Authors: Isda Mayta Novaliza , Salsabilla Melda Jannatul 
Published: November 2023

Tacca chantrieri belongs to the family Taccaceae has black flowers and has a long filiform that looks like a bat. T. chantrieri contains phytochemicals in the form of spritosol saponins used as traditional medicine by the people of China and Thailand. The amount of land clearing, forest exploitation and habitat destruction resulted in a reduction in the number of T. chantrieri, so T. chantrieri was propagated to maintain its sustainability. One way that can be used is the in vitro culture technique, namely callus culture. Callus culture is an early stage of in vitro culture technique where this stage aims to produce and multiply callus cells. The purpose of the study is were to determine the effect of different sucrose concentrations on callus induction from T. chantrieri leaf explants and determine the best sucrose concentrations for callus culture from T. chantrieri leaf explants on Murashige and Skoog (MS) media. This study used a single factor completely randomized design (CRD), namely sucrose concentrations 0 g/l, 10 g/l, 20 g/l, 30 g/l, 40 g/l, 50 g/l with five replications. The results of this study showed that the administrations of sucrose with different concentrations on MS media had an effect on increasing callus induction in Tacca chantrieri leaves. The best sucrose concertations for callus induction of Tacca chantrieri leaves was the addition of 40 g/l sucrose at 20 days after planting, 60 % callus formation percentage, callus formed in the form of compact callus and produce yellow-white callus. Keywords: Tacca chantrieri, sucrose, callus, Murashige and Skoog.

Published: November 2023

Linear alkylbenzene sulfonate (LAS) is the main component of dispersants that function as cleaners of various materials. The increasing use of LAS causes this compound to dominantly pollute coastal waters. Phytoremediation is the most environmentally safe alternative to physical and chemical methods. One of the potential plants as a phytoremediator is Rhyzophora mucronata. This research is an experiment as an application of LAS pollutant control by Rhyzophora Mucronata (R. Mucronata) plants in waters. After acclimatization and preliminary tests, the implementation of LAS phytoremediation tests by R. Mucronata plants in seawater media was carried out at concentrations of A1: 25 mg/L, A2: 100 mg/L, A3: 175 mg/L, A4: 250 mg/L, and A5: 325 mg/L and control (Control without plants) as a simulation of the presence of pollutants in coastal waters. The method used was a completely randomized design (CRD) with one treatment and 3 replications. The reduction of LAS concentration in the test media and its effect on R Mucronata leaf chlorophyll and dissolved oxygen were analyzed at week 2 to week 4. The analysis results showed that LAS compounds could be reduced to 91.48% at week 2 and 97.40% at week 4. Plant Water quality parameters (dissolved oxygen, temperature and pH) were measured daily. Based on the study results, LAS can be reduced by R. Mucronata plants 87-90.4% in week 2 and 95.1-97.4% in week 4. LAS exclusion by plants had a significant impact on the reduction of leaf chlorophyll content until week 4. LAS reduction by R. Mucronata in the media can increase dissolved oxygen content as an indication of improved water quality. R. Mucronata plants can be used as an alternative to control LAS pollution in waters
Nepali ESL/EFL Student Translators' Manipulation of Sentences at the Textual Level
Authors: Adhikari Bal Ram 
Published: November 2023

This paper analyzes English translations of Nepali short stories carried out by Nepali ESL/EFL student translators and examines the translators' manipulation of sentences across boundaries. The study adopted a product-oriented framework with a production task to elicit translation from 30 university translation students. The data were analyzed descriptively and discussed under three themes: sentence splitting, sentence joining and sentence-structure preserving. Findings show translators' tendency to preserve source-text sentence boundaries in target texts, with the minimum use of sentence-splitting and sentence-merging strategies to bring about shifts across sentence boundaries.

Published: November 2023

ABSTRAKDalam kasus tertentu terdapat terowongan percabangan tambang bawah tanah yang tidak teralirkan udara secara mekanis tetapi udara tetap mengalir secara alami teridentifikasi beraliran laminar. Studi ini memodelkan perpindahan momentum aliran laminar udara terowongan dengan dimensi rectangular atau Cartesian untuk memvisualisasikan profil distribusi kecepatan linier fluida dan profil tegangan geser fluida. Metode pemodelan menggunakan perhitungan analitik matematika dari persamaan gerak aliran fluida Newtonian untuk rejim laminar Navier-Stokes. Beberapa data yang dikumpulkan adalah dimensi terowongan, kecepatan linier udara, dan temperatur. Beberapa sifat fisik udara dikutip dari literatur. Hasil pengukuran kecepatan udara rata-rata diinputkan ke dalam model empiris untuk mendapatkan profil koordinat dua dimensi (x,z) untuk distribusi tegangan geser dan kecepatan udara yang mendekati keadaan sebenarnya untuk aliran laminar pada dimensi Cartesian. Hasil penelitian didapatkan pressure drop aliran sebesar 2,2 x 10-5 Pa, aliran mengandalkan perpindahan molekular bukan perpindahan secara konveksi paksa karena dilihat dari profil sebaran tegangan geser yang terlalu kecil dan laju alir sebesar 0,32 m3/s tidak memenuhi fungsi ventilasi tambang bawah. Kata kunci: perpindahan momentum; aliran laminar; fluida newtonian; ventilasi tambang. ABSTRACTIn certain case there is a mine tunnel branch that is not mechanically ventilated but air still flow naturally identified as laminar flow. This study modelled the momentum transport of the tunnel air laminar flow with rectangular or Cartesian dimensions to visualize the linear velocity distribution profile of the fluid and the fluid shear stress profile. The modelling method uses analytical mathematical calculations of the Newtonian fluid flow equations of motion for the laminar regime of Navier-Stokes. Some of the data collected are tunnel dimensions, air linear velocity, and temperature. Some physical properties of air are cited from literature. The results of the average air velocity measurement are input into the empirical model to obtain two-dimensional coordinate profiles (x,z) for the shear stress distribution and air velocity that are close to the actual situation for laminar flow in the Cartesian dimension. The results of the study obtained a pressure drop of the flow was 2,2 x 10-5 Pa, the flow using molecular transport instead of forced convection transport because seen from the shear stress distribution profile was too small and the flow rate was 0,32 m3/s did not fulfill the underground mine ventilation function.
