Published: January 2023

Penelitian ini bertujuan mengeksplorasi  pola asuh yang  mempengaruhi perkembangan bahasa anak usia 25 bulan dan 24 bulan. Prisha Arrang, anak berusia (25 bulan), menjadi subjek penelitian pertama, sedangkan Susanti Limbong sebagai subjek penelitian kedua (24 bulan). Keduanya termasuk dalam anak berusia 2 tahun. Studi ini mengeksplorasi  bagaimana pola pengasuhan kedua anak mempengaruhi fonologi, morfosintaksis, leksikon, dan pragmatik. Metode penelitian yang digunakan adalah observasi, wawancara sederhana dan merekam partisipasi percakapan, kemudian menganalisis data mengkaji komponen fonologis, morfologis, dan sintaksis yang telah disesuaikan usia untuk kedua anak tersebut. Temuan penelitian menunjukkan bahwa gaya pengasuhan orang tua berdampak pada perkembangan bahasa anak. Perkembangan bahasa anak yang diasuh oleh orang tua lebih unggul dari pada yang diasuh oleh pengasuh pembantu. Anak-anak yang mengalami keterlambatan dalam belajar bahasa dipengaruhi oleh pola asuh orang tua yang tidak tepat. Kata-kata yang diperoleh dari pola asuh orang tua (Prisha) [to], [ap ap], [as as], dan [nang nang]. Kata [to] mengacu pada makna to yang berarti itu. Kata [ap] mengacu pada makna hp. Kata [as as] mengacu pada makna cas. Kemudian frasa [nang nang ku] yang merujuk pada     makna masannang masannang aku, yang baerarti senang senang aku. [ap to] yang merujuk pada     makna hp to, yang baerarti hp it. Prisha menguasai sintaksis yang baik untuk anak berusia dua tahun karena ia dapat menggabungkan dua kata menjadi kalimat pendek, seperti [nang ku] dan [ap to]. Sedangkan kata-kata yang diperoleh dari pola asuh pembantu (Susanti) vokal [o],  konsonan [t] dan [k]. Konsonan [o] yang mengandung makna kata io yang berarti iya.  Konsonan [t] membentuk suku kata [ti] yang mengandung makna kata Susanti. Lalu, konsonan [k] digunakan Susanti untuk menyampaikan suku kata [ka] yang mengandung kata boneka.

Published: January 2023

According to the European Commission, education, science, technology, research and innovation are a prerequisite for achieving a sustainable EU economy. EU leaders have agreed to work towards a European Education Area by 2025 to take full advantage of education, training, and culture (EU, 2019). Scientific literacy takes center stage in major reforms in education and is often presented as a key goal of science education. This is due to the idea that scientific literacy could be a prerequisite for the economic survival and technological development of the society, at least if judged by the research based on correlations between large-scale international testing results and country’s economic prosperity level (Hanushek & Woessmann, 2010). Chemical literacy presents a significant constituent part of scientific literacy, given that the use of various chemicals plays a vital role in our daily lives whether we are talking about food, medicine, clothing or climate change.

Authors: Aylar Çankaya Ebru , Yıldız Esengül , Cengiz Cemre
Published: January 2023

An integer-based mathematical game was the main subject of the study. The aim of this study was to analyse the mathematical content of the game which was developed by a fourth-grade student called Esin, and to examine the intuitive learning that develops through this game. The game was based on the addition of the positive or negative numbers won in each round. The integer is regarded as an abstract topic and is taught in secondary school. It is also regarded as a topic that students have difficulty in learning. However, in the case examined by this research, a fourth grader created an integer addition game using her own intuitive understandings and played it with three of her friends. This research was a case study focusing on the analysis of the game. The study group of the research was Esin and her three friends who played the game. Data was gathered in two stages. In the first stage Esin played the game with researchers and in the second stage Esin and her friends played the game together. All the games were recorded, and the observation form was used to record data. Descriptive analysis, which consists of two codes (cardinal or ordinal meaning), was carried out in data analysis. As a result of the study, it was seen that, Esin had defined negative and positive numbers over the idea of win / lose. Students were able to use both the cardinal and ordinal meanings of the number while playing the game. Cardinal meaning was usually established through the neutralization relation. Ordinal meaning was mostly used over positioning the number relative to zero. This research contributes to the literature on students' learning of integers at an early age.

