But it contributes to generating a large amount of total dissolved solids (TDS) and increasing the salinity of water during leather processing which is a threat to the environment. The current research is an attempt to preserve goat skin using mahogany (Swietenia mahogany) seed’s extract. In real practice different percentages of mahogany seed extract were applied on raw goat skin and 3% (by weight of skin) of it showed best result. To evaluate the preservation efficiency, related parameters of preservation viz. odor, hair slip, shrinkage temperature, moisture content, bacterial count etc. were monitored regularly for 30 days. The obtained results were compared with conventional salt curing process. The experimental trial showed efficiency in lessening TDS value and chloride content. The preserved goat skins of both trials were treated following conventional leath...

A huge amount of basic chromium sulfate (BCS) is used in leather tanning. About 60–70% of BCS has been taken by leather and the rest of the amount is discharged as effluent and solid waste. In the Common Effluent Treatment Plant (CETP) of BSCIC Tannery Industrial Estate (Hemayetpur, Savar, Dhaka), the effluent which contained a high concentration of chromium is precipitated as solid chromium hydroxide with other elements which is called a chrome cake. Chrome cake is not exposed directly in the open space due to its toxic effect on human health as well as the environment. Human occupational experience distinctly indicates that, when inhaled, chromium compounds are respiratory tract irritants, resulting in airway irritation, airway obstruction, and lung, nasal, or sinus cancer. It is strongly suggested to extract Cr from the chrome cake before dumping it; otherwise, it will be a potential hazard to the environment. Herein, the chrome c...

Recent trend of tanning is thus heading to chrome-free and greener chemical processing options. Vegetable tanning is an exoteric leather processing technique because of their lower pollution load on the environment. Considering the inadequacy and high costing for the commercialized tannins, development of alternative tannins from locally available plants and their characterizations are important. In this research, the stem barks of Trema Orientalis (L.) were extracted at different temperatures employing water solvent with or without additives (sodium hydroxide or sodium sulphite) to attain phenolic-rich extractives. To ascertain appropriateness as a vegetable tanning agent, the obtained extracts were thereafter characterized in respect to yield, total phenolic content, tannin content and molecular structur...

Both etymologically,epistemology, historical and applicative methods as interpretations of the al-Qur’an.Ta'wil is the most important part in understanding the Qur'an, while hermeneutics is a tool to interpret and understand the bible. By prioritizing hermeneutics in the interpretation of the al-Qur’an is not able to reach what is revealed by Allah in the Qur'an. Because hermeneutics is not a perfect method applicable if forced to the Qur'an that the original source of Allah SWT, with a language so have a high level of literary taste. Match between ta'wil and hermeneutics is not appropriate, because both come from different sources. And is ultimately resulting in the quality of the interpretation is different

These two major groups of countries that are often opposed, including in terms of the economic system implemented in both groups of countries. Since it is argued that Islamic nations apply a specific system of financial in the economy, namely the Islamic financial system, hence this research investigated the effect of both group nations (Islamic or non-Islamic) comparatively to the economy. The research method used in this research is quantitative approach by using statistical analysis, multiple linear regression, as the method of data analysis, in order to obtain results that can be drawn conclusions as a result in this study. Based on the findings, it can be concluded that education has a positive and significant impact to the economy, as an input of civilization, although there are no different econ...

However, the enrichment of the environment and the way of learning is difficult for the santri-santri mubtadi ', thus causing their mind and soul to feel uneasy. This activity is held every Friday night and is very instrumental in Psychological Well Being (peace of soul) santri. Because this activity contains about the glory and majesty of Prophet Muhammad SAW, which if read will give peace to the listener without him have to understand the meaning. The formulation of the problem in this research is: how the role of boarding school Sabilul Hasanah in building Psychological Well Being santri Mubtadi 'through reading shalawat Mahalul Qiyam method? Data analysis techniques used are qualitative data analysis techniques. The method used is Sampling Technique Method, data collection techniques used are Observation, Interview, and Documentation techniques. From the results of the research obtained from the interviews and observations are: that the activity of shalawat in the mawlid Simtudduror is very instrumental to Psychological Well Being (peace of soul) students Mubtadi 'in raising the love of the Prophet Muhammad SAW, understand the beauty of life with the affection of his parents, and also in the process of self-adaptation to the new environment he first undergo

This study was an endeavor to introduce a convenient natural dye from the insect of Cocus Lacca for dyeing leather in an eco-friendly way. The effect of process parameters of dyeing viz. pH, temperature, time duration, exhaustion of color, shade brightness, color fastness etc. had been studied. Result showed that the optimum extraction was 4% at 90°C. The pH of the developed dye was 6.5 and optimum time of dye exhaustion was 80 minutes. The extracted dye was applied on split leather with and without mordant. It was found that mordant has a significant effect on the color of leather. Ferrous Sulfate (FeSO4) mordant showed more excellence. Future research on the same field using different extraction methods, different mordants, and mordanting methods will optimize the results of the current study.

The research conducted in Kampung 10 Ulu has three distinctive ethnicities, namely, Malay, Chinese and Arab. Even in the presence of ethnic differences, religious, social and economic life goes well and there are no problems or conflicts that exists in the Kampung 10 Ulu society. Each of the ethnics are able to carry out their activities without pressure and coercion since the beginning of time. Malays are able to accept Chinese and Arab cultures and the presence of sanjo culture, leading to the intermingling and interactions within the societies, thus creating high tolerance and strong community ties within Kampung 10 Ulu. This research examined the extent of cultural influences on the religious, social and economic life and what are the impacts of the cultural influences have on these scopes of life to the people of Palembang.

The IR 4.0 has changed the technological innovation environment in which it is controlled by artificial intelligence and digital physical frameworks which make interface between humans and machines more universal. Innovation’s rapid revolution has provided another education model for the future (Education 4.0). In order to prepare graduates for future life and work accomplished through IR 4.0 where more smart robots will replace people in certain divisions of service or jobs, education should leverage relevant information and expertise that could not be replaced by robots. Innovation interruption that creates Education 4.0 based on educational growth and skills has made future learning more custom, hyper, smarter, flexible, worldwide and interactive. As cutting edge educators, to improve future learning, we need to explore new and creative approaches to using educational creativity. In this regard, this introduction hypothesizes the necessity that teachers re-examine their old teaching and learning originations, and update or upgrade the learning experiences of their understudies so that they meet the requirements of Education 4.0.

Smartphones are equipped with features such as Internet access, cameras (pictures and videos) and MP3 players. While a majority of previous research investigated the use and effects of mobile phones and young people, these studies focused on the Western context. A qualitative research method was used to investigate the research questions. Specifically, focus groups and in-depth interviews were used to collect data. Nevertheless, while a growing number of studies has investigated mobile phone use by teenagers in non-western countries, there is little research on smartphone uses and their implications to teenagers in an Islamic context. This article examines the uses of smartphones by, and their implications to, Bruneian teenagers. The research seeks to map and understand the complex forces that influence and challenge the socio-cultural values and religious beliefs of teenagers in a non-Weste...
