Abstract

Functional grammar is a type of grammar discovered by Michael Halliday in the 60s. Even though this feels foreign to foreign language teachers at school, it is very interesting for scientific developers. In the field of language education, functional grammar is more commonly applied in terms of speaking and writing. The background to this is because functional grammar has an important purpose for foreign language students and provides facilities for foreign language students to know the language knowledge they need to know to be successful in school. This research hopes that researchers can find out whether there is a positive influence on the level of success of functional grammar knowledge in writing expository analytical texts during the second semester of the second year of SMA Muhammadiyah 1 Karanganyar. This research uses a quantitative design. Researchers used pretest and posttest to determine the effectiveness of the treatment used in this study. The final design is to determine the influence between research variables. The T test results show a sign (two-tailed) of 0.000 and a significance level of 0.05. The result is Sig. (two-tailed) is below the significance level, so the alternative hypothesis (Ha) is accepted and the null hypothesis (Ho) is rejected. This means that students who are given material using functional grammar are more able to write analytical and expository texts than students who are not given functional grammar. It can be interpreted that functional grammar has a very good influence in writing expository analytical texts. Functional grammar can be used to support writing analytical descriptive text. Students will be able to develop writing skills, especially expository analytical writing. This grammar can also make students more critical when creating analytical descriptive texts.

Abstract

PT XYZ merupakan suatu perusahaan agribisnis yang berfokus pada pengolahan crude palm oil (CPO) yang berlokasi di Indonesia. Pada praktiknya perusahaan masih belum menerapkan strategi preventive maintenance untuk perawatan mesin produksinya dan hanya mengandalkan corrective maintenance sebagai strategi dalam tindakan perawatan mesin. Berdasarkan data historis perusahaan yang ada pada bulan januari 2023-desember 2023 tercatat ada 96 kali tindakan perawatan yang dilakukan pada mesin niagara filter dan mesin tersebut memiliki nilai availabity terendah dibandingkan mesin yang lain sebesar 73,33%. Oleh karena itu peneliti berusaha melakukan evaluasi sistem perawatan mesin dengan menerapkan preventive maintenance berdasarkan klasifikasi ISMO. Preventive maintenance dengan klasifikasi ISMO mampu menentukan siklus perawatan dan estimasi biaya perawatan suatu mesin berdasarkan nilai repair complexity mesin yang akan diklasifikasikan dalam masing-masing kegiatan inspection, small repair, medium repair, and overhaul. Hasil penelitian menyatakan 1 siklus perawatan mesin niagara filter selama 3 tahun dengan rincian Inspection 9 kali, Small Repair 6 kali, dan Medium Repair 2 kali dan nilai availability mesin meningkat menjadi 88%. Sehingga, diperoleh total estimasi biaya perawatan mesin niagara filter dengan klasifikasi ISMO adalah sebesar Rp93.110.152,98.

Abstract

PT XYZ merupakan salah satu perusahaan manufaktur yang bergerak dalam bidang usaha industri keramik. Dalam pelaksanaan produksinya, masih ditemukan beberapa waste. Untuk mengurangi waste yang teridentifikasi dalam proses produksinya, digunakan penerapan Lean Manufacturing dengan metode VSM (Value Stream Mapping) untuk menganalisa dan merancang aliran material dan informasi sehingga dapat melakukan identifikasi, analisa dan mencari solusi untuk melakukan usulan perbaikan untuk mengurangi waste yang terjadi. Pada pelaksanaannya, dimulai dengan identifikasi waste yang dominan terjadi menggunakan kuesioner borda, selanjutnya dicocokkan dengan data perusahaan apakah waste tersebut benar terjadi atau tidak. Hasil identifikasi 3 waste dominan yang terjadi pada PT XYZ yaitu Overproduction, Defect dan Inventory. Usulan perbaikan yang diberikan untuk mengurangi waste yaitu, overproduction dengan peramalan yang mendapat hasil ramalan ke-13 sebesar 249,186.3 dengan nilai MAPE yang lebih kecil dari forecast perusahaan yaitu 0,75%, sehingga dapat digunakan untuk mengurangi waste overproduction sekaligus waste inventory dengan menambahkan perhitungan Safety Stock yaitu sebesar 9,162.54 unit dan defect dengan usulan perbaikan Root Cause Analysis dengan tools fishbone diagram untuk 3 defect dominan dan Kaizen 5W1H untuk merumuskan perbaikan yang tepat.

