Abstract

In Indonesia, the high number of breast cancer cases is not always followed by complete clinical and histopathological determination, even though clinical and histopathological staging is needed to determine the diagnosis and further management. Breast cancer is a malignant mass originates from the uncontrolled division of cells in breast tissue Breast cancer or mammary carcinoma is a lump that grows and develops abnormally in the cells and tissues located in the breast, such as the fat tissue and connective tissue in the breast, ducts and lobules. The histopathological examination procedure is that the patient must undergo a biopsy. Biopsy results can be used to diagnose breast cancer and also monitor the success of therapy. Mammary carcinoma can spread to surrounding tissue or to other organs through blood vessels. Breast cancer is the most common cancer in Indonesia. The prognosis of breast cancer is determined by the 5 years survival rate. The survival rate for cancer sufferers in Indonesia is low compared to other developing countries, namely 51.07%. This research is in the form of a literature review with 14 papers as references. The results obtained were that invasive ductal carcinoma was the most common mammary carcinoma and grade II-III was found to be the dominant grade.

Abstract

Onventional teaching media used by teachers in teaching chemical bonding has not been able to facilitate students in understanding the concept of chemical bonding because the media used are still in two-dimensional form. Therefore, it is necessary to develop three-dimensional teaching media capable of visualizing the concept of chemical bonding, one of which is augmented reality (AR). This study aims to determine the validity and practicality of an AR-based chemical bonding module. The research type used is Borg and Gall's development research model, modified into 7 research stages. The research sample consisted of 30 students selected using purposive sampling technique. The results of material, media, and language validation analysis indicate that the developed AR-based module is valid with validity percentages of 96.66%, 81.47%, and 88.33%, respectively. Practicality analysis using a practicality questionnaire shows that the developed AR-based module is practical with a practicality score of 93.88%. Therefore, the AR-based module is highly suitable as an alternative teaching media for the topic of chemical bonding

Abstract

This study aims to analyse the potential energy that can be generated from municipal solid waste (MSW) at Tamangapa landfill, check the adequacy of energy according to the target of 20 MW/day, and give consideration to WtE technologies that can be applied. The research began with a literature study, followed by a quantitative approach to calculate the potential energy that can be generated through incineration, gasification, pyrolysis, anaerobic digestion (AD) and fermentation WtE technologies. The results showed that the energy target of 20 MW/day from MSW in Makassar can be met through incineration (168.80 MW/day), gasification (28.29 MW/day) and pyrolysis (62.03 MW/day). However, if 20 MW/day is clean energy, then considering the energy conversion efficiency, 30.38 MW/day is obtained for incineration, 7.07 MW/day for gasification, and 15.51 MW/day for pyrolysis. Based on this calculation, only incineration technology can fulfil the 20 MW/day energy target as expected. In order to maximise the energy potential, it is recommended to use a combination of incineration WTE technologies for plastic, rubber, paper and fabric components, and pyrolysis for wood and food waste components.
