Abstract

The development of environmentally friendly propellant technology has become a primary focus in the defense industry. Composite propellants, which have traditionally relied on Ammonium Perchlorate (AP), offer high performance but pose environmental concerns due to the emission of corrosive chlorine compounds. This study aims to evaluate the potential use of green oxidizers such as Ammonium Dinitramide (ADN), Hydrazinium Nitroformate (HNF), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) as alternatives to AP. A qualitative literature review method was employed, drawing from various national and international scientific sources. Findings show that ADN and HNF offer promising performance and are more eco-friendly due to no chlorine emissions. However, challenges like thermal stability, hygroscopicity, and high production costs remain. This research highlights the potential of green oxidizers to reduce pollution and enhance national defense industry sustainability.

Abstract

Pada desain sistem pengering supaya mendapatkan desain dengan kinerja efisiensi tinggi memerlukan lebih banyak biaya dan waktu karena terdapat banyak variabel yang perlu diperhitungkan. Untuk mengatasi masalah ini, penelitian ini melakukan simulasi distribusi suhu di ruang pengering menggunakan metode CFD. Ruang pengering akan dianalisis menggunakan 3 skenario geometri yaitu kotak (balok), bulat (tabung), dan poligon (prisma). Pada dasarnya, perbedaan dalam skenario ke-1 hingga ke-3 adalah dalam posisi geometri dan kipas inlet, sedangkan komponen dan dimensi (volume) dari ruang pengering dibuat sama sehingga data yang diperoleh lebih valid. Hasil simulasi skenario 1 mendapatkan suhu rata-rata 39,08 °C, hasil simulasi skenario 2 mendapatkan suhu rata-rata 38,98 °C, hasil simulasi skenario 3 mendapatkan suhu rata-rata 34,77 °C sehingga disimpulkan bahwa simulasi suhu paling seragam berada di skenario 2 dengan ruang pengering bulat.

Abstract

Koi (Cyprinus rubrofuscus Lacepede, 1803) is a highly favored ornamental fish due to its beauty and wide range of variations in Indonesia, categorized by color, patterns, and scales. Some variants are distinguished by color, while others, such as Ginrin, Doitsu, and Shusui, have unique scale types. Despite visible differences, microscopic scale variations remain unexplored. SEM studies in other fish species offer insights into scale ultrastructure, providing opportunities for comparison. Therefore, this study aimed to uncover the microscopic structure of four types of koi fish, namely Doitsu, Ginrin, Shusui, and common scale. Koi fish were obtained from breeders in Yogyakarta, Indonesia, and acclimatized in an aquarium. Scale extraction was conducted under anesthesia using MS-222 and the cleaned scales were then subjected to dehydration, fixation, and affixed to double-sided adhesive tape for SEM analysis. Furthermore, coating with conductive gold enabled observation using SEM at 10 kV, allowing examination of scale features such as focus, radii, circuli, and lepidonts at various magnifications. The results showed that based on SEM analysis, significant differences were observed in scale structures among koi variants. At low magnification, differences in tubercles and lepidonts were observed, particularly between common and Ginrin scale types. Shusui scale showed unique characteristics with a closer arrangement of circuli and distinctive lepidont shapes. At higher magnification, clearer details of radii, circuli, and lepidonts were observed, further highlighting the differences among koi variants. SEM provides crucial insights into the morphology of scales in koi fish variants, showing unseen macroscopic differences and distinct features such as tubercles and lepidont frequency.

Abstract

Equine mesenchymal stem cells (MSCs) are promising for bone tissue engineering (BTE) because of their capabilities of differentiating into osteoblasts. Cell therapy using equine MSCs has been introduced. Recently, dental-derived MSCs have gained significant attention due to their capabilities and ease of collection with minimally invasive collection methods. Dental stem cells show high plasticity, accessibility, and applicability for regenerative medicine and are thus considered alternative sources of MSCs. This study evaluated the characterization, osteogenic differentiation potential, and migration assay of equine dental pulp stem cells (eDPSCs) as compared with equine periodontal ligament stem cells (ePDLSCs). Equine dental stem cells from eDPSCs and ePDLSCs (n = 4) were isolated and expanded to passage 3. The morphology, colony-forming capability, cell proliferation assay, stemness and surface markers, trilineage differentiation potential, and migration assay were investigated in vitro. Both eDPSCs and ePDLSCs exhibited a fibroblast-like morphology; showed a colony-forming capability; were able to proliferate based on the results of the cell proliferation assay; expressed stemness and surface markers (NANOG, CD29, CD44, CD90, CD18); maintained the ability to differentiate into osteocytes, chondrocytes, and adipocytes and demonstrated migration capacity based on the migration assay. Surprisingly, ePDLSCs showed significant differences in matrix mineralization, quantification of Alizarin Red staining by cetylpyridinium chloride, and mRNA expression of the osteogenic marker RUNX2. ePDLSCs and eDPSCs may be better alternative MSCs than dental stem cells for the further design of therapeutic regimens for BTE and wound-healing therapy.

