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.

This study aims to find out the strategy of utilizing the management of the Motaain border area in an effort to alleviate poverty in Silawan Village. This research was conducted at the Motaain Border of Silawan Village, Belu Regency using primary and secondary data. The results of this study show how the SO (Strength-Opportunity) strategy uses adequate natural resources, locations close to PLBN and the existence of animal feed factories by taking advantage of opportunities such as in the agriculture and plantation, tourism and trade and logistics sectors to increase the economic activities of the local community and be able to reduce poverty in Silawan Village. The obstacles that are often faced in poverty alleviation in Silawan Village are limited resources, economic activities that occur are more dominant in the outside community and security that is still weak so that smuggling often occurs. The location close to PLBN and the existence of a animal feed factory are expected to provide alternative solutions for farmers to manage agricultural products into animal feed and revive the culture of livestock in border areas.

Information technology has emerged to make various activities easier. One of the important roles of information technology is in providing disaster information. River Care Communities (KPS) which are currently spread across several regions in Indonesia, one of which is River Care Communities Opak Gajah Wong. River Care Communities have an important role in helping reduce disaster risks along river flows. There are various kinds of events that have the potential to cause disasters along river flows, including accumulation of rubbish, landslides on river walls, narrowing and shallowing of rivers, rising water discharge above normal limits and the growth of wild plants that can obstruct river flow. Currently the River Care Community only reports its activities conventionally and has not maximized the existence of information technology. With this conventional method, the delivery of incident reports along the river which is their area of ??activity is often late, the coordinates are inaccurate and confusing because they are not accompanied by visual images. The conventional pattern of submitting reports means that these reports are too late to be followed up by the relevant agencies and are often simply overlooked. To answer the problems mentioned above, the author conducted research by developing an E-Report application based on Android mobile application using the prototyping method. Currently, there are already several similar complaint applications, but they are not specific to problems that exist along the river flow. The form of complaints and reports in river basins has unique characteristics, where the reporter must enter certain values ??to determine the level of urgency of the report. With this application, it is hoped that every report from River Care Communities Opak Gajah Wong can be conveyed in real time and immediately receive follow-up from the relevant agencies.
