Sea cucumbers are a marine source with biological activities that have been used in food as well as medicine in many Asian countries. Actinopyga mauritiana is one of the sea cucumber species with limited research about its bioactive activities. In this study, the wound healing activity of A. mauritiana extract in the form of cream, gel, and serum formulations in mice was investigated. The histopathology test was performed to evaluate the fibroblast and collagen dense levels in wound healing. Phytochemical screening has been carried out by the qualitative test of alkaloids, flavonoids, glycosides, steroids, and saponins compounds. The A. mauritiana ethanol extract (SCAE) was added into cream, gel and serum formulations with various concentrations (3, 6, and 9%) and applied to the wounded area of mice. The wound healing activities and histopathology results indicated that serum 9%-SCAE performed the highest decrease of wound length 0.55 ± 0.32 compared to other groups with a density level of fibroblast and collagen are 10.00 ± 1.00 and 10.67 ± 0.00, respectively. To the best of our knowledge, this is the first report on the wound healing activity of A.Mauritiana, which demonstrated promising therapeutic agents for wound healing and cosmetics applications in the future.

It has been conducted a geo-electrical resistivity survey at geothermal area of Ie Jue, Aceh Besar. The survey aims to measure resistivity value in the area. It is expected that the values of resistivity will image the subsurface structure in the area. In addition geological features in the area are shown after we process it. The data acquisition in this study was acquired using a SuperSting R8/IP resistivitymeter and its data processing using EarthImager 2D software to get the image of resistivity pseudosection. The two lines of measurement crossed the surface geothermal manifestation. Each line has 330 m in length, and 56 electrodes with electrode space of 6 m. The result of resistivity pseudosection model interpreted based on geological condition and observation in the area. Resistivity pseudosection model shows the study is water-saturated (64.0 Ωm) to a depth of ±65 m and a highly conductive zone (0.6-3.5 Ωm) with a thickness of 30-50 m. This conductive layers below the embodied surface at a distance of 158-160 m on the IJ-Y1 line and at a range of 130-185 m on the IJ-Y2 line. This conductive zone is indicated as a weak zone where geothermal fluids are transported to the surface.Keywords: Geothermal, Ie Jue, geo-electrical resistivity survey, resistivityREFERENCES Bennet, J.D., Bridge, D.McC., Cameron, N.., Djunuddin, A., Ghazali, S.A., Jeffrey, D.H., Kartawa, W., Rock, M.N.S., Thomson, S.J., Whandoyo, R., 1981.

Cissus quadrangularis Salisb is a medicinal plant which has been used traditionally to cure bone fracture by Acehnese. This study was carried out to investigate the administration effects of Cissus quadrangularis Salisb extract (CQSE) on the histology of lumbar bone in ovarectomized rats. There were 16 female rats (Rattus norvegicus) as samples and were then divided into 4 groups of treatment, with 4 replications each. K0 consisted of ovarectomized rats without CQSE supplementation, whereas K1, K2 and K3 consisted of ovarectomized rats administrated with 300, 500 and 700 mg/kg body weight CQSE for 60 days, respectively. On the day 61st, all rats were euthanized with chloroform and their fourth lumbal bones were collected for histological preparation. Parameters observed were densities of active osteoblast, passive osteoblast and osteoclast. The results of this study showed that density of active osteoblast of rats in K3 (27.25 ± 2.75) was significantly higher (P0.01) than rats in K0 (1.75 ± 1.25), K1(4.00 ± 1.41), and K2 (8.50 ± 7.40), respectively. There was no significant difference (P0,05) of passive osteoblast density among rats in K0 (16.50 ± 6.13), K1 (41.00 ± 6.48), K2 (44.50 ± 16.34), and K3 (39.00 ± 15.23). Osteoclast density of rats in K0 (85.25 ± 25.91) was significantly higher (P0,05) than that of rats in K1 (52.50 ± 16.66), K2 (51.00 ± 7.16), and K3 (50.75 ± 9.20). In conclusion, consecutive administration of 700 mg/kg body weight of CQSE extract for 60 days might increase active osteoblast density in ovarectomized rats.

