Implementasi Neural Network dalam Mengendalikan Input dan Output pada Penyiraman dan Pemupukan Tanaman Otomatis Berbasis IoT
Get PDFAgriculture is an important sector in human life. However, in practice, agriculture still faces many challenges such as difficulties in optimally controlling watering and fertilizing crops. To overcome this problem, an automatic plant watering and fertilizing system was developed as an alternative solution. This system can help farmers control watering and fertilizing plants automatically and optimally based on soil and plant conditions measured by sensors. In practice, automation systems for watering and fertilizing plants usually still use simple rules based on the experience or theory of farmers. Therefore, the implementation of a neural network in an automated system of watering and fertilizing plants can help predict irrigation needs for plants accurately and control watering and fertilizing automatically. To prove the effectiveness of the proposed method, testing was carried out using the Neuroph Studio application. From the test results, the total error results for the tool in controlling the output are less than 0.01 of the desired output value. These results are good and indicate that the neural network is an effective method of choice as a learning parameter. In addition, by using IoT technology, the automation system can be connected to the internet, so that it can be accessed remotely and monitored in real-time. This makes it easier for users to control the automation system and monitor the state of the plants

Analisis Usability pada Human Capital Management System PT. XYZ menggunakan WEBUSE Model
Get PDFHuman Capital Management System (HCMS) has become a necessity for organizations to perform administrative personnel services. PT XYZ started implementing HCMS in 2019 as an online self-service for personnel administration, which was previously done manually. During this transition phase, not all employees understand how to use the HCMS system due to its confusing interface. As a result, many employees still prefer assistance from the HR/IT team to make changes to their data rather than doing it themselves. This research was conducted to analyze the usability of the HCMS system using the WEBUSE method. There are four categories used: Content, Organization, and Readability (COR); Navigation and Links (NAL); User Interface Design (UID); and Performance and Effectiveness (PAE). Each category serves as a basis for measuring usability. Data was collected through questionnaires and interviews with respondents to obtain values and levels of WEBUSE usability based on user satisfaction aspects In the case study of this research, it was obtained from the results of the questionnaire distributed as many as 13 respondents stated that in general, the usability of the HCMS system was at the Good level. This research provides recommendations for improving the self-service HCMS based on the needs or experiences of employees using the system. Also contributes to the scientific study of UI/UX and provides an ideal overview practitioner in developing an HCMS system

Profesionalisme Dan Independensi Auditor Terhadap Kinerja Auditor
Get PDFAt this time, public trust in the public accounting profession began to diminish, this was due to the many cases of accounting manipulation. A Public accounting firm (KAP) is a public accounting organization that obtains a license in accordance with laws and regulations that operates in the field of providing professional services in public accounting practice. The auditor profession has been in the public spotlight in recent years. An auditor must have high professionalism in carrying out his duties. The audit results of an auditor must be accountable to interested parties. The auditor\u27s performance is the result of the auditor\u27s work in carrying out the assignment of examining the financial statements of an entity with the aim of determining the fairness of the financial statements. The quality of financial reports is centered on the auditor\u27s performance. To achieve good performance, an auditor must have an attitude of independence. This study aims to determine how independence and professionalism affect auditor performance. The results of this analysis indicate that auditor professionalism and auditor independence have a positive effect on auditor performance. Based on these results, it can be concluded that an auditor who conducts audits in a professional manner will act independently so that the audit results cannot be influenced by other parties.

Analisis Pengaruh Co-Firing Biomassa Terhadap Kinerja Peralatan Boiler PLTU Batubara Unit 1 PT. XYZ
Get PDFA biomass co-firing program has been put in place at power plants by PLN to support policies relating to the renewable energy mix. The extent to which continuous biomass co-firing at various generating load conditions will affect the performance of boiler equipment is unknown. The goal of this study is to ascertain the effects of ongoing biomass co-firing on the efficiency of boiler equipment under various generating load scenarios. An observational approach as well as interviewing techniques were used to collect the data. By hand, using Microsoft Excel software, the calculation value for a specific fuel consumption and net plant heat rate is found. The operating parameters of the boiler equipment performance are then compared with benchmark or commissioning data. The performance of boiler equipment (medium speed mill, boiler fan, air preheater) is unaffected by the co-firing process, and all of its parameters remain within acceptable bounds. As can be seen from the Mmdium speed mill motor and boiler fan flows, which decreased but not significantly, the performance of boiler equipment during the co-firing process is lighter. There is a decrease in boiler furnace temperature despite changes in load, and boiler equipment performance is still within limits. The average total production cost dropped from 485.324 Rp/Kwh to 484.585 Rp/Kwh with co-firing. During the course of the study, the average Net Plant Heat Rate during the co-firing process fell from 2862.85 kcal/kwh to 2866.35 kcal/kwh.Program co-firing biomassa telah diterapkan di pembangkit listrik oleh PLN untuk mendukung kebijakan yang berkaitan dengan bauran energi terbarukan. Sejauh mana co-firing biomassa terus menerus pada berbagai kondisi beban pembangkit akan mempengaruhi kinerja peralatan boiler tidak diketahui. Tujuan dari penelitian ini adalah untuk memastikan efek dari co-firing biomassa yang sedang berlangsung pada efisiensi peralatan boiler di berbagai skenario beban pembangkit. Pendekatan observasi serta teknik wawancara digunakan untuk mengumpulkan data. Dngan menggunakan perangkat lunak Microsoft Excel secara manual, diharapkan dapat memperoleh nilai perhitungan untuk konsumsi bahan bakar spesifik dan laju panas bersih pembangkit, dimana parameter operasi kinerja peralatan boiler dibandingkan dengan data benchmark atau commissioning. Dari penelitian dihasilkan bahwa performa peralatan boiler (medium speed mill, kipas boiler, air preheater) tidak terpengaruh oleh proses co-firing, dan semua parameternya tetap berada dalam batas yang dapat diterima. Diperoleh juga bahwa aliran motor medium speed mill dan fan boiler yang menurun tidak signifikan dan kinerja peralatan boiler pada saat proses co-firing ternyata menjadi lebih ringan. Dilain sisi terdapat penurunan suhu tungku boiler beserta terjadinya perubahan beban, namun kinerja peralatan boiler masih dalam batas. Rata-rata total biaya produksi turun dari 485.324 Rp/Kwh menjadi 484.585 Rp/Kwh dengan co-firing. Selama penelitian berlangsung, rata-rata net Plant Heat Rate selama proses co-firing turun dari 2862,85 kcal/kwh menjadi 2866,35 kcal/kwh
