Abstract

Nematodes are soil organisms that play an essential role in agricultural ecosystems, both as plant pathogens and soil health indicators. Non-parasitic nematodes or free-living nematodes play an essential role in soil food webs. This study aims to analyze the diversity and population of non-parasitic nematodes in Piper nigrum L. from various pepper accessions on Bangka Island. soil samples taken from seven locations and extracting nematodes using centrifugation flotation techniques. Nematodes were identified based on morphological characteristics by using a stereo and binocular microscopes and validated to the nematode identification keybook. The population of identified nematodes was calculated using the absolute population calculation formula. The results showed variations of non-parasitic nematodes in each location, which were influenced by environmental factors and types of pepper accessions. The most dominant population of identified nematodes was classified as Rhabditidae with 92.42%, Mononchidae, and Aphelenchus avenae (92.42%). The nematode population in Lampung Daun Lebar accession was 41 individuals, Lampung Daun Kecil (17), Nyelungkup (9), and Merapin (healthy control) 65 individuals. Non-parasitic nematodes have roles as bacterivores (soil bacteria eaters), fungivores (soil fungus eaters), predators of parasitic nematodes, and decomposers in the soil.

Abstract

Modern agriculture demands efficiency and accuracy in resource management, particularly in monitoring soil moisture and the content of essential macronutrients such as nitrogen, phosphorus, and potassium. This study aims to design and implement a plant monitoring and control system based on the Internet of Things that integrates soil moisture and NPK sensors. The system is designed to collect real-time soil condition data and transmit it to an XAMPP server, allowing smartphone access via a web application. The research method includes hardware and software design, sensor testing, data analysis of the monitoring results and the automatic control of irrigation and fertilization. Data analysis is carried out by comparing sensor measurement results with the standard requirements of the plants. The test results show that the system can effectively monitor and control plant conditions, provide accurate information, and facilitate remote agricultural management. In conclusion, this system can improve the efficiency of water and fertilizer use and crop productivity, thus supporting precision and sustainable agriculture.

Abstract

This study aims to see how the role of the environment on the self-confidence of students who experience body shaming, with a focus on students who experience body shaming treatment at IAIN Bengkulu. be a case of discussion, namely the role of the environment to foster self-confidence of students who get body shaming treatment. With a positive environment so that it can provide motivation and understanding to students who are victims of body shaming such as the support from a positive friendship environment so that it can provide understanding to students who experience body shaming to keep thinking positively and accepting themselves and being confident.

Abstract

Rice plants typically grow in paddy fields, but they can also be cultivated in dryland areas, known as upland rice. This study aims to examine the effect of applying the micronutrient boron on the growth and morphological characteristics of two rice varieties, IPB 3S and IPB 9G, conducted at the Leuwikopo experimental field of IPB using the legowo planting system. The treatments consisted of four combinations: no boron application on IPB 9G and IPB 3S varieties, and boron application on both varieties. Boron was applied at a concentration of 20 ppm through foliar spraying on the lower leaf surface three times during the growing period. Observations were made on plant characteristics, including leaf shape and position, plant height, number of tillers, flowering age, panicle exertion, and grain characteristics. Based on the results, it can be concluded that rice grain filling is influenced by pollen production and viability, which can increase the percentage of filled seeds and seed production. However, the production results in this study could not be analyzed due to bird pest attacks, which resulted in the absence of harvest data. Therefore, further research is recommended with more optimal plant protection to accurately obtain seed production data.
