Published: June 2023

Youtube adalah sosial media yang banyak digunakan orang untuk share video yang berisi bermacam jenis content. Pemakai tidak terdaftar bisa melihat video, sementara pemakai terdaftar bisa mengupload video serta memberi komentar dengan jumlah tidak terbatas. Biasanya beberapa video di YouTube yaitu clip musik (video klip), trailer film, video edukasi, video ulasan, dan video diskusi, debat atau dialog. Komentar dan opini pengguna di Youtube dapat dipakai sebagai indikator untuk melihat kecondongan pemakai pada pasangan calon kepala daerah yang berkaitan, hingga data komentar tersebut bisa menjadi sumber data opini dan sentimen masyarakat pada satu studi sosial.

Pada suatu timses pasangan calon Pemilihan kepala daerah, sentiment analysis dipakai sebagai alasan penetapan kebijakan serta taktik kampanye untuk menaikkan kepopuleran jago mereka serta untuk testing calon mereka di mata masyarakat apa bisa terima secara baik atau belum.

Support Vector Machine (SVM) merupakah salah satu model sentiment analysis. SVM tergolong dalam kelompok algoritme dengan tehnik supervised (diawasi). Dalam tiga kelompok kategorisasi yang dipakai dalam SVM akan mencari nilai maksimal hyperplane yang membagi ruangan pengetesan menjadi kelas-kelas yang terpisah satu yang lain. SVM termasuk algoritme komputasional yang memerlukan operasi yang besar lantaran menyertakan diskretisasi, normalisasi serta operasi titik produk yang berulangulang.

Diharapkan dengan Support Vector Machine (SVM) ini bisa mengolah data komentar pada video debat calon pimpinan daerah yang berada di Youtube secara automatis serta seterusnya bisa mengklasifikasi sentimen analisis komentar masyarakat terhadapcalon kepala daerah yang akan dilaksanakan, hingga menjadi referensi untuk lebih lanjut buat yang berminat untuk mengembangkannya.

Published: June 2023

Penampilan memakai masker bagi sebagian orang penting untuk menunjang penampilan dan mengutamakan faktor kenyamanan. Saat mencoba masker, calon pembeli sebaiknya datang langsung ke apotek atau toko. Sehingga waktu yang dimiliki calon pembeli maupun penjual menjadi tidak efisien. Karena seringna berganti-ganti jenis masker yang akan digunakan untuk dibeli, hal tersebut mendapatkan risiko yang dapat merusak masker dengan mencoba masker asli dan risiko harus membelinya pula. Oleh karena itu, dibutuhkan sebuah media bantu dalam bentuk aplikasi dengan fitur Augmented Reality yang berguna dalam melihat tampilan masker pada kontur wajah melalui smartphone tanpa harus mencoba masker aslinya satu per satu. Aplikasi ini dapat berjalan dengan proses menggabungkan model masker di dunia maya dengan wajah pengguna di dunia nyata yang ditangkap oleh kamera smartphone pengguna. Metode penelitian dalam proses pengembangan aplikasi ini berupa studi pustaka, analisis kebutuhan, perancangan aplikasi, pengembangan aplikasi, dan pengujian aplikasi. Pengembangan aplikasi dilakukan dengan menggunakan metode pelacakan wajah dalam teknologi Augmented Reality. Dengan adanya aplikasi ini, model masker 3 dimensi dapat ditampilkan langsung pada wajah pengguna pada platform Android. Untuk mendapatkan hasil terbaik, uji aplikasi dengan menguji kompatibilitas aplikasi saat digunakan pada perangkat yang berbeda dan melakukan pengujian UAT (User Acceptance Testing) untuk mengetahui penilaian mengenai aplikasi dari pengguna dan didapatkan hasil UAT yang tergolong baik berdasarkan pada hasil uji coba beserta kuesioner yang memperoleh nilai sebesar 83.25%.

