This article examines the reason why Indonesian Javanese are using their traditional medicine jamu. Tracing the cultural logic of Javanese, this study observes the space and the process in which the demand on jamu is culturally constructed. In order to address this, the article focuses on Javanese family and their royal court, the spaces where jamu originated from and has been used. Then, the discussion proceeds to identify jamu as a medium to construct rukun(harmony) and tentram(peace), as well as to express and ensure Javanese cosmology. Along with the research, the article argues that: 1) jamu is an embodiment of Javanese local knowledge system into which Javanese consciousness, notions, knowledge, and techniques integrate; 2) the health achieved by using jamu is what Javanese call tentram, which encompasses physical, mental, spiritual and social dimensions of health; 3) the health of tentram has the value of a resource that becomes the foundation to build a good, prosperous society.

Cyprinids are popular species for aquaculture worldwide, with Asia being a significant contributor to their production. In Korea, common carp (Cyprinus carpio), koi carp (Cyprinus rubrofuscus), and goldfish (Carassius auratus) are cultivated domestically and imported for ornamental or human consumption purposes. Among the viruses that infect cyprinids, cyprinid herpesvirus-2 (CyHV-2), koi herpesvirus (KHV, also known as cyprinid herpesvirus-3), and carp edema virus (CEV) are of particular concern as they cause substantial economic losses to the aquaculture industry. In this study, we investigated these viruses in both of domestic and imported cyprinids. Our results revealed that CyHV-2 was only detected in imported goldfish from Thailand. To further investigate the genetic characteristics of them, the marker A region was analyzed. Despite belonging to the same cluster with isolates from China, France, Poland, and Israel, CyHV-2 detected in this study showed distinct differences in their repetitive sequence sizes. Furthermore, two different forms of KHV/CEV coinfection were identified from domestic koi carp, both of which exhibited typical symptoms. Phylogenetic analysis showed that one KHV isolate (ScKc-2105-K) was of the Asian type and closely related to isolates from Japan, Indonesia, Belgium, Taiwan, and China. Two CEV isolates (ScKc-2105-CE and GhKc-2207-CE) be- longed to the IIa type and showed high similarity with isolates from the USA, France, and Korea. Notably, koi carp injected with cultured KHV (ScKc-2105-K) showed 78.0% cumulative mortality within 14 days post-injection (dpi). Our findings support the importance of regular surveillance of viral diseases in cyprinids.

Archipeligiality, a concept continuously being developed by the scholar, is one that attempts to articulate the Filipino sense of place as discoursed in/through its literatures. As a country composed of 7,107 islands, the very fragmentation and division of the country, as well as its multiculturality and multilinguality, have become the very means by which Filipino writers have "imagined" so to speak-that is, also, constructed, into a singular, united frame-the "nation." This, the author supposes, is an important aspect to explore when it comes to discoursing the larger Southeast Asian imagination, or poetic, as similar situations (i.e. Indonesia, Malaysia, and Singapore), may soon compel for a comparative critico-literary perspective. This paper continues this exploratory "geoliterary" discourse by looking at a Filipino canonical work in English by Cirilo F. Bautista, the epic The Trilogy of Saint Lazarus, the title of which already signals a geographic allusion to the first map-name granted by the Spanish colonizer to the Philippines in the region, and consequently the first signification of the country's subjected existence in the colonial imagination. The work, published between 1970 and 1998, is composed of three parts: The Archipelago, Telex Moon, and Sunlight on Broken Stones, which won the 1998 Philippine Independence Centennial Literary Prize. In these epics, notions of Philippine history and situation were discoursed, and Filipino historical figures were engaged in dialogue by the poet/the poet's voice, with the end of locating the place [where history and time had brought it; or its direction or trajectory as a nation, being true to the Filipino maxim of ang di lumingon sa pinanggalingan, di makararating sa paroroonan (the one who does not look back to his origins would not reach his destination)]. of the Philippines not only in the national imagination, but in this paper, in the wider regional consciousness. The paper proposes that the archipelagic concept is an important and unique characteristic of the Southeast Asian situation, and thus, may be a means to explicate the clearly connected landscapes of the region's imagination through literature. This paper focuses on Sunlight on Broken Stones.

