Abstract

Traditional herbal medicinal plants are natural ingredients that come from plants and have been used for generations for medicinal purposes. This study aims to analyze the utilization of plants as traditional medicinal materials by the community in the Kerandangan Nature Park, West Lombok. Using a descriptive qualitative method through observation and interviews, it seeks to obtain in-depth information about the community's behavior in utilizing plants as medicine and employs the Shannon-Wiener diversity index to analyze the species diversity of medicinal plants. The study found 20 plant species from various families such as Zingiberaceae, Piperaceae, Rutaceae, Fabaceae, Lamiaceae, Asteraceae, Poaceae, Verbenaceae, Rubiaceae, Myrtaceae, and Caricaceae being used by the community to treat various diseases. The diversity level of medicinal plant species was categorized as moderate. The commonly used parts of the plants include leaves, rhizomes, fruits, stems, flowers, and roots. This indicates that the community of Dusun Kerandangan still utilizes medicinal plants to cure various ailments that have been traditionally used for generations, despite the ongoing development of modern medicine.

Abstract

Pearl oysters (Pinctada maxima) are an aquaculture commodity with high economic value. Large-scale production of pearl oyster seeds remains a challenge due to low growth and survival rates. Salinity is an environmental factor that greatly influences growth, feed filtration rate and survival of bivalves. This study aims to evaluate the effect of salinity levels on the growth, survival and filtration rate of pearl oyster spat. Pearl oyster spats measuring 2.14 ± 0.77 mm (dorso-ventral) were reared for 21 days at salinities of 26, 30, 34, and 38 ppt with a single feed of Chaetoceros amami with an initial density of 20,000 cells/ml. The results showed that a salinity of 34 ppt produced the highest growth and was significantly different (p < 0.05) compared to other salinities with an absolute growth value of 6.18 ± 0.25 mm, relative growth of 288.8 ± 11.5% and the daily specific growth rate is 6.68 ± 0.15% per day. The feed filtration rate value at a salinity of 34 ppt was 126.76 ml/hour/individual with a survival rate of 94.22% where these two parameters were also significantly different compared to other salinity treatments. There is a close relationship between growth, filtration rate and survival of spat with the salinity level of the rearing medium. This research shows that salinity of 34 ppt is the optimal condition to support growth, feed filtration rate, and survival of pearl oyster spat.

Abstract

Garlic is a herbal plant that is widely used as a medicinal ingredient, because it contains secondary metabolite compounds such as alkaloids, flavonoids, tannins, phenols, terpenoids and saponins. The secondary metabolite content of plants is influenced by genetic, ontogenic, morphogenetic and environmental factors that can influence the biosynthesis and accumulation of secondary metabolites. Garlic is generally only used for the bulbs, while other parts such as the leaves and skin are still not widely used. This study aims to identify the secondary metabolite profile of ethanol extract of garlic leaves, bulbs and peels using the gas chromatography mass spectrometry (GC-MS) method. Identification of secondary metabolite compounds contained in each 70% ethanol extract was analyzed using the tube test, thin layer chromatography (TLC) and GC-MS methods. The results of analysis of secondary metabolite content using the tube test and TLC method showed that the ethanol extract of garlic leaves, skin and bulbs positively contained flavonoids, tannins, phenols and saponins. The results of secondary metabolite profile analysis using the GC-MS method from the ethanol extract of garlic skin and bulbs showed that 5 compounds were obtained with the main compound being 3,4-Dihydroxyphenylacetic acid and 23 compounds with the main compound being 1,2-Benzenedicaboxylic acid and palmitic acid, while the leek extract white only detected 1 compound. The conclusion is that the ethanol extract of garlic leaves, skin and bulbs has secondary metabolites in the form of flavonoids, tannins, phenols and saponins. There are differences in the profile of secondary metabolite compounds in the ethanol extract of garlic leaves, skin and bulbs in terms of the results of GC-MS analysis.

