Anti-Mosquito Spray Based on Carbon Nanodots from Durian Peel Waste
No full textThe accumulation of organic waste can cause various diseases and environmental pollution. One of the diseases caused by this is Dengue Hemorrhagic Fever (DHF). Organic waste such as durian peel waste contains carbon, which can be processed into carbon nanodots (C-dots). The C-dots from durian peel waste can be used as a basic ingredient for mosquito repellent spray because durian peel contains essential oils, flavonoids, saponins, and tannins, which are toxic to mosquitoes. The synthesis of C-dots can also reduce environmental pollution due to durian peel waste. The purpose of this study was i) to prepare and characterize C-dots from durian peel waste using UV-Vis and PSA tests, and ii) to identify the effect of the C-dots solution in a mosquito repellent test in order to determine the ability of the anti-mosquito spray. This was an experimental study on the preparation of C-dots from durian peel waste using the two-steps low heating (TSLH) method. The anti-mosquito spray was made of 3 ratios of C-dots mass to distilled water volume, i.e.: (0.1 g : 200 ml); (0.2 g : 200 ml); and (0.3 g : 200 ml). Based on the results of the UV-Vis and PSA characterizations, it was found that the absorption peaks of the C-dots were at the wavelength interval of 288–332 nm and the sizes of the C-dots were 178.6 nm (69.3%) and 54.1 (20%). The mosquito repellent test showed that the anti-mosquito spray could repel and eradicate mosquitoes at the best ratio of (0.1 g C-dots : 200 ml of distilled water) with the highest mosquito’s mortality of 11 mosquitoes in 17 minutes and 29 seconds. This proves that the C-dots from durian peel waste can be used as an anti-mosquito spray

GENDER TRANSFORMATION-BASED DOMESTIC VIOLENCE VICTIM EMPOWERMENT MODEL IN NORTH ACEH DISTRICT
No full textThe North Aceh Regency ranks second in domestic violence (DV) cases in the Aceh Province, following the city of Banda Aceh. This study examines a Gender Transformation-based Empowerment Model for Victims of Domestic Violence, aiming to analyze and describe an economic empowerment model that enables victims to enhance their welfare and independence. Employing qualitative research methods through a phenomenological approach and literature review, data were collected via interviews with representatives from the North Aceh Office of Social Affairs, Women’s Empowerment and Child Protection, local government stakeholders, and victims of domestic violence. The findings reveal that economic factors are the predominant causes of domestic violence in North Aceh. Government assistance in the region remains largely focused on legal and psychological support, while economic empowerment initiatives are still limited in scope. The implementation of a Gender Transformation-based economic empowerment model offers victims access to economic resources and helps to challenge prevailing societal norms and power structures that marginalize women. This approach promotes gender equality by enabling victims to participate more actively in economic and social spheres, including access to education, vocational training, and employment opportunities

