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: Inovasi Penggunaan Bahan Baku dan Teknologi Sterilizer Pengolahan Crude Palm Oil (CPO) pada Pabrik Kelapa Sawit Skala Miniplant
Abstrak: Indonesia merupakan penghasil kelapa sawit terbesar di dunia. Hasil pengolahan kelapa sawit berupa minyak sawit yang merupakan komoditas ekspor utama yang memiliki banyak manfaat serta berpotensi meningkatkan perekonomian Indonesia. Bahan baku yang digunakan untuk pengolahan kelapa sawit berupa tandan buah segar (TBS). Faktanya, buah yang terlepas dari tandan berpotensi sebagai bahan baku. Proses pengolahan kelapa sawit juga menjadi penentu keberhasilan proses untuk menghasilkan minyak sawit berkualitas. Tujuan penelitian adalah memanfaatkan buah brondolan sebagai bahan baku dan mengembangkan inovasi teknologi sterilisasi pengolahan Crude Palm Oil (CPO). 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 berupa pemberian alternatif bahan baku yang potensial dalam pengolahan Crude Palm Oil (CPO) dan inovasi teknologi proses sterilisasi dengan melakukan penambahan air sebelum proses sterilisasi berlangsung serta menggunakan auger pada sterilizer untuk mempermudah proses pengeluaran bahan baku sehingga proses berjalan efektif dan efisien., Indonesia is the largest producer of palm oil in the world. Palm oil processing results in the form of palm oil which is the main export commodity that has many benefits and has the potential to improve the Indonesian economy. The raw material used for processing palm oil is in the form of fresh fruit bunches (FFB). In fact, the fruit that is separated from the bunch also has the potential as a raw material. The palm oil processing process is also a determinant of the success of the process to produce quality palm oil. The purpose of this research is to utilize loose fruit as raw material and to develop innovative processing sterilization technology innovations Crude Palm Oil (CPO). 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 the provision of potential alternative raw materials in the processing of Crude Palm Oil (CPO) and technological innovation of the sterilization process by adding water before the sterilization process takes place and using an auger on the sterilizer to facilitate the process of releasing raw materials so that the process runs effectively and efficiently.

Judul: Dynamical System of Hepatitis B in Three Groups with Vaccination
Abstrak: The aim of this study is to modify the hepatitis B transmission model in three age groups involving vaccination from the model conducted by Zhoe and Zhang.The method used is to analyze the stability of the fixed point and its basic reproduction number (R_0). Performed stability analysis and numerical simulation to see population dynamics. Next, a sensitivity analysis of the parameters was carried out to see its effect on R_0. From the analysis obtained two fixed points, namely non-endemic and endemic fixed points. Non-endemic fixed points are locally asymptotically stable if R_0 <1 Meanwhile, the endemic fixed point is locally asymptotically stable if R_0 > 1. Hepatitis vaccination affects the number of susceptible population, because the more successful the vaccination, the smaller the number of susceptible populations so that the smaller the population will be infected.
