Dwi Budi SANTOSO(Dwi Budi SANTOSO ),Dynda Fadhlillah AULIA(Dynda Fadhlillah AULIA ) 한국유통과학회 2023 The Journal of Asian Finance, Economics and Busine Vol.10 No.1
There is a strong association between poverty levels and the probability of natural disasters. East Java, however, exhibits a distinct pattern. While the rate of poverty is declining, natural disasters are becoming more severe. Considering that East Java is an area with a high risk of natural disasters and a high poverty rate, this study aims to estimate the effect of environmental preservation and the magnitude of the impact of disasters as measured by the Disaster Risk Index (IRBI) on poverty. The 3SLS model is used on secondary data from 38 districts/cities from 2015 to 2021 as an analytical database. Based on the estimation results, there are 3 findings in this study: (i) the role of government, population development, and economic activity have a strong influence on nature conservation; (ii) nature conservation has a strong influence on disaster risk; and (iii) the disaster risk index has a strong effect on poverty. As a result, areas with a high level of disaster risk have a slower rate of poverty reduction. The role of this research is to show the need for the government’s role in improving the quality of natural disaster mitigation anticipation, economic activity, and the role of the population in a sustainable manner.

In a balanced incomplete block design, two dry Holstein cows were used to investigate the effect of $\beta$ 1-4 galactooligosaccharides (GOS) supplementation on nitrogen (N) utilization, rumen fermentation and microbial N supply in the rumen. During the experiment, cows were fed four diets: orchardgrass (Dactylis glomerata L.) silage (OS), OS with GOS supplementation (OSG), OS mixed with alfalfa (Medicago sativa L.) silage (MS) and MS with GOS supplementation (MSG). GOS was supplemented at 2% of dry matter intake. Diets were fed at maintenance level of protein and energy. Results showed that N digestion was affected by silage and interaction of silage and GOS supplementation. Cows fed OSG had the highest N digested (p<0.05) followed by MS, OS and MSG. Supplementation of GOS to OS or MS diets tended to improve N utilization through reducing the N losses on dairy cows. There was no effect of GOS supplementation on rumen fermentation parameters (i.e. pH, $NH_3$-N and total VFA) at 1 h and 6 h after feeding. Compared to cows fed MS, cows fed OS silage had higher (p<0.05) allantoin excretion (80.8 vs. 67.1 mmol/d) and higher (p<0.05) total purine derivatives excretion (92.9 vs. 78.5 mmol/d). The microbial N supply in cows fed OSG was higher (p<0.05) than those fed OS, MS and MSG.

The present study was conducted to evaluate effect of Sauropus androgynus extract (SAE) on egg production and lipid metabolism in layer chickens. Forty-eight layers aged 42 weeks (strain RIR) were distributed to 6 treatment groups as follows. One group was fed diet without SAE as the control ($P_0$), and other five groups were fed diet plus hot water-extracted SAE at level of 9 g/kg diet ($W_9$), diet plus ethanol extracted SAE at level of 0.9 g/kg diet ($E_{0.9}$), diet plus ethanol extracted SAE at level of 1.8 g/kg ($E_{1.8}$), diet plus methanol extracted SAE at level of 0.9 g/kg ($M_{0.9}$), and diet plus methanol extracted SAE at level of 1.8 g/kg ($M_{1.8}$). It was shown that SAE inclusion significantly increased egg production (p<0.05). Methanol-extracted SAE groups had lower egg production than ethanol-extracted SAE group (p<0.05). SAE supplemented groups had better feed conversion efficiency than the unsupplemented group (p<0.05). It was shown that ethanol extracted SAE resulted in the lowest feed conversion efficiency among the SAE supplemented groups (p<0.05). SAE supplementation significantly reduced abdominal fat, gizzard surrounded fat, liver fat (p<0.05), serum triglyceride, total cholesterol, VLDL+LDL-c (p<0.01), atherogenic index (p<0.05), egg cholesterol and triglyceride (p<0.05), but it had no effect on mesenteric fat, sartorial fat and fatty liver score. In conclusion, SAE supplementation could increase egg production but reduced egg cholesterol.