Abstract

Aquilaria malaccensis is a member of Thymelaceae family which is one of the main trees producing agarwood compounds in Indonesia and has high economic value. A. malaccensis has Appendix II conservation status due to high exploitation in the nature.  One of the several efforts to maintain agarwood production while also maintaining agarwood population is efficient induction by manipulation of the pathway for agarwood formation and using individuals with higher production of agarwood compounds. Selection of superior individuals can be done using molecular markers that are linked to certain genes, including microsatellites or simple sequence repeats (SSR). This study aimed to identify SSRs in the agarwood transcriptome and characterized SSR sites that are linked to genes involved in the synthesis of agarwood compounds. The transcriptome data used was extracted from the NCBI database with accession number GHJS00000000.1. SSR mining was carried out using Krait v.1.4.0 software, then BLASTed with the protein database to analyze the linkage with the related genes. Perfect SSRs were found in 0.37% of the total sequences, and compound SSRs were 10.89%. The abundance of imperfect SSR (107,043) was greater than perfect SSR (31,262), indicating that SSR in the transcriptome had a low mutation rate and the SSR site was more conserved in A. malaccensis. The SSRs that linked to genes related to agarwood synthesis including HMGR, PAL, Mevalonate Kinase, MAPK, Delta-guaiene synthase, Farnesyl pyrophosphate synthase, and Phenylalanine ammonia-lyase. The discovery of SSRs linked to these genes can be used to create molecular markers that can be applied in agarwood producing trees selection.

Abstract

Malnutrition is a condition in which the body is deficient or excessive in macronutrients and micronutrients such as carbohydrates, fats, proteins and vitamins. Malnutrition causes changes in body weight and blood tissue that inhibit the development of hematopoietic cells, resulting in anemia, leukopenia and bone marrow hypoplasia. This study aimed to examine the effect of feeding a diet with a protein level of 12% and 20 % for 6-week to Wistar rats. The parameters seen are the impact on body weight and selected hematological parameters included white blood cell, monocyte, lymphocyte, granulocyte, hemoglobin and mean corpuscular volume. This study found that rats fed with 12% protein showed significant differences in body weight and several hematological parameters such as monocytes, lymphocytes, hemoglobin and mean corpuscular volume compared to normal.

Abstract

Rembangan Dairy Farm, which is located at UPT Livestock Breeding and HPT Rembangan WM8R+734, Darungan, Kemuning Lor, Kec. Arjasa, Jember Regency, East Java, is a cow's milk processing industrial area. The purpose of this study is to find out how the agro-industry forms in Rembangan Dairy Farm. The research method applied in this study is qualitative research with a case study approach. Data collection techniques through observation, interviews and documentation. Data analysis uses descriptive analysis according to the facts found in the field. The results of this research are that the milk processing process in industry still uses a simple method, namely the pasturization stage. The dairy products produced consist of two types, namely pure fresh milk without any additions and fresh milk with a variety of flavors. Milk marketing techniques are carried out online via social media Instagram and Whatsapp, and also offline through milk outlets and business partners. Marketing of fresh milk by business partners needs to be further improved in maintaining the durability of milk using refrigerators or freezers, this is because fresh milk is susceptible to temperature so it can easily spoil if not stored in the correct way. There is a need for further education for business partners to be able to maintain product quality by storing it properly so that the products being marketed do not suffer damage when in the hands of consumers.

Abstract

The diversity of aquatic microorganisms was an important component in aquatic ecosystems, because they play a crucial role in biogeochemical cycles and ecological balance. These microorganisms can reflect the condition of the aquatic evirontment and be an indicator of ecosystem health. On the other hand, the physiscal conditions of water such as temperature, pH, and brightness greatly influence the presence and activity of these microorganisms. This research used survey and consecutive sampling methods. Sampling was carried out at two stations, namely in the upstream section located in Sumber Sari village, South Metro Ditrict, Metro City and in the downstream section located in Banjarrejo Village, Batanghari District, East Lampung Regency. The results of research carried out on the Way Batnghari tributary obtained and average temperature value of 29,5ºC in the upstream section and average temperature value of 28,6ºC in the downstream section. In terms of brightness, the upstream section has a better brightness with a value of 25 cm compared to the downstream section which has a lower brightness of 20 cm. The pH value in the downstream section is 6,7 slightly more acidic than the upstream section which has a normal pH level of 7,2. The diversity index of microorganisms in the Way Batanghari Metro tributary obtained a diversity index of 1,24 in the medium category. This value shows that the Way Batanghari tributary is included in the moderatelly polluted category.
