The Kedang Pahu river is one of the tributaries of the Mahakam river. The research plan is located in Damai District, West Kutai Regency, East Kalimantan province. Recently, the Damai District and Damai Seberang areas have flooded activities that have caused the surrounding settlements to flood into residential areas and block existing road access. Planning analysis and knowing the annual flood elevation is essential. The analysis uses the method of calculating the mean annual flood (MAF) to search for the average annual flood discharge data and the search for the average annual elevation. Data validation using a simple linear regression method produces a correlation coefficient of 58.67%, or R-value = 0.5867. The analysis results in the value of Q1 or the 1st year period, the mean annual flood rate of the average annual flood discharge is 2576.0695 m³/second and the value associated with the magnifying factor (GF) is the average annual flood discharge rate of Q5=3014,00 m³/ sec, Q10 = 3529.22 m³/sec, Q20 = 4095.95 m/sec, Q50 = 5049.10 m³/sec, Q100 = 5847.68 m³/sec, Q200 = 6852.34 m³/sec, Q500 = 8423.75 m³/sec & Q1000 = 9917.87 m³/sec. The analysis results at HEC-RAS 5.07 based on manning analysis showed the elevation values were Q1=18.47m, Q5=18.85m, Q10=18.86m, Q20=19.18m, Q50=19.74m & Q100=19.99m. Researchers only show elevations up to Q100 or the 100th year because of limited data and the reviewed data accuracy.

Electric power theft is a serious concern in the world irrespective of being major revenue losses and developing a nation. More than one-third part of the electricity generated power is lost due to electric theft, power loss, and inefficiencies in the distribution system. Interdicted or illegal utilization of electricity has not only affected economically but also obstructs the design and modeling phases of the power system. Due to electric theft, providing wrong data input values for power system analysis and difficult to load forecasting. In this paper, an inventive Simulink model is designed to detect and monitoring of electric power theft in power system distribution networks through Power Line Communication (PLC). Electric power theft was detected with variance amendment in the amplitude of carrier signal with a narrow band. PLC technique is utilized for data communication over the power line. A narrow band power line carrier signal which has high frequency transferred in power line alongside with power frequency signal. The deviation in the amplitude of the transmitted carrier signal is monitored at the regular time- intervals and the stealing of electricity can be distinguished by the computing of distinction change within the amplitude of the carrier signal. In a normal case, the signal present fixes pattern and waveform, but in the case of power theft, the signal shows some variation and disturbance in a within waveform pattern. A pattern recognition and monitoring approach is used for direct power theft in the PLC model. The Simulink model is performed on MATLAB software to analyze the performance and efficient results that satisfy the proposed Simulink model.
电力盗窃是世界上一个严重的问题，无论它是主要的收入损失还是发展中国家。超过三分之一的发电量由于电力盗窃、电力损失和配电系统效率低下而损失。禁止或非法用电不仅影响经济效益，而且阻碍了电力系统的设计和建模阶段。由于盗电，为电力系统分析提供错误的数据输入值，给负荷预测带来困难。本文设计了一种新颖的Simulink模型，通过电力线通信(power Line Communication, PLC)对配电网中的窃电行为进行检测和监控。采用窄带载波信号幅度方差修正的方法检测窃电。电力线上的数据通信采用PLC技术。一种窄带电力线载波信号，其高频与工频信号一起在电力线中传输。在规定的时间间隔内监测传输载波信号的幅值偏差，通过计算载波信号幅值内的差值变化来识别窃电。在正常情况下，信号呈现固定的模式和波形，但在窃电情况下，信号在波形模式内显示出一些变化和干扰。在PLC模型中采用了模式识别和监控方法来实现直接窃电。在MATLAB软件上对Simulink模型进行了仿真，分析了满足Simulink模型的性能和效率。

