Bondan Hamlet is a hamlet in Kampung Laut District, Cilacap. One of the community's problems is the lack of clean water and the PLN electricity network. In 2020, a desalination facility named Sidesi Mas will be built in Bondan Hamlet with a capacity of 240 liters/hour and using the reverse osmosis principle. The energy source for desalination uses a solar power plant (PLTS). Desalination management requires economic analysis, especially in determining the selling price of desalinated water. The cost of producing desalinated water can be calculated using the Cost of energy (CoE) value of the PLTS or the costs incurred to produce electrical energy per 1 kWh. To get the PLTS CoE, this article discusses a simulation to analyze the performance of PLTS desalination systems with Homer software. Homer performs analytical calculations based on a location input, solar energy potential, capacity, and costs of PLTS components as well as electrical load data. The simulation results show that PLTS energy production is 535 kWh/year, the CoE value is IDR 21,975/kWh and the production cost for producing clean water is IDR 183.13/liter.
邦丹哈姆雷特(Bondan Hamlet)是西拉普Kampung Laut区的一个小村庄。社区的问题之一是缺乏清洁的水和印尼国家电力公司的电力网络。2020年,将在邦丹哈姆雷特建造一座名为Sidesi Mas的海水淡化设施,其容量为240升/小时,并采用反渗透原理。海水淡化的能源使用太阳能发电厂(PLTS)。脱盐管理需要进行经济分析,特别是在确定脱盐水的销售价格时。生产脱盐水的成本可以使用PLTS的能量成本(CoE)值或每1kWh生产电能所产生的成本来计算。为了获得PLTS CoE,本文讨论了用Homer软件模拟分析PLTS脱盐系统的性能。Homer根据位置输入、太阳能潜力、PLTS组件的容量和成本以及电力负载数据进行分析计算。模拟结果表明,PLTS的发电量为535 kWh/年,CoE值为21975/kWh印尼盾,生产清洁水的生产成本为183.13印尼盾/升。

The increase in greenhouse gases in the form of CO2 gas as vehicle exhaust emissions contributes to climate change. Technological approaches and alternative fuels continue to reduce fuel consumption, but this is not enough. Another method is to use eco-drive behavior, one of which is related to replacing the air filter. This study is purposed to provide guidelines for motorized vehicles operating in selected areas in Lampung Province in the behavior of eco-driving. The results of the fuel consumption test using the full-to-full method found that at each filter distance (8,000 km, 12000, and 16,000 km), vehicles operating in Mesuji with the highest deficiency, followed by Tanjung Bintang and Krui areas. In line with eco-drive behavior, for vehicles operating in Mesuji, the air filter replacement period must be faster than the other two areas, followed by Tanjung Bintang and Krui.
作为汽车尾气排放的二氧化碳形式的温室气体的增加导致了气候变化。技术方法和替代燃料继续减少燃料消耗,但这还不够。另一种方法是使用环保驾驶行为,其中一种方法与更换空气滤清器有关。本研究旨在为在楠榜省选定地区运营的机动车提供生态驾驶行为指南。使用完全到完全方法进行的油耗测试结果发现,在每个滤清器距离(8000公里、12000公里和16000公里),在Mesuji运行的车辆的燃油不足量最高,其次是Tanjung Bintang和Krui地区。根据环保驾驶行为,对于在Mesuji运营的车辆,空气滤清器更换期必须比其他两个地区快,其次是Tanjung Bintang和Krui。

Assets are resources owned by an entity. Cilacap State Polytechnic is a higher education institution that has many assets. Current asset maintenance and repair services are still carried out conventionally. Each work unit must fill out a maintenance and repair proposal form and then submit it to the Maintenance, Repair, and Maintenance Unit (UP3). The proposal will be recorded and scheduled to be followed up by the Technician. The problem that occurs is that the proposal form is often scattered and even lost so the response time is often slow. In addition, maintenance and repair schedules are often not ordered according to the time of the request. This has an impact on the abandonment of work in certain work units. The purpose of this research is to create an information system for the repair and maintenance of campus assets. In order for maintenance and repair services to be carried out according to the time of the request, the FCFS method is applied. Thus, the service process for maintaining and repairing campus assets becomes more organized, schedules (queues) are sequenced, and the response time for incident handling is faster.
资产是实体所拥有的资源。奇拉卡普州立理工学院是一所高等教育机构,拥有许多资产。目前的资产维护和维修服务仍按常规进行。每个工作单位必须填写维护和维修建议表,然后提交给维护,维修和维护单元(UP3)。该建议将被记录并安排由技术员跟进。出现的问题是,提案表单经常是分散的,甚至丢失,因此响应时间通常很慢。此外,维护和维修时间表往往不是按照要求的时间排序的。这对某些工作单位的放弃工作产生了影响。本研究的目的是建立一个校园资产维修与维护的信息系统。为了按照要求的时间进行维护和维修服务,应用了FCFS方法。因此,维护和修复校园资产的服务流程变得更加有组织,调度(队列)排序,事件处理的响应时间更快。

