Authors: Qirom Muhamad Syahidul , Dahlan Jarnawi Afgani , Turmudi Turmudi 
Published: August 2023

Some research about identifying the differences between male and female students’ written communication skills has been done before. However, the previous research only focused on qualitative studies. Therefore, there is still a lack of empirical proof of the result. This study aims to test whether a significant difference exists between male and female students' written mathematical communication skills and identify their performance difficulties. The subjects were 14 male and 14 female students at the junior high school. The instrument was a test of mathematical communication skills on quadrilateral topics. The research method used was a mixed method with a sequential explanatory design. The data were analyzed using Mann-Whitney U to measure the difference between male and female students’ written mathematical communication skills, and document analysis was conducted to analyze their difficulties in performing written mathematical communication. The results showed that even though there is no significant difference between written mathematical communication skills between male and female students, there is a significant difference when viewed from each indicator. In addition, the difficulties experienced by male and female students are difficulties expressing mathematical ideas using mathematical symbols, using facts and concepts to solve problems, and operating algebraic forms.

Abstract
The test procedures for determining Young’s modulus in concrete are complicated and time-consuming. Therefore, attempts to search for alternative methods of its determination are not surprising. The relationship between the value of compressive strength and Young’s modulus in concrete is known. However, the strength of this relationship in fibre-reinforced concrete has not been exactly described. The article attempts to investigate the strength of the correlation between Young’s modulus and the compressive strength of fibre-reinforced concrete. The influence of the amount of fibres on this relationship was also checked. Two types of specimen were used for the tests. The specimens differed in the content of steel fibres, 0.25% and 0.50%, respectively. In order to determine the correlation relationship, the method of linear regression and the coefficient of linear correlation were used. The use of the determination coefficient allowed us to examine the degree of explanation of one variable by another.

Abstract
This paper presents a novel method for measuring the data for evaporation estimation as the key ingredient for the final decision of the reclamation form in the area of the Most Basin. The area has been intensively mined for many decades, resulting in significant landscape devastation, loss of natural habitats, and negative environmental impact. Currently, it is assumed that by 2050, three large-scale reclamation projects will be implemented in the area and it is necessary to decide which form of reclamation to choose. Whether to build lakes according to the currently valid rehabilitation and reclamation plan or to leave the area of the quarries in succession with the support of spontaneous inflow of water up to a naturally sustainable water level. Whether the first or second option is approved, or a combination of both, the prediction of evaporation from the free water surface will always be of great importance. To deal with this goal, the available meteorological data must be combined with a suitable calculation method. In our work, we suggest utilizing a measuring network of meteorological devices that describe the character of the weather in a given area of interest in a long-term time series. Together with the state-of-the-art calibration of models for calculating evaporation, the measurement network helps to provide more accurate evaporation data for a given area. Based on the analysis of research results, it will be possible to choose a specific right decision and thus contribute to the long-term sustainability of these reclamations.
An Acute Anterior Reinfarction Complicating with Transient Symptomatic Total Atrioventricular Block
Authors: Hendiperdana Mochamad Rizky 
Published: August 2023

Abstract
Background
Acute stent thrombosis is a frequent cause of myocardial infarct (MI) after stent placement. Total atrioventricular (AV) block is frequently become the conductive disturbance complication of acute reinfarct. Inferior MI has Low long-term mortality and greater reversibility than anterior MI which has higher in-hospital and long-term mortality.

Case Illustration
44 years man, came to emergency department Cardiovascular Centre Harapan Kita with altered mental status since 12 hours ago. PPCI stenting at proximal LAD of his acute anterior MI 2 days ago. Patient had acute stent thrombosis then underwent urgent PCI at referring hospital. Patient present with blood pressure 57/30, heart rate 20 -30 with TAVB rhythm. Laboratory showed increased serum lactate level 5.2. Patient was diagnosed with Total AV block caused by MI. Patient was planned for emergency temporary pacemaker (TPM) implantation. After 24 hours close monitoring, the patient intrinsic rhythm resolved with spontaneous recovery. Patient was hemodynamically stable until discharge.