Authors: Alkış Küçükaydın Menşure , Akkanat Çiğdem
Published: January 2023

Computational thinking is recognized as a vital skill related to problem-solving in technological and non-technological fields. The existence of different sub-domains related to this skill has been pointed out. Therefore, there is a need for tools that measure these different sub-domains. Because of its structure that includes different skills, computational thinking has a structure different from that of the tools used to measure academic skills. Moreover, no special programming knowledge is required for tools that measure this ability. In order to measure this skill in younger age groups, it is possible to apply the measurement tool without adult support. At this point, it is aimed to reveal the computational thinking skills of Turkish children by adapting a test developed for the 7-9 age groups into Turkish. For this purpose, an adaptation research study was performed for TechCheck-2 developed by Relkin et al. (2020). In the study, a total of 372 primary school students studying in Ankara were contacted. Item and test analyses were performed on the data obtained as a result of the application of the test. The distinctiveness and difficulty values of the items making up the test and Kuder Richardson-20 scores were calculated. At the end of the analyses, it was seen that the test could be used as a valid and reliable measurement tool for Turkish children.

Published: January 2023

The effect of toxicity on satisfaction with life at school affects many variables. As parts of school culture, satisfaction and toxicity are related concepts. This study aims to determine the predictive effect of toxicity on satisfaction with life at school. In Turkey, no study has been found to be conducted about the relationship between organizational toxicity and satisfaction with life. Method of the research: This was a descriptive study based on the correlational survey model. In this study, it was supposed to determine the effects of teachers’ demographic characteristics (gender, alma mater, professional seniority, and number of teachers in the school) and toxicity perceptions on satisfaction with life. The study group consisted of 1600 teachers working at 54 secondary schools in Sivas city center. Based on the calculation made, a sample of 223 teachers representing the population was created. The dependent variable of the study was teachers' satisfaction with life. Stepwise regression was used as a multiple regression analysis technique. In this regression analysis, a linear structure of the relationship between one dependent and more than one independent variable was tested. The results showed that the toxicity avoidance behaviors of teachers positively affected their perceptions of satisfaction with life. It was teachers' displaying conflict behaviors (β= -,226) regarding toxicity. There was a decrease in the satisfaction with life of teachers who ventured conflict. Likewise, there was a negative effect (β= -184) between the level of narcissistic behavior in the organizational environment and the level of satisfaction with life. The satisfaction with life levels of teachers who thought that narcissistic behaviors were exhibited in the organizational environment decreased. A positive relationship was found between the fourth ranked variable resistance (β= ,149) and satisfaction with life. Teachers' resistance to painful toxic situations increased their level of satisfaction with life.

Isolation, Identification and Determination of Saccharomyces cerevisiae Yeast Species from The Wines Made by Spontaneous Fermentation Using Papazkarası Grapes from Thrace Region
Authors: ERSEÇ Çağrı , DEMİRCİ Ahmet Şükrü
Published: January 2023

Especially in large-scale commercial wine production, fermentation is usually carried out by using the species of Saccharomyces cerevisiae yeast cultures. Standard wine yeast starter cultures are brought from abroad and used in industrial winemaking in our country. Thus, in course of time, the wines of all producers began to show similar properties. Today, studies focus on terroir wines production with local characteristics by using the countries' own local wine yeasts as a starter. Within the scope of this study Papazkarası grapes were collected from 4 vineyards with different characteristics, such as viticulture practices, microclimatic conditions and locations in the borders of Edirne and Kırklareli. In addition, the grapes were also collected from the vineyard in Tekirdağ Viticulture Research Institute. Spontaneous fermentation was done by crushing the collected grapes in the laboratory. At the end of the fermentation, yeast isolations were made from the musts to YPD medium and a total of 66 isolates were obtained as a result of purification. Fermentation rate, H2S production amount, growth at high temperature, growth at high sugar concentration, resistance to high ethanol, ability to grow at low pH values, resistance to SO2, and volatile acid analysis were done to determine whether they meet the technological requirements for basic winemaking, together with two commercial wine yeasts. DNA sequencing analyzes were made by selecting 15 of the isolates that were found to have the necessary characteristics and it was determined that they belonged to the Saccharomyces cerevisiae species. DNA fingerprinting analysis was performed using delta 12-21 primers to determine the strain differences of the isolates determined to belong to the same species. By DNA fingerprint analysis, it was determined that 9 out of 15 isolates were different strains.

Published: January 2023

The environmental conditions determining the distribution of the southern eagle ray Myliobatis tenuicaudatus are mostly unknown. We tracked 40 southern eagle rays using a network of 28 acoustic receivers deployed in Coffin Bay and a second array of 6 receivers deployed along the Fleurieu Peninsula, both in South Australia, to investigate the spatiotemporal changes in space use and residency and the influence of biotic (disc width, sex) and abiotic (water temperature, salinity, tides, moon illumination, time of day) factors. We also assessed the efficacy of a small sanctuary zone to reduce anthropogenic pressures. Tagged southern eagle rays in Coffin Bay were semi-permanent residents (residency index ~ 0.35), with a seasonal exodus from late autumn to spring, high residency from mid-spring to mid-autumn, and selection of Kellidie Bay (located within Coffin Bay). Most (67%) rays were detected in the Kellidie Bay Sanctuary Zone, but spent <15% of their time in Coffin Bay within the sanctuary. Individual variation in the amount of time spent in the Kellidie Bay Sanctuary Zone was high, ranging 0-42%. In contrast, tagged southern eagle rays along the Fleurieu Peninsula had high site fidelity throughout the year (residency index ~ 85%). Our study provides new information on space use and movement patterns of southern eagle rays, highlighting that intraspecific variation should be accounted for in future management considerations.
Spatiotemporal patterns in the ecological community of the nearshore Mid-Atlantic Bight
Authors: Gartland J , Gaichas SK , Latour RJ
Published: January 2023

