Application of Pulsed Electric Field for Inactivation of Yeast S. cerevisiae in Apple Juice
Authors: Eshtiaghi M N , Nakthong N 
Published: April 2021

Abstract
Pulsed electric filed (PEF) is a non-thermal food preservation method as alternative to traditional thermal method. The effect of pulsed electric field (PEF) on inactivation of yeast Saccharomyces cerevisiae (S.cerevisiae) in apple juice containing different sugar concentration was studied. The results of this study have shown that, using PEF, the yeast could be inactivated at room temperature (20°C). The inactivation effect of PEF was dependent on pulse number, field strength, and pulse width as well as sugar concentration. Pulse numbers less than 20 pulses (at 12.6kV/cm) had no or very less effect on yeast inactivation. Increasing the pulse number up to 400 pulses resulted about 3 logs yeast inactivation. The most important factor for yeast inactivation was the field strength (10 to 30 kV/cm). Whereas, at 10.2 kV/cm and 100 pulses, less than 2 logs yeast inactivation could be achieved, was the yeast inactivation at filed strength of 30kV/cm and 100 pulses about 5 logs. At given field strength and pulse number, longer pulse width (1 to 2.5 μF) affected positively the inactivation of microorganism. In contrast, increasing the sugar concentration in apple juice higher than 20% negatively affected the inactivation of yeast during PEF treatment at given treatment conditions.

Abstract
In order to enhance the likelihood of bone healing process from fracture, currently bone graft combined with osteocytes is a new alternative in promoting new bone formation. Silica-based nanoparticles had been proven to induce intrinsic biology activity, especially in promoting bone-formation and differentiation of mesenchymal stem cells towards osteocytes. Previous studies had shown positive results of new bone tissue formation by incorporating SiO2 nanoparticles synthesized using TEOS. In this current study, the experiment was using micropatterning technique, with PDMS as the substrate, which was coated by SiO2 nanoparticle powder with the particle size distribution between 150nm-450nm. The effect of SiO2-coated PDMS on (Wharton’s jelly mesenchymal stem cells) hWJ-MSCs viability was evaluated using MTT cytotoxicity assay for 1, 3, 5, and 7 days, which was compared with two treatments: cells grown with SiO2 powder without patterns and cells on 96 well plate). The MTT assay result showed that SiO2-coated PDMS micropattern was non-toxic to the cells and had the highest increase in cell viability for 7 days in comparison to the two controls used.

Abstract
The performance of personal protective equipment fabrics for COVID-19 health care practitioners was improved by polyvinyl alcohol (PVA) coating. The PVA enhances fabric’s resistance to body fluid penetration, on the other hand, also increases its hydrophilic properties. However, hydrophobic is required to prevent microdroplets and body fluid wetting on the fabrics. The hydrophobic effect was increased by immersed the fabrics in silica nanoparticles that resulted in a water contact angle of 133.41° ± 10.8°.

Authors: Wanqi Zhang 
Published: April 2021

Abstract
Bulk RNA-seq and single cell RNA-seq (Sc-RNA) seq are two well-known methods and are broadly used in biology areas. Even though the two ways are all starting from the mRNA level to do the transcriptional analysis, many differences still show in them, but the differences which are critical for researchers to judge and consider were not addressed clearly in the past studies. Here we summarized the principle, workflow and data presentation of the two methods and compared them comprehensively, which shed a light on the application of high throughput sequencing technique for researchers.
Lockdown strategy worth lives: The SEIRD modelling in COVID-19 outbreak in Indonesia
Authors: Nurlaila I , Hidayat A A , Pardamean B 
Published: April 2021

Abstract
Lockdowns, despite their conflicting restrictions and consequences they might offer when enforced as a national strategy, are deemed to be suggestive for a prompt conquer to the Coronavirus Disease-19 (COVID-19) outbreak. There have been some success stories such as in China, South Korea and our ASEAN member fellow, Vietnam, which exhibited extremely fallen numbers of COVID-19 cases post the enforcement of lockdown. Indonesia, however, remains in the crux of dispute whether or not the lockdown is opted to force COVID-19 transmission down under control. We, in this respect, employ the most popular model which has been broadly applied in the field of epidemiology, referred to as SEIRD (Susceptible, Exposed, Infectious, Recovered, and Death), the extension form of an age-structured SEIR, where the Death (D) is included to provide more factual situation. We modify the I (Infectious) fraction as symp-tomatic (Is) and asymptomatic (Ia) infectives. There are three lockdown scenarios simulated in our modified SEIRD with the starting date are 26 April 2020 when the immediate lockdown was enacted-and a-week and two-week-gaps, respectively. We figured out that by stipulating the lockdown without delay (26 April 2020), the new cases could be kept below 10,000. A week delay escalates case number to 5,000 and delay for one more week results in beyond 20,000 new cases. Furthermore, when the intervention is delayed following the delayed lockdown, normalization would demand a longer period within which dealing with more critical and dying patients is unavoidable and should be more anticipated.

