Pengelolaan Ketidakhadiran Siswa Berbasis Aplikasi di SMK 1 Muhammadiyah Sangatta

Latar belakang penulisan jurnal ini adalah masalah absensi dan absensi mahasiswa selama masa pandemi COVID-19. Faktor penyebabnya juga sangat beragam. Oleh karena itu, jurnal ini bertujuan untuk mendeskripsikan bagaimana upaya pengelolaan siswa dalam meningkatkan kehadiran di SMK 1 Muhammadiyah Sangatta. Dalam penulisan jurnal ini merupakan jenis penelitian deskriptif kualitatif. Teknik pengumpulan data menggunakan wawancara, dan dokumentasi. Sedangkan alat analisisnya adalah dengan menggunakan pemadatan data, penyajian data, dan penarikan kesimpulan. Penelitian ini menunjukkan bahwa manajemen siswa tertuang dalam rencana korektif melalui langkah-langkah yang diterapkan pada siswa bermasalah. Organisasi tersebut dilaksanakan atas kerjasama antara guru BK, siswa, dan wali kelas. Siswa sering menjumpai implementasi melalui sosialisasi dengan berbagai media atau cara yang benar. Pengawasan dilakukan dengan dua cara oleh kepala sekolah yaitu observasi lapangan dan penerimaan laporan mingguan dan bulanan dari wali kelas, BK, serta dari siswa senior. Berdasarkan paparan di atas, peran personel sekolah dalam meningkatkan kehadiran siswa di SMKN 1 Muhammadiyah Sangatta terutama dapat dikategorikan "80%" tingkat kehadiran selama pandemi COVID-19 bukan merupakan indikator penilaian wajib untuk saat ini. Penelitian ini dapat direkomendasikan kepada personil sekolah untuk lebih memperhatikan dan memantau kehadiran siswa, agar siswa lebih rajin menghadiri pertemuan baik online maupun offline di sekola

PENGARUH KEAKTIFAN ORGANISASI TERHADAP PRESTASI BELAJAR MAHASISWA MANAJEMEN PENDIDIKAN ISLAM UIN ALAUDDIN MAKASSAR

The Effect of Organizational Activity on Student Achievement in Islamic Education Management at Uin Alauddin Makassar Learning achievement is the result of learning from the process that has been carried out based on changes in behavior obtained from the experience of students in their interactions with the environment. The sampling technique used was purposive sampling, because the sample selected was based on the criteria of students from the 2019 and 2020 batches who were active in the organization. Data was collected by means of a questionnaire via google form and the research instrument used was a questionnaire in the form of differential semantics. Organizational activity on learning achievement of Islamic Education Management students of UIN Alauddin Makassar the effect of organizational activity on 54.76% then the remaining 45.24% is influenced by other factors. By being active in organizations, students can have a positive impact, especially on soft skills that support their learning achievements such as broad knowledge and insight, public speaking or communication skills, building relationships, increasing value or quality as students who are creative, innovative and intellectually different from students at generally.Pengaruh Keaktifan Organisasi Terhadap Prestasi Belajar Mahasiswa Manajemen Pendidikan Islam Uin Alauddin Makassar    Prestasi belajar merupakan hasil belajar dari proses yang telah dilakukan berdasarkan dari perubahan tingkah laku yang didapatkan dari pengalaman peserta didik dalam interaksinya dengan lingkungan. Teknik pengambilan sampel yang digunakan ialah purposive sampling, Sampel dipilih berdasarkan kriteria mahasiswa yang aktif dalam organisasi angkatan 2019 dan 2020. Pengumpulan data dengan kuesioner dan instrumen penelitian yang digunakan ialah angket berbentuk semantik diferensial yang disampaikan melalui google form. Hasil penelitian menunjukkan terdapat pengaruh yang signifikan keaktifan organisasi terhadap prestasi belajar mahasiswa Manajemen Pendidikan Islam UIN Alauddin Makassar dengan nilai signifikansi 0,00 < 0,05 dan keaktifan organisasi (variabel x) terhadap prestasi belajar sebesar 54,76% kemudian sisanya 45,24% dipengaruhi oleh faktor lain. Keaktifan mahasiswa dalam berorganisasi dapat memberikan dampak positif terutama pada kemampuan soft skill yang menunjang prestasi belajarnya seperti pengetahuan dan wawasan yang luas, kemampuan public speaking atau komunikasi, membangun relasi, meningkatkan value atau kualitas sebagai mahasiswa yang kreatif inovatif serta berintelektual yang berbeda dengan mahasiswa pada umumnya

