This study aims to describe the morphological forms of slang, explain the processes of its formation, and analyze its frequency and distribution in the TikTok content of the account @shadirafirdausi. The study is motivated by the rapid development of slang on social media, particularly TikTok, as a platform where young people express identity, creativity, and social interaction. A qualitative descriptive method was employed using documentation techniques on three TikTok videos, including captions and comments with the highest numbers of views and likes during June–August 2025. Data were analyzed using the interactive model of Miles and Huberman, consisting of data reduction, data display, and conclusion drawing. The findings identified 36 slang words and phrases classified into four morphological processes: phonological modification (30.6%), shortening (30.6%), affixation (25.0%), and compounding with foreign element adoption (13.9%). Phonological modification and shortening were the dominant processes, while affixation and English borrowings further enriched the language forms. These findings demonstrate that slang in @shadirafirdausi’s TikTok content is formed through creative, productive, and adaptive morphological processes that reflect the preference of young speakers for concise, expressive, and easily understood language in digital communication.

Anemia during pregnancy remains a common health problem and may lead to adverse outcomes for both mother and fetus. Hemoglobin and erythrocyte indices examination are important to identify anemia and describe erythrocyte morphology in pregnant women. This study aimed to describe hemoglobin levels and erythrocyte indices among anemic pregnant women at Sentosa Maternity Hospital. This research used a descriptive design with secondary data obtained from hematological examination results of pregnant women who underwent laboratory testing at Sentosa Maternity Hospital from January to December 2023. Data were analyzed descriptively and presented in frequency distribution tables. The results showed that out of 58 pregnant women undergoing hematological examination, 28 women (48%) were anemic with a mean hemoglobin level of 10.2 g/dL, while 30 women (52%) had normal hemoglobin levels with a mean of 12.8 g/dL. Based on erythrocyte indices, most anemic pregnant women had microcytic hypochromic anemia, accounting for 19 women (67%) with mean MCV of 72.3 fL, MCH of 29.8 pg, and MCHC of 33.9 g/dL, whereas 9 women (33%) had normocytic normochromic anemia with mean MCV of 83.4 fL, MCH of 29.6 pg, and MCHC of 33.4 g/dL. It can be concluded that nearly half of the examined pregnant women experienced anemia, with microcytic hypochromic anemia being the most dominant type.

Based on the current existing conditions, Perumnas IV frequently experiences challenges in both the maintenance of its facilities and infrastructure and the perception of its residents. This study aims to: 1) Determine the morphology and typology of the Perumnas IV Padang Bulan area, 2) Determine the level of feasibility of the infrastructure based on SNI 03-1733-2004, and 3) Determine public perception of the infrastructure based on existing conditions and research analysis results. The research method used by the author in this study is a mixed method using an Explanatory Sequential Design approach and a comparative approach. The difference in feasibility percentages between SNI and public perceptions explains that residents have become accustomed to living with the existing facilities and infrastructure, so that the suitability between existing conditions and applicable technical requirements is not a problem in daily life.

The development and performance of high-strength, environmentally friendly, and renewable nunang fiber (Cordia dichotoma)-reinforced polyester composites continue to be refined to achieve optimal performance. This study characterizes the key properties of nunang fiber-reinforced polyester composites with carbon powder fillers. The polyester composites were fabricated using a hot-press method with a nunang fiber volume fraction of 20% (by weight) and varying carbon powder content from 0–10% (by weight). The results of the investigation show that the tensile and bending strengths of the composites increase with increasing carbon powder content up to 2.5%. However, adding carbon powder filler up to 10% to the polyester–nunang fiber composites reduces their tensile and bending strengths. A different trend is observed for the impact toughness of the composites, which increases up to a carbon powder content of 5% and decreases when the carbon powder content reaches 10%. This phenomenon is attributed to the ability to form an optimal fiber-matrix interface between the nunang fibers and the polyester–carbon powder matrix. SEM morphological observations confirmed fiber pull-out failure and matrix failure due to the high stiffness caused by the presence of the carbon powder filler.

Rebonding is a chemical hair straightening procedure widely popular in Indonesia, involving two-stage redox reactions on keratin disulfide bonds using ammonium thioglycolate and hydrogen peroxide. Although it provides effective hair-straightening results, rebonding potentially causes significant damage to the hair cuticle structure. This study aimed to analyze the morphological changes of hair surface before and after rebonding treatment through a descriptive comparative case study approach using Scanning Electron Microscopy (SEM). The samples consisted of one strand of healthy, chemically untreated hair (control) and one strand of post-rebonding hair that both obtained from a female. Samples were prepared using gold-sputter coating prior to SEM observation. Representative SEM images from each sample were then qualitatively compared based on cuticle morphology parameters. The results showed clear morphological differences between the two samples: the control hair displayed tightly arranged and orderly cuticle scales with a smooth surface, while the post-rebonding hair showed surface erosion and the presence of cracks in multiple areas of the cuticle. These findings confirm that rebonding procedures cause visible and characterizable morphological cuticle damage as identified through SEM, providing a scientific basis for developing more protective post-rebonding hair care products.

