Published: June 2020

AbstarctPemphigus vulgaris is an autoimmune disease characterized by fluid-filled blisters over body and mucosal surfaces. Localized pemphigus is a rare presentation of the disease. There are few reports of localized pemphigus in literature presenting as esophageal involvement, recurrent paronychia, conjunctival mass, foot ulcers, discoloration of toes with hyperkeratotic skin lesions, verrucous lesions, and dyshidrosiform pemphigus vulgaris. We present a case of dyshidrosiform pemphigus involving a foot following trauma. Histopathology and direct immunofluorescence confirmed our diagnosis. In our patient, the disease started as localized dyshidrosiform pemphigus and later became generalized. This unusual presentation led to a delay in diagnosis and proper treatment in this patient. Physicians should be aware of such rare presentations to aid in the timely diagnosis and management of such patients.

Abstract
We study homotopes of alternative algebras over an algebraically closed field of characteristic different from

. We prove an analogue of Albert’s theorem on isotopes of associative algebras: in the class of finite-dimensional unital alternative algebras every isotopy is an isomorphism. We also prove that every

-homotope of a unital alternative algebra preserves the identities of the original algebra. We also obtain results on the structure of isotopes of various simple algebras, in particular, Cayley–Dixon algebras.

ABSTRACT

Flow regime is a key driver of invasive aquatic organisms, and the invasiveness of mangrove species may be simultaneously attributed to plant traits and flowing hydrological conditions at the estuary scale. We focused on hydrological and topographic conditions for a non-native mangrove species,
Sonneratia apetala
, in Zhangjiang Estuary of Fujian, China. A hydrological model and a micro-topographic model were used to predict its dispersal and early establishment, and field surveys and simulated experiments were integrated to estimate its future dispersal patterns. The mesohaline mudflat with a salinity of 8 ~ 10 PSU at the mangrove seaward edge was the most likely colonization area for
S. apetala
under current conditions. The south-western region of the estuary with native mangroves was the most likely area for its colonization according to the unstructured-grid finite-volume community ocean model (FVCOM) in September, when the largest tidal currents within a year and the maximum fruit maturity period occur. Approximately 42% of the mudflats throughout the whole estuary may be available for seedling establishment under the future sea-level rise RCP 4.5 scenarios compared with 44% for current establishment; however, the RCP 8.5 scenarios would significantly decrease seedling establishment by 2100 due to serious tidal inundation according to the micro-topographical model.

Abstract
A simple method was developed to prepare fluorescent nitrogen/boron-doped carbon dots (N,B-CDs) in the gram scale. The results showed that the CDs exhibited blue photoluminescence (PL) under 365 nm ultraviolet radiation and excitation-dependent emission. Heteroatoms entered the CDs to enhance the photochemical properties, and their positive properties can be attributed to the presence of guanidino group and functionalized with boronic acid for realizing their utilization in certain applications. These materials could be applied to monitor Fe3+ via static PL quenching, yielding a limit of detection (LOD) of 0.74 μM. Furthermore, the charged and boronic acid groups on the prepared N,B-CDs enabled their use as recognition elements to bind with the bacteria through electrostatic interaction and allowed covalent interactions to form the corresponding boronate ester with E. coli (E. coli) bacterial membrane. This method could satisfy a linear range of 102–107 with LOD of 165 cfu ml−1 for E. coli. This method was applied for the determination of E. coli in tap water and orange juice samples, and satisfactory results were obtained.

Published: June 2020

Abstract
Institut Teknologi Sepuluh Nopember (ITS) as one of the leading universities in Indonesia that is currently transforming into an internationally reputed research university, must have a plan for employee needs, in this case, lecturers who can meet the needs of the university in line with organizational change. Good Human Resource planning must be supported by complete data and information. One way to predict the needs of lecturers is to do time series modelling using data on the number of ITS lecturers in previous years. The time series modelling used is intervention modelling because the initial hypothesis of this study was the number of lecturers’ needs had a significant change when ITS changed to BLU and PTNBH. Based on the background description above, the purpose of this study is to obtain an appropriate time series intervention model to predict the number of ITS lecturers based on the model that has been produced. Based on the results of data analysis, the best intervention model is ARIMA ([4, 5], 1, 0). It means that the number of lecturers in the t-month is influenced by the number of lecturers in the 4th, 5th, 6th months ago, and the forecasting results show that the number of lecturers will decrease every month, so it is necessary to add the number of lecturers regularly every year.

Published: June 2020

Abstract
Mangrove is one of the most important ecosystems in Balikpapan, where the Proboscis monkeys-an endemic animal in Borneo-lives. The growth of their population is affected by the opening of pond land by human around the forest. In this research, the problem from the interaction among the growth rate of mangrove, monkey and the opened pond land is presented in a mathematics model in the form of prey-predator for those three variables. We give an attention to the model by introducing time delays for the growth rate of fish pond land. It shows that the linearized system performs a small perturbation and the value of critical delay of the characteristic equation will affects the stability of the equilibrium point and causes stability changes (Hopf bifurcation). In this work, we obtain the existence of a critical value of the time delay and the fulfillment of the transversal conditions.

