Chicken intestine is a part of internal organs, which are rich in protein and protease enzymes. The protease enzyme could self-degrade (autolytic degradation process) proteins in the chicken intestine at an appropriate pH and incubation time. This process produces a shorter chain polypeptide having a higher solubility protein called protein hydrolysates. Protein hydrolysates have shown a good impact in foods and health applications. In this study, the autolytic degradation of chicken intestine was carried out to obtain protein hydrolysates. The effect of pH and incubation time on the dissolved nitrogen (%N) and protein content ([protein]) in hydrolysate from the autolytic degradation of chicken intestine explained in this paper. The incubation pH used in this study was 2.5, 3.5, 5.5., and 6.3 while the the incubation time was 0, 6, 12, and 18 h. Chicken intestine was incubated for 18 h at several different pHs, and the % N and protein content were determined by using Formol titration and Bradford methods, respectively, within 6 h intervals. It was obtained the % N and [protein] content increase at pH 2.5 and 3.5 during 18 h of incubation time and they were decreased at a higher pH. The optimum % N and [protein] content were 5.98±0.51 % and 25.3±0.04 mg mL-1, respectively, obtained at pH of 2.5 during 18 h incubation time.

Ketergantungan masyarakat terhadap penggunaan pupuk kimia menyebabkan turunnya produktivitas tanah. Guna mengurangi kerusakan lingkungan diperlukan penyeimbangan penggunaan pupuk kimia dengan pupuk organik. Bahan yang berpotensi untuk digunakan dalam pembuatan pupuk organik adalah limbah pertanian, salah satunya pemanfaatan limbah kulit buah kakao. Kulit buah kakao memiliki kandungan hara berupa C-organik yang tinggi yakni sekitar 26,61%. Dalam pembuatannya diperlukan teknologi tepat guna dan dukungan dari masyarakat untuk menjamin produksi yang berkelanjutan. Kegiatan ini bertujuan untuk mengembangkan teknologi tepat guna dalam produksi pupuk organik cair sehingga dapat dimanfaatkan masyarakat untuk meningkatkan efektivitas produksi baik secara kualitas maupun kuantitas. Kegiatan pengabdian dikemas dalam bentuk sosialisasi untuk memberdayakan kader PKK di Desa Banjar Sengon, Kecamatan Patrang, Kabupaten Jember terkait proses pengolahan limbah kulit buah kakao menjadi pupuk organik cair. Produksi POC dari limbah kulit buah kakao diharapkan mampu meminimalisir jumlah limbah kulit buah kakao dan menjadi langkah sederhana dalam upaya mewujudkan pertanian berkelanjutan dengan mengurangi ketergantungan terhadap pupuk kimia serta membuka peluang baru dalam sektor ekonomi lokal.Kegiatan workshop sangat menjadi parameter, dimana 90% dari kegiatan yang dilakukan membuat warga menjadi lebih paham dan andal dalam mengolah limbah kulit kakao menjadi pupuk organik cair. Warga juga aktif bertanya dan memberikan ide-ide penggunaan alat tersebut untuk limbah sejenis sehingga penggunaan TTG dapat maksimal.

Shrimp waste containing chitin 15-20%. Chitin can be isolated enzymatically by using proteaseenzymes derived from the waste itself. Waste of shrimp marinated in 1M H2SO4 for 10 days at pH1-2 and do control the pH and concentration of N-total every 24 hours. So that, this process canreduce the use of chemicals and environmental pollution. Enzymatic chitin obtained ash content1.789% and 5.322% of N-total. Results of IR showed characteristic functional groups of chitin areOH 3390.5 cm-1, NH (secondary amide) 3348.71 cm-1, C = O 1648.20 cm-1, C-N at 1313.96 cm-1,C-O 1115, 28 cm-1. Chitin is dissolved in 8% NaOH / Urea 4% for 36 hours (-20oC). Hydrogelsmade with a ratio (1: 6); (1: 8); (1:16); (1:24) w / w. The results showed the increasing amount ofacrylamide monomer, the greater the value% graft and absorption of water. Enzymatic chitinhydrogel showed the maximum value % graft is 2492.073%; and water absorption 1.794 g / g. IRhydrogel results indicate primary amide N-H stretching of acrylamide at 3349.77 and 3202.88 cm-1, C = O 1662.03 cm-1Keywords: hydrogel, chitin, acrylamide, graft copolymerization

