Published: December 2019

Abstract
One of the strengths of the RADEC learning model is that learning focuses on teaching and problem-solving skills, so in other words, RADEC is a learning model that can develop students’ Higher Order Thinking Skills (HOTS). Learning steps of RADEC consisted of 5 steps which were very easy to remember because they were in accordance with the name of the learning model itself, namely: (1) Read; (2) Answer (A); (3) Discuss (D); (4) Explane (Explain) and (5) Creat (C). At each step of learning RADEC, it can develop HOTS. Students must be able to explore and engage in the learning process so that students’ higher-order thinking skills can be honed. In RADEC learning, each stage can develop high-level student skills including the step of Read. HOTS can be learned in this step by giving the widest opportunity for students to explore and find information from various sources both print and internet. The step of Answer, HOTS can be taught by asking students to look for various alternative answers and solutions. In the Discuss Stage, HOTS can be taught by not limiting students in submitting guesses, ideas, or opinions. The Explane Stage, HOTS can be taught by presenting and communicating the results of the agreement group answers honestly and responsibly, and the other groups will respond to it. While the last stage was Creat, in this step, HOTS can be taught by asking students to provide solutions with their creativity. The results showed that there was an increase in students’ HOTS from an average of 41 to 84.6 after learning with the RADEC learning model.

Hybrid of Particle Swarm and Levenberg Marquardt Optimization in Neural Network Model for Rainfall Prediction
Authors: Warsito Budi , Santoso Rukun , Yasin Hasbi 
Published: December 2019

Abstract
Neural network model has undergone many modifications from the original model through the development of network architecture and optimization methods. By default, the gradient-based optimization method is a method used to find network weights. But some of the weaknesses and limitations of these methods inspired many researchers to try to use other methods. Non-gradient based heuristic method is a reasonable choice considering the learning algorithm in artificial neural networks is inspired by the characteristics of creatures so that optimization methods that also mimic life patterns in nature will be appropriate. One disadvantage of the heurisic method is the length of the iteration process. In this paper, a method which combines heuristic optimization methods and gradient-based methods is applied, namely particle swarm optimization (PSO) and Levenberg Marquardt. The weight obtained from the PSO method becomes the initial weight for the Levenberg Marquardt method. The proposed procedure is applied to the rainfall data in Cokrotulung Klaten. The results showed that this procedure succeeded in providing better predictions than the Levenberg Marquardt method.

Abstract
The presence of saline or salt water in the Jakarta groundwater aquifer is still widely debated by various geologists and groundwater experts. This study intends to identify the cause of the high salinity of groundwater at Tanjung Priok and Koja, North Jakarta. The First Horizontal Derivative (FHD) method of gravity data is applied to identify the direction of subsurface fluid flow. It is also supported by groundwater sample data and self potential (SP) data. The direction of fluid flow on the FHD contour map is indicated from low to high FHD value. From gravity data, Bouguer density values obtained in the study area were 2.12 gr/cm3. This study focuses on surface aquifers so that it is necessary to separate regional and residual anomalies. The results show that the direction of fluid flow is from north to south, there is a high FHD value that is distributed around the coordinates (709000, 9322000) which may indicate as the salt depositions of sea water intrusion.
