Agriculture involves more than just increasing production. For the agricultural sector to be stimulated, a substantial number of agroindustries must be developed. The demand for raw materials will rise due to the agroindustries, resulting in favourable selling prices for farmers. Farmers will be inspired to raise the quality and quantity of their products to satisfy market demands and industry standards. On the other hand, sustainability has become a concern in agriculture and the food supply chain. The new concept of a circular economy and a green supply chain offers a production and consumption model that lengthens the life cycle of agricultural products and reduces waste. This paper examines and offers recommendations for advanced digital technologies utilization in the Agroindustry 4.0/5.0 to establish a sustainable supply chain and a circular economy.

The success of encapsulation to protect iron from inhibitor degradation or oxidation depends on many factors including the excipient characteritics. Glucomannan, a neutral heterosaccharide, has a potential for the excipient. To improve the excipient performances, glucomannan is deacetylated to remove the acetyl groups by reacted with Na2CO3. This deacylated glucomannan is subject to bead formation after iron loading. The alcohol solution is commonly used in bead forming as dehydration medium during the encapsulation process. The objective of this work was to study the effect of alcohol on the bead performance of encapsulated iron using deacetylated glucomannan. The bead forming was conducted by dropping the excipient into ethanol and isopropyl alcohol (IPA) solution at various concentrations (50, 60, 70, 80 and 90%) and two condition temperatures (27-30° and 7-10°C). The encapsulation samples were subject to yield (YE) and efficiency of encapsulation (EE). The concentration of alcohol showed a positive impact on the yield and efficiency of encapsulation. Ethanol has a better performance compared with that of IPA regarding yield and efficiency of encapsulation. The optimum of yield bead formation (69.67%) and highest EE (66.80%) were obtained at 90% ethanol. Temperature of dehydration did not affect the YE and EE significantly. © The Authors, published by EDP Sciences, 2018.

Fatmawati Pondok Labu Jakarta Selatan DKI Jakarta 12450 Indonesia Department of Refrigeration Air Conditioning and Energy Engineering National Chin-Yi University of Technology No. 57 Sec. 2 Zhongshan Rd. Taiping Dist. Taichung 41170 Taiwan (R.O.C.) PT Tri Jaya Teknik Jalan Alternatif Jl. Krajan II Warungbambu Karawang Timur Karawang Jawa Barat 41371 Indonesia

In this study, Aluminium 1100-H12 with 1 mm thick was welded using pin-less friction stir spot welding (PFSSW) and then tested via tensional shear test to determine the tensile shear load (TSL) characteristics of its welds. The results obtained revealed that the tensile shear load of the welds was influenced by the parameter variations among revolving speed, depth of tool, and residence time. The clout of 1400 rpm revolving speed showed good properties with the highest value of TSL about 53 MPa at a depth of tool of 0.4 mm and at 9s of residence time. The middle value of TSL was confirmed at about 35 MPa through 990 rpm of revolving speed, 0.3 mm depth of tool, and 5s of residence time. Furthermore, the lowest property of TSL was found at 775 rpm of revolving speed, at 0.2 mm depth of tool, and at 9s of residence time. The results showed the influence of the depth of the tool has significant clout on the tensile shear load, especially at 0.4 mm for each set of revolving speed and residence time. Each set of dwell time to the variation of parameters has no significant clout on the tensile shear load. Good tensile shear loads can be achieved in the range of 45-53 MPa at a depth of tool of 0.4 mm and a revolving speed of 1400 rpm, where the best is 53 MPa at a residence time of 9 seconds.

The digitalization in the 21st century has brought tremendous benefits in many aspects of human lives, including in education. It opens the door of observing the phenomena that are difficult to do in classrooms. As phenomena observation is a vital activity in learning science, the technology of augmented reality (AR) will help students digitally observe as many phenomena as possible during their learning process. In this study, a science book that is integrated with AR technology was developed. It aims to fill the gap in the literature of what components should be included in an AR-based science book, especially the learning resource that is suitable for STEAM education. The study was limited to environmental pollution and global warming topics. The results showed that the developed AR-based science book has met the eligibility criteria to be used in STEAM education. In terms of numerical viewpoint, the scores for the feasibility test were 96.09% and 97.65% respectively for the learning media and material validation. Therefore, the AR-based science book is considered as a valid learning resource from the expert assessment. In addition, teachers and students also showed positive perspectives towards the AR-integrated book.

作者： Pratama, Heru Berian Saptadji, Nenny Miryani Study Program of Geothermal Engineering Faculty of Mining and Petroleum Engineering Bandung Institute of Technology Indonesia Jl. Ganesha No.10 West Java Bandung40132 Indonesia

The main issue in the management of the two-phase liquid-dominated geothermal field is rapid decline pressure in the reservoir so that the supply of steam to the power plant cannot be fulfilled. To understanding that, modelling and numerical simulation used reservoir simulators. The model is developed on liquid-dominated geothermal fields are assessed in various scenarios of production strategies (focusing only steam cap, brine reservoir and a combination) and injection strategies (deep and shallow injection, centered and dispersed injection), with the calculation using separated steam cycle method. The simulation results of the model for sustainable production are production 25% from steam cap + 75% from brine reservoir, dispersed and deep reinjection with make-up wells from steam cap results 9 make-up well number. The implementation of production-injection strategy needs to be planned right from the beginning of exploitation so that the strategy can adapt to changes in reservoir characteristics. © Published under licence by IOP Publishing Ltd.
