Abstract

The egg-laying chicken has a coarse texture with large fiber bonds, so it is classified as tough meat. The level of toughness of the meat can be improved by applying the compression technology using enzyme extracts such as papaya extract. The purpose of this study was to determine the effect of the level of use of papaya extract (Carica papaya) on the tenderness and structure of the rejected laying hens. The research material used was 4.500 g of egg rejected chicken meat and half-cooked papaya fruit extract. Meat tenderness testing is done by the Shear Press method, while observing the meat structure is done by microtechnical methods using binocular and digital microscopes. Data analysis of meat tenderness analysis with analysis of variance based on the Completely Randomized Design (CRD) of Unidirectional pattern with 4 treatments (P1= control, P2= 15%, P3= 30% dan P4= 45%) with 3 replications, while the meat structure was analyzed by calculating the average size of connective tissue and meat fibers in the form of millimicron units (µm). The results showed that soaking papaya meat extract with different concentrations significantly affected (P<0.05) on the tenderness of laying hens. The tenderness of meat indicated by the value of meat breaking was ranges from 0.90 kg/cm2-1.36 kg/cm2. Observation of meat structure shows that the higher the concentration of papaya extract used to soak the meat, the connective tissue narrows and the muscle fibers widen.

Abstract

Red rice cv. Barak Cenana is a local Indonesian rice which is widely planted in Tabanan Regency, Bali. Barak Cenana red rice has potential as a functional food because it contains a lot of nutrients. However, this rice has an unfavorable character, such as long harvest time so that it can only be harvested once a year, and tall stature that causes plants to lodge easily, reducing its productivity. This study aims to determine the effect of gamma rays on growth and development as well as changes in character to obtain mutants plants that have better character. In this research, Barak Cenana seeds were irradiated using gamma rays with irradiation doses of 100 gy, 200 gy, 400 gy, and 800 gy. Furthermore, radiated seeds were planted in the greenhouse and characterized during the vegetative and generative phases including shoot length, harvest time, chlorophyll content, the number of productive tillers, the number of grain contents, the weight of 1,000 seeds, and the polymorphism profile using Random Amplified Polymorphic DNA Analysis (RAPD). The results of this study indicate that all radiation doses produce plants with random characters. Mutations using gamma rays at doses of 100 gy and 400 gy produced plants with better phenotypic characters than wild-type that is shorter plants, shorter harvest times, and more grain content. In addition, the results of the RAPD analysis confirm that there are genetic changes in irradiated rice. This mutants has the potential to reproduce germplasm and to obtain the next generation of mutants that have higher productivity and shorter plant heights.

Abstract

Dayak Desa is a sub-tribe of a large group of Dayak tribes in West Kalimantan. Within the tribal community, it is estimated that there are still several traditional healers (battra) practicing traditional medicine. This study aims to identify the existence of traditional healers from the Dayak Desa tribe in the villages of Kebong and Merpak, analyze the species of medicinal plants used by traditional healers of Dayak Desa and analyze the similarities/ differences in knowledge of medicinal plants possessed by traditional healers and the general communities in Kelam Permai Sub-district. This study used an in-depth interview method to traditional healers from the Dayak Desa tribe with questionnaire aids, which contains questions related to the species of medicinal plants used in their practice. Data analysis was in the form of many species of medicinal plants used by traditional healers, plant families, habitus and parts of plants used, methods of processing and use, location, and sources of medicinal plants taken. The results showed that in Kebong and Merpak villages, there were still four traditional healers practicing traditional medication and using 59 species of medicinal plants. There are 39 species of plants used by traditional healers and also used by the communities, while 20 species others only used by traditional healers. The highest use is found in the family of Poaceae (5 species), herb habitus (37%), processing method by boiling (30%), and administration method by drinking (29%), and paste (29%), the form of single-use and mixture is quite balanced (49 and 48%). The primary source of obtaining medicinal raw materials comes from the yard (57%), and plant sources come from wild growing (59%). The knowledge of medicinal plants possessed by traditional healers should be continued documented; thus, the diversity of medicinal plants can be preserved for the next generation.