Freshwater fish is a type of fish that is very popular with the wider community. The problem that often occurs in cultivators is the timing of feeding fish. This study introduces automatic pellet sowing with a DC motor as a pellet ejector. The method used is by identifying research variables. This research was conducted with 3 variations of DC motor rpm rotation with 2 different pellet sizes. The data obtained showed that the farthest ejection distance is 3 mm pellets with a rotational speed of 6000 rpm, while the closest ejection distance is 3 mm pellets with a rotational speed of 1000 rpm, and it is also concluded that the data findings are the estimated time to run out of 3 kg of pellets for each pellet sample with three variations of DC motor rotational speed. Pellets with the fastest time of 1.90 s are pellets with a size of 3 mm with a rotational speed of 6000 rpm, while the longest time is 5.2 s, namely pellets with a size of 1 mm with a rotational speed of 1000 rpm.

The OSIS chairman is the highest leader in the OSIS management structure and is accompanied by a vice-chairman. Therefore, a selection with several criteria is needed to determine the best candidate. Things that are considered in this selection are realism, maturity, organizational experience, public speaking, discipline, character, organizational activity, and responsibility. By utilizing a decision support system, the best candidates are obtained for the candidate for chairman and vice-chairman of the student council. This system is made with the method used to assist the selection process, namely, profile matching. Profile matching is used to find the profile of a job that is sought from a predetermined specification. This method provides a solution and has a clear objective in decision-making. On the other hand, the method used to develop a decision support system is the incremental method. The selection of the incremental method is based on the fact that this method has an iterative nature, which can adapt to the many repetitions that occur during the development process. The novelty of this research is the recommendations generated from the developed decision support system. There are notifications about the results of decisions to users, in this case, the candidates for the OSIS chairman and vice chairman who are alternatives in the election process. This study resulted in recommendations in the form of candidates for OSIS chairman and vice chairman by the candidate's profile.
OSIS主席是OSIS管理结构中的最高领导人,由副主席陪同。因此,需要根据几个标准进行选择,以确定最佳候选人。在这个选择中考虑的事情是现实主义,成熟度,组织经验,公开演讲,纪律,性格,组织活动和责任。利用决策支持系统,选出学生会主席和副主席的最佳人选。该系统是用辅助选择过程的方法,即轮廓匹配来制作的。配置文件匹配用于从预定的规范中查找作业的配置文件。该方法提供了一种解决方案,决策目标明确。另一方面,用于开发决策支持系统的方法是增量法。增量方法的选择是基于这样一个事实,即该方法具有迭代的性质,它可以适应开发过程中发生的许多重复。本研究的新颖之处在于从已开发的决策支持系统中产生的建议。有关于决策结果的通知给用户,在这种情况下,是选举过程中的备选方案OSIS主席和副主席的候选人。这项研究的结果是,根据候选人的个人资料,以主席和副主席候选人的形式提出建议。

