Abstract

Tulisan ini mengkaji persoalan batas usia pernikahan di Indonesia dari perspektif hukum Islam dan peraturan perundang-undangan nasional. Dalam konteks hukum positif Indonesia, batas usia minimal pernikahan telah diatur dalam Undang-Undang Nomor 1 Tahun 1974 dan mengalami perubahan melalui Undang-Undang Nomor 16 Tahun 2019 yang menyamakan usia minimal menikah bagi pria dan wanita menjadi 19 tahun. Sementara itu, dalam hukum Islam, tidak ditemukan batas usia minimal secara eksplisit, namun syarat baligh dan kesiapan fisik serta mental menjadi pertimbangan utama. Artikel ini juga membahas tentang praktik dispensasi nikah yang muncul sebagai solusi hukum atas pernikahan di bawah umur. Pendekatan fikih menunjukkan perbedaan pandangan antar mazhab mengenai usia baligh, sedangkan hukum nasional memberikan batasan lebih tegas demi perlindungan anak dan ketahanan keluarga. Kesimpulannya, dispensasi nikah merupakan jalan tengah antara prinsip-prinsip fikih dan perlindungan hukum terhadap anak, dengan menekankan pentingnya kematangan calon mempelai baik secara fisik maupun psikis.

Abstract

To speak English, someone, especially among students, needs to master several verbs, and one of the obstacles to speaking English is the lack of verbs among students. Therefore, students face various obstacles. Anxiety is one of the biggest obstacles for students. Therefore, the purpose of this research is to find out what is students' anxiety and what factors cause students' anxiety when speaking in English in class. The sample of this study was MIPA 5 students of XI class of SMAN 1 Parepare which consisted of 35 students. The approach used in this study is descriptive research and qualitative. This study uses two research instruments namely Horowitz et al. (1986) used the Foreign Language Classroom Anxiety Scale (FLCAS) and interviews. The questionnaire had 33 items consisting of 9 positive and 24 negative statements on a Likert scale of 1-5 points, while the interview consisted of 10 questions. According to the survey's findings, there was only 1 respondent with a "Very Anxious" anxiety level or 3%, 5 respondents had "Anxious" anxiety levels or 14%, 6 respondents had "Mildly Anxious" anxiety levels or 46%, 13 respondents had "Relaxed" anxiety levels or 37%, and there were no students with a "Very Relaxed" anxiety level. Considering this, it can be said that the students in Class XI MIPA 5 SMAN 1 Parepare are generally "Mildly Anxious" when speaking English in class. According to the results of the interviews, it is clear that some students who are learning English in a classroom setting still experience anxiety. The factors contributing to this include a lack of vocabulary, imprecise pronunciation, a lack of confidence, being unprepared if the teacher calls on a student to speak in English without warning, and a lack of motivation on the part of the students. From 35 students in class XI MIPA 5, the researchers only interviewed 14 sources.

Abstract

In this study, the authors conducted a study on the analysis of the effect of oxy-acetylene welding joints on tensile strength and microstructure in the HAZ and weld metal areas on st 37 steel plates. The results of this study indicate that the average value of the highest tensile strength value is at V groove weld with the average strength of the welded joint is 4.796 kgf/mm2. While the lowest tensile stress is on the I groove weld of 4.674 kgf/mm2. Meanwhile, from the microstructure test, it can be seen that in the HAZ area each groove. Microstructure in the HAZ area shows that the double V groove  weld types are fine ferrite, coarse pearlite and martensite. In type V groove  weld the structures formed are ferrite, coarse pearlite and martensite. In type I groove  weld the structures formed are ferrite, grain boundary ferrite and fine pearlite. Whereas in the weld metal area, and the results of the microstructure test of the weld area on the V seam, it shows a dense microstructure arrangement, the arrangement is identical to pearlite (dark color) so that the specimen is harder.