The evaluation adopts three key dimensions/indicators proposed by William N. Dunn to assess the implementation of PIP in Bandung Regency: (1) Effectiveness, (2) Efficiency, and (3) Equity. These dimensions were chosen due to recurring issues identified in the implementation of PIP. This research employs a qualitative approach with an instrumental case study design, utilizing multiple sources of information, including observations, interviews, audio-visual materials, documentation, and reports during the research process. The study focuses on PIP beneficiaries among junior high school students in Bandung Regency. The findings reveal the analysis of PIP in Bandung Regency based on effectiveness, efficiency, and equity. First, in terms of Effectiveness, PIP has succeeded in reducing the dropout rate among junior high school students but has not significantly increased the transition rate from basic to secondary education in Bandung Regency. Second, regarding Efficiency, PIP lacks regular and tiered socialization and monitoring by program implementers. Additionally, delays in fund disbursement to PIP beneficiaries are common. Third, in the aspect of Equity, the quota distribution for PIP is not allocated based on the distribution of dropout rates across sub-districts. This indicates persistent inequities and uneven distribution of PIP benefits to intended recipients
Pendidikan kewarganegaraan sebagai sarana pembelajaran dalam menumbuhkan karakter bangsa pada mahasiswa di era digital
No full textPenelitian ini bertujuan untuk mengidentifikasi peran pendidikan kewarganegaraan dalam membangun karakter bangsa pada mahasiswa dan problematika pendidikan kewarganegaraan dalam membangun karakter bangsa pada mahasiswa. Penelitian ini menggunakan pendekatan kualitatif dengan metode penelitian kepustakaan. Teknik pengumpulan data dalam penelitian ini menggunakan studi dokumen. Analisis data yang digunakan adalah analisis induktif. Hasil penelitian menunjukkan peran pendidikan kewarganegaraan sebagai mata kuliah wajib kurikulum di era digital adalah untuk membangun pengetahuan kewarganegaraan, keterampilan kewarganegaraan dan sikap atau kepribadian kewarganegaraan, namun tujuan utamanya adalah membangun karakter bangsa, mengingat mata kuliah tersebut adalah leading sector dalam membangun karakter bangsa. Secara teoritis pendidikan kewarganegaraan sangat efektif untuk membangun karakter bangsa di era digital pada generasi muda khususnya mahasiswa, namun dalam implementasinya masih jauh dari harapan, karena masih banyak mahasiswa melakukan tindakan dan bersikap tidak sesuai dengan kepribadian bangsa, seperti melakukan tindakan pidana, bersikap apatis terhadap kepentingan bersama, dan ersiap individuali. Pendidikan kewarganegaraan memiliki beberapa problematika dalam membangun karakter bangsa di era digital, yaitu kurangnya jam mengajar karena di perguruan tinggi hanya 2 sks, kompetensi dosen yang kurang maksimal, mahasiswa lebih tertarik dengan budaya asing dari pada budaya bangsa Indonesia, dan motivasi belajar mahasiswa masih tergolong kurang karena masih banyak dosen yang belum bisa memanfaatkan teknologi digital dengan maksimalThis study aims to identify the role of civic education in building national character in students and the problems of civic education in building national character in students. This research uses a qualitative approach with literature research methods. Document studies were used for data collection techniques in this study. The data analysis used isinductive analysis. The results showed that the role of civic education as a compulsory curriculum subject in the digital era is to build citizenship knowledge, citizenship skills, and civic attitudes or personalities. Still, the main goal is to build the nation's character, considering that the course is a leading sector in building the nation's character. Theoretically, civic education is very effective in building the nation's character in the digital era in the young generation, especially students. However, its implementation is still far from expectations because many students still take actions and behave incompatible with the nation's personality, such as committing criminal acts, being apathetic towards common interests, and being ready for individuality. Civic education has several problems in building the nation's character in the digital era, namely the lack of teaching hours because in higher education, there are only 2credits, the competence of lecturers is less than optimal, students are more interested in foreign cultures thanIndonesian cultures, and student learning motivation is still relatively lacking because there are still many lecturerswho cannot utilise digital technology optimally.

Implementation of a Camera-Based Inspection System for Measuring the Diameter of 3D Printed Filaments Made from LDPE Water Bottle Caps
No full textAdvances in additive manufacturing technology are driving the need for high-quality, affordable, and sustainable filaments. In Indonesia, the demand for filaments and extruders is largely met through imports, prompting researchers to innovate and develop filament extrusion machines, including those at the Politeknik Manufaktur Bandung, which has developed a filament extrusion machine equipped with a camera-based inspection and control system to produce high-quality filaments from LDPE gallon cap waste. This system integrates a digital microscope camera and a microcontroller to monitor the diameter of the extruded filament and correct the diameter by controlling the speed of the pull motor to stabilize the diameter in real-time. Image processing uses a color-based edge detection algorithm, and camera calibration results show a precision of 0,009 mm/pixel. Diameter data is sent to the Arduino Mega, which then uses the L298N driver to control motor speed via the Sliding Mode Control (SMC) method. Test results show that at 15 RPM, the average filament diameter is 1,77 mm with an error of 1,14%, while at 20 RPM it becomes 1,56 mm with a larger error of 10,86%, compared to the standard commercial filament size of 1,75mm. SMC control also demonstrated better performance than PID in terms of system accuracy in reaching the set point. This system could serve as an economic and ecological solution for local recycled filament production, reducing dependence on imported products
