Authors: Setiawan A , Yunmar R A , Tantriawan H 
Published: August 2020

Abstract
Museum is a place of education and learning in the field of culture and history for all levels of society. As one of the first and largest museums in Lampung, Museum Lampung presents a variety of collections that are conditional on cultural values and are very useful if they can be identified through digital media. Speeded-Up Robust Feature (SURF) and Oriented FAST and Rotated BRIEF (ORB) methods are two examples of feature extraction methods that are relatively robust for object recognition in images by finding key points. Digital media determined by the value of key points in this study are images that are classified as having low intensity with an intensity value of <2250 Lux. This study compares the two methods using the digital object media of museum objects. The image of the museum object is given treatment in terms of rotation, scaling, and cropping to test the durability of the image matching process. In terms of feature matching time, the best time is achieved by SURF with 0.16 seconds in testing of 1/3 image region. Meanwhile, the highest matching percentage was also obtained by SURF method from rotational distortion at an angle of 90 degrees which is 76.79% instead of to 63.79% of the percentage obtained by ORB.

Authors: Suhandy D , Yulia M 
Published: August 2020

Abstract
In this research, we investigated the feasibility of using UV-visible spectroscopy and chemometrics to classify three specialty coffees from Java Island: Java Preanger, Java Sindoro-Sumbing dan Java Ijen Raung. Total of 300 samples of Preanger, Sindoro-Sumbing and Ijen Raung ground roasted coffees were used as samples. Samples were extracted using hot distilled water and diluted. The spectral data was acquired using a UV-visible spectrometer in the range of 190-1100 nm. Unsupervised classification based on principal component analysis (PCA) was applied for original and modified spectral data. Using the original full spectrum of 190-1100 nm spectral data, the plot score of the first and second principal components (PC1xPC2) totally can explain 90% of data variance. It was difficult to separate the origin of Preanger, Sindoro-Sumbing and Ijen Raung using original full spectrum data. However, using modified spectral data in the range of 250-450 nm, the clear separation between Preanger, Sindoro-Sumbing and Ijen Raung was demonstrated. In conclusion, it was highly potential to use UV-visible spectroscopy and chemometrics to classify the specialty coffees from Java based on its origin.

Abstract
Aflatoxin is a dangerous secondary metabolite produced by some species in the Aspergillus genus. Aflatoxin contamination is considered as critical indicator for good quality of agricultural product, due to its carcinogenic effect to human and animal health. The contamination of aflatoxin in maize occurred at pre-and post-harvest stage when the environment condition is optimum for the mycotoxin growth. The contamination is possibly appeared along distribution chain from field to maize storage. However, the high risk of aflatoxin contamination point along maize distribution chain still unknown. Therefore, identification of high risk aflatoxin contamination along maize distribution chain for preventive handling is necessary. In this study, the aflatoxin contamination risk was determined along maize distribution chain, from field to maize storage. This study was conducted in one of maize enterprise in East Lampung. The distribution chain scope starts from harvest in the field until the maize ready to sell to feed company, without drying treatment. The distribution chain point was determined become 3 point: maize field (Point 1), before threshing/corncob in storage (Point 2) and before send to feed company/maize threshed (Point 3). The maize kernel was collected from each point for further analysis. Our results suggested for maize enterprise actor to put concern in maize handling at storage after threshing, especially controlling in environmental storage condition and time storage, to reduce aflatoxin contamination.

Abstract
Corn has its own charm in the agricultural industries, especially in Tanjung Bintang. This crop can be consumed as staples in food and feed industry. In corn production chain, post-harvest requires some special attentions, as its price tends to decrease due to incorrect post-harvest handling. The increase of corn demand must be followed by higher productivity that can be identified from several work elements, which consist of cutting (Ct), transporting (Tr), and milling (Mi). In this moment, the post-harvest process is carried out by both men and women. The post-harvest process of corn was performed when it had been dried on the field. Hence, there is no drying process was needed. The purpose of this study was to determine the fatigue level of corn farmers in post-harvest activities both subjectively and objectively. The objective method used in this study was direct observation in the field by measuring the heart rate using a HRM. On the other hand, the applied subjective method was the SOFI questionnaire data. The results of the questionnaire showed that there were significant differences in the dimensions of physical fatigue, which consists of lack of energy (LE), physical exertion (PE), and physical discomfort (PD) with the general transportation showing the highest fatigue and the lowest was milling. The subjective fatigue dimensions, Lack ofmotivation (LM) and sleepiness (S) did not indicate any significant difference due to the majority of the activities were the physical work. In the objective measurements, the IRHR showed that the highest IRHR value in the transporting and grinding was more than 1.50. This value indicated the work element classified as heavy work. In conclusion, the subjective and objective measurements appointed the transportation (Tr) had the highest level of fatigue.

