The Meaning of The Hajj Ritual: William R. Roff Thoughts and His Contribution to Islamic Studies in Indonesia
Full text linkThis article aims to analyze William R. Roff’s theoretical approach to Hajj and its contribution to Islamic studies in Indonesia. This contribution arose from his concern with the very few historians of religions who made functional, analytical categories for explaining religious phenomena. This paper is a literature study and uses William R. Roff’s writing, Theoretical Approaches to the Hajj, as the primary source and analyzes it using qualitative data analysis. The author found that William R. Roff explained the implementation of the pilgrimage and its meaning by elaborating on Arnold van Gennep’s theory and Victor Turner’s thesis. The pre-implementation stage of the pilgrimage means the separation contained in the ramalan ritual (extra-Islamic) to determine the best time for the pilgrims’ departure, apologies and prayers, preparation of supplies, repayment of debts, and their obligations before the pilgrimage. The stage of the hajj implementation means the transition that is contained in the peak performance of the hajj ritual. The post-implementation phase of the Hajj means togetherness in the change in attributes, understanding of the pilgrims, and their implementation in the community life where they live. William R. Roff’s theoretical contribution to the pilgrimage, the outcome of which was satisfactory to both parties, has been used as a model by scholars and researchers for studying other religious rituals in Islam. His interpretation of the hajj ritual falls into the third phase called new Islamic studies to approach

Investigation of mechanical properties of recycled polypropylene
Full text linkEvery year there is an Increase in the amount of plastics formed by all types of processes, such as extrusion, blow moulding, injection moulding, etc The recycling of waste plastic materials 1s developing at a manufacturing process scale, and rts arm is to increase further the sales o f plastrc products by reducing raw material costs However thrs economic argtunent rs only one of the reasons why it is important to recycle these materials. The other is environmental.
Each time an item of plastic material passes through the manufacturing process, its quality is reduced. Some plastic material can be recycled over and over again. This research concerns the number of times polypropylene (PP) formed by the injection mouldlng process can be recycled. The work focuses on the quality of the materlal dter each recycling operation Material was passed through the forming process up to three times Also, since it is posslble to improve the quallty and reliability of the polypropylene, by addlng a percentage of fresh "raw" rnatenal, the study included an rnvest~gatront o optirnlse the mechanical properties using this approach.
The moulding process was used to produce products whose mechanical properties could be measured to provide an indication of the quality of the material at that stage. The relationship between the mouldlng process parameters and the qualify of the subsequent products was analysed, and thls was extended for cases where the materlal was recycled twlce or three times through the equipment The powders ploduced m these trlals were then mixed with diffelent percentages of raw material, and passed through the equrpment again to produce products whose mechanical propert~esc ould be measured.
To reduce the number of permutations a Design of Experiments (DOE) method was implemented to define the moulding process conditions whlch resulted In the optimum product quality for material belng recycled once, twice or three tlmes. A 2 Factorla1 Design (FD) techque was also used. Different mathematical models were obtained to show the relationship between the process parameters, the number of times the material was recycled, and the product quality Thls was extended to show the effect of adding a percentage of raw material to the powder mix.
All the mathematical models were verified by further experimentation The resuIts show that these models can predict the mechanical properties of the products adequately, once the processing parameters have been defined
PENGARUH VARIASI BAHAN BAKAR VIVO DAN SHELL DENGAN OKTAN 92 DAN 95 TERHADAP PERFORMA SEPEDA MOTOR YAMAHA MIO 150 CC
No full textCurrently, public vehicles such as motorbikes use several types of fuel, including fuel from Vivo and Shell companies apart from Pertamina. Motorcycle engine performance is influenced by several factors, including the type of fuel used. Many people do not know the effect of using this fuel (Vivo and Shell) which has RON 92 and RON 95 on the engine itself due to a lack of understanding of the properties of the fuel. Therefore, the author intends to conduct research on the analysis of the influence of RON 92 and RON 95 fuel from Vivo and Shell products on the performance of the Yamaha Mio 150 cc reciprocating engine in order to obtain optimum fuel. This research aims to determine the difference in motor performance when using Vivo and Shell fuel by testing torque, power, and then analyzing specific fuel consumption. The tests for each type of fuel were Revvo 92, Revvo 95, Shell Power 92 and Shell V-Power 95 which were tested on a 150 cc Yamaha Mio motorbike engin

Political Instrumentalisation of Islam, Persistent Autocracies, and Obscurantist Deadlock
Full text linkThe empirical literature has established a strong link between the fact of being a Muslim-dominated country and indicators of political performance and democracy. This suggests the possible existence of a relation between religion, Islam in this instance, and societal characteristics. Bernard Lewis and others have actually argued the case for such a relation, pointing to aspects of the Islamic religion and culture that make the advent of democracy especially difficult. These arguments fall into the general idea of the Clash of civilisations put forward by Samuel Huntington. In this paper, we discuss this sort of argument and show that there is a systematic misconception about the true nature of the relationship between Islam and politics: far from being merged into the religious realm, politics tends to dominate religion. Because of the particular characteristics of Is-lam, namely, the lack of a centralised religious authority structure and the great variability of interpretations of the Islamic law, there is a risk of an obscurantist deadlock in the form of a vicious process whereby both the ruler and his political opponents try to outbid each other by using the religious idiom. This risk looms particularly large in crisis situations accentuated by international factors.
