Proteases have been widely used in cancer treatment, wounds healing, overcoming digestion disorder and other modern pharmaceutical applications. Proteases may be present in fruits and leaves of noni (Morinda citrifolia L.) since the plant has been used traditionally in wound healing. This research aimed to purify proteases from noni’s fruits and leaves at two maturity stages, i.e. fruits with green-yellow (TK2) and white-yellow (TK4) skin colour, also leaves from shoot and base. Proteases were purified through several steps consisting of extraction, precipitation using saturated ammonium sulfate and dialysis followed by electrophoresis under denaturing conditions (SDS-PAGE) and zymography. The specific activity of the four extracts showed different trend during purification. The specific activity of TK2 fruit, shoot and base leaves decreased whereas TK4 fruits increased. TK2 crude extract had a higher specific activity (3.79 U/mg) than the other crude extracts. SDS-PAGE and zymogram using 12% acrylamide indicated that the dialysates were not pure proteases. The molecular weight profiles of the TK2 dialysates were similar to TK4 dialysates, while those of shoot leaves dialysates were similar to the base leaves dialysates. The SDS-PAGE separated the enzymes in the fruit dialysates into several bands of polypeptides,i.e. 24-26kDa, 14-15kDa, 12-13kDa and the smaller ones, and also separated the enzymes in the dialysates of leaves into two bands, 70kDa and 58-61.5kDa. Protease bands detected in the zymogram of fruits were estimated at ~25kDa, ~27kDa, and 37-38kDa, whereas of those of leaves were estimated at ~29kDa and ~50kDa. The ~25kDa and ~29kDa protein bands appearing in zymogram were similar to papain’s and bromelain’s molecular weight.

Mlanding tempeh is non-soybean tempeh made from ripe lamtoro (Leucaena leucocephala) seed. In Wonogiri, an area in Indonesia, over fermented mlanding tempeh (OFMT) is often used as a seasoning for traditional food since it produces a special taste. OFMT is also dried to extend the shelf life, making it easier to use as a seasoning. This research aims to study the physical characteristics, sensory evaluation, and amino acid content of powdered over fermented mlanding tempeh (POFMT). The drying of the OFMT used a cabinet dryer with variations in drying temperatures of 55, 60, and 65°C for eight hours. Then, it was mashed and sifted to obtain POFMT. The obtained powder was then analyzed for its physical characteristics in yield, water absorption capacity, solubility, bulk density, sensory evaluation with the hedonic test, and amino acid content. This study found that different drying temperatures significantly affected the yield and water absorption but did not significantly affect the solubility and bulk density. The yield values varied between 7.06-12.92%; water absorption capacity varied between 0.36-0.55 g/g; solubility varied between 36.45-41.33%; bulk density varied between 0.38-0.42 g/mL. The sensory evaluation results showed that the panelists' preference for POFMT with variations in drying temperature was not significantly different. In addition, the amino acid content of POFMT varied between 0.99-5.43% (db), with the highest levels being glutamic acid and aspartic acid.

Tempe mlanding merupakan makanan fermentasi tradisional dari biji lamtoro atau sering disebut mlanding oleh masyarakat Jawa Tengah. Produk pangan berbahan baku lokal ini berpotensi sebagai sumber protein selain kedelai. Di Desa Pesido, Jatiroto, Kabupaten Wonogiri, terdapat beberapa pengrajin tempe mlanding diantaranya adalah usaha tempe mlanding milik Ibu Lati Winarsih dan Ibu Tarti. Secara umum masalah yang terjadi pada proses pembuatan tempe mlanding adalah proses yang masih tradisional sehingga belum ada standar atau pengukuran parameter sehingga kualitas produk tidak konsisten. Sebagai upaya untuk menyelesaikan masalah tersebut, tim pengabdian UNS telah menyelenggarakan tiga program yaitu introduksi teknologi tepat guna proses pengolahan tempe mlanding standar industri pangan, pelatihan dan penyususnan Cara Pengolahan Pangan yang Baik (CPPB). Penggunaan rak fermentasi sebagai pengganti fermentasi yang biasa dilakukan di lantai beralaskan kain terpal merupakan teknologi tepat guna yang diaplikasikan pada UKM tempe mlanding sehingga suhu fermentasi lebih stabil. Pelatihan dan penyusunan konsep CPPB dilakukan kepada pemilik UKM melalui praktik langsung. Dengan ketiga program tersebut, pemilik UKM menjadi lebih paham tentang teknik fermentasi dan produksi pangan yang sesuai standar sehingga meningkatkan konsistensi produk.

Tujuan penelitian ini adalah mempelajari pengaruh perlakuan pendahuluan terhadap sifat kimia (abu, lemak, protein, asam fitat, dan asam sianida) serta sifat fisik (derajat putih, densitas kamba, dan kelarutan) tepung kacang turi berbunga putih. Penelitian ini menggunakan rancangan acak lengkap dengan satu faktor,yaitu perlakuan pendahuluan yang meliputi: kontrol (F1), perebusan 90 menit dengan kulit (F2), perendaman 24 jam dengan kulit (F3), pengupasan kulit (F4), perebusan 90 menit kupas kulit (F5) dan perendaman 24 jam kupas kulit (F6). Hasil penelitian menunjukkan bahwa seluruh perlakuan pendahuluan menghasilkan tepung dengan kadar abu, asam fitat dan asam sianida (HCN) yang lebih rendah dibandingkan kontrol. Perlakuan pendahuluan pengupasan baik dengan maupun tanpa perebusan 90 menit dan perendaman 24 jam (F4, F5, F6) menghasilkan tepung dengan kadar lemak dan kadar protein lebih tinggi dibandingkan kontrol. Perebusan 90 menit dan perendaman 24 jam menghasilkan tepung dengan kadar lemak dan protein lebih rendah dibandingkan kotrol baik yang dikupas maupun yang tidak dikupas kulitnya (F2, F3, F5, F6). Tepung dengan kadar lemak danprotein tertinggi yaitu tepung dengan perlakuan pendahuluan pengupasan kulit (F4) dan tepung dengan kadar lemak dan protein terendah yaitu tepung dengan perlakuan pendahuluan perendaman 24 jam tanpa pengupasan kulit (F2). Penurunan kadar asam fitat dan asam sianida terbesar terjadi pada perlakuan pendahuluan perebusan 90 menit disertai pengupasan kulit (F5) sedangkan yang terkecil pada perlakuan pendahuluan pengupasan kulit (F4). Secara umum, perlakuan pendahuluan menurunkan densitas kamba dan kelarutan tepung yang dihasilkan, kecuali tepung dengan perlakuan pendahuluan 24 jam tanpa pengupasan kulit (F2) yang memiliki densitas kamba yang tidak berbeda nyata dengan kontrol. Derajat putih tepung dengan berbagai perlakuan pendahuluancukup variatif, yang paling tinggi derajat putihnya adalah tepung dengan perlakuan pendahuluan pengupasan kulit (F4) dan yang paling rendah adalah tepung dengan perlakuan pendahuluan perendaman 24 jam tanpa pengupasan kulit (F2).
