Published: August 2024

Rumah kos merupakan penyedia jasa tempat tinggal sementara yang dibayar dalam kurun waktu tertentu. Biasanya pemilik rumah kos akan membebankan penggunaan listrik dan air kepada penghuni kamar kos. Untuk penggunaan listrik dapat diisi ulang dengan token. Namun, berbeda dengan penggunaan air bersih, pemilik kos hanya menyediakan beberapa toren dan dialirkan ke kamar-kamar kos tanpa tahu volume dan biaya per kamar kos, sedangkan kebutuhan air bersih berbeda tiap individu. Maka pada penelitian ini, dirancang sebuah perangkat yang dapat memonitoring volume dan biaya pengunaan air bersih secara real time. Terdapat 2 buah mikrokontroler NodeMCU ESP8266 yang terhubung ke internet dan dan sensor water flow. Sistem kerja alat terbagi menjadi dua bagian yaitu transmitter dan receiver. NodeMCU pertama sebagai receiver dan NodeMCU kedua sebagai transmitter. Pada bagian transmitter, sensor water flow akan mendeteksi adanya aliran air, kemudian informasi akan diproses dan akan dikirimkan receiver. Bagian receiver akan menerima informasi dan akan menampilkan data pada LCD dan aplikasi Blynk. Setelah dilakukan pengujian, diperoleh bahwa perangkat dapat berfungsi sesuai rancangan dengan rata-rata akurasi pembacaan sensor sebesar 94.25%.

Abstrak. Penelitian ini bertujuan untuk menghasilkan rekomendasi strategi penjualan bundling yang efektif untuk Cafe SZ Point, sebuah UKM yang berlokasi di Jalan Sambikerep No.25, Sambikerep, Kec. Sambikerep, Surabaya, Jawa Timur. Cafe SZ Point baru memulai usahanya pada 11 Maret 2023. Sebelumnya, kafe ini pernah melakukan promosi bundling yang kurang efektif sehingga mengakibatkan kerugian dan penurunan pendapatan. Hal ini terjadi karena kafe tersebut belum memaksimalkan penggunaan data penjualan dari lunapos untuk mengidentifikasi tren konsumen, pola pembelian, dan preferensi pelanggan. Tanpa pemanfaatan data penjualan yang optimal, strategi pemasaran yang tepat sasaran sulit dirancang.Penelitian ini menggunakan algoritma Frequent Pattern Growth (FP-Growth) melalui pendekatan metode CRISP-DM (Cross-Industry Standard Process for Data Mining) untuk menganalisis data transaksi dari Cafe SZ Point dan menemukan pola pembelian pelanggan yang sering muncul. Hasil analisis menunjukkan dapat diterapkan untuk menentukan pola pembelian menu dengan membentuk aturan asosiasi yang dapat digunakan untuk strategi penjualan. Rekomendasi strategi bundling yang dihasilkan dari penelitian ini diharapkan dapat membantu Cafe SZ Point dalam meningkatkan performa penjualannya. Abstract. This research aims to produce recommendations for an effective bundling sales strategy for Cafe SZ Point, an SME located on Jalan Sambikerep No.25, Sambikerep, Kec. Sambikerep, Surabaya, East Java. Cafe SZ Point just started its business on March 11 2023. Previously, this cafe had carried out bundling promotions that were less effective, resulting in losses and a decrease in income. This happens because the cafe has not maximized the use of sales data from LUNAPOS to identify consumer trends, purchasing patterns and customer preferences. Without optimal use of sales data, targeted marketing strategies are difficult to design.dThis research uses the Frequent Pattern Growth (FP-Growth) algorithm using the CRISP-DM (Cross-Industry Standard Process for Data Mining) method approach to analyze transaction data from Cafe SZ Point and find customer purchasing patterns that frequently appear. The analysis results show that it can be applied to determine menu purchasing patterns by forming association rules that can be used for sales strategies. It is hoped that the bundling strategy recommendations resulting from this research will help Cafe SZ Point improve its sales performance..

