Tempeh (a traditional Indonesian food made from fermented soybeans) is a popular food in Indonesia.&nbsp;Known for its affordability and popularity in Indonesia due to its high in fiber and other nutritional values, Tempeh is commonly served as a daily food staple in the country.&nbsp;Despite its low cost and price, the making of traditional Tempeh is far from simple. It takes significant amount of effort and time to produce it. Especially after the COVID-19 pandemic, there was a growing trend among vegetarians to introduce Tempeh as one of the super foods and an alternative vegetarian option worldwide. In this paper, we introduce an automated Tempeh maker machine that reduces processing time by 50% and ensures better hygiene compared to the traditional methods. Notably, 93% of respondents during the exhibition expressed interest in learning more about Tempeh. The main goal of this invention is to introduce the Indonesian Tempeh Machine (InEM), a groundbreaking automated home-scale tempeh maker. To the best of the researcher's knowledge, no machine currently exists that can automatically reduce the time needed to produce tempeh ready for consumption. Traditional methods, which require meticulous preparation and packaging, are still essential in tempeh production and are labor-intensive. The development of this machine will greatly simplify the tempeh-making process, thereby increasing its market supply. This machine was designed, funded, built, and tested by Rinda Hedwig at both USC and the Computer Engineering Laboratory. Students from BINUS High School and chef Trias conducted the tempeh-making experiments in the kitchen, while Marcel Saputra handled the documentation. The invention has been registered under the simple patent No. S00202309393 for the Mesin Pembuat Tempe Otomatis Skala Rumahan.

One of the challenges that blind people experience is limited access to books. The production of printed&nbsp;braille books is very expensive because the price of the printer itself is around 3300 USD. After that, printed&nbsp;braille books are also less practical to carry around because they are thicker than ordinary books. The&nbsp;comparison is that 1 sheet of ordinary book can produce 3 sheets of printed braille book. To tackle the challenges of limited access to traditional braille books, we have developed a transformative&nbsp;solution: replacing traditional books by displaying braille electronic books with ‘.brf’ format using the BEE&nbsp;Braille Nusantara system. Our goal is to make a wide range of literature and information accessible to the&nbsp;visually impaired community through innovative technology. By digitizing traditional books, we can overcome&nbsp;the limitations of physical braille books, such as their production cost and time-consuming nature. Through&nbsp;our advanced conversion process, we transform these books into electronic format, optimized for&nbsp;compatibility with the BEE Braille Nusantara system. This enables blind people to access and read their&nbsp;favorite books with ease. BEE Braille Nusantara is a groundbreaking system designed to revolutionize the reading experience for the&nbsp;blind people. By leveraging advanced braille technology and user-friendly features, BEE Braille Nusantara&nbsp;offers a solution that makes electronic books accessible and enjoyable. With our system, user can access a&nbsp;wide range of braille-formatted books, eliminating the limitations imposed by traditional braille books.&nbsp;Through BEE Braille Nusantara, we provide an extensive library of electronic books stored in braille ready (.brf)&nbsp;format, overcoming the limitations of physical braille books. Our system streamlines the process of accessing&nbsp;and engaging with braille books, ensuring a seamless reading experience for visually impaired users. With BEE&nbsp;Braille Nusantara, we aim to empower the community by providing a cost-effective and efficient solution to&nbsp;the challenges of braille book production.

COVID-19 pandemic has posed serious risk of contagion to humans. There is a need to find reliable non-contact tests like vocal correlates of COVID-19 infection. Thirty-six Asian ethnic volunteers 16 (8M &amp; 8F) infected subjects and 20 (10M &amp;10F) non-infected controls participated in this study by vocalizing vowels /a/, /e/, /i/, /o/, /u/. Voice correlates of 16 COVID-19 positive patients were compared during infection and after recovery with 20 non-infected controls. Compared to non-infected controls, significantly higher values of energy intensity for /o/ (p ¼ 0.048); formant F1 for /o/ (p ¼ 0.014); and formant F3 for /u/ (p ¼ 0.032) were observed in male patients, while higher values of Jitter (local, abs) for /o/ (p ¼ 0.021) and Jitter (ppq5) for /a/ (p ¼ 0.014) were observed in female patients. However, formant F2 for /u/ (p ¼ 0.018), mean pitch F0 for /e/, /i/ and /o/ (p ¼ 0.033; 0.036; 0.047) decreased for female patients under infection. Compared to recovered conditions, HNR for /e/ (p ¼ 0.014)was higher in male patients under infection, while Jitter (rap) for /a/ (p ¼ 0.041); Jitter (ppq5) for /a/ (p ¼ 0.032); Shimmer (local, dB) for /i/ (p ¼ 0.024); Shimmer (apq5) for /u/ (p ¼ 0.019); and formant F4 for vowel /o/ (p ¼ 0.022) were higher in female patients under infection. However, HNR for /e/ (p ¼ 0.041); and formant F1 for /o/ (p ¼ 0.002) were lower in female patients compared to their recovered conditions. Obtained results support the hypothesis since changes in voice parameters were observed in the infected patients which can be correlated to a combination of acoustic measures like fundamental frequency, formant characteristics, HNR, and voice perturbations like jitter and shimmer for different vowels. Thus, voice analysis can be used for scanning and prognosis of COVID-19 infection. Based on the findings of this study, a mobile application can be developed to analyze human voice in real-time to detect COVID-19 symptoms for remedial measures and necessary action.

Three Indonesian traditional musical instruments consisted of angklung, bonang, and suling were created to be played automatically during exhibitions to promote and attract tourists to learn about Indonesia during the COVID-19 pandemic. The systems were driven by the use of motors controlled by minicomputers and microcontrollers that could be accessed using smartphones based on Android operating systems. The results showed that the error rate measured between theoretical frequency and frequency produced by the instruments is 0.03% ~ 3.34%, which is considered negligible to human hearing. The average response time of the whole instrument is less than 1 second so the harmony of the song played is considered good.&nbsp;Moreover, the selected songs chosen to be played are 100% accurate. It is also stated that 81% of the respondents are willing to learn and enjoy more about Indonesia after seeing the system.

Living healthy is a current lifestyle especially in big cities. People are concerned about the number of calories they consume per day, and they even hire nutritionists and personal trainers to help them in monitoring their healthy life. In this research, the researcher is using a calorie monitoring dining table with a revolving stand or tray on a table to hold condiments. This device, which is commonly called as Lazy Susan, is modified by adding Raspberry Pi and load cell sensor to calculate the number of calories transferred from serving plate to user’s plate. Users can select the menu and the Lazy Susan will rotate to serve the desired menu while also calculating the calories consumed by the user. The information will be transferred to the user’s Android smartphone and will be adjusted according to the user’s activity. The error reading rate of the system is 6% to 7% and the total price of the product is $1,308, which is cheaper than the “made to measureautomated Lazy Susan dining table” available in the market. Achievement:<ul><li>2022 granted patent (IDS000005391).</li></ul>

As one of the world's largest archipelago countries, Indonesia faces significant challenges in distributing wealth including basic infrastructures such as electricity and internet to some of its most remote islands. Due to its remoteness, people in this remote area mostly lived in poverty, which also lead to poor education quality. The digital library based on the Raspberry Pi "minicomputer" was created to address this issue. This device can store more than 2500 educational movies and e-books that can be viewed offline and has been demonstrated to be reliable even in areas with unpredictable electricity.
