Introducing alternatives material on cement-based material manufacturing is the need for environmental sustainability due to the excessive mining of sand from quarry and river bed. At the same time, industrialization headed to an uncontrollable growth of waste. This fact encourages the researcher to enhance the utilization of recycled waste in construction practice. On one side, it affords a solution for waste management, and on the other hand, it contributes to an eco-friendly construction material that minimizes the environmental impact. This paper aims to investigate the usability of the iron waste obtained from the wrought iron industry, as natural fine aggregates replacement. In particular, it focused on studying the physical characteristic of waste aggregates and the effect of partial replacement of natural sand on mortar strength. Mortar cube specimen made with various levels of replacement (0%, 10%, 20% and 30 %) and also various cement-aggregates volumetric proportion, which are 1:3, 1:4, 1:5, 1:6, and 1:7. All of the measurement parameters are taken consecutively based on ASTM norms. The current work remarks that both waste aggregates and natural aggregates reveal complete fulfillment in the aggregate requirement of ASTM standard. Furthermore, the mortar cube test confirmed that the mortar passes the strength grade for N class and O class, which suitable for the above-grade and non-load bearing application.
由于过度开采采石场和河床的沙子,在水泥基材料制造中引入替代材料是环境可持续性的需要。与此同时,工业化导致了垃圾的不可控制的增长。这一事实促使研究者在建筑实践中加强对再生垃圾的利用。一方面,它为废物管理提供了解决方案,另一方面,它有助于减少对环境影响的环保建筑材料。本文旨在探讨熟铁工业废铁作为天然细骨料替代品的可用性。重点研究了废骨料的物理特性以及部分替代天然砂对砂浆强度的影响。采用不同置换水平(0%、10%、20%、30%)和不同水泥骨料体积比(1:3、1:4、1:5、1:6、1:7)制成砂浆立方体试件。所有测量参数均按ASTM标准连续测量。目前的研究表明,废骨料和天然骨料都完全符合ASTM标准的骨料要求。砂浆立方体试验证实该砂浆通过了N级和O级强度等级,适用于等级以上和非承重应用。

Corrosion is one of the processes of metal damage or degradation due to redox reactions between a metal and various substances in its environment that produce undesirable compounds. In the water one of the environmental parameters is water resistivity. By knowing the connection between water resistivity and corrosion rate, it is possible to monitor laboratory tests with water environments that have different levels of corrosiveness. Therefore, it is necessary to conduct an analysis to determine the effect of water resistivity on water corrosivity, understand the factors that influence the corrosion rate and calculate the corrosion rate of the irrigation gate steel plate on the water environment. This analysis uses a laboratory scale, analysis with talagasari irrigation water media, domestic wastewater, PDAM water and dead river estuary water. All water media used have a high level of corrosiveness. The factor that causes the low resistivity value is the large amount of inorganic minerals containing metal in the water so that at low resistivity values the corrosion rate increases. In the results of this laboratory analysis, it is proven that the more acidic the water medium, the faster the corrosion rate and the more alkaline the water medium, the slower the corrosion rate.
腐蚀是由于金属与其环境中的各种物质发生氧化还原反应而产生不良化合物而导致金属损坏或降解的过程之一。在水中,其中一个环境参数是水电阻率。通过了解水的电阻率和腐蚀速率之间的联系,就有可能监测具有不同程度腐蚀的水环境的实验室测试。因此,有必要进行分析,确定水电阻率对水腐蚀性的影响,了解影响腐蚀速率的因素,计算灌溉闸门钢板对水环境的腐蚀速率。本分析采用实验室比例尺,用塔拉斯灌溉水介质、生活污水、PDAM水和死河河口水进行分析。所有使用的水介质都具有高度的腐蚀性。造成低电阻率值的因素是水中含有大量含金属的无机矿物,所以在低电阻率值时,腐蚀速度加快。在本次实验室分析的结果中,证明了酸性越强的水介质腐蚀速度越快,碱性越强的水介质腐蚀速度越慢。

The massive use of natural materials in major road infrastructure frequently disrupts the sustainability of the ecosystem in the environment. A solution for using other materials is needed to minimize the impact of using these natural materials. GBFS (Granulated Blast Furnace Slag) is waste from blast furnace combustion of iron and steel material in granular form, which characteristically can be used as a substitute for medium aggregate asphalt mixture material. The study was conducted by several testing, such as GBFS material testing, AC-WC asphalt mixture characteristic test using Absolute Density Method, and performance testing on AC-WC asphalt mixtures, based on its structural performance and dunctional performance with the percentage of GBFS as medium aggregate variation at 0%, 50%, 75%, and 100%. The study results show that the utilization of the percentage of GBFS as a medium aggregate substitution by 75% improves functional performance and structural performance of AC-WC asphalt mixture.Keyword: GBFS, Asphalt Mixture, AC-WC, Medium Aggregate.

