Abstract

An analysis of functional groups using FTIR (Fourier Transform Infra Red) spectroscopy in test samples, such as petroleum and spiritus compound has been done.The spectral of the functional groups is observed by comparing of the absorption band which is formed on infra red spectrum with the infra red lines standard and comparing with other known compound. It is expected that functional group identification can be done effectively.Infra red spectrums of petroleum show the group of methyl (CH3), alkenes and aromatic compound. That results analysis is supported by appearance of bending symmetric vibration of C-H and the presence of stretching vibration of C=C from aromatic ring. The spiritus spectrums show the group of hydroxyl from alcohol compound. That analysis is supported by appearance of wide band on 3500–3000 cm-1 and appearance of band on 1000–1100 cm-1.  While test sample spectrum show the group of hidroksil (O-H) from primary alcohol, group of metil (CH3), triple bond (C≡C–H), group of nitril (R–C≡N), double bond (C=C) and C-N.   Keyword: FTIR spectroscopy, vibration, infra red spectrum, absorption, functional group

Abstract

Tujuan penelitian ini adalah untuk menganalisis pengaruh lingkungan pergaulan (social circle) terhadap perkembangan individu melalui pendekatan integratif multidisiplin. Metode yang digunakan adalah kajian pustaka sistematis dengan mengeksplorasi perspektif Psikologi Sosial, Agama Islam (dalam Al-Qur'an, Hadis, dan Tasawuf), Sejarah, dan Filsafat. Hasil analisis menunjukkan konvergensi yang signifikan antar disiplin ilmu mengenai kekuatan determinan lingkungan sosial. Dalam psikologi, teori Social Learning dan Conformity menjelaskan mekanisme peniruan dan penyesuaian diri. Agama Islam menegaskan hal ini melalui hadis Nabi tentang analogi penjual minyak wangi dan pandai besi, serta konsep ukhuwah. Tasawuf menekankan peran "Sohbet" (pergaulan dengan orang shaleh) untuk transfer cahaya spiritual (nur). Sejarah membuktikan melalui kelompok Renaissance dan halaqah sahabat Nabi bagaimana circle membentuk peradaban. Filosofi Aristoteles tentang "zoon politikon" memperkuat dasar manusia sebagai makhluk sosial. Simpulan penelitian ini adalah bahwa lingkungan pergaulan bukan hanya faktor pendukung, melainkan determinan fundamental yang mempengaruhi pola pikir, kebiasaan, ketahanan mental, standar hidup, dan arah masa depan individu. Implikasinya, intervensi melalui pembinaan komunitas positif (seperti halaqah dalam Islam) perlu menjadi strategi utama dalam pendidikan, dakwah, dan pengembangan masyarakat.

Abstract

The evaluation of the Marriage Management Information System (SIMKAH) is a study of the marriage registration service application implemented at the Muara Sugihan District Office of Religious Affairs (KUA), Banyuasin Regency. The focus of this study is to evaluate the extent to which SIMKAH contributes to improving the quality of marriage services in the region. The main objective of this study is to determine the effectiveness of SIMKAH in supporting the quality of marriage services. The approach used is field research with a descriptive method, where researchers try to describe and interpret the convenience and obstacles experienced by prospective brides and grooms when using the SIMKAH application to register for marriage. This becomes increasingly relevant considering that SIMKAH has undergone several system changes and developments. This research was conducted through direct field observations and interviews with prospective brides and grooms, SIMKAH operators, and the head of the local KUA (Religious Affairs Office). This research employed a qualitative approach, using primary and secondary data sources. The results indicate that several challenges remain in the implementation of SIMKAH at the Muara Sugihan District KUA, such as limited facilities and infrastructure and staff's lack of understanding of the application's use. Nevertheless, SIMKAH's implementation at the KUA can be categorized as quite effective. However, improvements in facilities and technical support are still needed to optimize services. Overall, SIMKAH provides significant benefits in the public service process, particularly in accelerating and simplifying marriage data searches and as a form of adaptation to technological advances.
