Abstract

Pembelajaran di kelas yang tidak interaktif dapat disebabkan mayoritas mahasiswa yang tidak mampu memahami materi dari dosen, sehingga tidak muncul umpan balik dari mahasiswa. Hal ini menjadikan dosen tidak bisa secara efektif mengukur tingkat keberhasilan pembelajaran. Makalah ini mengusulkan model aplikasi gamification pada smartphone untuk pembelajaran di kelas. Aplikasi dirancang untuk menunjang interaksi dosen dan mahasiswa di kelas. Proses perancangan aplikasi dilakukan sebagai penelitian desain melalui beberapa tahap, yakni identifikasi masalah, menentukan tujuan solusi, desain dan pengembangan solusi, demonstrasi solusi, evaluasi, dan komunikasi. Penelitian ini menggunakan metode kualitatif untuk dosen dan metode kuantitatif untuk mahasiswa. Metode kualitatif menggunakan wawancara untuk mengukur kesiapan dosen dalam menggunakan TI serta pengalaman gamifikasi dalam pembelajaran. Metode kuantitatif menggunakan kuesioner COLLES yang dikombinasikan dengan skala penilaian kesiapan Aydin dan Tasci. Kuesioner COLLES digunakan untuk mengukur capaian mutu, pengetahuan dan keaktifan mahasiswa dalam pembelajaran berbantuan aplikasi. Pengukuran dilakukan pada enam variabel, yaitu Tutor Support (nilai 3.98), Peer Support (3.94), Relevance (3.65), Interactivity (3.72), Reflection (3.42) dan Interpretation (3.57). Nilai rata-rata pengukuran berada pada rentang antara 3.5 dan 4.2, yang bermakna “siap namun perlu sedikit perbaikan”. Hasil wawancara dan kuesioner tersebut menjadi dasar perancangan model aplikasi gamification pada smartphone untuk pembelajaran di kelas.

Abstract

Global warming caused by greenhouse gas emissions, e.g. carbon dioxide (CO2), in the atmosphere is now becoming a very serious problem facing the world community. Carbon dioxide emission increase from year to year, thus a necessary effort to reduce CO2 is required. Amine-based absorption is one of the methods for post-combustion capture. Monoethanolamine (MEA) is commonly used for CO2 capture solvent. This study aims to measure protonation constant (pKa) of MEA from 30 to 60°C using the potentiometric titration method. The results show that the pKa values of MEA are in general agree with the literature data. For instance, the pKa value of MEA at 30°C is 9.83 and that obtained from the literature is 9.80. Comparison between those two values gives a deviation of 0.22%.

Abstract

Sugar is one of the main sources of sweeteners and is widely used in the community. As one of the main ingredients in Indonesia, sugar demand in Indonesia has always increased along with the increase of population and industry growth in Indonesia. Meanwhile, sugar production in Indonesia can not meet domestic demand. Technically, the process of making glucose syrup is relatively simple and can be done by small or medium industries. But in fact glucose syrup producers are almost big industries. This is due to the development of a simple and cheap machine for making liquid sugar. Therefore, it is necessary to develop equipment to produce liquid sugar made from raw cassava, which can be used by small industry to develop liquid sugar industry. The process of making liquid sugar from cassava is divided into three namely the process of making tapioca, liquification and saccharification process and the process of tanning & filtering and evaporation. In this paper we will discuss the design of tapioca processing equipment which is part of the liquid cassava production equipment made from raw cassava that can be developed by small industry. With this equioment, the community can design a small industry of liquid sugar processing. This equipment aims to process cassava into cassava slurry. It is developed by using the principle of grinding and solvent. The processing capacity is designed to be 300 kg / hour.