Recognition of the need for a more holistic, ecosystem approach to the assessment and management of living marine resources has renewed interest in quantitative community ecology and fueled efforts to develop ecosystem metrics to gain insight into system status. This investigation utilized 12 years (2008 to 2019) of fisheries-independent bottom trawl survey data to quantify and synthesize the spatiotemporal patterns of species assemblages inhabiting the nearshore Mid-Atlantic Bight (MAB). Assemblages were delineated by ecomorphotype (EMT), and all species collected by the survey were allocated among 9 EMTs: demersal fishes; pelagic fishes; flatfishes; skates; rays; dogfishes; other sharks; cephalopods; and benthic arthropods. Annual time series and seasonal spatial distributions of relative aggregate biomass were quantified for each EMT using delta-generalized additive models. Dynamic factor analysis (DFA) revealed that the information content of the 9 annual time series was effectively summarized by 3 common trends, and DFA model fits to each EMT time series represented a new suite of ecosystem indicators for this system. Mean sea surface temperature during winter in the MAB was included in the selected DFA model, suggesting that winter environmental conditions influence the structure of this system at an annual scale. Principal component analysis uncovered a north-to-south gradient in the seasonal spatial distributions of these EMTs and identified a distinct area of elevated biomass for several assemblages along the south shore of Long Island, NY. Taken together, these results characterize the community structure of the nearshore MAB and yield requisite information to support ongoing ecosystem-scale assessment and management activities for this region.
Approaches to Estimate the Magnitude of Phonon Scattering via Point Defects in Mo(Se1-xTex)2 Thermoelectric Alloys

Published: January 2023

One of the most popular routes used to improve the thermoelectric performance of materials is to suppress their lattice thermal conductivities. Thermoelectric performance is characterized by a figure-of-merit zT, which is defined as σS2T/(κe + κl), where the σ, S, T, κe, and κl are the electrical conductivity, Seebeck coefficient, temperature (in Kelvin), electronic thermal conductivity, and the lattice thermal conductivity, respectively. Among the variables in zT, the κl is the only variable that is independent of all other variables. In other words, reduction in κl guarantees zT improvement. Therefore, several different strategies to decrease κl have been introduced and implemented. Among the many κl reduction strategies, introducing point defects in the material by forming an alloy is particularly effective. Here, phonon scattering due to point defects in Mo(Se1-xTex)2 (x = 0.0, 0.25, 0.50, 0.75, 1.0) was studied using both the Debye-Callaway (DC) model and Callaway-von Baeyer (CvB) model. The advantages and disadvantages of using DC or CvB models are thoroughly discussed. When analyzing the effect of phonon scattering due to point defects, the CvB model is simpler and gives more information about the details of phonon scattering.

Authors: A.S. Mohite , A.V. Dorlikar
Published: January 2023

Azadirachtin is a tetranortriterpenoid derived from the neem tree Azadirachta indica A. juss. Azadirachtin has attracted worldwide attention as promising feeding deterrent, insect growth disruptor and sterilent. Azadirachtin based pesticides become very much popular because of its biodegradability and least toxicity to non- target organisms. It has now been promoted as an alternative insecticide in integrated pest management programmes. Azadirachtin has an ability to modify or suppress haemolymph ecdysteroid and juvenile hormone titres through inhibition of the secretion of brain peptides prothoracicotropic hormone and allatotropic hormone, which are responsible for inducing the synthesis and release of ecdysone from the prothoracic gland and juvenile hormone from corpora allata, respectively. Blocking the synthesis and release of ecdysone and juvenile hormone leading to disruption of coordination of moulting process. Furthermore, this compound is known to cause degenerative changes in the cells of insect endocrine glands. This review focuses on growth regulating effects of natural pesticide, azadirachtin from neem tree (Azadirachta indica A. Juss) on insects.