Optimization of bantuan pangan non tunai (BPNT) distribution using bilevel linear programming in siantar martoba subdistrict pematang siantar
Authors: Panggabean Rijen Riston , Sinaga Lasker Pangarapan 
Published: August 2024

Bantuan Pangan Non Tunai (BPNT) is assistance that is in the second decile; in other words, KPMs who are in the first decile will also get assistance. A limited quota of BPNT recipients will result in people in categories such as the elderly group not getting this assistance. This problem arises because there is a significant increase in the population of the elderly group every year. The research method uses secondary data from data sources, namely the social service office, to develop a bilevel model for the problem of distributing food aid on cash by regularizing the bilevel model so that a linear programming model with a single objective function is obtained. In the regularization stage, the gradient descent method is used to find the optimal value of the penalty parameter. From the calculation results of the regularized model, it is found that the values of the variables x_1= 2956, x_2= 583, and x_3 = 250 have a value of Z = 3804. This bilevel linear programming model approach provides a strong basis for planning and decision-making related to the distribution of Non-Cash Food Assistance (BPNT) in Siantar Martoba Subdistrict. Therefore, it can be assumed that this bilevel linear programming approach can be used as a guideline for related agencies in allocating resources efficiently.
Prototyping Self-Sustaining Power Machines with Cascaded Power Units Composed by Pulse Gas Turbines
Authors: Ferreiro Garcia Ramon 
Published: August 2024

This research work aims at designing a prototype of a disruptive Self-Sustaining Power Machine (SSPM) composed of cascaded power units (PUs). Each PU consists of a Pulse Gas Turbine (PGT). The prototyping design task involves a singular thermal cycle (sVsVs) associated to each PU, characterized by doing work by: of a Thermal Working Fluid (TWF) due to previous heat addition, contraction of a TWF previously cooled by heat extraction and, upgrading recovered heat by increasing thermal potential by heat superposition techniques, and efficiexpansion ent use of the heat recovered from each upstream PU to feed the first PU downstream.
The fact of achieving useful mechanical work with the above-mentioned procedures by adding only heat to produce expansion work, undergoes an excess of useful mechanical work greater than the amount of added heat, which gives rise to a SSPM enabled to defy Perpetual Motion Machines (PMM) of second kind.
In the proposed configuration, the heat released from each PU due to the cooling of the TWF is efficiently recovered and reused in the first PU in the cascade. Results have been verified through two case studies carried out on a SSPM simulated prototype, being conducted using air and helium as real gases.
According to the results, the SSPM composed by a group of cascaded PUs, each exhibiting an average efficiency of less than 35% with air as TWF, can approach a SSI of 22% while the SSPM composed by a group of cascaded PUs, each exhibiting an average efficiency of less than 57% with helium as TWF, can approach a SSI of 84 %. Consequently, the results achieved from the case studies of the SSPM indicate that it is possible to overcome second kind PMMs.

Published: August 2024

Objectives:
The objective of this study was the assessment of the ameliorative roles of alpha-tocopherol and quercetin on the toxic mechanisms associated with ethanol (EtoH) exposure in the cardiac and renal systems of rats.

Material and Methods:
Forty male rats were randomly selected and divided into five groups as follows: 0.2 mL distilled water; EtoH 40% v/v; EtoH + 2.5 mg/kg alpha-tocopherol; EtoH + 50 mg/kg quercetin; and EtoH + a cocktail of alpha-tocopherol and quercetin.

Results:
Treatment with alpha-tocopherol and quercetin significantly (P < 0.05) ameliorated EtoH-induced alterations in hemodynamic and electrocardiographic parameters, kidney function markers, and antioxidant defense status of rats with significantly elevated levels of glutathione, glutathione peroxidase, superoxide dismutase, and glutathione-S-transferase observed in antioxidant-treated rats. Histopathologic lesions induced by EtoH including focal loss of myofiber striation, degeneration, and infiltration of inflammatory cells in the cardiac tissues, as well as patchy tubular necrosis, congestion, and ectasia in renal tissues were absent in the antioxidant treated rats. Heightened immunohistochemical expressions of cardiac-specific troponin and angiotensin converting enzymes induced by EtoH were abated by alpha-tocopherol and quercetin treatment.