Abstract

Indonesia aims for 23% renewable energy by 2025 and a 29% reduction in greenhouse gas emissions by 2030 under the Paris Agreement. B35 biodiesel, a blend of 35% palm oil-based biodiesel and 65% diesel, is a key strategic solution for this energy transition. This study, using a mixed method approach with regression analysis, analyzed data from the Ministry of Energy and Mineral Resources and Indonesian palm oil industry reports. It aimed to quantify B35's contribution to the renewable energy mix and project outcomes for a potential B40 policy. An in-depth analysis was conducted to identify the success factors and challenges of biodiesel implementation. Results show B35 biodiesel significantly contributes to Indonesia's renewable energy goals, reaching 38% in 2023 and 38.75% in 2024. Its implementation also led to substantial savings of IDR 120.54 trillion in 2023 and IDR 123 trillion in 2024 by substituting fossil fuel imports. Regression projections suggest that B40 biodiesel could further increase renewable energy contributions to 40.7% with a 15.62 million kL production target in 2025. Additionally, biodiesel usage reduces CO₂ emissions by 8-11% compared to conventional diesel. In conclusion, B35 biodiesel plays a vital role, contributing nearly 40% to Indonesia's national renewable energy. For successful B40 implementation and to optimize biodiesel's role in achieving 2025 targets, a stable Crude Palm Oil (CPO) supply, a USD 4.1 billion infrastructure investment, consistent policy frameworks, feedstock diversification, carbon tax implementation, and strong inter-ministerial collaboration are essential.

Abstract

Virus avian influenza (AI) merupakan virus dengan materi genetik RNA single-stranded sense negatif, beramplop yang termasuk dalamfamili Orthomyxoviridae. Onestep simplex reverse transcriptase-polymerase chain reaction (RT-PCR) merupakan salah satu metode diagnosis yang dapat diandalkan untuk mendeteksi virus AI. Tujuan dari penelitian ini adalah untuk menerapkan metode diagnosis cepat virus AI pada spesimen lapangan secara langsung dari pasar unggas berdasarkan amplifikasi RT-PCR gen M dan H5 dengan metode yang berbasis onestep simplex RT-PCR tanpa melalui proses inokulasi dan propagasi virus AI dalam telur ayam berembrio (TAB). Sebanyak 35 sampel spesimen lapangan dari swab trakea unggas yang berasal dari pasar unggas di Terban, Kotamadya Yogyakarta digunakan dalam penelitian ini. Amplifikasi DNA secara onestep simplex RT-PCR pada gen matriks (M) dilakukan terhadap seluruh sampel. Pada sampel-sampel yang menunjukkan hasilpositif pada amplifikasi gen M kemudian dilakukan amplifikasi RT-PCR secara lebih lanjut untuk gen H5 virus AI. Produk hasil amplifikasi RT-PCR gen M dan H5 divisualisasikan menggunakan elektroforesis gel agarose konsentrasi 1% dengan pewarnaan SYBRSafe DNA Gel Staining. Hasil amplifikasi RT-PCR gen M menunjukkan bahwa dari 35 sampel diperoleh 8 sampel positif terinfeksi virus AI tipe A yang ditunjukkan dengan adanya fragmen DNA sebesar 200 bp, sedangkan hasil amplifikasi gen H5 sebanyak 5 dari 8 sampel-sampel tersebut merupakan virus AI tipe A subtipe H5 yang ditunjukkan dengan adanya fragmen DNA sebesar 545 bp. Diagnosis cepat virus AI tipe A subtipe H5 secara langsung dari spesimen lapangan di pasar unggas dapat dilakukan dengan metode onestep simplex RT-PCR, namun metode diagnosis tersebut tidak dapat mendeteksi keberadaan virus AI dalam sampel yang virusnya terlalu sedikit.
