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: Evaluasi Teknologi Proses Produksi Crude Palm Oil (CPO) dan Red Palm Oil (RPO) Skala Miniplant
Abstrak: Evaluasi Teknologi Proses Produksi Crude Palm Oil (CPO) dan Red Palm Oil (RPO) Skala Miniplant. Dibimbing oleh Farah Fahma. Pengolahan tandan buah segar (TBS) kelapa sawit menjadi minyak sawit dan produk turunannya biasanya dilakukan pada pabrik kelapa sawit (PKS). PKS umumnya dibangun jauh dari perkebunan sehingga banyak TBS yang rusak akibat proses pengangkutan.Tujuan penelitian adalah mengevaluasi teknologi proses produksi minyak sawit untuk produksi skala miniplant. 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 solusi pendirian miniplant sawit dengan kapasitas 1 ton/jam yang beroperasi selama 10 jam/hari dengan memproduksi Crude palm oil (CPO), Red Palm Oil (RPO) dan Palm Kernel (PK). Proses pengolahan CPO dilakukan dengan sterilisasi menggunakan sterilizer vertikal, threshing dengan metode bantingan, digesting dengan penggerusan, ekstraksi menggunakan screw press, klarifikasi menggunakan vibrating screen, vertical clarifier tank (VCT), dan vacuum dryer serta penyimpanan menggunakan sistem pemanasan dan pengadukan. Pengolahan RPO menggunakan proses degumming dengan acid degumming, netralisasi dengan deasidifikasi, dan deodorisasi menggunakan stripping agent. Neraca massa pengolahan kelapa sawit skala miniplant menghasilkan CPO sebanyak 2191 Kg, RPO sebanyak 418,36 Kg, dan PK sebanyak 486,62 Kg. Kata kunci : miniplant sawit, palm oil, teknologi proses, Evaluation of Crude Palm Oil (CPO) and Red Palm Oil (RPO) Production Process Technology On Miniplant Scale. Supervised by Farah Fahma. Processing of fresh fruit bunches (FFB) of oil palm into palm oil and its derivative products is usually carried out at palm oil mills (PKS). PKS are generally built far from the plantations so that a lot of FFB is damaged due to the transportation process. The aim of this research is to evaluate the technology of palm oil production process for miniplant scale production. The research method used 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 were in the form of providing a solution for establishing a palm oil miniplant with a capacity of 1 ton/hour which operates for 10 hours/day that produces Crude Palm Oil (CPO), Red Palm Oil (RPO) and Palm Kernel (PK). The CPO processing process was carried out by sterilization using a sterilizer vertical, threshing with the slamming method, digesting by grinding, extraction using a screw press, clarification using a vibrating screen, vertical clarifier tank (VCT), and vacuum dryer and storage using a heating and stirring system. RPO processing used degumming with acid degumming, neutralization by deacidification, and deodorization using stripping agent. The mass balance of miniplant-scale palm oil processing resulted in 2191 Kg of CPO, 418.36 Kg of RPO, and 486.62 Kg of PK. Keywords: palm miniplant, palm oil, process technology

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
