Abstract
Gembili (Dioscorea esculenta) is one of the tubers that contribute to local food diversification in Indonesia. This research addresses the limited knowledge on Gembili cultivation, a minor tuber with suboptimal utilization despite its high carbohydrate content. Reducing Indonesia’s dependency on rice can be achieved through tuber diversification like Gembili. Therefore, promoting land use for Gembili cultivation is essential. Developed gembili farming provides economic and ecological benefits. Economic benefits can be seen through the value of profitability, so that farmers can develop their farms. In terms of ecology, gembili supports environmental conservation by maintaining biodiversity and preventing land degradation. The crop also does not require intensive use of chemical fertilisers or pesticides, thereby reducing negative impacts on the environment and helping to maintain the balance of local ecosystems.This study aims to analyse the costs, revenues, and profitability as well as factors that affect the profitability of gembili farming in Watubonang Village. The location was determined purposively in Watubonang Village, Tawangsari District, Sukoharjo Regency. Sample determination totalled 34 respondents using the total sampling method. The data analysis method calculates the value of profitability and multiple linear regression analysis. Factors that are thought to affect the profitability of gembili farming are cropping patterns, the main occupation of farmers, labour costs, manure costs, NPK fertilizer costs, tool depreciation costs, and land rental costs. The results of the study can be concluded that the total costs incurred by farmers averaged Rp10,977,429.00 per Ha, receipts of Rp60,020,579.00 per Ha and profits of Rp43,100,056.00 per Ha . Quantitative results show that the profit from Gembili farming is Rp43,100,056.00 per hectare, with an income of Rp49,043,168.00 per hectare, profitability of 254.7%, a B/C ratio of 2.5, and an R/C ratio of 3.5, indicating that every 100 rupiahs spent yields a return of 254.7 rupiahs. The results of the regression analysis showed that the factors of cropping patterns, the main occupation of farmers, and labour costs individually had no significant effect on the profitability of gembili farming, and the cost of manure, the cost of NPK fertilizer, the cost of land rent individually had a positive effect on the profitability of gembili farming, and the cost of depreciation of equipment individually had a negative effect on the profitability of gembili farming in Watubonang Village, Tawangsari District, Sukoharjo Regency. Overall, gembili has the potential as a solution to strengthen food security and support profitable ecological conservation efforts.

Abstract
Dipterocarp species richness, floristic composition, and structure were studied in fifteen plots dispersed across 60 ha of Dramaga Research Forest in Bogor, Indonesia. The fifteen plots, each measuring 20m x 20m, evaluated all woody species in four growth stages (trees, poles, saplings, and seedlings) and the understory. This study aimed to determine the floristic composition, species diversity, community, and structural analysis that are important to provide necessary information on species richness and diversity in the study forest, and vegetation types that are useful for forest management purposes and help in understanding forest ecology and ecosystem functions. This research was conducted from February to June 2024. The site was conducted in the research forest, established in the 1950s, with the major species composition being Dipterocarps. This result showed 918 individuals from 48 species and 23 families. The top five families were Dipterocarpaceae, Meliaceae, Fabaceae, Arecaceae, and Calophyllaceae. Sapling’s growth stage showed the highest diversity levels (2.64) and richness (22.82) compared to other growth stages. All vegetation growth stages were recorded as having moderate diversity levels, meaning that the ecosystem conditions in the research forest tended to have moderate stability. This finding was similar to the conditions of dipterocarp forests in Southeast Asia, where the canopy layer of seasonal tropical rainforests is mostly composed of saplings to trees. The results also presented that fallen trees and unwanted ecotourism promote significant changes in the floristic and structural diversity in the different growth stages. The current composition and structure of the Dramaga research forest were similar to the original condition of the tropical dipterocarps forest habitat.

Abstract
Bats play an important role in the survival of the ecosystem, however, bats are also becoming reservoirs and vectors in the transmission of some human diseases. There are many genera of bacteria that have been reported to exist in the body of a bat and can infect a human being including Salmonella, Bartonella, Staphylococcus, Pseudomonas, and Neisseria. The study aimed to detect bacteria on the bat’s body and to evaluate its implications on tourism, especially tourism in the Special Economic Regions (KEK) of Mandalika. An observation was made from August 2022 to January 2023. Bat samples were taken at several nests in the bat’s natural habitat in Mandalika, between Kuta, Mertak, Prabu and Mekarsari villages. The observation of bacterial culture was performed from samples isolated from rectal swabs and blood collection. Carry Blair Transport Media was used as transport media. In the laboratory, samples were aseptically cultured in Soy Trypticase media and incubated at 37°C for 24 hours. The colonies were subcultured and examined on their colony characteristics, cell characteristics using Gram staining and biochemical characteristics using biochemical testing. Identification of the bacteria referred to Bergey’s Manual of Determinative Microbiology Ninth edition. From 90 bats caught, there were 5 species of the bats that were infected by bacteria, namely Cynopterus nusatenggara, Rosettus amplexicaudatus, Eonycteris spelaea, Rhinolopus acuminatus, and hipposideros diadema. There were 13 species infecting those bats including Kurthia sp., Shigella sp., Bacillus sp., Proteus sp. Proteus vulgaris, Clostridium sp., Serratia sp., Bacillus subtilis, Staphylococcus epidermis, Staphylococcus aureus, Eschericia coli, and Acinotobacter calcoaceticus were identified. In conclusion, the study highlights that various bacterial species inhabit bats in Mandalika, which may pose health risks to humans and have implications for tourism development in the area.