Factors that cause fluctuations in chili production are nutrient content and attack by plant disturbing organisms (PDO). To overcome pest attacks can be done by planting refugia which serves as an alternative that will bring in natural enemies. In addition, the application of cow dung and mycorrhizal compost as biological agents will be able to maintain soil quality and plant growth. This study aims to determine the effect of cow waste compost and arbuscular mycorrhizal fungi (AMF) on the growth and production of red chili plants intercropped with refugia plants. The method was a factorial randomized block design consisting of 2 factors, namely: cow waste compost and AMF. Cow waste compost consists of 5 levels, namely: K0 = without giving cow waste compost, K1 = cow waste compost at a dose of 5 tons/ha-1, K2 = cow waste compost at a dose of 10 tons/ha-1, K3 = cow waste compost at a dose 15 tons/ha-1, K4= cow waste compost dose of 20 tons/ha-1. Meanwhile, arbuscular mycorrhizal fungi consisted of 4 levels, namely: M0= without AMF, M1= AMF 50 kg/ha-1, M2= AMF 100 kg/ha-1, M3= AMF 150 kg/ha-1. The results showed that AMF had a most significant effect on the number of fruits per plant, production per plant, and production per plot, but not significantly different on plant height, some branches, and flowering age of Laris variety red chili. AMF treatment with 150 kg/ha (M3) dose had the highest average value for all observed parameters.

Exploitation of extremophiles as novel bioactive compounds sources has been increasing. The aim of this study was to evaluate the activity and the class of antibiotic produced by a thermo-halophilic isolate PLS 76, as well as to identify the genotype of the isolate. The activity was determined by a disc diffusion method, while the antibiotic class was determined qualitatively by chemical reactions using ninhydrin, iodine vapour and potassium iodine. The genotype was determined by sequencing the 16S rRNA gene fragment and the phylogenetic tree from the sequence data. The results showed that PLS 76 was a Gram-negative bacterium and able to produce polypeptide antibiotic, which showed a slight activity on E. coli and S. aureus. Sequence alignment of the 16S rRNA gene fragment showed that PLS 76 was most related to Geobacillus kaustophilus. These results may be used to utilise the isolated for further antibiotic study.

Mosquito coils contain active compounds such as chlorpyriphos, dichlorphos, and d-alletrhrin which may be hazardous to the health. As majority of pesticides are stable heat, they can be changed into stable vapor state by column. a gas chromatographic method of analysis was developed. Gas chromatography for organophosphate compounds, namely chlorpyriphos and dichlorphos, with a OV-17 packed column, and a flame photometry detector equipped by filter for phosphor, which detecs phosphor containing compounds exclusively, avoiding any interference of other non phosphor compounds present in the sample matrix. Gas chromatography for a pyrethoid compound, d-allethrin, utilizes a HP-1 capilarry column with a flame ionization detector, and detect, any ionizable compound. The research was initiated by adjustment of the condition of gas chromatography system to obtain an appropiate separation of compounds a good shape of chromatogram and a tolerable retention time. With a flow rate of nitrogen 55 ml/min, column temperatures of 210oC, a detector and injector temperature of 230oC, the method gave a retention times chlorpyriphos of 6,47 minute and that of dichlorphos of 0,73 minute . The difference in retention time of chlorpyriphos and that of dichlorphos was caused by the difference in molecular weight of both compounds, thin dichlorphos with a smaller molecular weight (220, 98) was eluted faster than chlorpyriphos (350,6). For d-allethrin whit a flow rate of nitrogen gas of 40 ml/min, a column temperature of 180oC, a detector and injector temperature of 210oC, a retention time of d-allethrin of 3,28 minutes was obtained. The mosquito coils tested did not contain any chlorpyriphos nor dichlorphos, and some contained d-allethrin. The d-allethrin content obtained in one of the sample was beyond the tolerated limit.

