Abstract
While frost is a natural phenomenon in Hungary from autumn to spring, the frost damage, causing crop damage and yield reduction or even harvest shortfall, does not occur every year. The aim of the study was to estimate the occurrence and frequency of frost damage in fall, winter and spring frost damage from the CarpatClim data base, in the wine regions of Hungary. Determining the daily distribution of the LT50 function between September 7 and May 15, with the Cold Hardiness model which contains 23 grape varieties, the occurrence probability of fall, winter and spring frost damage can be accurately determined. The extent of frost damage, frost duration and strength of frost is significantly affected by tolerance of grape varieties. We analysed the extent of fall, and spring frost damage respectively at frost susceptible, moderately frost-tolerant and frost-tolerant grape varieties. We examined the stepovers of frost damage thresholds by using CARPATCLIM database during the period between 1961-2010. The results provide not only frost damage quantification, but they may also help to judge the complex value of cultivation areas more accurately and to parameterize the crop safety of wine regions.

Abstract
Chinese restaurants in Bandung existed since the colonial era. Customer satisfaction in a restaurant is influenced by factors including ambiance. This paper studied the important of ambiance in visitors- choice to a Chinese restaurant using 3 study cases. The method used were field observation, visual documentation, and questionnaire. Research finding was that ambiance was placed the third factor out four with level of importance at 58.8%, less significant than food (80,4%). However, when visitors were asked their visual preference and ideas on how a Chinese restaurant should be, they prefer a thematic restaurant with traditional ambiance.

Abstract
Introduction. The previous investigation was reported in an area with mental retardation due to iodine deficiency disorders (IDD) in Ponorogo. Lack of environment iodine and water contamination of heavy metal need to describe related to IDD in Ponorogo. This contamination caused the risk of inhibition of nutrient intake in exposed plants. Objective. The aim of study was to investigate iodine deficiency disorders, blocking agent, ferritin status and goitrogenic consumption in a peripheral endemic area of IDD area in Ponorogo. Method. This was a cross-sectional study that was conducted in Dayakan and Watubonang Village. Ponorogo. Household that had childbearing women age (CBW), school-aged children 9-11 years old (SAC) and children under five (CUF) were selected as sample. The number of samples in both areas was 118 CBW; 124 SAC, and 123 CUF. About 29 soil and 87 water samples were taken to measure iodine and heavy metal such as: mercury (Hg) and lead (Pb) concentration. Iodine status was determined by median urinary iodine concentration of casual urine sample that measured via spectrofotometry method. Thyroid function diagnosis was carried out through various of test: Thyroid Stimulating Hormone (TSH) and free-Tetraiodothyronine (fT4) by Enzyme Linked Immunosorbent Assay (ELISA). Ferritin contents were measured by the ELISA method. Goitrogenic consumption through semi-quantitative food frequency interviews. Results. Median Urinary Iodine Concentraion (UIC) of CBW and SAC were 105 and 121.5ug/L, respectively. Overall mean of iodine concentration in soil and water were 36.74mg/Kg and 13.6ug/L respectively, Dayakan 25.68mg/Kg and 0.6ug/L, Watubonang 54.83mg and 19.5ug/L. Overall, mean of Hg soil was 96.46mg/kg; Dayakan was 86.32mg/Kg; Watubonang 113.06mg/Kg, and < 1ppb in water both areas. Mean of Pb in soil was 5.81mg/Kg. Dayakan was 4.35mg/Kg; Watubonang 8.19mg/Kg, while not detected in water in both area. Hypothyroid in CBW, SAC and CUF in Dayakan 38.1%; 27.9%; 17.9% and Watubonang 7.3%; 14.3%;17.9%, respectively. Overall goitrogenic consumption in respondent who have hypotiroidism at cassava in 1-3 times/day : 31,5%. Cabbage in 1-3 times / week : 34,8%, green cabbage 1-3 times : 41.2%. Cassava leaves in 1-3 times / week :1,5%. White mustard 1-3 times / week : 27,0%. That respondents with ferritin deficiency were 25.8% in Dayakan Village, and 19.8% in Watubonang Village. The proportion of people with ferritin deficinecy in Dayakan Village was 1.4 times than in Watubonang Village. Conclusion. Overall, thyroid function disorder was found in both areas despite iodine status of population showed in normal value. Dayakan was lower iodine environment status than Watubonang. Heavy metal concentration was obtained in Watubonang higher than Dayakan. The IDD and anemia control program should be undertaken to prevent future public health problem in both areas.

Abstract
The aim of this study was to examine the effect of VOC exposure from cigarette smoke on the plant growth regulator (PGR) patterns consisting of Indole Acetic Acid (IAA), Abscisic Acid (ABA), Ethylene, Salicylic Acid (SA) and Jasmonic Acid (JA) so that later it could be screened for some ornamental indoor plants that could be used as a phytoremediator agent. The ornamental plants used are Drimiopsis kirkii, Epipremnum pinnatum, Sanseviera trifasciata, Peperomia obtusifolia variegata and Dieffenbachia seguine. Exposure to plants with cigarette smoke containing formaldehyde as much as 0.1 ppm for 5.5 months then the content of the PGR was observed. The results showed that of the five ornamental plants used, there were two expression patterns of PGR. In D. kirkii and P. obtusiifolia-variegata there has been an increase in IAA, while 3 other species have decreased. Exposure to cigarette smoke decreases ABA in all five species while Ethylene increases. The most interesting discussed in this research is the increase in IAA in D. kirkii was not followed by changes in the expression of SA and JA.

Abstract
Garbage from dry leaves in a housing complex is often piled up and fills up green spaces. To utilize the waste of dried leaves, an organic fertilizer can be made using this dried leaves. The objection of this research is to utilize organic waste by adding bio-activator, which is called effective microorganisms (EM4). The composition for independent variables is dried leaves with EM4 20mL/5 kg dried leaves. In this research, it was used the aerobic method and stacked on a wooden box with dimension of 6 m x 6 m. Under aerobic condition, the results showed that the best content levels of C, N, P, K were C = 51.76%, N = 3.96%, P = 19.79% and K = 0.49%. For the anaerobic condition showed levels of C = 73.44%, N = 3.49%, P = 10.38% and K = 0.57%. The organic fertilizer applied to the growth of many plants in the area of Keputih Dian Regency, Surabaya.

Abstract
Phosphate-Solubilizing Bacteria (PSB) are microorganisms that play an important role in the biochemical cycle of the soil. This paper aims to discuss the role of these bacteria in comprehensive coverage with literature study methods. This bacterium has another role besides solubilizing phosphate in the soil such as suppressing the growth of pathogens for plants, fixing nitrogen to mobilizing heavy metals so that it is not harmful to living things. The mechanism of bacteria in carrying out this role is by secreting organic acids. The group of phosphate solubilizing bacteria varies, such as the Pseudomonas, Burkholderia to Leclercia groups
