Abstract

Internet of things (IoT) application needs to be evaluated to gain better improvement and innovation. The evaluation can be examined from user acceptance. The unified theory of acceptance and use of technology (UTAUT) can be used as a model to identify user acceptance in using technology, including IoT application. However, the ease of use of technology must be included, so the determining of easy of use from negative aspects must be included, so the 5th hypothesis of UTAUT (hindering condition) must be included. Before this hypothesis is formulated and included in evaluation by the user, obtaining data to identify the real condition of the user is performed using forensic analysis and ACO based classification. To evaluate this activity, this 5th hypothesis is measured by reliability and validity test, also hypothesis testing itself.

Abstract

Pembekalan keterampilan pada anak-anak asuh di Panti Asuhan merupakan sebuah hal penting yang dapat mereka gunakan sebagai bekal di masa depan. Panti Asuhan Putri Aisyiyah Malang memberikan para anak asuhnya dengan keterampilan berwirausaha melalui usaha katering bernama PAP’A. Seiring berkembangnya usaha katering PAP’A tersebut, jangkauan pelanggan yang melakukan pemesanan juga semakin bertambah, sehingga diperlukan adanya manajemen pemesanan yang baik. Sayangnya, katering PAP’A tidak memanfaatkan teknologi untuk melakukan manajemen pemesanan yang dilakukan oleh pelanggan. Mereka hanya mencatat transaksi pemesanan yang dilakukan melalui telepon, WhatsApp, atau SMS ke dalam sebuah buku. Hal inilah yang menyebabkan seringnya terjadi human error dan berimbas pada kerugian di pihak pelanggan maupun pihak katering PAP’A. Oleh karena itu, pada kegiatan pengabdian kepada masyarakat ini, diusulkan sebuah sistem informasi dalam bentuk website yang dikembangkan untuk memudahkan pihak katering PAP’A dalam melakukan manajemen pemesenan. Dengan adanya sistem informasi ini, pihak katering PAP'A dapat melakukan pengelolaan daftar pesanan, daftar produk makanan, dan pembayaran secara lebih terstruktur. Adanya fitur pembayaran juga memberikan kemudahan bagi pihak katering PAP'A untuk menghasilkan nota bukti pembayaran yang dilakukan oleh pelanggan.

Abstract

The pandemic has caused almost all educational institutions to use online learning media to support learning activities. E-learning is a technology that is widely used because it can accommodate all learning activities. However, in general, e-learning can only perform automatic assessments for multiple choice answers but not for essay answers, so that manual assessment by the teacher becomes difficult and takes a long time. In this study, the winnowing algorithm was applied to the automatic assessment process on students' essay answers by measuring their similarity to the teacher's answer key. The stages in the automatic assessment using the winnowing algorithm begin with forming a series of k-grams, calculating the hash value, forming a window from the hash value, calculating the fingerprint value, and calculating the Jaccard Coefficient to obtain the percentage of text similarity results. The test results show that the winnowing algorithm can provide good performance when the answers to questions are in the form of short entries with the number of hashes not smaller than the window value. Meanwhile, on questions with long answers, the winnowing algorithm can still work well with an average difference of 5.2% from the results of the assessment carried out by the teacher.

Abstract

Wisma Gaharu as one of the plantations assisted by the Malang Regency Perhutani Service conducts an agarwood nursery with the species Gyrinops Versteegii. However, the agarwood plants cultivated at Wisma Gaharu are attacked by caterpillars annually, causing damage to the agarwood leaves. Accordingly, the growth of agarwood plants is hampered, and further dry out and die. This causes the owner of Wisma Gaharu to suffer huge losses, especially if the pest attacks the plant which is ready for the inoculation process in the dry season. To overcome this, agarwood farmers must pay high attention and vigilance to fight agarwood caterpillar attacks that occur throughout the year since it is considered the most dangerous pest for plants. The unavailability of production support equipment is one of the problems faced by Wisma Gaharu; there is also a need for work safety training (K3) regarding proper supporting equipment use considering the risks faced by workers in the agriculture sector. The above problems underline the main reasons for supporting equipment procurement and administering work safety training.
