Abstract

Online buying and selling activities and renting goods are familiar to young people or college students. For instance, the Telkom University campus has a buying and selling forum (FJB Telkom) using Line social media platform as a buying and selling activity. However, Line social media primarily known as an instant messaging application, and as a result, the researchers conducted a survey among Telkom University students related to buying and selling activities on FJB Telkom and renting activities around campus. Based on the results of 105 respondents, it was found that 69,5% stated that FJB Telkom using the Line platform could have been more efficient due to the lack of feature needs for buying and selling activities. Therefore, this study aims to design a user interface (UI) design for the FJB Telkom application by adding rental features that can assist Telkom University students in buying, selling, and renting items activities around campus. UI design was conducted with the User Centered Design (UCD) method approach that focused on the characteristics of user needs. The UCD method included a testing stage or usability testing. The user interface of the FJB Telkom application was tested using prototype testing and the System Usability Scale (SUS). The test results obtained from respondents indicated that the UI design of the FJB Telkom application achieved an average SUS score of 85,5% and received an excellent grade on the SUS score. Thus, the user interface of the FJB Telkom application successfully build a system with high usability.

Abstract

The designed user interface is mobile-based which aims to help manage food waste, especially for Bandung area students. The user interface display contains education about food waste, food waste banks and food donations. It is hoped that the user interface display created can help in managing food waste. Food waste in Indonesia is very concerning, for example in the city of Bandung there are 772.69 M3/day, which is 44.51% of the total of various types of food waste in 2021. Therefore a solution is needed that can help manage food waste. By utilizing technology, we can provide education about waste using a smartphone. Then a user interface display design is made using the user centered design method. The user centered design method is needed because it has an interface design process that focuses on usability goals. This method begins with collecting user information through questionnaires, then analyzing user information and obtaining user needs, then creating user flows, wireframes, mockups, and prototypes. After that, a usability test is carried out using the system usability scale method to see whether the user interface display that is made can meet user needs. The result of the system usability scale score is 87,5 and is in the excellent category, indicating that the user interface is good.

Abstract

As digital technologies increasingly permeate the education sector, the need to safeguard sensitive personal data within early childhood education systems becomes paramount. In Indonesia, where the adoption of digital tools in education is rapidly expanding, these systems are particularly vulnerable due to the hybrid nature of their processes, varying levels of digital literacy among stakeholders, and a complex regulatory environment. This research addresses the challenge of securing Indonesia’s early childhood education systems by designing a minimized attack surface through the integration of ISO 27005-based risk assessment and the TOGAF enterprise architecture framework. ISO 27005 provides a systematic methodology for identifying, assessing, and mitigating information security risks, ensuring compliance with the Indonesian Personal Data Protection Law (UUPDP). TOGAF is utilized to structure the enterprise architecture, aligning IT strategies with institutional goals while embedding robust security measures across the digital infrastructure. The research methodology involves identifying critical assets and potential threats, evaluating these threats using ISO 27005, and developing a secure architecture tailored to the unique needs of Indonesian early childhood education systems. The proposed framework is validated through application in a case study involving several Indonesian early childhood education institutions. This approach not only enhances the security posture of these institutions but also aligns with cultural and regulatory considerations, offering a comprehensive solution for protecting vulnerable educational environments in Indonesia.

Abstract

Carbon has many benefits as an adsorbent, catalyst, drug delivery, energy, and it can produced from various resources, includinglignocellulosic biomass. One of the potential biomass for carbon material is bamboo. The particle size is usually inversely proportionalto the surface area and adsorption level; therefore, studying the particle size of activated carbon is essential. This research aims toproduce carbon and sulfonated carbon from andong bamboo to understand the effect of particle size on the characteristics andadsorption capacity. The method for this research was the pyrolysis of andong bamboo into sulfonated carbon bioproducts usingH2SO4 10N with variations in particle size of 60 and 100 mesh. The proximate analysis of activated carbon based on IndonesianNational Standard (SNI) No.06-3730-1995 includes moisture content, ash content, volatile matter content, and fixed carbon.Sulfonated carbon adsorption analysis was conducted on iodine, methylene blue, ammonia, chloroform, and benzene compounds.The result showed that the proximate parameters of activated carbon produced had met the SNI requirements. The adsorptioncapacity of activated carbon on the adsorption of iodine, methylene blue, ammonia, chloroform, and benzene was 421.71432.50mg/g; 20.3521.90 mg/g; 9.559.98 mmol/g; 10.1615.03%, and 4.63.83%, respectively. Based on andong sulfonatedcarbon data, it can be used as an adsorbent and renewable green catalyst.

Abstract

Lesser known wood species refers to the woods already utilized much by the communities but confined only one or two of uses, generally as sawn timber and merchant wood. Consequently, diversification attempts are necessary to impart more added values to these species. One of the possibilities for such is their uses for bioethanol manufacture. In relevant, research was already performed to look into the possible utilization of 10 local lesser-known wood species, which comprised pangsor (Ficus callosa Willd.), jengkol (Pithecellobium rouslatum Kosterm.), petai (Parkia speciosa Hassk.), mami (Maesopsis eminii Engl.), balsa (Ochroma grandiflora Rowlee), ki cauk (Pisonia umbellifera (Forst) Seem.), buru manuk (Litsea monopeIata Pers.), kei renghas (Buchamania arborescens Blume), kei bonen (Crypteronia paniculata Blume ) dan ki hampelas (Ficus ampelas Burm.f.), as raw material for bioethanol. In assessing for bioethanol manufacture, it necessitates initially the data/ information on basic properties of each wood species, particularly the chemical composition, which was examined through the wood chemical analysis in accordance with the accepted standar, i.e. Norman Jenkin, Indonesian National Standart (SNI) and TAPPI. Analysis result on those 10 woods revealed that the cellulose content varied about 42,03-54,95%, lignin 22,66-35,20%, pentosan 15,36-17,15%, water content 3,95-10,99%, ash content 0,56-2,89%, silica content 0,12-0,84%. Solubility in cold water 1,29-5,55%, solubility in hot water from 4,41-11,19%, solubility in alcohol-benzene from 2,95-4,60% and solubility in NaOH 1% 10,35-22,89%. For bioethanol manufacture, it is desired that the woods base high values of consecutively cellulose and pentosan content, and solubility in NaOH 1%; and concurrently have low content lignin, ash and silica, low solubilities in cold water, hot water and alcohol benzene. Judging from those criteria and aided by the statistics interpretation, it indicates that 8 out of 10 species were technically prospective as raw material for bioethanol, i.e. from most until the least being kei rengas, mami, petai, jering, balsa, ki hampelas, ki cauk, and burumanuk, respectively. Meanwhile, kei bonen and pangsor are regarded as unsuitable for bioethanol.