Solar panels such as PLTS can be an alternative to complete electricity needs. However, the intensity and temperature of the sun that can not be adjusted are an obstacle to the use of solar panels. Continuous absorption of sunlight can cause solar panels to overheat. Therefore, it is necessary to cool the solar panels, therefore the heat absorbed does not exceed the capacity. Phase Change Material (PCM) paraffin graphite is one of the coolants for solar panels. PCM paraffin graphite was used to coat solar panels and then measured for voltage, current, and temperature. The results were compared with solar panels that were not covered with PCM paraffin graphite. The test results found that solar panels coated with PCM produced a lower surface temperature of 0.1458% than those without PCM. Meanwhile, the efficiency and power produced by PCM-coated solar panels were 19.496% and 0.02685% higher than solar panels without PCM, respectively, so the use of PCM paraffin graphite in solar panels can increase their efficiency.
PLTS等太阳能电池板可以作为满足电力需求的替代方案。然而,无法调节的太阳强度和温度是太阳能电池板使用的障碍。持续吸收阳光会导致太阳能板过热。因此,有必要冷却太阳能电池板,因此吸收的热量不超过容量。相变材料石蜡石墨(PCM)是太阳能电池板的冷却剂之一。用PCM石蜡石墨涂覆太阳能电池板,然后测量电压、电流和温度。结果与未覆盖PCM石蜡石墨的太阳能电池板进行了比较。测试结果发现,涂覆PCM的太阳能电池板表面温度比未涂覆PCM的太阳能电池板低0.1458%。与未涂覆PCM的太阳能电池板相比,涂覆PCM的太阳能电池板效率和发电量分别提高了19.496%和0.02685%,因此在太阳能电池板中使用PCM石蜡石墨可以提高太阳能电池板的效率。

Many methods can be used by the community to burn coconut shells into charcoal, one of which is by utilizing appropriate technology fueled by diesel oil, namely shell powder processing machines. The production of briquettes from coconut shells is still limited and has not developed rapidly because the process of shelling coconut shells is still simple thus it takes three to five days. The use of adhesive amounts is not optimal. This is done to fulfill the community's desire; therefore, coconut shell waste can be managed as raw material for making briquettes to become a source of community income. The purpose of this research is to optimize the production of coconut shell briquettes by utilizing appropriate technology fueled by diesel oil. The method used is by conducting a trial process of starch adhesive treatment, namely 1%, 2%, 3%, 4%, 5%, 6%, 6.25%, and 7% with the amount of water 900 ml at a temperature of 70 0C to form gelatinization. As a result, it was found that the best starch adhesive treatment is in the 6.25% test with the ratio of the starch adhesive mixture, shell powder, and water being 0.25: 4: 0.9. It indicates that the resulting briquette shape is more efficient, has high density and small briquette pores.
社区可以使用许多方法将椰子壳烧成木炭,其中一种方法是利用以柴油为燃料的适当技术,即壳粉加工机。由于椰子壳脱壳的过程仍然简单,需要三到五天的时间,因此从椰子壳中生产压块仍然有限,并且没有迅速发展。胶粘剂用量不理想。这样做是为了满足社区的愿望;因此,椰子壳废料可以作为制造压块的原料加以管理,成为社区收入的来源。本研究的目的是利用适当的柴油为燃料,优化椰子壳型煤的生产工艺。所采用的方法是在70℃的温度下,分别用1%、2%、3%、4%、5%、6%、6.25%、7%的水加入900 ml,进行淀粉胶粘剂处理的试验过程,形成糊化。结果表明,淀粉黏合剂与壳粉、水的配比为0.25:4:9 9时,黏合剂配比为6.25%。结果表明,该型煤形状效率高,密度大,孔隙小。

A more quantifiable perspective is assuming the role of mechanistic management in an effort to enhance business based on its capacity to transform data into knowledge and insight. The industry has not completely supported its business strategy also with driven data. Using a transaction dataset taken from one of the Kaggle.com challenges, this experiment attempts to determine consumer spending patterns and Retail Fashion business revenues (H&M Personalized Fashion Recommendations). The results of the experiment are the number of transactions based on customer age, the most sales product and one-time purchased item, and the type of product that generates the highest and smallest income. The approach employed is EDA using the Python language. In order for businesses to generate analytical findings that provide future perspectives and to help identify the gap by delivering analytical results in the form of suggestions that can be perpetuated, the findings of this experiment are intended to support the capabilities of simulation. The challenge in this experiment is the abundance of datasets, which necessitates a suitable operating environment.
一个更可量化的视角是承担机械化管理的角色,努力基于将数据转化为知识和洞察力的能力来增强业务。该行业还没有完全支持其商业战略,也没有用数据驱动。本实验使用Kaggle.com挑战中的一个交易数据集,试图确定消费者支出模式和零售时尚业务收入(H&M个性化时尚推荐)。实验的结果是基于客户年龄的交易次数、销售最多的产品和一次性购买的物品,以及产生最高和最小收入的产品类型。所采用的方法是使用Python语言的EDA。为了让企业产生分析结果,提供未来的视角,并通过以建议的形式提供分析结果来帮助识别差距,本实验的结果旨在支持模拟的能力。这个实验的挑战是数据集的丰富性,这需要一个合适的操作环境。
