Abstract

Research was objected to determine the effect of patchouli leaves preparation on the distillation efficiency and quality of patchouli oil. The patchouli leaves (Pogostemon cablin Benth) were taken from Pandan Dulang Village, Muara Enim. It was separated from the stems and dried until maximum moisture content of 15%. Experiment was conducted in two replications base on these treatments, i.e delignification temperature (550C, 800C) and fermentation time (2, 4, 6, 8, days). NaOH solution (0,25%) was used for delignification. The distillation process was conducted at 100  20C and ambient pressure environment. Patchouli oil quality was expressed as several parameter such as ester numbers, acid numbers, and specific gravity. The result showed that increasing of fermentation time is followed by decreasing of the patchouli oil quality. Delignification at 550C for 6 days was identified as the treatment produced the highest efficiency process which about 2,346% (w/w) of patchouli oil that could be extracted and showed specific gravity 0.959, acid number 0,761 and ester number 4,561. All patchouli oil produced using the treatment of fermentation time were in the range of physico-chemical quality standard of patchouli oil given by SNI no 06-2385-1991.

Abstract

Riswandi et al, 2018. Physical Quality Evaluation and Palatability of (Hymenachne acutigluma) through Combination of Palm Oil and Cassava Leaves. JLSO 7(2):204-212. The aim of this study to investigate the physical quality and palatability based feed Hymenachne acutigluma which is combine cassava leaves and palm oil as animal feed.  This reseach   was done in 3 months in Cattle Nutrition and Feed Laboratory and Livestock Experiment Studies Program Faculty of Agriculture, University of Sriwijaya.  This reseach used completely randomazed design method with 4 treatments and 4 replications.  The treatment consisted of R0 (85% Hymenachne acutigluma + 15% concretate), R1 (55% Hymenachne acutigluma + 30% cassava leaves + 15% concrentate), R2 (55% Hymenachne acutigluma + 30% palm oil + 15% concentrate), R3 (55% Hymenachne acutigluma + 15% cassava leaves + 15% palm oil + 15% concentrate).  The observed variabels are smell, water ration, density and palatability of feed consisted.  The results showed thet the treatment had significant effect (P<0.05) on density of the ration and had no significant effect (P>0.05) on the smell and the water content of the feed.  The result of the palatability rations show thet the treatment of R1 is the most favored by the livestock.  The conclusion of this reseach is indicate that the combination 55% Hymenachne acutigluma + 30% cassava leaves + 15% concrentate can improve the physical quality and palatability.

Abstract

Skim milk homogenization at 7 (single stage), 71 and 176 kg/cm2(dual stage,35 kg/cm2 second stage )Was used in the manufacture of cottage cheese. Each lots of skim milk manufactured into cottage cheese was inoculated with lactic culture M37.Bulk stater of lactic culture M30 was homogenized at 0,35(single stage ),106,and 246 kg/cm2 (dual stage 35kg/cm2 second stage).the use of 4 deifferent bulk culture with 3 different skim milk treatment produced a total of 12bulk starter skim milk treatment combinations. All 12 bulk starter skim milk treatment combinations were randomized prior to their manufacture. The experiment was relicated four time to manufacture of 48 vats of cottage cheese. Either homogenization of skim milk at 71 kg/cm2(dual stage, 35kg/cm2second storage)or greater or homoginezation of bulk culture at 246kg/cm2(dual stage, 35kg/cm2second storage) reduced yield loss

Abstract

Lactobacillus sp B441 and II442 were species of lactic acid bacteria isolated from tempoyak, a kind of food fermented made from durian flesh. Staphylococcus aureus is a pathogenic bacteria that has natural habitat on the surface of human body such as on the skin and in mucous membranes like the nose. Contamination of Staphylococcus aureus was a risk factor in tempoyak fermentation, especially, during taking the durian flesh from seeds. The aim of this research was to observe antagonistic property of Lactobacillus sp B441 and II442 isolated from tempoyak during low temperature fermentation against Staphylococcus aureus. Phenotypic identification using API 50 CHL test kit indicated that isolates were Lactobacullus plantarum B441 and Lactobacillus plantarum II442. Based on co-culture analysis show that isolates of Lactobacillus plantarum B441 and II442 have bactericidal effect against Staphylococcus aureus ATCC 25923 as a indicator of pathogenic bacteria. At 25 th hours, population of Staphylococcus aureus ATCC 25923 in mix-culture with Lactobacillus plantarum B441 and Lactobacillus plantarum II442 decreased 3 – 4 log cycle from initial population. However, population of Staphylococcus aureus ATCC 25923 in mono-culture increased 2 log cycles at 25 th hours.  ABSTRAKLactobacillus sp B441 dan II442 merupakan spesies bakteri asam laktat yang diisolasi dari tempoyak yaitu makanan fermentasi dari daging buah durian. Staphylococcus aureus adalah bakteri patogenik yang habitat alaminya pada permukaan kulit manusia dan membran mukosa seperti hidung. Proses fermentasi tempoyak khususnya saat pemisahan daging buah durian dari bijinya beresiko terkontaminasi oleh Staphylococcus aureus. Tujuan dari penelitian ini adalah mengkaji sifat antagonistik dari Lactobacillus sp B441 and II442 yang diisolasi dari tempoyak terhadap Staphylococcus aureus. Identifikasi secara fenotif menggunakan API 50 CHL test kit menunjukkan bahwa isolat bakteri asam laktat tersebut adalah Lactobacullus plantarum B441 dan Lactobacillus plantarum II442. Berdasar uji co-culture diketahui bahwa kedua spesies tersebut mempunyai efek bakterisidal terhadap bakteri Staphylococcus aureus ATCC 25923. Pada jam ke 25 Staphylococcus aureus yang ditumbuhkan secara mix-culture dengan Lactobacillus plantarum B441 dan Lactobacillus plantarum II442 asal tempoyak turun 3 – 4 log cycle dari populasi awal. Sedangkan populasi Staphylococcus aureus ATCC 25923 secara mono-culture meningkat sekitar 2 log cycle pada jam ke 25.

Abstract

Edible film from ganyong starch without and with modification were incorporated by CMC and lecithin as surfactants. Edible film were characterized with respect to water vapor transmission rate and mechanical properties. Incorporation of CMC 2 % and lecithin 1 % as surfactants decreased water vapor transmission rate. Puncture strength decreased but still fulfill Japanese Industrial Standard (JIS) 1975 min 50 gf.  Elongation of edible film increased and not fulfill JIS 1975 min 70 %.ABSTRAKEdible film pati ganyong sebelum dan setelah dimodifikasi ditambahkan surfaktan CMC dan lesitin. Karakteristik edible film yang diamati adalah laju transmisi uap air dan sifat mekanik (kuat tekan dan persen pemanjangan). Penambahan CMC dengan konsentrasi 2 % dan lesitin 1 % menurunkan laju transmisi uap air edible film pati ganyong. Kuat tekan edible film pati ganyong mengalami penurunan, namun masih memenuhi standar JIS 1975 minimal 50gf. Nilai persen pemanjangan edible film pati ganyong meningkat tetapi belum memenuhi standar JIS 1975.