문화정체성은 실로 구성적 성격을 지닌 개념으로, 문화정체성의 구성은 상황 (그리고 역사)과 상념 사이에서 발생하는 역동적인 상호작용의 결과에서 비롯된다. "다약인"이라는 개념의 형성 및 구성에 있어서도 서로 다른 다양한 힘이 작용해왔다. 식민 지배기에 탐험가들과 학자들은 서구적 방식으로 "다약인"의 구성을 구체화시켰고, 이것은 해방 이후 인도네시아 국가의 향방에 순차적으로 영향을 끼쳤다. 다약인 정체성의 구성과 그 동인에 관한 논의는 머리사냥, 긴 형태의 가옥들, 종교 등과 같이 다약인을 그려내는 특정한 이미지에 다만 집중하고, 다약을 그려내는 이러한 이미지들이 오늘날 다약인 정체성과 어떠한 연관성을 지니는가에 관한 논의이다. 과거 머리사냥 풍습에 관해서도 다약인에게 있어서 머리사냥의 의미와 관례를 충분히 설명할 수 있는 분석이 현재 전무하다. 다약인 사회의 또 다른 주요 특징은 독특한 주거양식에서 찾을 수 있다. 주거양식은 대부분의 문헌에서 추정해온 것처럼 독특한 것이 아니라 오늘날에 이르기까지 다약인은 껜야인처럼 종종 연립가옥(라민)을 그들의 중심문화로 여긴다. 깔리만딴 동부에 위치한 롱메카에서 문화와 청년축제가 개최되었는데 이 축제의 전체 진행은 자문화의 재건과 밀접하게 연관되어있다. 2006년에 끄라얀에서 개최된 이와 유사한 한 문화축제는 페뭉 에라우 펜제라니(Pemung Erau Pengerani)라고 불린다. 종교 역시 다약인의 인류학적 설명에 있어서 주요 특징으로, 다약인은 보르네오에 거주하는 비(非)무슬림교도들로 정의된다. 과거에는 거의 대부분의 사람들이 정령신앙을 숭배했으나, 다약인들 사이에서 기독교로의 대규모 개종이 일어나면서 다약인은 기독교도와 일반적으로 동일시되었다. 깔리만딴 지역의 무슬림은 다약인이 될 수 없다는 게 일반적인 생각이다. 실로 다약인이 된다는 것은 수많은 힘들의 집합체로부터 그 구성이 이루어진다는 것을 의미한다.

Resistance to anti-tuberculosis drugs, especially ethambutol (EMB), has been widely reported worldwide. EMB resistance is caused by mutations in the embB gene, which encodes the arabinosyl transferase enzyme. This study aimed to detect mutations in the embB gene of Mycobacterium tuberculosis from Papua and to evaluate their impact on the effectiveness of EMB. We analyzed 20 samples of M. tuberculosis culture that had undergone whole-genome sequencing, of which 19 samples were of sufficient quality for further bioinformatics analysis. Mutation analysis was performed using TBProfiler, which identified M306L, M306V, D1024N, and E378A mutations. In sample TB035, the M306L mutation was present along with E378A. The binding affinity of EMB to arabinosyl transferase was calculated using AutoDock Vina. The molecular docking results revealed that all mutants demonstrated an increased binding affinity to EMB compared to the native protein (-0.948 kcal/mol). The presence of the M306L mutation, when coexisting with E378A, resulted in a slight increase in binding affinity compared to the M306L mutation alone. The molecular dynamics simulation results indicated that the M306L, M306L + E378A, M306V, and E378A mutants decreased protein stability. Conversely, the D1024N mutant exhibited stability comparable to the native protein. In conclusion, this study suggests that the M306L, M306L + E378A, M306V, and E378A mutations may contribute to EMB resistance, while the D1024N mutation may be consistent with continued susceptibility to EMB.

Liver cancer is the fourth leading cause of death worldwide. Well-known risk factors include hepatitis B virus and hepatitis C virus, along with exposure to aflatoxins, excessive alcohol consumption, obesity, and type 2 diabetes. Genomic variants play a crucial role in mediating the associations between these risk factors and liver cancer. However, the specific variants involved in this process remain under-explored. This study utilized a bioinformatics approach to identify genetic variants associated with liver cancer from various continents. Single-nucleotide polymorphisms associated with liver cancer were retrieved from the genome-wide association studies catalog. Prioritization was then performed using functional annotation with HaploReg v4.1 and the Ensembl database. The prevalence and allele frequencies of each variant were evaluated using Pearson correlation coefficients. Two variants, rs2294915 and rs2896019, encoded by the PNPLA3 gene, were found to be highly expressed in the liver tissue, as well as in the skin, cell-cultured fibroblasts, and adipose-subcutaneous tissue, all of which contribute to the risk of liver cancer. We further found that these two SNPs (rs2294915 and rs2896019) were positively correlated with the prevalence rate. Positive associations with the prevalence rate were more frequent in East Asian and African populations. We highlight the utility of this population-specific PNPLA3 genetic variant for genetic association studies and for the early prognosis and treatment of liver cancer. This study highlights the potential of integrating genomic databases with bioinformatic analysis to identify genetic variations involved in the pathogenesis of liver cancer. The genetic variants investigated in this study are likely to predispose to liver cancer and could affect its progression and aggressiveness. We recommend future research prioritizing the validation of these variations in clinical settings.