Travertine is a non-marine carbonate rock precipitated from calcium- and bicarbonate-rich waters, commonly associated with hot springs, streams, and lakes in tectonically active regions. This study presents a systematic literature review of travertine deposit characteristics, encompassing mineralogical composition, geochemical signatures, petrographic textures, morphological types, isotopic properties, biotic–abiotic controls on formation, early diagenesis, and petrophysical implications. The synthesis indicates that travertine is predominantly composed of calcite, with aragonite forming under conditions of elevated temperature, high Mg/Ca ratios, and rapid CO₂ degassing. Travertines display exceptional textural diversity, ranging from abiotic crystalline crusts to microbially mediated fabrics such as shrub, peloidal, and stromatolitic structures. Major morphologies include fissure ridges, mounds, terraces, cascades, and slopes, strongly governed by tectonic setting, topography, hydrology, and substrate geology. Stable isotopes (δ¹³C and δ¹⁸O), strontium isotopes, trace elements, and REE patterns effectively constrain fluid provenance and distinguish thermogene from meteogene travertines. Microbial activity plays a crucial role in biomineralization, influencing precipitation rates, crystal morphology, and lamination patterns. Early diagenetic processes occurring during active deposition may significantly modify primary fabrics and geochemical signals. Travertine petrophysical properties exhibit distinctive porosity–velocity relationships, making them valuable analogues for subsurface carbonate reservoirs. This review highlights that travertines record complex interactions among physical, chemical, biological, and geological processes and hold significant value for paleoenvironmental reconstruction and carbonate reservoir studies.

Consumption of ethylene glycol–containing drugs can cause liver damage. This study aimed to evaluate the hepatoprotective potential of Moringa leaf extract (Moringa oleifera L.) on AST and ALT levels, liver morphology, hepatosomatic index, and liver histology in ethylene glycol–induced white rats (Rattus norvegicus L.). A Completely Randomized Design (CRD) was used with 20 male rats divided into five groups: normal control, ethylene glycol control, and three treatment groups (150, 300, and 450 mg/kg BW). Ethylene glycol was administered for 30 days, while the extract was given for 20 days. Blood samples were collected on day 31. Data were analyzed using One Way ANOVA and Duncan’s test. The results showed significant hepatoprotective effects (P = 0.000). AST and ALT levels in the treatment groups differed significantly from the normal control. Liver morphological changes were observed in both control and treatment groups. The hepatosomatic index, number of normal hepatocytes, and central vein diameter also showed significant differences. In conclusion, Moringa leaf extract demonstrates hepatoprotective potential by reducing AST and ALT levels, improving liver morphology, increasing normal hepatocytes, and decreasing central vein diameter, with the optimal dose at 450 mg/kg BW

Background: Autoimmune Hemolytic Anemia (AIHA) is a rare immunological condition that causes the destruction of red blood cells through autoantibodies. Case Presentation: This report discusses the case of a 38-year-old woman who presented with complaints of weakness and acute dizziness at RedaBolo, with a history of recurrent anemia over the past six months. Physical examination revealed clear signs of hemolysis, including icteric sclera and splenomegaly. Laboratory findings confirmed severe anemia (Hb 5.0 g/dL) with varied peripheral blood cell morphology (spherocytes, schistocytes, and teardrop cells). The diagnosis was supported by a positive Coombs test and hyperbilirubinemia.  Management: The therapeutic strategy focused on hemodynamic stabilization through transfusion of 4 units of packed red blood cells (PRC), immunosuppression with methylprednisolone 125 mg/day, and gastric protection. Conclusion: These interventions yielded satisfactory results, with the patient achieving significant clinical improvement and a hemoglobin level of 9.5 g/dL by the fourth day of treatment.

This study investigates the use of derivational morphemes in David Goggins' motivational speech, “12 Minutes to Change Your Life,” featured on Huberman's podcast. Derivational morphemes, which create new words and alter grammatical categories, are essential in understanding language development and communication. Despite extensive research on derivational morphemes in various texts, there is limited analysis of their usage in motivational speeches. This study addresses this gap by analyzing Goggins' speech, focusing on identifying and classifying derivational morphemes. Using qualitative methods, the speech was transcribed, and words containing derivational morphemes were analyzed based on the theories of Fromkin, Rodman, and Hyams (2011). The findings reveal 23 instances of derivational morphemes, divided into class-changing and class-maintaining categories. Notable transformations include adjectives to adverbs, verbs to nouns, and adjectives to nouns, with the most frequent being adjectives to adverbs. The study provides insights into the function and impact of derivational morphemes in spoken motivational content, contributing to the broader understanding of morphology in language use.