Conclusion:
Alpha-tocopherol and quercetin mitigated oxidative stress-mediated ethanol-induced derangements of the cardiovascular and renal systems in rats.
Clinical implications of activation of the LIMD1-VHL-HIF1α pathway during head-&-neck squamous cell carcinoma development
Authors: Mukhopadhyay Debalina , Chakraborty Balarko , Sarkar Shreya , Alam Neyaz , Panda Chinmay Kumar 
Published: August 2024

Background & objectives
Given the importance of the role of hypoxia induced pathway in different cancers including head-and-neck squamous cell carcinoma (HNSCC), this study delved into elucidating the molecular mechanism of hypoxia-inducible factor-1α (HIF1α) activation in HNSCC. Additionally, it analyzes the alterations of its regulatory genes [von Hippel–Lindau (VHL) and LIM domain containing 1 (LIMD1)] and target gene vascular endothelial growth factor (VEGF) in head-and-neck lesions at different clinical stages in relation with human papillomavirus (HPV) infection.

Methods
Global mRNA expression profiles of HIF1α, VHL, LIMD1 and VEGF were evaluated from public datasets of HNSCC, followed by validation of their expression (mRNA/protein) in an independent set of HPV+ve/–ve HNSCC samples of different clinical stages.

Results
A diverse expression pattern of the HIF1α pathway genes was observed, irrespective of HPV infection, in the datasets. In validation in an independent set of HNSCC samples, high mRNA expressions of HIF1α/VEGF were observed particularly in HPV positive samples. However, VHL/LIMD1 mRNA expression was low in tumours regardless of HPV infection status. In immunohistochemical analysis, high/medium (H/M) expression of HIF1α/VEGF was observed in basal/parabasal layers of normal epithelium, with significantly higher expression in tumours, especially in HPV-positive samples. Conversely, high cytoplasmic VHL expression in these layers gradually decreased with the progression of HNSCC, regardless of HPV infection. A similar trend was noted in LIMD1 expression (nuclear/cytoplasmic) during the disease development. The methylation pattern of VHL and LIMD1 promoters in the basal/parabasal layers of normal epithelium correlated with their expression, exhibiting a gradual increase with the progression of HNSCC. The H/M expression of HIF1α/VEGF proteins and reduced VHL expression was associated with poor clinical outcomes.

Interpretation & conclusions
The results of this study showed differential regulation of the LIMD1-VHL-HIF1α pathway in HPV positive and negative HNSCC samples, illustrating the molecular distinctiveness of these two groups.

Most of the Long-Term Solar Radiation Forcing on the Climate Is Due to the Strong Feedback Mechanisms
Authors: Abdussamatov Habibullo I. 
Published: August 2024

The main interactions of the Total Solar Irradiance (TSI) variations with the climatic system are considered. This research introduced new physically based indexes for 11-year cycles: the integral relative energetic power of the cycles solar activity (SA) and TSI, as well as the cycle-weighted mean value both of the TSI and sunspot number. The observed cycle-average TSI value in cycles XXII–XXIV has decreased by more than 0.5 W/m2, indicating its quasi-bicentennial decline. The onset of the Maunder-type Grand minimum phase of the SA and TSI of the quasi-bicentennial cycle (BCC) is expected in the 27th or 28th 11-year cycle in 2042 or 2053. The Earth's thermal inertia will cause a temperature reduction of around 0.25 K due to the deficit in TSI during the declining phase of the bicentennial cycle due to its negative impact on Earth's energy imbalance. As a result, the Bond's albedo will increase, and the abundance of atmospheric water vapor and carbon dioxide will decrease as a response to a direct solar forcing. BCC feedback mechanisms will also continue operating during both its minimum and maximum phases. The feedback mechanisms will continue further in short periods (about 30 years) at the beginning of BCC's growth and decline phases. These long-term self-reinforcing feedback effects will act as a response to the TSI, forcing in such a way as to trigger a strong amplification of the initial direct input to the corresponding temperature changes. They will lead to a significant increasing cooling in 2070 or 2080. Variations of the galactic cosmic rays and cloud cover practically do not affect the climate. The quasi-bicentennial cyclicity of the TSI also provides simultaneous climate variations on all Solar system planets.