[Cr(III)8M(II)6](12+) Coordination Cubes (M(II) =Cu, Co)

[Cr(III)(8)M(II)(6)](12+) (M(II)=Cu, Co) coordination cubes were constructed from a simple [Cr(III)L(3)] metalloligand and a “naked” M(II) salt. The flexibility in the design proffers the potential to tune the physical properties, as all the constituent parts of the cage can be changed without structural alteration. Computational techniques (known in theoretical nuclear physics as statistical spectroscopy) in tandem with EPR spectroscopy are used to interpret the magnetic behavior

Controlling the assembly of cyclotriveratrylene-derived coordination cages

A review of the emerging field of cyclotriveratrylene-derived coordination cages is presented. Ligand-functionalised cyclotriveratrylene (CTV) derivatives self-assemble with a range of metal cations to afford coordination cages, polymers and topologically non-trivial constructs, such as [2]catenanes and a self-entangled cube. Increased control over their self-assembly allows for the controlled and predictable formation of well-defined coordination cages for application in host-guest and recognition chemistry, with surfactant binding and single-crystal-to-single-crystal (SCTSC) uptake of small-molecule guests being observed

Hydrogen Storage Materials for Mobile and Stationary Applications: Current State of the Art

One of the limitations to the widespread use of hydrogen as an energy carrier is its storage in a safe and compact form. Herein, recent developments in effective high-capacity hydrogen storage materials are reviewed, with a special emphasis on light compounds, including those based on organic porous structures, boron, nitrogen, and aluminum. These elements and their related compounds hold the promise of high, reversible, and practical hydrogen storage capacity for mobile applications, including vehicles and portable power equipment, but also for the large scale and distributed storage of energy for stationary applications. Current understanding of the fundamental principles that govern the interaction of hydrogen with these light compounds is summarized, as well as basic strategies to meet practical targets of hydrogen uptake and release. The limitation of these strategies and current understanding is also discussed and new directions proposed

[CrIII8MII6]12+ Coordination Cubes (MII=Cu, Co)

Four [CrIII8MII6]n+ (MII = Cu, Co) coordination cubes of formulae [Cr8Co6L24Cl12] (1), [Cr8Co6L24(SCN)12] (2), [Cr8Cu6L24(H2O)12](SO4)6 (3), and [Cr8Cu6L24Cl12] (4) (where HL is 1-(4-pyridyl)butane-1,3-dione), were synthesised using the [CrIIIL3] metalloligand in combination with a variety of MII salts. The metallic skeleton of each cage describes a cube in which the [CrIIIL3] moieties occupy the eight vertices and the MII ions lie at the centre of the six faces. The axial coordination sites of the MII cations are occupied by either H2O molecules or Cl?/SCN? anions originating from the MII salt used in the synthesis, resulting in neutral 1, 2 and 4 and the cage in 3 being a 12+ cation; the charge-balancing SO42? anions accommodated both inside and outside the cube. Magnetic susceptibility and magnetisation measurements reveal weak exchange between nearest neighbour metal ions, mediated via the L? ligands. The modular assembly of the cubes suggests that any combination of [MIIIL3] metalloligand and MII salt will work, potentially resulting in an enormous family of supramolecular assemblies. The charge of the cubes is controlled by the nature of the ligand occupying the axial sites on the MII ions, suggesting trivial ligand exchange may offer control over, amongst others, solubility, reactivity, post-synthetic modification and substrate specificity. The large internal cavities of the cubes also suggest host–guest chemistry may be a fruiful route to encapsulating magnetic and/or redox active guests which could be employed to control magnetic behaviour, and the construction of multifunctional materials

Metallo-cryptophanes decorated with Bis-N-heterocyclic carbene ligands: self-assembly and guest uptake into a nonporous crystalline lattice

Pd3L2 metallo-cryptophane cages with cyclotriveratrylene-type L ligands can be stabilized by use of a bis-N-heterocyclic carbene as an auxiliary cis-protecting ligand, while use of more common protecting chelating ligands such as ethylenediamine saw a Pd3L2 to Pd6L8 rearrangement occur in solution. The crystalline Pd3L2 complexes act as sponges, taking up 1,2-dichorobenzene or iodine in a single-crystal-to-single-crystal fashion despite not exhibiting conventional porosity