Discussion
Stent thrombosis of proximal stent of LAD will cause TAVB because of the source of the distal portion of the AV node is originating from septal branch of LAD. It is caused by extensive necrosis with higher in-hospital and long-term mortality, often culminated in permanent pacemaker. However, spontaneous recovery of TAVB into sinus rhythm take place. This could be caused by transient reversible ischemia of infra nodal region of AV node which supplied by septal perforator branch

Conclusion
This case reporting a complete atrioventricular block during the course of acute anterior reinfarct and had spontaneous resolution of the AV block. Mechanisms of spontaneous resolution of complete AV block in the setting of acute MI is associated transient ischemia after occlusion of proximal LAD.

Does Chronic Inflammation Play a Role in Rheumatic Mitral Valve Restenosis after Percutaneous Transvenous Mitral Commissurotomy?
Authors: Soesanto Amiliana M 
Published: August 2023

ABSTRACT
Background: Mitral valve restenosis is defined as decreased mitral valve area (MVA) <1.5 cm2 or decreased MVA >50% after PTMC. It is time-dependent and associated with major adverse cardiovascular events (MACE), such as congestive heart failure, cardiac death, mitral valve replacement, and redo PTMC. The mechanism is not yet known; however, chronic inflammation may have a role. Objective: To know the association between chronic inflammation and mitral valve restenosis after PTMC. Methods: A total of 40 patients with mitral valve stenosis who underwent successful PTMC were matched and classified into restenosis/case group (n=20) and no restenosis/control group (n=20). Secondary data was taken from electronic medical records such as patient characteristics (gender, age & 2nd prophylaxis), echocardiography data before PTMC (Wilkins’ score and MVA before PTMC), and echocardiography data after PTMC (MVA after PTMC). Follow-up echocardiography examination (follow-up MVA) and laboratory assessment of chronic inflammation marker (IL-6) were done on all patients. Statistical analyses were done to look for an association between the level of chronic inflammation marker & other independent variables with mitral valve restenosis. Results: Median IL-6 concentration was 2.39 (0.03 – 11.4) pg/mL. There was no statistically significant difference in IL-6 levels between both groups (p-value >0.05). MVA decrement was 0.13 (0 – 0.62) cm2/year with rate of MVA decrement ≥0.155 cm2/year was predictor of mitral valve restenosis (p-value <0.001, OR = 46.72, 95% CI 6.69 – 326.19). Conclusion: Chronic inflammation assessed by IL-6 was not associated with mitral valve restenosis.

Published: August 2023

The development of science-based technologies of cultivation makes it possible to reveal the productive potential of new varieties of perennial grasses. In 2021-2022 in the conditions of the Penza region, there were studied the seeding rates and methods of sowing of a new variety of awnless brome Udalets when cultivated for seed. According to the hydrothermalcoefficient, the growing season of 2021 was characterized as dry (HTC = 0.8), 2022 – as normal in terms of moisture supply (HTC = 1.0). The best indicators of the development of brome plants (mass of plants and roots) by the end of the first year of life were obtained using a wide-row sowing method with row spacing of 30 cm at a seeding rate of 5.0 million viable seeds per 1 ha. In terms of the yield of green mass and the collection of dry matter from 1 m2 in the first year of life, the wide-row sowing method with a row spacing of 30 cm had an advantage. During the year of awnless brome grass use the best indicators of seed yield were obtained by wide-row sowing method with row spacing of 30 cm at a seeding rate of 5.0 million viable seeds per 1 ha. At the same time, the number of productive stems was 106 pcs/m2, the length of the inflorescence was 19.0 cm, the number of spikelets in the inflorescence was 182 pcs., the weight of seeds from a productive shoot was 0.78 g, the weight of 1000 seeds was 4.26 g, which was 8.2; 8.0; 11.0; 13.0; 0.9 %, respectively, higher than the control variant with a row sowing method with row spacing of 15 cm at a seeding rate of 6.0 million viable seeds per 1 ha. The highest seed yield of awnless brome in the first year of use was formed with a wide-row sowing method with row spacing of 30 cm at a seeding rate of 5.0 million viable seeds per 1 ha (824 kg/ha), the increase over the control was 146 kg/ha, or 21.5 %. By a row method of sowing with row spacing of 15 cm, a high yield was obtained in the control variant (6 million viable seeds/ha) – 678 kg/ha. With a seeding rate of 5.0 million germinating seeds per 1 ha, the seed yield decreased by 7.6 %.
Strengths and Limitations of The Indonesian Constitutional Court’s “6 Basic Principles” in Resolving Water Conflicts
Authors: AlAfghani Mohamad Mova 
Published: August 2023