Abstract
The world is experiencing an increase in population leading to an increase in the percentage of people over the age of 65 years, so the aging of the population will not be confine to developed countries only, but also to developing countries. During the next five decades, more than 80% of the elderly will live in civilized cities and regions, due to the direct impact of urban areas on the quality of life for older people to spend most of their time in their local neighborhoods, and therefore they are sensitive to aspects related to the urban environment surrounding them. In order to assist the elderly to practice their daily lives in an appropriate way and support their aging in the place, the research will focus on the elderly in multi-story housing projects and how to work on, connecting them with nature within these complexes and help them in the successful completion of their daily activities. To achieve this the concept of (aging in place), will be addressed and given the role of landscape that can play in support of aging in place for the elderly. So the research came to study the possibility of achieving this concept in multi-story housing projects, where the concept of (aging in place), and the possibility of achieving it by landscape. It will be studied through an extensive literature review for addressing a holistic theoretical framework for indicators related to landscape and how they contribute to achieve aging in the place at the level of multi-story housing projects. Finally, the research reach the locally possibility of benefiting from that framework and diagnosing the obstacles to achieve those possibilities to provide landscape that can assist the elderly in multi-story housing projects achieve ageing well in a convenient and comfortable place for this important segment of the society.

Abstract
The frozen architectural heritage products refer to the products that cannot be repeated or continued for more time. This phenomenon caused by many factors such as inability to use, inadaptability, unrepeatability, collapsibility and the products classified as masterpiece. This paper adresses this phenomenon as a negative power inside the traditional urban fabrics. The main question is how the impact of this negative power could be reduced. This paper conducted a questionnaire to evaluate the architectural heritage products in Alkadhemiaa city in Baghdad. A large part of its fabric has been removed and the local architecture of Alkadhemiaa city has been affected negatively. The results obtained showed that the loss of this heritage fabric could have been avoided.
Sustainable Environment in Interior Design: Design by Choosing Sustainable Materials
Authors: Alfuraty Ali Basim 
Published: August 2020

Abstract
The process of designing interior environments has witnessed in recent years a shift in design strategies that have adopted the provision of healthy and sustainable environments, relying on choosing eco-friendly building materials and appropriate design solutions in interior spaces, creating environmentally responsible architecture and interior design.
Many studies showed that despite the development of the concept of sustainability, many architects, designers, and even users do not adopt sustainable design strategies, especially concerning the choice of sustainable materials in the processes of design, construction and even furnishing. The most important criteria in the choice of such materials and products are the low footprint and environmental impact, the high and easy maintenance, as well as durability, budget, comfort, safety, and flexibility.
The present paper aims to explore the role of the interior designers and the users in promoting the concepts of sustainability in interior spaces, by the proper choice of materials and design solutions to preserve the environment and achieve the users’ optimal interaction with their surrounding spaces.
The results show that the process of promoting and enhancing the interior environments with sustainable materials is a shared responsibility of both interior designers and users. Interior designers should develop solutions to raise the aesthetic and performance level of sustainable materials, as well as encouraging the concerned parties (users) to provide materials and furniture that comply with the concepts of reuse and recycling, to finally raise the level of environmental sustainability of interior spaces, and achieve the health and wellbeing of occupants, building a better and more sustainable future.

Authors: Mohammed Aymen R. , Al-Qaisee Ghusoon S. , Rashid Bushra 
Published: August 2020

AbstractThe multi-storey steel building widely used due to its light gravity loads that is very useful for regions of low soil bearing capacity. Also easy of manufacturing and erecting make it a right choice comparing with other structures. In the last years, the Halabja earthquake may classifieds as the largest base excitation that causes a rapid change in the Iraqi seismic map. Therefore, the aim of the study is to investigate the steel building behaviour under Halabja earthquake loading using a non-linear time history analysis and comparing the results with those obtained from linear static analysis depending to the ISC 1997 and the modern seismic standard ISC 2017. A non-linear analysis using a time history approach was carried out for varied steel multi-storey building models. These models were analysed and designed under dead, live, wind and seismic loads using Staad Pro V8i Software. Results shows that the Iraqi Seismic Code (ISC) 2017 is a good approach to predicting the base shear and the story drift comparing with time history analysis under Halabja earthquake loading, while the Iraqi Seismic Code (ISC) 1997 seems to be very conservative approach.
