― The era of democratization requires city leaders to change the development paradigm to be inclusive. This is stated in goal number 11 of the SDGs document, "making cities and human settlements inclusive, safe, resilient, and sustainable", so this study tries to look at the concept of inclusiveness in the scope of settlements, especially in marginal settlements. This study takes place in marginal settlements in the Brantas watershed as Kampung Jodipan which was once a slum settlement but now has been transformed into a Kampung tourism. This openness applies the principle of inclusiveness of the Kampung Jodipan. The data of this research were analyzed with descriptive statistics using Factor Analysis and Cross Tabulation, then the data was validated using triangulation analysis. This study aims to highlight the experience of Kampung Jodipan as a marginal settlement that has succeeded in improving Kampung. It was found that the inclusiveness dimensions in Kampung Jodipan were social inclusion and physical inclusion. Socially, the embodiment of the inclusiveness can be seen through the trust of the community and involving the residents in various activities. Meanwhile, the concept of spatial inclusiveness is manifested with the inclusion of basic infrastructure as a means of meeting the daily needs of citizens.
——民主化时代要求城市领导人改变发展模式,使其具有包容性。可持续发展目标文件的第11个目标“使城市和人类住区具有包容性、安全性、弹性和可持续性”阐述了这一点,因此本研究试图从住区范围,特别是边缘住区的角度来探讨包容性的概念。这项研究发生在Brantas流域的边缘定居点,甘榜Jodipan曾经是一个贫民窟定居点,但现在已经转变为甘榜旅游。这种开放运用了甘榜焦底盘的包容性原则。本研究数据采用因子分析和交叉表法进行描述性统计分析,然后采用三角分析法对数据进行验证。本研究旨在强调甘榜焦地盘作为一个边缘定居点的经验,它成功地改善了甘榜。甘榜焦地班的包容性维度为社会包容和身体包容。在社会方面,包容性的体现体现在社区的信任和让居民参与各种活动。同时,空间包容性的概念体现在将基础设施作为满足市民日常需求的手段。

Rumah susun (walk up flat) are one of the buildings that rely on natural ventilation. However, the application of natural ventilation in rumah susun (walk up flat) in urban areas is influenced by tropical climate problems such as high temperatures and low wind speeds. The design of the openings in the facade has not been able to distribute air into rooms properly. In addition, the layout design makes single-sided natural ventilation the only strategy possible for double loaded corridor type flat. This study aimed to determine the effect of a combination of pivot window designs and wing walls in directing and distribute air into room. The study was conducted in two stages, that was field measurements and experimental with Computational Fluids Dynamics simulations. Simulations were conducted on a combination designs of wing walls and pivot window with 45o and 90o opening angles to determine their effects on the distribution and indoor air velocity. The combination design of wing walls and pivot window created a pressure difference so that it could increase indoor air velocity under both oblique and parallel to the opening. In the direction of the wind that was not oriented to the openings, the combination of wing walls and vertical pivot windows with 90o opening angles increased indoor air velocity up to five times in the corner room. While the 45o opening angle increased the indoor air velocity up to seven times than base case condition in a middle room.
Rumah susun(步行公寓)是一种依靠自然通风的建筑。然而,在城市地区的rumah sussun(步行平台)中自然通风的应用受到高温和低风速等热带气候问题的影响。立面开口的设计无法将空气正确地分配到房间内。此外,布局设计使单面自然通风成为双负荷走廊型公寓的唯一可能策略。本研究旨在确定枢轴窗设计和翼墙组合在引导和分配空气进入房间中的效果。该研究分两个阶段进行,即现场测量和计算流体动力学模拟实验。对45°和90°开角的翼墙和主窗组合设计进行了仿真,以确定其对室内气流分布和速度的影响。翼墙和枢轴窗的组合设计产生了压力差,从而增加了室内在斜开口处和平行开口处的空气流速。在没有朝向开口的风的方向上,翼墙和90度开口角的垂直枢轴窗的组合使角落房间的室内空气速度增加了5倍。而在中间房间,45度的开角使室内空气流速比基准条件增加了7倍。

