Miana leaves have various bioactive compounds and are widely used to treat various diseases such as fever, colds, coughs, headaches, asthma, constipation, and skin diseases. There are several types of miana plants, such as Coleus scutellarioides (L.) Benth., Coleus aromaticus Benth., Co...
The food freshness is one trending topic that currently studied to reduce the number of food waste. The development of food freshness film indicator is one technique that can be utilized to resolve the high number of food waste. The objective of this study was to evaluate the ability of cellulose nanofiber film that had been integrated with anthocy...
Innovations in adding spices to coffee are developing and many are being carried out to obtain new aromas and tastes as well as to enrich the properties of coffee so that it becomes a functional drink for the body. One type of spice that has health effects or values is cinnamon. Liberica coffee with cinnamon flavor can be an alternative to coffee-b...
The blend of standard Indonesian rubber (SIR-3L) and low density of polyethylene (LDPE) with a ratio of 50/50 (w/w%) had been prepared by varying the amount of divinylbenzene (DVB) and dicumyl peroxide (DCP). The properties of SIR-3L/ LDPE blends had been characterized using scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), an...
Desa Jati Mulyo menjadi salah satu desa yang pertumbuhan lahan kopi Liberika cukup tinggi, melalui bantuan bibit dari Dinas Perkebunan masyarakat mulai beralih dan fokus pada Kopi. Produksi bibit kopi serta upaya membentuk sentra produksi bibit kopi diperlukan penguatan pada penangkar bibit, sehingga dengan adanya penangkar bibit tersertifikasi dap...
Based on an extended theory of planned behavior (TPB), this study focused on five exogenous constructs (perceived benefits, facilitating condition, normative belief, behavioral belief, and control belief) that was established to predict behavioral intention and behavior of data-sharing. The research model was tested with 157 Indonesian researchers...
The purposes of this study were to determine: 1) the attitudes and motivations of
pre-service science teachers in learning Hess’ Law using multimedia based on
multiple representations (macroscopic, microscopic, and symbolic) of Hess’ Law;
2) the learning outcomes of the participated pre-service science teachers after
experiencing the learning throu...
[Development of Learning Multimedia for Polymerization Reaction to Improve Students' Science Literacy Ability] Mata kuliah Polimer di Prodi Pendidikan Kimia merupakan salah satu mata kuliah yang materinya banyak mengkaji reaksi polimerisasi. Kemampuan literasi kimia polimer mahasiswa pada materi reaksi polimerisasi merupakan salah satu kemampuan ya...
This study aimed to test a reflective model involving Technology Innovation Acceptance (TIA) and Organizational Innovation Climate (OIC) as predictors for Innovative Teaching Behavior with Information and Communication Technology (IT-ICT) among 533 pre-service teachers from 3 Indonesian universities. Four hypotheses were proposed in the current mod...
Introduction: The aim of this research was to formulate the microcapsules of Macaranga gigantea leaves extract with solvent evaporation method using Ethocel 10 cP and Eudragit E100 as matrix. Methods: M. gigantea leaves were extracted using ethanol 96%. This extract was dried by rotary evaporator. The microencapsulation process of M. gigantea leave...
This study evaluates the properties of particleboards made from palm oil stems by adding PP-g-MAH adhesives in the form of freeze-dried and pure samples. Modulus of rupture, modulus of elasticity, tensile strength, swelling thickness and absorption of water from the board was evaluated based on the Indonesian National Standard. Broken modulus and i...
