Abstract

Empirically, societies have utilized neem plant to treat worm infection, scabies, malaria, candidal infection, and allergy. Several researches have indicated that consuming neem leaves could improve antibody production. Our previous research had demonstrated the existence of immunomodulatory component in neem leaves weighted 70 and 100 kDA. The aimed of study was to test the activity immunomodulatory components to Candida albicans. This research was an in vitro study with rats as experimental subject. The rats were divided into three treatment groups and one control group, which were labeled as KO (no treatment), KP1 (inoculated by C. albicans only), KP2 (inoculated by C. albicans and were given the 70 kDA immunomodulatory component), KP3 (inoculated by C. albicans and were given the 100 kDA immunomodulatory component). In day 21, preparations from rats’ tongue were done with immunohistochemistry staining and were analyzed for the activity of TNF-α macrophage phagocytosis and also for calculation of C. albicans colony from tongue swab. The result showed that there was no significant difference between the 70 and 100 kDA immunomodulatory components in increasing activity of TNF-α and macrophage phagocytosis and in decreasing the number of C. albicans colony. It was assumed that those components might actívate NF-κB and AP-1 that play role in protein transcription, which stimulated gene expression like TNF-α, which played role in phagocytosis. In conclusión, 70 dan 100 kDA immunomodulatory components increased the activity of TNF-α and macrophage phagocytosis and also decrease the number of C. albicans colony.

Abstract

Based on the Global Competitive Report of 2014 - 2015, ranking the competitiveness of Indonesia to review the Year 2014 - 2015 from 144 countries in the World, Indonesia ranks to 34; among Asean Countries and still under country of Singapore, Malaysia, Brunei Darussalam and Thailand. One cause is the selling price less competitive, against the background cost of goods sold improper, mainly include overhead still using the calculation system / the traditional method; which will impact the determination of the cost per unit distortion product so unreliable measure efficiency and productivity. Determining the cost per unit more accurate as essentials management to review the basic fundamentals of decision making, for example, adopting with ABC formula. Efforts reaching competitive excellence, as well as eliminating non-value added activities, it's time for a company in Indonesia to re-design of cost system.

Abstract

This study aims to describe the effectiveness of online Indonesian language (Bahasa Indonesia) learning that improves students’ language skills in the cognitive domain. The research method used was descriptive qualitative. The data were in the form of teacher and student reports about the learning process and documentation. Data collection techniques were done by observation, interview and questionnaire. The data analysis technique used interactivity. The results of the study were distinguished by three findings, namely the online learning process, learning obstacles and learning achievement based on the Minimum Completeness Criteria (KKM) obtained by students in the cognitive domain. Learning during the Cocid-19 pandemic takes place online. Obstacles had been found in learning, especially those faced by students. Learning Indonesian online by improving language skills in the cognitive aspect was effective. This was indicated by the achievement of students’ scores higher or above the average of the KKM (> 80).

Abstract

Background. Student reasoning in learning mathematics contributes significantly to the achievement of student mathematics learning outcomes. The main objective of this study is to investigate the process of reversible reasoning in students for inverse problems, in the case of Adjie (Ad). The research method used to reveal the reversible reasoning in Adjie's case using descriptive qualitative research methods. Sampling was carried out using purposive sampling technique where the research sample was selected based on reversible reasoning criteria. Retrieval research data uses the results of students' mathematical work, think aloud, interviews, and the components that cause reversible reasoning. The results of our study found that the process begins with an obstacle that causes Ad to be unable to continue the resolution process, resulting in a metacognition process by analyzing the problem again analytically and developing other heuristic strategies. Ad shows a change in perspective where he initially interpreted inverse as the act of swapping independent and dependent variables and switched to interpreting inverse as the opposite of a function process involving analogy and image representation. The contribution of this research provides knowledge that reversible reasoning can occur in understanding and solving mathematical problems in inverse material.

Abstract

Belanja perpajakan menyebabkan berkurangnya penerimaan pajak dari wajib pajak tertentu. Tujuan dari ketentuan belanja perpajakan adalah untuk mencapai tujuan sosial dan tujuan ekonomi. Hal ini telah menarik banyak cendekia untuk melakukan studi terkait belanja perpajakan. Pada penelitian ini, analisis bibliometrik dilakukan atas artikel penelitian yang dipublikasikan di jurnal yang terindeks Scopus selama tahun 2001 – 2021 (periode 20 tahun). Penelusuran artikel menggunakan aplikasi Publish or Perish. Hasil penelusuran diseleksi menggunakan aplikasi Mendeley dan diperoleh 52 artikel. Selanjutnya, artikel terpilih dianalisis dengan aplikasi VOSviewer. Hasil analisis menunjukkan 52 artikel tersebut dapat dikelompokkan menjadi empat klaster. Keempat klister tersebut mewakili empat arus penelitian belanja perpajakan.

Abstract

Soybean shell waste contains organic material with pH levels classified as acidic which can endanger environmental sustainability and pollute water and soil. This research raises the issue of utilizing soybean shell waste into more useful products. Soybean shell waste is used as new materials in the form of composites to be used as products that have economic value and overcome negative environmental impacts. The composite results in this study in this study were in the form of soybean skin bio leather sheets which were then analyzed for raw material talent to determine the potential of soybean skin bio leather sheets to be used as alternative product design materials. The actions taken to identify the talent of the sheet are by exploring and testing the translucency of the light to determine the distribution of the light produced, testing the sustainable sheet with the process of soaking the soil and water, and giving color. After analyzing material talent, in product design using the MACAK design method in the design so that product recommendations are found using soybean skin bio leather material. One of the product recommendations that can be developed is the design of a decorative lampshade with a Scandinavian concept with a weaving technique with a zig zag motif and geometry for hanging wall lamps, and table lamps using soybean skin bio leather.
