Abstract

Plastics are the synthesis of polymerization of different types of monomers. Almost all kinds of plastic will drift or float inside the water body. It will cause the plastic to be torn apart and damaged by the sunlight, oxidation and abrasion of mechanically forming plastic particles. Ecobrick is one way of handling plastic waste by packing clean and dry plastic into plastic bottles. Community empowerment to process plastic waste into something useful in the long term is one of the keys to the success of the plastic waste recycling program. This activity will provide benefits for community service participants, members who implement counselling, higher education and government. The target audience in these community service activities is the village community Bunga Raya, Siak regency. Results of public service activities that have been implemented by the community have been able to make seats from Ecobrick. In society, it is expected not only to make seats from Ecobrick but also to create other creations. So it can be used as a new business opportunity for the target community.

Abstract

Ikan nila merupakan ikan budidaya yang disukai oleh masyarakat karena dagingnya yang gurih dan lezat. Untuk peningkatkan produksi ikan nila diperlukan pakan yang cukup, baik kualitas maupun kuantitasnya. Pakan merupakan komponen biaya operasional utama pada budidaya ikan nila yang diperkirakan mencapai 40%-60%. Untuk mengatasi hal tersebut diperlukan teknologi yang dapat menekan biaya operasional dalam sistem budidaya. Tujuan dari penelitian ini adalah mengevaluasi frekuensi pemberian pakan yang berbeda terhadap pertumbuhan dan sintasan ikan nila merah (Oreochromis niloticus) yang dipelihara dengan sistem bioflok. Metode yang diterapkan adalah eksperimen dengan empat perlakuan dan tiga kali ulangan. Perlakuannya adalah frekuensi pemberian pakan pelet yaitu (A) 1 kali/hari, (B) 2 kali/hari, 3 kali/hari, dan 4 kali/hari. Ikan nila ukuran 3,71 ± 0,11 cm dan bobot 4,49 ± 0,021 g dipelihara selama 56 hari dalam bak 100 L dengan padat tebar 16 ekor/bak. Ikan dipelihara dengan teknologi bioflok dan diberikan pakan setiap harinya sebanyak 5%/berat biomasa/hari. Hasil penelitian menunjukkan bahwa pemeliharaan ikan nila merah pada sistem bioflok dengan frekuensi pemberian pakan yang berbeda berpengaruh nyata (P<0,05) terhadap performa pertumbuhan, sintasan, dan efisensi pakan. Perlakuan frekuensi pemberiaan pakan 2 kali/hari merupakan perlakuan terbaik menghasilkan pertumbuhan bobot mutlak 23,07 ± 0,89 g; laju pertumbuhan harian 3,23 ± 0,05%; sintasan 91,66 ± 3,60%; dan efisensi pakan 96,73 ± 6,70%.Tilapia (Oreochromis niloticus) is a cultured fish that is favored by the public, because of its delicious meat and high protein content. To increase production, quality, and quantity of feed is needed, feed is the main component in the cultivation system and it is estimated that 40%-60% of the costs incurred in maintaining tilapia are needed. To overcome this, technology is needed that can reduce operational costs in fish culture. The purpose of this study was to evaluate the growth and survival of red tilapia with different feeding frequencies reared with a biofloc system. The research method applied was experimental with four treatments and three replications. The treatment was the frequency of feeding, namely (A) 1 time/day, (B) 2 times/day, 3 times/day, and 4 times/day. Tilapia were reared for 56 days in a 100 L tank with a stocking density of 16 fish/tank. Initial size 3.71 ± 0.11 cm and weight 4.49 ± 0.021. Tilapia are reared with biofloc technology and given daily feed of 5%/weight of biomass/day. The results showed that rearing red tilapia with different feeding frequencies in the biofloc system had a significant effect (P<0.05) on growth performance, survival, and feed efficiency. Treatment B with a frequency of feeding 2 times/day was the best, with absolute growthof 23.07 ± 0.89 g, daily growth rate of 3.23 ± 0.05%, survival rate 91.66 ± 3.60%, and feed efficiency 96.73 ± 6.70%.

Abstract

Digital lifestyle has become an integral part of university students' daily lives, involving the use of social media, digital devices, and digital content consumption. The development of digital technology has positive impacts, facilitating easy access to information and social interactions. However, excessive use can lead to digital stress, which negatively affects students' mental health. This study aims to identify the key factors influencing students' digital lifestyles and analyze their relationship with stress levels. A quantitative approach with a survey method was employed, using a questionnaire to measure digital lifestyle, including social media usage frequency and digital device interaction duration, along with the Perceived Stress Scale (PSS) to measure students' stress levels. The factor analysis results show that social media usage and prolonged interaction with digital devices are significant factors contributing to students' stress. Furthermore, sleep disturbances and social anxiety were identified as other significant factors associated with increased stress. The multivariate regression analysis confirmed that students who spent more time on social media reported higher stress levels, associated with social anxiety and sleep disturbances caused by digital addiction. This study suggests the importance of managing digital device usage and raising students' awareness of the negative impacts of excessive social media use. The findings imply the need for support from universities and mental health organizations to provide interventions that help students manage their digital lifestyles, reduce stress, and improve their mental well-being.