Published: June 2020

Abstract
A new chaotic map is proposed from the composition of the improved logistic map and the MS map. The composition is done by mapping the MS map first, where the result is then mapped by the improved logistic map. The new map as the result of the composition is chaotic. This is shown by the Lyapunov Exponent analysis, bifurcation diagrams, and the NIST randomness test. The Lyapunov Exponent results with x0
= 0.1 are non-negative for r ∈ [1,4]. Its bifurcation diagrams with p ∈ (0,4) has a better density at r ∈ 2.5. The new chaotic function also passes 10 out of 16 NIST test, with initial value and parameter values x0
= 0.1, r = 2.5, and p = 2.5.

To confirm the analytical result, some numerical simulations are presented.
Inventory models for short life cycle clothing products use a logistic growth model
Authors: Lukitosari V , Subriadi A P 
Published: June 2020

Abstract
Clothes are products that follow short-life fashion and market demand. Products with a short lifetime occur due to technological developments and/or changes in market tastes. The clothing industry is one of the industries that has a short and obsolete sales period in stages. The excess number of products that accumulate in the warehouse due to obsolescence can cause the company to get a profit that is not optimal. One strategy to increase demand for the product is to apply discounts. There are two types of discounts used, namely a single discount and multiple discounts. The demand function of inventory model is considered analogous to the logistic growth model. The results show profit is maximized to get optimal order quantity and optimal discount price.

Published: June 2020

Abstract
We have built an electronic instrument of water pump control system for rice field irrigation. This instrument is developed from our previous prototype with some additional features. This instrument is equipped with the keypad, GSM modem, water flow sensor, and relay as the input sources. An Arduino Mega 2560 is used as the main controller of the system. The working time of the water pump can be set using the keypad or short message service, which is received by GSM modem in the instrument. If there is no water flowing through the water pump as detected by the water flow sensor, the instrument will automatically shut down the water pump, and send the notification message to the user’s handphone. When the abnormal condition is detected on the water pump, the relay will disconnect the electricity to avoid the severe damage of the water pump. This instrument has been installed and used by the farmer in Desa Ngunut, Babadan District, Ponorogo Regency, with support from DRPM Kemenristekdikti through Program Kemitraan Masyarakat.

Published: June 2020

Abstract
The province of Bangka Belitung in Indonesia has a potential of ocean fishery production of about 1, 200, 000 tons per year. On the other side, there is another oppurtunity for the government to take advantage of the mainland usage for ocean fishery. Vannamei shrimp is one of the fishery product that can be farmed on mainland. Nowadays there are numbers of Vannamei shrimp’s company in Bangka Belitung. Feeding process of Vannamei shrimp is one problem in this business. The food residual can cause about 60% of organic waste. To anticipate this problem, an automatic feeder has been developed, even though they are not optimized yet. The propose of this study was to design a new method of automatic feeder which can spread the pellets from 0 to required distance in meters and of a food transporter that can flow pellets properly. The machine has been designed to be operated using android-based system. This brings the ease of use to control and monitor the feeding process. The result shows that the automatic feeder can achieve 15 meter in maximum distance of food throwing. Spreading the food can be from 0 up to 15 meter based on the speed controlling of throwing (0 to 700 rpm). The auto-feeder can also be monitored using android system such as the volume of the food, and on/off the system manually.
Plasma intensification in 2 MHz RF glow discharge in carbon film plasma sputtering deposition by means of a hollow cathode

Published: June 2020

Abstract
A hollow cathode has been one of the methods to intensify the plasma in the etching or ashing process. This work examined a number of technologies in the intensification of a 2 MHz RF glow discharge plasma to deposit carbon film by means of the hollow cathode. Three types of the cathode configurations, which were cylindrical, rectangular and a cylindrical-rectangular combination, were tested to get an optimum condition for the carbon deposition. Both carbon target and substrate were fixed inside the hollow cathode. The plasma was characterized by means of optical emission spectroscopy (OES) at the range of 200 nm – 1000 nm. The results showed that the combination where the rectangular hollow was placed inside the cylindrical one, produced the most intense glow. Ion density and electron temperature in the plasma were determined by a calculation based on the atomic data related to the specific electronic transitions of the ions. The density of ions was very high in the centre area of the rectangular hollow producing complex reactions. On the other hand, the high density of the ions decreases the electron temperature. The energy of the ions was difficult to be predicted since the spectrum showed the existence of a large number of ion states. Observations on the resulted deposit on the surface of quartz substrate suggest that the intensification needs to be further investigated related to the effectiveness of sputtering and deposition process.
