Abstract

Roasting is the process of forming flavor to coffee beans which is carried out using high temperatures. Currently, there is still little data on how the proper roasting.  This research was conducted to determine the effect of roasting time on changes in the physico-chemical properties of Arabica coffee. The research design used was a completely randomized design (RAL) non factorial with roasting time treatment consisting of 10 minutes, 12 minutes, 14 minutes, 16 minutes, and 18 minutes. The results showed that the roasting time had an effect on moisture content, ash content, degree of acidity, caffeine content, hedonic aroma, and arabica coffee color. Roasting temperature of 220°C with roasting time of 10 minutes was the best treatment to produce the best physical characteristics and quality of arabica coffee, namely with a water content of 2.41%, 4.09% ash content, 4.87 degree of acidity, 2.54% caffeine content, aroma scoring 3.80, color L 25,97.Keywords: Arabica coffee, roasting, roasting duration

Abstract

The roasting is the process of forming the color and aroma of green coffee beans. The coffee roasting process not only changes the physical appearance of the coffee beans but also rearranges the chemical makeup. This study aims to obtain the best roasting time on the physicochemical properties of Robusta Solok Radjo coffee beans based on SNI 01-3542-2004. The research design used was a completely randomized design (RAL) non factorial with roasting time treatment consisting of roasting time consisting of 8 minutes, 10 minutes, 12 minutes, 14 minutes, and 16 minutes. The results showed that the duration of roasting had a significant effect on moisture content, ash content, degree of acidity, and caffeine content in roasted coffee beans. The best treatment in this study was L1 treatment with a roasting time of 8 minutes. The L1 treatment of roasted coffee beans in this study had an average value of water content of 2.22%, ash content of 3.09%, degree of acidity 5.06, caffeine content 1.56%, color index 27.65%.

Abstract

Mayonnaise is an oil in water (O/W) emulsion despite containing 70–80% fat and egg yolk.  The addition of extract ginger var. Rubrum serves as an ingredient that is able to cover the characteristic of mayonnaise of red palm oil taste and aroma and also contains high antioxidants.  The aim was to find the best mayonnaise of red palm oil with extract ginger var. Rubrum addition according to the SNI.  The experimental was arranged in a completely randomized design (CRD) with 3 treatments and replicated 3 times then continued tested using DNMRT at a 5% level.  The treatment was five-level extract ginger var. Rubrum addition: 0.5%, 1%, 1.5%, 2%, and 2.5%.  Parameters observed were moisture content, antioxidant activity, color with a colorimeter, and sensory evaluation on mayonnaise.  The result showed that the addition of extract ginger var. Rubrum significantly affected color, descriptive sensory assessments such as aroma, taste, and viscosity, hedonic assessments such as aroma and taste.  Whereas moisture content, color sensory assessment and hedonic viscosity were not significantly affected.  The best treatment was 2.5% addition of extract ginger var. Rubrum with a value of 25.83% moisture content, 87.45 ppm (strong) antioxidant activity, color with colorimeter L*: 55.27; a*: 11.36; and b*: 48.86 and preferred overall acceptance.

Abstract

This study aims to determine the status of palm sugar supply chain in Rambah Tengah Barat Village, Rambah District, Rokan Hulu Province through an approach Food Supply Chain Network. The focus of the study was palm sugar production in Rambah Tengah Barat Village, Rambah District, Rokan Hulu Province. The research method is carried out in a purposive sampling,The data types used are primary data and secondary data. The study phase analyzed the palm sugar supply chain in Rambah Tengah Barat Village, Rambah District, Rokan Hulu Province through an approach Food Supply Chain Network starting from looking at supply chain objectives, existing supply chain structure, business processes down to resources in the brown sugar supply chain. The results show that the distribution model of the supply chain starts from farmers, collectors, retailers, stores and end consumers. Institutional strengthening among farmers is needed by forming groups of asphalt farmers to produce jaggery that can satisfy consumer demand. Production capacity is very limited and the use of technology is simple.

Abstract

AbstractPlastic is a packaging material used as a container to protect and store food as well as non-food products essential for the community, specifically in Indonesia. This study aims to examine the effect of glycerol addition as a plasticizer on the physical characteristics of biodegradable plastic made from oil palm empty fruit bunches (OPEFBs). It was conducted through an experiment using a completely randomized design (CRD) consisting of 5 treatments and 3 replications. The treatments include P1, P2, P3, P4, and P5 with 1%, 1.5%, 2%, 2.5%, and 3% glycerol, respectively, in the formulation of biodegradable plastic. The results showed that the addition of glycerol had significant effects on water resistance, vapor transmission rate, tensile strength, and elongation, but had no significant effect on the biodegradability of plastic. Furthermore, the addition of glycerol as a plasticizer improved the elongation of biodegradable plastic made from OPEFB, but did not improve the characteristics of water resistance, vapor transmission rate, and tensile strength. The P1 treatment produced the best result as it generated a water resistance of 2.226%, vapor transmission rate of 16.306 g/m2/hour, tensile strength of 2.430 MPa, and elongation of 18.950%. In addition, the biodegradable plastic was able to decompose in two weeks.Keywords: biodegradable plastic, glycerol, oil palm empty fruit bunch AbstrakPlastik merupakan bahan kemasan yang digunakan sebagai wadah untuk melindungi dan menyimpan produk pangan dan non-pangan yang penting bagi masyarakat, khususnya di Indonesia. Tujuan penelitian ini adalah untuk menguji pengaruh penambahan gliserol sebagai plasticizer terhadap karakteristik fisik plastik biodegradable berbahan tandan kosong kelapa sawit. Penelitian ini dilakukan melalui eksperimen dengan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dan 3 ulangan. Perlakuan dalam penelitian ini adalah P1, P2, P3, dan P4 dengan penambahan gliserol berturut-turut sebanyak 1%, 1,5%, 2%, 2,5%, dan 3% dalam formulasi plastik biodegradable. Hasil penelitian ini menunjukkan bahwa penambahan gliserol berpengaruh nyata terhadap ketahanan air, laju transmisi uap air, kekuatan tarik, dan perpanjangan, namun tidak berpengaruh nyata terhadap uji biodegradabilitas plastik biodegradable. Penambahan gliserol sebagai plasticizer meningkatkan elongasi plastik biodegradable dari tandan kosong kelapa sawit, namun tidak dapat meningkatkan karakteristik ketahanan air, laju transmisi uap air, dan kekuatan tarik. Perlakuan P1 adalah yang terbaik karena menghasilkan daya tahan air sebesar 2,226%, laju transmisi uap air sebesar 16,306 g/m2/jam, kuat tarik sebesar 2,430 MPa, dan elongasi sebesar 18,95%. Plastik biodegradable juga mampu terurai dalam waktu dua minggu.Kata kunci: gliserol, plastik biodegradable, tandan kosong kelapa sawit