Published: April 2021

Abstract
Some areas in Indonesia often lack clean water even occur drought if the dry season strikes. However, several other regions of Indonesia have pure water abundance despite the dry season. Based on this problem, the authors aimed to design a mobile application of a smart water supply chain based on the Internet of Things (IoT) for admin and users. The app was Control Your Water (C_Water) application. The app developed aimed not only to detect water shortage quickly but also to accommodate online water purchasing. By installing sensors in the water reservoirs, the admin could find out the supply of clean water in the tanks. Information had obtained from the sensor will go to Microcontroller, then the Microcontroller will send it to the database via Wifi. The mobile application displayed information based on data in the database. The authors proposed a data backup process to prevent data loss. The authors designed a water reservoir consisting of positions of ultrasonic sensors and a division of water level. The result of this research finds that this design helps the government (admin) to overcome the problem of real water shortages that occur in Indonesia.
Supply chain green productivity improvement for sugar industry
Authors: Asrol M , Purba F 
Published: April 2021

Abstract
The sugar industry has a vital role in meeting domestic demands; therefore, it is crucial to increase productivity and supply chain efficiency. Productivity improvement should not only focus on economic efficiency but also the environmental impact called the principle of green productivity. This paper aimed to discuss the potential implementation of green productivity improvement activities and determine the level of green productivity that has been achieved in the supply chain of the sugar industry. The analysis began with supply chain configuration analysis, analysis of seven waste sources with Green Value Stream Mapping (GVSM), and inference of the green productivity level with Fuzzy rule-based. The results of the supply chain analysis show that two activities required to be analyzed for productivity, namely the sugarcane cultivation and the sugar milling processing division. The green productivity index in the current state of plantation supply chain activity was 0.90 and processing was 0.61. Green productivity improvement with good housekeeping and efficiency resulted in a GPI of 1.81 for plantation supply chain activities and 2.30 for processing. The fuzzy inference shows an increase in green productivity in the supply chain processing activities from a bad label to normal.

Sensitivity analysis for wind-driven significant wave height model in SWAN: A Sunda Strait case
Authors: Wurjanto A , Mukhti J A 
Published: April 2021

AbstractSunda Strait is one of the most important straits in Indonesia since it connects two major islands of Indonesia as well as two oceans. Due to its high importance, it is essential to have a well understanding of significant wave height within the strait. However, there are currently no long-term significant wave data from buoy records in Indonesia. The available fine-resolution meteorology-oceanography (metocean) data around the Sunda Strait is also not as fine as other locations in the world. Therefore, hydrodynamic modelling is essential to obtain significant wave data that completely covers the strait. The aim of this study was to perform a sensitivity analysis based on Sunda Strait SWAN significant wave height model In the research, we performed a sensitivity analysis on a significant wave height SWAN model using various spatial resolution of wind forcing from the ECMWF ERA5 database. The analysis is essential to obtain the coarsest acceptable metocean data for modelling. Our result shows that higher spatial resolution of wind forcing gives better agreement with the ERA 5 wave data. For the Sunda Strait case, we recommend using no coarser than 0.5 degrees of spatial wind forcing resolution. However, we also found that the modelling result, along with models from past studies, still underestimates the reported wave height data in extreme conditions.

Abstract
The demand for fresh aggregates increases as the number of road maintenance and/construction project increases. However, continually mining fresh aggregates will result in irrecoverable environmental damage, and thus, engineers are looking for alternatives aggregates that are more environmentally friendly to be used. The paper discussed the usage of several recycled materials that were mixed with hot mix asphalt (HMA) to be used as surfacing pavement layer, including coconut fibre, Styrofoam, crumb rubber, and recycled asphalt pavement (RAP). A number of tests, which are Marshall, Cantabro Loss, and Indirect Tensile Strength tests were used to evaluate the performance of the asphalt mixtures that were mixed with recycled materials. Both coconut fibre and RAP were mixed as filler or substitute for fresh aggregates, while both Styrofoam and crumb rubber were melted and mixed with the binder. It is found that best amount for coconut fibre, RAP, Styrofoam, and crumb rubber to be added to the HMA are 0.6% of total binder weight, 100% of coarse aggregates, 2.5% of the binder weight, and 3% of total mixture weight, respectively.

