Zika virus (ZIKV) is a neurotropic flavivirus that can infect pregnant women and cause fetal brain size abnormalities. Despite significant efforts to find anti-ZIKV strategies, there is currently no vaccine or specific therapy available to treat ZIKV infection. Based on previous research, there are in vitro experiments on cathelicidin-derived peptides as antiviral drugs against Zika virus. In this research, an in silico experiment will be carried out, namely a computational study in the form of molecular dynamics simulations to understand the mechanism of Zika virus inhibition by cathelicidin-derived peptides (L-LL-37 and D-LL-37) and the stability of the ZIKV protein capsid macromolecule as the virus to be inhibited and cathelicidin-derived peptides as anti-ZIKV drugs as well as a comparison of the binding energy of a single protein-inhibitor complex to determine the effect of cathelicidin-derived peptides as anti-ZIKV drugs. Molecular dynamics simulations were performed on five systems, such as the L-LL-37 peptide, D-LL-37 peptide, ZIKV protein capsid, and a combination of ZIKV protein capsid with L-LL-37 peptide/D-LL-37 peptide using the GROMACS program. The molecular dynamics simulation results showed the ZIKV protein capsid + L-LL-37 peptide had the most stability and conformation of the five systems during simulation with RMSD at the value of about 0.4 nm, radius of gyration at the value of 1.74 nm, and SASA at the value of 118 nm2. Molecular dynamics simulation results showed the flexibility of ZIKV protein capsid + D-LL-37 peptide was more flexible than ZIKV protein capsid and with L-LL-37 peptide. Then, a comparison of the binding energy of Chain A and Chain B protein capsid complexes before and after being linked to cathelicidin-derived peptides with L-LL-37 peptide or D-LL-37 peptide were 1131.050 ± 65.985 kJ/mol, 1141.884 ± 66.915 kJ/mol, and 1037.351 ± 75.283 kJ/mol, respectively. It can be concluded that the D-LL-37 peptide can inhibit the Zika virus protein capsid."

"Trading activities, whether in traditional or modern markets, generate both solid waste and wastewater. This study aims to analyze the characteristics and composition of solid waste generated from traditional and modern markets and their potential reductions in Pasar Pondok Bambu and Pasar Cinere, based on waste generation, composition, and solid waste’s characteristics that are generated from both markets. The method used in this study is based on SNI 19-3964-1994 about Measurement and Collection Method for Waste Generation and Composition of Municipal Solid Waste Sample. Results showed that the average volume of solid waste generation from Pasar Pondok Bambu and Pasar Segar Cinere is 2.74 m3/day and 0.76 m3/day, respectively. The main components of Pasar Pondok Bambu solid waste are 65.56% garden and vegetable waste, 13.04% slaughterhouse waste, 7.34% plastic waste, and 7.28% food waste. Meanwhile, the main components of Pasar Segar Cinere are 58.77% garden and vegetable waste, 20.58% food waste, 9.60% plastic waste, and 3.76% paper waste. There is a chance to reduce the amount of waste in both traditional markets in order to reduce the waste load in landfills. Alternatives to reducing the amount of solid waste are through reducing, reusing, recycling, and composting. These alternatives are expected to reduce solid waste generation in both Pasar Pondok Bambu and Pasar Segar Cinere. In order to be able to be used as compost material, both sources of solid waste should add materials such as leaves from garden waste to increase the levels of carbon content. Based on solid waste composition, potential reduction waste in both Pasar Pondok Bambu and Pasar Segar Cinere is around 40%."

"In the period of 2004 to 2014 there was a significant growth of employment in the logistics sector in Indonesia. This reflects a rapid rise in the need for logistics activities to support outsourcing. Because there is strong competition in the sector, logistics services should be able to deliver both cognitive and affective customer satisfaction. Studies in logistic services have been mainly focused on service gaps, an aspect related to cognitive satisfaction in customers. Many studies have been conducted to evaluate logistics service quality using SERVQUAL and the Kano model. However, these are insufficient in addressing all aspects of logistics provision. Hence, a deep understanding of customer affective need (known in Japanese as Kansei) is required, to provide competitive advantage by modeling more comprehensive customer experiences based on perceived logistics services. This paper proposes a combined model of Kansei Engineering, Kano, and quality function deployment (QFD), which it is hoped will generate more innovative ideas for improvements related to customer emotional satisfaction and customer delight. A case study in supporting logistics services has been chosen to validate the proposed model, and a survey through face-to-face questionnaires involving 157 customers was carried out. The model was then validated, and through the House of Quality (HoQ) concept, some innovative improvement ideas are proposed. They include the use of apps for order confirmation and cancellation, the integration of Google Maps into the ordering system, pre-order booking, and a bilingual feature in the transaction menu. Thus, from a practical implication point of view, it is hoped that this study will provide guidelines to the managers of logistics services companies in capturing, measuring and analyzing customer emotional needs (Kansei), with respect to the service attributes which are highly significant to Kansei aspects."

This study aims to determine the composition and the right technique in the copolymer synthesis process from styrene and methyl methacrylate (MMA) to produce the most suitable paint product for coating materials. The focus of this research is the synthesis of emulsion copolymerization between styrene monomer and methyl methacrylate (MMA) monomer using a semi-continuous technique whose composition is varied to make paint applications with the addition of APS and SDS. In this variation, the surfactants are also varied so that there is one variation that does not use surfactants. The synthesis was carried out using a semi-continuous technique at a temperature of around 70°C - 78°C and an agitator speed of 300 rpm within 4 hours. After the paint was formed from the emulsion copolymerization synthesis process, several characterizations were carried out including temperature, pH, solids content, density, and viscosity. From this characterization, the results obtained included temperature between 70॰C - 72॰C, pH between 6 - 1, density between 1.08 - 1.163 g/mL, solids content between 0.0595 - 15.7895% and viscosity between 0.904 - 1.408 mPa.s. The products produced in this study were tested using UV light to see color changes in order to prove the quality to resist damage from UV rays of each product for paint applications. From these tests, it was found that the third sample product was the most feasible product because it could withstand UV damage and had the highest density, viscosity and solid content values."
