Photographic Representation in Independent Comic “Cabin” and “Left Behind” by Azisa Noor. Independent comics are comics created and published by the creators themselves and are not tied to the publisher's interests. Several independent comics present a series of visual narratives using elements like photograph drawings or photographic imageries. The photographic imagery in question is an illustrative depiction representing photographic media, not a scene visualization technique using photographic techniques. This research aimed to investigate the report and function of photographic imageries in the visual narrative of independent comics in Indonesia, especially in the work of Azisa Noor; Cabin (2016) and Left Behind (2017) were selected using a purposive sampling technique. The research used qualitative methods, with textual analysis based on the semiotics of Mario Saraceni's comic language, which is presented descriptively based on a

Identification of Cave Biota Using High Key Technique Photography. Photography is recording reflected images produced from objects illuminated by light through a device called a camera. According to Ben, (Ben Brain 2012) Photography using the high key technique is a photo that is dominated by white. High key has a function to simplify the background, making the observation/identification process easier. Cave biota is important to discuss because it functions as an indicator of biodiversity and ecosystem balance in caves. According to Cahyo (Cahyo R. 2021) Cave biota experiences physiological and morphological adaptations due to having to survive in the unique conditions and environment of caves. These forms of adaptation are regressive and progressive. Progressive adaptations include: eyes that become smaller or disappear altogether, loss of body pigment, loss of wings in several groups of insects; regressive adaptations in the form of: elongated antenne or legs and increased sense of taste such as the number and/or fine hairs on the surface of the body, trichobothria. This journal discusses how to carry out practical photography that will be used as a medium for identifying biota, including the techniques used, equipment and methods. The methods for this research were collecting cave’s biota samples, conducting photography practice, and making identification. Then, photos of cave biota were identified using a determination book and described according to the taxonomy of each type.
利用高调摄影技术识别洞穴生物群。摄影是通过一种称为照相机的设备记录物体在光线照射下产生的反射图像。根据 Ben 的说法（Ben Brain，2012 年），使用高调技术拍摄的照片以白色为主。高调的作用是简化背景，使观察/识别过程更加容易。洞穴生物群是洞穴生物多样性和生态系统平衡的重要指标，因此有必要对其进行讨论。根据 Cahyo（Cahyo R. 2021）的说法，洞穴生物群由于必须在洞穴的独特条件和环境中生存，会经历生理和形态适应。这些适应形式有渐退和渐进两种。渐进式适应包括：眼睛变小或完全消失、身体色素丧失、几类昆虫失去翅膀；后退式适应的形式包括：触角或腿变长、味觉增强，如身体表面细毛的数量和/或三毛。本日志讨论了如何进行实用摄影，将其作为识别生物群的媒介，包括使用的技术、设备和方法。本研究的方法是收集洞穴生物群样本、进行摄影实践和鉴定。然后，使用判定书对洞穴生物群的照片进行鉴定，并根据每种类型的分类进行描述。

Technical and Creative Photographics Elements in the Visual Representation of Architectural CGI. Technological developments have caused the result of image creation in photography and Computer-Generated Imagery (CGI) on architectural contexts to become increasingly similar. This issue was made as the background for research on CGI's technical and creative photographic elements. The similarity between photography images and CGI makes it challenging to differentiate between the two, thus raising the question of whether photographic elements are applied in architectural CGI images. Therefore, research was carried out to show photographic elements in architectural CGI images' technical and creative scope. The study was conducted using qualitative methods and presenting data descriptively. The analysis results showed that in architectural CGI, visible photographic elements are starting from the image creation process to the architectural CGI image results by applying technical and creative aspects directly or indirectly.

In the Silence: An Inspirational Story of Fikri’s Struggle, the Deaf Boy, in Narrative Photostory. Fikri is a nineteen-year-old boy who has been deaf since birth. He becomes the main character in this narrative photo story because he is considered extraordinary and an inspiration to other deaf people. Fikri works and earns money as the breadwinner for the whole family, considering that both of his parents are also deaf and they do not have a job. This research aims to create narrative photostory that can convey the author's perspective on Fikri in order to make the readers to have the same perception as the author. The benefit of this research is as a practical application of narrative photostory theory with Fikri as the deaf person as the subject. The method used in this research was descriptive qualitative, done by exploring or photographing social situations which were thoroughly, broadly, and deeply examined. The data was collected from observation, interviews, surveys, and literature studies.
在沉默中聋哑男孩 Fikri 的奋斗励志故事，摄影叙事。菲克里是一个 19 岁的男孩，自出生起就患有耳聋。他之所以成为这个叙事摄影故事的主角，是因为他被认为是一个非凡的人，是对其他聋人的一种激励。考虑到他的父母也都是聋人，而且没有工作，Fikri 作为全家的经济支柱工作赚钱。本研究旨在创作叙事摄影故事，传达作者对 Fikri 的看法，使读者与作者有相同的感知。本研究的益处在于以聋人 Fikri 为研究对象，实际应用叙事摄影故事理论。本研究采用的是描述性定性研究方法，通过探索或拍摄社会情境，对其进行全面、广泛和深入的研究。数据收集来自观察、访谈、调查和文献研究。

Extraction and study of the optical properties of natural dyes from several plant parts such as leaves, flowers, tubers, and fruits have been carried out using a simple maceration method and UV-Vis absorption characterization. The samples were divided into several groups in this study, namely the flower group (Tagetes sp., Paeonia sp., Centaure sp., Chrysanthemum sp., Carthamus tinctorius, Gomphrena globosa, Myosotis sylvatica, Lavandula sp., Clitoria ternatea, Matricaria chamomilla, Hibiscus sabdariffa, and Rosa sp.); the leaf group (Mangifera indica, Moringa oleifera, Graptophyllum pictum, Spinacia oleracea, Citrus hystrix, and Terminalia sp.); and the tuber and fruit group (Solanum lycopersicum, Cucurbita moschata, Garcinia mangostana, Curcuma longa, Beta vulgaris, and Caessapina sp.). The extract of natural dyes was successfully produced using a low-cost and simple extraction approach via dehydration, immersion for 2×24 hours in ethanol, and followed by filtration. The optical properties of the dyes in UV and visible light range were observed using a UV-Vis spectrophotometer in the wavelength of 400-700 nm. The absorption behaviour showed dominant peaks at different wavelengths for each group. Potentially, to do a combination of dyes (co-sensitization: using more than a dye with different absorption spectra to achieve a panchromatic response) to widen the wavelength absorption for dye-sensitized solar cell (DSSC) applications.

An unmanned aircraft (UAV) is an aircraft that does not require a crew on board in its operation. This type of aircraft is widely used as a remote monitoring tool such as monitoring disaster sites, monitoring plantation areas, monitoring forests to monitoring enemy areas carried out by the military. For this reason, a study of the adhesive strength required in the connection of unmanned aircraft is needed, such as ribs, spars, skins. From the results of this study, it was found that the mechanical strength of epoxy adhesives depends on several factors such as manufacturer, epoxy content, and operating temperature. The hypothesis of the strength of the epoxy experiment results used by Pustekbang LAPAN ranged from 2,400.4 + 190.6 to 9,664.2 + 1,769.6 psi at room temperature.