Onoceranoide type of triterpene was isolated from leaf of langsep (Lansium domesticum Corr.) Isolation is conducted by vacuum and flash column chromatography technics with Silika Gel 60 F, Silika Gel 60 (70-230 mesh), and Sephadex LH-20 powder as stationery phase and mixture of dichloromethane, methanol, ethyl acetate as mobile phase. The structure was identified by Infrared and NMR spectroscopy. It has moderate insecticidal activity to Spodoptera littura larvae with LC50 13,6 ppm.

Limbah udang banyak mengandung protein, mineral dan kitin sehingga dapat dijadikan sebagai sumber kitin. Kitin pada limbah udang dapat diisolasi secara kimiawi dan enzimatis. Isolasi secara kimiawi memberikan dampak yang kurang baik terhadap lingkungan karena penggunaan bahan-bahan kimia untuk mengisolasi kitin tersebut akan menghasilkan limbah yang dapat mencemari lingkungan. Oleh karena itu isolasi kitin dilakukan secara enzimatis autolisis untuk mengurangi penggunaan bahan kimia dengan menggunakan enzim protease yang terdapat dalam limbah udang itu sendiri dengan cara di-blender dan diinkubasi selama 10 hari pada pH 2 menggunakan asam fosfat. Kitin hasil isolasi mengandung kadar N 6,6 % pada hari terakhir inkubasi. Kitin yang diperoleh diturunkan menjadi kitin maleat dengan memanaskan kitin dan anhidrida maleat pada fase padat pada suhu 120o C dalam waktu 3,5 jam. Modifikasi kitin menjadi kitin maleat digunakan untuk meningkatkan sifat hidrofilistas kitin. Karakterisasi FTIR dari kitin yang dimodifikasi dengan anhidrida maleat menunjukkan terbentuknya gugus fungsi baru yaitu ikatan ester yang ditunjukkan oleh vibrasi dari –C=O ester pada bilangan gelombang 1712 cm-1. Uji peningkatan hidrofilisitas dilakukan melaui uji daya serap air untuk mengetahui kemampuan kitin maleat dalam menyerap air. Kitin mempunyai daya serap air 0,97g/g sedangkan kitin maleat yaitu 2,78g/g. Gugus karboksilat (-COOH) yang terikat pada kitin maleat yang menyebabkan meningkatnya kemampuan daya serap air kitin maleat karena adanya gugus karboksilat (-COOH) yang bersifat hidrofilik.

Shrimp is an Indonesian’s export commodity with high economic value increasing every year. Usually, shrimps are exported in the form of frozen shrimp without shells, heads, tails, and entrails. It resulted in the accumulation of shrimp waste leading to the increasing environmental pollution. Shrimp waste contains high contents of chitin which can be processed to a chitosan owing several benefits. The purpose of this study is to determine the optimum condition of the synthesis of chitosan from chitin isolated by the autolysis method. The deproteination was carried out by soaking the shrimp waste in an acidic solution (pH 2 – 3) for 10 d. The demineralization process was done by reacting the deproteinated solids in a hydrochloric acid solution at pH 0 – 1 for 24 h. Parameters varied in this study time (1 – 3 h), chitin to NaOH ratio (1:10 – 1:30 (w/v)), and temperature (60 – 120℃). The higher all parameters used, the higher the obtained degree of deacetylation (DD) which is in the range of 18.35±1.13 to 48.6±0.51%. On the other hand, the obtained yield decreased from 50.66±1.98% to 47.78±0.81%. The optimum condition was obtained at a synthesis temperature of 120℃, chitin to NaOH ratio of 1:20 g/mL, and time of 3 h producing chitosan with DD of 54.25 ± 2.27%, and yield of 47.7 ± 0.65%. Chitosan synthesized using optimum conditions produced a relatively homogeneous thin film. Polyaniline was then introduced to the film to obtain a smart film prototype. This smart film was able to detect the pH changes proven by the change in its color. The smart film also could be potentially used as a “smart pack” for detecting product decay which releases ammonia gas.