Abstract

Citric acid was utilized as a bonding agent in the production of Sembilang bamboo particleboard. The limitation in using bamboo for particleboard production is that the silica content in bamboo skin can accelerate particleboard processing machines' bluntness and reduce particle adherence in particleboard manufacturing. This research aimed to investigate the influence of bamboo skin and citric acid content on the characteristics of Sembilang bamboo particleboard. Particleboards were prepared using bamboo particles (type A) and unskinned bamboo particles (type B). The citric acid solution (59%) was sprayed over the surface of bamboo particles to obtain three different levels of citric acid, i.e., 15, 20, and 25 % (based on bamboo particles’ dry weight). The Sembilang bamboo particleboards were manufactured using a hot-pressing machine at 200°C, 5 MPa for 10 min. The particleboard targeted density was 0.8 g/cm3. The type B particleboards’ internal bond (IB), modulus of rupture (MOR), water absorption (WA), and thickness swelling (TS) were superior compared to the type A particleboards. This was influenced by the lower concentration of silica in type B particleboards, which tend to allow an intimate contact area among particles and citric acid then produced better quality particleboards compared to type A particleboards. The type B particleboards met the obligation of JIS A 5908 for type 18 particleboard in terms of modulus of rupture, modulus of elasticity, and internal bond, however, only fulfilled the type 8 particleboard in terms of screw holding power.

Abstract

The demands of 21st century learning emphasize the importance of developing higher-order thinking skills through assessments aligned with the revised Bloom’s Taxonomy. However, mathematics assessment practices at the secondary education level are still predominantly focused on measuring lower-order thinking skills. This study aims to describe the characteristics and proportion of Higher Order Thinking Skills (HOTS) and Lower Order Thinking Skills (LOTS) items in the Advanced Mathematics Madrasah Assessment at Senior High School 1 Trenggalek. The study employed a descriptive approach using a combination of qualitative and quantitative methods through document analysis of 40 assessment items consisting of multiple-choice, complex multiple-choice, and short-answer questions. Each item was analyzed based on the cognitive levels of the revised Bloom’s Taxonomy (C1–C6) and classified into HOTS and LOTS categories. The results indicate that the assessment is still dominated by LOTS items, particularly at the C3 (applying) level, which emphasizes procedural skills. HOTS items were identified at the C4 and C5 levels, while the C6 (creating) level has not yet been accommodated. In terms of item format, multiple-choice questions tend to measure LOTS, whereas complex multiple-choice and short-answer questions are more likely to assess HOTS. These findings suggest that the assessment remains in a transitional phase toward strengthening higher order reasoning.

Abstract

Pengelolaan kinerja pegawai adalah aspek kunci dalam menjaga produktivitas dan kualitas kerja dalam institusi, dalam hal ini institusi pendidikan seperti UTDI. Dalam lingkungan kerja yang sangat kompetitif dan dinamis, penting bagi institusi untuk mengidentifikasi, mengakui, dan memberikan penghargaan kepada pegawai yang telah memberikan kontribusi yang luar biasa terhadap pencapaian tujuan. Untuk mencapai hal ini, seringkali menggunakan metode penilaian kinerja pegawai. Metode menentukan pemberian penghargaan kepada pegawai yang memiliki kinerja luar biasa, digunakan pendekatan gabungan yang terdiri dari metode Simple Additive Weighting (SAW) dan Analytic Hierarchy Process (AHP). Metode SAW digunakan untuk menghitung skor kinerja pegawai dengan memberikan bobot pada kriteria penilaian. Bobot ini didasarkan pada perbandingan pentingnya masing-masing kriteria. Penilaian kinerja menggunakan metode AHP dan SAW memberikan hasil yang sistematis dan dapat dipertanggungjawabkan. Visualisasi yang disajikan membantu memperkuat pemahaman terhadap hubungan antar kriteria dan bagaimana kinerja pegawai dinilai secara keseluruhan. Metode ini sangat bermanfaat dalam konteks penilaian multi-kriteria di berbagai organisasi.
