Abstract

Activities in a company or institution are something that is usually done, the forms of these activities are generally training, socialization of new regulations, inauguration, and so on. These activities need to be recorded and the data managed as documentation or reference and consideration in subsequent activities. This activity requires planning starting from preparation, scheduling, distributing invitations via email, to implementing and recording the attendance of invited participants. The case study was conducted at PT Pelni Indonesia as an Indonesian National Shipping company that often carries out internal activities within the company. The problem that occurs in the management of company activities at PT Pelni is that so far it is still using the manual system. The participant registration process, participant data collection, sending invitations, recording participant attendance and so on are carried out in handwriting and stored in an excel file. Of course, this makes it difficult to search and manage data, and allows data loss or document slippage to occur. One solution that can be used to overcome these problems is to build an information system for managing company activity data. The management system can assist the HRD for data management needed in the implementation of activities carried out by the company. QR Code technology is also used to encrypt participant invitation numbers, verify participant data and to record attendance. The result of developing this system is a data management system for company activities by utilizing Quick Response Code (QR Code) technology. The generated QR Code can store various participant data in only 1 code and is used to verify participant data.

Abstract

Feature extraction techniques are applied to obtain features that will be useful in classifying and recognizing images. Feature extraction techniques are very helpful in various image processing applications. Many studies show the effectiveness of feature extraction before classification. There is also research showing that a feature extraction method may be good for certain classification approaches but may also be preferable. The impact of the sample and its size can also determine the results of the application of feature extraction techniques in the classification process. In this study, the author aims to prove the effectiveness of the application of the HOG feature extraction technique on the classification with the SVM method on flower images. The experiment was carried out on two groups of images, where the first group was image classes with relatively uniform colors and shapes, both in shape and color. and the second group is image classes with relatively different colors and shapes in the same class. The results showed that image datasets with relatively uniform colors and shapes do not require the application of any feature extraction to produce high accuracy. For classification by performing feature extraction in this study it gives different results for the two interest groups.

Abstract

Saat ini penyiraman tanaman secara tradisional dirasa kurang efisien karena lamanya dalam penyiraman. Tak hanya itu, penyiraman secara tradisional juga membutuhkan banyak tenaga dalam melakukan aktifitas tersebut. Hal ini menyebabkan pemilik tidak bisa meninggalkan tanaman mereka dalam waktu yang lama, karena tanaman dapat kekurangan air dan kehilangan nutrisi. Teknik penyiraman yang ada pada WIBEY Farm masih belum memakai penyiraman secara rutin dan terjadwal secara otomatis. Berdasarkan latar belakang ini maka rumusan masalah yang didapat adalah, bagaimana merancang sistem penjadwalan penyiraman tanaman aeroponik secara otomatis. Penelitian ini bertujuan untuk dapat merancang suatu sistem penyiraman otomatis dan memberikan fasilitas berupa alat guna mempersingkat waktu.Penyiraman dengan metode penjadwalan berbasis arduino merupakan teknologi maju dalam bidang irigasi mikro yang bekerja secara efisien guna meningkatkan produksi serta mutu dari hasil pertanian/perkebunan. Dengan menggunakan mikrokontroler arduino uno yang telah diprogram untuk melakukan penjadwalan penyiraman otomatis melalui modul RTC DS1307 dapat melakukan penyiraman sesuai dengan jadwal yang kita inginkan serta kita dapat memonitoring dengan LCD Keypad Shield untuk melihat proses penyiraman berjalan selama 1 menit. Dengan pengujian yang telah didapatkan dengan bantuan alat sesnsor suhu dan kelembaban didapatkan bahwa Nozzle Sprinkler juga dapat memelihara kesuburan tanaman karena setelah dilakukannya penyiraman, suhu menjadi menurun. Hal ini dikarenakan Nozzle Sprinkler dapat mengubah cairan menjadi butiran. Adanya alat ini membuat WIBEY Farm dapat mempersingkat waktu untuk melakukan penyiraman serta memudahkan memelihara kesuburan tanaman dalam budidaya tanaman aeroponik.