In this pandemic era, doors in public places are one of the objects that can be an intermediary for the transmissionof the Covid-19 virus. That's why various kinds of developments in the field of technology are designed to provide an alternative in avoiding the transmission of the Covid-19 virus through doors in public places.The purpose of this study is to design an Arduino Uno-based automatic door simulator using Proteus software. The sensor used in this system is a PIR (Passive Infra Red) sensor. The way the system works is that when the PIR sensor detects someone's movement, the Data OUT Pin will be HIGH. Because this pin is connected to the Arduino, it will detect this HIGH Signal and detect that someone is approaching the door and will provide input to the DC motor, then the DC motor will move to the right or left to pull the door. From the simulation results, the delay between sensor readings and the movement of the DC motor is about 3 to 5 seconds.
在这个大流行时代,公共场所的门是可能成为Covid-19病毒传播媒介的物体之一。这就是为什么技术领域的各种发展旨在提供一种替代方案,以避免新冠病毒通过公共场所的门传播。本研究的目的是利用Proteus软件设计一个基于Arduino的自动门模拟器。该系统中使用的传感器是PIR(无源红外)传感器。该系统的工作方式是,当PIR传感器检测到某人的运动时,Data OUT引脚将为HIGH。因为这个引脚连接到Arduino,它将检测到这个HIGH信号,并检测到有人正在接近门,并将向直流电机提供输入,然后直流电机将向右或向左移动以拉门。从仿真结果来看,传感器读数与直流电机运动之间的延迟约为3 ~ 5秒。

BUMDes Rancang jaya has been observing and studying other BUMDes that have succeeded in developing tourist villages and attracting tourists. They see the motivation of tourists in visiting Sinarancang Village because of its location near Setu Patok with beautiful views. This is one of the reasons why tourism needs to be developed for developing villages as a means of capturing new opportunities in meeting community needs. The purpose of this study is to identify entrepreneurial characteristics that are applied in business development carried out by BUMDes and to describe the concept of BUMDes leadership which has entrepreneurial characteristics in realizing the development strategy of the Sinarancang tourism village. This study used a qualitative descriptive method with secondary data analysis in the form of village policy documents and primary data analysis from observations and interviews. Regional leadership needs to demonstrate entrepreneurial characteristics. In this case, the leadership of BUMDes Rancang Jaya has shown the beginnings of entrepreneurial characteristics according to Schumpeter (1934) and Kirzner (1973), namely believing in change and making innovations in institutional settings. To realize the development strategy of the Sinarancang Tourism Village, it requires BUMDes leadership with entrepreneurial insight, namely those that fulfill 6 entrepreneurial characteristics in the context of regional development (Stimson, 2009), so that the motivation of entrepreneurship in the context of regional development is realized, namely creating individual economic benefits that occur from cultural enhancement or the regional economic context (business climate) and social welfare as well as community benefits stemming from spillover and institutional effects.Keywords: Sinarancang, Tourism Village, BUMDes, Regional Leadership, Entrepreneurship
Sinarancang村作为seu Patok地区具有自然旅游和开放公共空间的潜力。Sinarancang村有一个战略位置,因为它靠近Setu Patok。自然和河流旅游的潜力以及社区砂浆住宅产业是激励BUMDes Rancang Jaya将其开发为旅游村的一些吸引力。BUMDes Rancang Jaya是Sinarancang村新成立的公司,它的愿景是创建一个名为Sinarancang的旅游村,能够吸引锡雷邦的游客来参观。BUMDes Rancang jaya一直在观察和研究其他成功开发旅游村并吸引游客的BUMDes。他们看到了游客参观Sinarancang村的动机,因为它靠近seu Patok,风景优美。这就是为什么需要发展旅游业来发展村庄,作为抓住满足社区需求的新机会的手段之一。本研究的目的是识别BUMDes在商业发展中应用的创业特征,并描述BUMDes在实现Sinarancang旅游村发展战略中具有创业特征的领导概念。本研究采用定性描述方法,以村政策文件的形式进行二次数据分析,并从观察和访谈中进行一手数据分析。区域领导需要展现企业家特征。在这种情况下,BUMDes Rancang Jaya的领导表现出熊彼特(Schumpeter, 1934)和柯兹纳(Kirzner, 1973)认为的企业家特征的开端,即在制度设置中相信变化和创新。要实现Sinarancang旅游村的发展战略,需要BUMDes具有创业洞察力的领导,即满足区域发展背景下的6个创业特征的领导(Stimson, 2009),从而实现区域发展背景下的创业激励。即创造文化提升或区域经济环境(商业环境)和社会福利带来的个人经济利益,以及溢出效应和制度效应带来的社区利益。关键词:Sinarancang,旅游村,BUMDes,区域领导,企业家精神

