Abstract

The availability of groundwater is an important factor in meeting the need for clean water for human populations and ecosystems. Groundwater utilization in the world continues to increase every year along with the increase in population. This study aims to identify groundwater potential using resistivity geoelectric method with Schlumberger configuration in Pujut District, Mertak village. This area is one of the areas that often experiences drought, especially during the dry season. The research was conducted by conducting field surveys using geoelectric devices and resistivity data analysis. This method utilizes the propagation properties of electric current flowed into the soil through two current electrodes, then the potential difference that occurs is measured through two potential electrodes plugged into the ground surface. Analysis of resistivity data yielded a picture of the potential distribution of groundwater in six sites.  The identified characteristics of subsoil are breccia, loam, limestone, alluvial, and sandstone. At locations 4,5 and 6 have aquifer layers with an average depth of 30 meters. This layer is dominated by a hard layer (sandstone) and a soft layer (limestone). This research provides a better understanding of the distribution and characteristics of aquifers in the Pujut area, especially Mertak village, so that the results of this research can be the basis for making decisions on groundwater resources management and further development in mapping groundwater resources in the region with other geological contexts.

Abstract

Natural Resistance-Associated Macrophage Protein 1 (NRAMP1) is a gene that regulates the body's resistance to illness. The genetic diversity of Kampung and KUB chicken population in Lombok island West Nusa Tenggara province was investigated based on g.3768T>C loci of NRAMP1 gene. Experimental animal consisted of 105 KUB and 67 Kampung chickens. The NRAMP1 gene polymorphisms in both population were identified using PCR-RFLP method. Genetic parameters of g.3768T>C loci were calculated using PopGene32. In this study, the locus g.3768T>C of the NRAMP1gene found three genotypes (TT, CT, CC) with the frequency of the C allele was higher than the T allele, respectively 0.709 and 0.210 in Kampung chicken, and 0.738 and 0.262 in KUB chicken. The mean value of observed heterozygosity (Ho) and expected heterozygosity (He) of g.3768T>C loci in both populations revealed low to medium genetic diversity, with the values 0.222 and 0.400, respectively. The mean value of observed heterozygosity is lower than expected, indicating that the population is heading towards a heterozygosity deficit and proving that the two populations are not in Hardy-Weinberg equilibrium. The mean PIC value of the NRAMP1 gene (g.3768T>C) in both chicken population was 0.319 and classified as fairly informative (0.50 > PIC > 0.25). Meanwhile, the value of the genetic differentiation index (Fst) for Kampung and KUB chicken population were 0.385 and 0.433, indicating that there is differentiation between two chicken population at the observed loci.

Abstract

Scylla serrata is one of the species included in the mangrove forest ecosystem which has high economic value for human life. Seeing that mud crabs have high economic potential both domestically and abroad with a fairly high level of demand and abundant availability of catches in nature, concerns arise about the condition of their population. This research aims to determine the population structure of mangrove crabs in the Bagek Kembar Mangrove Forest Area, West Lombok. The method used is purposive sampling. Sampling was carried out at 3 stations representing the entire research location area, namely on the seafront, in the middle and farthest from the arena facing the sea. Each station has its own characteristics. The distance between stations is 50 m. Each station is installed 6 folding trap with a distance between trap 10 m. The length, width, and high size are 50 cm, 30 cm, and 15 cm respectively. This tools are completed by 3 mm mesh size. The results of the research showed that the carapace length of male and female mud crabs that were mostly caught was in the 3 – 4.5 cm and 2.5 – 4.0 cm classes. The carapace width of male and female mud crabs most often caught is in the range of 4.4 – 6.5 cm and 3.5 – 5.5 cm. And the weight of the most commonly caught male and female mud crabs was in the class range of 11.39 – 111.5 grams and 13.77 – 74.5 grams. This research concludes that mangrove crabs that live in the Bagek Kembar Mangrove Forest Area, West Lombok, based on gender, carapace length, carapace width and body weight, are dominated by juveniles. Only a limited number reach catch size.

Abstract

Currently, the threat to sea turtle conservation is still quite high both by natural and anthropogenic (human) factors. Therefore, we try to make efforts in sea turtle conservation, through transferring sea turtle eggs to a semi-natural nest. Subsequently, the rearing of hatchlings that successfully hatched from semi-natural nests. Based on these factors, it is important for us to know how to preserve Lepidochlys olivacea and to analyze the physical and chemical parameters of hatchling rearing. The method of rearing the sea turtles after hatching at the research site has 3 stages, namely moving the newly hatched baby turtles from semi-natural nests to the rearing tanks, 30-day rearing actions in the holding tanks (feeding, changing water, and checking water quality) and releasing the sea turtles to their natural environment, namely the open sea. From the data that has been taken for 30 days, the average temperature results were found to be 26-28oC, for salinity data of 22-25 ppm and for DO data of 7.7-7.9. The measured DO data is still under the range of PP 22 of 2021 Appendix VIII concerning the Implementation of Environmental Protection and Management.

