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%.

Advances in waste management offer huge possibilities for economic and social utilization of residues from coffee production such as the pulp and husk. Coffee pulp are obtained during coffee production around 20-45% of raw material either it processed wet or dry. In Gayo Highland areas, as a centre of Arabica production in Indonesia, coffee production known as semi-drying process where numbers of coffee residues arise up to 40% of total coffee berries. For local farmers pulp and husks often be decompose by burning, whether several alternatives have been attempted individually, either used as fertilizer, livestock feed and compost. However the applications above cover only small number of robust coffee residues. Therefore studies have been conducted to explore possibility to extract pectin from coffee pulp. Implementation of SWOT analysis and Risk Analysis by FMEA gain to enhance the information of strength, weakness, opportunity and threats of extraction pectin from coffee pulp/husks demonstrated that this attempt have higher possibility to be more efficient than others trial for both economically and ecologically. Furthermore, moisture contents, ash and crude fiber are examined from fresh pulp/husk which are stored in room temperatures for 16 days, 24 days and 30 days. The data demonstrated that length of storage up to 30 days has impact on increasing ash (up to 12.66% from 1.38%) and solid fiber contents (up to 28.24% from 2.70%) whilst moisture are decreased (down to 15.51% from 86.08%) which emphasizes that delaying production or prolonging the storage of coffee residues might not have any impact on product quality

Produk pangan berbasis emulsi seperti susu, mayonnaise, salad dressing dan margarin sangat diminati masyarakat. Emulsi biasanya distabilkan oleh surfaktan, protein dan polisakarida. Pati termasuk biopolimer polisakarida yang berperan penting sebagai penstabil, namun harus dimodifikasi terlebih dahulu untuk memperbaiki sifat fisiko-kimianya. Penelitian bertujuan untuk menguji peranan pati sukun termodifikasi OSA (Octenyl Succinic Anhydride) sebagai penstabil emulsi minyak dalam air (m/a) bersama-sama dengan lesitin sebagai surfaktan. Desain penelitian menggunakan Rancangan Acak Lengkap Faktorial dua faktor, yaitu penambahan pati sukun OSA (1% dan 2%) serta konsentrasi minyak (25% dan 40%) dengan tiga kali ulangan. Pati sukun terlebih dahulu dikarakterisasi dengan mengukur kadar air, abu, serat, protein, dan kadar lemak sebelum dan setelah modifikasi serta pengukuran derajat substitusi (DS). Adapun parameter kestabilan emulsi yang diuji meliputi pengukuran viskositas, penghitungan nilai creaming index (CI), dan emulsifying activity (EA) selama penyimpanan 10 hari. Analisa proksimat menunjukkan nilai yang tidak jauh berbeda antara pati sebelum dan sesudah modifikasi kecuali kadar protein yang menurun secara signifikan dari 5,25 % menjadi 3,50% setelah pati dimodifikasi. Nilai derajat substitusi pati sukun modifikasi adalah 0,0243. Hasil penelitian menunjukkan bahwa kedua perlakuan berpengaruh sangat nyata terhadap viskositas dan nilai CI, dimana peningkatan konsentrasi OSA dan minyak menurunkan nilai CI namun meningkatkan viskositas emulsi yang dihasilkan. Penyimpanan emulsi selama 10 hari menunjukkan bahwa peningkatan konsentrasi pati OSA dan minyak meningkatkan nilai EA yang membuktikan bahwa pemisahan emulsi dapat diminimalkan selama penyimpanan. Emulsi yang paling stabil (nilai EA 100%) diperoleh dari perlakuan terbaik yaitu konsentrasi 2% pati OSA dan 40% minyak.