Published: June 2023

Greenhouse merupakan sebuah bangunan kontruksi yang berfungsi untuk memanipulasi kondisi lingkungan agar tercipta kondisi lingkungan yang dikehendaki. Hal ini berguna untuk mengoptimalkan pemeliharaan tanaman, pengkondisian lingkungan yang dilakukan pada greenhouse meliputi pengaturan suhu dan kelembaban udara, pengaturan suhu dan kelembaban tanah serta penyiraman yang baik. Permasalahan yang terjadi adalah kurang meratanya sebaran suhu dan kelembaban udara serta tanah di semua area greenhouse yang pada akhirnya akan mempengaruhi pertumbuhan tanaman di area tersebut. Hal ini dapat diatasi dengan penambahan perangkat pintar pada greenhouse untuk menganalisis suhu dan kelembaban di dalam greenhouse. Analisis suhu dan kelembaban di dalam greenhouse bertujuan untuk memaksimalkan iklim mikro untuk pertumbuhan tanaman dengan cara mengukur kondisi suhu, kelembaban udara dan kelembaban tanah tanpa memanfaatkan alat otomatis pengatur suhu dan kelembaban lingkungan. Kemudian dilakukan analisis kondisi lingkungan dengan penambahan perangkat sensor dan menambahkan sprayer dan fan yang terhubung ke sensor pengukur suhu dan kelembaban tanah serta udara. Pada penelitian ini digunakan sensor suhu dan kelembaban udara DHT11, sensor kelembaban tanah YL 69. Sensor dihubungkan ke mikrokontroler Arduino UNO untuk melakukan perintah ke sprayer dan fan. Sebelum merancang sistem otomasi, dilakukan analisis terhadap jangkauan fan dan sprayer yang digunakan. Dari analisis yang dilakukan kemudian area greenhouse dibagi menjadi 8 lines pengukuran. Berdasarkan penelitian yang telah dilakukan diperoleh kesimpulan bahwa dengan penggunaan alat otomatis pengatur suhu dan kelembaban udara dan tanah, maka sebaran suhu dan kelembaban menjadi lebih merasa, iklim mikro yang dihasilkan dapat mendukung pertumbuhan tanaman. Sebelum otomasi persebaran iklim mikro greenhouse tidak merata pada setiap titik dan setiap waktu, sedangkan setelah otomasi persebaran menjadi rata. Optimasi dapat dilakukan lebih baik lagi apabila memperhatikan kebutuhan tanaman berdasarkan jenis tanaman yang dibudidayakan.

One-fourth of Indonesia's Gross Domestic Product or GDP is from the manufacturing industry sector. Indonesia's government has proactively encouraged companies to increase their production capacity to meet the global demands, leading to strong demand for employees to work harder, affecting the workers' health. Overwork is often associated with fatigue, stress, and various health problems. Moreover, stress due to excessive work is a general problem many industries face and frequently influences workers' performance.  Therefore, this research intends to examine the relationship between work stress and workers' performance, particularly in the manufacturing industry in Indonesia. The sample data are collected from ninety-three workers at the staff level across various companies in the manufacturing sector. The relationships between the determining factors and the Employee Productivity are evaluated by using the multivariate regression analysis. At the correlation coefficient of 0.972, we found a statistically strong relationship between the work environment and Stress to the workers' performance. The condition of low performance is attributed to the non-standard working hours and low quality of the relationship between colleagues and their superiors. Finally, the research recommends improved management of workers' stress by companies involving the adoption of flexible working hours and better communication between parties via discussion forums and meetings. Therefore, employees will be more motivated to improve work productivity.

