Abstract

Xanthan gum is an extracellular polysaccharide produced by a pure culture of Xanthomonas campestris through the fermentation process of carbohydrate sources in controlled conditions. These conditions must be carefully evaluated to obtain an optimal combination between yield and quality of the gum, and also production costs. The issue of this review is to provide a consolidated source of information on studies about xanthan gum production, alternative carbon sources from biomass substrates, effective variables on optimization production, characteristics, applications, and regulations status of xanthan gum. Lastly, the market potential is also discussed in this review.

Abstract

This study explores the assumption that Pangkalan, situated as a transit area between West Sumatra and Riau, experiences considerable linguistic interaction, potentially leading to lexical variations in the Minangkabau language. The research focuses on identifying and describing lexical differences in the Minangkabau language as used by both older and younger speakers, further distinguishing between those with formal schooling and those without. Data were gathered through observation and elicitation methods, employing a descriptive qualitative approach to capture lexical variations among speakers in Nagari Pangkalan. Analysis involved both referential and translational equivalent methods. Out of 744 lexical concepts analyzed, 216 exhibited variations between older and younger speakers. Additionally, 23 unique lexical differences were noted among young speakers based on their educational background. Notably, 45 lexical items were distinctive to older speakers, whereas 10 were unique to younger speakers. Contrary to the initial hypothesis that Pangkalan's role as a transit area would heavily influence lexical variation, the study found that educational factors played a more significant role in shaping the observed lexical differences.

Abstract

This research aims to explain the form, semantic components, and distinguishing features of synonymous adjectives in the Rejang language, based on a study in Talang Boseng Village, Pondok Kelapa District, Central Bengkulu. A descriptive research design with a qualitative approach was employed. Data collection involved interview and observation methods. For data analysis, translational equivalence, distributional, and componential analysis methods were utilized. The distributional method was applied using substitution and expansion techniques. The findings reveal two forms of synonymous adjectives: word-to-word and word-to-phrase. The semantic components of these synonymous adjectives can be categorized into four groups: (1) tending to be similar, (2) tending to be different, (3) exactly the same, and (4) an equal number of similarities and differences. Nine factors differentiating the meanings of these synonymous adjectives were identified: (1) one is more general, (2) more intensive, (3) more emotive, (4) more professional, (5) encompasses acceptance and rejection, (6) more colloquial, (7) local or regional in nature, (8) differences in application, and (9) differences in implication. The distinctiveness of adjectives in the Talang Boseng isolect of the Rejang language is evident in the semantic differences arising from variations in application, which can be further subdivided into temporal and object applications.

Abstract

The traces of the Minangkabau language in Negeri Sembilan are evidence that the Minangkabau people not only migrated to the coastal areas of Sumatra but also to the Malay Peninsula. Despite historical evidence linking the Tanjong Ipoh isolect to Minangkabau, the extent of phonological change in this isolect remains undocumented. This study seeks to bridge this gap by systematically analyzing phonological evolution. This study aims to describe the forms and types of phonological changes observed in the Tanjong Ipoh isolect, located in Kuala Pilah, Negeri Sembilan, Malaysia. Data were collected through observation and interviews. We interviewed three native speakers of the Tanjong Ipoh isolect, selected through purposive sampling based on linguistic competence and community recognition, who participated in this study. Additionally, we also interview various speakers to help validate the data. We documented the data using both note-taking and recording techniques. We conducted the analysis using a top-down approach by identifying Minangkabau protolanguage (PBM) reflexes in the Tanjong Ipoh isolect. The results are that the vowels that have changed in Tanjong Ipoh isolect are *i, *u, *ə, *e, and *a, while PBM consonants that have changed in Tanjong Ipoh isolect are *t, *k, *s, *R, and *l. PBM consonant changes in the Tanjong Ipoh isolect consistently occur in environments where PBM vowels also change. The study concludes that all sound changes observed in the Tanjong Ipoh isolect are conditioned. Among the types of changes, lenition (weakening) is the most prevalent, with additional changes including assimilation, dissimilation, fortition, diphthongization, splitting, merging, and elimination. The findings align with established phonological theories and contribute to understanding language evolution in migrant communities.

Selanjutnya, pada tahap penyajian hasil analisis data, digunakan metode formal dan metode informal. Berdasarkan hasil penelitian yang dilakukan, (1) Variasi leksikal bahasa Minangkabau di Kecamatan Ranah Pesisir ditemukan sebanyak 190 dari 588 daftar pertanyaan yang diajukan. (2) Sebanyak 190 data variasi leksikal tersebut dipetakan dalam bentuk sistem lambang. (3) Hasil penghitungan dialektometri variasi leksikal bahasa Minangkabau yang ditemukan di Kecamatan Ranah Pesisir termasuk ke dalam kategori beda wicara dan tidak ada perbedaan, dengan hasil persentase sebanyak 17,00%“23,12%. Dari hasil persentase tersebut, daerah yang menunjukkan beda wicara karena secara geografis nagari tersebut letaknya terpencil dan rata-rata masyarakat nagari hanya lulusan SD dan SMP, sedangkan persentase daerah yang tidak menunjukkan perbedaan disebabkan oleh jarak masing-masing TP cukup berdekatan sehingga sering terjadi hubungan komunikasi antarmasyarakat. Kata kunci: bahasa Minangkabau, beda wicara, dialektologi, pemetaan, variasi leksikal

Abstract

The objective of this research is to describe the assimilation process in the Toba Batak language, specifically as it is spoken in Pintu Padang Village, located in North Sumatra, Indonesia. Assimilation is a type of sound change that is not the same to become the same or almost the same. This process can occur between segments in a word and between components in compound words. So, it is essential to formalize it by describing the sound features that undergo these changes. The data was gathered through observation and interviews. Listening to Batak Angkola speakers communicate with one another allowed for observations. Simultaneously, interviews were conducted by directly interviewing informants who were chosen based on particular criteria. Three individuals were interviewed using a structured interview format. In addition, a set of unstructured interviews was carried out with several other speakers. For this purpose, a generative phonology approach is used. Data analysis was carried out by the distributional method with the segmenting immediate constituents technique. After that, the distinctive features of the sound are explained. The results of this research show that assimilation took place in nasal consonants [m], [n], and [ŋ], which met the consonants [k], [p], [s], [t], [l], and [c]. The sounds [m], [n], and [ŋ] appear in the forms [p], [t] and [k], respectively. Then, the sound [n] appears in the form [l] and [c] when it meets the sounds [l] and [c] too. Generally, it can be inferred that sound modifications in the form of assimilation are homorganic.
