EFFECTS OF DRYING AND ENSILING METHODS ON CYANIDES CONTENTS AND CHEMICAL COMPONENTS OF CASSAVA ROOTS AND STEMS

The objectives of this experiment was to compare the drying and ensiling methods to reduce cyanides contents in cassava, as well as related nutrient components. This experiment used roots and stems of cas-sava, fermented juice of epiphytic lactic acid bacteria (FJLB) and molasses. A completely randomized design was used in this experiment for 8 treatments. The treatments were 30 o C incubator, 50 o C incubator, 70 o C oven drying, freeze drying, 2 d incubator 30 o C ensiling, 2 d incubator 50 o C ensiling, 2 w incubator 30 o C ensiling and 2 w incubator 50 o C ensiling. The contents of HCN, acetone cyanohydrin, linamarin, proximate components and in vitro dry matter digestibility were determined in each treatment. The result of this experi-ment showed that the contents of HCN and linamarin in ensiled cassava roots were lower (p<0.01) than in dried cassava roots. There were no significantly different on residual HCN among treatments in cassava stems. The content of linamarin was higher in freeze drying than that in heat drying methods (p<0.05). There was an opposite pattern of acetone cyanohydrins and linamarin content of roots and stems. The content of dry matter (DM) in 30 o C ensiling was lower than in 50 o C ensiling (p<0.05). The content of ash increased in cassava roots silage (p<0.01), meanwhile the decreasing of ether extract content was occured in cassava stem silage (p<0.01). Ensiling method was more effective to reduce cyanide than the drying method, and cassava silage showed a proper qualification as feed. Keywords: Drying, Ensiling, Cyanides, Cassav

Human Pappilomavirus Genotype in Cervical Tissue of Patients with Cervical Intraepithelial Neoplasia (CIN) 1, CIN 2, and CIN 3

Objectives: to determine the genotype of HPV in patients with precancerous lesions of cervical tissue.Materials and Methods: An observational study with cross sectional study of patients paraffin block CIN1, CIN2, CIN3 was conducted in Dr Soetomo Hospital. HPV DNA was extracted from paraffin blocks, then performed PCR and genotyping of HPV. The sample consisted of 28 patients with cervical tissue paraffin blocks CIN1, CIN2 and CIN3. Patients aged between 26-74 years (standard deviation 10,12).Results: HPV genotypes that infect patients with CIN1 were HPV16 and 18, CIN2 were HPV16 and 52 and CIN3 were HPV16, 67, and combined infection HPV16/67 and HPV52/67. HPV genotypes in a single infection were 26/28 (HPV16, HPV18, HPV52 and HPV67), and multiple infections were 2/28 (HPV16/67 and HPV52/67).Conclusion: The most dominant HPV genotypes infect patients with precancerous lesions of the cervix were HPV16, HPV67, HPV52, and HPV18

The purpose of this research was to analyze the correlation between knowledge and attitude regarding cataract surgery among senilecataract patients in Dr.Kariadi Hospital Semarang. This was an analytical study with cross sectional approach. The respondents were senilecataract patients in Dr.Kariadi Hospital Semarang. Research was held on MarchApril 2007. The data were analyzed using computer, thequestionnaire validity was checked by expert validity test and using Cronbach alfa for reliability. The result showed that there were about 50respondents who fulfilled the criteria. There was a significant correlation between knowledge and attitude regarding cataract surgery (p <0.005) with correlation coefficient r = 0.328. The knowledge levels were: 34% subjects have lack of knowledge, 38% subjects have enough,and 28% subjects were categorized into good knowledge. The attitudes of cataract surgery were: 30% subjects were categorized as lack, 38%subjects were categorized as enough, and 32% subjects were categorized as good. It was concluded that the knowledge of senile cataractpatients influence the attitude regarding cataract surgery. Despite of the correlation of this relationship is still low, so it was suggested toenhance socialization and education about cataract and the treatment in order to prevent unnecessary blindness because of cataract.Key words: knowledge, attitude, cataract surgery, senile cataracts patient

Community Structure of Bivalves in the Mangrove Ecosystem in the Teluk Buo, Bungus Sub-district,Teluk Kabung District, Padang, Sumatera Barat Province

Teluk Buo mangrove forest is one of tourist destination in the Sumatera BaratProvince. The input of pollutant originated from anthropogenic activities, however,reducing the water quality and as a consequence negatively affects the mangroveecosystem as well as the associated organisms, including bivalves. To understand thecommunity structure of bivalves in the mangrove ecosystem, a research wasconducted on February 2017. The observation of bivalve community is done bymaking line transects. There were 3 transect lines and in each line, 9 sub plots (1x1m)observed. The bivalves present in the plots were collected manually everyday for 2weeks period. Results shown that there were 6 bivalves species present, they wereGeloina erosa, Anadara antiquata, Barbatia sp., Lucinoma galathea, Chameleastriatula and Trychardium sp. with bivalves abundance was ranged from 6,667 to31,481 organisms/ha. The value of diversity index (H') was 0.2650-2.403, thedominance index (C) was 0.210-0.722 and the uniformity Index (E) was 0.059-0.563.The bivalva community structure in Teluk Buo is moderate with the dominant species(Geloina erosa) has been disturbed by the existence of ecological pressure and thedominant species causing unbalanced mangrove area. Abiotic environmental factorsinclude temperature was 29-31 0C; pH of water was 7.3-7.5, soil pH 7.1-7.2 andsalinity was 25-340/00

Pengaruh Jenis Kemasan terhadap Kondisi Penyimpanan Gabah Kering Panen, Rendemen Giling dan Beras Kepala

Aging is a natural and spontaneous phenomenon which occurs during storage of dry grain, involving physical changes and chemical that would alter the quality of the cooking, processing, taste and nutritional value as well as affect the commercial value of rice. Naturally aging takes a long time between 6-12 months so it is less economical. Aging may be accelerated by increasing the grain moisture content and storage temperature. Freshly harvested rough rice contains high moisture content ranging between 21-26% and respiration activity is still high which generate heat that can be accumulated by the packaging, so the grain temperature increases. The purpose of this study was to determine the types of packaging which can increase the temperature and RH storage, milling yield and head rice yield. Grain varieties used are Siam Pandak with five types of packaging, ie black plastic bags, sacks, cans, wood and tarpaulin, and stored for 72 hours. As a control, direct drying grain harvest is used. Observations are including temperature and RH in packaging, milling recovery and head rice yields. The results showed that all types of packaging used can increase the temperature and RH in the packaging than the temperature and RH in storage space. The most high milling recovery obtained from black plastic packaging, while the head rice yields all kinds of packaging meets the quality criteria V ISO 6128-2008 except wood packaging, although based on the percentage of head rice, tarpaulins packaging has the highest head rice
