Effect of water-cement ratio on fracture energy based on work of fracture
Authors: Arianti A D , Muin R B , Patty A H 
Published: May 2020

Abstract
Concrete is brittle material which generally consists of many micro cracks which are a potential source of crack propagation which leads to possible catastrophic failure and resulting fracture of concrete structures under service loads. The relationship of fracture energy to material properties has not been clearly identified, with most studies showing a relative insensitivity to the water-cement ratio, and concrete cracks propagate mainly along the aggregate-cement interface. This research is an experiment about the effect of water-cement ratio on fracture energy based on the RILEM method. The fracture energy is measured by testing under three bend points with the notch depth ratio is 0.25 and loading rate is 0.05 mm/sec using a closed-loop testing machine to produce load-displacement curve. Concrete used crushed stones with a maximum size of 19 mm which was tested at 56 days of age and has a water-cement ratio (w/cm) of 0.30, 0.40 and 0.6. The correlation between fracture energy and water-cement ratio are insensitive to each other. This can be seen when concrete containing a lower water-cement ratio (0.3) tends to have increased compressive strength but decreases fracture energy.

Published: May 2020

Abstract
Renewable energy utilization is recognized as a way to increase energy access for rural and remote areas. However, such efforts depend not only on the economic and technological aspects but also the support of society and respective stakeholders. Some studies have focused on managing stakeholders in wide scope energy projects but studies in relation to rural electrification program (REP) schemes seem to be lacking. To help understand the wider scope of rural electrification, this paper analyses a range of past and current research development on this domain and places the literature on the framework of stakeholder management (SM). The review indicates that SM in relation to REP is identified under three major themes namely stakeholder influence, stakeholder identification and classification, and stakeholder involvement.

Abstract
In Balikpapan the growth in the number of hotels increased significantly over the past 10 years but the income earned from this sector has tended to decline. Currently, it is found that hotel development growth becomes imbalance due to overcapacity and only exist in several regions. This study aims to identify hotel distribution patterns and hotel location clustering analysis based on the occupancy rate conducted in two stages using the Average Nearest Neighbor (ANN) and hot spot analysis method. In overview, hotels in Balikpapan, both star hotel and non-star hotel, significantly clustered spatially around the centers of urban activities. This grouping is not linear with the occupancy rate distribution pattern. The occupancy rate pattern of star hotels shows a spatially clustered structure with z-score to 2.69 (most significant). Conversely, the occupancy rate of non-star hotels has a random pattern with a z-score is closest to 0 (not significant). However, in general, the constructed hotels in an area which has high accessibility and closes to urban centers is the hot spot point for significant high occupancy rates.

Authors: Bima W I W K , Suryani V , Wardana A A 
Published: May 2020

Abstract
Narrowband-IoT is one of the emerging LPWAN technologies in the market. Traditionally asset tracking employs Global Positioning System (GPS) and General Packet Radio Service (GPRS) connections to send telemetry data to database servers. Compared to GPRS, NB-IoT has a smaller power usage, given proper implementation. This paper discusses NB-IoT implementation in asset tracking applications. Our test includes these parameters: latency, throughput, packet loss, and power usage for both technologies. The result obtained showed that NB-IoT was underperformed in HTTP but in UDP test, NB-IoT showed better power consumption compared to GPRS (0.352 W vs. 0.542 W) even though both have similar uplink throughput (around 350 B/s). From these findings, this new cellular standard is deemed appropriate in the Asset Tracking application, given the correct protocol and architecture.

Abstract
Data confidentiality is an important aspect of information systems. In case of that we need an application to maintain data confidentiality. This study aims to compare two methods of data security systems, namely using the RC4A algorithm which is a symmetric key cryptographic algorithm and the RSA algorithm which is an asymmetric algorithm with a hybrid process on the RC4A and RSA algorithms to secure the secret key of RC4A and speed up the encryption process of RSA. The study uses a comparative test on two algorithm methods, according to data security system parameters. Data is encrypted with the RC4A algorithm and the RC4A key obtained from KSA RC4A will be encrypted with RSA before sending to the receiver. The test results get Hybrid cryptosystem RC4A-RSA faster in completing the encryption process than RSA. Furthermore, the RC4A key can be secured by being encrypted using the RSA algorithm.
