Judul: Circular Economy Concept Design to
Support the Sustainability of the Palm Oil Industry
Abstrak: Agroindustri kelapa sawit di Indonesia terus mengalami peningkatan produktivitas yang berdampak pada tingginya produk samping dan limbah yang dihasilkan. Ketidakefektifan pengolahan limbah menuntut adanya penanganan yang lebih efisien dan berkelanjutan untuk mengurangi dampak buruk serta memaksimalkan nilai ekonomis dari limbah. Konsep penanganan limbah dapat didukung dengan penerapan ekonomi sirkular, yang tidak hanya mengurangi beban lingkungan tetapi juga memberikan manfaat ekonomi melalui penghematan energi dan bahan baku. Rancangan proses penanganan limbah yang diusulkan mencakup proses pirolisis pada suhu 300, Palm oil agroindustry in Indonesia continues to experience increased productivity, leading to higher by-products and waste generation. Ineffectiveness in waste processing necessitates more efficient and sustainable handling to mitigate adverse impacts and maximize economic value from waste. The waste management concept can be supported by implementing a circular economy approach, which not only reduces environmental burdens but also provides economic benefits through energy and raw material savings. The proposed waste management process design includes pyrolysis at 300

Judul: Kajian Produk Turunan Industrial Palm Oil (IPO) dan Pengolahan Limbah pada Pabrik Kelapa Sawit Skala Miniplant
Abstrak: Minyak sawit merupakan komoditas ekspor utama yang memiliki banyak manfaat serta berpotensi meningkatkan perekonomian Indonesia. Pendirian pabrik kelapa sawit skala miniplant mampu meningkatkan pendapatan petani akibat pemangkasan biaya distribusi dan rantai pasok yang panjang. Penelitian ini bertujuan mengkaji produk Indusrial Palm Oil (IPO) yang potensial untuk di produksi pada pabrik kelapa sawit skala miniplant serta membuat kajian pengolahan limbah yang dihasilkan dari proses pengolahan produk sehingga pabrik yang didirikan dapat beroperasi secara efisien dan menguntungkan serta ramah lingkungan. Metode penelitian menggunakan kombinasi bentuk kualitatif sebagai data primer yang diperoleh dari hasil observasi dan wawancara dan bentuk kuantitatif sebagai data sekunder yang diperoleh melalui studi literatur. Hasil yang diperoleh adalah informasi produk-produk yang potensial untuk diproduksi oleh pabrik skala miniplant yaitu Crude Palm Oil (CPO), Red Palm Oil (RPO), Palm Kernel (PK) dan produk energi (biodiesel dan Pure Plant Oil) dan juga kajian pengolahan dan pemanfaatan limbah cair dan limbah padat dari proses produksi., Oil Palm oil was a major export commodity that has many benefits and has the potential to improve the Indonesian economy. The establishment of a miniplant-scale palm oil mill is able to increase farmers income due to cutting distribution costs and a long supply chain. This study aims to examine Industrial Palm Oil (IPO) potential products to be produced in miniplant scale palm oil mills and to study the processing of waste generated from the product processing so that the established factories can operate efficiently and profitably and are environmentally friendly. The research method uses a combination of qualitative forms as primary data obtained from observations and interviews and quantitative forms as secondary data obtained through literature studies. The results obtained are information on potential products to be produced by miniplant scale factories, namely Crude Palm Oil (CPO), Red Palm Oil (RPO), Palm Kernel (PK) and energy products (biodiesel and Pure Plant Oil) as well as processing studies and utilization of liquid waste and solid waste from the production process.

Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test
