Abstract

The objective of this research was to know the chemical stability of the etil para-metoksi sinamat (EPMS) formulated in sunscreen cream of oil in water base. The EPMS was isolated from Kaempferia galanga L. tuber pulvis with maceration-percolation method using ethanol 96%. The chemical stability of the EPMS formulated in sunscreen cream of the oil in water base was investigated by keeping the cream at room temperature. At appropriate interval the concentration of EPMS in cream was measured. The results showed that the EPMS formulated in sunscreen cream of oil in water base was unstable at room temperature for 70 days. The concentration of EPMS in cream significantly decreased after 70 days (p = 0,01) during keeping at room temperature with the coefficient degradation value (k)= 4.4.10-3/day.

Abstract

Estrogenic effects of handeuleum leaf {Graptophyllum pictum (L.)Griff)} were showed by uterus histology examinations of ovariectomy female mice. Female mice aged 3 months, were treated by gavage with handeuleum leaf extracts, ethinyl estradiol, aqua dest, and olive oil. The results showed that the treatment of handeuleum leaf extracts (with concentration 0.5 mg/0.05 ml olive oil) could increase uterus diameter, mucous layer thickness, lumen epithelial cell height, and glandular epithelial cell height if it was compared with aquadest treatments. Compared with ethinyl estradiol as standard estrogen, handeuleum leaf extracts have lower effects than ethinyl estradiol.

Abstract

Water pollution lately is often becomes an important topic due to its correlation with health. Heavy metals that accumulated in human body mostly come from food. One kind of food that used to be contaminated by heavy metals is fish. Therefore it is interesting to study the heavy metals content in fish, whether it comes from industrial contaminated water. Study on the content of heavy metals Cr, Cu, Pb and Zn in ponds near and far from industrial areas has been conducted. The chosen areas were one from Sidoarjo area and one from Babat area, both are located in East Java. Samples were the meat of fish called tilapia (from Sidoarjo area), and milkfish and goldfish (from Babat area), also the water and mud from the ponds. Analytical method was wet destruction. Measurement of heavy metals content was done by Inductively Coupled Plasma Spectrometer (ICPS). In Babat area’s pond water was not found neither Cr, Cu, Pb nor Zn, while Zn was detected in Sidoarjo area’s, however, it was under the limit of detection. The mud of both ponds contained Cr, Cu, Pb and Zn. The goldfish contained only Cu and Zn, whereas the tilapia and milkfish contained Cu, Pb and Zn, however the metals content were not exceeded the maximum limit stated in the PPOM regulation No. 03725/B/SK/VII/89.

Abstract

Prolonged and repetitive skin exposure to the sunlight can cause several disadvantageous effects. The harmful UV radiation of sunlight includes UV-A, which is implicated in tanning, photo aging and UV-B, which is especially responsible for erythema. For protecting the skin against UV light, the pharmaceutical sunscreen products with several active ingredients include natural product-essential oils are used. In this experiment we have investigated the effect of several essential oils as protection of the skin against UV light. The essential oil that used in this experiment were Lavender oil, Kenanga oil, Nilam oil, Geranium oil, Rosemary oil, Neroli oil, and Rose Moroccan oil. The sunscreen effectiveness determination was performed in vitro by determine their percentage of erythema transmission and percentage of pigmentation transmission employed spectrophotometer at wavelength 292.5–372.5 nm. The results showed only lavender oil was effective as sunscreen with the percentage of erythema transmission and percentage of pigmentation transmission was 9.94% and 80.15%, respectively. It was categories as suntan.

Abstract

The quality of nilam (Pogostemon cablin Benth) oil depend on it patchouli alcohol value. At there time nilam farmers just has produced nilam oil with patchouli alcohol value about 26–28%. To increase this value, fractional vacuum distillation had been done in this study. Nilam oil has been isolated from drying leaf of nilam plant. Patchouli alcohol in this oil was analyzed by gas chromatography, next the oil was distillated by fractional vacuum and the patchouli alcohol was determined from each fraction. This study showed that fractional vacuum distillation of nilam oil gives a higher patchouli alcohol value. The increasing was 23.3387%; from 35.022% at nilam oil before fractination vacuum distillation to 58.3515% at the third fraction from fractional vacuum distillation. In fact, the fourth fraction had the highest patchouli alcohol, but it had dark colour so isn’t fill the standard quality.