Cultural tourism offers culture in the form of tourist objects that are tangible or concrete, intangible or abstract, as well as those that are living culture and cultural heritage. The potential of the Jalawastu Area has unique cultural values such as traditional ceremonial events and traditions that are still being maintained. This study aims to see the Jalawastu Area as a cultural tourism destination in Brebes Regency. The research method used is a descriptive method that aims to describe or describe phenomena or relationships between the phenomena being studied systematically, factually, and accurately (Kusmayadi, 2000). In addition, the descriptive method is a way of analyzing comprehensive data in the framework of explaining the conditions or characteristics of an area that occur as a particular consideration according to Densin. Based on the results of the analysis, the conclusion is that the development of the tourism heritage area of the Jalawastu Cultural Village has great potential as a cultural tourism destination, and the aspect of the analysis and culture that is owned by the existence of the Jalawastu Cultural Village has a unique architecture encourages the creation of a unique and distinctive domestic image. If the Jalawastu Cultural Village is developed with good management and planning, it will encourage the formation of a tourism heritage area with the main attraction being a tourist attraction for traditional ceremonies and traditional arts as historical and cultural tourism. The research recommendations include: on the product side, improving quality in the packaging of cultural and artificial products in the tourism heritage of the Jalawastu Cultural Village in an attractive tour package, adding supporting activities such as the tangible and tangible potential of Brebes Regency in the tourism area of the Jalawastu Cultural Village as a symbol To introduce the Brebes area as a whole to domestic and foreign tourists, the program is to innovate for the heritage tourism attractions of the Jalawastu Cultural Village to make it more attractive.
文化旅游以有形的或具体的、无形的或抽象的旅游对象以及活的文化和文化遗产的形式提供文化。Jalawastu地区的潜力具有独特的文化价值,例如仍在保留的传统仪式活动和传统。本研究旨在将Jalawastu地区作为布里布摄政的文化旅游目的地。所使用的研究方法是一种描述性方法,旨在系统地、真实地、准确地描述或描述所研究的现象或现象之间的关系(Kusmayadi, 2000)。此外,描述性方法是在解释一个区域的条件或特征的框架中分析综合数据的一种方法,根据Densin作为一个特定的考虑而发生。根据分析结果,得出的结论是贾拉瓦斯图文化村旅游遗产区域的开发具有巨大的文化旅游目的地潜力,并且贾拉瓦斯图文化村的存在所拥有的文化方面具有独特的建筑风格,鼓励了独特而鲜明的国内形象的塑造。如果在良好的管理和规划下开发Jalawastu文化村,它将鼓励形成一个以传统仪式和传统艺术为主要景点的旅游遗产区,作为历史文化旅游。研究建议包括:在产品方面,在Jalawastu文化村旅游遗产中提高文化和人工产品的包装质量,在一个有吸引力的旅游套餐中,增加配套活动,如在Jalawastu文化村旅游区的有形和有形潜力,作为象征,向国内外游客介绍布雷布地区作为一个整体;该项目旨在对贾拉瓦图文化村的遗产旅游景点进行创新,使其更具吸引力。

The rain that fell in the city of Cirebon, especially the drainage on Jalan Pemuda, could not accommodate and drain the water so that it could create puddles on the roads and surrounding areas. Hourly rain intensity, planned flow rate and channel cross-sectional dimensions are the first steps for flood prevention. Hydrological analysis is used to calculate the discharge capacity of the drainage plan. The results were then analyzed the dimensions of the channel, the drainage ability to accommodate the falling rainwater where Qs is bigger than Qp. the channel discharge has not been able to accommodate the Q plan in the channel so that there will be a runoff of 17.759%. So to anticipate runoff, it is necessary to have a channel improvement plan of 33.477%. In addition to channel improvement solutions, arrange and define the boundaries of water storage areas by measuring and mapping boundaries and issuing regulations that prohibit or limit the construction of buildings that can reduce the ability of areas to store and absorb rainwater by referring to the basic building coefficient (KDB) permitted as stated in the RT/RW.
西雷本市的雨水,特别是贾兰佩姆达的排水系统,无法容纳和排水,因此可能在道路和周围地区造成水坑。每小时降雨强度、计划流量和河道断面尺寸是防洪的第一步。利用水文分析方法,计算了排水方案的泄流量。然后分析了通道的尺寸,以及Qs大于Qp时的排水能力。河道流量已不能适应河道中的Q计划,因此将有17.759%的径流。因此,要预测径流,必须有33.477%的渠道改善计划。除了渠道改善解决方案外,通过测量和绘制边界来安排和定义储水区域的边界,并根据RT/RW中允许的基本建筑系数(KDB)颁布法规,禁止或限制建造可能降低区域储存和吸收雨水能力的建筑物。
