Published: February 2021

Abstract
This research is research and development on the form of experiments in the laboratory and aims to develop cassava products into noodles and testless bread with a touch of technology (technopreneurship). So far, cassava in Makassar is very abundant although not seasoned and the price is very low because the utilization by the community is still limited. Almost all communities in rural areas have cassava gardens. Therefore it is necessary to innovate its product development by being given a touch of technology-based technopreneurship through research. The results must be socialized so that the benefits are better and can be known by the community as raw materials for businesses that can be processed to be more productive to improve people’s lives. Experimental research has been carried out in the PKK laboratory and continued its development and application in the field. It has been started from PNBP research in 2017 and continued in 2018 with PDUPT research in the laboratory and its application on the field in 2019. The research began of an experimental trial to obtain a prototype model of noodle and white bread products from cassava which continued development and application on the field to obtain the final product model that the public likes and is suitable for production and marketing.

Published: February 2021

Abstract
The comparison of optimum conditions for lead (Pb) analytical method using dithizone and EDTA complexes in Eucheuma Spinosum (Eucheuma Sp.) was measured using a standard addition method, where the standard solution of Pb2+ was added to the sample to reduce noise. Additionally, UV-Vis spectrophotometer was used with dithizone and EDTA complexes in Eucheuma Spinosum, where Pb2+ ions in both complexes were measured. Both complexes were first developed to determine the optimal pH that would measure Pb2+ level in Eucheuma Spinosum. The most favorable pH level for such measurement was pH 8, at which pH activity was most stable, and the most favorable complex was dithizone complex, with a regression value closer to one than that of EDTA complex.

Abstract
It is probably fair to say that English language teaching in Indonesia’s universities has not seen significant success. Plethora of studies reported that the most common problem found in college English teaching is unskilled lecturers including the lack of integrating technology into their teaching. In fact, in this digital era, an ideal English lecturer has to have deep understanding of Technological Pedagogical Content Knowledge (TPACK) to create effective teaching. Therefore special treatment is needed to upgrade their knowledge and Lesson Study is believed to be the impactful professional development on teachers’ knowledge. This article reports on a case study regarding changes on three English lecturers’ TPACK after engaging in Lesson Study project. Those lecturers were voluntarily recruited for the case study. The findings show that Lesson Study broadened English lecturers knowledge of content, pedagogy, technology and the combination of these domains.

Published: February 2021

Abstract
Probabilistic thinking of each individual in solving probability tasks is different. Different mathematics ability also causes different process of student thinking probabilistic. This study aimed at describing the profile of probabilistic thinking of high school students with low mathematics abilities in solving probability tasks. This qualitative research was a case study. The subject in this study was a female student in 11th grade of science that had learned probability and had low mathematics ability selected based on mathematics ability test. The subject was given Problem Solving Tasks then she was interviewed based on her written answers. Data credibility used time triangulation. The results showed that in solving probability tasks, subject used personal experiences found in her own family and extended family. The subject used intuitive strategy that tended to use heuristic thinking patterns by performing attribute substitution process. In this case, subject gave a non-statistical response. The results of this study can complement the existing theories and become input for teachers to use approaches and strategies in learning that can accommodate the probabilistic ways of thinking of high school students in solving probability tasks.
Use of Preprint in the Publication of the Scientific Papers
Authors: Rustan E 
Published: February 2021

Abstract
The publication is an important stage in a study. However, the publication stage in an accredited journal must go through a peer-reviewed process and sometimes requires a fee. The preprint server is a media archive for the distribution and distribution of articles that are available free of charge, enabling rapid distribution and use. Currently, there are many preprint servers available which are also recognized by peer-reviewed journals such as Arvix, Academia, Researchgate, OSF and in Indonesia itself there are INA-Rxiv servers. This article aims to explain the use of the preprint server as a publication media for scientific work among academics. The research method used is survey research on all academics in Indonesia. The results of the study showed that 42% of academics did not recognize the preprint server, 58% did not understand the function of the preprint server as a media publication that was fast, extensive, minimal in cost, accessible to the whole world and had DOI. They think the articles that have been published in the preprint can no longer be proposed to be published to an accredited journal. Ignorance causes its user to be very minimal, with only 24% of all academics filling out the questionnaire. The majority prefer to look directly for accredited journals without considering the time and cost required until the article is published.

Authors: Marwati A M , Mas’ud B 
Published: February 2021

Abstract
The mathematical ability and mathematical problem solving skill can be separated in learning mathematics. In the fourth industrial revolution, one of learning objectives of learning mathematics is the student has a skill in solving mathematical problem. Meanwhile, mathematical problem solving skill can be obtained if the students’ mathematical concept understanding is high including multiplication and division of fractions. They stated that understanding fraction concept was very difficult. This study aimed to analyze the student mathematical problem solving skill of the tenth grade of Junior High School in completing multiplication and division of fractions. This research had 8 informants. Data was collected using interview and test and applied qualitative and quantitative analysis. The initial data was obtained from elementary school with three categories of mathematical ability level, namely (1) one student had high skill, two students had moderate skill and one student had low skill. The indicator of mathematical problem solving was based on George Polya (1983) consisting of four steps, they are (1) understanding problem, (2) planning a problem, (3) completing the problem, and (4) rechecking the result. The research result indicated that the student mathematical problem student was low, especially the problem solving of fraction division and multiplication. The student was difficult to make a solving plan. This situation effected on problem solving caused by the indistinctness of problem solving plan or mathematical model and/or mathematical formula about verbal sentence of mathematical problem solving. The result of interview described that the teacher did not explain the ways of completing mathematical problem solving based on G.Polya’s steps. In addition, the students were less practice in completing the problem solving questions. Besides, the teacher did not integrate the objectives of basic competence 3 and 4 in each meeting.

