Abstract

Creative thinking is high-order thinking that is not easy to stimulate with conventional learning, especially to solve complex physics problems. However, the learning strategy chosen must be in accordance with the teaching materials and students characteristics. Creative thinking is very important especially for low-ability characteristic in solving complicated physics problems; therefore, it needs to be triggered by student-centered learning strategies such as project briefs. This research was to analyze the effect of project brief learning on creative thinking skills (CrTS) of low-ability pre-service physics theacers. Sample was selected using purposive sampling (97 people) in the initial semester pre-service physics teachers which consisted of three classes A (32 people), B (35 people), and C (30 people). Data collection through essay tests on vibration and wave material and adjusted according to the CrTS-Kim indicators. The results show that the project brief has a positive effect on creative thinking skills. The highest effect on the fluency indicator has an average of 15.7 compared to the lecture strategy, as well as the mixture with an average of 9.89, and the lowest on the originality indicator.

Abstract

[Title: Porosity Test and Compressive Strength of Lightweight Brick Based on Gold Processing Waste (LPE) with Banana Tree Filler (FPP)]. Lightweight concrete bricks are made from gold processing waste (LPE) and banana tree filler (FPP) with cement, foam, and clear water. The purpose of making light brick to know the value of porosity and value of compressive strength. Lightweight brick is made with gold processing waste (LPE) and banana tree filler (FPP) consecutively is 250 ml of LPE + 1 layer of FPP, 250 ml of LPE + 2 layers of FPP, 250 ml of LPE + 3 layers of FPP, 250 ml of LPE + 4 layers of FPP . Hardening time is carried out for 22 days in sunlight unspoiled. Tests performed include: density test, porosity test, and compressive strength test. From the test results showed that the porosity value and compressive strength of lightweight concrete bricks with gold processing waste plus the filler of banana trees with the amount of cement in the fixed condition and drying time for 22 consecutive days, the density value 1349, 09 kg / m3, 1290 kg / m3, 1121.6 kg / m3, 1168.3 kg / m3, 1254 kg / m3 and compressive strength value of 2.43 MPa, 1.25 MPa, 1.68 MPa, 2.13 MPa, 1.32 MPa. The high value of porosity and compressive strength value is influenced by the amount of mixture of foam, banana tree filler (FPP) and stirring method

[Title: The Mechanical Test of Lightweight Brick Made from Gold Processing Waste with Variations in Coal and Cement Waste]. The purposes of this research are to make lightweight concrete using waste processing of gold with variation fly ash and cement the better than conventional concrete. The value of this research has tested mechanics which comprises density, porosity and strength. The research has done with some stage are: 1) Make lightweight concrete using LPE with variation fly ash and cement. 2) Characterization of the samples which comprise density, porosity and the strength, 3) Analysis of tested mechanical lightweight concrete. The value of lightweight concrete to make with variation composition fly ash and cement in a series are: (0/100), (5/95), (10/90), (15/85), (20/80) who are in volume. To make lightweight concrete with composition foam and water controlled as much as 10 ml and 150 ml at all of the sample. So we get the density value of lightweight concrete without fly ash is 1.61. In lightweight concrete with fly ash, we get the minimum density of lightweight is 1.15. The porosity value of lightweight concrete without fly ash is 13.6%, and the porosity value of lightweight concrete with fly ash is 8.0%. The compressive strength of lightweight concrete without fly ash is 1.629 MPa and the compressive strength of lightweight concrete with fly ash is 1.772 MPa. The value shown to process waste processing of gold with variation fly ash and cement to be lightweight concrete can get mechanical in character of lightweight to be better than conventional concrete.

Abstract

Research on the manufacture of lightweight brick with basic material waste processing of goldin the province of West Nusa Tenggara has been done. This research is very important because most of the people in NTB separate gold by amalgamation and cyanidation methods. Processes that do this will result in hazardous waste on the environment so that the need for countermeasures. The purpose of this research is to create a lightweight bricks made of waste processing of gold which has a strong press that meets national standards. This research was conducted through two stages, namely 1) Stage of light brick making, 2) Phase compressive strength test light brick production. The results showed that lightweight bricks made with waste raw gold processing and cement with a ratio of 3: 1 has a compressive strength of 7.80 kg / cm2. These results demonstrate compliance with national standards, namely 7.83 kg / cm2 so that the product of this research can be said to be feasible.

Abstract

[Title: Development of Lightweight Brick Based on Traditional Gold Processing Waste with Water Hyacinth Booster]. Research has been carried out on the manufacture of light brick made from gold processing waste with water hyacinth filler. The study was carried out by varying the direction of water hyacinth fiber as filler in light brick making. The direction of the filler is arranged in a horizontal, orthogonal and random direction. In each filler direction, the percentage variation of water hyacinth is arranged with the volume fraction 0%, 15%, 30%, 45%, 60%, from the total volume of the amount of light brick. The test results show that in the horizontal fiber direction the compressive strength is (2.43; 0.25; 0.54; 0.24; 0.50) MPa with a density (1.62; 1.34; 1.58; 1.42; 1.25) gr /cm3. In orthogonal direction the compressive strength was (2.43; 0.26; 0.80; 0.63; 0.77) MPa with density (1.62; 1.42; 1.49; 1.53; 1.42) gr/cm3. While in the random direction the compressive strength was (2.43; 0.73; 0.69; 0.59; 0.65) MPa with a density (1.62; 1.20; 1.41; 1.13; 1, 20) gr/cm3. From these data by comparing with previous studies, the most stable compressive strength and density values are formed in orthogonal directions. While the density value is most formed in random direction. In all directions the compressive strength and stable density were formed in the 60% volume of filler. The test results show that the light brick that is formed into the category is very light (entered in 0.6 - 1.6 gr/cm3 range) and floating in water, with medium compressive compressive strength.
