Abstract

Mangrove forest is a natural resource typical of tropical coasts, which has multiple benefits with a very broad impact when viewed from social, economic and ecological aspects. Management of natural resources must be very prudent because it takes a long time to be able to recover when damage / extinction has occurred. The purpose of this study was to determine the composition of mangrove species, the structure of mangrove forest vegetation (species density, relative density of species, frequency of species, relative frequency of species, species cover, relative cover of species and important values) and to determine the level of damage. Extraction of mangrove vegetation using the "spot check" method. The transects are drawn perpendicular to the coastline along the mangrove vegetation. The composition of mangrove species were 7 species, namely Rhizophora apiculata, R. stylosa, Bruguirea gymnorrhiza, Ceriops tagal, Sonneratia alba, Xylocarpus granatum and Aegiceras floridum. In the vegetation structure, the highest density and relative density were found in Rhizophora stylosa and the lowest was Xylocarpus granatum. The highest species and relative frequencies were Rhizophora stylosa, R. apiculata and the lowest were Bruguiera gymnorrhiza. The highest type and closure were Sonneratia alba and the lowest was Ceriops tagal. Meanwhile, the highest importance was in Sonneratia alba and the lowest was Xylocarpus granatum. Overall, the density value of mangrove species on Manomadehe Island is 2796 trees / ha so that the condition of the mangrove forests on Manomadehe Island is still in the good category (very dense).

Abstract

Cantang grouper is one of the leading NTB commodities that have high economic value. Cantang grouper (Epinephelus fuscoguttatus) has a wide distribution, one of which is in Penyambuan Village, North Lombok Regency. The disease that often attacks grouper fish is VNN (Viral Nervous Necrosis). One of the methods that can be used to detect VNN is the histopathological method. The purpose of this study was to determine the suspected cases and levels of infection with the VNN (Viral Nervous Necrosis) virus in grouper fish (Epinephelus fuscoguttatus) cultivated in Penyambuan Hamlet, Tanjung District, North Lombok Regency by using the histopathological method. The research method used is descriptive by explaining the results obtained from the histopathological test of 3 samples taken by looking at the presence or absence of necrosis in the eye and brain organs of the test sample. The results of observations using a microscope on the test sample after the histopathological process showed that the second sample (S2) of cantang grouper from the KJA in Pemambuan was suspected to be positive for VNN infection, as seen from the presence of necrosis in the form of vacuoles in the brain and eye organs in the level of chronic infection. From the results of this study, it is suggested that further research be carried out in the form of confirmation of the results using a more accurate method, namely real-time PCR. This study can serve as a detection guide for samples of suspected VNN.

Abstract

Patient compliance refers to the suitability of behavior against treatment recommendations include timing, dose and frequency of treatment. Compliance to tuberculosis treatment was actually very complex and dynamic with various factors that interacted each other, and therefore it will influence on patient’s behavior decision. Patient who has a good compliance will increase success to his recovery. This study was carried out to determine the correlation between tuberculosis patient behavior which consists of the domain of knowledge, attitudes and practices with compliance to taking anti-tuberculosis drugs at the Puskesmas Cakranegara commencing on July to November 2020. This research was an observational analytic study using a cross sectional method. Population sample was patients who diagnosed with pulmonary tuberculosis which undergoing category 1 treatment at Puskesmas Cakranegara. The data used in the study was primary data established from interviewing patients using a questionnaire on selected Pulmonary TB patients including respondents who eligible as the inclusion and exclusion criteria. The number of samples in this study were 30 infected-people. The data obtained were analyzed using the Spearman correlation test.  The correlation test of the study showed that there was no significant correlation between variable of knowledge and medication compliance (p = 0.079, r = 0.325).  However, the attitude variables had a significant correlation with medication compliance (p = 0.000, r = 0.715).  Similarly, the practices variable has a significant correlation to the medication compliance (p = 0.000, r = 0.656). This study found that there was no significant correlation between knowledge and compliance taking anti-tuberculosis drugs. However, it was found that there was a significant correlation between attitudes and practices with compliance to taking anti-tuberculosis drugs.

Abstract

Small and medium industries are experiencing growth every year. The home industry of tofu production is one of the small and medium industries that continues to grow and develop. However, there is a problem if the tofu production waste is disposed of directly into the waters, it will cause pollution due to the deposition of organic material. The research objective was to analyze the subsurface flow-wetlands with plants namely water hyacinth, apu wood and lemna minor to reducing TSS levels and stabilizing pH. This research an experimental with treatments including SSF-Wetlands without water plants (A1), SSF-Wetlands with water hyacinth (A2), SSF-Wetlands with apu wood (A3), SSF-Wetlands with lemna minor (A4) and SSF-Wetlands with water hyacinth, and apu wood (A5). The stages of this research are the sampling stage, the SSF-Wetlands manufacturing stage, the waste treatment stage and the pH and TSS testing stages. Data were analyzed using one-way ANOVA (SPSS 20). The results showed that the liquid waste of tofu in the initial sample was acidic, namely 3.94 and the TSS level was 858 mg / L. The pH condition of the waste after processing by the quality standard.  The highest increase in pH and decrease in TSS levels in the tofu liquid waste treatment was the SSF-Wetland processing with water hyacinth plants (A2). This shows that water hyacinth plants have a greater role in neutralizing pH and can absorb the most suspended matter compared to apu wood and lemna minor plants.

