Generally there are two coffee varietes cultivated in Indonesia, known as Arabica and Robusta coffee. Arabica distinctively known for its distinctive quality but limited quantity compared to robusta which is commonly use for commercial coffee production due to its robust productivity. Nowadays, global market demand encourages a huge variety of coffee product, based on coffee such as espresso. The quality of espresso is influence by many factors such as roasting technique and ratio blending of coffee ground. This study aims to determine the influence of blending ratio and roasting techniqus to the chemical compounds of coffee ground and its espresso brewed. This research used Factorial Random Design, consists of 2 factors. First factor is ratio of blending Arabica and Robusta with three levels ratio; B1=70:30; B2=80:20; and B3=90:10). The second factor is roasting technique, consisting of 2 levels of conventional roasting(P1) and torrefacto (P2). Each treatment was repeated 3 replications to obtain 18 units of experiment. Measured parameters are pH of brewed espresso and moisture (%), ash (%), protein (%), lipid (%) and caffeine (%) contents of coffee ground. The results showed that the blending ratio was highly significant (P≤0,01) to the moisture and protein contents of coffee grounds and pH of resulted espresso. The best treatment was obtained from combination of B1P1 treatment (combination blending ratio (70%:30%) and conventional roasting) with 2.00% moisture content, 4.83% ash, 13.04% protein, 10.41% fat, 81.17% carbohydrate and caffeine 1.49%.

ABSTRACTIndonesia is the world's largest producer of crude palm oil (CPO). Even so, the trend of international trade in Indonesian CPO products has decreased in the last 10 years with a value of -10.19%. The decline in world demand for CPO can be dealt with by utilizing CPO as a biofuel for domestic use, like biodiesel. The purpose of this study is to determine the competitiveness of Indonesian CPO in global trade and determine the parameters of the quality requirements of CPO and biodiesel. The competitiveness analysis method uses the Revealed Comparative Advantage (RCA) method, while the analysis of the potential quality of CPO as a biofuel is carried out by analyzing the Indonesian National Standard (SNI). CPO trade in the global market is controlled by Indonesia with a market share of 50% and Malaysia 25.6%, with the declining trade trend in the last 10 years relatively (2010-2019) of -6.91%. The level of competitiveness of Indonesian CPO products in 2019 is very strong, but on average in the last 10 years, the level of competitiveness of Indonesian CPO is no better than that of Malaysia. Indonesia has SNI 01-2901-2006 and SNI 7182: 2015 as a determinant of the quality of CPO and biodiesel products developed in Indonesia so that the CPO and biodiesel produced fullfil sacurity and safety aspects when used by consumers.Keywords: crude palm oil (CPO), competitivenessv, quality, Indonesian National Standard (SNI) ABSTRAKIndonesia merupakan negara produsen minyak kelapa sawit mentah/ Crude Palm Oil (CPO) terbesar di dunia.

Agricultural by-products have several disadvantages as fuel, such as low calorific values and high ash contents. To address these disadvantages, this study examined the mixing of agricultural by-products and spent coffee grounds, for use as a solid fuel, and the improvement of fuel characteristics through torrefaction. Pepper stems and spent coffee grounds were first dried to moisture contents of <15% and then combined, with mixing ratios varying from 9:1 to 6:4. Fuel pellets were produced from these mixtures using a commercial pelletiser, evaluated against various standards, and classified as grade A, B, or Bio-SRF. The optimal ratio of pepper stems to spent coffee grounds was determined to be 8:2. The pellets were torrefied to improve their fuel characteristics. Different torrefaction temperatures improved the mass yields of the pellets to between 50.87% and 88.27%. The calorific value increased from 19.9% to 26.8% at 290 °C. The optimal torrefaction temperature for coffee ground pellets was 230 °C, while for other pellets, it was 250 °C. This study provides basic information on the potential enhancement of agricultural by-products for fuel applications.

Semi-crystalline carbon biochar is derived from spent coffee grounds (SCG) by a controlled pyrolysis process at high temperature/pressure conditions. Obtained biochar is characterized using XRD, SEM, and TEM techniques. Biochar particles are in the micrometer range with nanostructured morphologies. The SCG biochar thus produced is used as reinforcement in epoxy resin to 3 D print samples using the direct-write (DW) method with 1 and 3 wt. % loadings. Rheology results show that the addition of biochar makes resin viscous, enabling it to be stable soon after print; however, it could also lead to clogging of resin in printer head. The printed samples are characterized for chemical, thermal and mechanical properties using FTIR, TGA, DMA and flexure tests. Storage modulus improved with 1 wt. % biochar addition up to 27.5% and flexural modulus and strength increased up to 55.55% and 43.30% respectively. However, with higher loading of 3 wt. % both viscoelastic and flexural properties of 3D printed samples drastically reduced thus undermining the feasibility of 3D printing biochar reinforced epoxies at higher loadings.

Inflammatory bowel diseases (IBD) are a group of chronic, incurable diseases of the digestive tract, the etiology of which remains unclear to this day. IBD result in significant repercussions on the quality of patients’ life. There is a continuous increase in the incidence and prevalence of IBD worldwide, and it is becoming a significant public health burden. Pharmaceuticals commonly used in IBD management, for example, mesalamine, sulfasalazine, corticosteroids, and others, expose patients to diverse, potentially detrimental side effects and frequently do not provide sufficient disease control. The chronic inflammation underlies the etiology of IBD and closely associates with oxidative/nitrosative stress and a vast generation of reactive oxygen/nitrogen species. Relative to this, several substances with antioxidant and anti-inflammatory properties are now intensively researched as possible adjunctive or independent treatment options in IBD. Representatives of several different groups, including natural and chemical compounds will be characterized in this dissertation.

Analysis of the main trends in the development of the market for higher education services, affecting the transformation of university financing models, shows that improving the quality of educational services in Russian universities directly depends on an increase in the share of revenues received from research and development, as well as the ability of universities to present the results of their research and development in the form of a complete product from a marketing point of view and build a competent strategy for promoting innovations in the market. In the context of creating a long-term strategy for increasing the competitive advantages of leading universities, the author pays special attention to Project 5–100 of the Ministry of Education and Science of the Russian Federation, the purpose of which is to maximize the competitive position of a group of leading Russian universities in the global market of educational services and research programs. It is noted that university funding comes from various sources, while budgetary revenues dominate the structure of income, and the reduction in budgetary provision significantly affects the financial condition of Russian universities. The author comes to the conclusion that the forms and mechanisms of financial management of universities and research organizations are not strictly regulated, they independently choose the sources of funding.