The high cost of raw materials handling from the port to the warehouses at PT. Petrokimia Gresik has encouraged this research to find solutions to reduce costs in raw material unloading activities. The location of factories and raw material warehouses that are separated from each other, the number of warehouses that are not yet connected with conveyor belts as well as the diverse types of raw materials become its own challenges in operating unloading activities to be more efficient. The layout and allocation of raw materials in the existing warehouses creates high cost of raw materials handling because slow moving raw materials are close to the production location, while fast moving raw materials are far from the production location. In addition, the differences in the existing unloading methods also affect the cost of raw materials unloading, the use of vessel cranes and dump trucks will increase costs, otherwise the use of conveyor belts will minimize the cost of raw materials handling. This research is important to find the layout and allocation of raw materials that have the most efficient handling costs. The steps in this study include (1) data collecting and processing; (2) making conceptual and simulation models, (3) verification and validation tests; (4) developing alternative scenarios; (5) running simulations based on alternative scenarios; (6) comparing scenarios using anova test and cost and benefit analysis. The simulation is done using Arena 14.0 software. The simulation results show that the re-design layout and allocation of 5 warehouses in Factory 2A and Factory 2B is the best alternative scenario. This scenario is proven to be able to minimize the cost of raw materials handling with savings of Rp. 10.958.028.455 per year with an ROI of 108% and a Payback Period of 0,48 years.
从港口到PT. Petrokimia Gresik仓库的原材料处理成本很高,这鼓励了这项研究,以找到降低原材料卸载活动成本的解决方案。工厂和原材料仓库彼此分离的位置、尚未与传送带连接的仓库数量以及原材料的种类繁多,都成为其在操作卸载活动时提高效率的挑战。原材料在现有仓库中的布局和分配造成了原材料搬运的高成本,因为移动慢的原材料靠近生产地点,而移动快的原材料远离生产地点。另外,现有卸货方式的差异也会影响原材料卸货的成本,使用船舶起重机和自卸车会增加成本,否则使用传送带会使原材料装卸成本降到最低。这项研究对于寻找具有最有效处理成本的原材料布局和分配具有重要意义。本研究的步骤包括:(1)数据收集和处理;(2)制作概念模型和仿真模型;(3)验证和验证测试;(4)制定备选方案;(5)基于备选方案进行模拟;(6)运用方差分析和成本效益分析进行情景比较。采用Arena 14.0软件进行仿真。仿真结果表明,工厂2A和工厂2B中5个仓库的重新设计布局和配置是最优备选方案。该方案已被证明能够最大限度地降低原材料处理成本,每年节省10.958.028.455卢比,投资回报率为108%,投资回收期为0.48年。

Abstrak— Flat design has evolved and taken many shapes and forms. Most of the arrangements are arranged in a double-load layout where the units are positioned face to face along the corridor. Another type is two single-loaded flats that are configured to face the courtyard. Building façade also varies from those with shaded surfaces to those with minimum sun protection. Modification in design clearly has an impact on the thermal performance of the buildings. The aim of the study is to investigate the facade configuration on the thermal performance of the building. This study uses simulation software, namely, Design Builder, to predict the thermal performance of the buildings. Several variants of window areas, sun shading, balconies are arranged to explore their effects on thermal performance. Flat with yard selected as a reference model. The results showed that the smaller the window area and the greater coverage given to the window with a shading device, combined with the balcony, can provide a decrease in air temperature up to 0.57 ⁰C, with a reduction in cooling degree hours percentage of 36.97% comparing to the reference model.
摘要-平面设计已经发展并采取了许多形状和形式。大多数布置都是双负荷布置,单元沿走廊面对面布置。另一种类型是两个面向庭院的单负荷公寓。建筑立面也从有阴影的表面到只有最低防晒的表面有所不同。修改设计显然对建筑物的热工性能有影响。研究的目的是调查建筑的外立面结构对建筑热性能的影响。本研究使用仿真软件Design Builder来预测建筑的热工性能。窗区、遮阳区、阳台的几个变体被安排来探索它们对热性能的影响。选择带码的平面作为参考模型。结果表明,与参考模型相比,窗户面积越小,遮阳装置对窗户的覆盖范围越大,与阳台相结合,可以将空气温度降低0.57⁰C,减少36.97%的冷却度小时百分比。

