learning instruments used include syllabus, lesson plan, and student work sheet, and the instruments of collecting data were observation sheets used to get the teacher and student activity data and learning outcome test used to get mathematics outcome data after learning process. The data analysis techniques used narrative analysis and descriptive statistic analysis. From the analysis of observation sheets, it can be seen that there is improvement of learning process after the discovery learning model being implemented. The data of the student?s evaluation test showed that the students reaches Minimun Mastery Criteria (MMC) of knowledge competency from the basic score to the first test, from the first test to the second test increase from 12 students (40%) become 20 students (66,67%) and increase become 80%. Persentage of students reaches Minimun Mastery Criteria (MMC) of skills competency increase from first test to the second test where the first test 15 students (50%) to the second test 21 students (70%). Based on data analysis, it can be concluded that implementation of discovery learning model can improve learning process and increase student?s mathematics outcome at class X MIA 1 SMA PGRI Pekanbaru in academic year 2018/2019.Key Words: Mathematics Outcomes, Discovery Learning Model, Class Action Research

Abstract

Hoffa Fracture is a fracture at femoral condyle caused by direct injury of the knee at flexion position; there fore the articular surface is broken. Distal fragment of fracture can be displaced or undisplaced. The Hoffa fracture is divided into three types according to prognostic implication. Type I, the intra articular fracture line reaches the supracondyle of the femur and some of the soft tissues still attached to the distal fragment. Type II, intra articular fracture without any attachment of the soft tissue to the distal fragment. and type III where the fracture line slight anteriorly and proximally to the condyle of the femur with some attachment of the soft tissues and ligaments to the distal fragment. A case of young motor cyclist who involved in collision against a bridge is reviewed. He has type I Hoffa fracture Which is equal to grade III B Gustilo classification system. The conservative procedure of open wound management and skeletal traction was adequate. The problem was that, the radiographic interpretation was difficult if the anterior part of the femoral condyle was intact, undisplaced or slightly displaced. Therefore CT-Scan and tomography were indicated. In type I and type III Hoffa fracture, some soft tissue structures remain attached to the distal condyle fragment and that there will be some blood supply to this fragment. However, in type II fracture the soft tissue may completely be unattached especially type II C and it could predispose to avascular necrosis or nonunion.Key Words : Fracture - intraarticular - femoral condyle - avascular necrosis - non-union

Abstract

Seven patients of open tibial fractures type III C were treated in the Emergency Unit, Sardjito hospital from 1990 to 1995. Three patients underwent early amputation and four patients ultimately required secondary amputation from three to twelve days after vascular repair intervention.Open tibial fractures associated with vascular trauma need an immediate decision between early amputation and limb salvage. Prospective studies are important before a well-defined protocol or objective criteria for early amputation can be considered.Key word : open fracture – tibial fracture – lower fracture – type Ill C – amputation

Abstract

Telah diselidiki pengaruh nikethamide terhadap sleeping time phenobarbital pada 8 ekor albino rat, strain laboratorium sendiri; di mana terIihat perpanjangan sleeping time pada suntikan nikethamide 10 menit sesudah suntikan phenobarbital.Juga terlihat perpanjangan sleeping time pada female rat bila dibanding dengan malerat.Oleh karena itu dalam penggunaan nikethamide sebagai antidoturn keracunan barbiturat masih diragukan sesuai dengan pendapat sebagian buku, dan untuk lebih rnemastikan nikethamide adalah kontra indikasi perlu pengumpulan data klinik yang lengkap

Abstract

The amputation and reconstructive procedure of the management of open tibial fracture type III is still of interest and controversy because the amputation effort is considered as a punishment of primary treatment but a reconstructive method in massive lower extremity trauma is difficult. The MESS is a scoring system that can be applied to mangled extremity and help one determines which mangled limb will eventually come to amputation. The record of 28 open tibial fracture type III patients had been reviewed at the SARDJITO hospital 1990-1995. All seven open tibial fracture type Ill C patients with MESS of greater than seven were amputated. According to four tables of blind comparison analyzing MESS value those patients of more than seven was found to have a positive predictive of 100 % that may be best treated by primary amputation. In conclusion the MESS is an early and accurate predictor for identifying the extremity that may be best treated by amputation or reconstruction.Key words : open fracture - MESS - tibial fracture - amputation - mangled extremity

Abstract

All open fractures especially open fracture of the lower leg grade III A and III B, should be assumed to be contaminated, therefore they tend to be infected. The time of intervention is one of the risk factors of infection complication.A descriptive analysis has been conducted aiming at evaluate the occurrence of infection and the time of treatment on patients with open fracture of the lower leg grade III A and III B. In this study 102 cases (80 males and 22 females) who had open fracture of the lower leg grade III A and III B were admitted to Dr. Sardjito General hospital, Yogyakarta. Patients were evaluated according to the inclusion and exclusion criteria. Out of fifty-four cases underwent intervention before 8 hours after injury (within golden period) 25 cases (46,29%) had been infected. The rest (48 cases) who had treatment after 8 hours since trauma, 83,33% (40 cases) were infected.A statistical analysis (X2 = 13,520, df=1 and p < 0,001) showed that there was significant difference of infection complication of open fracture of the lower leg grade III A and III B and the intervention between within and beyond golden period.Key words: open fracture - tibia fracture - infection - golden period - debridement

Abstract

This study was aimed at determining appropriate time interval of providing liquid organic fertilizer Enviro to growth and yield of two varieties of cucumber and interaction betweenthe time interval and the variety.  The experiment was carried out on flood plain of Krueng Lamnyong, Shiah Kuala Sub District, Banda Aceh from November 2008 to January 2009, using a factorial randomized complete block design 4x2 with three replications. Factors studied were time interval of providing liquid organic fertilizer Enviro, consisting of 4 levels ( 5, 7, 9 and 11 days and varieties, consisting of 2 levels (local varieties and Hercules 56). Variables observed were plant height, fruit numbers, fruit length, fruit diameter, and fruit Weights. Results showed that the time interval of providing liquid organic fertilizer Enviro did not affect plant height at age of 10, 20, and 30 days after planting (DAP), the number, length, diameter and weight of cucumber fruits harvested for 4 times. On the other hand, variety exerted significant effects on plant height at age of 10, 20 and 30 DAP, the number, length and weight of fruits, but did not exert a significant effect on fruit diameter. The best growth and length of cucumber fruits were found on varieties Hercules 56, while the number, diameter and weight of fruits of four Time harvest were found on local varieties. There was no significant  interaction between time interval and variety on all variables observed.