The fingerprint image quality relies on the clearness of separated ridges by valleys and the uniformity of the separation. The condition of skin still dominate the overall quality of the fingerprint. However, the identification performance of such system is very sensitive to the quality of the captured fingerprint image. Fingerprint image quality analysis and enhancement are useful in improving the performance of fingerprint identification systems. A fuzzy technique is introduced in this paper for both fingerprint image quality analysis and enhancement. First, the quality analysis is performed by extracting four features from a fingerprint image which are the local clarity score (LCS), global clarity score (GCS), ridge_valley thickness ratio (RVTR), and the Global Contrast Factor (GCF). A fuzzy logic technique that uses Mamdani fuzzy rule model is designed. The fuzzy inference system is able to analyse and determinate the fingerprint image type (oily, dry or neutral) based on the extracted feature values and the fuzzy inference rules. The percentages of the test fuzzy inference system for each type is as follow: For dry fingerprint the percentage is 81.33, for oily the percentage is 54.75, and for neutral the percentage is 68.48. Secondly, a fuzzy morphology is applied to enhance the dry and oily fingerprint images. The fuzzy morphology method improves the quality of a fingerprint image, thus improving the performance of the fingerprint identification system significantly. All experimental work which was done for both quality analysis and image enhancement was done using the DB_ITS_2009 database which is a private database collected by the department of electrical engineering, institute of technology Sepuluh Nopember Surabaya, Indonesia. The performance evaluation was done using the Feature Similarity index (FSIM). Where the FSIM is an image quality assessment (IQA) metric, which uses computational models to measure the image quality consistently with subjective evaluations. The new proposed system outperformed the classical system by 900% for the dry fingerprint images and 14% for the oily fingerprint images.

Betung bamboo (Dendrocalamus asper) is used as a building and handicraft material in Indonesia; however, bamboo needs to be dried to increase its stability. This study aimed to evaluate the efficiency of drying bamboo using solar energy and different drying oven designs. The betung bamboo pieces were dried using a direct solar dryer (direct drying) and an indirect solar dryer (indirect drying) and then the decrease in levels that occurred based on the relative humidity (RH) and temperature values achieved in the two dryers were compared. The highest average temperature in the direct indirect drying oven compartment was 60.1 ± 13.1℃ with 19.9 ± 16.4% RH and 60.2 ± 11.9℃ with 19.5 ± 15.5% RH, respectively. The drying defect in indirect drying was lower than that in direct drying, and indirect drying had a 61.7% greater average water loss than direct drying with significant difference (95%, analysis of variance) based on water loss/compartment volume parameters. Thus, the solar drying oven can be used to air-dry bamboo (14%) for 7 d from an initial moisture content of 70%-80% in bamboo strips. The results of this research can be used for small-scale bamboo processing industries that have limited use of electrical energy with quite good results.

Swietenia mahagoni is one of the commercial timbers in Indonesia. Mahogany heartwood is an important characteristic as it relates to the natural durability and aesthetics of the wood. Lipophilic extractives are known to be involved in the heartwood formation process. Therefore, this study aims to determine the lipophilic compounds associated with heartwood formation. The n-hexane extract from sapwood and heartwood samples (1 to 5 years) was analyzed by gas chromatography-mass spectrometry. The results showed that the content of n-hexane extract ranged from 0.76% to 2.45% based on dry wood. The main group of compounds identified in the lipophilic fraction consisted of sterols (β-sitosterol, stigmasterol, campasterol, and cyclolaudenol), fatty acids (palmitic, oleic, linoleic, and stearic acid), and hydrocarbons (pentadecane, 1-octadecane, hexadecane, cyclotetracosane, cycloeicosane, and cyclooctacosane) after heartwood formation. In addition, the hydrocarbon fraction was the largest, followed by sterols, fatty acids, and 1-heneicosanol. In the radial variation, the distribution of fatty acids was greater in the sapwood than in the heartwood (4-year-old). However, the reverse pattern was found at the age of 5 years. The lipophilic fraction was generally more abundant in the heartwood compared to the sapwood, especially at 5 years of age, with much higher levels than when the heartwood was forming (4 years). These findings show that when the heartwood formation begins, the lipid composition was not fully metabolized at the beginning of heartwood formation compared to 5-year-old trees.