Rhizobacteria play a positive role as biocontrol agents as well as Plant Growth Promoting Rhizobacteria (PGPR) agents. The research objective was to obtain indigenous rhizobacteria isolates on cocoa plants that have the potential to inhibit the attack of P. palmivora fungal pathogens, and act as PGPR in vitro and in vivo. The results of the study concluded that isolates TRI 7/1, TRI 8/8, GM 7/9 and GM 7/10 had the highest ability to inhibit the growth of pathogen. The lowest disease severity (20%) was obtained in the seedlings treated using isolates TRI 7/1 and TRI 8/8. Rhizobacterial isolates GM 3/6, GM 5/6, GM 7/9 and GM 8/8 produce high amounts of IAA. Rhizobacteria isolates GM 5/6, GM 7/9 and GM 8/8 has very high peroxidase enzyme activity. High production of HCN compounds was obtained in rhizobacteria isolates TRI 3/3, TRI 4/10 and TRI GM 8/11. All rhizobacterial isolates gave an increase in the value of maximum growth potential, germination and vigor values for growth strength compared with the control. The rizobacteria treatments using isolates TRI 7/1, TRI 8/8, GM 7/9 and GM 7/10 were able to increase plant height, stem diameter and number of leaves at 30, 40, 50, 60, and 70 DAP compared to control treatment.

Abstract. Determination of radon concentrations in dwelling in Aceh region by using a passive method has been conducted. In this research, area considered was divided into several sections called grid. Each grid represents an area of 60 km x 60 km in which, depend on public response, 6-10 passive radon monitors were installed. The number of passive radon monitors installed in Aceh is 200 units, and they can be taken back as many as 191 units or 95.50 %. The passive radon monitors have stayed in dwelling for 3-4 months and after period of the exposure, those radon monitors were taken back and brought to laboratory for further process, and then the track were read and the radon concentrations were calculated. Furthermore, data of radon concentration in dwelling and GPS location were put into MapInfo Software v.10.5 to create a map of radon concentration. The results of the analysis of the radon concentration in dwelling in Aceh demonstrate that the concentrations are in the range of 3.32 ± 0.23 Bq/m3 up to 68.30 ± 4.83 Bq/m3. This result was lower than the radon reference level determined by UNSCEAR, which was 300 Bq/m3. The data are useful in the regional extension and development plans, as well as the basis for health policy analysis due to the existence of radon in Indonesia. Furthermore, these data will become the contribution of Indonesia in the international world through UNSCEAR, IAEA and WHO. The data obtained can be used as partial data in creating a map of radon concentration in residents’ houses in Aceh, as a part of the map of radon concentration in Indonesia.

Tourism is one of the primary sectors that is expected to increase the regional government income. Therefore there is a need to observe the factors that affect the successfulness of tourism factors and products offered. Tourism products can be tourist destinations, where the characteristics of that particular destination can affect the decisions made by the tourist to return the place again. The characteristics of tourism in Aceh can be analyzed by using biplot analysis. Meanwhile, the effects of tourism characteristics on the number of tourists in Aceh from the year 2008 until 2013 is analyzed using panel data regression analysis that is approached by Fixed Effext Model (FEM). Based on the biplot graph, the cities that are superior in their number of all tourism products are Sabang and Banda Aceh. Cities other than these two cities tend to have a lower number of their tourism products. The biplot graph can explain the relationship between the variables of tourism products by 83.8%. Based on the model of fixed effect panel data, Aceh tourism products that affect the number of tourists in Aceh is the number of accommodations, restaurants, and tourist attractions. Fixed effect model explain correlation between the variables of tourism products to the number of tourists in Aceh by 78.8%.

Tuberculosis (TB) is an infectious disease which is one of the biggest health problems in the world, including Indonesia. The government, through the National Tuberculosis Control program, has made various efforts to control tuberculosis. However, this problem was exacerbated by the dramatic increase in the incidence of tuberculosis. This study aimed to determine the Cox proportional hazard regression model and the factors that affect the cure rate of TB patients. We used medical record data for inpatient TB patients for the period July-December 2017 at dr. Zainoel Abidin Hospital. The results showed that with α = 0.1, the factors that influenced the recovery of TB patients were the type of cough, the symptoms of bloody cough and symptoms of sweating at night. There were 33.93% of patients who did not work. This category included students, domestic helpers, and those who did not work until they suffered from tuberculosis and were treated at dr. Zainoel Abidin Hospital. The hazard ratio (failure ratio) showed that the tendency or cure rate for TB patients who did not experience cough symptoms was 70% greater than patients who experienced phlegm cough symptoms. The cure rate for TB patients who experienced coughing up blood symptoms was 53% greater than patients without these symptoms. The cure rate for TB patients who experienced symptoms of sweating at night was 54% greater than patients who did not sweat at night.
