Relevansi dan Implementasi Pemikiran Nurcholish Madjid terhadap Politik Indonesia

This paper is based on a literature study that aims to examine the relevance and implementation of Islamic politics in the political arena of Indonesia, the majority of which are Muslims. The results of the study concluded that in the era of 70s emerged ??Nurcholish Madjid's idea that "Islam YES, Islamic party NO" and it had established a new awareness for Muslims on the desired goal which is not idealism about the establishment of an Islamic State, but a just and prosperous society. Islam is no longer seen as a symbolic structure, but rather the spirit of values ??that are brought and developed in the life of the state. Efforts to articulate Islamic politics in Indonesia are important issues that need to be addressed to provide a possible synthesis between Islam and the State, therefore the study of Islamic political thought that is unique to Indonesia is not only attractive but urgent to do. In line with the conclusions above, it is expected that this paper can trigger students, especially those who choose the Department of Siyasah Jinayah so that Islamic political thought not only be a mere discourse but should be more focused on the aspect of its implementation to move towards a more advanced Indonesia

A model of magnetic order in hexagonal HoMnO3

Symmetry arguments are used to develop a spin Hamiltonian for the description of the complex magnetic ordering in HoMnO$_3$. Using a novel application of the Landau Lifshitz Gilbert dynamic torque equations to this model of the frustrated Mn ions on an $AB$ stacked triangular antiferromagnetic, it is shown that the four principal spin configurations observed in this compound are stabilized. Ho-Mn coupling is found to be a consequence of an unusual trigonal anisotropy term which is responsible for simultaneous Mn spin reorientation and onset of Ho magnetic order. Based on these microscopic considerations, a mean-field Landau-type free energy is derived which reproduces the succession of observed temperature driven magnetic phase transitions at zero field, including re-entrant behavior. In addition, our analysis suggests that the basal-plane magnetic order should be slightly incommensurate with the lattice.Comment: 9 pages, 3 figure

Theory of magnetic phases of hexagonal rare earth manganites

The magnetic phases of hexagonal perovskites RMnO_3 (R=Ho, Er, Tm, Yb, Sc, Y) are analysed using group theory and the Landau theory of phase transitions. The competition between various magnetic order parameters is discussed in the context of antiferromagnetic interactions. A phenomenological model based on four one-dimensional magnetic order parameters is developed and studied numerically. It is shown that coupling of the various order parameters leads to a complex magnetic field-temperature phase diagram and the results are compared to experiment.Comment: 11 pages, 14 figures.

Proses Pendidikan Insan Kamil Di Pondok Sufi Ilmu Syaththariah Pondok Pesantren Sumber Daya At-taqwa Tanjunganom Nganjuk Jawa Timur

This study tries to explore the education process of the perject man (insan kamil) in the sufi center/ zawiyyah of Ilmu Syaththariah. This study finds several points: firstly, in the Ilmu Syaththariah perspective, Wasithah is the elite respondent (the only reference) in having a religious. He is al-muthohharun (yang disucikan Tuhan) who is given ability to understand the Qur'an. The main fumtion of Wasithah is as the people of invocation (ahladz dzikri), uniting the human essence with the God essence in order that man can absolutety worship the God essence (not His name) when he conducts the religious activities. In praying, man must remember God in order that he is not sentenced to be negligent because one who is negligent to remember God is judged to come into the hell. Secondly, knowing the divine essence through being the people of invocation (ahli zikir) becomes the first step in the process of walking the way of being the perfect man. Then, it is followed by performing spiritual guide's advice wholeheartedly with heart, spirit, and intelledual intuition that always remember the essence of divine mystery. Thirdly, the education process of the perfect man emphasizes the consciousness of the discriples that being the perfect man is due to God's guidance. Therefore, the disciples are resuscitated in order to always hope obtaining His forgiveness, His merry, His help, His virtue, and always hope the Wasithah's grace and blessing. Man also hopes the easiness in performing all spiritual guides' advices until he reaches the spiritual degree (martabat) of the perfed man. Fourthly, the concept of the pe,fect man in the Ilmu Syaththariah perspective can be implemented in the education institutions. Based on the surory, it shows that the students who become the Syaththariah community look more faithful in the observance ef religious obligations than those who do not involve in this the Syaththariah community in the same education institutions

Dynamic fracture of inorganic glasses by hard spherical and conical projectiles.

In this article, high-speed photographic investigations of the dynamic crack initiation and propagation in several inorganic glasses by the impact of small spherical and conical projectiles are described. These were carried out at speeds of up to approximately 2×10(6) frames s(-1). The glasses were fused silica, 'Pyrex' (a borosilicate glass), soda lime and B(2)O(3). The projectiles were 0.8-2 mm diameter spheres of steel, glass, sapphire and tungsten carbide, and their velocities were up to 340 m s(-1). In fused silica and Pyrex, spherical projectiles' impact produced Hertzian cone cracks travelling at terminal crack velocities, whereas in soda-lime glass fast splinter cracks were generated. No crack bifurcation was observed, which has been explained by the nature of the stress intensity factor of the particle-impact-generated cracks, which leads to a stable crack growth. Crack bifurcation was, however, observed in thermally tempered glass; this bifurcation has been explained by the tensile residual stress and the associated unstable crack growth. A new explanation has been proposed for the decrease of the included angle of the Hertzian cone cracks with increasing impact velocity. B(2)O(3) glass showed dynamic compaction and plasticity owing to impact with steel spheres. Other observations, such as total contact time, crack lengths and response to oblique impacts, have also been explained.I acknowledge sincerely the many stimulating discussions on the phenomena of indentation, fracture and friction which I had over the past 35 years with the late Dr Elizabeth H. Yoffe, who passed away in July 2014. I thank Kelvin Fagan, the Cavendish Laboratory photographer, for his help with the figures.This is the accepted manuscript of a paper published in Philisophical Transactions A., 373: 20140135. http://dx.doi.org/10.1098/rsta.2014.013
