Abstract

Growth response of two C3 (wheat and kale) and two C4 species (Echinochloa crusgallii and Amaranthus caudatus) were analyzed in response to drought stress under different CO2 concentrations, i.e. ambient (350 ppm) and double ambient (700 ppm).  Drought was given by withholding water for several days until the plants were wilted.  Drought stress reduced relative water content (RWC), water potential (Yw), osmotic potential (Ys), net photosynthesis (Pn) and plant growth of all species.  During moderate drought Pn of C3 species decreased considerably, while that of C4 species was still sustained, suggesting that C4 cycle is important to sustain Pn during the beginning of the drought.  Doubled [CO2] enhanced growth of all species indicated by increase of plant height and leaf area, but the growth of C3 species was higher than that of C4 one.  Increase of growth due to high [CO2] was associated with an increase of Pn in C3 species but not in C4 species.  High [CO2] caused C4 species had RWC, Yw and Ys higher than C3 species during drought stress.  Increase of growth in C4 species may be associated by an increase of plant water status due to high [CO2].

Abstract

Penelitian ini menganalisis makna simbol komunikasi dalam banner Politik Jalan Ninja oleh Patai Solidaritas Indonesia (PSI). Teori yang digunakan pada penelitian adalah teori semiotika struktural Roland Barthes.  Metode analisis semiotika struktural Roland Barthes digunakan untuk mengungkap tiga tingkatan makna pada tanda, yaitu denotasi, konotasi, dan mitos sebagai pesan tersurat dan tersirat pada banner. Hasil penelitian mengungkapkan bahwa makna denotasi pada banner Politik Jalan Ninja PSI adalah ajakan berpolitik ala PSI dengan sebutan jalan ninja. Lalu, makna konotasi pada banner Politik Jalan Ninja PSI adalah bayangan pemikiran, bayangan karakter, dan bayangan privilege dari Jokowi terhadap Kaesang Pangarep dan PSI sedang mencari anggota sebanyak-banyaknya sesuai pandangan PSI. Lalu, makna mitos pada banner Politik Jalan Ninja PSI adalah politik tirani yang telah dibangun secara diam-diam, terstruktur, dan terencana dalam waktu yang lama dan ideologi tatanan sosialisme.

Abstract

Rice cv. Hawara Bunar is a local rice cultivar tolerant to aluminum (Al) and drought stress. However, the cultivar has inferior characteristics, such as a tall habitus and a small number of tillers, making the cultivar agronomically unattractive. Many genes control plant height and tiller number; one is the TAD1 gene. Analysis of gene expression in two contrasting rice cultivars for both characters is a prerequisite for selecting certain genes for gene editing targets. This study aimed to analyze the gene expression of the TAD1 in rice cv. IR64 and Hawara Bunar, and to construct a phylogenetic tree of genes that regulate rice plant height and tiller number. Gene expression analysis was conducted using the qRT-PCR technique, while the phylogenetic tree was constructed based on the Neighbor-Joining method using PAUP4 software. The results showed TAD1 gene expression in the tillering phase of rice cv. Hawara Bunar is higher than the cv. IR64. The gene expression level in both cultivars corresponds to the plant height and tiller number characters in both rice cultivars. Phylogenetic analysis showed that the TAD1 gene clustered with genes that cause the rice to have a tall habitus with few tillers. The results of a transcriptome meta-analysis reinforced the phylogenetic tree, which shows that the TAD1 gene was found in a group of downregulated genes based on the volcano plots. Therefore, the TAD1 gene can be selected as a target gene for editing in rice cv. Hawara Bunar to obtain superior characters.

Abstract

Hypertension is a widespread health problem and is often called a "silent killer" because it often has no warning signs or symptoms, and many people don't realize they have it. The purpose of this study is to determine the effectiveness of alkahil point cupping therapy and acupuncture therapy on blood pressure in hypertensive patients in Karangbong Village, Pajarakan District, Probolinggo Regency. The method in this study is Pre-Experiment, with a Two-group pre-post test design, the sample in this study is patients with hypertension totaling 36 patients who were taken using the purposive sampling instrument technique which was used were cupping devices, acupuncture tools, tension meters and observation sheets. Furthermore, it was analyzed using the Paired t-test, the Wilxocon test, the Independent t-test, and the Mann-Whitney test. The results of the study showed that before the alkahil point cupping therapy was carried out, an average value of 149/102 mmHg was obtained, and the average value before acupuncture therapy was 149/99 mmHg. After alkahil point cupping therapy , an average value of 139/92 mmHg was obtained and after acupuncture therapy was 134/90 mmHg. It is known that the average value of the pre-post sistole difference of alkahil point cupping therapy is 10.33, and the average value of the pre-post difference of acupuncture therapy is 15.00 with a pV of 0.000 which means < 0.05. Meanwhile, the average value of the pre-post diastole difference in alkahil point cupping therapy was 19.61 and acupuncture therapy was 17.39 with a pV > 0.05. It can be concluded that the average value of the difference in pre-post sistole of acupuncture therapy is more effective than alkalil point cupping therapy in reducing blood pressure in hypertensive patients Alkahil point cupping therapy and acupuncture therapy can be traditional alternative treatments that can be done routinely for the hypertension healing process by doing acupuncture therapy.

Abstract

This research reviews attentional distraction factors in mobile phone-based language learning and proposes the Interactive Model of Attentional Distraction Management in learning as a new theoretical framework. Distractions from multitasking, notifications and social media apps were shown to reduce attention as well as memory function, hindering important cognitive processes in language acquisition. Individual factors such as age, gender and experience also affect the ability to manage distractions, which reinforces the urgency of adaptive attentional management. This new theoretical framework offers an interactive and personalised solution with three main components: cognitive, psychological and social environmental elements. Mobile phone-based applications can adjust learning settings in real-time, providing better user control over distractions. This model is expected to improve learners' focus, maintain attention, and support the effectiveness of technology-based language learning.