Molecular biology of hearing
No full textThe inner ear is our most sensitive sensory organ and can be subdivided into three functional units: organ of Corti, stria vascularis and spiral ganglion. The appropriate stimulus for the organ of hearing is sound, which travels through the external auditory canal to the middle ear where it is transmitted to the inner ear. The inner ear houses the hair cells, the sensory cells of hearing. The inner hair cells are capable of mechanotransduction, the transformation of mechanical force into an electrical signal, which is the basic principle of hearing. The stria vascularis generates the endocochlear potential and maintains the ionic homeostasis of the endolymph. The dendrites of the spiral ganglion form synaptic contacts with the hair cells. The spiral ganglion is composed of neurons that transmit the electrical signals from the cochlea to the central nervous system. In recent years there has been significant progress in research on the molecular basis of hearing. An increasing number of genes and proteins related to hearing are being identified and characterized. The growing knowledge of these genes contributes not only to greater appreciation of the mechanism of hearing but also to a deeper understanding of the molecular basis of hereditary hearing loss. This basic research is a prerequisite for the development of molecular diagnostics and novel therapies for hearing loss
The Global Retinoblastoma Outcome Study: a prospective, cluster-based analysis of 4064 patients from 149 countries
Full text linkBackground: Retinoblastoma is the most common intraocular cancer worldwide. There is some evidence to suggest that major differences exist in treatment outcomes for children with retinoblastoma from different regions, but these differences have not been assessed on a global scale. We aimed to report 3-year outcomes for children with retinoblastoma globally and to investigate factors associated with survival. Methods: We did a prospective cluster-based analysis of treatment-naive patients with retinoblastoma who were diagnosed between Jan 1, 2017, and Dec 31, 2017, then treated and followed up for 3 years. Patients were recruited from 260 specialised treatment centres worldwide. Data were obtained from participating centres on primary and additional treatments, duration of follow-up, metastasis, eye globe salvage, and survival outcome. We analysed time to death and time to enucleation with Cox regression models. Findings: The cohort included 4064 children from 149 countries. The median age at diagnosis was 23·2 months (IQR 11·0–36·5). Extraocular tumour spread (cT4 of the cTNMH classification) at diagnosis was reported in five (0·8%) of 636 children from high-income countries, 55 (5·4%) of 1027 children from upper-middle-income countries, 342 (19·7%) of 1738 children from lower-middle-income countries, and 196 (42·9%) of 457 children from low-income countries. Enucleation surgery was available for all children and intravenous chemotherapy was available for 4014 (98·8%) of 4064 children. The 3-year survival rate was 99·5% (95% CI 98·8–100·0) for children from high-income countries, 91·2% (89·5–93·0) for children from upper-middle-income countries, 80·3% (78·3–82·3) for children from lower-middle-income countries, and 57·3% (52·1–63·0) for children from low-income countries. On analysis, independent factors for worse survival were residence in low-income countries compared to high-income countries (hazard ratio 16·67; 95% CI 4·76–50·00), cT4 advanced tumour compared to cT1 (8·98; 4·44–18·18), and older age at diagnosis in children up to 3 years (1·38 per year; 1·23–1·56). For children aged 3–7 years, the mortality risk decreased slightly (p=0·0104 for the change in slope). Interpretation: This study, estimated to include approximately half of all new retinoblastoma cases worldwide in 2017, shows profound inequity in survival of children depending on the national income level of their country of residence. In high-income countries, death from retinoblastoma is rare, whereas in low-income countries estimated 3-year survival is just over 50%. Although essential treatments are available in nearly all countries, early diagnosis and treatment in low-income countries are key to improving survival outcomes.
