"Oil palm empty fruit bunch (OPEFB) is one of the waste products of oil palm plantations and has not been optimally used in Riau Province, Sumatera, Indonesia. OPEFB is reduced by incineration, which causes pollution problems. However, the combustion of OPEFB generates ash, which is rich in potassium. Moreover, OPEFB fiber has good strength, low cost, low density, and biodegradability, and it can be used as composite reinforcement. However, the natural fibers in composites have poor compatibility with the matrix and relatively high moisture absorption. Hydrolysis of OPEFB ash creates a base solution that can be utilized in an alkaline treatment process to increase the mechanical properties of natural composites. The aim of this study was to investigate the effect of various extracts of OPEFB ash on the tensile strength, flexural strength, and water absorption of an OPEFB fiber-polypropylene composite. The experimental design used was the Response Surface Method-Central Composite Design (RSM-CCD). The results showed that the tensile strength increased with an increase of fiber length and concentration of the OPEFB ash extract solution, but tensile strength decreased with a longer soaking time. Flexural strength increased with an increase in fiber length but decreased with an increase in the concentration of the OPEFB ash extract solution and longer soaking time. Water absorption increased with lower and higher concentrations of OPEFB ash extract solution and fiber length and with shorter and longer soaking times. The highest tensile strength (20.100 MPa) was achieved at 5%wt alkaline concentration, 36 h soaking time, and 3 cm fiber length. The highest flexural strength (30.216 MPa) was achieved at 5%wt alkaline concentration, 12 h soaking time, and 3 cm fiber length. The lowest water absorption (0.324%) was achieved at 10%wt alkaline concentration, 24 h soaking time, and 2 cm fiber length."

"Tesis ini membahas mengenai tinjauan yuridis pertanggungjawaban Uni Eropa terhadap sengketa kelapa sawit yang terjadi di Indonesia. Metode penelitian yang digunakan merupakan penelitian deskriptif yang bersifat yuridis normatif, yakni mengkaji pelaksanaan atau implementasi ketentuan hukum atau aturan secara faktual pada suatu peristiwa hukum tertentu yang terjadi di dalam masyarakat untuk mencapai tujuan yang ditentukan. Kali ini Indonesia dihadapkan dengan sengketa perdagangan Internasional dengan Uni Eropa yaitu terkait dengan produk kelapa sawit. Uni Eropa dalam kebijakan RED II akan menghentikan pemakaian minyak sawit sebagai bahan bakar nabati pada tahun 2030, karena isu pengrusakkan lingkungan. Hal ini tentu berdampak pada perdagangan Indonesia, terutama dengan adanya penurunan ekspor minyak kelapa sawit atau CPO ke Eropa secara bertahap dari tahun 2021 sampai di hilangkan pada tahun 2030. Hal ini akan mengakibatkan kerugian pada pendapatan negara Indonesia, pengurangan tenaga kerja, stok yang berlebihan, pengurangan devisa negara, dan mengurangi kesejahteraan petani dan pengusaha sawit Indonesia. Berdasarkan hasil penelitian Indonesia telah mengajukan gugatan ke WTO lewat badan penyelesaian sengketa WTO atas tindakan diskriminasi produk kelapa sawit. Kebijakan RED II dianggap telah membatasi akses pasar minyak sawit ke Eropa dengan regulasi dan persyaratan-persyaratannya. Berdasarkan kesimpulan penulisan tesis ini kebijakan RED II telah melanggar ketentuan dalam perjanjian perdagangan internasional, bahwa kebijakan RED II tidak sesuai dengan aturan WTO, khususnya tentang perjanjian Technical Barriers to Trade, dan GATT 1994. Hasil penelitian menyarankan perlunya merevisi atau mengubah kebijakan RED II Uni Eropa untuk menyesuaikan diri dengan perkembangan liberalisasi perdagangan sesuai dengan aturan WTO, sehingga tidak menimbulkan kerugian terhadap produk minyak kelapa sawit dan produk produk lain kedepannya.

