Abstract

One of the tasks of the warehouse as a vital support unit for the distribution process and inventory of goods is sorting. Especially for cosmetic warehouses. Product sorting in warehouses so far is still done manually which can cause negligence and take time when collecting stored product data. A storage system is the process of placing and acquiring goods and products to and from a specific location within an industrial plant or warehouse. To solve this problem, the warehouse needs an automatic sorting tool. This allows employees to easily record products stored in warehouses without using a large number of staff. The method applied to this tool is microcontroller-based automation which includes hardware design in the form of conveyor design, flow charts, and board layouts. Software design includes listing code, block diagram explanations and system flowcharts. Testing system working tools such as barcode scanning, servo angle, infrared sensor and conveyor. The items used as experimental samples totaled 9 pieces with the categories of facial wash, lipstick, and shampoo. Based on the tests that have been carried out, the prototype of automatic sorting of goods is already working as expected.

Abstract

The establishment of an astronomical observatory requires a thorough evaluation of meteorological parameters and Night Sky Brightness Levels (NSBL). This research focuses on assessing the potential of Karanganyar as a site for astronomical education and new moon observations. To determine the NSBL in Karanganyar, satellite imagery was used, indicating favourable conditions. However, NSBL can be affected by light pollution and moon phases in specific locations. To complement the satellite data, additional measurements were taken using a Sky Quality Meter (SQM). The SQM values were processed using probability distribution analysis and showed a highest probability NSBL value of 17.22 mag/arsec2, while the maximum NSBL value reached 20.99 mag/arsec2. The NSBL derived from satellite data was 21.47 mag/arsec2. Our study shows that Karanganyar has predominantly high NSBL, suggesting low light pollution and excellent sky clarity in the region.

Abstract

The ability of teachers to create ICT-based learning media is low, despite ICT's potential to address shortages in practical equipment and facilities. This research aims to analyze vocational high school teachers' competency in utilizing ICT-based learning media and identify obstacles they face. Using a descriptive qualitative method, the study involves productive teachers, school principals, and heads of administration. It focuses on teachers with expertise in broadcasting, film, animation, and machining techniques. The research steps include problem identification, limitation, focus determination, data collection, analysis, and reporting. Findings reveal that the average competency of productive teachers in three vocational schools is good: 35.29% are at a basic level, 47.06% at intermediate, and 17.65% at advanced. Teachers learn to create ICT-based media through lectures (10 teachers), courses (6), workshops (14), training (10), and independently (3), with workshops being the most common. In practical learning, 100% of teachers use PowerPoint, 64.71% use animation, 23.53% use Moodle, and 5.88% each use Debian, Nginx, and PHP. Barriers include lack of facilities (17.65%), ICT mastery (17.65%), time (31.18%), and other reasons (23.53%).

Abstract

Laboratorium virtual dikembangkan karena kegiatan praktikum fisika terkendala oleh beberapa hal yaitu keterbatasan waktu, laboratorium yang kurang memadai, dan juga faktor keamanan. Sehingga dibutuhkan media untuk membantu agar siswa tetap bisa melakukan praktikum dengan secara online. Penelitian ini bertujuan untuk (1) Mengetahui kelayakan laboratorium virtual materi fluida untuk eksperimen online (2) Mengetahui presepsi siswa terhadap laboratorium virtual materi fluida untuk eksperimen online.Metode pengembangan produk yang digunakan dalam penelitain ini adalah Research and Development (R&D) model APPED. Adapun tahapannya adalah analisis, perancangan, produksi, evaluasi dan deseminasi. Teknik pengumpulan data menggunakan angket yang dibagikan kepada siswa kelas XI SMAN 1 Kedokanbunder sebagai responden. hasil yang diperoleh kemudian dianalisis dengan menggunakan teknik analisis deskriptif persentase.Hasil penelitian menunjukkan kelayakan laboratorium virtual sebesar 79,23% ahli materi, 91,84% ahli media, 90,77% ahli intruksional, 87,72% pada respon siswa. sehingga rata-rata yang didapatkan sebesar 87,39%. Demikian dapat disimpulkan bahwa laboratorium virtual yang dikembangkan layak untuk digunkan dalam pembelajaran.
