Abstract

Kenyataan menunjukkan bahwa tidak sedikit jumlah guru yang kandas dalam mengurus kenaikan pangkat/golongan mereka. Penyebabnya adalah keterbatasan keterampilan dan pengalaman guru dalam menulis serta publikasi karya ilmiah. Karena itu, dipandang perlu dilakukannya sosialisasi untuk membekali pemahaman guru-guru di Kecamatan Amanuban Tengah tentang penulisan dan publikasi karya ilmiah. Kegiatan sosialisasi ini dilakukan selama 1 hari bertempat di Aula SMP St. Aloysius Niki-Niki. Metode yang digunakan adalah ceramah dan diskusi. Dampak dari kegiatan pengabdian ini adalah peserta dapat memahami konsep dan sistematika PTK, karakteristik masalah-masalah PTK, trik mencari referensi artikel ilmiah yang berkualitas dan cara menggunakan aplikasi mendeley, serta konsep dan sistematika artikel ilmiah dan trik mencari jurnal sasaran publikasi. Direkomendasikan agar kegiatan serupa pada kesempatan lain, tidak sebatas sosialisasi, tetapi dilakukan tindak lanjut berupa pelatihan/workshop atau pendampingan lanjutan tentang pembuatan proposal PTK, pelaksanaan PTK di sekolah, penyusunan laporan PTK, hingga pendampingan menulis dan publikasi artikel ilmiah.

Abstract

Smartphones nowadays have become a basic need for everyone because they provide many benefits and conveniences for users. People always want to have a smartphone with good quality. However, due to the lack of information along with the many types of smartphones in circulation, it often makes it difficult for users to choose a smartphone that suits their needs. To overcome these problems, it is necessary to have a method that can provide recommendations for appropriate decision-making for users. This study aims to apply the Analytic Hierarchy Process (AHP) method and sensitivity analysis in determining the priority order of smartphone selection by comparing one smartphone to another. The criteria for consideration are Facilities, Price, Battery, and RAM with alternative choices in the form of Xiaomi, Oppo, and Vivo brand smartphones. Data collection in this study was carried out by distributing questionnaires to 100 students of the Mathematics Study Program. The data were processed using the AHP method and sensitivity analysis. AHP is used to produce a more consistent ranking order of each alternative, while the sensitivity test is carried out to measure the stability of the calculation results if there is a change in decision-making. From the results of the analysis with AHP, it was found that Xiaomi was the first priority of the respondent's choice, followed by Vivo, and the last priority was Oppo with an inconsistency level of 0.02. Meanwhile, sensitivity testing shows that RAM is the most influential criterion for changing the order of alternative priorities, where Xiaomi remains the first priority, followed by Oppo, and Vivo is the last priority.

Abstract

Many studies related to the use of Augmented Reality (AR) in the learning process. However, not many researchers have studied the effect of using AR on affective and cognitive aspects in terms of education level. To uncover this problem, the researcher uses a systematic literature review (SLR) design. In this study, the SLR stage consisted of four stages (1) problem formulation; (2) literature search; (3) identification of the type of research; (4) information retrieval. The findings of this study reveal that the use of AR technology has an effect on cognitive and affective aspects at the elementary and high school education levels. Middle school is the level of education that mostly applies AR technology. This study provides a recommendation that AR technology can be a medium for learning mathematics that can be applied by teachers and students at the primary and secondary education levels.
