Abstract

Penelitian ini bertujuan untuk menentukan pengaruh pelarut terhadap aktivitas antioksidan ekstrak daun afrika (Gymanthemum amygdalinum (Delile) Sch. Bip.) menggunakan pelarut etanol dan butanol. Ultrasonic Assist Extraction (UAE) adalah metode ekstraksi yang digunakan dalam penelitian ini. Pada penelitian ini, dilakukan analisis total fenolik dan aktivitas antioksidan terhadap ekstrak daun afrika (Gymanthemum amygdalinum (Delile) Sch. Bip.). Kadar total fenolik ekstrak etanol daun afrika (Gymanthemum amygdalinum (Delile) Sch. Bip.) dengan metode Folin - Ciocalteau diperoleh sebesar (349,85 ± 0,21) mg GAE/g dan ekstrak butanol daun afrika (Gymanthemum amygdalinum (Delile) Sch. Bip.) memiliki kadar total fenolik sebesar (226,62 ± 1,63) mg GAE/g ekstrak. Aktivitas antioksidan ekstrak etanol daun afrika (Gymanthemum amygdalinum (Delile) Sch. Bip.) dengan metode FRAP diperoleh nilai IC50 sebesar (11,41 ± 0,03) mg/L dan ekstrak butanol daun afrika (Gymanthemum amygdalinum (Delile) Sch. Bip.) diperoleh nilai IC50 sebesar (12,35 ± 0,13) mg/L. Dari hasil IC50 antioksidadan diperoleh bahwa ekstrak daun afrika (Gymanthemum amygdalinum (Delile) Sch. Bip.) dengan kedua pelarut tersebut termasuk ke dalam kategori aktivitas sangat kuat sebagai antioksidan, sehingga pelarut butanol dapat digunakan sebagai pelarut alternatif pengganti etanol.Kata kunci: Ultrasonic Assist Extraction, antioksidan, Gymanthemum amygdalinum (Delile) Sch. Bip, pelarut alternatif

Abstract

This research focuses on the study of incumbents in Wonosobo Regency. The incumbent is seen as a candidate who has a high chance of running again as a candidate. Other studies have also looked at many incumbents running as single candidates. This research uses interview methods and literature studies using the oligarchy concept. the results of this study are that in the case of Wonosobo Regency,the incumbent failed to run as a candidate for regional head. With this failure, it shows that incumbents who have been seen as actors who can control political parties to nominate again, are the opposite of the case in Wonosobo where political parties can be independent. There are several factors that cause it. First, related to the parties' dissatisfaction with the incumbent leadership. Second, the leadershipstyle of the incumbent regent is distant from political parties. Third, existing political parties do not provide support for the incumbent's re-nomination. Fourth, the formation of a large coalition built by PDIP. This research uses a qualitative approach, with data collection methods of in-depth interviews and literature study.AbstrakPada beberapa kajian, incumbent dilihat sebagai calon yang memiliki peluang besar untuk maju kembali sebagaai calon. Kajian yang lain juga melihat bahwa banyak incumbent maju sebagai calon tunggal. Dalam kasus di Kabupaten Wonosobo yang terjadi sebaliknya,incumbent gagal maju sebagi calon kepala daerah. Dengan kegagalan tersebut menunjukkan bahwa incumbent yang selama ini dilihat sebagi aktor yang bisa mengendalikan partai-partai politik untuk mencalonkan kembali, untuk kasus di Wonosobo sebaliknya di mana partaipolitik bisa bersifat independent. Ada beberapa faktor yang menjadi penyebab. Pertama, terkait dengan ketidakpuasan partai-partai terhadap kepemimpinan petahana. Kedua, gaya kepemimpinan bupati petahana yang berjarak dengan partai politik. Ketiga, partaipartai politik yang ada tidak memberikan dukungan untuk pencalonan kembali petahana. Keempat, terbentuknya koalisi besar yang dibangun oleh PDIP. Penelitian ini menggunakan pendekatan kualitatif, dengan metode pengumpulan data berupa wawancara mendalam dan studi pustaka.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in supporting economic growth, absorbing labor, and reducing poverty, yet many entrepreneurs still face challenges in financial management, particularly in bookkeeping practices. This community service program was carried out to respond to the limited capacity of ceramic trading entrepreneurs in Pekanbaru, who often manage their businesses informally without proper financial recording, which hampers decision-making, cost calculation, and access to financial support. The purpose of this program was to improve the knowledge and skills of MSME entrepreneurs in preparing simple bookkeeping records adapted to their business characteristics. The method applied was the Participatory Action Research (PAR) approach, involving socialization, lectures, discussions, and mentoring that enabled participants to directly practice recording daily transactions and compiling basic financial reports such as balance sheets and income statements. The results show that participants were able to separate personal and business finances, record transactions more regularly, and recognize the strategic importance of bookkeeping for business sustainability. The drawn conclusion is that bookkeeping training contributes significantly to increasing financial literacy and competitiveness of MSMEs, although long-term mentoring is still required to strengthen consistency and adoption of digital tools. This program contributes practically by empowering local entrepreneurs and theoretically by affirming the relevance of financial literacy in MSME development.