Authors: Margaret Fredlina , Ali Fakhrudin Sofwan , Dithya Pratiwi Ariska , Gunawan Fergyanto E.
Published: June 2023

Queues are often found in everyday life, such as waiting for cinema counters, check-in queues at airports and self-service cashier queues. Service facilities for a long time cause queues because they cannot meet the needs or capacity, so facility users have to wait. As in the example of the case of Cinema Z in Solo City has a maximum queue time of 13.6 minutes with a maximum number of queues of 11 people until served.  This can cause customers to wait long enough to get movie tickets. This problem can be overcome by the need to manage the counter operator so that it can regulate when to open a new counter so that there is no queue. This research discusses the problem of queuing models at Cinema Z in Solo, Central Java Province. From the results of the analysis that can be known the performance values of the queuing system such as waiting time, number in, number out, dan number waiting.

MÁS ALLÁ DEL FORMALISMO: el compromiso social de Giancarlo De Carlo
Authors: Romano Antonella
Published: June 2023

Giancarlo De Carlo, arquitecto, urbanista y ensayista, fue uno de los protagonistas más complejos y comprometidos de la cultura arquitectónica italiana e internacional de la segunda mitad del siglo XX.  El interés por su figura se expresa en las numerosas iniciativas, exposiciones y publicaciones en torno al centenario de su nacimiento. En todas ellas, está el corazón del pensamiento y de la obra de De Carlo; la valiosa relación entre ser humano, medio ambiente y la comunidad. En este escrito, proponemos una revisión crítica de su obra que vaya más allá de la así la “arquitectura de la participación”, ya que puede abrir caminos de investigación sobre temas de actualidad: el vínculo inseparable entre arquitectura y urbanismo; la relación entre experiencia existencial y espacio construido en el diseño del paisaje, la ciudad, los centros históricos; el proyecto de reutilización de obras existentes; la construcción continua de una visión de la arquitectura para “diseñar pensando en el futuro” y “abrir procesos en lugar de cerrar soluciones”.
Synchronous implementation of simultaneous multiple captures of evaders
Authors: Blagodatskikh A.I.
Published: June 2023

The problem of pursuit of a group of $m$ evaders $(m\geqslant 1)$ in conflict-controlled processes with equal opportunities is considered. It is said that in the problem of chasing one evader $(m = 1)$, multiple capture occurs if a given number of pursuers catch him, and the moments of capture may not coincide. In the problem of simultaneous multiple capture of one evader, it is required that the moments of capture coincide. Simultaneous multiple capture of the whole group of evaders $(m \geqslant 2)$ occurs if, as a result of pursuit, each evader is repeatedly caught simultaneously, and at the same time. In terms of the initial positions of the participants, necessary and sufficient conditions for the simultaneous multiple capture of the whole group of evaders are obtained.
Designing asymptotic observers for linear completely regular differential algebraic systems with delay
Authors: Khartovskii V.E.
Published: June 2023

We study the problem of generating a solution estimate based on the observed output signal data for linear autonomous completely regular differential algebraic systems with commensurate delays. To obtain an estimate for the solution, two types of observers are proposed: an asymptotic observer and an asymptotic observer with bounded error. An asymptotic observer is characterized by the fact that its error asymptotically approaches zero. In this case, if the original system has the property of final observability, then the rate of convergence of the estimation error to zero can be set in advance by choosing the characteristic quasi-polynomial of the homogeneous system that describes the behavior of the error. Otherwise, the estimation error is described by an inhomogeneous system, and the rate of its convergence to zero depends not only on the choice of the characteristic quasi-polynomial of the homogeneous system, but also on the behavior of the inhomogeneous part, the dynamics of which depends on the matrices that determine the structure of the output signal. A distinctive feature of an asymptotic observer with bounded error is that its estimation error remains bounded by some constant depending on the observer's initial condition. In this case, the conditions for the existence of such an observer impose weaker requirements on the parameters of the original system in comparison with the conditions for the existence of an asymptotic observer.

