Disorder of carbohydrate metabolism in the Diabetes Mellitus patients resulted in increasing of cholesterol synthesis. This condition increases the risk of heart attack or coronary heart disease, therefore it is recommended to lower fat intake. One of the alternatif to lower fat intake is by replacing fat with fat replacer in the diet. The aim of the present study is to evaluate the effect of replacing 75% of fat with SOPE on the glucose and lipid profile in diabetic-hipercholesterolemic rats. Eihgteen Sprague Dawley rats were devided into 2 groups of 9 rats. They were fed with hipercholesterol diet and were diabetic induced with alloxan IM injection. One group was fed with 75% SOPE substitute the fat in the standard diet and the other group was fed with standard diet. The result indicates that the oil substitution of standard diet of Sprague Dawley rats for sorbitol-oleic polyester as much as 75% gives an advantage to rats which suffer hiperglikemic-hypercholesterolemic because it decreased the glucose, total cholesterol, LDL cholesterol, and LDL/HDL cholesterol ratio, and did not decrease the HDL cholesterol, but increased triglyceride serum.

An indigenous strain of lactic acid bacterium (LAB) identified as Lactobacillus spp. Dad13 (Dad13), isolatedfrom traditional fermented buffalo milk, was found to be potential as probiotic. The aim of this research was to studythe effect of probiotic Dad13 on humoral immune response of Balb/C mice infected with Salmonella typhimurium. Thespecific objective was to find out the effect of different Dad13 consumption time (before and along with infection of S.typhimurium) on the humoral immune response of Balb/C mice. The experiment was conducted by in vivo trial on 20males of Balb/C mice, age of 6-8 weeks, fed with AIN-93 standard diet. The mice were assigned into 4 groups. Eachgroup received the following treatments, ie. Dad13 only, Dad13 before infection, Dad13 along with infection andSalmonella infection only. A volume of 100 μl Dad13 cell suspensions (1010 CFU/ml) were given by oral forced feedingdaily for a week, at week 3 for group before infection and at week 4 for group of Dad13 only and Dad13 along withinfection. Salmonella infection (109 CFU/ml) was given once orally at week 4 to all groups except group treated withDad13 only. The humoral immune response of Balb/C mice was detected 2 weeks after infection by measuring thetiters of IgG and IgA specific from serum and mucosal intestinal liquid samples using Enzyme-linked ImmunosorbentAssay (ELISA) method. The result indicated that humoral immune response of Balb/C mice consuming Dad13 beforeand along with Salmonella infection were significantly different (p<0.05). Dad13 consumption along with Salmonellainfection increased circulated IgG and IgA as well as secretory IgA. It can be concluded that Dad13 probiotic feedingalong with infection increased humoral immune response more significantly compared to that before infection.Key words : Probiotic, Lactobacillus sp. Dad13, Immune response, Salmonella typhimurium

Background: Macrophages play an important role as part of the innate immune response in the gut and they represent one of the first lines of nonspecific defense against bacterial invasion. Previous studies indicated that probiotics and prebiotics may act as an immunomodulator agents. Nevertheless, research on the immunomodulatory effect of local materials has never been performed.Objective: To study the effects of Lactobacillus plantarum Mut7 and sweet potato fiber on the activity and Nitric Oxide (NO) production of peritoneal macrophages of Sprague Dawley rats.Method: Ninety six Sprague Dawley rats aged 8 weeks were divided into two groups; A (not infected with Salmonella typhimurium) and B (infected with S. typhimurium). Each group was divided into 4 subgroups and assigned to standard AIN-93M diet (KON), 109 CFU/ml of L. plantarum Mut7 (PRO), modified AIN-93M diet with sweet potato fiber (PRE), and both component (SIN). After 3 weeks of treatment, 6 rats of each subgroup were sacrificed and the peritoneal macrophages were isolated and analysed for its activity and NO production. The rest of the rats continued the treatments for another 2 weeks. At the end of the experiment, they were sacrificed and the peritoneal macrophage were isolated and analysed for its activity and NO production.Results: Oral administration ofÂ L. plantarum Mut7, sweet potato fiber, or both improve phagocytic activity of peritoneal macrophage which was indicated by an increase in the percentage of macrophages that phagocyte latex particles (p<0.05) and an increase in the number of latex particles engulfed by macrophages either after 3 or 5 weeks of treatment (p<0.05). Oral administration of L. plantarum Mut7, sweet potato fiber, or both were unable to increase the nitric oxide production after 3 weeks of treatment (p>0.05), but after 5 weeks of treatment the production of NO was significantly increased (p<0.05).Conclusion: L. plantarum Mut7, sweet potato fiber, or both increase the non specific immune response as they could improve the activity and NO production of peritoneal macrophages.

