“…Gugus fungsi yang terkonfirmasi dengan serapan FTIR menunjukkan bahwa kitosan berhasil disintesis dari proses deproteinasi, demineralisasi baik dengan perbandingan (kitosan dan HCl) a(1:10) maupun b(1:15), serta deasetilasi. Wulandari et al (2020) menyatakan bahwa ciri khas karakteristik kitosan adalah pada gugus amida dan gugus hidroksil. Letak serapan khas gugus gugus amida pada bilangan gelombang 1655-1310cm -1 sedangkan gugus hidroksil terletak pada bilangan gelombang 3350-3300 cm -1 .…”

Limbah cangkang kepiting bakau yang dihasilkan dari industri pengolahan kepiting bakau di Kota Tarakan menjadi salah satu penyebab masalah pencemaran lingkungan. Salah satu cara untuk dapat mengurangi risiko pencemaran yaitu dengan mengolah limbah cangkang kepiting bakau menjadi kitosan. Penelitian terkait modifikasi pada tahap demineralisasi dilakukan karena kepiting bakau mengandung mineral yang tinggi sehingga akan mengurangi kualitas kitosan yang dihasilkan. Tujuan penelitian ini adalah mendapatkan optimasi tahapan demineralisasi pada ekstraksi kitosan dari cangkang kepiting bakau (Scylla sp.) melalui analisis rendemen, kadar air, abu, nitrogen total, FTIR, derajat deasetilasi, dan SEM-EDX. Perlakuan pada penelitian ini yaitu pada tahapan demineralisasi dilakukan perlakuan perbandingan berbeda antara serbuk cangkang kepiting bakau dan HCl 1N yaitu a (1:10) dan b (1:15). Hasil penelitian ini diketahui mutu kitosan cangkang kepiting bakau memiliki nilai rendemen, kadar air, kadar abu, dan nitrogen total sebesar (15,08±0,04%, 1,65±0,00%, 2,87±0,07%, 1,35±0,00%) pada perbandingan 1:10 dan (6,37±0,04%, 1,66±0,01%, 1,75±0,00%, 1,29±0,004%) pada perbandingan 1:15. Derajat deasetilasi pada kitosan a (47%) tidak sesuai dengan ketiga standar karena dibawah (≥70%), sedangkan kitosan b (76%) sesuai dengan standar Protan Laboratory dan SNI (≥70%). Unsur-unsur kitosan cangkang kepiting bakau yang terdeteksi dari analisis SEM EDX terdiri dari C, O, Ca, Mg, Al. Unsur C dan O yang terdeteksi adalah komponen pembentuk kitosan. Karakteristik mutu kitosan terbaik dihasilkan pada tahap deminerarisasi dengan perlakuan perbandingan sampel dan HCl 1N b(1:15) karena terbukti sesuai dengan standar mutu kitosan.

“…According to Wulandari et al (2020) the optimum condition of the degree of deacetylation of chitosan using 60% NaOH. The higher the concentration of NaOH, the greater the value of the degree of deacetylation, so 60% of the NaOH concentration is used.…”

Chicken meat is a nutritious food that can increase immunity but has perishable food properties that are easily damaged so it is necessary to add preservatives, namely chitosan as an edible coating to protect the meat from microbial contamination. Gourami (Osphronemus goramy) scales have the potential to be processed as chitosan. Through 3 stages, namely deproteination, demineralization, and deacetylation. The purpose of this study was to determine the effect of adding chitosan with gourami fish scales and cloves as an edible coating on the quality of raw chicken meat at room temperature for 9 h. This study used a factorial completely randomized design (3×3), with factor A: concentration of chitosan solution (0%, 1%, and 2%) and factor B: concentration of clove solution (0%, 1%, and 2%) and repeated 3 times. The results showed that the control treatment without clove and chitosan after 9 h of storage at room temperature had a significant difference in effect on the treated samples. The best treatment was found in the interaction of 2% chitosan (K2) and 2% cloves (C2) with microbial contamination of 2×10 5 CFU/g so that it still meets the standards of the National Standardization Agency (BSN) namely, chicken meat has a maximum requirement of 1×106 CFU/g, which can maintain the quality of meat, both in terms of pH, water content, and acceptability of organoleptic values which are still favored by panelists.

Jernang is used an ingredient in making medicines, efficacious gum can stop bleeding (static blood dispel, reduce pain (relieve pain), injury trauma due to fractures (traumatic injuries causing fracture) bruising medication, sprains stop bleeding due to bruising and stop bleeding protects the festering wounds surface to rot, growing the flesh tissue, and relieving the pain in chronic wounds (chronic non-healing sores) [16,18]. According to phytochemical test, jernang contained a group of metabolic compounds secondary to flavonoids, terpenoids, and antibacterial activity tests giving clear zones (+) to E. coli, Salmonella and S.

The development of chitosan nanoparticles and jernang (Daemonorops draco) as wound medicine materials have received a lot of attention from researchers. In this research the two materials will be combined. The antifungal of the materials determined based on inhibition test of Candida albicans and Malassezia furfur. The wound healing activities determined based on the in vivo wound healing test on Wistar rat (Rattus novergicus). The materials applicated on wound dressing patch. Chitosan was sinthesized from green mussels shell waste (Perna viridis L). The result showed that the yield of chitosan was 64.67% and degree of deacetylation (DD) was 69.53%. Meanwhile, chitosan nanoparticles can be prepared based on ball mill process. The result showed that average of the particles size was 437.6 nm (nanoparticles size is 1-1000 nm). Jernang was obtained by maseration process using ethanol organic solvents technical. The yield was 22.41% and showed positively of alkaloid, saponin, flavonoid and triterpenoid test. F3 has highest activies on antifungal and wound healing test results.