Pangururan Subdistrict in Samosir Regency requires rearranging its open land functions related to the meaning of the environment. From the civil engineering perspective, landslides can occur suddenly during the rainy season without being noticed by the people around the Pangururan sub-district, Samosir Regency. To realize this program, the community can add the function of the drainage channel into a mobile fish pond around the Pangururan Subdistrict, Samosir Regency, which still has a large area of land/settlements to become a running fish pond drainage channel. This can increase residents' income which is beneficial for the community around the drainage canal. In addition, the problem of overflowing water in the rainy season will be minimized. To implement this program, an analysis should be prepared in advance to evaluate the drainage channel that will function as a fish pond around Pangururan District, Samosir Regency. In line with the government's program in promoting and increasing the income of residents, the existing drainage channels should be utilized. Unproductive drainage channels can become productive drainage channels by cultivating freshwater fish along the drainage channel while simultaneously irrigating rice fields. Therefore, a wet section of the plan is made along 1000 meters where the condition of the drainage channel is planned according to the analysis. The depth of the drainage channel for running water fish ponds is 100 to 170 cm and the width of the top side from 100 cm to 150 cm, and the width of the sides below 100 cm. Based on the calculations, the first process that must be done is to first calculate the maximum planned rainfall, calculate the planned discharge, calculate the dimensions of the channel, and flood discharge (designated discharge), where QT = 0.278 x C x I x A = 6.69 m3/s at a speed of plan average flow. The flow velocity of the drainage channel is installed with a sluice so that the average velocity value is = 1/n R2/3 x S1/2 = 3.8 m/s, the cross-sectional area of a fish pond with a wet cross-section A = a x b = 1.904 m2, the cross-sectional area of the wet plan making fish ponds where the channel design discharge for fish ponds is QS = AS x V = 7.23 m3/s and the calculation of sluice gates with a width of 50 cm and a height of 170 cm for fish pond water with Q = (u x b x a ) x 3 of 10.8 m/s.
Samosir摄政区的Pangururan街道需要根据环境的意义重新安排其开放土地的功能。从土木工程的角度来看，滑坡可能会在雨季突然发生，而不会被Pangururan街道周围的人注意到，Samosir Regency。为了实现这一计划，社区可以在Samosir摄政区Pangururan街道周围增加排水渠的功能，使其成为一个流动的鱼塘排水渠，该街道仍然有大片的土地/定居点。这可以增加居民的收入，这对排水渠周围的社区是有益的。此外，雨季溢水的问题将被最小化。为了实施这一计划，应事先准备一份分析报告，以评估将在萨莫西尔摄政区庞古鲁兰区周围用作鱼塘的排水渠。根据政府促进和增加居民收入的计划，应该利用现有的排水渠道。通过沿排水渠养殖淡水鱼，同时灌溉稻田，使非生产性排水渠成为生产性排水渠。因此，根据分析，沿1000米规划排水通道条件的湿段。活水鱼塘排水通道深度为100 ~ 170厘米，上侧宽度为100 ~ 150厘米，100厘米以下两侧宽度为100厘米。根据计算，首先要做的是首先计算最大计划降雨量，计算计划流量，计算渠道尺寸，洪水流量(指定流量)，其中QT = 0.278 x C x I x A = 6.69 m3/s，流速为计划平均流量。排水通道的流速是安装闸,平均速度值= 1 / n R2/3 x S1/2 = 3.8 m / s,鱼池的横截面积与湿截面x = a b = 1.904平方米,湿计划使鱼塘的横截面积,鱼塘的通道设计流量Q = x V = 7.23立方米/秒,计算闸门的宽50厘米,高170厘米鱼池水与Q = (u x b) x 3 10.8 m / s。

Physical intervention in a market area tends to change user habits in responding to the space. This situation can ruin the authenticity of the sense of place and the loss of local identity for generations. This study aims to reveal the authenticity and understanding of the Inpres Market, a traditional market in Lhokseumawe. Re-development has been carried out at the Inpres Market to improve the layout of the stalls, change the architectural form of the building with a contemporary image, and increase the floor of the building vertically into two levels. Apprehensively this physical intervention will erode the meaning of place that has been attached to people's memories for a long time. This study must be conducted before any other new physical intervention occurs for any renovation or revitalization reason. This study is place-based research by choosing Inpres Market in Lhokseumawe as the case study. The research variable uses physical (tangible) and social (intangible) variables to reveal the sense of place in the market.

