Abstract

Natural dyes are substances obtained from animals or plants through extraction. The application of synthetic dyes can affect to environmental problems, therefore replace it with natural dyes is become an alternative. Cocoa pod husk still considered as a waste, whereas it is one of source for natural dyes. Cacao pod husk contains flavonoids, tannins, and β-carotene compounds which is generate colour. Natural dye is extracted from the husk of the cocoa pod and applied to cotton cloth. Extraction of cocoa husk dyes was carried out with distilled water at 60˚C with variations of 1, 2, and 3 hours. The resulting extract contains positive tannins but negative β-carotene. Variations in the extraction time of natural dyes affect the tannin content extracted. The tannin content extracted with variations of 1, 2, and 3 hours was 18.32; 18.67; and 17.93 ppm. Respectively chitosan-based mordant has a significant effect on the color yield of the fabric. Fabrics with mordant have a darker color than fabrics that are not applied with mordant process. The use of nanochitosan and citric acid crosslinkers can maintain the aging color of the fabric. The FTIR results on the fabric showed that color aging occurred due to the presence of ester groups formed between chitosan and dyes. Chitosan-based mordant coating provides better color than without mordant coating. Fabrics coated with chitosan had the best fastness value of 4 (Good).

Abstract

Komoditas kopi merupakan komoditas yang banyak digemari dengan Coffea arabica dan Coffea canephora sebagai kopi yang sering kali dibudidayakan di Indonesia. Kopi harus memenuhi kualitas Standar Nasional Indonesia, karenanya pada penelitian ini ditempuh metode identifikasi mutu kopi mengacu pada (SNI) 2907-2008. Sampel dalam penelitian ini yaitu kopi arabika (Coffea arabica) varietas Andungsari 2K (AS 2K), Komasti (Komposit Andungsari), serta kopi robusta (Coffea canephora) asal KP Kaliwining dan KP Sumberasin (SA). Hasil data penelitian menunjukkan bahwa kopi arabika hasil panen 2021 sesuai dengan uji mutu fisik SNI 01-02907-2008, varietas Andungsari 2K masuk dalam kategori mutu 2, dan Komasti masuk dalam kategori mutu 2. Kopi robusta hasil panen 2021 berdasarkan uji fsik sesuai dengan SNI 01-02907-2008, BP 308 masuk dalam kategori mutu 3, dan SA 237 masuk dalam kategori mutu 6.   Kata kunci: Coffea arabica, Coffea canephora, karakteristik fisik, kualitas biji Coffee is a very popular commodity, with Coffea arabica and Coffea canephora being the most commonly cultivated coffees in Indonesia. Coffee must meet the quality requirements of the Indonesian National Standard, so the method of determining coffee quality used in this study is (SNI) 2907-2008. The arabica coffee (Coffea arabica) Andungsari 2K varieties (AS 2K), Komasti (Andungsari Composites), and robusta coffee (Coffea canephora) clones of KP Kaliwining and KP Sumberasin were used in this study (SA). According to the findings of the research, arabica coffee harvested in 2021 meets the physical quality test of SNI 01-02907-2008, the Andungsari 2K variety is in quality category 2, and Komasti is in quality category 2.   Keywords: Bean quality, Coffea arabica, Coffea canephora, physical characteristics

Abstract

Cocoa bean shell is a by-product of processing chocolate products that can be used as a tea infusion because it contains bioactive compounds such as polyphenols which act as antioxidants. Roasting plays a very important role in the development of aromas and flavors. The temperature commonly used in roasting is about 100 – 150 ºC. Phenolic content plays a role in the formation of sensory properties of the product due to the presence of interaction with proteins through the Maillard reaction that occurs in the roasting process. This study aims to determine the effect of roasting temperature on the antioxidant activity of tea infusions from cocoa bean shells. The methods used in this study are the folin-ciocalteu method and the DPPH method. Cocoa bean shell tea with a roasting temperature of 100ºC, 20 minutes has the highest total phenols, antioxidant levels, and radical scavenging activity of 21.54 ± 0.37 mg GAE/g; 12.80 ± 0.17 mg AA/g; and 85.18 ± 1.28%. The total amount of phenols has a very strong correlation to antioxidant levels, radical scavenging, the color value of the brew L*, b*, and is inversely proportional to the color value of a*. Cocoa bean shell tea roasting temperature of 140ºC, 18 minutes has the highest IC50 value of 22.76 mg /ml. In addition, the roasting temperature can affect the sensory attribute character of cocoa bean shell tea.

Abstract

The manual cracking and separation of cocoa beans' husk result in low working productivity, a high percentage of broken beans, and the difficulty of separating cocoa nibs from the husk. This poses a challenge for both farmers and industrial players in cocoa bean management, leading to the development of a cocoa bean dehusking machine (desheller). This study was conducted to analyze the performance of the cocoa bean dehusking machine. The research involved motor speeds of 500, 700, and 900 rpm, combined with roasted cocoa bean grades AA, A, and B. The observed parameters included working capacity, yield, nib percentage, percentage of husk adhering to nibs, power transmission efficiency, and power requirements. The working capacity of the cocoa bean deshelling machine ranged from 17,413 to 41,481 kg/h, with yields between 73.83% and 80.83%. The nib percentage varied from 92.13% to 98.61%, while the percentage of husk adhering to nibs ranged from 1.08% to 6.92%. Power transmission efficiency was between 92.24% and 94.14%, and power requirements ranged from 601.33 to 645.33 watts. The best treatment in this study was found at a motor speed of 900 rpm with cocoa bean grade of AA.  Keywords:  Desheller,  Nibs,  Roasted cocoa beans, Shell,  Yield
