Abstract

The chemistry lecture at Universitas Nurtanio needs teaching materials innovation to increase students' activity and learning motivation. This research aims to develop worksheets on the material of elements, compounds, and the periodic table and determine the validity and practicality. The stages carried out in this study are the define, design, and development stages. The validity and practicality data analysis used the moment kappa (k) formula. The average validity and practicality are 0.87 and 0.77, respectively, with very high criteria. The validity and practical result indicate that a guided inquiry-based worksheet can be applied as teaching materials on elements, compounds, and the periodic table in lectures.

Abstract

Alat charger untuk baterai berkapasitas 650 mAh menggunakan sel surya merupakan uji coba alat yang digunakan untuk charger baterai berkapasitas 650 mAh menggunakan energi matahari. Baterai 650 mAh ini digunakan pada drone. Alat charger menggunakan sel surya ini digunakan sebagai alternatif pengisian energi pada baterai. Alat ini dirancang dengan menggunakan resistor, kapasitor, dioda, saklar, baterai 650 mAh, LED, sel surya, IC lm317, dan trimpot. Perangkat berupa sistem analog yang menggunakan voltage drop dan memanfaatkan step up step down serta LED sebagai indikasi pengisian. Hasil uji fungsi dilakukan dengan cara mengukur intensitas cahaya menggunakan alat lux meter, baik pada saat beroperasi maupun tidak untuk mengetahui nilai intensitas cahaya. Masing-masing panel menghasilkan keluaran tegangan rata-rata 6 Volt DC dengan arus 200mA. Untuk memenuhi kekurangan tegangan, keluaran panel surya dimasukan terlebih dahulu ke modul DC-DC Step Up. Dari modul Step Up tersebut dihasilkan tegangan keluaran sebesar 12 VDC yang kemudian dipakai oleh modul charger untuk melakukan pengisian baterai Lithium-ion Polymer (LIPO). Waktu yang efektif untuk proses pengisian baterai menggunakan sel surya adalah pada waktu siang hari sekitar pukul 11.00 sampai pukul 13.00. Dari hasil uji fungsi yang dilakukan, alat bekerja dengan baik yang ditandai dengan LED berwarna merah yang mengindikasikan sedang terjadinya proses charging. Dengan demikian, alat ini bisa dimanfaatkan sebagai pengisian energi alternatif pada drone yang menggunakan LIPO yang memiliki keterbatasan waktu terbang. The charger for a battery with a capacity of 650 mAh using solar cells is one of tools used for a battery charger with a capacity of 650 mAh using solar energy that commonly used in drones. This solar cell is as an alternative charging energy for the battery. This charger is designed using resistors, capacitors, diodes, switches, 650 mAh battery, LEDs, solar cells, IC LM317, and trimpot. An analog system based on a voltage drop and utilizes step up step down and LEDs was used as an indication of charging. The testing was carried out by measuring the light intensity using a lux meter, both during operation and not to determine the value of light intensity. Each panel produces an average voltage output of 6volt DC with a current of 200mA. To meet the shortage of voltage, the output of the solar panel is first entered into the DC-DC Step Up module. From the Step Up module, an output voltage of 12 VDC is generated which is then used by the charger module to charge the Lithium-ion Polymer (LIPO) battery. The effective time for the battery charging process using solar cells is during the daytime around 11.00 to 13.00. From the results of the function test carried out, the tool works well which is marked by a red LED which indicates the charging process is occurring. Thus, this tool can be used as alternative energy charging for drones that use LIPO which has limited flight time.

Abstract

Penelitian ini bertujuan membahas pengenalan deteksi objek melalui platform transformasi digital sehingga diharapkan dapat berkontribusi terhadap pembelajaran anak sejak usia dini. Kemajuan teknologi tidak hanya dibarengi dengan dampak positif, tetapi dapat juga menimbulkan dampak negatif. Penggunaan teknologi digital di kalangan anak usia dini dapat menimbulkan kondisi yang kurang baik apabila terjadi pergeseran orientasi pemanfaatannya, karena teknologi digital banyak menyediakan fasilitas jejaring sosial, game online, chatting yang mengakibatkan anak lupa waktu, tidak kreatif dan tidak aktif bahkan dapat berpengaruh kurang baik terhadap jasmani dan rohani anak. Hal ini menjadi fokus peneliti, terutama anak usia dini. Salah satu kemajuan teknologi yang dapat mempengaruhi perkembangan anak adalah gadget. Pemanfaatan gadget dapat diarahkan sebagai platform pembelajaran anak usia dini untuk mengenal benda-benda di sekitarnya, misalnya hewan, tanaman, mobil, bangunan. Cara kerja deteksi objek adalah menerima masukan berupa gambar dan menunjukkan hasil klasifikasi sesuai gambar yang diterima. Diharapkan dari penelitian ini, anak usia dini dapat memanfaatkan kemajuan teknologi dan mengenal objek di sekitarnya.

Abstract

In this study, a comparative study was conducted on the use of the Google Classroom and Zoom Meeting platforms during online lectures held at Nurtanio University. The object of research is students from various study programs at Nurtanio University, totaling 82 people. Data were obtained from questionnaires filled out by students on a google form with an ordinal scale. The questionnaire is divided into three components (lecture implementation, lecturer capabilities, and facilities and infrastructure) with a total of 15 statement items that compare perceptions of using Google Classroom and Zoom platforms. Overall, students gave a perception of the "good" category on the three assessment components with an average score for the Zoom and Google classroom platforms respectively 4.07 and 3.90 in the implementation of lectures, an average score of 4.06 and 3.96 for lecturer capabilities, and an average score an average of 3.84 and 3.76 for facilities and infrastructure. To find out whether there is a difference in student perceptions on the two platforms, a statistical test using SPSS is carried out, namely the Wilcoxon marked rank test. The results obtained are that there are differences in student perceptions on the use of the two lecture platforms, namely the perception of students using Google Classroom is better than using Zoom as evidenced by the Asymp score. Sig. (2-tailed) = 0.007 and Z value = 2.692.

Abstract

Packaging is an important element in building a product's brand. Packaging plays an important role because it will always be associated with the packaged product and represents the sales value and image of the product. Product sales will increase if the packaging is attractive, and the product image is closely tied to consumers' opinions about the product. The method used in this activity is training, specifically direct support to partners. The overall objective of this activity is to provide training on how economic entities such as small and medium enterprises can develop product packaging so that the products produced are in high demand by consumers so that they can develop good business and can contribute to economic development. In addition, it also supports sales optimization to increase sales. Through this activity, partners share knowledge about packaging design and selling products online. Partners also receive guidance to improve their skills in presenting more attractive product photos. With changes in packaging design and sales methods, partner revenue has increased, and product shelf life has also increased. Scholars as PKM implementers can deploy their expertise to collaborate with the community.