The climate crisis caused by global greenhouse gas emissions has led to many disasters around the world in recent years. Some of these disasters are floods in various parts of Europe, melting of Arctic glaciers, and rising water levels in the oceans. People living on islands in Southeast Asian countries are forced to migrate due to rising water levels. With the increase in the frequency of such situations, life on earth is at risk. Greenhouse gas emissions harm not only humans but also animals and plants. The most effective measure that can be taken against this is to stay away from fossil fuels. With the use of fossil fuels, the carbon ratio in the atmosphere increases, and climatic imbalances occur. For this reason, the interest in alternative energy sources is increasing. Wind energy is one of the most widely used renewable energy sources. This is due to the low cost of installation and ease of use. The most important factor affecting the aerodynamic efficiency of wind turbines is the blade profiles. Numerous types of wing profiles have been designed and put into use. In this study, numerical analyzes of NACA 0015 and NACA 4415 airfoils at various angles of attack were performed by determining forces every five degrees between 0 and 20 degrees using ANSYS Fluent commercial software. Lift coefficients and drag coefficients were also calculated for the angles of attack used. According to the analysis results obtained, optimum attack angles were found for each airfoil. As a result, NACA0015 and NACA4415 airfoils were compared in terms of their performance.

PT. Ika Bina Agro Wisesa (IBAS) is a company that produces products in the form of crude oil or CPO (Crude Palm Oil). The company sets a minimum production target of FFB that must be processed to reach 30 tons in one boiling with a minimum production target of 600 tons/day. The company is required to increase productivity. The problem so far is that the company has never measured the productivity of the production process, which will then affect the achievement of production targets. Measurement of productivity is critical because the measursizeoductivity can determine whether the company meets productivity targets for production or not. Therefore, it is necessary to measure productivity to assess the value of productivity and efforts to increase productivity in CPO production and how to increase productivity in CPO production and efforts to increase productivity using the Objective Matrix (OMAX) method at PT. Ika Bina Agro Wisesa. Analysis of productivity using the OMAX method, ratio 3 (labor productivity) and ratio 4 (machine productivity) has a very high percentage of poor performance, which means that ratio and 4 have an insufficient level of productivity. Unlike the case with the achievement of productivity ratio 1 (productivity of raw materials) and ratio 2 (productivity of working hours) wh, ich shows a low percentage of poor performance, which means that the productivity level of ratio one and ratio 2 has a better productivity level than ratio three and ratio 4 Analysis The results of the productivity index in the company decreased and increased for each month, in November it experienced a decrease of -79.49, while in December it experienced a significant increase in the amount of 595.02 and January at 69.98. in February decreased to -23.63. Furthermore, productivity in March - September 2021 was unstable, with an increase and dropped for July, a decrease of -0.64 and, a slight increase in August of 0.28.
