Abstract
With the rapid growth of the permeability of distributed new energy and the development of Energy Routers based on power electronics technology, the construction of AC/DC hybrid distribution network based on Energy Routers is expected to become a new development direction of urban power grid. This paper proposes a hybrid AC/DC main urban power Grid and Microgrid interconnection architecture based on a new Energy Router topology and its coordinated control strategy as the basic module of future urban power Grid. In this paper, considering the current situation of land resource shortage in the central area of the city, the new energy generation and energy storage technologies represented by photovoltaic building integration and electric vehicles are considered and connected to the urban distribution network in the form of integrated Microgrid. Considering that the electricity production and consumption patterns of adjacent Microgrids may be greatly different, the interconnection architecture between the main power grid and the Microgrid can be constructed. So in this paper, the Energy Router integrated with AC and DC double busbar and four voltage source inverter, coordinated control strategy is a blend of PQ control strategy and V/f control strategy, based on the disturbance observation method of MPPT control strategy of photovoltaic power generation and the control strategy of energy storage system, it not only make full use of new energy, but also effectively ensure the quality of electricity supply. Simulation and analysis of each model and control strategy were carried out on MATLAB 2016a/Simulink simulation platform, and the results verified the effectiveness and reliability of the proposed Energy Router topology and coordination control strategy.

Abstract
It is of great significance to accurate grasp the operating status of the power transformer and to discover the latent faults existing in the transformer in a timely and effective manner. Aiming at the problems of fewer parameters and lower diagnosis accuracy in power transformer evaluation model, this paper proposes a transformer state prediction model based on multi-dimensional data joint analysis. Comprehensively considering the oil dissolved gas data, partial discharge data, infrared data and environmental information data, we first use the sample case database to train the wavelet neural network, and then use the deep long short-term memory network that considers the time series attention mechanism to predict the parameters. The results are fed into the classifier, and we can obtain the operation result of the transformer. Tested on the actual transformer data, the experimental results show that the method has high prediction accuracy, which provides a reliable basis for maintenance personnel to predict the operating state of the transformer, and has certain application value.

Abstract
The traditional switchgear partial discharge pattern recognition method lacks a certain generalization performance and the recognition accuracy is low, which is difficult to apply in practical engineering. In view of this, this paper proposes a switchgear partial discharge pattern recognition method based on residual convolutional neural network. By adding a residual module to the network to solve the problem of deterioration after the saturation of the network leads to the saturation of accuracy, and comprehensively utilize the shallow and deep features of switchgear partial discharge data fusion learning to achieve pattern recognition. In this paper, through partial discharge simulation experiments of different insulation defect types of switchgear and on-site detection of distribution stations, a sample database of partial discharge data of switchgear is constructed and analyzed. The experimental results show that the recognition accuracy rate of the proposed method is 96.06%, which is at least 20.22% higher than the traditional recognition methods, and with the increase of the number of samples in the training set, the recognition rate is greatly improved. The comprehensive use of the feature layer fusion module and the residual module significantly improves the generalization performance of the model, and it is more suitable for practical engineering.

Published: October 2020

Abstract
We investigate self-avoiding walk models of linear block copolymers adsorbed at a surface and desorbed by the action of a force. We rigorously establish the dependence of the free energy on the adsorption and force parameters, and the form of the phase diagram for several cases, including AB-diblock copolymers and ABA-triblock copolymers, pulled from an end vertex and from the central vertex. Our interest in block copolymers is partly motivated by the occurrence of a novel mixed phase in a directed walk model of diblock copolymers Iliev and Janse van Rensburg (2012 J. Stat. Mech. P01019) and we believe that this paper is the first rigorous treatment of a self-avoiding walk model of the situation.

Published: October 2020

Abstract
The prediction of wind speed plays a key role in the determination of the optimal reserve capacity for different time instants and the reduction of the standby cost of wind power grid. Short-term wind speed prediction can reduce the impact of wind power grid and improve the control of wind turbines. The geostatistics kriging as an unbiased estimation method applied to predict the wind speed in a two-dimensional vertical rectangular grid. The wind data were as a geographical variable considered. We firstly used exploratory methods to examine the spatial variability of wind speed and its dependence on geographical variables. The covariance and variogram models took into account in analysing the spatial structure of wind speed at three different instants of time. Then the product model adopted to fit wind data due to the variogram. The accuracy of the method was assessed through a cross validation. The prediction results were comparable with the observed values. The prediction error was about ±0.15 and the correlation coefficient was about 0.85. This study demonstrated that the kriging method could be success fully used in the short-time wind speed prediction in space and time direction.

Abstract
Sugar overconsumption has been related to nutrition-linked pathologies such obesity, diabetes and other health problems. However, the presence of sugar in processed foods is needed because sugar functions as a flavor generator and can affect the sensory properties. Therefore, this study investigated the effect of the spatial distribution of sucrose and aroma on rheological peroperties and sensory perception of traditional food. To do so, we performed our experiments using kue lapis, a traditional food of Indonesia, which consist of four layers and were designed with the same total amount of sucrose and vanilla aroma but varied in their spatial distribution. Panelist (n=20) rated the intensity of salty, sweet, sour, bitter tastes as well as vanilla aroma intensity and liking for each product. The results showed that products with addition of vanilla aroma having an higher aroma intensity regardless of the location of aroma and sucrose on each layer. In addition, products with added sucrose distributed in only one layer (top layer) and heterogeneous of aroma have an higher sweetness perception (p<0.05).

