Abstract

Shallots (Allium cepa L.) are a horticultural commodity with high economic value and widespread consumption. This study aimed to evaluate the effect of cow manure and liquid organic fertilizer (LOF) made from chicken eggshells on the growth and yield of shallots. The study was conducted at the experimental garden and Plant Physiology Laboratory, Faculty of Agriculture, Malikussaleh University, from November 2024 to February 2025. The experiment was arranged using a two-factorial Randomized Block Design (RBD) with three replications. The first factor was the dose of cow manure (0, 40, and 80 g polybag⁻¹), while the second factor was the concentration of chicken eggshell POC (0, 50, and 100 mL L⁻¹ water). The results showed that cow manure significantly affected plant height at 2 weeks after planting (WAP), root weight and volume, fresh and dry tuber weight per clump, and yield, with the best response at a dose of 40 g polybag⁻¹. Chicken eggshell LOF significantly affected plant height at 4 weeks post-plant growth (WAP), root length and volume, root weight, fresh and dry tuber weight, and yield, with the highest value at a concentration of 100 mL L⁻¹ of water. The interaction of the two treatments significantly affected root weight and volume, with the best combination at a dose of 80 g cow manure per polybag⁻¹. The combination of cow manure and chicken eggshell POC has been shown to increase shallot growth and yield.

Abstract

Indonesia faces crucial challenges in energy security due to the increasingly alarming decline in oil reserves from around 3.6 billion barrels in 2000 to less than 2.5 billion barrels in 2023, while dependence on oil imports continues to burden the national energy balance and economy. Amid unstable global geopolitical conditions, including the Russia-Ukraine war and tensions in the Middle East that have caused fluctuating energy prices, the transition to local and sustainable energy sources has become a strategic priority. The Indonesian government has affirmed its commitment to achieving net-zero emissions by 2060 through various energy transition policies, including the development of renewable gas and the utilization of waste as an energy source. One of the major potentials that has not been optimally utilized is palm oil mill effluent (POME), which annually produces more than 500 million tons throughout Indonesia. POME contains a high concentration of organic matter that can be processed through anaerobic digestion to produce biogas, which is then purified and compressed into Bio-Compact Natural Gas (Bio-CNG). This study analyzes the potential of Bio-CNG technology from POME in three main dimensions: (1) conversion and storage technology, (2) economic analysis and feasibility of scale implementation at the palm oil mill level, and (3) its contribution to reducing GHG emissions and diversifying national energy. The study results show that by utilizing 70% of the total annual POME, the potential for Bio-CNG production reaches over 3.5 billion m³/year, equivalent to over 25% of current domestic natural gas consumption. Furthermore, the application of this technology can reduce CH3 emissions.₄from POME waste up to 80% and contributes significantly to the target of renewable energy (EBT) mix of 23% in 2025 and net zero in 2060. Economically, Bio-CNG shows competitive production costs (Rp25,000–35,000/m³) compared to industrial gas prices, especially with the presence of carbon incentives and carbon pricing mechanisms that are being developed. This study concludes that converting POME into Bio-CNG is not only a green technology solution but also a crucial energy security and climate mitigation strategy amidst uncertain global energy supplies and international decarbonization pressures. Policy recommendations include tax incentives, integration into the national gas grid, and mandatory regulation of waste energy utilization for the palm oil industry.

Abstract

This academic review comprehensively analyzes the development of bio-oil refining technology from the pyrolysis of mixed plastic and biomass waste, focusing on its characteristics, technical challenges, and application prospects in Indonesia. Mixed bio-oil has a complex composition influenced by radical interactions during pyrolysis, resulting in high-value hydrocarbon fractions but still containing oxygenated compounds that reduce fuel stability and quality. This study examines the effectiveness of major refining methods, including hydrodeoxygenation (HDO), catalytic cracking, and integrated co-pyrolysis, and assesses the performance of latest generation catalysts such as NiMo/Al₂O₃ and ZSM-5, which demonstrate significant selectivity and reaction stability. The analysis also identifies obstacles to industrial-scale implementation, such as catalyst deactivation, high hydrogen requirements, feedstock variability, and high operating costs. In the Indonesian context, the potential for application of this technology is significant due to the abundance of biomass and plastic waste, coupled with renewable energy policies that support diversification of energy sources. This review emphasizes the need for research integration, process optimization, infrastructure capacity building, and collaboration between government, industry, and academia to accelerate the development of efficient, economical, and sustainable bio-oil refining technology.