Abstract

The Indonesian people are familiar with the herbaceous vegetable plant known as basil (Ocimum basilicum L.). The leaves of the basil plant are typically used to flavor cuisine and as fresh vegetables. This study set out to determine how applying liquid organic fertilizer from eco farming affected basil plants' ability to grow vegetatively (Ocimum basilicum L.) as well as the optimal dosage for this growth. August and September of 2023 saw the completion of this study. Using three treatments and five replications, the research employed a Randomized Block Design (RAK) methodology. Treatment A0 was the control, receiving no fertilizer; treatment A1 received 4 milliliters of eco-farm fertilizer; and treatment A2 received 6 milliliters of eco-farm fertilizer. The characteristics that need to be taken into account include plant height, number of branches, leaf area index, number of leaves, initial and final soil analysis, and chlorophyll content. The study data will be analyzed using statistical products and services solutions (SPSS) software version 25. The administration of 6 milliliters of eco-farm fertilizer to plants, or treatment A2, had a significant effect on the vegetative development of Ocinum basilicum L. basil plants, according to the research findings. Measurements of plant height are affected by a concentration of 6 ml. The highest average value for number of leaves is 30.00, while the highest average value for height is 39.60, the highest average value of 3.35 for leaf area index, and the highest average for leaf area index. 4.0 for number of branches.

Abstract

Improving the production of organic rice can be achieved by using certified superior seed varieties. The research aimed to test the adaptability of several superior rice varieties in organic farming systems to obtain varieties suitable for rice growth and yield in the Cipatujah District of Tasikmalaya Regency. A single-factor randomized complete block design was used in this study to test 3 superior varieties, namely Ciherang, Inpari 32, and Mekongga varieties. Each treatment was replicated 20 plots, resulting in a total of 60 experimental plots. The analysis results indicated that the soil at the demonstration plot location met land suitability and rice plant growth requirements with S1 (very suitable) criteria based on parameters such as pH, organic carbon content (C-organic), nutrient content of Nitrogen, Phosphor, and Potassium, bulk density, particle density, porosity, and soil texture. The superior variety treatments had a significant impact on plant height growth, although there were no significant differences observed in terms of tiller number, productive tiller number, grain yield per hill, filled grain per hill, grain weight per hill, and 1000-grain weight. The Ciherang variety showed the highest plant growth response and larger yield components compared to Mekongga and Inpari 32. The use of certified seeds in organic rice cultivation practices was proven to yield higher results compared to seeds from previous cultivation practices.

Abstract

Non-Timber Forest Products (NTFPs) are a part of forest ecosystem which have various roles, both in the natural environment and in human life. The NTFPs usually used as the basis for alternative economic value of a forest, and the demand for NTFPs are related to forest management. Plants are often  used as NTFPs, and the highest demand of the products is handicraft that are bought and sold across economic centers, but the detail information about the NTFPs and their derivative products in those capital areas are less known. This research investigates the use of NTFPs for craft products in Padang Panjang City, West Sumatra, Data on plant species, the derivate craft products, the part of plant used, sizes, water content, the demand for raw material for each product, place of origin, and the prices were colleted directly to all three existing craft shops in Padang Panjang City. Four plant species were found for making 17 types of craft products, namely bamboo (Bambusa spp.), rattan (Calamus spp.), coconut (Cocos nucifera L.), and pandan (Pandanus spp.). The most craft products was made from rattan, and the most part of plants used was the stem, which less than 30 mm in size, and below 14% in water content. Coconut and Pandan was found as fruit and leaves. Only two of 17 products were made locally in Padang Panjang.  The results of this research show that rattan as a type of NTFPs that mostly commercialized for craft products in Padang Panjang City. This data can be used for communities living at forest adjacent around Padang Panjang City on extracting the NTFPs.

Abstract

Family medicinal plants (TOGA) are a form of traditional medicine still used independently by the community, especially by people living on the city's outskirts. Tebang Kacang Village is one of the villages within the administrative area of Kubu Raya Regency, but it is located on the outskirts of Pontianak. This research aims to analyze the use of family medicinal plants in the Tebang Kacang Village community, which is close to the provincial capital and has easy access to modern health facilities. A total of 311 respondents selected using purposive sampling were interviewed in-depth and with a questionnaire as a guide. They were asked about the use of family medicinal plants.The study results show that the people of Tebang Kacang Village still use medicinal plants, especially plants planted and cultivated around their home gardens and gardens or what is known as TOGA. The community used 75 species of plants belonging to 38 plant families. These plants are used not only to treat various diseases but also to care for people's health. The community also uses this family of medicinal plants as food in the form of vegetables and fruit. The people of Tebang Kacang Village mostly use the leaves (45%) and fruit (20%) of TOGA to make medicinal concoctions. These medicinal concoctions are generally prepared by grabbing (51.14%) and used by drinking (53.93%). This research shows that even though this village is relatively close to urban areas, people still choose to use medicinal plants to treat various diseases and maintain health. TOGA is the first choice of treatment.
