Abstract

Teh menjadi minuman yang biasa dikonsumsi oleh sebagian masyarakat dan salah satu minuman yang banyak dikenal oleh seluruh dunia, yang dihasilkan dari pucuk daun muda tanaman Camellia sinensis. Berdasarkan proses pengolahannya, teh dapat dikategorikan menjadi berbagai jenis, termasuk teh hitam, teh oolong, teh hijau, dan teh putih. Tanaman teh dikenal kaya akan senyawa polifenol, yang memiliki potensi sebagai agen antioksidan dan memberikan berbagai manfaat kesehatan. Penelitian ini bertujuan untuk mengeksplorasi aktivitas antioksidan pada teh celup, yang merupakan produk minuman fungsional yang banyak dikonsumsi masyarakat. Metode yang digunakan dalam penelitian ini adalah DPPH (2,2-difenil-1-pikrilhidrazil), di mana absorbansi dari sampel diukur menggunakan spektrofotometer dengan pendekatan kuantitatif untuk menilai efektivitas antioksidan. Hasil analisis menunjukkan bahwa terdapat peningkatan nilai persen inhibisi, yang mengindikasikan adanya aktivitas antioksidan dalam sampel teh celup. Dari pengukuran tersebut, diperoleh nilai IC50 sebesar 326,542 µg/mL, yang menunjukkan bahwa teh celup memiliki aktivitas antioksidan yang tergolong sangat lemah. Kesimpulan dari penelitian ini menegaskan bahwa meskipun teh celup mengandung senyawa yang memiliki potensi antioksidan, efektivitasnya dalam mengatasi radikal bebas masih rendah, seperti yang ditunjukkan oleh nilai IC50 yang tinggi.

Abstract

Salah satu produk olahan tradisional yang banyak dikonsumsi di Indonesia adalah kerupuk. Kerupuk merupakan salah satu jenis camilan yang banyak disukai oleh masyarakat. Teksturnya yang renyah dan rasa gurih yang dimiliki kerupuk menjadi salah satu faktor yang berpengaruh terhadap penerimaan konsumen. Salah satu produk yang bisa dikembangkan adalah kerupuk maruku chan dari bahan baku tepung ketan dengan selalu memperhatikan kandungan gizinya salah satunya yaitu kadar airnya. Tujuan dari kegiatan ini adalah untuk menguji kadar air pada produk pangan yaitu kerupuk maruku chan. Kegiatan ini menggunakan pendekatan kuatitatif yaitu data berupa angka yang didapatkan secara langsung. Hasil dari kegiatan ini adalah kadar air pada kerupuk maruku chan mengalami kenaikan berat 1 gram karena faktor pemanasan mapun timbangan tersebut. Hal tersebut karena adanya reaksi yang menghasilkan air atau zat yang mudah menguap, seperti dekomposisi gula, karamelisasi, atau oksidasi lemak selama proses pemanasan. Pengujian kadar air pada produk pangan sangat penting karena erat hubungannya dengan penampakan, tekstur, cita rasa, dan keawetan suatu produk. Kesimpulan dari kegiatan ini adalah kadar air pada kerupuk maruku chan mengalami kenaikan bobot 1 gram pada pemanasan kedua selama 1 jam dikarenakan faktor pemanasan, kontaminasi, maupun timbangan tersebut.

Abstract

Keuangan dan perbankan syariah mempunyai landasan mendasar pada wahyu Allah SWT sebagai penciptanya. Dengan demikian, industri keuangan dan perbankan Islam menempati tempat khusus di pasar global kontemporer karena hubungan mendasar antara wahyu dan kesejahteraan umat manusia. Metode penelitian yang digunakan pada penelitian ini menggunakan metode penelitian yuridis normatif dengan pendekatan kasus dan sejarah hukum, Dari segi terminologi, beberapa kalangan mempertanyakan penggunaan istilah “kredit” pada KPR syariah, karena istilah ini cenderung menimbulkan asumsi tentang terjadinya kredit, padahal perbankan syariah tidak menggunakan sistem kredit. Oleh karena itu, beberapa bank syariah, Dari penjelasan yang telah dijelaskan di atas, dapat disimpulkan bahwa kedudukan Kredit Pemilikan Rumah (KPR) dalam perekonomian syariah diperbolehkan. Dalam praktiknya, KPR syariah diawali dengan peralihan kepemilikan rumah dari penjual ke bank. Setelah bank syariah memiliki rumah tersebut, maka bank mempunyai hak dan kewajiban penuh atas rumah yang dibeli tersebut.

Abstract

Financial Technology is financial technology developed for purposes in the financial sector. One type of Financial Technology is Peer-to-Peer (P2P) Lending, which is an information technology-based lending service. Technological innovation has brought a more practical financial transaction process, one of which is applied to online loans. From 2017 to 2023, as many as 7,502 illegal online lending entities were closed by the OJK.

To reduce these cases, the author provides a solution that requires an increasing understanding of digital financial literacy, especially illegal online loans, in society. The aim of this Community Service (PkM) activity is to understand digital financial literacy in the community. The target of this activity is the women of the 'Aisyiyah Ngasem Branch Management, Colomadu District, Karanganyar.

Abstract

This community service aims to provide education and training on the importance of digital financial literacy to the younger generation under the auspices of the Regional Leadership of ‘Aisyiyah (PDA) Karanganyar.The target participants of this program are members of the Aisyiyah School of Entrepreneurship (SWA), consisting of orphaned youth living in the Aisyiyah Girls’ Orphanage dormitory. The challenge faced by PDA Karanganyar itself is the lack of financial literacy education and entrepreneurship training. Therefore, we provide a solution by carrying out community service through education and training for the young generation of SWA. Digital financial literacy is very important to apply in daily life. Advancing technology requires us to adapt to current situations and conditions. With digital financial literacy education for young people, it is expected that they will be able to manage finances wisely, make use of facilities to simplify tasks, avoid impulsive spending, and prevent negative impacts of digital finance such as online loans (pinjol). The method used in this community service is lectures, delivering material related to the benefits and importance of digital financial literacy education for the younger generation. The results of the community service show that participants understood the material presented, as evidenced by their enthusiasm in asking questions and actively participating in discussions. It is hoped that from the results of this community service, participants will be able to apply digital financial literacy in their daily lives and inspire other young people to understand the importance of digital literacy and have the courage to start entrepreneurship. The plan for the next community service program is to provide training on how to maximize promotion through social media, start a business, and utilize affiliate marketing on their social media platforms.

Abstract

This research aims to 1) To determine the partial influence of production factors (Seeds, Fertilizer, Labor and Land Area) on rice production in farming in the Bonder Village farming group, 2) to determine the production results and income from rice farming in the farming group in Bonder Village. The research method uses a quantitative approach by determining the number of respondents using the Slovin formula. Data analysis was carried out using the Cobb-Douglas production function to determine the influence of production factors on farming results, as well as income analysis using the total revenue (TR) and total cost (TC) approaches. The research results show that the average rice production reaches 5,000 kg per hectare, while the average rice farming income is IDR. 26,000,000 per hectare. Simultaneous testing of production factors produces a value of Fcount = 5684.973 with a significance level of 0.000, which means that the production factors together have a significant effect on rice production in Bonder Village. Income analysis shows that rice farming is still worth pursuing because it can provide quite high profits for farmers. Thus, it can be concluded that efficiency in the use of production factors contributes significantly to increasing production and farmer income.
