Pristine layered double hydroxide (LDH) in the form of clay Mg/Al LDH was enhanced its catalytic ability by impregnating metal oxides to form Mg/Al-metal oxide composites in congo red (CR) degradation. The composite was calcined at a not high temperature of 300 oC and characterized using SEM and DRUV. In this report, the photodegradation of CR as anionic dye was optimized based on the variables of pH, catalyst weight and time radiation. The stability of the catalyst was studied from the percent degradation in the recycling test. The characterization of the catalyst that has undergone 5th regeneration cycles was carried out using XRD and FTIR. The results of this study revealed that catalysis by Mg/Al-metal oxide composites resulted in a better percent degradation, rate constant and materials stability than pristine Mg/Al LDH. Mg/Al LDH, Mg/Al-TiO2 and Mg/Al-ZnO catalyzed the photodegradation of CR by 65.97%, 73.06 % and 86.86%, respectively.

One hundred and fifty-nine new workers in the government sector in Aceh Besar District were sampled to investigate whether their job satisfaction and engagement was influenced by organizational socialization tactics. Core self-evaluation is considered an important factor for newcomers who interact between organizational socialization tactics towards the outputs who were investigated in this study. Primary research data obtained from the results of questionnaires distributed to respondents who previously we have set. Structural Equation Modeling (SEM) supported by the AMOS 24 program is used to produce an accurate analysis of the primary data of this study. Based on the results of the analyzed data it was found that job satisfaction and work engagement of newcomers within the government sector organization in Aceh Besar District were influenced by factors of organizational socialization tactics in the organization itself. In addition, the results of the investigation data analysis also found that the core self-evaluation factor is important to be taken into account by newcomers when entering the organization that is now observed. Whether the results of this investigation in other places experienced the same thing, also discussed.

Tujuan tulisan ini ialah untuk mempermudah pembaca khususnya para mahasiswa Fakultas Syariah terkait mata kuliah ilmu falak agar lebih mudah memahami cara kerja perhitungan terkait penentuan hari dan pasaran serta hasil konversi tahun hijriyyah dan Tahun masehi. Dalam tulisan ini penulis menggunakan metode proses belajar mengajar dengan pakar Ilmu Falak dan penulis juga mengulang-mengulah kembali untuk mengerjakan sendiri di rumah. Hasil menunjukan bahwa dalam mengerjakan bidang falak ini sangat mudah apabila kita benar-benar dapat memahami rumus dan teliti dalam perhitunganya. Karena dalam menentukan hari, tanggal, bulan, tahun dan pasaran memerlukan perhitungan berupa perkalian, penjumlahan, pengurangan dan pembagian.
