Abstract

Kitosan merupakan biopolimer hasil deasetilasi kitin yang banyak dimanfaatkan pada berbagai bidang karena bersifat biodegradable dan biokompatibel. Namun, proses deasetilasi konvensional cenderung memerlukan kondisi operasi yang ekstrim sehingga berpotensi menyebabkan degradasi rantai polimer dan penurunan yield kitosan. Penelitian ini bertujuan untuk mengoptimasi proses deasetilasi kitin berbasis microwave guna memperoleh kitosan dengan derajat deasetilasi (DD) ≥ 75% dan degradasi massa yang minimal. Optimasi dilakukan secara simultan terhadap beberapa parameter proses, meliputi konsentrasi NaOH (40–70% b/v), suhu reaksi (60–80 °C), daya microwave (300–600 W), dan rasio pelarut NaOH:kitin (1:10–1:20 b/v). Derajat deasetilasi ditentukan menggunakan analisis FTIR, sedangkan yield kitosan dihitung berdasarkan perbandingan massa kitosan kering terhadap massa awal kitin. Hasil penelitian menunjukkan bahwa peningkatan intensitas kondisi proses mampu meningkatkan derajat deasetilasi, namun secara bersamaan menurunkan yield kitosan akibat degradasi rantai polimer. Kondisi optimum diperoleh pada konsentrasi NaOH 60% (b/v), suhu 70 °C, daya microwave 450 W, dan rasio NaOH:kitin 1:15 (b/v), yang menghasilkan kitosan dengan derajat deasetilasi ≥ 75% dan yield sekitar 70%. Hasil ini menunjukkan bahwa optimasi simultan parameter proses efektif dalam menghasilkan kitosan bermutu tinggi dengan efisiensi proses yang baik.

Abstract

Program pengabdian kepada masyarakat ini bertujuan untuk memperkuat produk unggulan Desa Eduwisata-Preneur di Padukuhan Kroco, Sendangsari, Kulon Progo melalui pelatihan inovasi proses produksi sirup alang-alang. Selama ini, kelompok Kelompok Usaha Peningkatan Pendapatan Keluarga Akseptor (UPPKA) telah memproduksi sirup alang-alang sebagai salah satu produk olahan lokal. Namun, produk tersebut memiliki keterbatasan daya simpan sehingga mengurangi nilai jual dan keberlanjutan usaha. Kegiatan pelatihan menghadirkan narasumber yang memberikan pengetahuan dan keterampilan praktis kepada masyarakat, khususnya anggota UPPKA, mengenai teknik pengolahan dan pengemasan sirup alang-alang agar lebih tahan lama. Metode pelaksanaan meliputi penyuluhan, demonstrasi proses produksi, serta praktik langsung oleh peserta. Hasil kegiatan menunjukkan meningkatnya pemahaman dan keterampilan peserta dalam mengolah sirup alang-alang dengan teknik yang lebih higienis dan mampu memperpanjang masa simpan produk. Dengan adanya inovasi ini, diharapkan sirup alang-alang dapat menjadi produk unggulan yang berdaya saing, mendukung pemberdayaan masyarakat, serta memperkuat identitas Desa Eduwisata-Preneur.

Abstract

Introduction: Early life skills education has the potential to be an effective intervention in preventing adolescent dating violence (ADV). However, measurement tools for life skills in general in the context of ADV prevention are still limited. Objective: This study aims to evaluate the psychometric properties of the General Life Skills Scale (GLSS) using the Rasch model. Methods: This study is classified as research and development. A total of 366 junior high school students (111 students from private schools and 255 students from public schools) in Indonesia participated in the empirical validation of the General Life Skills Scale (GLSS). The GLSS consists of 48 items spread across the constructs of personal skills (22 items) and social skills (26 items). GLSS used a four-point Likert scale, from 1 (strongly disagree) to 4 (strongly agree). The psychometric properties of the GLSS were evaluated using Rasch modeling. The psychometric properties were reviewed based on reliability, item fit, unidimensionality, and item distribution at each level of difficulty. Results: The results of the analysis showed that the GLSS had excellent reliability (? = 0.96; person reliability = 0.93; item reliability = 0.95). The separation index showed the scale's ability to distinguish respondents in five ability strata and items in six difficulty levels. Of the 48 items, 26 items met the Rasch model fit criteria, and unidimensionality analysis confirmed that the scale measured one main construct. However, the Wright map showed logit gaps between items, especially at the very easy difficulty level. Conclusion: The GLSS is considered valid and reliable for measuring adolescents' life skills in the context of preventing dating violence; however, improvements in item distribution are recommended to enhance measurement accuracy. Theoretically, this study contributes to the development of a general life skills scale in adolescent development theory. Practically, this study provides a validated scale for educators to design life skills curricula and can be integrated into school-based ADV prevention programs.

Abstract

Masalah dalam penelitian ini adalah apakah pengaruh proporsi komisaris independen, komite audit, kepemilikan institusional, kepemilikan manajerial, dan leverage terhadap manajemen laba. Tujuan dari penelitian ini adalah untuk menguji dan mendapatkan bukti empiris dari proporsi komisaris independen, komite audit, kepemilikan institusional, kepemilikan manajerial, dan leverage pada manajemen laba. Manfaat penelitian ini diharapkan dapat memberikan manfaat praktis, teoritis, dan kebijakan. Objek penelitian ini adalah sub sektor perusahaan manufaktur perusahaan makanan dan minuman yang terdaftar di Bursa Efek Indonesia pada tahun 2014-2016. Penelitian ini menggunakan metode purposive sampling dalam menentukan jumlah sampel yang digunakan dan diperoleh 11 perusahaan yang dijadikan sampel dalam penelitian ini. Hasil penelitian menunjukkan bahwa proporsi komisaris independen tidak berpengaruh signifikan terhadap manajemen laba. Komite audit memiliki pengaruh negatif yang signifikan terhadap manajemen laba. Kepemilikan institusional tidak berpengaruh signifikan terhadap manajemen laba. Kepemilikan manajerial memiliki pengaruh positif signifikan terhadap manajemen laba. Leverage memiliki pengaruh positif yang signifikan terhadap manajemen laba.

Abstract

A surrogate mother is a woman who agrees to carry a child for a married couple in exchange for compensation. The practice of surrogacy occurs in various countries around the world, both openly and secretly. The purpose of this study is to analyze the practice of surrogate motherhood from the perspective of radical feminist theory and its regulation in Indonesian legislation. The method used is non-doctrinal, with primary data obtained from interviews with informants selected freely and secondary data. The findings of this paper show that radical feminism criticizes and rejects the practice of surrogacy, which is considered to create destructive divisions among women based on social and economic class. The regulation of surrogacy in Indonesian legislation includes the Health Law of 2009 (Amendment 2023), which has not yet been regulated, the MUI fatwa, which prohibits it, and civil law, which considers surrogacy agreements invalid. This article is expected to provide women with a perspective on the practice of surrogacy, which is not always a way out of economic problems, and on the fact that Indonesian legislation does not yet have a strong legal basis for regulating the practice of surrogacy. his study highlights the structural vulnerability experienced by surrogate mothers within patriarchal and capitalist frameworks. It also emphasizes the urgency of establishing clearer and more comprehensive legal regulations to ensure the protection of women’s rights and the legal status of children born through surrogacy practices in Indonesia.