Abstract

The environmental issues caused by conventional plastic waste are becoming increasingly serious, driving the development of more eco-friendly bioplastics. This study examines the mechanical properties, solubility, and biodegradability of seaweed-based bioplastics with the addition of curcumin and anthocyanin as additives. The results indicate that bioplastics containing only anthocyanin exhibit the best tensile strength (3.78 ± 0.26 MPa) and elasticity (12.48 ± 0.49 MPa). In contrast, bioplastics containing only curcumin show the lowest mechanical properties. The addition of anthocyanin enhances tensile strength and elasticity through the formation of strong hydrogen bonds with seaweed polymers, whereas curcumin decreases mechanical properties due to less stable molecular interactions. In terms of solubility, anthocyanin recorded the highest value (72.04%), while curcumin had the lowest (37.61%) due to its lower water stability. Regarding biodegradability, the combination of anthocyanin (1.25%) and curcumin (3.75%), as well as pure curcumin (5%), showed the highest degradation rates, whereas a balanced mixture (2.5%:2.5%) exhibited the lowest biodegradability. In conclusion, anthocyanin improves the mechanical properties and solubility of bioplastics, while curcumin supports biodegradability. Seaweed-based bioplastics with added curcumin and anthocyanin show potential as eco-friendly antibacterial materials.

Abstract

This quantitative correlational study was conducted to find out the relationship between AI-Assisted English Learning, Tech Acceptance, and Willingness to Use English in the AI Learning, with the target population being the graduates of the English Language Education program at UIN Raden Mas Said Surakarta. There were 30 respondents taken for this quantitative correlation analysis, with the respondents completing an online questionnaire designed in relation to the AI usage scale, Tech Acceptance Model, and Willingness to Communicate. The data revealed that both predictors were found to be at high levels, denoting the involvement of the graduates in learning English and their positive attitude towards technology. AI-supported learning in English was revealed to be positively significant with Willingness to Use English (ρ =.386, p =.035), indicating that regular use of AI technologies boosts alumni confidence and drive when speaking English. In contrast, Willingness to Use English did not significantly correlate with Technology Acceptance (ρ =.155, p =.414). Nonetheless, the combination of the two variables explained 23.2% of the variance (R² =.232) and significantly contributed to the variation in Willingness to Use English (F = 4.085, p =.028). This result implied that the integration of AI with English language learning could enhance the quality of graduates’ communication preparedness, especially when they possessed an optimistic attitude towards technology. Future studies involving more factors, such as affective elements, should be conducted to further explore English language usage behavior post-graduation.

Abstract

The quality of measurement instruments is an essential factor in ensuring accurate and meaningful learning assessments. However, many test instruments have not undergone empirical validation, which reduces their reliability and accuracy. This study aimed to develop and empirically validate a conceptual understanding test on dynamic electricity for high school students. A quantitative descriptive design was employed involving 66 students who had studied the topic of dynamic electricity. Item analysis included validity, reliability, discrimination index, and difficulty level tests. The results showed that 11 multiple-choice items met the criteria for validity and reliability with appropriate levels of difficulty and discrimination. These findings indicate that the developed instrument has good quality and can consistently measure students’ conceptual understanding. Therefore, this test instrument can be used by teachers and researchers as a representative and high-quality tool to evaluate students’ conceptual mastery and improve the quality of physics learning assessment.