Abstract

Cherry leaf is a natural ingredient that can be used as a feed additive because it contains flavonoids, tannins, saponins, triterpene and polyphenols which are antioxidants. This study aims to determine the effect of giving cherry leaf extract on the growth of vaname shrimp. A total of 20 vannamei shrimp in the PL-20 phase measuring ± 0.1g / head are kept in a 40 liter container. The method used in this study was an experimental method using a completely randomized design (CRD) with 4 treatments and 3 replications, namely P1: feeding without cherry leaf extract (control), P2: feeding with the addition of 1% cherry leaf extract, P3: feeding with the addition of 2% cherry leaf extract and P4: feeding with the addition of 3% cherry leaf extract. The data obtained were analyzed by ANNOVA test with a confidence level of 95% and Duncan's continued test. The results of this study indicate that the addition of cherry leaf extract can affect the growth of vaname shrimp, but has no effect on the FCR value and survival rate. The addition of cherry leaf extract to a concentration of 3% can increase the growth of absolute weight and length and the specific growth rate of vaname shrimp which is better than the treatment without the addition of cherry leaf extract. Therefore cherry leaf extract has the potential to be used as a feed additive.

Abstract

Habitat is a place for living things to grow and develop. Differences in physical characteristics of habitats within an area can affect the morphometry of an organism. This study aims to provide information related to the morphometric variation of the carpenter bees Xylocopa confusa Latreille and Xylocopa latipes Drury in different habitats in Central Sulawesi. The research was conducted in four types of habitat, namely primary forest, secondary forest, rural areas, and urban areas in January 2019. The collection of carpenter bees useds a sweep net by swinging it around the sampling location. The carpenter bees obtained were then killed in a killing jar for five minutes. The carpenter bees samples were put into a sample bottle based on the type of habitat. Furthermore, the pinning process was carried out using insect needles. The results showed that the physical characteristics of the different habitats could affect the morphometric variations of the carpenter bees Xylocopa confusa and Xylocopa latipes. The size of the body morphometry of carpenter bees is larger in primary forest habitats, while the smallest size of bees is found in urban areas. This research is useful as preliminary data before carrying out the cultivation and conservation process of wood bees considering that their role in nature is very important.

Abstract

Green betel leaf (Piper betle L.) contains secondary metabolites, namely alkaloids, flavonoids, steroids, terpenoids, saponins, tannins. Green betel leaf (Piper betle L.) is widely used for wound healing, especially in rural Indonesians. This study aims to determine the effect of green betel leaves extract (Piper betle L.) on wound healing in mice (Mus musculus L.). The samples were determined using a randomized block design (RBD) using mice (Mus musculus L.) which consisted of three treatment groups using a concentration of 20%, 30%, 40% and one control group. The Measure of the average diameter of the wound was using a ruler on each side of the diameter. The data measurement for the average diameter of wound restriction was analyzed by using the one way. The one way Anova test showed that the sig or p-value is 0.000 <0.05 (at the alpha level of 5%) so that Ho is rejected which indicates that there is an effect of giving green betel leaf extract (Piper betel L.) on wound healing in mice (Mus musculus L.). Based on the results of the LSD or LSD test, it shows that it is not significant / the same because the sig value is 0.074> 0.05, which means that no change occurs in mice when given 30% or 40% extract. Green betel leaf extract (Piper betle L.) has an effect on wound healing in mice (Mus musculus L.).

Abstract

Mosquito-borne diseases include tropical diseases such as malaria, filariasis, dengue fever, chikungunya, yellow fever and cerebral fever are still major health problems in Indonesia and on a global scale. Various methods have been used to overcome this, including controlling vector mosquitoes using the entomopathogenic microbial Lysinibacillus sphaericus. This study aims to identify bacterial isolates collected based on the 16S rRNA gene and to carry out the pathogenicity test of the bacterial isolates collected on Cx. quinquefasciatus larvae. Bacterial isolates used in this study were collected from root soil, bird droppings and guano. The identification of the type of bacteria was carried out based on the 16S rRNA gene fragment. Based on the results of the 16S RNA sequence analysis of isolates 229C, 6B4, 6.2 and 4D21, it was found that the four isolates were included in the L. sphaericus species with similarity scores ranging from 97% to 100%. The pathogenicity of bacteria was measured based on the mortality of Cx. quinquefasciatus larvae to know whether it has pathogenicity equal to or higher than strain 1593. The pathogenicity test results of 6 isolates 15.4, 229C, 1593, 6B4, 6.2 and 4D21 showed that isolate 15.4 has the highest larval mortality rate, so it is potentially used as a biological agent to control disease vector mosquitoes.