This study was conducted to investigate the effect of supplementation of galacto-oligosaccharides (GOS) on methane emission, nutrient digestibility, energy utilization and blood metabolites by Holstein cows fed silages. In two sequential digestion and respiratory trials, two non-lactating Holstein cows were arranged to a balanced incomplete block design. Experimental diets consisted of two silage types; orchardgrass (Dactylis glomerata L.) based silage (OS), mixed silage (orchardgrass based silage and alfalfa (Medicago sativa L.) silage) (MS), while two GOS levels were without supplementation (0) and 2% of dry matter intake supplementation (2). Four combination diets were OS-0, OS-2, MS-0 and MS-2. Significant effects of silage types and GOS supplementation levels were not observed for DM and OM intake. Whereas the digestibility of OM, NDF and ADF was significantly (p<0.05) higher in cows fed OS with and without GOS compared cows fed MS diets. As percentage of GE intake, fecal energy loss for OS diets was significantly (p<0.05) declined than for MS diets. In contrast, cows fed MS diets had lower (p<0.05) urine energy loss as a proportion of GE intake compared to OS diets. Energy loss as CH4 and heat production was numerically increased when cows fed both OS and MS with GOS supplementation. Compared to OS, CH4 emission in cows fed MS was numerically decreased by 10.8 %. Methane conversion ratio (energy loss as CH4 per unit of GE intake) for OS-0, OS-2, MS-0 and MS-2 were 7.1, 7.2, 6.8 and 7.0, respectively. Plasma of glucose and urea-N concentration were significantly (p<0.05) elevated from 1 h to 6 h after feeding, otherwise total protein in plasma was declined (p<0.01) at 6 after feeding.

This study investigated the effects of fermented product from Bacillus subtilis (FPBS) on feed conversion efficiency, fat accumulation and ammonia production in broiler chicks. Sixty female broilers (strain Chunky, 7-day old) were divided into four groups and raised in individual cages. One group was fed a commercial diet without supplementation of FPBS as the control and the other three groups were fed commercial diets containing FPBS, either 0.5, 1.0 or 2.0%, for 21 days from 7 to 28 days of age. Water and feed were given ad libitum. Feed conversion efficiency was significantly improved in chicks supplemented with 0.5 or 1.0% of FPBS as compared with the control (p<0.05). The activities of hepatic acetyl-CoA carboxylase and fatty acid synthetase, and contents of triglyceride and cholesterol in the liver were significantly decreased in treatment groups (p<0.05) as compared with the control group. FPBS had no effect on the concentration of plasma triglyceride, phospholipids and cholesterol. Feeding FPBS at 1 % or 2% levels reduced ammonia gas release (p<0.05). The inclusion of FPBS at 1 % level may be recommended both to improve production efficiency and to reduce air pollution caused by ammonia gas release. For production efficiency to reach maximal profit, the inclusion of FPBS at 0.5% level can be recommended. Feeding FPBS reduced fat accumulation in the liver.

The present study was conducted to evaluate the effect of early feed restriction on growth, fat accumulation and meat composition in unsexed broiler chickens. Five hundred 7-day old unsexed broiler chickens were distributed into ten treatment groups with 5 pens of 10 broilers each group. One group was fed ad libitum as the control group and other nine groups were fed 25% ad libitum for 3, 6 or 9 days, 50% ad libitum for 3, 6 or 9 days, and 75% ad libitum for 3, 6 or 9 days, respectively. Thereafter, they were fed ad libitum to 56 days of age. The present results showed that broilers showed compensatory growth when they were restrict-refed. Feed conversion ratio was significantly lower in broilers fed 25% ad libitum for 9 days (p<0.05). Triglyceride concentration of serum was significantly lower in restricted unsexed broilers (p <0.01), whereas cholesterol concentration was not significantly different. Abdominal fat was significantly lower in broilers fed 25% ad libitum for 9 days, 50% ad libitum for 3 days and 75% ad libitum for 6 or 9 days (p<0.05). Moisture and protein contents of meats were not significantly affected. Ash content of meat was significantly higher in restricted broilers. Fat content of meat was lower in broilers fed 25% ad libitum for 9 days, 75% ad libitum for 3 to 9 days. In conclusion, broilers showed compensatory growth when they were restrict-refed at an early age. In order to achieve the success of early feed restriction (namely reduce fat accumulation and improve feed conversion ratio with comparable body weight at market age), unsexed broilers should be fed at level of 25 ad libi=tum for 9 days starting at 7 days of age.

Santoso Handri,Shusaku Nomura,Kazuo Nakamura 한국지능시스템학회 2010 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.10 No.1
Final year students are normally encountering high pressing in their study. In view of this fact, this research focuses on determining mental states condition of college student in final year based on the psycho-physiological information. The experiments were conducted in two times, i.e., prior- and post- graduation seminar examination. The early results indicated that the student profile of mood states (POMS) in prior final graduation seminar showed higher scores than students in post final graduation seminar. Thus, in this research, relation between biosignal representing by heart rate variability (HRV) and questionnaire responses were evaluated by hidden Markov model (HMM) and neural networks (NN).
