The study aims to know and analyze the effect of motivation, work discipline, and compensation on employee performance both partially and simultaneously. This research was carried out at PT. Sinar Jernih Suksesindo. The procedure starts from the trial of research instruments, data collection through questionnaires, conducting data analysis, and preparing research report results. The number of samples studied amounted to 130 employees. The data used in this study is the primary data that researchers obtain directly from the source. The result of this study states motivation, leadership and Compensation has significant effect on the employee performance with a sig value < 0.001. Factors that affect performance include work discipline, compensation, and motivation. Work discipline is needed to produce a good performance; with discipline, employees will try to do the work as much as possible, and the resulting performance will be better. Discipline must be enforced in an organization or company because without good employee discipline, and it is difficult for companies to realize their goals. The key to the company's success in achieving its goals is discipline. A discipline is a form of awareness or willingness of a person to obey all organizational or company regulations and applicable social norms.
This study investigated the effects of a small group process-based forgiveness intervention with Hong Kong Chinese children who judged themselves to have been hurt and chose not to forgive their offenders. An experimental versus control group, with pre-test/post-test design was used. The quantitative and qualitative findings revealed that the forgiveness participants out-performed their counterparts in forgiveness attitudes, psychological well-being and conceptual understanding of forgiveness. The forgiveness intervention had an impact on their decision and emotion to forgive. Empathy was considered a key strategy in forgiveness. Implications of these findings for future forgiveness intervention in school guidance were discussed.
Purpose Motivated by legitimacy theory, this paper aims to examine comprehensively corporate social responsibility (CSR) disclosure in Southeast Asian (Association of Southeast Asian Nations [ASEAN]) countries with the aim of disentangling whether such disclosures are the result of a proactive stance or a reaction to regulations. Design/methodology/approach After a content analysis of CSR stand-alone reports that relies on the Global Reporting Initiative as the basis for comparison, a multivariate analysis is carried out while controlling for firm-specific incentives and industry, country and year fixed effects. Findings The paper finds that CSR disclosure increased across the entire ASEAN. Although this increase cannot be directly ascribed to the introduction of regulations in Indonesia and Malaysia, the latter may have impacted choices of disclosure media. In countries where reporting requirements have become mandated, mandatory reporters show low levels, and voluntary reporters high levels, of CSR disclosure. The paper also finds that the attainment of CSR awards is related to disclosure. Additional analyses reveal a substitution effect between voluntary and mandatory incentives in countries with high levels of law enforcement. Practical implications The evidence suggests that the introduction of regulations can be effective in improving the level and breadth of CSR reporting only in the presence of institutions that ensure the enforcement of the disclosure regulations. Social implications The evidence suggests that organizations are reluctant to report on issues such as child labor, human rights and corruption. Organizations opportunistically employ related disclosure strategies that deviate from the underlying CSR performance. Originality/value The paper analyzes not only the level and breadth of CSR disclosure but also the motivation for its use across the still under-investigated ASEAN area, thus allowing an examination of the influence of institutional incentives above and beyond the firm-specific factors that drive CSR activities.

Abstract Nowadays, water pollution is a major concern to the globe. For this reason, various research works has been done to access pure water thereby minimizing the effect of pollutants. In this work, the cobalt doped ZnO (Co-doped ZnO) via the accumulation of cobalt ion onto Eichhornia crassipes plant tissue for different days and combined with zinc precursor was synthesized. The resulting catalyst powder samples were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), X-Ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FE-SEM), and Ultraviolet–vis (UV–vis) spectroscopy, and microwave plasma atomic emission spectrometer (MP-AES). The catalysts were also tested for the photocatalytic degradation of methylene blue (MB) in the presence of H 2 O 2 under visible light irradiation. The best catalytic activity was gained by the 8th-days accumulation of cobalt ion onto the Eichhornia crassipes plant tissue and 99.6% of the dye was degraded within 45 min. However, 69.6, 65.7, 73.6, and 94.8% of MB dye was degraded by 1, 2, 4, and 6 days accumulations. Hence, removal of toxic heavy metal by using Eichhornia crassipes plant and recycling in the wastewater treatment gain is highly appreciated. Moreover, the Co-doped ZnO photocatalysts could enhance the photocatalytic activities due to suppressing of the electron and hole recombination and the porosity of the catalysts resulted from the Eichhornia crassipes plant after calcination.

BACKGROUND: Skin aging is the most common dermatological problem caused by intrinsic and extrinsic factor, such as exposure to (ultraviolet) UV rays. Chlorogenic acid (CA) is a phenolic compound which is known for its antioxidant properties against oxidative stress. OBJECTIVE: This study investigates the antiaging and anti-inflammatory properties of CA on UV-induced skin fibroblast cells. METHODS: Anti-inflammatory properties of CA were assessed by measuring inflammatory-related proteins IL-1β and TNF-α, while antiaging properties of CA were assessed by measuring reactive oxygen species (ROS), apoptosis, live and necrotic cells, and COL-3 gene expression level. RESULTS: Treating UV-induced skin fibroblast cells with CA decreased the level of ROS, IL-1β, TNF-α, apoptotic cells, and necrotic cells and increased live cells and COL-3 gene expression. CONCLUSION: CA has the potential as the protective compound against inflammation and aging by decreasing the level ROS, pro-inflammatory cytokines IL-1β and TNF-α, apoptotic cells, and necrotic cells and by increasing live cells and COL-3 gene expression.