― Climate change that occurs due to urbanization has implications for increased intraurban heating, or usually called urban heat island (UHI). East Surabaya has the most potential to experience increased surface temperature. The urban area has different configuration characteristics and became the most fundamental impact of the phenomenon. However, East Surabaya in climate resilience response has not emphasized adaptation based on urban configuration spatially. While changing the shape of the urban that has been built is most difficult to restore and requires expensive costs. The purpose of this study is to find what’s characteristics urban configuration caused UHI significantly. So, it can be a reference to an adaptation to minimize UHI intensity from the best type of urban configuration. This study uses a positivist paradigm. Remote sensing using LiDAR and Landsat imagery became the main source of this research. With geographic information system (GIS), UHI in the urban and suburban areas of East Surabaya has a temperature difference of around 1,59 0 C. Characteristics of urban configuration are in classifications 2 to 7. Classification 2 is the central area of activity, while classification 7 is a sub-urban area. Urban Configuration have an impact to the UHI intensity. Classification 3 has the biggest effect on UHI.
-由于城市化而发生的气候变化会导致城市内部供暖增加,或通常称为城市热岛(UHI)。东泗水最有可能经历地表温度升高。城市区域具有不同的形态特征,成为影响这一现象最根本的因素。然而,东泗水在应对气候韧性方面并没有强调基于城市空间结构的适应。而改变已经建成的城市的形状是最难恢复的,需要昂贵的成本。本研究的目的是找出哪些特征的城市配置显著影响城市热岛。因此,它可以作为一种参考,以适应从最佳类型的城市配置中最小化UHI强度。本研究采用实证主义范式。利用激光雷达和陆地卫星成像的遥感技术成为本研究的主要来源。根据地理信息系统(GIS),东泗水市区和郊区的城市热岛温差约为1,59°c,城市结构特征为2至7级。第2类是活动的中心区,而第7类是郊区。城市结构对城市热岛强度有影响。3级对城市热岛影响最大。

factory PT Gresik Petrochemicals; it is produced around 1,200,000 tons/year. In order to reduce the amount, an effort needed to use gypsum as fill materials. For this purpose, the problem needs to be considered is that gypsum should not contain substances that harmful to the environment and meet the fill materials requirements. In order to answer all these questions, chemical tests were carried out to determine its heavy metal content. Gypsum plasticity and its particle size distribution were determined by conducting Atterberg limit and sieve analysis tests. Compaction test and CBR test were also carried out to determine the density and its strength. Those results were then analyzed using "The Fifteen Point Method" to obtain a relationship curve between dry density (d) and soakedCBR. This curve was important to determine the soaked-CBR that can be achieved by gypsum materials in the field with different compaction energy 90%, 95%, and 100% of maximum compaction energy. Chemical test result shows that all heavy metals content in gypsum material are far below the regulatory limit; therefore, it is safe for the environment. Besides, Gypsum is non-plastic (NP) material and it is classified as A-4 (AASHTO) or SM (USCS); it means that Gypsum is very good for fill materials and safe to the environment. In addition, the result from the Fifteen Point Method shows that the minimum soaked CBR value is 13% achieved by using 90% of maximum compaction energy with 30-40 % of water content. It means that the gypsum material can be used as selected fill material because it fulfils its requirement where IP<6% and soaked CBR>10%.
工厂PT Gresik石化;年产量约为120万吨。为了减少其数量,需要努力使用石膏作为填充材料。为此,需要考虑的问题是石膏不应含有对环境有害的物质,并满足填充料要求。为了回答所有这些问题,进行了化学测试以确定其重金属含量。通过阿特伯格极限和筛分试验确定了石膏的塑性和粒度分布。并进行了压实试验和CBR试验,以确定其密度和强度。然后使用“十五点法”对这些结果进行分析,以获得干密度(d)与浸渍cbr之间的关系曲线。这条曲线对于确定石膏材料在最大压实能量为90%、95%和100%的情况下在现场所能达到的浸水cbr具有重要意义。化学检测结果表明,石膏材料中所有重金属含量均远低于规定限值;因此,它对环境是安全的。此外,石膏属于非塑性材料(NP),属于A-4 (AASHTO)或SM (USCS);这意味着石膏是非常好的填充材料,对环境是安全的。此外,十五点法的结果表明,在含水量为30- 40%的情况下,使用最大压实能量的90%可获得最小浸渍CBR值为13%。这意味着石膏材料可以作为选择的填充材料,因为它满足IP10%的要求。

