Crime is an action which is considered as a violation of law and can harm others. Nowadays, crimes has increased with erratic patterns. Therefore, crime prevention is necessary since it will occur based on the historical data. Data mining is a technique that can be used to predict crimes that will occur. According to the previous researches, data mining techniques have several methods that can be used to predict crimes by utilizing the data of crimes that have occurred. Hence, it is necessary to conduct a comparative analysis of classification algorithms in order to obtain accurate prediction results based on the crime data in Sleman regency. The classification algorithms analyzed in this study were k-NN, Naive Bayes, and Decision Tree. Based on the three algorithms, the accuracy of k-NN with k = 5 was 57.88 percent, with k = 10 was 59.49 percent, with k = 15 is 59.38 percent, with k = 20 was 60.18 percent, and with k = 25 was 61.57 percent. Meanwhile, for the Naive Bayes algorithm, the accuracy reached 65.59 percent, and the Decision Tree algorithm reached 60.23 percent. In conclusion, the algorithm with the highest accuracy was owned by Naive Bayes.
This study aims to analyze the work posture of employees by using Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) methods. In this study, the angle of the employee was calculated, and the results showed that on the body part B, the angle of the back movement is 77º flexion, the neck is 18º extension, and the leg is 39º, while the leg is not uniformly supported. One of the body parts, such as the upper arm is formed an angle of 65 ° flexion, the forearm is 13 ° flexion, the wrist is 0 ° flexion, and the wrist is in the intermediate range of rotation. Based on the results of RULA, a grand score is 7, categorized as Action level 4. Meanwhile, based on the results of REBA, the grand score obtained is 11, and also categorized as Action level 4. Based on the calculation of work posture using RULA and REBA methods, it revealed that the operator’s work posture has a high-level and dangerous risk. Therefore, the operator needs to immediately improve his work posture. In addition, due to the lifting position that was started with no squatting position, it causes waist injures, since it becomes the lift’s pedestal.
Data dari BPS menunjukkan masih sangat sedikit usaha yang memanfaatkan pemasaran online. Berdasarkan wawancara singkat dengan para pelaku usaha anggota OK oCE ADMA diketahui bahwa banyak UMKM yang terdampak selama pandemi COVID-19. Penjualan mereka mengalami penurunan selama pandemi berlangsung, karena mereka tidak dapat membuka usaha secara offline akibat adanya pembatasan sosial berskala besar.

Oleh karena itu, tim dosen IST AKPRIND mengadakan penyuluhan tentang pencahayaan dan ventilasi udara di dalam rumah agar anggota keluarga mereka tetap sehat, produktif, dan dapat bekerja. Kegiatan penyuluhan tersebut dilakukan dengan pemberian handout materi dan penyampaian materi oleh tim dosen tersebut, serta sesi tanya jawab untuk memperdalam pemahaman materi. Kegiatan tersebut dilakukan pada bulan Maret 2020 yang dihadiri oleh 36 peserta di rumah Ibu Kepala Dukuh Kalijeruk II. Kegiatan ini dapat meningkatkan pengetahuan ibu-ibu tersebut untuk merancang pencahayaan dan ventilasi udara yang baik di dalam rumah serta memberikan wawasan kepada mereka untuk menamam tanaman buah dan sayur di sekitar rumah untuk menjaga ketahanan pangan dan ekonomi keluarga.