ABSTRAKÂ Jagung merupakan salah satu komoditas pertanian yang berpotensi besar untuk dikembangkan secara komersial. Cookies yang dibuat dari 100% tepung jagung mengakibatkan penerimaan konsumen yang menurun karena tekstur cookies yang keras. Kekerasan pada cookies dari jagung dapat pula disebabkan oleh kemampuan pati dalam mengikat air dan lemak yang rendah serta struktur pati yang kompak. Salah satu metode modifikasi pati yang digunakan untuk memperbaiki sifat pati adalah asetilasi. Persyaratan derajat asetilasi pada pati yang dapat digunakan untuk menjadi produk olahan adalah 0,01-0,2. Tujuan dari penelitian ini adalah mendapatkan rekayasa proses asetilasi untuk mendapatkan derajat substitusi 0,2 dan mengetahui perubahan karakteristik fisikokimia, hidrofobisitas dan kristalinitas pada pati dengan derajat substitusi 0,2. Jagung varietas Bisi-18 yang digunakan untuk penelitian berasal dari Kabupaten Bantul, Yogyakarta. Tahapan penelitian meliputi ekstraksi pati jagung dan modifikasi asetilasi dengan Rancangan Acak Kelompok. Faktor 1 adalah konsentrasi asetat anhidrat (2,4,6%) dan faktor 2 adalah waktu reaksi (5,10,15 menit). Hasil penelitian menunjukkan bahwa proses asetilasi terjadi pada pH 8-8,4; suhu reaksi 28-30oC selama 15 menit dengan konsentrasi asetat anhidrat 4% (v/w) menghasilkan pati terasetilasi dengan derajat subtitusi 0,2. Pati jagung tersebut mengalami perubahan karakteristik yaitu lebih hidrofob dan kristalinitas menurun. Pati terasetilasi dengan derajat substitusi 0,2 berpotensi untuk dijadikan bahan baku kue kering seperti cookies.ABSTRACTÂ Corn is one of the agricultural commodities with great potential to be developed commercially. Cookies from 100% corn flour resulted in reduced consumer acceptance, caused by hard cookies. The hardness of the cookies from corn can also be caused by the low ability of starch to binding water and fat, and the compact structure of starch. One of the starch modification methods used to improve starch properties is acetylation. The degree of acetylation in starch that can be used to be a processed product is 0.01-0.2. The aims of this study were obtaining an acetylation process to obtain a degree of substitution of 0.2 and to determine the changes in the characteristics of physicochemical, hydrophobicity, and crystallinity of starch with a degree of substitution of 0.2. Corn variety Bisi-18 used for research comes from Bantul Regency, Yogyakarta. The research stages included extraction of corn starch and modification of acetylation with a randomized block design. The first factor was the concentration of acetate anhydrous (2,4,6%) and the second factor was the reaction time (5,10,15 minutes). The results showed that the acetylation process occurred at pH 8-8.4; reaction temperature is 28-30oC for 15 minutes with Â 4% (v/w) acetate anhydrous to produce degree of substitution 0,2 acetylated corn starch. The characteristic of degree of substitution 0,2 acetylated corn starch is more hydrophobic and decreased crystallinity compared to natural starch. Acetylated starch with degree of substitution 0,2 has potential to be used as raw material for pastries such as cookies.

