Abstract

This study produced biodiesel from Malapari seed oil (Pongamia pinnata L.) by optimizing the esterification and transesterification processes. The objectives of this study were to determine the sulfuric acid (H2SO4) catalyst concentration in the esterification reaction that can reduc the free fatty acid (FFA) content of the seed oil to ≤2%, analyze the oil to methanol molar ratio (i.e.,1:6, 1:9, and 1:12) and KOH concentration (i.e.,2%, 4%, and 6%) that will produce the highest biodiesel yield, and evaluate the quality of the produced biodiesel according to the Indonesian National Standar (SNI) 04-7182-2015. The research was conducted from October to December 2023 at the Plant Physiology Laboratory and the Physical Chemistry Laboratory, FMIPA, UNUD. The research applied Completely randomized design. Quantitative biodiesel data were analyzed using Analysis of Variance. If significant differences (α < 0.05) were detected, then the quantitative biodiesel data were further analyzed using Duncan's Post Hoc Test. Results showed that an H2SO4 concentration of 7% reduced the FFA content to 1.915%. A molar ratio of 1:12 with a 2% KOH catalyst produced the highest biodiesel yield of 65.35%. The produced met the SNI for the saponification number (i.e., 52.82–133.69 mg-KOH/g), iodine number (i.e.,7.19–22.42 g_I2/100_g), and cetane number (i.e., 86.48–132.68). However, the water content (i.e., 0.721%–2.407%), viscosity (i.e., 1.73–6.18 mm²/s), acid number (i.e., 0.224–4.685 mg_KOH/g), density (i.e., 874–917 kg/m³), FFA content (i.e., 0.116 -% to 2.229%), and methyl ester content (48,13% to–132.12%_mass) partially did not meet the standards. This study highlights the potential of Malapari seed oil as a biodiesel feedstock, with further required needed to meet all quality standards.

Abstract

Indonesia’s energy sector continues to face persistent challenges in the context of rapid economic growth, increasing energy demand, and mounting environmental concerns. Despite the constitutional mandate requiring the state to ensure equitable access to energy and sustainability, existing regulatory frameworks frequently fall short of achieving these objectives. This research aims to examine the legal and policy frameworks governing the energy sector in Indonesia, where energy serves as a critical component of economic development and public welfare.The urgency of this study lies in addressing the disconnect between the normative ideals (das Sollen) of equitable and sustainable energy governance and their actual implementation (das Sein) in current policy practices. The research employs a normative legal method, relying on a literature review of both primary and secondary legal sources, coupled with conceptual and statutory interpretation.The findings indicate that current policies often fail to ensure equitable distribution, meaningful public participation, and adequate environmental protection. Accordingly, legal reforms are necessary to advance justice in energy access and to establish enforceable emission limits and environmental standards. The conclusion drawn from this study underscores the importance of bridging the gap between normative aspirations and practical realities in order to achieve inclusive, sustainable, and just energy governance.

Abstract

Kentang (Solanum tuberosum L.) adalah salah satu komoditi pangan penting di dunia. Penyediaan benih kentang generasi awal yang bebas penyakit sistemik virus merupakan masalah utama dalam pembudidayaan kentang. Produksi benih kentang generasi awal berupa umbi mini di rumah kaca masih memiliki resiko kontaminasi oleh penyakit virus. Teknik produksi umbi mikro secara in vitro dapat menjadi metode alternatif untuk produksi benih sumber. Tujuan penelitian ini adalah untuk menentukan media yang optimum dalam produksi umbi mikro pada empat genotipe kentang, yaitu AOTX98202-1RU, ATX9202-3RU, ATTX98468-5R/Y dan ATTX98518-5P/Y. Keempat genotipe dikulturkan pada media Murashige and Skoog (MS) dengan tambahan 6% sukrosa, dengan atau tanpa 2 g L-1 phytagel, dan dengan atau tanpa 10 mg L-1 kinetin. Stek dua buku dikulturkan pada tiap botol kultur, masing – masing dengan lima ulangan. Kultur diinkubasi selama dua minggu pada suhu 23°C dengan fotoperiode 16 jam terang/hari, lalu suhu 16 °C selama 2 minggu dengan fotoperiode 16 jam terang/hari, dan suhu 16 °C dalam ruang gelap selama 6 minggu, dan diamati selama 10 minggu. Hasil penelitian menunjukkan bahwa tiap genotipe memiliki respon yang berbeda terhadap media. Perlakuan 2 g L-1 phytagel + 10 mg L-1 kinetin (T4) merupakan media yang efektif untuk mendorong pertumbuhan umbi mikro pada genotipe ATTX98468-5R/Y dan ATTX98518-5P/Y. Genotipe ATTX98468-5R/Y pada media T4 menghasilkan umbi mikro terbanyak (4.2 umbi mikro/botol), sedangkan ATTX98518-5P/Y menghasilkan rata-rata berat umbi tertinggi (363.6 mg). Hasil penelitian menunjukkan pentingnya untuk mengembangkan protokol khusus untuk tiap genotipe agar mendapatkan produksi umbi mikro yang optimal.
