Abstract

Pig farming is highly needed by the Bajawa community in their daily lives, so the Bajawa people see the necessity of pig farming not only for its social value but also because it is highly valuable due to its close connection with local customs and cultural rituals. The nutritional content of coffee fruit husks, which is almost similar to fine flour, and their availability, which has not yet been fully utilized, provide a significant opportunity to be used as feed material. The research aims to determine the extent of the effect of using coffee husk flour as a partial substitute for fine flour in feed on feed consumption, weight gain, and feed efficiency in grower phase pigs. This study uses a randomized block design with 4 types of feed (R0, R1, R2, R3) as treatments and 4 groups of pigs as repetitions, with each group consisting of 3 pigs. The results show that the use of coffee husk flour as a substitute for part of the fine flour in pig feed increases feed consumption, weight gain, and feed conversion in pigs during the grower phase. The best treatment is R3 (0% fine bran + 25% coffee husk flour). The results of the ANOVA test indicate that the provision of feed with coffee husk flour shows differences in feed consumption, weight gain, and feed conversion in pigs among each treatment with a significance value of 0.000. The Duncan post hoc test shows significant differences in feed consumption, weight gain, and feed conversion in pigs among each feed treatment.

Abstract

Skin is the outermost organ that functions to protect muscles, ligaments and internal organs that can cause premature aging. Aging can be characterized by dry, thin, inelastic skin, wrinkles, death of skin cells, uneven skin tone, hyperpigmentation and hypopigmentation. Thus we need a protection such as anti-aging cosmetics. Antioxidants are often added because they can reduce oxidative damage caused by increased Reactive Oxygen Species (ROS) due to ultraviolet light exposure. The research method used experimental laboratory. This sudy aims to determine ethanol extract of red spinach leaves that can be formulated in gel form as well as whether it can provide anti-aging effects on the skin. Organoleptic, homogeneity, viscosity, pH, and dispersion tests are all used to evaluate the form. Using a skin analyzer, the gel dosage form's efficacy is tested for irritation and anti-aging properties. The findings demonstrated that there were no coarse grains and that the ethanol extract of red spinach leaves at concentrations of 1%, 3%, and 5% did not alter color, odor, or shape. The form has a pH between 4.5 and 6.5, a viscosity between 2000 and 4000 mpa, and it did not irritate the skin. Water content and wrinkles showed a significant difference (p<.05) in the one-way ANOVA test findings, however pores, smoothness, and stains showed no significant difference p>.05. Formula that provides potential results for anti aging activity is a gel with an extract content of 5%.

Abstract

The ethnobotanical study of food crops is very important to be carried out because it can be a means of natural resource conservation, social and economic sustainability of local communities. The diversity of food crops on the island of Lombok reflects the interaction between humans and the environment as well as the cultural values contained in the practice of using food crops in daily life. The objectives of this study are to: a) identify food crops on the island of Lombok based on land characteristics, b) find out the distribution of food crops on the island of Lombok based on land characteristics, and c) find out how food crops are used by the community on the island of Lombok.  The sample was determined using the purposive sampling technique. Data were collected through semi-structured interviews and then plant specimens were collected accompanied by key informants in the field. Data analysis was carried out in a qualitative descriptive manner after being processed in Microsoft Excel using simple statistical techniques. Based on the results of the study, about 64 species of food crops were found. Land characteristics consist of wetlands, sandy lands, and dry lands. A total of 46 species of food crops were found in rice fields with wetland/clay characteristics. A total of 30 species of food crops were found on land with sandy characteristics and as many as 18 species of food crops were found on hilly land with dry land characteristics. The use of food crops by the community is ground as much as 10%, mashed as much as 12%, cooked as much as 60% and eaten raw as much as 40%. Based on the results of this study, it can be concluded that food crops are more commonly found on land with wetland or rice field characteristics and the use of food crops is most obtained by cooking.

Abstract

: Colorectal cancer (CRC) is the third most common cancer globally and the second leading cause of cancer-related mortality. It results from complex interactions between genetic, environmental, and lifestyle factors, with smoking and alcohol consumption being significant contributors. This study focuses on the correlation between smoking and alcohol consumption with CRC incidence in West Nusa Tenggara (NTB), a province in Indonesia known for its high smoking prevalence (32.79%) and alcohol consumption rate (1.6%). A literature review methodology was employed, systematically collecting data from PubMed, ScienceDirect, Cochrane Library, Google Scholar, and ProQuest using keywords such as "colorectal cancer," "risk factors," "smoking," "alcohol," "management," and "prevention." A total of 35 articles published between 2007 and 2024 were analyzed to provide a comprehensive synthesis of CRC risk factors, management approaches, and prevention strategies. The findings reveal a strong association between smoking and CRC risk, particularly among middle-aged males, while alcohol amplifies the risk synergistically. Despite limited alcohol prevalence, its impact remains substantial. The study emphasizes the importance of targeted public health interventions in NTB, integrating lifestyle modification campaigns and routine screenings to mitigate CRC risks and improve health outcomes in high-risk communities.

Abstract

Treatment of P. aeruginosa infection often involves antibiotics but these bacteria can develop resistance. An alternative strategy is developing drugs from natural ingredients such as gotu kola herb (Centella asiatica) which contains potential antibacterial secondary metabolites. This study aims to test the antibacterial activity of the ethyl acetate fraction of C. asiatica extracted by the soxhletation method against clinical isolates of P. aeruginosa and identify the secondary metabolites. The research used laboratory experiment using the disc diffusion method (Kirby-Bauer) in vitro. It includes 3 treatment groups with concentrations of 5.000 ppm, 7.500 ppm, and 10.000 ppm and 2 control groups: positive (colistin) and negative (DMSO 10%). The diameter of the inhibition zone served as an indicator of activity, and each group was reproduced five times. The biggest inhibitory zone diameter, with an average of 3 mm, was formed by the C. asiatica ethyl acetate fraction at a concentration of 7.500 ppm, according to the results. Secondary metabolites such triterpenoids, flavonoids, and phenolics were detected by phytochemical analyses. The ethyl acetate fraction of C. asiatica exhibited antibacterial activity against clinical isolate P. aeruginosa, as demonstrated by the significant difference between all concentration series with the positive control in the Mann-Whitney post-hoc test results.

Abstract

Microsatellites are short tandem repeat (STR) sequences that consist of simple repeats and exhibit a high number of alleles at each genomic locus. The aim of this study was to examine genetic variation in Bali cattle and the population dynamics using microsatellite markers. Two microsatellite loci, INRA032 and BM2113 were amplified using PCR Total DNA samples from the genome of 60 Bali cattle, then The PCR products were analyzed through agarose gel electrophoresis, followed by staining with Ethidium Bromide (EtBr). The number and size of alleles that appeared on the gel, while the diversity and population dynamics were analyzed using Popgene version 1.31 and Gene Calc. In this study, The effective number of alleles for the two microsatellite loci in the Bali cattle population analyzed was 6.53, with an average of 3.27. The average PIC of the two microsatellite loci was 0.70, while the observed heterozygosity (Ho) exceeded the expected heterozygosity (He), with values of 0.975 and 0.695, respectively. This suggests an excess of heterozygosity in the population and indicates that the populations are not in Hardy-Weinberg equilibrium. The inbreeding coefficient was high, with negative Fis values of -0.38 for INRA032 and -0.43 for BM2113.
