a marriage need to be studied further. The importance of knowing the most important elements in marriage will minimize conflict and even divorce. The method used in this research is a descriptive qualitative method with data collection techniques based on literature studies. The study of marriage and all components of marriage is the object of this research. The main research data comes from the book "A Triangular Theory of Love" by Robert J. Sternberg and "The Seven Principles for Making Marriage Work" by John Gottman. Apart from that, supporting data such as books and articles related to marriage and studies of love in married life are also used as supporting references. The research results show the dynamics of changes in the type of love during marriage. There are three components to love including: (1) the intimacy component; (2) passion component; and (3) commitment component. These three components can form different types of love. The love component can increase and decrease and even disappear. However, the component of love that is a factor in a marriage lasting a long time is the component of commitment. This is because even if the passion and intimacy of a husband and wife change, if the marriage commitment is maintained firmly, the marriage will still be able to survive. The commitment component in love is the most important element in marriage which is the reason for the formation and survival of a marriage.

Abstract:Abstract: Disposal of water in traditional boats is currently still done manually with human intervention, in contrast to commercial ships that already have a ballast system. This will certainly be a problem for boat users…
rs who can interfere with their sailing. Therefore, in this study, a design for an automatic water pump on an Arduino Uno-based boat will be made, which functions as a tool to remove puddles in the hull of the boat due to leakage. This tool is able to discharge water on the boat automatically when the water level entering the hull of the boat has exceeded the maximum height limit until the water level is within the tolerance limit which is considered safe and does not interfere with sailing. This tool works automatically using the WLC sensor (water level control) as a tool to monitor the water level, and the Arduino Uno system as a component to run the program by switching the pump. This tool can minimize the occurrence of shipwreck accidents due to boat hull leaks and human error. This system is still applied in the form of a prototype.

Abstract:Abstract: Tax literacy among Indonesian youth remains relatively low and has not yet become an integral component of formal learning at the senior and vocational high school levels. National data indicate that financial…
literacy stands at 49.68%, while specific understanding of taxation among young people is reported to be lower than that of the productive-age population. In addition, tax return compliance among individuals under 25 years old remains limited, reflecting weak early tax awareness and tax morale. In Magelang, high school students as future taxpayers generally lack access to contextual and practice-oriented tax education. This community engagement program aims to enhance tax literacy, awareness, and basic understanding of taxation among senior and vocational high school students through a structured and participatory educational approach. The methods included interactive lectures, contextual discussions, daily tax case studies, and simple tax calculation simulations, supported by pre- and post-tests to measure learning outcomes. The results demonstrate a significant improvement in students’ tax literacy scores and attitudes toward future compliance. The program also produced a tax literacy module and initiated student tax awareness groups in partner schools. Early tax education is therefore effective in strengthening youth tax morale and supporting sustainable national development.

Abstract:The implementation of YOLOv4 technology in the image-processing-based learning system at SMK Negeri 2 Tanjungbalai aims to enhance students' understanding of various electronic components in the Audio-Video Engineering field.…
ield. Currently, the learning process is still conducted manually, where teachers bring components such as resistors, capacitors, and other electronic parts. This method presents challenges in teaching the names of electronic components, as manual learning requires more time and students must recognize each component physically, one by one. Furthermore, students need to process resistor color codes and IC markings, which demand significant time and understanding. The YOLOv4 algorithm, known for its efficiency and accuracy, is utilized to detect and identify the type and value of components such as resistors, capacitors, transistors, and ICs automatically. This community service activity includes training, workshops, and the implementation of an image-processing-based application designed to assist students in a more interactive and efficient learning process. The results of this initiative indicate that the use of this technology positively impacts students' comprehension and improves the effectiveness of learning media in the school laboratory.

Abstract:The design of a lighting automation system for dragon fruit plants uses an LDR sensor as a light intensity detector. This system is supported by a solar module with a capacity of 10-20 watts to supply power to a 12V battery…
ery which is paralleled to 24V. This voltage was then changed by the inverter to 220VAC to light 10 lights as research samples. Tests show that the LDR sensor works optimally at 5VDC voltage. If the voltage supplied is less or more than 5VDC, the sensor cannot function properly. Analysis of the conversion of ADC values to output voltage shows consistent results according to the test table. In addition, using 12VDC voltage directly on the LDR causes the sensor to not function because the LDR is designed for low voltage (≤5V). Without a suitable resistor, excessive current can damage sensor components. The system design is able to minimize the use of electricity sources from PLN and is an energy-saving solution for lighting dragon fruit plants in the field.

Abstrak: Rancangan sistem otomatisasi lampu pada tanaman buah naga menggunakan sensor LDR sebagai pendeteksi intensitas cahaya. Sistem ini didukung oleh modul surya berkapasitas 10-20 watt untuk menyuplai daya ke baterai 12V yang diparalel menjadi 24V. Tegangan ini kemudian diubah oleh inverter menjadi 220VAC untuk menyalakan 10 lampu sebagai sampel penelitian. Pengujian menunjukkan bahwa sensor LDR bekerja optimal pada tegangan 5VDC. Jika tegangan yang diberikan kurang atau lebih dari 5VDC, sensor tidak dapat berfungsi dengan baik. Analisis konversi nilai ADC ke tegangan output menunjukkan hasil yang konsisten sesuai tabel pengujian. Selain itu, penggunaan tegangan 12VDC langsung pada LDR menyebabkan sensor tidak berfungsi karena LDR dirancang untuk tegangan rendah (≤5V). Tanpa resistor yang sesuai, arus yang berlebih dapat merusak komponen sensor. Rancangan sistem mampu meminimalisir penggunaan sumber listrik dari PLN dan menjadi solusi hemat energi untuk penerangan tanaman buah naga di lapangan.

Abstrak: Pelaksanaan PkM ini di laksanakan selama ± 9 bulan dalam beberapa tahapan, yang dimulai dengan observasi dan diakhiri dengan analisis kelayakan usaha. Kegiatan ini diselenggarakan melalui program kemitraan dengan badan usaha milik desa (BUMDes) Borong Pa’la’la dan beberapa warga pemilik kolam. Budidaya ikan nila dalam PkM ini menggunakan media kolam terpal (bioflok). Hasil analisis kelayakan usaha memberikan bukti jika terdapat empat komponen biaya (selain lahan) yaitu terpal, bibit, pakan ikan, peralatan dan biaya listrik yang secara keseluruhan biaya yang dbutuhkan untuk masa budidaya selama empat bulan yaitu sebesar Rp.2.560.000,- / 214 kg. (1500 ekor) yang dibudidayakan dapat menghasilkan penjualan pada kisaran harga Rp.26.000,- untuk setiap kilogramnya, sehingga menghasilkan Rp 5.226.000,- yang diperoleh dari 201 kg x Rp. 26.000,-. Hasil budidaya ikan nila yang dilakukan warga desa, BUMDes dan kelompok pengabdi terbukti dapat memberikan pendapatan tambahan warga, sebesar Rp.2,666.000,- (Rp.666.500,-/bulan). Hasil ini tergolong kecil jika digunakan sebagai penopang ekonomi warga desa, namun dapat digunakan sebagai tambahan pendapatan warga sehingga kepada warga melalui hasil PkM ini diberikan rekomendasi hanya sebagai pendapatan tambahan yang berorientasi untuk memanfaatan lahan kosong yang dimiliki warga desa.