Aging is a complicated process occurring due to the combination of incremental alterations of the skin and accumulated extrinsic factors that causes both structural and functional disruptions. The extrinsic factor of skin aging is mostly caused by free radicals, UV exposures, and pollution. Prevention is possible by escalating antioxidant intake to scavenge ROS in the skin aging process. Rutin and caffeic acid are recognized for their free radical trapping effects and reported to have potential antiaging activities. This study aimed to identify the potentials of rutin and caffeic acid as antioxidant and antiaging. Rutin and caffeic acid were tested for their antioxidant properties using the DPPH, H 2 O 2 , ABTS radical scavenging, and FRAP assays. Meanwhile, their antiaging activities were examined by collagenase, elastase, hyaluronidase, and tyrosinase inhibitory assays. The study drew on the evidence of antioxidant and antiaging properties from the scavenging, ferric ion reducing, and inhibitory activities of rutin and caffeic acid (in ascending order): in scavenging DPPH free radicals (IC 50 of rutin = 5.79 µg/mL, IC 50 of caffeic acid = 8.72 µg/mL), scavenging H 2 O 2 ( IC 50 rutin = 12.09 µg/ml, IC 50 caffeic acid = 15.23 µg/mL), reducing ABTS (IC 50 caffeic acid = 6.23 µg/mL, IC 50 rutin = 16.59 µg/mL), reducing ferric ions at 50 µg/mL (FRAP of rutin = 480.08 µM Fe(II)/µg, FRAP of caffeic acid= 526.50 µM Fe(II)/µg), inhibiting collagenase (IC 50 caffeic acid = 74.42 µg/mL, IC 50 rutin = 104.70 µg/mL), inhibiting elastase (IC 50 rutin = 46.88 µg/mL, IC 50 caffeic acid = 76.95 µg/mL), inhibiting tyrosinase (IC 50 rutin = 55.65 µg/mL, IC 50 caffeic acid = 145.91 µg/mL), and inhibiting hyaluronidase (IC 50 rutin = 114.07 µg/mL, IC 50 caffeic acid= 244.45 µg/mL). Rutin and caffeic acid have the potentials as antiaging and antioxidant.
Genetic algorithms can solve complex problems, including the problems of cryptography.What problems often occur on the Hill Cipher is the waste of time to determine the numbers that are used in the encryption process.In the encryption process, it is not a problem if the key is derived from any number.However, the problem is ciphertext cannot be returned to the original message.The key that is used must have the determinant is 1.To find the value of it is something that takes time if it must be done manually.Due to the entered value to the Hill Cipher is random, Genetic algorithms can be used to optimize the search time.By using this algorithm, the determinant calculation will be more accurate and faster.The result achieved is the program can specify some combination of numbers that can be used as the encryption key Hill Cipher and it can reject the unnecessary numbers.
Nowadays, the ICT is an important part of the 21st century and teacher learning and industry 4.0 challenges must involve technology in their teaching and learning. Previous research on the involvement of technology in the learning process is generally known as TPACK, Technology – Pedagogy – Content - Knowledge. However, the specific objectives of implementing vocational learning are specific to certain occupations. The purpose of this study is to analyse the teaching and learning needs of students in professional vocational education with the revised TPACK new model approach. The study of qualitative methods in the form of document analysis is used to construct a new theoretical conceptual framework. Important findings offered in the concepts of teaching and learning of vocational students were adopted based on work, content, technology, and learning approaches which were conceptualized as TAWOCK.The work as a new domain shows the characteristics of student teaching and learning while the learning approach has shifted from the level of engagement - Pedagogy to the level of cultivation - Andragogy. The study explains that vocational education with the TAWOCK concept is an ideal model for developing depth.

BACKGROUND: Ruiz and Pav) is one of Indonesia's medicinal plants that has been known to exhibit antioxidant, anti-inflammatory activities. This study aims to determine hepatoprotective effect of red betel leaves extract (RBLE) towards liver injury. METHOD: -induced HepG2 cells were treated with 25 µg/mL and 100 µg/mL RBLE. Several parameters were observed, including TNF-α level through ELISA; necrotic, apoptotic, dead, live cells; and ROS level through flow cytometry analysis; and GPX gene expression through qPCR. RESULT: The study showed that treatment with RBLE were able to decrease TNF-α level; necrotic and death cells percentage; as well as ROS level. On the other hand, it were able to increase apoptotic and live cells percentage; as well as GPX gene expression. Low concentration (25 µg/mL) of RBLE treatment exhibited stronger anti-inflammatory activity as it was resulted in the lower TNF-α level and were able to switched hepatic cell death pathway from necrosis to apoptosis as shown by the shifted of apoptotic cells and necrotic cells percentage. This lead to lower death cells and ultimately improve live cells percentage. Meanwhile high concentration of RBLE (100 µg/mL) exhibited stronger antioxidant properties as indicated by lower ROS level and higher GPX gene expression. CONCLUSION: Overall, this study was able to demonstrate hepatoprotective effect of RBLE towards liver injury model through its anti-inflammatory and antioxidant activities.