Abstract
Mangroves play an important role in coastal community livelihoods of South Sulawesi. However, due to excessive and unsustainable use, mangroves experience degradation and deforestation in the past two decades. This study aims to detect mangrove extents, densities, and distributions changes during the periods 1997, 2007, and 2018 in Pannikiang Island, Barru Regency. We used three Landsat satellite imageries with acquisition 1997, 2007, and 2018 and implemented the multispectral classification and NDVI transformation methods, and the results were tested by ground truth. The results showed mangrove extents in 1997, 2007, and 2018 were 94.83 ha, 92.07 ha, and 91.64 ha, respectively. During these periods, mangroves decrease by 3.19 ha or an annual average of 0.15 ha. The decrease is caused by the expansion of settlements and aquaculture ponds. In 1997, the mangroves high-density class about 61.74 ha, moderate-density 14.19 ha, and low-density of 18.6 ha. In 2007, the high and low-density classes decreased to 54.53 ha and 12.29 ha, while the moderate-density increase to 25.35 ha. Finally, in 2018, the high-density class continues to decline by 43.36 ha, while for the low and moderate classes increases 15.34 ha and 32.67 ha, respectively, compared to the previous decade.

Published: February 2021

Abstract
A microphysiological system (MPS) holds great promise for drug screening and toxicological testing as an alternative to animal models. However, this platform faces several challenges in terms of the materials used (e.g. polydimethylsiloxane; PDMS). For instance, absorption of drug candidates and fluorescent dyes into PDMS, as well as the effect elicited by materials on cultured cells, can cause inaccurate or misleading results in cell assays. The use of PDMS also poses challenges for mass production and long-term storage of fabricated MPSs. Hence, to circumvent these issues, herein we describe the development of a cyclo olefin polymer (COP)-based MPS using photobonding processes and vacuum ultraviolet (VUV), designated as COP-VUV-MPS. COP is an amorphous polymer with chemical/physical stability, high purity and optical clarity. Due to the thermostability and high modulus of COP, the metal molding processes was applied for mass production of MPSs without deformation of microstructures and with quick fabrication cycle time (approx. 10 min/cycle). Moreover, VUV photobonding process with an excimer light at a 172nm wavelength allowed assembling COP materials without the use of additional solvents and tapes, which might cause cell damages. In comparison with the conventional MPS made of PDMS (PDMS-MPS), COP-VUV-MPS showed improved chemical resistance without causing molecule absorption. Moreover, COP-VUV-MPS maintained the stemness of environmentally sensitive human-induced pluripotent stem cells without causing undesired cellular phenotypes or gene expression. These results suggest that COP-VUV-MPS may be broadly applicable for the advancement of MPS and applications in drug development, as well as in vitro toxicological testing.

Published: February 2021

Abstract
Closed nuclear fuel cycle is one of the most promising options for the efficient use of nuclear energy resources with full recycling of long-lived transuranic elements. However, it can be implemented only in fast breeder reactors of Generation IV. The paper shows our methodology applied in the analysis of the lead-cooled fast reactor equilibrium fuel cycle using the Continuous Energy Monte Carlo Burnup Code – MCB. The implementation of novel modules for nuclear transmutation trajectory folding allows us to trace the life cycle of crucial minor actinides from the beginning of the reactor’s life towards the state of adiabatic equilibrium. Changes in the mass contribution to gateway isotopes 242Pu, 243Am and 244Cm during 124.2 years were considered in the study. Numerical demonstration was performed for the reactor core designed within the European Lead-cooled System (ELSY) project and redefined in the follow-up Lead-cooled European Advanced Demonstration Reactor (LEADER) project.

Abstract
Solar energy is one of the fastest growing energy industries around the world. One of the main problems faced by PV installations is the diversity of solar energy supply during the day. To increase the efficiency of providing this energy, use solar tracking - A solar tracking system is a specific device intended to move the PV modules in such a way that they continuously face the sun with the aim of maximizing the irradiation received by the PV array. The use of such a solution always increases efficiency, regardless of location. This is crucial in the case of India, which increased its energy production from solar panels by 8 times in 4 years. In this article we present the results of joint work of students from Poland and India. Based on the work, they designed and constructed a solar tracking system based uniquely on image processing. Instead of the most common photoresistors, to determine the position of the sun in the sky, the image from the camera was used, which was then subjected to appropriate filtration to quickly and efficiently determine the brightest point of the image - assuming that this is the position of the sun. Then, based on the coordinates of the brightest point, servo motors position the panel at the right angle, perpendicular to the sun, on the vertical and horizontal axis. The control unit is Raspberry Pi Zero, to which both the servos and the camera are connected. Research in laboratory conditions, under artificial light, confirmed the correct operation of the system. The system should be able to follow the sun also under various weather conditions which are occurring in Nagpur where system is located. It can be used in practical application and operate in real time.
