Abstract

The economy is sphere of public work and the set of relations that form in the system of production, distribution, exchange and consumption. The paper examines the digital, cyclical, environmental and regional aspects of a cyclical digital environmental regional economy. The digital direction of the economy uses digital twins and robots as assistants to improve its quality, productivity and efficiency. The cyclical economy uses savings and profits to boost its competition and development. The environmental direction of the economy maintains the viability of the environment. The regional economy increases diversification and capacity of local production and preserves the environment in its territory regardless of the type of economic activity. Cyclical aspects of the economy of self-sufficiency mainly concern the financial round-up, and the closed reproduction cycle. Business models of cyclic reproduction realize its economic self-sufficiency. At present, Russia, China, the United States and EU integration education have achieved the optimal level of national economic self-sufficiency. Russia, the United States, and the EU have the necessary financial and human resources. At the same time, China, with excessive human resources, is pursuing a policy of expansion into developing and underdeveloped countries. The main reason for countries to abandon autarky policies in favor of globalization of research activities is the decline in profit levels. The reason for this situation lies in the availability of cheap labour and favourable economic conditions, and production in countries is therefore cheaper. The reason for globalization and the international division of labour lies in maximizing profits, and autarks in maximizing national production, i.e. self-sufficiency. The unity of the Autarky State must be ensured by the existence of economic, historical, cultural ties, as well as by national equilibrium.

Abstract

The growth of Gresik City is shown by the development of various infrastructures such as settlements, highways, and others. Along with the growth of Gresik City area, an increase in flood inundation due to increasingly dense settlements, decrease of vacant land as an infiltration area in Tebalo Village. Flooding is caused due to lack of development of drainage systems in the area of Tebalo Village.

To normalize Tebalo drainage channel, good planning must be prepared for Tebalo drainage channel system including planning the layout of the channel system, calculating the designed flood discharge for each channel, hydraulics analysis for flood flow conditions and also along high sea water tide conditions, and finally designing the dimensions of the channel. After the channel is normalized, it is expected that the flow would be much smoother so that no flooding occurs.

Abstract

Network Monitoring System (NMS) is a system that is highly demanded internet service provider industry in this fast-developing information technology era. The availability of NMS is the best option to restore the service level agreement as a means to compete with other internet service providers’ competitors. The occurrence of disturbance in the network is often unnoticed by the network administrator. This may lead to a crucial problem in decreasing network quality as the impact of time-consuming in solving the problem. Through the explanation, the writer tried to anticipate by classifying problems using Pareto and integrated Nagios with Telegram Messenger as a notification of disturbance. Nagios has many features such as reports, event handlers, monitoring resources (CPU load, memory usage, status up / down, uptime, data traffic, bandwidth), etc. One notable feature owned by Nagios is blast notification of disturbance. It is a feature that will function when one of the devices is in trouble. This feature will inform the network administrator or authorized person in certain divisions as regards the error network. In this case, the problematic device can be categorized according to the parameters made by the network administrator.

Abstract

It has been known that most the college students face problems in communicating in English, especially in non-English-speaking country. The main cause is the teacher failed in choosing the appropriate approach for students. Further, it is necessary to choose a proper approach for college students for teaching speaking skills. From a philosophical point of view, there are two sorts of teaching approaches. These are the andragogy and pedagogy approaches. Andragogy is used for adult learners, and pedagogy is used for young learners. Seen from their age, students at colleges are positively categorized into adult students. Therefore, this paper aims to investigate the implementation of andragogical approach for teaching speaking skills in the intensive English program of Maulana Malik Ibrahim State Islamic University of Malang. This is qualitative descriptive research that the data collection method is an interview. The result revealed that most the teachers in intensive English program in Maulana Malik Ibrahim State Islamic University of Malang have been applied andragogical approach for teaching speaking skill. Hence, the researcher concludes that andragogical approach is the appropriate approach for the adult learner, especially in teaching speaking skills.

Abstract

Point cloud data reconstruction is the basis of point cloud data processing. The reconstruction effect has a great impact on application. For the problems of low precision, large error, and high time consumption of the current scattered point cloud data reconstruction algorithm, a new algorithm of scattered point cloud data reconstruction based on local convexity is proposed in this paper. Firstly, according to surface variation based on local outlier factor (SVLOF), the noise points of point cloud data are divided into near outlier and far outlier, and filtered for point cloud data preprocessing. Based on this, the algorithm based on local convexity is improved. The method of constructing local connection point set is used to replace triangulation to analyze the relationship of neighbor points. The connection part identification method is used for data reconstruction. Experimental results show that, the proposed method can reconstruct the scattered point cloud data accurately, with high precision, small error and low time consumption.

Abstract

No traffic-signal intersection located on Jalan Serang and Jalan Curug, Tangerang Regency often causes traffic congestion. Many side barriers activities of vehicles inhibit the movement of traffic flow.  The toll-road access, which is not far from the intersection, makes the queue long enough to enter Jl. Raya Serang also affects the performance of the surroundings. The study aims to determine the performance of the above intersection this time, which is measured by the capacity, degree of saturation, speed, queuing opportunities, density, and level of services. Field surveys and further analysis of the calculations that have been carried out show the intersection performance. The peak traffic volume occurred on Wednesday, February 5 2020, at 3877 pcu / hour at 07.00 - 08.00 WIB, with a capacity (C) of 2937 pcu / hour. From the available data, the DS value is 1.32. at the Service level F.

Abstract

Concrete is a mixture of Portland cement or other hydraulic cement, fine aggregate, coarse aggregate, and water, with or without additives (admixture). The naphthalene superplasticizer used comes from the distillation of coal tar and a little from the rest of petroleum, but there is also camphor naphthalene. Where camphor grains contain 250-500 mg of naphthalene. Naphthalene is mostly produced from coal tar distillation, and a little from the rest of the fractionation of petroleum, by the molecular formula (C10H8) and in the form of two unified benzene rings. This compound is volatile, volatile even in the form of solids. The vapor produced is flammable. The purpose of this study was to determine the effect of the use of naphthalene from coal tar waste with camphor naphthalene as concrete admixture, and determine the effect of naphthalene from coal tar waste with camphor naphthalene on concrete toughness, density, water absorption, of concrete compressive strength. It is expected that the use of naphthalene can reduce the use of cement, and reduce water use. But it does not reduce the strength of the concrete so as to reduce costs in making concrete. The variations in the use of camphor naphthalene and coal tar naphthalene are 20%, 30%, 40%.
