This article attempts to portray the competition of forces in the Indonesian democratic system, with the Ahmadiyya movement as the test case for the “contestation”. This article takes into account the reformation era as the landscape of the study, since this era opens a relatively wider opportunity for many entities to freely express their ideas and actions. Exploring the socio-political approach, this study comes up with the following findings: first, in the sociological domain, as predicted by Dawam Rahardjo, moderates defeat radical Indonesian Islam as the former outnumber the latter. However, in the political domain, as pointed out by Martin van Bruinessen, since the moderate Islam is just a silent majority, then the radical Islam wins the competition - marked by the issuance of the SKB Tiga Menteri, because the factor at work in the winning of this political competition is more on the “logic of power”, rather than the “power of logic”. The victory of the radical Islam in the political domain in turn implies at the failure of the Ahmadiyya movement in its struggle for survival in Indonesia.

Grounding on Ian Graeme Barbour’s (1923-2013) typology of relationships between science and religion, this article addresses the issue of the spiritual journey, with special reference to the discourse of stations (maqa>ma>t) and states (ah}wa>l), in the context of humanity study, that is, psychology of religion. According to Barbour, there are four types of relations between science and religion, namely conflict, independence, dialogue, and integration. Following the tendency of the third and the fourth relationships of science and religion, this study argues that there exists a melting point of spirituality, in this regard stations and states of spiritual journey, on the one hand, and psychology of religion, on the other. In this light, this article strengthens the illustrative studies on dialogical encounters between spirituality, in the field of mystical philosophy, and the psychology of religion, in the context of humanity studies.

Technological advancements have catalyzed a shift in buying and selling practices, ushering in the e-commerce era that enables online transactions anytime, anywhere. Despite the opportunities and conveniences offered by e-commerce, the practice of 'hit and run' by consumers, where goods are ordered without payment, has garnered attention. This has led to financial losses for business owners. The focus of this study is to comprehend the legal safeguards available to business owners against 'hit and run' consumer behaviors in online transactions. Through this research, a detailed examination will be conducted on the legal grounds that business owners can utilize to take legal action against consumers who violate contracts through 'hit and run' tactics. The research methodology employed is normative, utilizing a literature review approach. Research data is sourced from relevant regulations, particularly Law Number 8 of 1999 concerning Consumer Protection (UUPK). The objective of this research is to assess the legal protection afforded to business owners in online buying and selling transactions. The analysis centers on the rights of business owners as delineated in the UUPK and the legal justification for business owners to pursue legal action against consumers.Keywords: E-commerce, Consumers,Legal Protection, Breach of Contract,Buying and selling

Superposition of waves experiment in physics subject need more innovation to dig up student knowledge about the essential of waves in physics. Such innovation is using Audacity software for analyze it. The purpose of this study is to analyze the superposition of sound waves using Audacity software in the wave superposition experiment. The method used is to prepare tools and materials, namely PC/laptop, 250 Hz, 1 kHz audio files and Audacity Software. Then, 250 Hz and 1 kHz audio is sampled in one wave using Audacity after which each audio sample is imported twice and then combined with Audacity software and saved. This is done for different audio frequencies as well. Then, the results of the merger are opened with Audacity and then analyzed and compared with the initial wave. And the resulting superposition of two 250 Hz waves produces an amplitude of twice and 250 Hz and 1 KHz is produced over a 4 ms wave period and the constructive and destructive wave amplitudes depend on the phase of the two waves. Thus, wave superposition experiments using Audacity software facilitate the analysis of superposition results and characterize the period and amplitude properties of waves.
