It is estimated that 175 million people in Indonesia utilize the Internet, according to the most recent We Are Social survey. 160 million of them are internet users who utilize social media, according to this data. It is estimated that 19.5 million Indonesians use Twitter. This is consistent with the numerous tweets that users have posted on Twitter about a variety of topics, including politics, music, health, and education. The death penalty is still one of the most popular subjects that is addressed on Twitter. When a judge rules that someone will be executed as retribution for a crime they have committed, this is referred to as the death penalty. As a result, sentiment analysis utilizing the Support Vector Machine technique with linear kernel features and Python programming was used to study public opinions on the death sentence. To improve the accuracy of the results obtained, data labeling on 848 data that were received through the scraping process was done manually in this study. Positive data is categorized as belonging to the class that supports the death sentence, while negative data is categorized as belonging to the class that opposes it. The study that was done shows an 8:2 difference between the training and test data. After preprocessing a dataset containing 758 data points, of which 606 will be utilized for training and 152 for testing, we obtain 91% accuracy, 91% precision, 100% recall, and 95% f1-score
根据最新的 "我们是社会"(We Are Social)调查,印度尼西亚估计有 1.75 亿人使用互联网。根据这一数据,其中 1.6 亿人是使用社交媒体的互联网用户。据估计,有 1950 万印尼人使用 Twitter。这与用户在 Twitter 上发布的关于政治、音乐、健康和教育等各种话题的大量推文相吻合。死刑仍然是 Twitter 上最热门的话题之一。当法官裁定某人将因所犯罪行而被执行死刑时,这就是所谓的死刑。因此,我们利用带有线性内核特征的支持向量机技术和 Python 编程进行了情感分析,以研究公众对死刑的看法。为了提高所获结果的准确性,本研究对通过搜刮过程获得的 848 条数据进行了人工数据标注。积极的数据被归类为属于支持死刑的类别,而消极的数据被归类为属于反对死刑的类别。研究显示,训练数据和测试数据的差异为 8:2。在对包含 758 个数据点(其中 606 个用于训练,152 个用于测试)的数据集进行预处理后,我们获得了 91% 的准确率、91% 的精确率、100% 的召回率和 95% 的 f1 分数。

In the Indonesian archipelago, boats play a major role in people's daily mobility. In the realm of transportation, especially on sea vessels, it is crucial to keep an eye on the circumstances and state of affairs when traveling long distances. The objective of this study is to use an optocoupler sensor based on the Internet of Things (IoT) and a real-time monitoring technique to track the speed of an electric boat. This instrument can be tested using three different treatments: low-level gas, medium-level gas, and high-level gas with five repetitions. Motor speed was measured at 938 Rpm with a Knot difference of 0.7 utilizing XSpeed and an optocoupler sensor for low-speed measurements. Using an optocoupler sensor and XSpeed, the medium speed tests yielded a motor speed of 1205.6 Rpm and a Knot difference of 1.7. Using an optocoupler sensor and XSpeed, high-speed measurements yielded a motor speed of 1985.4 Rpm and a Knot difference of 1.2. Because the Blynk application may display data of both boat speed and motor rotational speed, readings obtained from the optocoupler sensor yield higher accuracy than those obtained from the comparison application XSpeed
在印度尼西亚群岛,船只在人们的日常出行中扮演着重要角色。在交通领域,尤其是在海船上,长途旅行时对环境和状态的关注至关重要。本研究的目的是利用基于物联网(IoT)的光耦合器传感器和实时监测技术来跟踪电动船的速度。该仪器可使用三种不同的处理方法进行测试:低浓度气体、中浓度气体和高浓度气体,重复五次。利用 XSpeed 和光耦合器传感器进行低速测量时,电机转速为 938 Rpm,节差为 0.7。使用光耦合器传感器和 XSpeed,中速测试的电机速度为 1205.6 Rpm,节差为 1.7。使用光耦合器传感器和 XSpeed 进行高速测量时,电机转速为 1985.4 Rpm,节差为 1.2。由于 Blynk 应用程序可同时显示船速和电机转速数据,因此从光耦合器传感器获得的读数比从对比应用程序 XSpeed 获得的读数精度更高。