Inflectional morphemes are of great importance in linguistic analysis, especially when applied to speech delivered in various contexts. We explore the complexity of inflectional morphemes through an analysis of Linda McMahon’s Speech script titled “Our Department’s Final Mission.” Inflectional morphemes are also known as grammatical morphemes, as their primary function is to provide grammatical information about a word without altering its core meaning or lexical category. These inflectional morphemes include possessive morphemes (-‘s/s’), plural morphemes (-s/es), third-person singular present morphemes (-s), past morphemes(-d/ed), present/progressive particles (-ing), past participle (-en), comparative particles (-er), and superlative particles (-est). Therefore, this study focuses on understanding the types of inflectional morphemes used in Linda McMahon’s speech script. The main theory of inflectional morphemes is based on an understanding of grammatical function, affixation processes, and categories in the language system. The researcher identified 7 categories of inflectional morphemes. The result showed that 99 inflectional morphemes were found in Linda McMahon’s speech script. There were 46 plural morphemes (-s), 26 present/progressive particle morphemes (-ing), 19 past tense morphemes (-ed), 4 possessive morphemes (-‘s/s’), 2 third-person singular present morphemes (-s),1 comparative morpheme (-er), and 1 superlative morpheme (-est). It can be conclude that the most dominant category in the analysis is the plural morpheme (-s) and the least dominant is the comparative (-er) and superlative (-est) morpheme. Its is hoped that this study can provide solutions in determining the types of inflectional morphemes in a speech script.

This study discusses reduplication as one of the important morphological processes in the Indonesian language. Reduplication plays a role in the formation of words and serves to express various grammatical meanings, such as plural, frequency, intensity, and continuity of an event. The purpose of this study is to describe the types of reduplication and the classes of words produced through this process. The research data is in the form of duplicated words, including materials, people, years, destruction, many times, and shouting. The method used is qualitative descriptive with analysis techniques in the form of classification based on the type of reduplication, namely intact reduplication, partial reduplication, reduplication with adjustment, and altered reduplication of sounds. The results of the study show that reduplication in Indonesian can form various classes of words, such as nouns, verbs, adjectives, and adverbs, with different grammatical functions according to the context of their use. These findings confirm that reduplication not only serves as a repetition of forms, but also has a significant semantic and syntactic role in the structure of language. This research is expected to make a theoretical contribution to the study of Indonesian morphology and become a reference for future linguistic research, especially in understanding the dynamics of word formation and meanings produced through the process of reduplication.

This research is motivated by the importance of studying pronouns in literary works because pronouns play a role in building cohesion and the meaning of stories. This research aims to describe the form and function of pronouns in the short stories Thank You for Today, Sad Stories on Sunday 4.0, and Uncle Gordi by Yoga Zen in the digital media of Ruang Sastra. This study uses a qualitative descriptive method with a morphological approach. The data source was in the form of three short stories by Yoga Zen, while the research data was in the form of words containing pronouns. The data collection technique is carried out through reading, listening, and recording techniques. The results of the study showed the existence of persona pronouns, pointer pronouns, and questioner pronouns. Persona pronouns include first, second, and third personas in the singular or plural. Pointer pronouns include general pointers, places, and concerns, while questioner pronouns include questioners people, causes, places, and circumstances. The use of pronouns in the three short stories serves to build story cohesion, strengthen the storytelling point of view, and describe the psychological condition of the characters.

This study examines compounding in exposition texts written by Grade XI students of SMA Swasta Anastasia.

Students of vocational high schools are required to write an internship report as a form of accountability for completing their industrial training. However, various language errors are still found in students’ PKL reports. This study aims to describe and analyze morphological errors in the PKL reports of vocational high school students majoring in Electronics Engineering. The study employed a descriptive qualitative approach using document analysis. A total of 223 PKL reports were written by all students of SMK Negeri 3 Yogyakarta in 2025. The research data consisted of 25 PKL reports from students of the Electronics Engineering major selected through purposive sampling. Data analysis was carried out through the stages of identification, classification, description, quantification, and interpretation of morphological errors, with data validity ensured through theoretical triangulation. The results show that 286 morphological errors were identified, consisting of prefix errors (96), suffix errors (52), confix errors (41), reduplication errors (28), compound word errors (34), and base-form errors (35). Prefix errors were the most dominant type, accounting for 33.6% of all errors. These findings indicate that students still experience difficulties in applying affixation rules and forming standard words in formal written language. Such errors are influenced by interference from spoken language and the technical language used in the workplace. This study highlights the importance of structured and contextual morphology instruction to improve the quality of vocational students’ PKL report writing.

