Abstract

One of data grouping process method is k-harmonic clustering method (KHM) which has a relatively short and simple process. However, it has a weakness at cluster center point. Randomly formed cluster center point causes difficulty to converge solutions. One way to solve the problem at the cluster center point requires a method which has a global solution for KHM. The method is Improved artificial bee colony (IABC), improvement of artificial bee colony (ABC) method based on behavior patterns of honey bee colony in food searching process. Advantage of the IABC method is able to have more optimum global solution. This research proposes a new method of clustering using improved artificial bee colony and K-Harmonic means (IABC-KHM) to optimize the center point in clusters that lead to global solution. In this study, the IABC is functioned for finding the most optimum cluster center point for the data clustering process using KHM. Furthermore, the performance test of the IABC-KHM clustering method is compared with ABC and ABC-KHM methods on three different datasets. The result of mean value of best function of IABC-KHM method of Iris dataset is 152,87, Contraceptive Method Choice dataset is 918,54, and Wine dataset is 31,01. Moreover, the result of the average value of the best F-Measure method IABC-KHM Iris dataset is 0.90, the Contraceptive Method Choice dataset is 0.41, the Wine dataset is 0.95. To conclude, IABC-KHM method has successfully optimized the position of cluster center point that directs the cluster result which has global solution.

Abstract

Farming using hydroponic systems has emerged as an effective alternative to address the problem of limited agricultural land. However, hydroponic farming requires strict maintenance and control. In light of these challenges, the development of monitoring technology is necessary to assist in monitoring and controlling hydroponic systems. The development of a monitoring system is carried out to address the challenges of maintenance and control in hydroponic farming through the development of effective and accurate monitoring technology, thus enhancing the overall productivity and success of hydroponic plant cultivation. This study aims to develop a monitoring system using Arduino Mega 2560, Wemos D1 R2, E201 sensor, DHT22 sensor, HC-SR04 sensor, and BH1750 sensor. In this research, the fuzzy logic method was applied to generate outputs for the water pump actuator, pH up pump, and pH down pump. The HC-SR04 and E201 sensor data served as fuzzy inputs, while the Arduino Mega 2560 functioned as the fuzzy data processor, and the Wemos D1 R2 was responsible for sending data to the server via the internet. The data successfully stored in the server's database would be displayed on the monitoring dashboard. The HC-SR04 sensor testing results showed an average %error of 0% and an accuracy of 100%. The E201 sensor exhibited an average %error of 0.07% and an accuracy of 99.33%. The DHT22 sensor had an average %error of 0.05% and an accuracy of 99.49% for temperature data, while for humidity data, it had an average %error of 2.58% and an accuracy of 75.23%. The BH1750 sensor had an average %error of 0.13% and an accuracy of 99.66%.

Abstract

Sistem penggajian umumnya merupakan proses penggajian dari awal sampai gaji itu dibayarkan sesuai dengan hak masing-masing karyawan dapat dilakukan atau dilaksanakan dengan sistematis dan diharapkan tidak akan terdapat kesalahan dalam prosedur penggajian. Pada PT. Bumi Sawindo Permai (BSP) sebagai perusahaan pengolahan kelapa sawit yang menjadi tempat penelitian memiliki 3 unit bisnis yang ditunjang oleh pemanfaatan teknologi informasi, meliputi: perangkat lunak Enterprise Resource Planning ASCEND, dan Standart Operational Procedure (SOP) ASCEND, serta SOP Sistem Menejemen Integrasi (SMI). Proses bisnis produksi dan operasional tidak didefinisikan pada semua komponen tersebut. BSP memberlakukan sistem penggajian secara sistematis sesuai dengan prosedur yang berlaku, akan tetapi prosedur ini tidak tercantum dengan jelas kedalam sebuah blueprint. Ditemukan ketidakselarasan dari ketiga komponen tersebut pada implementasinya. Hal ini mereduksi indeks kinerja perusahaan khususnya pada proses penggajian karyawan yang dilakukan oleh bagian Human Capital Management (HCM) di 3 unit bisnis BSP. Dengan demikian perlu dilakukan eliminasi bottleneck pada proses bisnis berjalan. Pemodelan proses bisnis dengan Business Process Modelling Notation (BPMN) dilakukan sebagai langkah strategis pengembangan SOP sebagai standar baku mutu untuk peningkatan efisiensi perusahaan dalam hal pengelolaan sistem pembayaran gaji karyawan yang lebih terukur.