One of the most important aspects of preventing illegal usage of firearms is safe storage. An inventive way to guarantee that only authorized owners can access the firearms is to incorporate fingerprint technology into the design of electric firearm storage systems. The use of fingerprint technology to increase the security of gun storage is desperately needed. However, issues with the finger's health, such as stains, cuts, and dampness, can impair the accuracy of the detection. This study employs a quantitative methodology using five fingerprint detection situations to test the accuracy of the system. The Arduino ESP was used as the foundation for the system implementation throughout the nine months that the research was conducted at the Kodiklatad Poltekad Electronics Laboratory. According to the test results, the system has 100% accuracy in identifying five different fingerprint detecting scenarios. But limitations are implied by the system's incapacity to identify damp, damaged, or dusty fingertips. Consequently, further thought must be given to these circumstances in order to improve system reliability. The design of an electric gun storage unit using Arduino ESP-based fingerprint technology has the potential to increase the security of gun storage, but more work is needed to address some issues that limit detection accuracy
防止非法使用枪支的最重要方面之一是安全存储。要保证只有经过授权的枪支所有者才能使用枪支,一种别出心裁的方法就是在电动枪支存储系统的设计中采用指纹技术。使用指纹技术来提高枪支储存的安全性是非常必要的。然而,手指的健康问题,如污渍、割伤和潮湿,会影响检测的准确性。本研究采用定量方法,使用五种指纹检测情况来测试系统的准确性。在 Kodiklatad Poltekad 电子实验室进行研究的九个月中,系统的实施以 Arduino ESP 为基础。根据测试结果,该系统在识别五种不同的指纹检测场景时准确率达到 100%。但是,该系统无法识别潮湿、损坏或沾有灰尘的指尖,这就意味着存在局限性。因此,必须进一步考虑这些情况,以提高系统的可靠性。使用基于 Arduino ESP 的指纹技术设计的电动枪支储存装置有可能提高枪支储存的安全性,但还需要做更多的工作来解决限制检测准确性的一些问题

The employment of security features is crucial to the operation of many modern electronic gadgets in the current 5.0 era as time and technology advance. This means that we must keep coming up with new ideas and producing instruments that will enhance security. Among the many issues that come up is the fact that guns are still registered, checked out, and returned using public books, which leaves space for data tampering or the chance that the books are lost. The primary goal of this research is to create and execute a web-based system that uses fingerprints to monitor the borrowing and return of firearms. Because of its nature online-his, this system will streamline operations and enable users to conveniently view inventory from any location. Researchers employ literature methodology, which includes reading, debating, synthesizing, and developing the concepts employed, in addition to employing laboratory techniques and the necessary tools to accomplish their objectives. The web server on which the security monitoring system for keeping firearms is based has undergone extensive testing and analysis, and the findings indicate that generally, the device can operate as intended. This conclusion is based on traffic analysis and access patterns on the web server. Following the completion of five tests with a 95% accuracy rate. Finally, the security monitoring system for the storage of firearms is based on a web server and has undergone extensive testing and analysis with a 90% speed and accuracy rate; the findings indicate that, on the whole, the instrument can perform as intended