Dataran Tinggi Gayo (DTG) merupakan produsen kopi Arabika terluas dan hasil panen terbesar di Indonesia. Kualitas biji dan citarasa kopi dipengaruhi oleh beberapa faktor, salah satunya adalah kondisi kematangan buah. Campuran buah merah, hijau dan rusak sering ditemukan di lapangan yang mempengaruhi mutu kopi. Penelitian bertujuan untuk mengetahui kualitas buah dan menghitung korelasinya dengan kualitas kopi beras dan seduhannya. Penelitian dilaksanakan di Kabupaten Aceh Tengah, bulan April-Juni 2021. Penelitian dilakukan melalui wawancara kepada petani dan pengepul, serta mengamati kualitas buah merah, mutu fisik dan mutu seduhan (SCAA) kopi yang ditanam pada tiga ketinggian tempat yang berbeda (E1 = 1000-1200 mdpl, E2 = 1201-1400 mdpl dan E3 = 1401-1600 mdpl), berdasarkan Rancangan Acak Kelompok (RAK) nonfaktorial. Hasil penelitian menunjukkan bahwa ketinggian tempat tumbuh berpengaruh terhadap kualitas buah yang dipanen. Semakin tinggi tempat tumbuh maka semakin baik kualitas kopi, yang ditandai dengan menurunnya persentase buah rusak, yaitu 31,48%, 18,75%, dan 10,83% pada ketinggian E1, E2, dan E3. Ketinggian tempat juga berpengaruh terhadap kualitas kopi beras, yaitu cenderung mempunyai ukuran yang lebih besar dan nilai cacat lebih rendah. Hasil cupping test menunjukkan kualitas kopi termasuk specialty dengan skor rata-rata 82,67 + 0,98. Kopi dari lokasi yang lebih tinggi mempunyai skor atribut fragrance, flavor, dan acidity yang lebih tinggi. Analisis korelasi menunjukkan adanya korelasi positif kuat antara persentase buah kopi rusak dengan nilai defect kopi beras, korelasi positif moderat antara persentase buah mengapung dengan nilai defect kopi beras dan korelasi positif lemah antara persentase buah hijau dengan skor total cup test.

Kopi umumnya dikonsumsi dalam bentuk seduhan, dimana biji kopi merupakan bahan baku utamanya. Pada pengolahan pembuatan kopi, bagian yang tidak diolah kembali atau yang biasa dijadikan limbah adalah daging kopi (pulp). Pulp kopi sejauh ini baru dimanfaatkan untuk pembuatan pupuk dan pakan ternak. Salah satu produk yang dapat dibuat dari limbah pulp kopi yaitu minuman sari buah. Pembuatan minuman sari buah pulp kopi juga dapat ditambahkan dengan campuran buah lainnya untuk menambah citarasa dari minuman sari buah tersebut. Penambahan gula 20-10% biasanya dilakukan agar menghasilkan minuman sari buah dengan rasa yang lebih manis. Penelitian ini dilakukan untuk mengetahui pengaruh dari penambahan terong belanda dan gula terhadap mutu sensori, kandungan antioksidan dan total fenol yang terdapat di minuman sari pulp kopi. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan pola faktorial yang terdiri atas 2 (dua) faktor. Faktor I adalah rasio pulp kopi dan terong belanda (B) 3 taraf yaitu B1 = 100:0 (pulp kopi : terong belanda), B2 = 90:10, dan B3 = 80:20 dan Faktor II adalah konsentrasi gula (G) 3 taraf yaitu G1 = 20% (dari volume minuman sari pulp kopi) , G2 = 15% dan G3 = 10%. Setiap perlakuan diulang sebanyak 3 kali sehingga didapatkan 27 satuan percobaan. Hasil penelitian menunjukkan bahwa Perbandingan Bahan Baku (B) berengaruh sangat nyata (P≥0,01) terhadap warna minuman sari pulp kopi dan Konsentrasi Gula (G) berpengaruh sangat nyata (P≥0,01) terhadap rasa dan aroma minuman sari pulp kopi. Sedangkan interaksi antara Perbandingan Bahan Baku (B) dan Konsentrasi Gula (G) berpengaruh sangat nyata (P≥0,01) terhadap aktivitas antioksidan, pH dan total padatan terlarut minuman sari pulp kopi.

Sie reuboh is a traditional cuisine from Aceh Besar district which use red meat, tallow, vinegar and some blended spices. Normally, Acehnese cooks this cuisine in with traditional clay pot. As cooking utensil, clay pot is vulnerable to breakage and has slow heat propagation compared to stainless steel pot which has long usage and good heat conductor. The use of packaging such as nylon plastic and aluminum foil in storage is also expected to affect the quality of sie reuboh. This study aims to find out sensory profile of produced sie reuboh by using ten attributes (colour/brightness, aroma (sour, spicy, meaty), flavor (hot spicy, sour, salty, umami) and texture (tenderness, chewiness). Sie reuboh was cooked in two types of cooking ware (earth clay pot and stainless steel pot) and then store in nylon and aluminum foil packaging for 7 days. The obtained data is statistical analyzed with ANOVA and DMRT. The results showed that attribute sour aroma, hot spicy flavor, umami and tenderness of sie reuboh cooked with stainless steel has higher notes, whereas other attributes showed no significant effect. Type of packaging also showed no significant effect for these ten attributes except sour aroma. As conclusion, it can be stated that stainless steel provides sie reuboh with better sensory properties compare to clay pot.
