Abstract

Bio composite matrixes have been developed from several biomaterials, such as starch. One of potential resources is starch isolated from cassava bagasse still consisting 30-50% of starch. Reinforcement material may be inserted into bio composite to tough and reduce the drawback of the starch-based bio composite or bio plastic. Microfibrillated cellulose of bamboo (MFC) can be used as toughening filler for composite matrix. However, surface modification of material could be employed to alter its properties, such as acetylation of starch-based bio composite and

microfibrillated cellulose. The acetylation was executed by using glacial acetic acid (GAA) catalyzed with sodium hydroxide. This paper investigates optimum condition of acetylation for bagasse starch (BS) and bamboo MFC in different weight ratio of GAA to BS or MFC (1:1, 2:1, 3:1, 1:2, 1:3), temperature range of 30°C to 70°C, and pH range of 7 to 11. Data were resulted from degree of susbtitution for each running. The optimum condition of acetylation of BS was obtained at temperature of 50°C (for BS) and 30°C (for MFC), pH of 9, and 2:1 ratio. This acetylation was confirmed by fourier transform infrared spectroscopy and scanning electron microscope. © The Authors, published by EDP Sciences, 2018.

Opening Address

Selamat Datang and Welcome to all participants of the RSCE 2017. On behalf of both Scientific and Organizing Committees, it is my great pleasure to welcome all local and international participants to the 24

th

Regional Symposium on Chemical Engineering 2017 and to the beautiful historical city of Semarang-Indonesia. This event is organized by the Department of Chemical Engineering, Faculty of Engineering, Diponegoro University-Semarang, Indonesia. This conference is an annual conference of the Chemical Engineering Institutions of the South East Asian Nations, which have attracted wider participation from all around the world.

Bringing its theme “Innovations in Chemical Engineering Towards the Applications in Food, Energies and Materials”, the conference aims to bring all prominent scientists, researchers, inventors and innovators as well as industrial players together in one place so that we can share and exchange ideas, knowledge and expertise, widen networking among each other, present research findings, promote new technology and explore any potential benefits that might contribute to the new brighter and better future. The scientific committee carried out a challenging task in evaluating the large number of submitted papers, considering their scientific merits through detailed reviews, discussing, and selecting the best papers. These high quality papers are presented in the two days program consisting of five keynote speakers and eight (8) parallel technical paper sessions.

I would like to express our fullest and warmest gratitude to all participants, presenters, technical reviewers, and all collaborative partners for the supports. I hope that your contribution in RSCE 2017 will be a fruitful and long lasting one that envisioned continuous success of future RSCE events. I would like to extend my gratitude to all the committee members who have been working very hard in ensuring the successful of the conference.

Finally, I would like to apologize for any inconvenience and weaknesses that have been experienced during this conference. I sincerely hope that all the participants will get the benefits from the academic and cooperative experiences during RSCE 2017. We wish you a pleasant and memorable stay in Semarang and Indonesia.

Thank you.

Banana is one of the top produced crops in the Philippines, and among its cultivars is the Musa balbasiana, commonly known as saba. Due to its high moisture content, saba is perishable and one of the methods to increase its shelf-life is drying. The shelf life of saba can be extended up to six months when dried to 12% moisture content. The research focuses on the e ect of banana maturity and choses a mathematical model which will best t its drying kinetics. The banana samples, the unripe and ripe saba, were bone-dried without pre-treatment using a hot-air tray drier. To produce repeatable data, three trials were done for temperatures 40°C, 50°C and 60°C. Among the three mathematical models used in the study, the treated data for both unripe and ripe saba best t the Laplace Transform Model. Using Lagrange interpolation, the time per trial was computed; unripe saba dried at 50°C achieved the ideal moisture content in an average time of 87.5574 minutes for the three trials while that of ripe saba dried at 40°C achieved the same moisture content in an average time of 88.8619 minutes for the three trials. With the increase in temperature, the discoloration decreased indicating an enzymatic character ofbrowning.

Abstract

Virgin coconut oil (VCO) has become one of the most prominent high-value coconut product in coconut producing countries because of its versatility. This research attempts to design a fresh-dry process based on the Low-Pressure Oil Extraction Method for the production of VCO to reduce the settling time of the oil after extraction, that usually takes 1-2 weeks. Di erent parameters, such as drying temperature, centrifuge speed, and centrifugation time were varied and analysed.

Three mathematical models were examined to describe the drying behaviour of the grated coconut meat at 65, 70, and 75°C using a tray dryer. A VCO production fresh- dry process based on the Low-Pressure Oil Extraction Method was developed through the employment of a centrifuge. The modi ed method lessens the settling time while still producing standard quality VCO. As predicted by the Laplace Transform Model, the shortest time for the comminuted coconut meat to reach a moisture content of 11% at which oil from nuts can be extracted using low pressure is at 29.07 minutes using a tray dryer. The best setting of VCO production using the modi ed method is at a drying temperature of 70°C and at 2700 RPM and 60 minutes of centrifugation as it produced the clearest oil with a yield of 92.84 % v/v and a recovery of 18.43%. The produced VCO was tested for free fatty acid (FFA), moisture and volatile matter, colour, peroxide value, and iodine value, and the results are 0.03%, 0.11%, 0R/0.3Y, 0, and 5.77, respectively, which all passed the Philippine National Standards for VCO.

Microbial fuel cell is an ecological innovative technology producing bioelectricity by utilizing microbes activity.

Substituent energy is produced by changing the chemical energy to electrical energy through the catalytic reaction of microorganism. The research aims to nd out the potency of bioelectricity produced by microalgae microbial fuel cell technology by utilizing the combination of tapioca wastewater and microalgae cultivation. This research is conducted through the ingredients preparation stage – microalgae culture, wastewater characterization, membrane and graphite activation, and the providing of other supporting equipment. The next stage is the MMFC arrangement, while the last one is bioelectricity measurement. The result of optimal bioelectricity production on the comparison of electrode 2 : 2, the power density is 44,33 mW/m2 on day 6, meanwhile, on that of 1 : 1, 20,18 mW/m2 power density on day 1 is obtained. It shows that bioelectricity can be produced from the combination of tapioca wastewater and microalgae culture through the microalgae-microbial fuel cell (MMFC) technology.This research is expected to be a reference for the next research particularly the one that observes the utilizing of microalgae as the part of new and renewable energy sources.

Abstract

Cassava is one of the most widespread starchy tuberous roots in Indonesia, being one of the typical plants used in the starch market. However, due to the high cyanide content (338.41 ppm), these roots become a poison if they are unsuitably processed. Therefore, a detoxi cation process is needed to reduce the cyanide level to the safe level for human consumption (10 ppm).

This study was focused on (i) the investigation of the detoxi cation potential of fermentation with Lactobacillus plantarum (L. plantarum) on the cyanide level of wild cassava tubers (Manihot glaziovii) and (ii) the optimization of the fermentation time and bacteria cell number in the starter culture. The fermentation was performed for di erent periods of time (12, 24 and 36 h) and various initial bacteria cell number (7x1010, 7x1011, 1.05x1012, and 3.5x1012 L. plantarum cells). The results showed a signi cant decrease of the cyanide level, 97 % of cyanide degradation being noticed after 36 h of fermentation for an initial bacterial cell number of 3.5x1012 cells. Hence, the strong point of the study consists of a noteworthy reduction of the cyanide content in wild cassava in short periods, whereas the protein content was increased (from 1.5% to 3.5%) in Modi ed Cassava Flour (MOCAF).
