Abstract

Degraded land affects almost all ecosystems and can harm the progress and quality of human life, so it needs attention. Saline soil is a land degradation with high salt content that causes toxic effects, increases root osmotic pressure, and inhibits plant growth. One solution is using organic mulch processed into biogeotextiles because it can provide solutions for erosion control and soil stabilization while minimizing negative impacts on the ecosystem. This research was conducted from May to August 2023 in the experimental garden of the Faculty of Agriculture UPN ‘Veteran’ East Java. This study used a group randomized design with one factor,  the type of geotextile material consisting of reed grass (RG), straw (ST), pandanus odorifer (PO), and sugarcane bagasse (SB). This research was conducted with a litterbox of 20x20 cm filled with 100 g of biogeotextile material. The results obtained show that pandanus odorifer biogeotextile material is the best biogeotextile material because it can last a long time on the soil surface, but can still be adequately mineralized, according to the results obtained, reducing the C/N ratio and C-Organic but increasing total nitrogen. Decomposition is closely related to the materials’ quality rather than external factors. The quality of the material, namely lignin, organic carbon, C/N ratio, and nitrogen, influences the decomposition process. Furthermore, this technology can be applied to improve soil productivity and to keep soil healthy.

Abstract

Nitrogen deficiency dramatically affects plant growth, development, and productivity. This study aims to determine the utilization of Trichoderma sp. and compost in increasing the nitrogen content of several types of soil used as planting media. The research was conducted using an experimental method arranged in a completely randomized design (CRD) factorial pattern. The first factor is the soil types, namely Alfisol, Inceptisol, and Vertisol. The second factor is dose of compost consisting of 4 levels, namely K1 (0 tons ha-1 or no compost), K2 (10 tons ha-1), K3 (20 tons ha-1), and K4 (30 tons ha-1). The third factor is the concentration of Trichoderma sp., which consists of 4 levels, namely T1 (0 CFU ml-1), T2 (106 CFU ml-1), T3 (108 CFU ml-1), and T4 (1010 CFU ml-1). Results showed that the combination of compost and Trichoderma sp. had a natural effect on increasing the N content of each soil type. N-total content from highest to lowest was found in soil types such as Inceptisol (0.384%), Alfisol (0.243%), and Vertisol (0.230%). Combining compost and Trichoderma sp. increases sustainable nitrogen availability and is more environmentally friendly.

Abstract

This article examines the use of role-play in teaching pragmatic skills to the vocational students with the aim of promoting authentic interaction from Indonesian vocational students of English as a foreign language (EFL). The investigation adopts a qualitative perspective, as it recognizes the constraints of pre-set scripts in cultivating context-specific communication skills, by analyzing how student-generated role play in diverse contexts may cultivate pragmatic attunement and facilitate participation. Students in the fourth semester of an English for Tour and Travel class worked together to design workplace communication tasks based on video models and real-life experiences. Research data included classroom observations, video recordings of students’ performances, and post-project interviews. It is found that the students progressed in the use of speech acts, politeness strategies, and turn taking in spoken interactions. These roles play activities enabled not only improvised speech practice and peer feedback but also provided an opportunity for language learners to reflect cultural norms and communication intentions. The research reinforces the importance of moving away from static textbook discussions to the dynamic real-world tasks that approximate actual use of the language. It points to the need for the inclusion of pragmatic competence in speaking instruction, especially in vocational EFL contexts where work-related communication and sociopragmatic awareness are important.

Abstract

This study aimed to develop resistance in shallot (Allium cepa) against twisting disease caused by Fusarium oxysporum by applying microorganism-based biopesticides. By inducing resistance in shallots, the research sought to explore the pathogen-host interactions, understand infection mechanisms, and establish sustainable disease management strategies. Utilizing a biopesticide approach within an organic farming framework, this study aimed to assess the effectiveness of biopesticides in inducing plant defense mechanisms. The experimental design was non-factorial and followed a randomized block structure, consisting of four treatments with three replications each: (A) Chemical pesticide and fertilizer, (B) Biopesticide applied to seeds and plants, with chemical fertilizers on soil, (C) Soil sterilization with biopesticide and pesticide application on plants, and (D) Soil sterilization with biopesticide, with biopesticide applied to seeds and plants. Observations focused on disease intensity and salicylic and jasmonic acid levels in shallot bulbs. Results demonstrated that biopesticide application successfully reduced disease incidence and increased resistance, as shown by higher levels of salicylic and jasmonic acids in treated plants. The study concluded that biopesticides are promising for enhancing systemic resistance in shallots.

Abstract

One of the treatments for appendicitis is surgery. Surgery will certainly cause post-operative pain that needs to be handled appropriately. If it is not treated immediately, pain in post-operative patients will slow down patient recovery, results in long hospitalization, prone the patient to a high complication rate, and require a lot of costs. Therefore, proper handling of post-operative pain is needed. In addition to drugs, non-pharmacological techniques can be a supportive treatment that proven to be effective. A non-pharmacological technique that can reduce pain is finger grip relaxation therapy. This study aims to describe the nursing care in a case of patient with post-operative appendicitis given finger grip relaxation therapy to reduce pain. This is a descriptive case study of an adult postoperative appendicitis patient with major nursing problems, acute pain. Results showed that the patients suffering level 6 of pain (moderate pain). The patient was given intervention including analgesic and supported with hand-held finger grip therapy in three days. The intervention was given three times a day, with a duration of 30 minutes. After given the intervention, the patient reported a decrease in pain level, into level 1 (mild pain). It can be concluded that nurses can apply finger grip relaxation therapy to provide nursing intervention or nursing care for post-operative patient to accelerate pain relief.

Abstract

Soil characteristic and properties are essential determinants for effective land management. Soil genesis results from the interaction of various pedogenic factors, which are influenced by environmental conditions, thereby producing diverse soil types in different locations. This study was conducted in the Wonosalam sub-district, an area characterized by diverse regional conditions due to its varied physiographic features. The physiographic and climatic conditions in this region significantly influence soil formation processes. This research focused on monitoring soil development at several locations within Wonosalam, specifically at the UPN "Veteran" Jawa Timur experimental field. The study included five observation points, categorized by land map units: PW1, PW2, PW3, PW4, and PW5. Morphological analyses indicate the presence of two distinct soil types among the five observation points. The soils in PW1, PW2, PW3, and PW4 are classified under the Alfisols order, specifically within the Typic Hapludalf subgroup. In contrast, the soil at PW5 belongs to the Inceptisols order, specifically the Typic Humudepts subgroup. This diversity suggests that the area encompasses soils of different orders. The soil characteristic data obtained from the UPN "Veteran" Jawa Timur experimental field can be utilized as a basis for planning the management of the area.