Published: June 2023

In this paper, we consider the Cauchy problem for the non-stationary modified Korteweg–de Vries equation with an additional term and a self-consistent source in the case of moving eigenvalues. Also, the evolution of the scattering data of the Dirac operator is obtained, the potential of which is the solution of the loaded modified Korteweg–de Vries equation with a self-consistent source in the class of rapidly decreasing functions. Specific examples are given to illustrate the application of the obtained results.
On monotone approximation of piecewise continuous monotone functions with the help of translations and dilations of the Laplace integral
Authors: Chernov A.V.
Published: June 2023

For piecewise continuous monotone functions defined on a bounded interval $[-b;b]$, a monotone smooth approximation $Q(x)$ of any prescribed accuracy in the metric of the space $\mathbf{C}(\Pi)$ with as small as desired measure of the difference $[-b;b]\setminus\Pi$, $\Pi\subset[-b;b]$, is constructed using translations and dilations of the Laplace function (integral). In fact, this extends to the case of piecewise continuous monotone functions the result (obtained by the author formerly) on arbitrarily exact in the metric of the space $\mathbf{C}[-b;b]$ monotone approximation of continuous monotone functions with the help of translations and dilations of the Laplace integral. Besides, we suggest a new way of approximation in the form of linear combination of translations and dilations of the Laplace integral. Finally, we give and discuss concrete numerical examples of using approximation ways under study for a piecewise constant (stepwise) monotone function and for a piecewise continuous monotone function. Here, we also compare the results obtained for two discussed ways of approximation.

The policy of working from home during the COVID-19 pandemic caused changes in the work environment and job demands that were suspected of causing cyberloafing. This study aims to determine the role of job boredom in mediating the effect of job demands on cyberloafing. Data were collected through online questionnaires to measure cyberloafing, job boredom and job demands from 116 participants who work as administrative staff. Data processing was carried out through regression techniques. The results showed that job demands had a significant effect on cyberloafing (β = 0.427, p = 0.000). After entering job boredom as a mediator, the results showed that the effect of job demands on cyberloafing decreased (β = 0.251, p = 0.004). These results indicate that job boredom can mediate (partially) the effect of job demands on cyberloafing. So, the effect of job demands on cyberloafing is even greater when those demands lead to work boredom. The correlation between demographic data and research variables show that position, working hours and length of using internet have a positive correlation with job demands; age, tenure, and working hours have a negative correlation with job boredom; age and tenure are negatively correlated with cyberloafing.

This research was conducted based on the phenomenon of abusive supervision faced by employees. Abusive supervision experienced by employees, namely verbally and non-verbally. The purpose of this study is to understand the dynamics of emotional regulation in employees who experience abusive supervision. The subjects of this study were three employees who were selected using a purposive sampling technique. This study used a qualitative method with a phenomenological approach. Data were collected through in-depth interviews on the subject and references to journals, books, research results and other data provided for research. The analysis technique used is Interpretative Phenomenological Analysis (IPA). The findings indicated that the process of regulatory dynamics carried out by the three research subjects included 3 (three) phases, namely the assessment phase, the emotional experience phase, and the behavioral response phase. The individual's tendency to develop and comply with standards despite experiencing abusive supervision can be an indication that the individual has good emotional regulation dynamics, while the individual's tendency to be passive is an indication of obstacles in the dynamics of emotional regulation.

Research shows that students with academic grit have better achievement, learning regulation, and resilience abilities than students without academic grit. Even so, research results show that it is still rare to find academic grit in a person. Academic hope is a positive psychological variable that has many benefits to positive educational variables and has been proven to be able to predict academic grit. This study tries to look back at the ability of academic hope to academic grit in middle school students. The participants used in this study were 194 students of SMK-SMAK Makassar. There were two instruments distributed to SMK-SMAK Makassar students, namely the academic hope scale and the academic grit scale which were distributed to research respondents. Tests on the data collected show that academic expectations can provide significant academic grit and make a large effective contribution. There are two aspects of academic expectations, namely pathway and agency. Path analysis as an additional analysis to see the predictive ability of each aspect of academic expectations shows that the path makes a large effective contribution, while the agency makes a small effective contribution. These results show the balance of academic expectations of one's academic grit.