Abstract
Environmental degradation is increasingly threatened in line with the higher pressure on natural resources in an effort to liven up food production and biofuel energy. Food cannot be substituted by other products and can only be expanded through agronomic technology development, while energy can be generated from various sources, including by converting food into biofuels. Food and energy can be developed in Indonesia that has potential on the local endowment to produce food, generate primary energy (solar, wind, and water), and utilise new source renewable energy. In Indonesia, food and energy can be improved with enormous potency on local endowment to mount food production, produce primary energy (solar, wind, and water), as well as finding a new platform of renewable energy sources. Local or native food and the provision of alternative energy sources can encourage economic activity in local communities and promote bargaining positions in the global economy. Development on local food and alternative energy can be done by paying attention the use of local resource, function and role of community development and local organizations to support rural economic development and sustainable agriculture.

Abstract
Few researchers addressed this issue due to the border area, oftentimes is considered as the zone with a lack of accessibility for clean water, education, health, and so on related to basic rights fulfillment. Nevertheless, people have been forgotten if this area has a high potential to develop state economically, as well as has a risk in particular for developing countries. According to the statement, it is important to examine whether the ASEAN Economic Community (AEC) has an impact on cross border trade development in Indonesia as a developing country as well as ASEAN Member State?. A special region is needed that can describe the conditions of trade relations between the two countries to analyze this research comprehensively so that one of Indonesia’s Border Regions namely North Kalimantan Province is represented by all the border regions in Indonesia and the problem in relation to customs border trade is in the trade in goods to be present. In order to find out the result, it used a normative research method, which is a type of legal research. The last but not least is the result showed that AEC has not been effective for Indonesian border area as a developing country due to the community have trade pattern traditionally, even for Indonesia and Malaysia have agreement on border trade agreement (BTA) before ASEAN established AEC, that pattern does exist. In Sum, AEC does not have a significant impact on improving trade activity in the Border Area of Indonesia.
Socio-economic conditions of transmigrants in Bulungan regency, North Kalimantan Province
Authors: Harihanto  
Published: October 2020

Abstract
This research was conducted to determine the socio-economic conditions of transmigrants placed in the Salimbatu Placement Transmigrant (LPT), Tanjung Buka, and Selimau. The study was conducted using a sample survey and collection methods as well as analyzing secondary data. The sample survey was carried out on 10% of the total number of transmigrant households in the study area. Determination of the sample is done in stages, first determining the sample area of three LPTs at random, secondly setting a sample of transmigrant household heads. The results showed that the transmigrants placed in the study area were not fully prosperous as expected. The indications are: (1) their agricultural production is low, on average only around 216 kg of rice / head of household / year, far below 320 kg of rice / head of family / year according to the poverty line of Sayogyo [1], (2) the income of transmigrants classified as “moderate” when compared with the minimum wage in force in the district of Bulungan in 2015, (3) the reduction in the area of their arable land from the original 1.5 ha / head of household obtained from the government, became only an average of 1, 2 ha / head of family; and (4) the frequency of planting and harvesting rice on average only once a year. The above conditions are mainly caused by: (1) the low fertility status of their agricultural land; (2) irrigation of rice fields which only depends on the tides of river or swamp water; (3) the number of plant pests (wild boar, rats and birds); and (4) still limited or difficult access to and from their territory. The transmigrants try to overcome these obstacles or obstacles in a number of ways: (1) looking for part-time work, and (2) adapting to natural conditions, both culturally (by changing habits in the area of origin) and ecologically. However, not all obstacles can be overcome and not all transmigrants have succeeded in overcoming the obstacles. Thus assistance is needed to help transmigrants improve their welfare, so that the main objective of the transmigration program, namely reducing poverty and improving people’s welfare can be achieved. The assistance needed includes: (1) building a swamp water system, so that trasmigrants can work on rice fields and grow rice throughout the year (for the long term), or provide water pumping machines to irrigate their fields from rivers, due to rivers in the area studies never dry throughout the year; (2) subsidizing the price of fertilizers and anti-pest medicines; (3) building a road network that connects all Transmigrant Settlement Locations in the transmigration area (for the long term), or for short-term assistance in providing water transportation facilities (motorized boats) to the transmigrant group.
The process of economic change of the Papuans in Jayapura

Published: October 2020

Abstract
This paper seeks to explain the process of economic change of the Papuans in Jayapura which tends to be subsistence-oriented in the face of a market economy that came with the wave of transmigration since the 1960s. Amid market economy penetration, Papuans are included in a dual economy where a subsistence orientation to meet domestic needs is still being carried out but at the same time facing a capitalistic market economy so that what follows is only the expansion of subsistence and marginality. History shows that Papuans with a subsistence-based economy find it difficult to compete with price-based markets and a large number of migrants having complex trade networks and more established access to expanses. In addition, the relatively small scale of trade and the lack of technical aspects of trading in a market economy such as bargaining, debts and subscription systems make it difficult for Papuans to collect profits from their trading. The community and the regional or central government responded to this with strategies and policies that provided momentum for the expansion of their commercial businesses. This study then looks at how the strategies and momentum that emerged and utilized optimally by the Papuans to develop their economy and what factors would inhibit or drive it.

Green open space is one important component in developing an area. The proportion of the area of green open space in urban areas based on Law number 26 of 2007 concerning Spatial Planning is 30% of the city area. The green open space is divided into several criteria, namely public green open space and private green open space. Public green open space is open space managed by the government whose use is intended for the community. In addition to the aesthetics of public green open space also functions as an air purifier, guardian of groundwater sustainability, a place for the development of various flora and fauna, also provides economic benefits for the community. Mangrove vegetation has the ability to fulfill the function of the green open space. When developed into an open public heiau space, mangroves can have a positive impact on environmental development. Mangrove vegetation has the ability to minimize the erosion and hydrological standby of the region. Besides, mangroves also have the ability to absorb carbon emissions so as to keep the environment air conducive. Mangroves that are well managed can also create new tourist sites that can improve the economy of the surrounding community.
