Indonesia is a tropical country and has many mountains with thousands of unexplored plant species, including chemical contents and biological activities. One of the genuses of plants that live in this tropical mountain area is the Rubus genus or Rosaceae. The type of plant (Rosaceae) is included in plants that have berry type fruits, which are small, soft, commonly eaten as fruit, colorful, and having important nutritional content. Some Rubus is reported to have strong anti-oxidant, anti-elastase, anti-tyrosine, anti-collagenase, anti-UV, and anti-aging activities and to have major phyto-chemical contents, namely compounds ofterpenoid, polyphenols, and flavonoids. The Rubus has a lot of benefits which make one of the doctors at UI research this.

Yesi Desmiaty in her dissertation examined this plant whose extract has anti-aging benefits. In this study, the stems, fruit, and leaves of the plant were extracted by using the Soxhlet tool to conduct research and to test whether it is true that the content in this fruit has anti-aging benefits for humans. In the research process, a separation and isolation process was carried out on the extract compound. The stratified extraction results showed that the methanol extract of R. fraxinifolius leaves has anti-elastase and antioxidant activity.

The results said that several species of the Rubus genus were reported to have anti-aging activity. Groups of compounds that are known to have anti-aging activity in Rubus fruit are triterpenoids, polyphenols, and flavonoids. Besides being spread abroad, it turns out that Rubus are also scattered in the forests and mountains of Indonesia. Based on reports both in publications and in the herbarium, there are 25 Rubus types spread throughout Indonesia.

The lack of awareness among Indonesians of mental health amid the Covid-19 pandemic situation can certainly cause special problems. Therefore, three students of the Ten November Institute of Technology (ITS) created Curhatin, an application for online psychology consulting services. By forming a team, they created an online psychology consultation service application.

The team leader, Bagas Juwono Priambodo said that the Indonesian people are still considered being less concerned about their mental health. Many people think that mental health consultation is not important. Even amid the ongoing Covid-19 pandemic situation, the psychological problems of the Indonesian people are increasing. Excessive worry is one reason for the emergence of mental health problems today. That is the basis of the team creating the application named “Curhatin”. It is a mobile android based application. This application is equipped with various psychological services that can help the community. The services provided are anti-stress tips, consultations with psychologists, stress healing methods, stress monitoring, and personal journal records.

The consultation services with psychologists will be carried out by sending messages, calls and video calls. People can freely choose according to their individual needs. The team also plans to coordinate with the Indonesian Mental Medicine Specialist Association. In the future, the anti-stress tips service features, stress monitoring, and several other tips will be presented in the form of videos and articles. Thanks to their great attention to the mental health of the Indonesian people through the application idea of Curhatin, Bano and team were successful in the INA IDEAthon Covid-19 competition held by the Ministry of Research and Technology / National Research and Innovation Agency (Kemenristek / BRIN). They have also been named as the 17 Best Ideas to defeat 5,590 ideas throughout Indonesia.


The Bandung Institute of Technology (ITB) team developed a device for disinfection of reusable Personal Protective Equipment -PPE and disposable PPE. This is motivated by a variety of cases of medical personnel infected with COVID-19 while on duty, even though they have been equipped with appropriate PPE and good usage procedures. The team analyzed that the possibility of exposure occurred because of PPE management, both when interacting with patients and when changing PPE.

The team created a device that uses ozone gas as a disinfectant. Chief researcher Sri Harjati Suhardi, PhD said, there are two types of tools that are used according to their uses. The first one is a disinfectant device that uses ozone mist to sterilize reusable PPE after use, such as hazard clothes, face shields, and safety glasses. Whereas, the second tool uses ozone gas for disposable PPE, for example masks and gloves, before disposal. Both become effective tools because they can kill the virus within seven or ten seconds according to studies in disinfection of microorganisms.

In its use, PPE is only stored in tightly closed containers and there is very little contact with medical personnel when doing the sterilization process. The consideration for the selection of ozone because it is safe for humans does not leave residues, and will be transformed back into oxygen. Now the tool is already in the prototype stage and ready to be launched for mass production. It is hoped that this PPE cleaning and sterilization container device will become an alternative solution to solve the problem of protecting medical personnel and hospital management.