Abstract

Local food security is a strategic issue in supporting national food independence and community welfare. However, small and medium food enterprises (SMEs) often face challenges in applying quality production standards, particularly the principles of Good Processed Food Production Practices (CPPOB). This community engagement activity aims to enhance the knowledge and awareness of SME actors regarding the importance of CPPOB implementation to ensure food safety and quality. The program consisted of three stages: preparation, implementation, and evaluation. The counseling was conducted at the production site of IKM Aji Berkah, which produces cassava and banana chips, using interactive lectures and discussions. Evaluation results showed an increase in participants' average scores from 63.52 to 89.92 after the program. All participants (100%) met the Minimum Mastery Criteria, and the paired t-test indicated a statistically significant improvement (P < 0.01). This activity proves that CPPOB counseling effectively strengthens SME actors’ capacity to produce hygienic and safe food, while also contributing positively to the enhancement of local food security.

Abstract

This study aims to analyze the relationship between teacher-student communication patterns and students' learning motivation in physics learning among 11th-grade students at SMAN 1 Sinunukan. The research is based on the importance of effective communication in creating a conducive learning environment, especially in physics, a subject often perceived as difficult by students. This study employed a quantitative method with a correlational approach. Data were collected through questionnaires distributed to 31 selected 11th-grade students. The results of the data analysis show a significant and positive relationship between teacher-student communication patterns and students' learning motivation, with a correlation coefficient (r) of 0.870 and a significance value (p) of 0.000. Furthermore, teacher-student communication patterns account for 75.6% of the variance in students' learning motivation. These findings highlight that open, empathetic, and two-way communication between teachers and students greatly contributes to enhancing students’ enthusiasm and interest in learning, particularly in challenging subjects like physics. This study is expected to offer practical insights for teachers in developing more interactive and effective communication strategies to improve student learning outcomes.

Abstract

Pengabdian Kepada Masyarakat (PKM) ini bertujuan untuk memberikan pemahaman kepada Leton Coffe, sebuah usaha mikro kecil menengah (UMKM) di bidang minuman berbahan dasar kopi, mengenai Perhitungan Aset Tetap dan Penyusutannya. Tim PKM melakukan pendekatan melalui diskusi dengan pihak pengelola Leton Coffe dan studi kepustakaan untuk memperoleh data dan informasi yang relevan. Hasil awal menunjukkan bahwa sistem perhitungan aset tetap dan penyusutannya belum mencerminkan kondisi yang sebenarnya, dikarenakan kurangnya pengetahuan pihak pengelola terkait laporan keuangan terutama dalam hal aset tetap. Dalam pelaksanaan PKM, tim memberikan materi dan pelatihan mengenai cara melakukan perhitungan aset tetap dan penyusutannya. Hal ini diimplementasikan dengan melakukan perhitungan ulang terhadap daftar aset tetap yang ada, memisahkan aset tetap dengan aset lain, dan mengestimasikan penyusutan berdasarkan masa manfaatnya. Hasil perhitungan menunjukkan bahwa nilai total aset tetap Leton Coffe adalah Rp 261.522.400 dengan rata-rata penyusutan tahunan sebesar 25%. Penyusutan untuk tahun 2022 diperkirakan sebesar Rp 65.380.000. PKM ini memberikan manfaat yang signifikan bagi Leton Coffe karena memberikan pemahaman baru mengenai perhitungan aset tetap dan penyusutannya. Dengan adanya pemahaman ini, diharapkan Leton Coffe dapat memperbaiki sistem perhitungan dan laporan keuangannya agar lebih akurat dan sesuai dengan kondisi yang sebenarnya. Saran dari PKM ini adalah pentingnya Leton Coffe untuk terus meningkatkan pemahaman dan pengetahuan terkait laporan keuangan, terutama dalam hal perhitungan aset tetap dan penyusutannya. Dengan pemahaman yang baik, Leton Coffe dapat mengelola aset tetap dengan lebih efisien dan akurat, sehingga berdampak positif pada kinerja keuangan dan pengelolaan usahanya secara keseluruhan.
