Abstract

Perkembangan Ilmu Pengetahuan dan Teknologi saat ini sangat mendukung setiap kegiatan salah satunya adalah kegiatan keagamaan dan Easyworship merupakan salah satu dari aplikasi teknologi. Adapun tujuan dari kegiatan pengabdian ini adalah mentransfer pengetahuan dan teknologi pada masyrakat non produktif salah satunya adalah gereja. Dengan adanya kegiatan sosialisasi dan pelatihan easyworship mampu meningkatkan potensi pemuda-pemudi terhadap kreativitas dan inovatif dalam pelayanan peribadatan. Metode yang digunakan dalam kegiatan ini adalah pelatihan dengan membentuk small grup agar pelatihan ini lebih fokus kepada individu dan terkesan tidak monoton. Tim pengusul juga mendampingi tiap kelompok jika pada saat pelaksanaanya ada kendala yang dihadapi. Hasil dari kegiatan pengabdian ini adalah pemuda-pemudi di GBKP Tanjung Raja memperoleh pemahaman tentang aplikasi tersebut dan mereka juga semakin antusias untuk mengembangkan kemampuan masyarakat dalam mengoperasikan aplikasi easyworship yang menjadi perwujudan telah adanya kolaborasi teknologi di tempat tersebut.

Abstract

The year 2045 marks 100 years since Indonesia gained its independence. The government's vision for that year is Golden Indonesia 2045. In the final draft of the 2025-2045 RPJPN of the Ministry of National Development Planning / Bappenas there are five main targets of the 2045 Golden Indonesia Vision. In this article, a forecast is conducted using the Least Square method to determine whether Indonesia can achieve this vision by 2045. There are 8 aspects that will be forecasted which are considered to represent the five targets of Golden Indonesia 2045. The eight aspects are Human Development Index; Information and Communication Technology Development Index; Per Capita Income Data; Poverty Rate; Open Unemployment Rate; National Road Stability; Provincial Road Stability; and District and City Road Sustainability.

Abstract

Election issues are sensitive information among the society because they relate to people's survival in terms of work, economy and education. Election hoaxes where information whose truth cannot be ascertained becomes a weapon used by certain parties to bring down political opponents. Social media such as TikTok is a media that is often used to spread hoaxes because TikTok social media users come from various ages and there is no distance or time between users. In this paper, a mathematical model is presented to see how the equilibrium point is to be free from hoax based on the basic reproduction number R0. The spread of hoaxes on social media occurs if R0 > 1 and does not occur if R0 < 1. The model approach used is the SEIR mathematical model because it is seen that there are people who receive hoax videos (exposed) and then spread them without finding out the truth (infected), and users with this condition it needs to be recovered. The method used in this research is a literature review. The results obtained show that the mathematical model presented shows that the basic reproduction number R0 is zero (R0 < 1). This means that there will be no spread of election hoaxes

Abstract

Textile wastewater containing synthetic dyes poses serious environmental concerns due to its persistence and toxicity. Although TiO₂, ZnO, and activated carbon-based photocatalysts have shown promising degradation performance, limited studies have explored their integration into photocatalytic reactor systems. Therefore, a UV-assisted TiO₂/ZnO-activated carbon reactor was developed for methylene blue degradation. Therefore, this study aimed to develop and evaluate a UV-assisted photocatalytic reactor employing a TiO₂/ZnO-activated carbon (AC) composite derived from coconut shell waste for methylene blue degradation. This process begins with the production of activated carbon from coconut shell waste, which is ground into a powder and then ground using a mortar and pestle. The powder has activated with H2SO4 and stirred with a magnetic stirrer for 2 hours, accompanied by heating. The powder then filtered and heated in a microwave at 100°C until there is no water content in the carbon. The decrease in the degradation rate observed using a UV-VIS spectrophotometer. Concentration of MB are 50 ppm and 150 ppm, for 60 minutes with an optimal wavelength between 288-300 nm. Degradation efficiency reached 93.5% by 50 ppm, with the absorbance decreasing from 0.347828 at the 20 minutes to 0.064366 at the 60 minutes. Meanwhile, at a concentration of 150 ppm, degradation was recorded at 87.7%, with the absorbance decreasing from 0.494045 at the 20 minutes to 0.122852 at the 60 minutes. These results indicate that the developed UV-assisted TiO₂/ZnO-activated carbon photocatalytic reactor exhibits high performance for methylene blue degradation and offers a sustainable approach for textile wastewater treatment applications.