Abstrak —Indonesian Ministry of Communication and Informatics reported internet users in Indonesia reached 150 million with a penetration of 56% in January 2019. This indicates the era of information disclosure; therefore, information on government performance is more easily obtained by all levels of society. Society is becoming more sensitive to government performance, and more feedback is being given to the government. This large amount of feedback has stimulated research on public sentiment analysis. This study compares the public sentiment analysis by two different approaches to the government performance of East Java Province. The study was comparing the lexicon-based method approach and the Support Vector Machine (SVM) from the machine learning approach. This study uses Twitter and Instagram datasets, and also the online news media web that reports on East Java. This study found that by using a combined data source of social media and online media, the lexicon-based approach produced an accuracy value of 57.7%; while the SVM machine learning method approach produces an accuracy of 44.7%. without the topics in the document being assessed. The SVM comparison is used because it is a method widely used SA with learning.
摘要-印度尼西亚通信和信息部报告称,2019年1月,印度尼西亚的互联网用户达到1.5亿,渗透率为56%。这标志着信息公开时代的到来;因此,社会各阶层更容易获得政府绩效信息。社会对政府工作表现的关注程度越来越高,政府得到的反馈也越来越多。大量的反馈刺激了公众情绪分析的研究。本研究比较了两种不同方法对东爪哇省政府绩效的民意分析。该研究比较了基于词典的方法和机器学习方法中的支持向量机(SVM)。本研究使用Twitter和Instagram数据集,以及报道东爪哇的在线新闻媒体网络。本研究发现,结合社交媒体和网络媒体的数据源,基于词典的方法的准确率值为57.7%;而SVM机器学习方法的准确率为44.7%。没有评估文件中的主题。使用支持向量机比较是因为它是一种广泛使用的带学习的SA方法。

— Domestic space is where basic human needs are accommodated and understood to the function and its inhabitants. The basic understanding of using domestic space is human activities as a system of activity and areas as a system of settings. However, visual representation techniques in architecture have led to the discriminatory practices towards visually impaired who have limitations on the sense of sight as a primary tool in spatial perception. Thus, studies are necessary to explore the use of domestic space by visually impaired. This paper aims to study the experience of people with visually impaired doing their activities and using a domestic architecture based on the cognition and percetption of their senses. This phenomenological research is studied at the natural setting of domestic housing from the perspective of women with visual impairment who live in Surabaya. The participants are chosen who have actively and independently carried their daily activities in domestic space. The results of this study show women with visual impairment have a specific system of activities and system of settings related to how the senses affect the spatial behavior of visually impaired in accommodating their activities. By doing so, they are able to compromise and create a friendly and accessible domestic environment. their family an accessible Oliver that understanding the experience of disabilities in the environment can explain their problems from the limitations of the social environment as well as the accessibility of the physical environment. Understanding the lived experiences of disabilities requires an in-depth exploration of their daily life experiences, and does not place them as objects of research studies but as participants who are willing to share their experiences which may involve their physiological and psychological feelings. Thus, this study was conducted with visually impaired women as active participants, in the context of dwelling, to see and express the experiences in daily activities and setting based on the cognition of their senses. This study aims to see and formulate
-家庭空间是满足人类基本需求的地方,并理解其功能和居民。对家庭空间利用的基本理解是人类活动作为一个活动系统,区域作为一个设置系统。然而,建筑中的视觉表现技术导致了对视障人士的歧视性做法,视障人士在视觉作为空间感知的主要工具方面受到限制。因此,有必要研究视障人士对家庭空间的使用情况。本文旨在研究视障人士基于其感官的认知和感知进行活动和使用家庭建筑的体验。这项现象学研究是从居住在泗水的视力受损妇女的角度,在家庭住房的自然环境下进行的。参与者是那些在家庭空间中积极独立地进行日常活动的人。本研究结果表明,女性视觉障碍患者有一个特定的活动系统和设置系统,与感官如何影响视觉障碍患者的空间行为以适应他们的活动有关。通过这样做,他们能够妥协并创造一个友好和无障碍的国内环境。他们的家庭是一个无障碍的奥利弗,了解残疾人在环境中的经历可以从社会环境的局限性和物理环境的可及性来解释他们的问题。理解残疾人士的生活经历需要深入探索他们的日常生活经历,而不是把他们作为研究对象,而是作为愿意分享他们的经历的参与者,这些经历可能涉及他们的生理和心理感受。因此,本研究以视障女性为积极参与者,在居住的环境中,基于感官认知,观察和表达日常活动和环境中的体验。本研究旨在观察和制定

—Roads have a very significant role in enhancing various fields as part of the national transport network. Road management includes road construction, improvement, and technical maintenance activities, which are continuously carried out for the physical maintenance of the road. The role of the road service must be fulfilled so as not to compete with the transportation that passes on the road. Based on the phenomena that have been described, we present the analysis of the cost requirements and methods of road handling in addition to the effectiveness of road stability for the next two years. The research was carried out for a case study of the district major road in Gresik Regency, which is represented in this situation by three main roads. The analysis of a data set is based on the variables of historical data. Then, we analyze using time series with moving averages, exponential smoothing, and trend projection. Next, the method for setting a maintaining strategy of overcoming prediction and its relation to the solidity of the roads, using fuzzy tahani. The results analyzed are confirmed by the recommended output for the next two years. research. In this study, we will try to prepare all the data and also project the data into a prediction that can be useful.