Published: April 2021

Abstract
The research aimed to review issues related to visual communication synergy and sustainability in a brand. The main problem was how the message through visual communication could work precisely and quickly so that the delivery of the main message could be delivered without errors because the visual nature was very immediate and could not lie. This research used qualitative methods, namely descriptive-analytic, with a deductive as well as an inductive approach to get fairly basic findings, to reduce or minimize errors or deficiencies in visual communication. The results and discussion show that building a brand needs to be sustainable visual communication by creating functional, emotional, and expressing themselves. In conclusion, the main goals and objectives of communicating brand identity are to build, maintain, and strengthen the relationship between the brand and its customers. The brand as a symbol encapsulates all visual elements connected to brand value as individuals. So, the integration of visual communication and sustainability can be a synergy to enhance brand values.
Multi-stakeholder engagement in the Indonesian Sustainable Palm Oil (ISPO) framework
Authors: Dewi G D P 
Published: April 2021

Abstract
There has been an increasing concern in the development of sustainability in Indonesia. Indonesia’s sustainability policy through Indonesian Palm Oil Sustainability (ISPO) and recently Presidential Decree Number 44 of 2020 on Certification System for Sustainable Palm Oil Plantations prove the government’s seriousness in managing palm oil. Growing global market demand requires the expansion of oil palm plantations. Unfortunately, land expansion can cause environmental hazards, such as deforestation, loss of biodiversity, increased greenhouse gas emissions, and green land damage. On the other hand, the threat to sustainable development in the palm oil industry and pressure from stakeholders for more responsible industrial practices require sustainable production activities and minimize environmental and social impacts through sustainability principles. The government, companies, smallholders, palm oil associations, and INGO/NGO strive to build synergies in finding strategic solutions under the ISPO certification scheme. This article explores the involved actors in the palm oil industry and the relationship pattern between actors. Methodologically, the author uses a qualitative method and multi-stakeholder approach to invent how actors deal with sustainability issues in the palm oil industry and carry out sustainability commitments. The results show that Indonesia faces economic, social, and environmental imbalance. In implementing ISPO certification, Indonesia has involved all multi-stakeholder actors: state, company, IGO, and civil society.

Abstract
This paper aims to highlight the response of Association of Southeast Asian Nations (ASEAN) towards COVID-19. COVID-19, which is known as the Novel Coronavirus originally from Wuhan, a city in China and has been spreading to more than 200 countries in the world within a very short time. World Health Organization (WHO) asserts that COVID-19 has been a global pandemic. It has reached out to all continents in the world. Using primary and secondary resources, this paper argues that ASEAN has significantly responded at the regional level to mitigate the pandemic. At the national level, ASEAN member states have responded it with different policies based on their domestic socio-economic, security, and political circumstances. Singapore, Philippines, and Malaysia are the countries with the highest cases of COVID-19 implementing a lockdown policy. Thailand and Indonesia apply a local lockdown policy. While Cambodia, Vietnam, and Indonesia implement social distancing policies to protect their citizens from COVID-19. As a result, Vietnam and Malaysia succeed in suppressing the growth of COVID-19 cases. Meanwhile, the COVID-19 cases in Singapore and Indonesia, despite the government efforts to stop its spread, continue to increase as of June 2020.

Published: April 2021

Abstract
Nowadays, more than ever, plastic waste becomes a major problem for almost every nation in the world, including Indonesia. Creative solutions are needed to be the answer to overcome this urgent issue. Although there have been many attempts to create better waste management, these ongoing efforts are still far from the expectation. Therefore, every sector needs to collaborate to be part of the solution, including the education sector. The young generation is fertile ground for the birth of innovative ways to reduce plastic waste. This research aims to show that everything, even things as old as historical artifacts, can be a source of inspiration to overcome the plastic waste problem in Indonesia. However, an appropriate skill set is needed to extract this local content and make it suitable for the current digital society. This qualitative research is conducted through a case study using lateral thinking mode to prove that all things can be the source of inspiration to generate ideas. We can conclude that ideas can come from anywhere in the form of anything. Even though historical artifacts come from a long time ago, and even some have been around for hundreds of years, they possess unique local ingenious capacities.
