Voice pattern recognition using Mel-Frequency Cepstral Coefficient and Hidden Markov Model for bahasa Madura
Authors: Ubaidi U , Dewi N P 
Published: November 2019

Abstract
Voice recognition is one part of an application that allows a device to recognize spoken words by digitizing words and matching digital signals with a particular pattern stored in a device. Spoken words are converted into digital signals by converting voice waves into a set of numbers which is then compared with the voice pattern to identify the words. MFCC can be an alternative method to solve the problem of voice extraction because this method is reliable for recognizing the unique features of human voice. Hidden Markov Model is used to recognize the voice pattern, so it can be used to compare the voice signal obtained from e-learning with the trained voice signal. Bahasa Madura is a regional language used by ethnic Madurese to communicate daily. Currently the number of Madurese people who understand this language is reduced so that the use of Bahasa Madura is also reduced. Therefore, it is necessary to conduct speech recognition research in Madura Language as one of effort to preserve and develop the use of Regional Language. The experimental results show that the average accuracy for testing the system with one model is 85% and the average accuracy for testing the system with multi model is 90%.

Authors: Wijayaningtyas M , Handoko F , Hidayat S 
Published: November 2019

Abstract
The millennial generation has an important role in actualizing environmentally friendly residence. Referring to the behavioural theory, a consumer’s Perceived Behavioural Control (PBC) is one of purchase intention antecedents. Studies revealing the millennials’ control behaviour on purchasing an eco-friendly house, especially in Indonesia, are still limited. Moreover, environmentally friendly housing is still new to prospective house buyers in Indonesia; so, how to control their behaviour toward purchasing behaviour or willingness to pay has not been clearly known. Therefore, this study is conducted to explore the millennial generation’s PBC on an eco-friendly house purchase intention. This is a qualitative research with a phenomenological approach focusing on observing the perceived behavioural control phenomenon of prospective house buyers. The data was collected through a semi-structured in-depth interview with nine prospective house buyers in Surabaya, East Java. This research found that the themes of millennial house buyers perceived behavioural control toward an eco-friendly house purchase intention were ‘perceived difficulty’ and ‘perceived benefit’. The finding implies that housing developers and government should provide convenience to develop eco-friendly houses and be consistent to complete the buildings with facilities; the facilities will especially support the millennial costumers’ sustainable living and the sustainable development in Indonesia.
Strategy in river flood control
Authors: Nurdiyanto N 
Published: November 2019

Abstract
In February 2018, there was a flood due to the overflow of the Cisanggarung River, one of the affected areas is the population in Ciledug Sub-district, Cirebon, West Java, Indonesia. The purpose of this research is to control the flood of the Cisanggarung River. This study analyzes the amount of water flow that flows in the river crossing capacity. The method used is floods routing from rainfall data using Nakayashu hydrological analysis. The results of the analysis show that the amount of discharge for river capacity is 658 m3/s, while the flood discharge is 784 m3/s, so the river capacity cannot accommodate water. The solution is to floods control by building embankments and normalizing river flow from existing waste. With plans to build embankments and normalize the river, the river capacity becomes 940 m3/s.

Published: November 2019

Abstract
Various methods have been introduced to synthesize ZnO nanostructures, however as in most nanomaterial fabrication processes, these methods require sophisticated equipment and relatively high cost. Hydrothermal method has been known as a simple and inexpensive route to produce ZnO nanostructures. Unfortunately, this method takes a long production time in order to produce high quality ZnO hence making it less efficient. In this study, ZnO micro-nano structures have been successfully synthesized via a fast and low wattage microwave-assisted hydrothermal growth. X-ray diffraction and scanning electron microscope characterizations were done on samples. The rapid heating process generated from rotation, friction and collisions of water molecules inside the microwave resulted in faster reaction process compared with conventional hydrothermal method. Due to its time and cost efficient, this method is useful for optimizing the resulted ZnO and its further applications.