Abstract

This study analyzes the implementation of the mandatory biodiesel policy in Indonesia, focusing on the dynamics of catalyst research, feedstock diversification, and industry responses in the context of the national energy transition. The mandatory policy, which began with B10 in 2016 and increased to B35 in 2023, aims to reduce dependence on fossil fuels by utilizing the potential of palm oil as the world's largest producer. Using a qualitative approach with a case study design, the research was conducted in four provinces: West Java, East Java, North Sumatra, and Riau over eight months, involving 35 informants from researchers, policymakers, and industry players. Data were collected through in-depth interviews, field observations, and documentation studies, analyzed using thematic analysis methods. The results show that biodiesel catalyst research has made significant progress in utilizing local materials such as rice husk ash and eggshells, but faces a large gap between laboratory success and industrial implementation due to minimal collaboration and funding for applied research. Feedstock diversification is still hampered by the dominance of palm oil, which reaches 95 percent, while alternatives such as castor oil, animal fats, and microalgae are not yet economically competitive. The industry's response to the mandatory policy is polarized, with large, vertically integrated companies able to adapt through technology investment and capacity expansion, while small and medium-sized producers face structural constraints such as limited capital, access to raw materials, and weak bargaining power. The misalignment between ambitious policy targets, limited technological readiness, and uneven industrial capacity creates an implementation gap that hinders the achievement of a sustainable energy transition. The study recommends establishing a research-industry collaboration platform, strengthening feedstock diversification policies, empowering small and medium-sized producers, conducting public education campaigns, and cross-ministerial coordination through a dedicated energy transition agency to develop a realistic and coordinated long-term roadmap.

Abstract

Pertumbuhan kebutuhan energi global yang masih bergantung pada bahan bakar fosil menuntut pengembangan sumber energi terbarukan yang berkelanjutan. Biomassa lignoselulosa, khususnya rumput gajah (Pennisetum purpureum), memiliki potensi besar sebagai bahan bakar alternatif, namun memiliki keterbatasan seperti densitas energi rendah dan kadar air tinggi. Penelitian ini mengevaluasi peningkatan sifat fisik dan kimia bio-coal dari rumput gajah melalui proses torrefaksi menggunakan retort kiln.  Metode yang digunakan mencakup torrefaksi pada suhu 225°C dan 275°C dengan waktu tinggal 30 menit, menggunakan sampel biomassa kering seberat 5 kg. Karakterisasi produk dilakukan melalui analisis proksimat (ASTM E1756-01) dan pengukuran nilai kalor tertinggi (HHV) dengan bomb calorimeter (ASTM D5865), serta perhitungan rendemen massa dan rendemen energi.  Hasil menunjukkan bahwa torrefaksi secara signifikan menurunkan kadar air dan zat terbang, serta meningkatkan kadar karbon tetap dan nilai kalor tertinggi (HHV) bio-coal, dari 15,26 MJ/kg menjadi 19,97 MJ/kg dan 21,75 MJ/kg secara berturut-turut. Rendemen massa tercatat sebesar 40%, sementara rendemen energi mencapai 52,36% pada 225°C dan 57,02% pada 275°C, menunjukkan efisiensi konversi energi yang baik meskipun terjadi kehilangan massa. Profil temperatur stabil selama proses torrefaksi memastikan homogenitas produk. Temuan ini menegaskan bahwa retort kiln efektif dalam menghasilkan bio-coal berkualitas tinggi dari rumput gajah, memberikan kontribusi penting bagi pengembangan teknologi bahan bakar padat terbarukan skala industri.