The most popular Indonesian native chicken, known as kampung chicken, is maintained under free-range conditions therefore it is prone to high environmental stress. Indonesian native chicken and its product are always regarded as having health benefits compared to commercial chicken by Indonesian society. But there is still limited report regarding Indonesian native chicken and its product. This study focused on screening immunostimulatory activity from Indonesian native chicken egg white using in vitro approaches as a functional food. Indonesian native chicken egg white (NEW) was extracted using distilled water supplemented to human-human hybridoma HB4C5 cells to examine the IgM production stimulating activity using ELISA. The gene expression was also examined using qRT-PCR. The ability of NEW on stimulating immunoglobulin production by mouse splenocytes was analyzed. Commercial egg white water extract (CEW) was used as a comparison. The data were analyzed using One-way ANOVA and continued by using post-hoc analysis using Tukeyâ€™s multiple comparison test. The results showed that NEW and CEW modulated IgM production by the HB4C5 cells 8.72-fold and 6.75-fold, respectively, compared to control. NEW stimulated immunoglobulin (Ig) production by the mouse splenocytes higher than CEW. To conclude, NEW provides an immunostimulating activity that can potentially act as a health-promoting food.

Effect of jelly containing of porang (Amorphophalus oncophyllus) glucomannan and inulin as a snack to the body weight, BMI, body fat, total cholesterol, and triglyceride levels in obese adultBackground: Obesity is a major risk factor for noncommunicable diseases, especially cardiovascular disease. Porang glucomannan and inulin are water-soluble fibers that have been widely studied for their health benefits. Jelly products that contain both types of fiber are expected to have the ability to support the diet program in adults with obese nutritional status. Objective: To determine the effect of giving jelly containingÂ a combination of glucomannan porang and inulin on body weight, BMI, body fat, total cholesterol, and triglyceride levels in obese adults.Methods: This research is a randomized controlled trial using a pre and post-test design. A total of 55 subjects who live in the Special Region of Yogyakarta, participated in the study until the end of 8 weeks. Subjects were divided into 3 groups; 18 people in the group who were given jelly containing glucomannan porang and inulin (porang-inulin jelly group), 17 people in the group who were given placebo jelly (placebo jelly group), and 20 people in the negative control group who did not get jelly (negative control group). All subjects received a low-calorie diet intervention of 1,500 kcal in the first month and 1,200 kcal in the second month. Results: There was a significant reduction in body weight and BMI (p<0.05) in all groups, but there was no difference in the effect between the porangâ€“inulin jelly group and the other groups (p>0.05). Clinically, there was a significant decrease in body fat percentage in the porang-inulin jelly group, in subjects with the category of an excess fat percent (-0.90 Â± 0.49%) and obesity (-1.48 Â± 0.83%). A significant decrease in fat percentage also occurred in the porang-inulin jelly group, both in male subjects (-1.42 Â± 0.50%) and female (-1.15 Â± 0.82%), while in the placebo jelly group and negative control, the decrease did not occur in all categories and genders. There was an increase in total cholesterol levels in the negative control group (p<0.05) after the study (+7.45 Â± 13.18 mg/dL). In the porang-inulin jelly group, the increase in cholesterol levels did not occur significantly either in general or based on clinical categories and gender. Conclusion: Consumption of porang-inulin jelly may support weight loss programs, BMI, percent body fat, and inhibit the increase of total cholesterol and triglyceride levels in adults with obese nutritional status.

Arrowroot (Maranta arundinacea L.) is a multipurpose plant that can grow under the stands so that the species has the potential to develop in the pattern of agroforestry. Initial information of arrowroot plant population as a source of germplasm for plant material/superior varieties and their agroecological characteristics in the field is indispensable. The study aims to determine the distribution, agroecological characteristics and potency of arrowroot in Garut regency. The methods include: (1) the study of literature and direct communication with stakeholders and the public, (2) field survey to collect data on distribution, cultivation status, abundance and productivity of arrowroot plant using a single plot, and (3) data collection of arrowroot agroecological characteristics include: vegetation analysis and geoklimat factors. The research results indicate that the arrowroot populations distribute in groups with a fairly broad ecological range i.e. altitude 6-1351 masl, temperature 20-36o C, relative humidity RH 40-72%, light intensity 12-56% dan pH 4.16-7,40 (acid to neutral) and in the low to high soil fertility condition. Falcataria moluccana as the major private forest species dominates in all zones of altitude, especially on the stage of the tree. Arrowroot abundance by elevation zones is 63,750 plants/ha (lowlands), 43,864 plants/ha (plains) and 73.333 plants/ha (plateau). The potential production for all elevations ranged from 15.40 to 163.2 g/plants. Cikajang and Cilawu populations have good potential to produce the high yield of tuber for arrowroot cultivation in Garut District.