Abstract

Cheese is a processed product with a basic ingredient in the form of milk which is produced by separating solid substances in milk through a coagulation process. Soft cheese is cheese with a moisture content of 45-80%. Research aims to know the benefits of biduri juice in the manufacture of buffalo milk soft cheese. In an effort to determine the benefits of the biduri juice an experimental method was carried out using a Randomized Block Design (RBD).The study consisted of two groups, namely K1 which was made of cheese using 0.02 ml / 2 liter of rennet milk, while K2 was made of cheese using 0.6 cc/2 liter of biduri sap milk. The cheese produced on K1 and K2 was stored for 0 days, 12 days and 24 days as treatment. The results of the study which consisted of protein, fat and water levels were analyzed using analysis of variance based on a Randomized Block Design (RBD) using the SPSS version 16 program and continued with the Duncant test with a confidence level of 5%. The results showed that the use of biduri juice 0.6 cc/2 liters of milk in cheese making produced cheese with protein content ranging from 22.74-23.85% higher than the use of rennet at 21.99-23.65%. Fat content of cheese with biduri juice coagulation resulted in fat content ranging from 0.59-0.84% lower than using rennet ranging from 0.8-1.04%. The water content of soft cheese coagulated with biduri juice and rennet is still in the normal range of water content set by the United States Department of Agriculture (USDA), which is not more than 80%. Based on the results of the study, it can be concluded that the use of biduri juice at the level of 0.6 cc / 2 liters of fresh buffalo milk in making soft cheese with a storage time of 0 days, 12 days and 24 days, it can produce protein and fat content of soft cheese that meets SNI with water content of cheese according to USDA standards, namely not exceeding 80%.

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

One local alternative that is available is the use of natural coagulants from the Moringa oleifera L. seed starch plant. Moringa seeds have antimicrobial properties that can reduce substances that should not be present in clean water so that they can purify water for clean water needs. However, the distinctive aroma of moringa is still felt, so it needs to be filtered using coconut shell charcoal and fibers . Research objectives: to determine the characteristics of domestic wastewater (pH, TSS, BOD, oil and fat) and after adding Moringa seeds as a coagulant and coconut shell charcoal and fibers as a filter media . This research was conducted in Nunleu Village-Kupang City and the NTT Provincial Health Laboratory. The method used is experiment and laboratory analysis . Phase I samples were analyzed in the laboratory to determine the characteristics of the initial water. Phase II of water purification experiments with treatment A: coagulant 150 mg / l + 10 cm thick activated charcoal + 10 cm palm thickness. Treatment B: coagulant 150 mg / l + fiber thickness 10 cm + activated charcoal thickness 10 cm. The results showed that the treatments (A and B) could reduce pH, BOD, TSS as well as oil and fat. The pH parameter has decreased tends to be acidic. TSS increased by 58.8% in Treatment (A) , but in treatment (B) there was a decrease of 15%, the TSS content still exceeds the quality standard for domestic waste set by the 2016 Ministerial Regulation, 30 mg/L.The BOD content decreased by 45.2% in treatment A while in treatment B there was a decrease of 58.3% . Furthermore, the oil and fat content was quite low, namely in treatment A there was a decrease of 45.2% while in treatment B there was a decrease of 58.3%.

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

Ridan (Nephelium maingayi) is one of Nephelium (Sapindaceae) member distributed in Riau Province. This underutilized edible plant is commonly found as wild species, and poses three different fruit morphologies (oval, asymmetric and rounded shaped fruit). The phytochemical contents of these fruit species had not been reported. This study aimed to identify the phytochemical contents of fruit parts (peel, aril and seed) of three different fruit shapes of N. maingayi (oval, asymmetric and rounded shaped fruit) from Riau Province. A total of six secondary metabolite groups were tested (alkaloid, terpenoid, steroid, flavonoid, saponin dan tannin), using qualitative analysis based on the presence of precipitation (alkaloid), the change of mixture color (steroid, terpenoid, flavonoid and tannin) and soapy foaming substance for saponin. The result showed that peels of Ridan (N. maingayi) gave the highest phytochemical contents (alkaloid, terpenoid, flavonoid, saponin and tannin.). Terpenoid and saponin were found in peel, aril and seed of three different fruit shapes. This study concluded that the phytochemical contents of three fruit shapes of Ridan (N. maingayi) varies among the different shapes of fruit. This result of this study provide the first information of bioactive profile of N. maingayi form Riau Province.