This thesis discusses the juridical review of the EU's responsibility for oil palm disputes in Indonesia. The research method used is a descriptive normative juridical study, which examines the factual implementation or implementation of legal provisions or rules on a certain legal event that occurs in society to achieve specified goals. This time Indonesia is faced with an international trade dispute with the European Union, which is related to palm oil products. The European Union in the RED II policy will stop the use of palm oil as a biofuel by 2030, due to issues of environmental destruction. This certainly has an impact on Indonesia's trade, especially with the gradual decline in exports of palm oil or CPO to Europe from 2021 until it is eliminated in 2030. This will result in losses to Indonesia's state income, reduction of labor, excessive stock, reduction of foreign exchange, and reduce the welfare of Indonesian palm oil farmers and entrepreneurs. Based on the results of the research, Indonesia has filed a lawsuit to the WTO through the WTO dispute resolution agency for discrimination against palm oil products. The RED II policy is considered to have limited market access for palm oil to Europe with its regulations and requirements. Based on the conclusion of this thesis, the RED II policy has violated the provisions in the international trade agreement, that the RED II policy is not in accordance with the WTO rules, especially regarding the Technical Barriers to Trade agreement, and GATT 1994. The results of the study suggest the need to revise or change the EU RED II policy to adapt to the development of trade liberalization in accordance with WTO rules, so as not to cause harm to palm oil products and other products in the future."

"In the palm oil refining processes, the free fatty acid content is reduced to an acceptable level by using steam-stripping that causes, also, the loss of nutraceuticals such as tocopherols and carotenoids. An alternative method, such as solvent extraction, to separate free fatty acids, especially palmitic acid as the major free fatty acid present in palm oil, will conserves not only the important nutraceuticals but, also, conserves energy because a steam requirement is eliminated. The objective of this research is to evaluate the performance of Natural Deep Eutectic Solvents (NADES), each consisting of betaine as the hydrogen bonding acceptor and a polyalcohol as the hydrogen bonding donor, to extract palmitic acid from palm oil. The goal is to obtain a NADES that is able to extract palmitic acid from palm oil with the highest extraction yield. The viscosity of various studied NADES was 10-236 cSt while the polarity parameter, determined by using Nile red as the solvatochromic dye, was 48.9-50.8 kcal/mol. The obtained data shows that, for NADES having similar polarity to that of betaine, the extraction yields reduce with increasing viscosity of the NADES. The highest extraction yield of 60% (w/w), corresponding to a distribution coefficient value of 0.75, was obtained by using NADES consisting of betaine and 1,2-butanediol. The extraction yield and distribution coefficient values indicated the potential of NADES, prepared by friendly compounds of betaine and polyalcohols, as alternative green solvents in the solvent extraction process when separating free fatty acids from palm oil."

Indonesia is the largest palm oil producer in the world since overtaking Malaysia in 2008. The palm oil industry has a significant contribution to Indonesia's Gross Domestic Product. The 2019 Renewable Energy Directive II to the Delegated Act policy implemented by the European Union threatens the sustainability of the Indonesian palm oil industry with plans to stop using palm oil by 2030. To overcome this, Indonesia is trying to find new markets for palm oil by collaborating with various countries, one of which is the United Arab Emirates (“UAE”) as stated in IUAE-CEPA. This research analyzes the process of establishing the IUAE-CEPA as well as the potential for increasing Indonesian palm oil exports with the implementation of the IUAE-CEPA. This research is normative juridical research using a combination of doctrinal and non-doctrinal methods. In this research, it was found that the formation of IUAE-CEPA could support trade between Indonesia and the UAE and help Indonesia access new markets, not only the UAE, but also other Middle Eastern countries with the PEA as an entry point."