The Ten November Institute of Technology (ITS) collaborates with Airlangga University Hospital (RSUA) to continue to produce innovative technology for handling the Corona virus outbreak. This time, the invented innovation is in the form of Ultra Violet ITS - Airlangga (VIOLETA) robot which is useful to facilitate the process of room sterilization for the care of Covid-19 patients. ITS Deputy Rector IV, Bambang,Pramujati PhD explained that the idea of creating the VIOLETA robot began when several ITS lecturers succeeded in researching the use of UV light to eliminate or inhibit the growth of microorganisms. This robot can also avoid physical contact with UV exposure because it is very dangerous when it comes to humans directly.

VIOLETA uses a UV light that is controlled remotely by using wireless control. This robot is effectively used at a distance of 1 to 2 meters to the object and takes 10 to 15 minutes to fully sterilize. One of the VIOLETA's research teams, Endarko added that in general, these UV lights have wavelengths of 200 to 300 nanometers. In practice and theory, the wavelength range can kill microorganisms well. This 30 watt UV light is healthier and safer than using disinfectants. This is because there are no residues left after the sterilization process.

As for the application in the Covid-19 case, the VIOLETA robot has the benefit of being able to sterilize the isolation space that has been used or the area that has been used in handling Covid-19 and without involving humans directly. One of the VIOLETA robot team programmers, Achmad Zidan Akbar said, the robot which weighs 30 kilograms uses the basic platform of the ITS soccer robot named IRIS. The VIOLETA also uses an inverter to convert the direct current from the battery into an alternating current which will turn on the UV light.


Air circulation in a building is an important aspect that must be considered when trying to design a building. Three students of the Department of Civil Infrastructure Engineering created an eco-friendly building designed with a concept of a termite nest that is able to provide better air circulation. According to one member of the team, Muhammad Yusril Bastian, currently, Indonesia has many environmental problems. Therefore, eco-friendly building exists to overcome these problems.

Yusril revealed that this eco-friendly building adopts the concept of a termite nest. This concept can circulate air from outside. In addition, this concept can also reduce the temperature of heat in the room. This concept was chosen so that the building feels cool without using an air conditioner. He also explained that the temperature from outside was reduced first. Afterwards, the air is channeled into the rooms in it, so the building will feel cooler. Termite nest building can reduce temperatures to ten degrees Celsius.

In terms of building materials, Yusril said that there were no specific criteria needed in the construction of this building. The building material chosen is almost the same as conventional buildings in general. He also mentioned several advantages, including being able to save electricity by 93 percent in comparison with the use of Air Conditioners (AC) and 21 percent compared to the use of fans. As for water usage, this building is able to save water usage by 100 percent compared to conventional homes. Thanks to these advantages, Yusril and his two friends won second place in the scientific writing competition at the Udayana University in Bali last February.


Indonesia's sea wealth is enormous and its sea area reaches 2.3 million square kilometers. If managed properly, Indonesia can be independent in producing sea fish without importing from other countries. In this regard, the student of the Sepuluh November Technology Institute (ITS), Alfian Bimanjaya tried to make a new breakthrough named the Fisheries Potential Information System -SIRIPIKAN in the international competition Esri Young Scholars Award 2020 last March. He won two achievements at the same time. He successfully came out as runner-up and he was favorite among the finalists.

SIRIPIKAN was made with the primary objective to provide geospatial information about the potential of fisheries to improve the effectiveness of fishing activities and fish distribution activities. In addition, SIRIPIKAN also comes with several spatial analysis features, such as proximity analysis, direction search, route, and travel time which are still rarely provided by other similar applications today. In making SIRIPIKAN, Alfian used remote sensing technology, specifically the Moderate Resolution Imaging Specter-radio-meter satellite imagery to determine the Potential Fishing Zones. Geographic Information System (GIS) Technology is also used to analyze and present geospatial information on the distribution of Potential Fishing Zones.