This study aims to analyze the effect of Tungsten Inert Gas (TIG) welding parameter variations on the mechanical and metallurgical properties of AISI 304 austenitic stainless steel, which is widely used in construction and industrial applications due to its excellent corrosion resistance and joint strength. The research focuses on identifying the optimal welding current to minimize welding defects and enhance joint structural integrity. Welding current was varied at three levels, namely 100 A, 125 A, and 135 A, while other parameters such as welding speed, argon shielding gas flow rate, and electrode type were kept constant. Mechanical properties were evaluated through Micro-Vickers hardness testing conducted in the weld metal, Heat Affected Zone (HAZ), and base metal, as well as tensile testing to determine ultimate tensile strength and elongation. In addition, non-destructive testing using the dye penetrant method was performed to detect surface welding discontinuities. Metallographic analysis was carried out using optical microscopy following an etching process to observe grain morphology, grain size, and the formation of microstructural phases. The results are expected to demonstrate a correlation between increased heat input due to higher welding current and changes in mechanical properties and microstructure, particularly in the HAZ. This study provides practical guidance for determining optimal TIG welding parameters for AISI 304 to achieve high tensile strength, homogeneous hardness distribution, and a stable microstructure resistant to intergranular corrosion.

Abbreviation is a common linguistic strategy used to achieve efficiency and clarity in modern communication. This study examines the abbreviation systems of English and Indonesian through a contrastive linguistic approach, focusing on morphological patterns, phonological constraints, and usage conventions. Employing a qualitative descriptive design, the data were collected from established linguistic references and analyzed using classical contrastive analysis principles. The findings reveal that English abbreviation formation is structurally flexible, allowing both pronounceable acronyms and non-pronounceable initialisms, often maintaining complex consonant clusters and orthographic capitalization. In contrast, Indonesian abbreviation formation is strongly influenced by phonological preferences, particularly ease of pronunciation and conformity to open syllable structures, resulting in forms that closely resemble ordinary lexical items. These structural differences suggest potential sources of negative transfer for language learners and challenges in translation practices. The study concludes that abbreviation systems are shaped not only by linguistic rules but also by sociocultural and communicative needs. Understanding these contrasts is essential for language teaching, translation, and further comparative linguistic research.

Domestic wastewater management in densely populated areas remains challenging because conventional concrete/steel septic tanks can crack or corrode, increasing leakage risk and potentially degrading groundwater quality. This study aims to compare conventional septic tanks with Fiberglass Reinforced Plastic (FRP) septic tanks and to develop an FRP septic tank concept that improves durability, installation practicality, and treatment performance for residential use. A qualitative comparative approach was applied through purposive selection of households/public facilities, in-depth interviews (users, technicians, manufacturers), direct observations of tank conditions and maintenance, and documentation; findings were reduced, categorized (material, efficiency, cost, environmental impact), and thematically interpreted. The study produced an FRP septic tank design concept developed using an Objective Tree, Function Structure, and Morphology Chart, resulting in planning criteria and conceptual drawings. The FRP concept emphasizes lightweight strength, corrosion/chemical resistance, and shape stability under soil loads, while incorporating multi-partition internal processing and media (bioballs) to support staged treatment using gravity flow. The proposed design can reduce leakage risk, simplify installation and maintenance, extend service life, and support more sustainable domestic waste management in space-limited urban neighborhoods. The novelty lies in a residential FRP septic tank concept that integrates three partitions, bioballs, and gravity-based flow without relying on pumps/motors, supported by a structured product-engineering design framework.

This study is entitled Nahwu and Shorof as Sciences in the Ontological Perspective within the Realm of Philosophy. The purpose of this research is to examine the essence of nahwu and shorof not merely as technical tools for understanding the Arabic language, but also as scientific entities that possess ontological dimensions in philosophy. Nahwu is understood as the science that regulates the arrangement of words within sentences, while shorof functions to form and transform words according to specific patterns. From an ontological perspective, both are not simply linguistic instruments, but rather representations of the structure and form of linguistic reality that reflect the orderliness of human thought. The analysis demonstrates that nahwu and shorof play a fundamental role in preserving the integrity of meaning in Arabic texts, while also serving as a means to comprehend the essence of language as a living and dynamic entity. Thus, nahwu and shorof can be regarded not only as practical sciences in language learning, but also as philosophical disciplines within the ontology of knowledge, revealing the essence of form and structure of language in relation to human and societal reality.