PT. Ika Bina Agro Wisesa()是一家以原油或CPO(粗棕榈油)形式生产产品的公司。公司设定的最低生产目标是一次煮沸必须加工的FFB达到30吨，最低生产目标为600吨/天。公司被要求提高生产率。到目前为止的问题是，该公司从未测量生产过程的生产率，这将影响生产目标的实现。生产力的测量是至关重要的，因为测量生产力可以决定公司是否达到生产的生产力目标。因此，有必要衡量生产力，以评估生产力的价值和努力提高CPO生产的生产力，以及如何提高CPO生产的生产力和努力提高生产力在PT. Ika Bina Agro Wisesa使用目标矩阵(OMAX)方法。使用OMAX方法分析生产率，比率3(劳动生产率)和比率4(机器生产率)表现不佳的百分比非常高，这意味着比率和4的生产率水平不足。与实现生产率比1(原材料生产率)和生产率比2(工作时间生产率)的情况不同，表现不佳的比率较低，这意味着比率1和比率2的生产率水平比比率3和比率4的生产率水平更好。分析该公司的生产率指数结果逐月呈下降趋势，11月份下降了-79.49。12月为595.02点，1月为69.98点。2月份降至-23.63。此外，2021年3月至9月的生产率不稳定，7月的生产率有所下降，下降了-0.64,8月略有上升，为0.28。
{"title":"Increasing Productivity in CPO Production Using The Objective Matrix Method","authors":"Defi Irwansyah, C. I. Erliana, Fadlisyah Fadlisyah, Mutammimul Ula, Mahlil Fahrozi","doi":"10.52088/ijesty.v2i2.232","DOIUrl":"https://doi.org/10.52088/ijesty.v2i2.232","url":null,"abstract":"PT. Ika Bina Agro Wisesa (IBAS) is a company that produces products in the form of crude oil or CPO (Crude Palm Oil). The company sets a minimum production target of FFB that must be processed to reach 30 tons in one boiling with a minimum production target of 600 tons/day. The company is required to increase productivity. The problem so far is that the company has never measured the productivity of the production process, which will then affect the achievement of production targets. Measurement of productivity is critical because the measursizeoductivity can determine whether the company meets productivity targets for production or not. Therefore, it is necessary to measure productivity to assess the value of productivity and efforts to increase productivity in CPO production and how to increase productivity in CPO production and efforts to increase productivity using the Objective Matrix (OMAX) method at PT. Ika Bina Agro Wisesa. Analysis of productivity using the OMAX method, ratio 3 (labor productivity) and ratio 4 (machine productivity) has a very high percentage of poor performance, which means that ratio and 4 have an insufficient level of productivity. Unlike the case with the achievement of productivity ratio 1 (productivity of raw materials) and ratio 2 (productivity of working hours) wh, ich shows a low percentage of poor performance, which means that the productivity level of ratio one and ratio 2 has a better productivity level than ratio three and ratio 4 Analysis The results of the productivity index in the company decreased and increased for each month, in November it experienced a decrease of -79.49, while in December it experienced a significant increase in the amount of 595.02 and January at 69.98. in February decreased to -23.63. Furthermore, productivity in March - September 2021 was unstable, with an increase and dropped for July, a decrease of -0.64 and, a slight increase in August of 0.28.","PeriodicalId":14149,"journal":{"name":"International Journal of Engineering, Science and Information Technology","volume":"352 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76407685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CV. Raja Hati is a company that is engaged in the process of refinishing tires that have been bald into new ones. The tire retreading process has a relatively high percentage of defects, such as 14.8% Printing Process, 12.3% Surface Leveling, 8.6% Tire Curing, and so on. The problems in this study are the factors that cause defects in terms of human aspects, the types of errors that most often occur in the production process, and the value of human error probability (HEP) in the production process at CV. Raja Hati. This study aims to determine the factors that cause defects in terms of human aspects, the types of errors that most often occur in the production process and the value of human error probability (HEP) in the production process. The research was conducted using the SHERPA and HEART methods. The SHERPA method’s study results show that the types of errors that often occur in the tire retreading process are many wrong operator actions. Still, on the proper object (A7), the operator is wrong in dividing the time in doing work (A2), and the operator is not suitable for doing his job (A5). This study concludes that the factors that cause product defects in the tire retreading process are the absence of a procedure for correcting errors by 21.63%, the need for different techniques in doing work to facilitate operators by 27.04%, inexperienced operators by 12.36%, and inexperience and independent inspection has a percentage of 12.36%. The results of the calculation of the HEP value show that the average HEP value in the tire retreading process is 0.8552 or 85.52%, while the operator reliability value is 14.48%.