Abstract
The high volatility of essential oil on treated fabrics has received great attention from scientists due to its potential to reduce the effectiveness of mosquito repellency. To overcome this drawback, synthetic polymer has been used as binder to reduce the volatility of essential oil. However, these synthetic polymers are expensive and are not degradable naturally which have potential to pollute environment. These problems warn and motivate many researchers to search for a safer and more biodegradable binder. In this study, tragacanth gum, a biopolymer derived from plant, Astragalus gummifer, was used in the nanoemulsion that later treated with fabrics. We investigated the efficacy of cotton and polyester treated with tragacanth gum loaded with lemongrass essential oil nanoemulsion. Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), zeta potential, and polydispersity index were used to characterise the nanoemulsion formulation. Meanwhile, scanning electron microscopy (SEM) was used to analyse the treated fabrics. The results showed that tragacanth gum loaded with lemongrass essential oil exhibits 94% encapsulation efficiency with a -35.23 mV zeta potential and 0.2 polydispersity index. In conclusion, tragacanth gum loaded with lemongrass essential oil nanoemulsion was successfully developed. Nanoemulsion recorded a good stability, was able to prolong the release of lemongrass essential oil and had a high level of retention on fabrics towards washing and heating process. Results conclude that nanoemulsion could be used for the delivery of hydrophobic compounds and is able to increase the effectiveness of essential oil.

Published: December 2024

Abstract
Medical imaging is pivotal in early disease diagnosis, providing essential insights that enable timely and accurate detection of health anomalies. Traditional imaging techniques, such as Magnetic Resonance Imaging (MRI), Computer Tomography (CT), ultrasound, and Positron Emission Tomography (PET), offer vital insights into three-dimensional structures but frequently fall short of delivering a comprehensive and detailed anatomical analysis, capturing only amplitude details. Three-dimensional holography microscopic medical imaging provides a promising solution by capturing the amplitude (brightness) and phase (structural information) details of biological structures. In this study, we investigate the novel collaborative potential of Deep Learning (DL) and holography microscopic phase imaging for cancer diagnosis. The study comprehensively examines existing literature, analyzes advancements, identifies research gaps, and proposes future research directions in cancer diagnosis through the integrated Quantitative Phase Imaging (QPI) and DL methodology. This novel approach addresses a critical limitation of traditional imaging by capturing detailed structural information, paving the way for more accurate diagnostics. The proposed approach comprises tissue sample collection, holographic image scanning, preprocessing in case of imbalanced datasets, and training on annotated datasets using DL architectures like U-Net and Vision Transformer(ViT’s). Furthermore, sophisticated concepts in DL, like the incorporation of Explainable AI (XAI) techniques, are suggested for comprehensive disease diagnosis and identification. The study thoroughly investigates the advantages of integrating holography imaging and DL for precise cancer diagnosis. Additionally, meticulous insights are presented by identifying the challenges associated with this integration methodology.

Abstract
Capacitive sensing of electrophysiological signals is a promising alternative to traditional contact-type sensing for long-term and ubiquitous health monitoring. Many researchers are focusing on developing flexible capacitive electrodes to improve the conformability and the quality of acquisition of this family of sensors. However, current flexible devices still present many limitations due to the negative Poisson’s ratio of the materials used, which affects the dimensions and characteristics of the materials when under stress, and their incompatibility with traditional manufacturing methods and solid-state devices. We present a novel, inkjet-printed, hybrid capacitive Kirigami sensor design. This novel structure comprises different layers with different functionalities, in order to allow improved flexibility and conformability of the flexible Kirigami printed electrode, while securing its inclusion on a traditional rigid printed circuit board for a quality signal acquisition. The novel sensor design has been tested on different shapes and dimensions of sensing target and with different weights applied. Capacitive and electrical measurements were performed to obtain the main basic sensor characteristics such as coupled capacitance, acquired signal amplitude and cutoff frequency. When compared to an analog but rigid sensor, the novel designed hybrid flexible sensor showed significant improvement and enhanced uniformity of measurements, with an increase in amplitude value up to

Published: December 2024

Abstract
This study examines the characteristics of single-wall carbon nanotube (SWCNT) antennas in both flat and bent configurations to comprehensively assess their properties as practical flexible antennas. Monopole antennas solely composed of SWCNT were fabricated, characterized by their high flexibility, light weight, and mechanical robustness. These antennas were tested under conditions representative of the operational environment of flexible antennas, and their reflection and radiation characteristics were analyzed. The gains of the SWCNT antennas, whether flat or bent, were nearly identical, and their radiation patterns were similar to those of traditional metal antennas. Using the Wheeler cap method, the radiation efficiencies for the flat and bent SWCNT antennas were measured at 80.0% and 83.7%, respectively, exceeding the 80% threshold considered practical for such applications. The high flexibility and efficiency of the antennas render them suitable for integration into wearable devices and other applications demanding non-standard shapes and surfaces.