Abstract

The objective of the research was to find out the effect of repeating cycle of feed deprivation followed by fixed refeeding on the food consumption and feed efficiency of grouper Cromileptes altivelis. The experimental fish weight was 10.86 ± 1.42 gram. The treatments included: (P1) group received repeating cycles of 1 day food deprivation followed by 2 days refeeding in 14 cycles; (P2) group received repeating cycle of 1 day food deprivation followed by 3 days refeeding in 10 cycles; (P3) group received repeating cycle of 1 day food deprivation followed by alternating 2 and 3 days refeeding in 12 cycles and; (K) group fed daily as control. Each treatment was assigned to 3 aquaria containing 150 l recirculated sea water according to completely randomized design. Twenty individuals were stocked in each aquaria. The fishes were fed with floating pellet twice a day at 09.00 and 15.00 to satiation for four weeks. Water quality was monitored. The results showed that repeating cycle of food deprivation followed by fixed refeeding affected food consumption and feed efficiency in grouper Cromileptes altivelis. Food consumption of fishes from treatment groups showed lower food consumption than control, but they showed higher daily food consumption and feed efficiency. This phenomenon could be applied in practical feeding management for application to mariculture.

Abstract

The easiest, cheapest, simpliest and efficient polyploidization method was heat shock treatment. Each fish species has different tolerance either initial time, temperature or duration of heat shock. The aim of this study were to show and determine the heat shock effects on differentiation of hatching rate, abnormality, survival rate, and successful polyploidization of common carp. The method that used in this study was experiment. Treatment that used was heat shock 40° C during 1.5 minutes of common carp eggs to 3 and 29 minutes after fertilization. Ten replicates were carried out for each treatment. Parameters test were hatching rate, abnormality, survival rate and polyploidy induction by counting of nucleolus number. Data analysis that used was descriptive. The result of this study indicated that heat shock treatment influenced on hatching rate, abnormality, survival rate and polyploidy induction of the common carp polyploidization. Hatching rate of common carp, triploidy and tetraploidy were 22.63 ± 8.36% and 11.10 ± 8.60%, abnormality 13.81 ± 4.67% and 24.86 ± 8.37%, survival rate 52.64 ± 8.46% and 55.04 ± 8.15% and polyploidy induction 70 ± 7.07% and 60 ± 7.07%, respectively.

Abstract

Penyebab kematian lou han Cichlasoma synspilum adalah Aeromonas hydrophila dan Escherichia coli, dengan ciri adanya pendarahan dan luka pada sirip dada. E. coli kemungkinan besar tidak menyebabkan kematian ikan sebab sampai sekarang belum pernah ada laporan bahwa bakteri tersebut menyebabkan sakit pada ikan di mana pun. Gejala klinis utama yang terlihat dari luar adalah pendarahan di sirip dada dan menimbulkan luka yang cukup dalam. Cairan ascites menyebabkan membengkaknya perut, pembengkakan liver, dan kosongnya usus dari ikan yang sakit. Gambaran histopatologi menunjukkan nekrosis dan adanya vacuole pada hepatocyte. Sedangkan pada usus adalah rusaknya mucosal ephitelium, lamina propia stratum compactum, stratum granulosum dan muscularis. Ginjal mengalami kerusakan berat, hampir semua organela ginjal berantakan. Ikan ini dipelihara di aquarium sehingga menurunnya kualitas air atau kontaminasi lewat pakan dan penanganan yang buruk diduga sebagai portal of entry dari penyakit.

Abstract

Trichoderma harzianum is a well-known mycoparasitic fungus that has been used as biocontrol agent of many phytopathogenic fungi. One of the effort to improve the ability of wild strain of T. harzianum in its antagonistic activity is by exposed them in gamma ray iradiation. In this experiment wild strain of T. harzianum iradiated gamma ray of Cobalt-60 (0.25 kGy, 0.5 kGy, 0.75 kGy, and 1 kGy), then assess the effect of the iradiation on its growth, the antagonistic activity and chitinase activity toward Fusarium oxysporum. Results showed that iradiation of gamma ray 0.25–1 kGy has no effect on the growth of T. harzianum and its antagonistic activity, but it significantly influence the chitinase activity. Probably the fungi have repaired the damage of DNA caused by iradiation, so that the growth and even the enzymatic function has no longer affected.