If businesses wish to compete in the industrial world, they must produce quality and process results. No matter how big or little, some goods will always fail to generate or be rejected in a production process. In this case, companies in the automobile sector have noticed an increase in the number of pinholes that have been returned during the past three months. The company established a maximum reject rate of 0.9% each month based on the rejected data; from May to July, the average reject rate was 0.23%. Finding the factors causing the surge in pinhole rejects that occurred between May and July is the aim of this investigation. The analysis showed that the increase in pinhole rejects was caused by a variety of variables, including machine, process, and human factors. Further examination disclosed alterations to the device's configuration and software, along with the operator's persistent incapacity to comprehend the process. As operations become less efficient, repair components build up in the manufacturing line area. As a result, an improvement plan is needed, which is put into action by giving operator training and rearranging the machine and its software according to process requirements. Operators with a greater understanding of the process yield better results and higher productivity. As a result, operator confidence will rise along with performance. It was discovered that after developments in the field of human resource development, the number of rejections had dropped. Before the repair was finished, the average reject from May to July 2023 was 0.23%; following the repair, the average reject from August to October 2023 was 0.09%
企业要想在工业世界中竞争,就必须在生产过程中保证质量和效果。无论大小,在生产过程中总会有一些货物无法生成或被拒收。在这种情况下,汽车行业的公司注意到,在过去的三个月里,被退回的针孔数量有所增加。该公司根据废品数据确定每月最高废品率为 0.9%;从 5 月到 7 月,平均废品率为 0.23%。本次调查的目的是找出导致 5 月至 7 月间针孔废品激增的因素。分析表明,针孔废品增加是由多种变量造成的,包括机器、流程和人为因素。进一步检查发现,设备的配置和软件发生了改变,而且操作员一直无法理解操作过程。随着操作效率的降低,维修部件在生产线区域内不断堆积。因此,需要制定一项改进计划,通过对操作员进行培训,并根据工艺要求重新安排机器及其软件,将改进计划付诸实施。操作员对工艺有了更深入的了解,就能获得更好的结果和更高的生产率。因此,操作员的自信心也会随之提高。我们发现,在人力资源开发领域取得进展后,废品数量有所下降。维修前,2023 年 5 月至 7 月的平均废品率为 0.23%;维修后,2023 年 8 月至 10 月的平均废品率为 0.09%。

Industry 4.0's pervasive digital ideas have completely changed how businesses operate. A lot of big businesses have switched to digital systems. However, due to a lack of funding and digital infrastructure, SME sector digitalization issues still exist. Inventory management is one of the many manual methods that many SMEs still have to rely on, which makes it prone to error. To manage inventories more accurately and effectively, manual systems must be changed. The goal of this project is to improve inventory management efficiency by creating a dependable and affordable automated system. A cloud database is connected to the system to provide quick inventory monitoring on warehouse shelves. Prototyping and statistical testing are used in the study technique to evaluate the system's dependability. Using an Internet of Things-based single-board computer, the research creates an inventory monitoring system. With a daily implementation cost of IDR 642.92, the system is deemed cost-effective based on inventory monitoring results on warehouse shelves. Because the system's performance reached a Cronbach's alpha value greater than 0.8, the inventory management system used in the study is regarded as dependable for application in real-world systems to increase inventory management accuracy