Alfian explained that from the features possessed, the use of SIRIPIKAN can be used by not only fishermen as a supplier of capture fish, but also distributors and fish traders. The community as fish consumers can also use this technology, as well as the government as the party that takes the policy. SIRIPIKAN still needs a lot of development, especially in terms of data updating. At present, information on Potential Fishing Zones is still available periodically on a monthly basis. In the future, SIRIPIKAN can provide Potential Fishing Zones information every week, even updated every day.


Amid the Covid-19 pandemic that spread throughout the world, a scarcity of Personal Protective Equipment (PPE) arises, that is needed by the medical team who stand at the forefront line in handling Covid-19. Responding to this, the Institut Teknologi Sepuluh November (ITS) Surabaya showed its contribution in suppressing the scarcity of the PPE on the market by producing Face Shield Mask needed by the medical team.

Head of Integrated Digital Design Laboratory of the ITS Industrial Product Design Department in Surabaya, Djoko Kuswanto said that the idea of making a Face Shield Mask was an active response to panic buying by the community on the impact of the outbreak of Covid-19, even though medical personnel were the ones who most needed this PPE. In the production of Face Shield Mask, ITS collaborates with the Indonesian 3D Printer Association. The production target of the Face Shield Mask is expected to meet 500-1,000 items every day.

This emergency PPE mask uses two types of materials, namely High Density Polyethylene (HDPE) and Polyethylene terephthalate (PET) plastic. This emergency mask must also be produced by paying attention to the safety of the material used. Djoko stressed that these masks are only for clinical institutions that need them. This free distribution has a flow of distribution procedures that are not arbitrary. For clinical institutions that need this mask must prepare an official request letter and attach it together with the online form provided.

Indonesian embassy in Madrid, Spain on Sunday (15/3) called on Indonesian citizens in order to obey the policy of local government which restricts outdoor activities for 15 days beginning on Monday (16/3) in order to reduce the spread of new types of corona viruses -COVID-19). The Indonesian embassy in Madrid requests Indonesian citizens to provide sufficient food and medicines and actively establish communication with the Indonesian representative office in Spain. This was stated by the Executive of the Social and Cultural Education Function of the Indonesian Embassy in Madrid, Ekalyptha Setyo Cahyono through a written statement received in Jakarta. During the period of isolation, the Indonesian Embassy in Madrid also requested Indonesian citizens, who are on holidays in Spain, to immediately return to Indonesia, remembering that all attractions and restaurants are suspended to operate in Spain.


After the Indonesian government announced that there were Indonesian citizens who were positive for the corona virus (Covid-19) some time ago, many residents were busy buying masks and hand sanitizers. So, the masks and hand sanitizers are becoming rare in the market. In fact, efforts to prevent the spread of the corona virus can be done with a clean and healthy lifestyle. One of them is by washing hands with soap. However, if it is outside and there is no water or soap, the choice is with antiseptic liquid hand sanitizer. Seeing this condition, one of the lecturers from the Faculty of Pharmacy, Gadjah Mada University, UGM, Dr. Ronny Martien, M.Sc., makes herbal Nano polymers hand sanitizer spray.

He makes herbal hand sanitizer spray Nano polymers. This product was made as an alternative to antiseptics because hand sanitizers are now rare and expensive in the market due to the outbreak of the corona virus in Indonesia. The raw ingredient is green betel leaf which is widely used as traditional medicine.Apparently, the development of a product called " Betel Infusion Nano polymer Spray " has been carried out by Ronny since last year. The green betel leaf was chosen as raw material because it has an antibacterial activity which is generally caused by bacterial infections such as Staphylococcus auerus and Escherichia coli. He also remarked that the use of many synthetic antibiotics cause bacterial resistance. Because it needs formulations from natural ingredients such as green betel leaf.

The hand sanitizer product made by Ronny uses Nano technology. The formulation in the form of nanoparticles is carried out because green betel leaves has relatively low solubility in water. According to him, the betel leaf infusion Nano polymer spray is made alcohol-free by formulating betel leaf infusion with chitosan. Therefore, he hopes that his creation can be an alternative solution in overcoming scarcity and the high cost of hand sanitizers on the market.