"The combination of baffled air flotation and a membrane system for the treatment of palm oil mill effluent (POME) was studied. The POME was obtained from a palm oil factory in PTPN I Tanjong Seumantoh, Aceh, Indonesia. Operation variables and conditions, such as the hydraulic retention time and air flow rates, were varied to find the optimum process. The air flotation process is able to reduce the concentration of suspended solids and fats/ oils contained in the wastewater, which increases the performance of the membrane by reducing clogging. The results showed that this method was promising for POME treatment. The optimum organic removal efficiency of the air flotation pretreatment was obtained at HRT = 5 days and at an air flow rate of 11 L/min. The effluent was subsequently passed through an anaerobic membrane system to achieve the highest removal efficiency treatment. The removal efficiency of chemical oxygen demand (COD), total suspended solids (TSS), turbidity, mixed liquor suspended solids (MLSS), mixed liquor volatile suspended solids (MLVSS), and fats/oils after passing through the membrane system were 97%, 93.9%, 99.8%, 94.5%, 96.2%, and 99.9%, respectively. The results also showed that the pH could be neutralized to 6.18, while a dissolved oxygen (DO) level of 1.60 mg/L could be achieved. A high quality of effluent was obtained, which met the standards for POME effluent."

Diplomasi ini bisa dilakukan oleh aktor non-negara, seperti Serikat Petani Kelapa Sawit (SPKS). Tujuan penelitian ini adalah untuk mengkaji upaya diplomasi yang dilakukan aktor SPKS dalam meningkatkan kesejahteraan petani sawit kecil dan menarik investasi untuk berbagai program peremajaan sawit. Metode yang digunakan adalah pendekatan kualitatif dengan metode studi kasus. Penelitian ini merupakan satu kasus implementasi diplomasi ekonomi oleh aktor non-negara. Penelitian ini juga menggunakan analisis induktif, yaitu berbagai data kecil dan khusus mengenai strategi lobi yang dilakukan SPKS melalui petisi online di change.org akan ditelaah dan diinterpretasikan, untuk kemudian ditarik gambaran yang lebih umum mengenai upaya diplomasi ekonomi oleh aktor non-negara. Sementara konsep yang digunakan adalah konsep petisi online. Hasilnya, petisi online yang dilakukan SPKS telah mampu menarik perhatian publik, namun masih perlu dukungan dari pemerintah. Simpulan penelitian ini adalah perlu ada sinergisitas antarkementerian di Indonesia dan pengusaha untuk mendukung petisi online yang dilakukan SPKS, seperti Kementerian Pertanian, Badan Pengelola Dana Perkebunan Kelapa Sawit (BPDPKS), Kementerian Perindustrian, Kementerian Keuangan, Bappenas, dan Badan Koordinasi Penanaman Modal (BKPM). Seluruh pihak tersebut berkolaborasi untuk meningkatkan kualitas sawit domestik, mengembangkan kompetensi, dan menyejahterakan petani sawit."

"The research aims to scale up a small-scale stirred batch reactor to a large-scale stirred batch reactor in order to degum crude palm oil for use as a raw material in biodiesel production. The scale-up is based on the similarity of fluid Reynolds numbers in the two differently sized reactors. To achieve this aim, computational fluid dynamic modeling and simulations of the two reactors were performed. A small-scale palm oil degumming process was carried out in a 250 cc autoclave reactor using a magnetic stirrer at 500 rpm. The simulation results of this small reactor yielded a fluid Reynolds number in the range of 5 to 3,482. The large-scale reactor proposed in this research is 1.25 m3 in volume and is equipped with two impellers: a pitched blade impeller and a Rushton turbine impeller. The pitched blade impeller is placed over the Rushton turbine impeller. They are rotated at 100 rpm. Under this setting and operation, the resulting fluid Reynolds number was in the range of 486 to 202,000. This result indicates that the large-scale reactor was able to reproduce the reaction performance obtained in the small-scale reactor."