A dynamic state of people, processes, environments, goods, and services that either meet or beyond expectations is known as service quality. It is vital to improve services to compete and provide higher-quality services at the Muara Satu Community Health Center through initiatives to enhance human resources and ongoing performance improvement. The Muara Satu Community Health Center has received major accreditation for its services; however, as of yet, no reassessment has been conducted. The management of Puskesmas wishes to refine the accreditation to become plenary so that patient satisfaction can serve as a gauge of the success of the center's health services provided to the community. This study aims to evaluate the degree of agreement between patient interests and satisfaction and the Muara Satu Community Health Center's service quality performance. Additionally, it seeks to identify the attributes that should be given priority for service improvement through the application of the Potential Gain in Customer Value (PGCV) method. Patients' complaints regarding services, such as uncomfortable waiting rooms and a lack of information about the ailments they were suffering from, posed a challenge for this study. Five categories were created based on 17 characteristics of the patient requests made at the health center and were given to 58 pre-selected samples. This category includes Assurance, Empathy, Tangible, Reliability, and Responsive. The Muara Satu Health Center is required to implement seven priority orders for quality improvement based on the IPA and PGCV methods, based on data processing findings. These orders include requiring the Community Health Center staff to inform patients before providing services, having a comfortable waiting area, and having officers act quickly and appropriately when necessary. Facilities in Puskesmas are fully equipped. The types of ailments, their treatments, and how to take medication are all thoroughly explained by the doctor. Furthermore, physicians allot enough time for patient examinations
服务质量是指人员、流程、环境、商品和服务达到或超出预期的动态状态。通过加强人力资源和持续改进绩效的措施来提高服务质量,对于穆阿拉苏图社区医疗中心的竞争和提供更高质量的服务至关重要。Muara Satu 社区医疗中心的服务已获得主要认证,但至今尚未进行重新评估。Puskesmas 管理层希望将认证细化为全体认证,以便将患者满意度作为衡量该中心为社区提供的医疗服务是否成功的标准。本研究旨在评估患者利益和满意度与 Muara Satu 社区医疗中心服务质量表现之间的一致程度。此外,本研究还试图通过应用客户价值潜在收益(PGCV)方法,确定在改善服务时应优先考虑的属性。患者对服务的投诉,如候诊室不舒适、缺乏有关疾病的信息等,为本研究带来了挑战。根据患者在医疗中心提出的要求的 17 个特征,创建了五个类别,并对 58 个预选样本进行了分类。这些类别包括保证、同情、有形、可靠和响应。根据数据处理结果,Muara Satu 健康中心必须按照 IPA 和 PGCV 方法执行七项优先质量改进指令。这些指令包括要求社区医疗中心的工作人员在提供服务前告知患者、提供舒适的候诊区,以及在必要时让工作人员迅速、适当地采取行动。Puskesmas 的设施设备齐全。医生会详细解释疾病的类型、治疗方法和服药方法。此外,医生会为病人检查留出足够的时间。

Effect of the number of blades in palm oil chopping machine 棕榈油切碎机刀片数量的影响
Pub Date : 2024-07-31 DOI: 10.37373/tekno.v11i2.955

A single hectare of oil palms may yield 10 tons of fronds annually, with young oil palms producing 40–56 fronds and mature oil palms producing 40–48 fronds. One kind of solid debris that comes from making palm oil is called palm oil fronds. A method is required to lessen palm frond waste because substantial volumes of it will still need to degrade. Waste palm fronds are reduced in size and broken down more quickly with the assistance of a chopping machine. But for slicing palm frond trash, the frond machines that are now in use are not the best. The purpose of this study is to ascertain whether adding more blades to a chopping machine's cutting knife can enhance the chopping process. Two designs with 19 and 26 blades were manufactured and tested for the research, and the results were compared with the cutting knife design from the prior study, which had 24 blades. According to the test results, adding additional blades to the cutting knife will improve the machine's effective capacity by 14.22% and decrease the size of waste palm fronds and leaves, allowing the machine to operate more efficiently. In addition, reducing the size of palm fronds with more knives can make them easier to break down
一公顷油棕榈树每年可产 10 吨叶片,幼龄油棕榈树可产 40-56 片叶片,成熟油棕榈树可产 40-48 片叶片。棕榈油生产过程中产生的一种固体碎屑被称为棕榈油叶。由于大量的棕榈叶仍需要降解,因此需要一种方法来减少棕榈叶废物。在切碎机的帮助下,废弃的棕榈叶可以更快地缩小和分解。但对于切碎棕榈叶垃圾来说,目前使用的切叶机并不是最好的。本研究的目的是确定在切碎机的切刀上增加刀片是否能增强切碎过程。为进行这项研究,我们制造并测试了 19 片刀片和 26 片刀片的两种设计,并将测试结果与之前研究中 24 片刀片的切削刀设计进行了比较。测试结果表明,在切割刀上增加刀片可将机器的有效产能提高 14.22%,并减小废弃棕榈叶和棕榈叶的体积,使机器的运行效率更高。此外,通过增加刀片来缩小棕榈叶的尺寸,可以使其更容易破碎
