Abstract
A modulated intensity by zero effort (MIEZE) spectrometer is a type of neutron-resonance spin-echo spectrometer and can be used to analyze the slow dynamics of condensed matter by measuring the intermediate scattering function I(Q,τ). A crucial feature of a MIEZE spectrometer is it leaves completely free the space between the sample and the detector because the sample is placed after the neutron-spin analyzer. Measuring the magnetic dynamics with a conventional neutron-spin-echo spectrometer is difficult, but with a MIEZE spectrometer such a measurement may be done simply by introducing a second analyzer after the sample. Measuring the magnetic dynamics with high precision requires the background to be reduced to a minimum and is a job for which a 3He neutron-spin filter (3He-NSF) is a promising candidate as a second analyzer. However, one difficulty with this approach is the diffusion of 3He gas from the 3He-NSF, which may be measured and interpreted as dynamics. Therefore, we investigate herein whether the dynamics of gas diffusion is detected when using a 3He-NSF as second analyzer in a MIEZE spectrometer. Toward this end, we experimented with the MIEZE spectrometer installed at beamline 06 (BL06) at the Materials and Life Science Experimental Facility at Japan Proton Accelerator Research Complex (J-PARC MLF). The results confirm that the gas-diffusion dynamics of the 3He-NSF are not detected, and that the 3He-NSF, therefore, can be used as a second analyzer in this MIEZE spectrometer.

Abstract
The Spherical Neutron Polarimetry (SNP) Technique probes complex magnetic structures which are inaccessible by other methods. This technique is achieved by combining a zero-field sample chamber with full control of incoming and outgoing neutron polarization. While wide-angle SNP capability has been fully implemented in Europe, it is still in development in the US. At Oak Ridge National Laboratory, we are developing a wide-angle SNP capability suited for multiple neutron beamlines. The design is based on the basic concept of SNP while utilizing high-Tc superconducting films and Mu-metal. In this article we report our recent development of the SNP capability and its future applications.

Abstract
A full phonon intensity cancellation is reported in a longitudinal polarized inelastic neutron scattering experiment performed on the magnetocaloric compound MnFe4Si3, a ferromagnet with TCurie
≈ 305 K. The TA[100] phonon polarized along the c-axis measured from the Brillouin zone center G=(0, 0, 2) is observed only in one (

) of the two non-spin-flip polarization channels and is absent in the other one (

) at low temperatures. This effect disappears at higher temperatures, in the vicinity of TCurie
, where the phonon is measured in both channels with nonetheless marked different intensities. The effect is understood as originating from nuclear-magnetic interference between the nuclear one-phonon and the magnetovibrational one-phonon scattering cross-sections. The total cancellation reported is accidental, i.e. does not correspond to a systematic effect, as established by measurements in different Brillouin zones.

Abstract
Displaced phase-amplitude variable in polar form. This variable is used to investigate changes in amplitude in complex fields with phases that depend only on the position in the propagation. Soliton on Finite Background (SFB) which is an exact solution of Nonlinear Schrodinger (NLS) equation has been widely used in investigating wave propagation dynamics so that it is the basic for the proposed displaced phase-amplitude. Using displaced phase-amplitude, the results obtained can be described in Argand Diagrams. Wave equation used as a model is the Benjamin Bona Mahony (BBM) equation where the envelope of this wave evolves following the NLS equation. This wave is unidirectional long wave on the surface and has low amplitude characteristics. Step by step to obtain a SFB solution that contains displaced phase-amplitude described and displayed in an argand diagram. In additional, the envelope graph is given.

Published: December 2019

Abstract
Infrared spectroscopy has the capability to determine the mineralogical composition of geologic materials. Its reflectance spectra contain diagnostic spectral absorption feature characteristics that can be used for analyzing the mineral chemistry and chemical composition of volcanic material samples. In this research, we analyze the infrared spectral shapes and properties of volcanic materials at specific wavelength ranges in order to identify compositional information of the samples. We used volcanic material samples such as ash and rocks (tuffs) collected from Sinabung volcano, North Sumatra, Indonesia. Reflectance spectra of the samples were characterized using infrared spectroscopic method. Variation in depth of spectral absorption features and reflectance values of ash and rock samples related to grain size, chemical and mineralogical composition, and surface roughness of the samples. The spectroscopic characteristics showed that these volcanic samples exhibit a strong Al-OH absorption feature centered at ~2200 nm. It indicates that the samples contain predominantly clay or other phyllosilicate minerals. Reflectance spectroscopy can be used to extract compositional information of mineralogy in volcanic material samples.

