Kekurangan gizi menjadi masalah dalam tumbuh kembang anak yang dapat menyebabkan stunting, wasting, mudah terkena penyakit serta penurunan kecerdasan otak dan mental. Stunting di Kabupaten Sikka pada tahun 2022 sebesar 13,8% dari hasil e-PPGBM periode Bulan Agustus 2022. Untuk mengatasi masalah ini diperlukan klasifikasi status stunting yang sangat berpengaruh terhadap tumbuh kembang anak sehingga dapat memberikan perhatian lebih dari faktor stunting yang paling tinggi di suatu daerah. Dengan bertambahnya jumlah balita dan peningkatan kasus stunting, proses penyelesaian tidak bisa dilakukan dengan cepat. Selain itu, tidak semua petugas posyandu bisa menghitung status gizi balita secara manual. Oleh karena itu, agar orang tua dan kader posyandu dapat mengetahui kondisi anak lebih cepat, diperlukan sistem yang menggunakan model algoritma C4.5. Sistem ini mampu mengolah data numerik (kontinu) dan diskrit. Penelitian ini menggunakan 5 atribut, yaitu usia, inisiasi menyusui dini (Imd), tinggi badan, jenis kelamin, dan berat badan. Keistimewaan penelitian ini adalah penggunaan atribut Inisiasi Menyusui Dini (IMD) yang belum pernah digunakan dalam penelitian sebelumnya dengan data numerik. Penggunaan algoritma C4.5 untuk menganalisis hasil stunting dan menyajikannya dalam bentuk website menghasilkan tingkat akurasi yang tidak jauh berbeda dengan pembagian data latih dan data uji sebesar 92.68 dan 90.98% dengan Max Dept 10.

Hasil perbandingan prosentase kinerja processor dalam tiga kondisi dapat dilihat bahwa, rata-rata selilih yang paling besar berada pada pengujian perbandingan yang pertama. Karena perbadingan pada saat app tidak memainkan musik dengan app yang memainkan musik, processor memiliki selisih cenderung besar. Sedangkan pada pebandingan kedua kinerja processor cenderung stabil, hal ini dikarenakan pengujian perbandingan app sama-sama memainkan musik. Kemudian perbadingan ketiga processor hanya dibebankan intruksi untuk load data 1 track musik, sedangkan pembandingnya ditambakan load data musik dan effect. rata kinerja processor cenderung turun, hal ini dikarenakan saat app memainkan effect tidak menggunakan processor, namun app akan melakukan load code ke dalam memory.

The use of social media such as TikTok in mathematics education and row and sequence materials is still rarely explored, although it has the potential to change the paradigm of presenting supplementary materials. This is because generally additional material is presented through platforms that are specifically for learning such as Geogebra, learning modules, or Kahoot. This study aims to determine the effectiveness of TikTok-assisted learning supplements on the ability to understand concepts and students' interest in learning the material of arithmetic rows and series from the results of test work and questionnaires through pre-test and post-test that have been carried out. The population in this study were all students of class XI SMA Negeri 1 Manonjaya and the sample in this study were students of class XI IPA 5 SMA Negeri 1 Manonjaya. This study uses a quantitative approach with quasi-experimental research methods. The results of this study, namely: 1) the use of TikTok-assisted learning supplements is effective to improve students' concept understanding ability on the material of arithmetic rows and series; and 2) the use of TikTok-assisted learning supplements is not effective to increase students' interest in learning on the material of arithmetic rows and series. The use of TikTok-assisted learning supplements is said to be effective if there is a significant difference and an increase in the average value of N-Gain (normalized gain) of concept understanding ability and students' interest in learning in the experimental class is significantly better than the control class. For this reason, other research is needed regarding the effectiveness of a social media in the context of learning on the ability to understand concepts and students' interest in learning by using other social media and/or other cognitive aspects or affective aspects.
Penggunaan media sosial seperti TikTok dalam pendidikan matematika dan materi barisan dan deret masih jarang dieksplorasi, meskipun memiliki potensi untuk mengubah paradigma penyajian materi tambahan. Hal ini karena umumnya materi tambahan disajikan melalui platform yang khusus untuk pembelajaran seperti Geogebra, modul pembelajaran, atau Kahoot. Penelitian ini bertujuan untuk mengetahui efektivitas suplemen pembelajaran berbantuan TikTok terhadap kemampuan pemahaman konsep dan minat belajar peserta didik pada materi barisan dan deret aritmetika dari hasil pengerjaan tes dan kuesioner melalui pre-test dan post-test yang telah dilaksanakan. Populasi dalam penelitian ini yaitu seluruh peserta didik kelas XI SMA Negeri 1 Manonjaya dan sampel dalam penelitian ini yaitu peserta didik kelas XI IPA 5 SMA Negeri 1 Manonjaya. Penelitian ini menggunakan pendekatan kuantitatif dengan metode penelitian kuasi eksperimen. Hasil dari penelitian ini, yaitu: 1) penggunaan suplemen pembelajaran berbantuan TikTok efektif untuk meningkatkan kemampuan pemahaman konsep peserta didik pada materi barisan dan deret aritmetika; dan 2) penggunaan suplemen pembelajaran berbantuan TikTok tidak efektif untuk meningkatkan minat belajar peserta didik pada materi barisan dan deret aritmetika. Penggunaan suplemen pembelajaran berbantuan TikTok dikatakan efektif apabila terdapat perbedaan yang signifikan dan peningkatan nilai rata-rata N-Gain (gain ternormalisasi) kemampuan pemahaman konsep maupun minat belajar peserta didik pada kelas eksperimen lebih baik secara signifikan dibandingkan kelas kontrol. Untuk itu, diperlukan penelitian lain mengenai efektivitas suatu media sosial dalam konteks pembelajaran terhadap kemampuan pemahaman konsep dan minat belajar peserta didik dengan menggunakan media sosial lain dan/atau aspek kognitif atau aspek afektif lain.
 

The waiting time for ships is one of the problems that must be a concern at Tanjung Intan Port Cilacap and which is very influential for the smooth process of unloading coal from coal carriers to Tanjung Intan Port, Cilacap. This study aims to determine the factors that affect the ship's docking schedule, pilotage services, loading and unloading productivity on the waiting time of the ship. This research was conducted at Tanjung Intan Port, Cilacap. Data was collected through observation, literature study, interviews, documentation and questionnaires. The analysis technique used is multiple linear regression with the help of SPSS V.26 program. Based on the results of research and multiple analysis, the following equations are generated:Y = 0.254 +0.297X1+0.585X2+0.177X3+µ. Based on empirical facts and the results of multiple linear regression equations, it is shown that the Ship docking schedule variable (X1) has t count (3.409) > t table (1.98373), pilotage service variable (X2) has t count (5.809) > t table (1.98373), and loading and unloading productivity (X3) has t count (2.967) > t table (1.98373). As for the value of the adjuster R2 = 0.582. This means that 58.2% of the dependent variable (Y) can be explained by the independent variables, namely Ship docking schedules, guidance services, and loading and unloading productivity. While the rest (100% - 58.2%) = 41.8% is explained by other reasons outside the variables studied. Thus, the results of the study show that the availability of docks, guidance services, and loading and unloading productivity has a positive and significant effect on waiting time for ships at Tanjung Inttan port, Cilacap.