Many parts of Indonesia are already experiencing water stress and the condition is expected to become worse by 2045, when, according to the World Bank, 67% of Indonesia’s GDP will be produced in areas with high water stress. Conflict over water resources has been reported between water users and uses, such as between agriculture and drinking water, between agricultureand fisheries, and between farmers and industries. In 2015, responding to the petition to curtail private sector control over water resources, the Constitutional Court invalidated Water Law 7/2004 and introduced the 6 basic principles, that have been used as normative guidance for implementing the regulation on water resources and for resolving future water conflicts. However, the principles are ambiguous in many ways. This paper will critically examine the principles and then outline the difficulties in its implementation. The methodology employed is normative-analytical; incorporating analytical frameworks from water law and governance into constitutional adjudication. First the paper clarifies some conceptual frameworks related to water conflict and how the principles have been interpreted by regulators. The paper then explains the general categories of water conflict and where those principles would, or would not, fit. The paper then continues with a critique of the principles, in terms of their (i) unclearscope, (ii) conflation between users and uses, (iii) neglect of footprint and (iv) the implications for water reallocation. This paper finds that one of the strengths of the principles is that they provides a basic normative guidance for solving conflict in water allocation, the protection of human rights and the environment. However, these benefits come with some limitations: neglect of efficiency over perceived equity and potential restriction of reallocation of water among different users. The principles are also difficult to implement where there is conflict over water quality or spatial development. As such, the paper recommends that the Constitutional Courts revise and expand the principles in future cases using teleological approach and that in terms of implementation, the 6 basic principles should also be interpreted teleologically.

Samenverbreitung der Weisstanne im Berner Allmiwald
Authors: Wattenwyl Kim Fabian von , Kupferschmid Andrea Doris , Thormann Jean-Jacques 
Published: August 2023

Abstract
Samenangebot und -verbreitung beeinflussen die natürliche Verjüngung einer Baumart massgeblich. Um abzuschätzen, ob eine Baumart einen Standort neu besiedeln kann, sind Kenntnisse über die Verbreitungsdistanzen der Baumsamen eine wichtige Grundlage. In der Schweiz könnten Weisstannen mit der Klimaerwärmung z.B. zunehmend in die subalpine Höhenstufe vordringen. Im hochmontanen Gebiet der Underen Dorfflüe des Allmiwaldes oberhalb von Saanen (BE) wurden die Positionen von potenziellen Samenbäumen der Weisstanne erfasst und die nächsten zwei Tännchen mit 0–130 cm Baumhöhe in 54 systematisch angelegten Probeflächen aufgenommen. Anhand der kleinsten Distanz zwischen Samenbaum und Verjüngung wurde die minimale Verbreitungsdistanz der Tanne bestimmt. Zudem wurden Daten zur Lichtverfügbarkeit, Wildverbiss und Kleinstandort (Kleintopografie, Bodenvegetation und Humusform) je Probefläche erhoben. Die errechneten Verbreitungsdistanzen lagen zwischen 3.0 und 97.9 m, bei einem Median von 30.2 m. Mit zunehmender Distanz zu potenziellen Samenbäumen der Weisstanne nahmen die Verjüngungsdichten signifikant ab. Von den weiteren Einflussfaktoren hatte nur das direkte Licht einen signifikant positiven Effekt auf die Verjüngungsdichte. Der Anteil verbissener Tannen &gt;10 cm lag bei sehr hohen 82%. Auch wenn Weisstannensamen in der Lage sind, grössere Distanzen zu überwinden (maximale Distanz ca. 190 m), können hohe Samendichten besonders innerhalb einer Baumlänge erwartet werden. Letztlich bestimmt also der gewünschte Mischungsanteil an der Verjüngung die erforderliche Samenbaumdichte der Tanne. Die Präsenz von Weisstannensamenbäumen alleine ist aber kein Garant für Tannenverjüngung; die Lichtverhältnisse und der Verbiss durch Wildtiere spielen ebenfalls eine wichtige Rolle in der Etablierung von Tannenverjüngung.