AbstractThis study aimed to determine the optimum concentration of the glutathione in cryopreservation of African catfishClarias gariepinusspermatozoa. The study was conducted at the Ujung Batee Brackish Aquaculture Center (BPBAP), Aceh Besar, Indonesia. Five concentrations of glutathione were tested in this study using the completely randomized design. These concentrations of glutathione were 0.0, 0.5, 1.0, 1.5 and 2.0 mgL−1. Every treatment was performed with four replications. The results showed that the glutathione gave the significant effect on the sperm motility (P < 0.05), but did not give the significant effect on the sperm viability (P > 0.05). The average percentage of sperm motility after thawing was P0 (39.25%), P1 (28.50%), P2 (39.25%), P3 (34.00%) and P4 (40.50%), while the average percentage of sperm viability was P0 (84.37%), P1 (81.00%), P2 (91.62%), P3 (81.87%) and P4 (92.00%). The highest value of motility and viability were recorded in the in treatment P4 (2.0 mgL−1glutathione). However, these values were not different significantly with concentration of 1.0 mgL−1. Therefore, it is concluded that the optimum concentration of the glutathione for the best sperm motility and viability is 1.0 mgL−1

Published: December 2019

Abstract
Diphtheria is one of the vaccine preventable diseases. Due to the advances in medical technology and vaccine availability, this disease should no longer be a health problem. Its outbreak which reached the highest point in 2017 has opened our eyes that diphtheria remains a major threat, is highly contagious, and leads to morbidity and mortality. The large number of diphtheria cases also indicates that the protection of immunization in the community has decreased. This paper aims to discuss the usage of the reliable official big data namely the Indonesia Health Profile from year 2004 to 2017 released by the Ministry of Health to describe the magnitude of diphtheria in Indonesia. Providing big open data related to infectious disease is very challenging. The released data should be managed properly so it can be used by the government and related institutions to generate better policies and recommendations in order to end the outbreak and provide adequate protection against diphtheria amongst Indonesian community.

Abstract
The use of coal which is dominated by hard coal is projected as the main energy source (± 25%) in 2050 according to the Indonesian Government Regulation No. 79 of 2014. The use of low-rank coal as a substitute for hard coal through the Upgrading Brown Coal (UBC) process is supported by the Indonesian Government Regulation No. 77 of 2014 concerning the obligation to increase the added value of mining products. The use of UBC products can reduce the amount of coal consumption by up to 50% of the use of low-rank coal The UBC process is still being developed, as in this study, a mixture of low-rank coal and waste cooking oil is used as a coating material to cover the coal pores after the watering process. The variation in the mixing ratio of low-rank coal and waste cooking oil is 1:1; 1:2; and 1:3, with a variation of the heating temperature and mixing mixture of 100°C; 125°C; 150°C; 175°C; and 200°C. The analysis showed that the best conditions are found at a ratio of 1: 3 with a temperature of 175°C, wherein the results of the inherent moisture showed a decrease of 21.95% with a calorific value of 7462.82 cal/g. The high calorific value obtained was proven by the flame that occurred for 14 minutes for 50 g of the UBC product sample in the best variable with ash content of 2.92 %, and volatile matter by 64.77%.

Published: December 2019

Abstract
Sumbawa has the potential to transition into a smart city, utilizing solar energy as their main source of its alternative energy. Located in the tropical country of Indonesia, Sumbawa’s dry season lasts eight months, during which it sees a solar intensity of 4.51 watt/m2/h, making solar energy a promising resource for the area. Its level of abundance and no pollution attribute are the main factors that make solar energy an attractive renewable resource. Raw calculation showed that solar energy is able to provide massive amount of energy, while solar panel and photovoltaic can produce zero greenhouse gases when converting solar energy into electricity. However, the high initial cost of installing solar cells hinder popularization of it as an alternative energy source, meanwhile some of the substance materials that compose solar panel may have a negative impact on the environment. This study intends to review the potential for inexpensive semiconductor-based solar panels to be applied as independent source of lighting by analysing the cost and environmental impact. Discussion on simple chemical method without high cost equipment instalment is also highlighted in this work, which offers recommendation of methods that can contribute on lowering the production cost of solar panel.
Urban Planning Simulation Game and the Development of Spatial Competence
Authors: Pramaputri N I , Gamal A 
Published: December 2019

Abstract
The use of simulation has proven to be helpful for many academics from various disciplines in the last decade. In the field of pedagogy, not only does simulation help in learning something new, but it also can be utilized as a learning tool for students. Today, there have been a lot of academic discourse of what kind of competence that can be harvested from the use of simulation. On the other hand, spatial intelligence is one type of intelligence whose existence is foreshadowed by the two more popular intelligence today; verbal and mathematical intelligence. To this day, only a few studies have thoroughly explored how to develop spatial intelligence, but only for children. This lack of dedicated framework and research has produced a consequential impediment for the uptake of simulation use in university-level education, particularly in spatial- oriented subjects. This paper addresses this shortcoming by reintroducing several key information regarding simulation, model, gamification, and its connection to spatial intelligence. This literature review will then be applied to an urban planning simulation game case study of SimCity. The result of this paper shows that there are several types of simulation that can train specific spatial competencies, which will further students’ spatial competence.
