Indonesia is prone to a variety of natural disasters, one of which is earthquakes. Earthquakes are detrimental to human life, causing among other things a loss of shelter. As such, victims of earthquakes need basic assistance in the form of shelter, which the Indonesian government provides in the transition phase of emergency responses. Several innovations in the provision of temporary shelter have arisen in terms of packaging and fast unloading. This research aimed to examine the effective value of OTTV energy (overall thermal transfer value), differences in room temperature, and thermal comfort in existing temporary shelters. OTTV values and thermal comfort are adapted to Indonesia's humid tropical climate, which has a temperature ranging 24–30°C and air humidity of 75%. Temporary shelters were simulated with Rhinoceros and Grasshopper softwares. The simulation was carried out in two stages, with the first stage simulating the temporary shelter materials and the second stage simulating according to a predetermined standard. The results concluded that the effective value of OTTV with the use of Styrofoam-based shelter gives a value of 27.63 W/m2 with a decrease of up to 4.70 W/m2 and the temperature drops to 2–3°C.

Texture Reconstruction

The shadow-mapping and ray-tracing algorithms are the two popular approaches used in visibility handling for multi-view based texture reconstruction. Visibility testing based on the two algorithms needs a user-defined bias to reduce computation error. However, a constant bias does not work for every part of a geometry. Therefore, the accuracy of the two algorithms is limited. In this paper, we propose a high-precision graphics pipeline-based visibility classification (GPVC) method without introducing a bias. The method consists of two stages. In the first stage, a shader-based rendering is designed in the fixed graphics pipeline to generate initial visibility maps (IVMs). In the second stage, two algorithms, namely, lazy-projection coverage correction (LPCC) and hierarchical iterative vertex-edge-region sampling (HIVERS), are proposed to classify visible primitives into fully visible or partially visible primitives. The proposed method can be easily implemented in the graphics pipeline to achieve parallel acceleration. With respect to efficiency, the proposed method outperforms the bias-based methods. With respect to accuracy, the proposed method can theoretically reach a value of 100%. Compared with available libraries and software, the textured model based on our method is smoother with less distortion and dislocation.

Data Analysis Result

Critical thinking is one of the most important issues in education. However, based on field observation results it is found that students have low critical thinking skills. One reason is that learning activities in the classroom do not foster students’ critical thinking skills. The purpose of this research study to enhance students’ critical skills by implementing the Problem-based Learning (PBL) method. The research subjects were 29 grade 7 students in a junior high school in Manado. The research method used was Classroom Action Research (CAR), conducted from September 12 to November 3, 2017. The instruments used were diagnostic tests, pre-tests and post-tests, observation sheets, student interviews, checklists by observers and students, and the researcher’s reflection journal. Data results were analyzed using the descriptive qualitative method. The results showed that the implementation of the PBL method was able to enhance students’ critical thinking skills in learning math with the achievement percentage of students who passed the KKM for pre-test and post-test based on the overall data analysis result from cycle one to two showing an enhancement of 22% on the first indicator, 9% on the third indicator, and 2% on the fourth indicator. The second indicator showed no enhancement amd there was a decrease of 8% on the fifth indicator. Therefore, the PBL method is effective in enhancing students’ critical thinking skills through each stage of the method in the learning process.BAHASA INDONESIA ABSTRACT: Kemampuan berpikir kritis adalah salah satu hal terpenting dalam dunia pendidikan. Namun, berdasarkan observasi di lapangan ditemukan bahwa siswa memiliki keterampilan berpikir kritis yang rendah. Salah satu penyebabnya adalah aktivitas pembelajaran di kelas tidak melatih keterampilan berpikir kritis siswa. Adapun tujuan dari penelitian ini untuk meningkatkan keterampilan berpikir kritis siswa menggunakan metode Problem-based Learning (PBL). Subyek penelitian adalah 29 siswa kelas VII di suatu SMP di Manado. Metode penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK), dilakukan dari September sampai dengan November 2017. Instrumen yang digunakan adalah diagnostic test, pre-test dan post-test, lembar observasi, wawancara siswa, checklistoleh pengamat dan siswa, dan jurnal refleksi peneliti. Analisis data hasil penelitian menggunakan metode deskriptif kualitatif. Hasil penelitian menunjukkan bahwa penerapan metode PBL mampu meningkatkan keterampilan berpikir kritis siswa dalam pembelajaran matematika dengan peningkatan indikator satu sebesar 22%, indikator tiga sebesar 9%, dan indikator empat sebesar 2%. Adapun untuk indikator dua tidak mengalami peningkatan dan indikator lima mengalami penurunan sebesar 8%. Dengan demikian, metode PBL terbukti efektif meningkatkan keterampilan berpikir kritis siswa melalui setiap tahapan metode dalam proses pembelajaran.<div><hr align="left" size="1" width="33%" /></div>

This study aims to produce e-modules with a contextual teaching and learning approach that is valid, practical, and effective to increase students' interest in learning. This development research uses the Plomp model which consists of three phases, namely the preliminary research phase, the prototyping phase, and the assessment phase. The prototype trial was conducted on 16 eighth grade students of SMPN 1 Tirtayasa, Indonesia. The research instrument consisted of an expert validation sheet to assess the validity, a student response questionnaire to assess practicality, and a student learning interest questionnaire to assess the effectiveness of the e-module. This research produces an e-module with a contextual teaching and learning approach to increase the interest of junior high school students in learning mathematics in the context of everyday life. Although the increase in student interest in learning is still relatively low, overall the e-modules developed are considered valid, practical, and effective, so that they are suitable for use in learning mathematics in junior high schoolsKeywords: Mathematics Module, Contextual Teaching and Learning Interest in Learning Mathematics
