Fresh-cut was kept at the temperature conditions with observed characteristics texture color their flesh measured water content, sucrose acidity, vitamin C, total carotene. Physical under conditions.Fresh-cut products stored in lower ±14-15 °C had optimum 4 days for 3 papaya.

Microcrystalline cellulose (MCC) is one of the derivatives produced as a result depolymerization part to achieve high crystallinity.When implemented in other polymers, crystallinity correlates with greater strength and stiffnes, but it can reduce water-holding capacity.The acid concentration hydrolysis time will affect acquisition water absorption capacity, both which have significance properties hydrogel filler.The study aimed evaluate select MCC generated from varying proportion...

Abstract Introducing smart greenhouse technology in tropical agricultural Indonesia has the potential to bring about substantial advantages, such as higher crop yields, decreased water consumption, and enhanced food security. Nevertheless, feasibility of this must be evaluated before it can widely adopted. The objectives study were evaluate viability using engineering economics software cost estimation model (SCEM), consider fixed variable for operational, effort developing supporting...

Abstract Precision agriculture serves as a crucial solution to address the challenges of food security and sustainability. It provides significant benefits enables effective monitoring throughout entire supply chain using technology-driven approach that prioritizes internet connectivity leverages big data. A noteworthy application precision is Mini Plant Factory, where plants are cultivated in closed systems with artificial lighting. The development Factory requires an economic feasibility...

Measuring consumer acceptance of food products is challenging, primarily because the process susceptible to bias. Several studies have reported that this challenge can be addressed through Kansei engineering verbal and nonverbal response measurements. Therefore, study aimed predict overall using artificial neural networks (ANN) engineering. A total 30 respondents participated in test nine different samples traditional spice-based ready-to-drink (RTD). The score responses, including...

The vegetables should be cultivated in an optimal way to obtain maximum yield. In tropical regions such Indonesia, the growth of are influenced by climate factors as humidity, temperature, nutrients and light. To gain controlled condition during periode, mustard plants could hydroponically a greenhouse. This study was conducted identify pattern (Brassica rappa var. Parachinensis L.) that planted greenhouse which is equipped with light control. aim this research determine best combination...

Abstract Oil palm empty fruit bunches (OPEFB) have not been properly utilized by most oil mills and communities in Indonesia. The processing utilization of OPEFB are still limited. Due to high cellulose contents, it potentially made into various bioproducts, especially as biomaterials. Therefore, a proper extraction technology is needed obtain level purity because alkaline treatment can solely remove part hemicellulose lignin. A higher content be obtained further chemical treatments through...

Abstract The freeze-drying of fruits is one alternative to increase the added value fresh fruit, extend shelf life which product, and still have properties like fruit. Osmotic dehydration pre-treatment can be applied before drying techniques produce a new maintain nutritional sensory quality, improve process. In this research, effects osmotic on performance quality characteristics freeze-dried strawberries were evaluated. Freeze-dried made using without pre-treatments by (OD) with method....

Local factors and global influences shape consumers’ perceptions through social media. In this regard, spice drinks as an agribusiness product have received increasing attention due to the Covid-19 pandemic. Therefore, understanding is crucial for promoting development of drinks.
