Abstract

The purpose of this study is to predict the number of traffic accident victims who died in Timor Tengah Regency with Trend Projection method and Backpropagation method, and compare the two methods based on the degree of guilt and predict the number traffic accident victims in the Timor Tengah Regency for the coming year. This research was conducted in Timor Tengah Regency where data used in this study was obtained from Police Unit in Timor Tengah Regency. The data is on the number of traffic accidents in Timor Tengah Regency from 2000 – 2013, which is obtained by a quantitative analysis with Trend Projection and Backpropagation method. The results of the data analysis predicting the number of traffic accidents victims using Trend Projection method obtained the best model which is the quadratic trend model with equation Yk = 39.786 + (3.297) X + (0.13) X2. Whereas by using back propagation method, it is obtained the optimum network that consists of 2 inputs, 3 hidden screens, and 1 output. Based on the error rates obtained, Back propagation method is better than the Trend Projection method which means that the predicting accuracy with Back propagation method is the best method to predict the number of traffic accidents victims in Timor Tengah Regency. Thus obtained predicting the numbers of traffic accident victims for the next 5 years (Years 2014-2018) respectively - are 106 person, 115 person, 115 person, 119 person and 120 person. Keywords: Trend Projection, Back propagation, Predicting.

Abstract

The lack of teacher creativity to design teaching and learning activities by applying various teaching methods suitable for the characteristics of the students' subject matter, situation, or condition is one of the problems in learning. This community service aims to support educators in Noemuti District, North Central Timor Regency, in carrying out activities to compile learning tools based on field trip learning methods, carry out learning in the classroom, and write scientific articles. The plans for this activity are training and mentoring strategies. Exercise is related to planning, action, observation and evaluation, and reflection, while mentoring is carried out outside this training activity according to the needs of learners in the field. Participants in this training came from teachers in the Noemuti sub-district, including elementary, junior high, and high school teachers. The material provided in this activity is related to the field trip learning method, the preparation of learning tools based on the steps of the field trip learning method, simulation of teaching and learning activities both in the room and out of the classroom. The results achieved in this service activity where teachers with different educational backgrounds can be guided in preparing learning tools based on field trip learning methods, and implementing them in class, making scientific articles to be published. In addition, although quantitatively, this activity still does not provide maximum results, qualitatively, these teachers are helped by the learning practices carried out by the service team. They can then be used as an alternative teaching model that can be implemented in their schools.

Abstract

The low concept understanding ability of students in class XI MIA 4 SMA Negeri 9 Kupang is the reason for researchers to conduct research. This study was conducted to describe the improvement of the ability to understand the concept of linear program in students of class XI MIA 4 SMA Negeri 9 Kupang by applying the discovery learning model assisted by interactive powerpoint media. The method used is Classroom Action Research (CAR) which refers to the Kemmis & Mc Taggart model with 4 steps, namely planning, action, observation and reflection. Data collection was done by observation and test. This research was conducted in class XI MIA 4 SMA Negeri 9 Kupang with 32 students. The results showed that the average result of concept understanding test at the end of cycle I was 67.5, then increased to 77.2 in cycle II. Classical concept understanding of each indicator also increased from cycle I to cycle II. The teacher activity score reached 100 in cycle I and cycle II. In addition, the student activity score also increased, namely 92.5 in cycle I and reached 100 in cycle II. Thus, it is concluded that the use of discovery learning model assisted by interactive powerpoint can improve students' concept understanding on linear program material

Abstract

Kegiatan Pengabdian ini dilakukan dengan tujuan untuk membantu guru-guru SD Negeri Binilaka, Desa Oeltuah, Kecamatan Taebenu, Kabupaten Kupang dalam melakukan pembelajaran di kelas agar dapat membuat atau merancang dan menggunakan alat peraga sebagai salah satu media pembelajaran matematika. Kurangnya kemampuan guru-guru SD Negeri Binilaka dalam merancang media pembelajaran berupa alat peraga matematika berbasis lingkungan secara umum masih rendah, namun pada kenyataannya penggunaan media pembelajaran berupa alat peraga dalam meningkatkan pemahaman konsep matematika bagi siswa khususnya SD kelas rendah menjadi salah satu faktor penting dalam kegiatan pembelajaran di kelas. Penggunaan alat peraga berbasis lingkungan sangat memungkinkan siswa memahami konsep matematika akan lebih baik karena alat peraga yang digunakan berada di sekitar siswa. Sasaran kegiatan ini adalah guru SD Negeri Binilaka sebanyak 11 orang dan siswa SD kelas rendah sebanyak 18 orang. Metode yang digunakan pada kegiatan ini adalah ceramah, diskusi, tanya jawab. Selain itu dilakukan pendampingan sebanyak 3 kali, sedangkan pelatihannya sebanyak 3 kali. Secara kuantitatif hasil kegiatan ini menunjukkan sebanyak 85,55% guru sangat puas dengan adanya kegiatan pelatihan pembuatan alat peraga matematika dan pendampingan pembelajaran dengan menggunakan alat peraga. Sebab, dengan pelatihan seperti ini dapat meningkatkan pemahaman siswa terhadap materi pelajaran matematika.
