PENDAMPINGAN USAHA PRODUK MAKANAN BEKU BERBAHAN DAGING AYAM DI KELURAHAN OESAPA KUPANG NTT DI MASA PANDEMI COVID-19

Masa pandemi covid-19 membuat ruang gerak masyarakat terbatas untuk membeli makanan di warung atau di pasar, sehingga produk pangan beku berbahan daging ayam dapat menjadi pilihan, karena praktis, dapat disimpan lama dan bergizi. Namun, permasalahan dari kelompok mitra yaitu: 1) minimnya pengetahuan untuk membuat berbagai variasi produk makanan beku berbahan daging ayam, 2) kurangnya permodalan untuk melakukan usaha kuliner berbahan daging ayam, 3) kurangnya motivasi untuk menjual produk beku berbahan daging ayam. Metode 1) Memberikan bantuan karkas ayam dan paket bantuan alat dan bahan pengolah produk daging ayam, 2) memberikan penyuluhan 3) melakukan pendampingan kegiatan kepada ibu-ibu, dan melakukan evaluasi setiap kegiatan agar ibu-ibu dapat mandiri dan usaha berkelanjutan. Simpulan: 1) Bantuan modal berupa karkas ayam dan peralatan dapat membantu ibu-ibu untuk memproduksi frozen food, 2) Pelatihan wirausaha tentang keuntungan usaha penjualan produk beku berbahan daging ayam, 3) Penyuluhan tentang protein hewani dapat menyadarkan masyarakat untuk meningkatkan konsumsi daging ayam. Kata kunci : daging ayam, makanan beku, karkas, pandemi ABSTRACT During the COVID-19 pandemic, people have limited space to buy food in stalls or at the market, so frozen food products made from chicken meat can be an option, because they are practical, can be stored for a long time  and are nutritious. However, the problems of the partner group are: 1) lack of knowledge to make various variations of frozen food products made from chicken meat, 2) lack of capital to conduct a culinary business made from chicken meat, 3) lack of motivation to sell frozen products made from chicken meat. Methods 1) Provide assistance with chicken carcasses and packages of tools and materials for processing chicken meat products, 2) provide counseling, 3) provide assistance for activities to partners, and evaluate each activity so that partners can be independent and have a sustainable business. Conclusions: 1) Capital assistance in the  form of chicken carcasses and equipment can help partner to produce frozen food, 2) Entrepreneurship training on the benefits of selling frozen products made from chicken meat, 3) Counseling on animal protein can make people aware of increasing consumption of chicken meat.

NTPase and 5′-RNA Triphosphatase Activities of Chikungunya Virus nsP2 Protein

Chikungunya virus (CHIKV) is an insect borne virus (genus: Alphavirus) which causes acute febrile illness in humans followed by a prolonged arthralgic disease that affects the joints of the extremities. Re-emergence of the virus in the form of outbreaks in last 6–7 years has posed a serious public health problem. CHIKV has a positive sense single stranded RNA genome of about 12,000 nt. Open reading frame 1 of the viral genome encodes a polyprotein precursor, nsP1234, which is processed further into different non structural proteins (nsP1, nsP2, nsP3 and nsP4). Sequence based analyses have shown helicase domain at the N-terminus and protease domain at C-terminus of nsP2. A detailed biochemical analysis of NTPase/RNA helicase and 5′-RNA phosphatase activities of recombinant CHIKV-nsP2T protein (containing conserved NTPase/helicase motifs in the N-terminus and partial papain like protease domain at the C-terminus) was carried out. The protein could hydrolyze all NTPs except dTTP and showed better efficiency for ATP, dATP, GTP and dGTP hydrolysis. ATP was the most preferred substrate by the enzyme. CHIKV-nsP2T also showed 5′-triphosphatase (RTPase) activity that specifically removes the γ-phosphate from the 5′ end of RNA. Both NTPase and RTPase activities of the protein were completely dependent on Mg2+ ions. RTPase activity was inhibited by ATP showing sharing of the binding motif by NTP and RNA. Both enzymatic activities were drastically reduced by mutations in the NTP binding motif (GKT) and co-factor, Mg2+ ion binding motif (DEXX) suggesting that they have a common catalytic site

One of the impacts of the natural disaster is the disruption of food supply. The community is required to be able to take advantage of potential local resources, including Moringa leaves which are rich in nutrients and are widely available in almost all places in the city of Kupang. However, the partner group does not use Moringa leaves as a potential local feed raw material, and lacks understanding about providing emergency food stocks that are nutritious and can last a long time. Based on the analysis of the problem above, it is felt necessary to provide training in processing Moringa leaves into healthy snacks that are rich in benefits. The methods are counseling, consultation, diffusion of science and technology, and training. The results of this activity are increasing the knowledge and skills of partners in utilizing local superior commodities, namely Moringa leaves. In conclusion, the partner group was able to utilize Moringa leaves to be used as raw materials for making protein bars as healthy, practical, long-storage, and nutritious snacks Keywords: protein bar, moringa leaves, snack, emergency food, seroja cyclo