Published: January 2023

Communication plays an important role in society. This can be seen in the amount of information that is spread, such as information in the form of sound, images, and videos. But communicating is not always easy. Due to the large number of sounds emitted from different sources, other sounds will be disturbed. The interference caused by noise can distort the information signal, leading a sine wave to integrate a minor noise signal. As a result, the receiver cannot differentiate the actual information signal and the added noise. This study proposed a noise-reduction system by analyzing the effect of the number of filter orders on the noise canceler system. The information signal will be processed using the STM32F4 noise canceller system, which will then be filtered using an adaptive filter with a Finite Impulse Response (FIR) structure and the Least Mean Square (LMS) algorithm. The test results show that the best SNR value is obtained at Order 40 of 5.3671 dB at a sound duration of 14 seconds, while the best PSNR value is obtained at Order 40 of 21.3557 at a sound duration of 9 seconds, and the higher the filter order value, the smaller the MSE value.

Published: January 2023

Paper is one type of archive that is stored in the Archives Building. Maintenance of paper type archives needs to be considered to avoid mold growth and discoloration due to cigarette smoke. Therefore, a telecontrolling device is needed that can maintain a stable air humidity at 30% - 55% and a temperature of 15 °C - 22 °C. However, devices with a frequency of 2.4 GHz should not be used simultaneously in the same area because it will cause interference that can reduce performance. In this study, a temperature tele controlling system and smoke detection in the archive warehouse were made using hybrid visible light communication technology to improve data transmission performance. The system consists of 1 transmitter node connected to DHT 22, MQ 2, LED laser and WiFi network, as well as 2 receiver nodes to control the fan and water pump. The data from the receiver will be passed through the photodiode and then processed by the microcontroller. If the temperature value reaches the threshold, the receiver node will send a command so that the fan will turn on automatically, then if the smoke value reaches the threshold, the water pump will turn on automatically. The temperature and smoke values ??can be monitored in real time through the android application. The test results show that the use of hybrid visible light communication technology in the tele controlling system makes the delivery performance better.

Cluster housing is chosen by many people because of the security system is uses one gate system. However, the housing portal system that is often encountered still uses human labor and guest data recording is also still done manually.  It often happens that the housing portal is always open, so that residents and non-residents can enter and exit the housing freely. Based on the existing problems, this research proposes an innovation, namely "Prototype of Cluster Housing Portal Security System Using Fingerprint and One Time Password Based on Internet of Things". Fingerprint is used for portal access by residents, while One Time Password (OTP) is used by guests to access the portal. The OTP is made through the citizen's website. The OTP will later be sent by residents to guests, so they can access the portal without having to have a security guard. All portal access data and guest data can be monitored through the security officer's website. The test parameters in this study are the accuracy of the fingerprint sensor, the suitability of the OTP code, the accuracy of the proximity sensor E18-D80NK, Quality of services (QoS), and the overall system test.

Microstrip antennas have a weakness, namely narrow bandwidth, therefore a modification is needed using the DGS (Defected Ground Structure) method in the form of a dumbbell circle head. The allocation of the Wi-Fi working frequency that is often used in the community is 2.4 GHz in accordance with the IEEE 802.11 protocol standard. This study discusses the result and the effect of the performance of an 2x4-element microstrip array antenna using DGS. This DGS is placed on the ground plane and uses a PCB with an epoxy fiberglass substrate material which has a dielectric constant of 4.58. The result of this research is an external device, namely a microstrip antenna that can increase data transfer capacity and work on a Wi-Fi frequency of 2.4 GHz. This research is in accordance with the antenna test parameters, which have a return loss value of -22.7 dB and VSWR 1.15. 1. The results of testing the bandwidth of the hexagonal 2x4 element microstrip patch antenna with a defected ground structure of 34 MHz. The radiation pattern of the hexagonal 2x4 element microstrip patch antenna using DGS is directional. The results of the power level implementation of a hexagonal microstrip patch antenna arranged in a 2x4 array using a DGS dBm can increase power level by 7 dBm.

An Islamic educational facility called a pesantren houses students, or santri, in dormitories. One of the biggest Islamic boarding schools in Jombang is called Darul 'Ulum. Students are expected to participate in early recitation activities, are forbidden from smoking, are forbidden from visiting the student rooms without the coach's permission, and are forbidden from entering the guest rooms. This research used a case study of a high school dormitory as an example. For proper monitoring of student breaches, a high number of students demand more efficient supervision. Based on these issues, a monitoring system is required that may alert the hostel supervisor to infractions in real-time, allowing them to take fast action against violators and impose sanctions in line with the seriousness of the offenses. This study uses an android application monitoring of students. According to the results of testing violations of students who smoke in the room using the MQ-2 sensor with 10 test trials, a 100% success rate is obtained in detecting cigarette smoke, and testing violations of students who are still in the room at the time of the early Koran reading with using a PIR sensor with 10 test trials, the success rate was 100% in detecting the presence of students. Both the RFID sensor test and the fingerprint sensor test resulted in delays of 1.59 seconds and 3.01 seconds, respectively, with 100% success rates.

The electrical installation structure on autobuses is generally still based on the old concept that relies on the fuse, where the fuse is the only safety as well as an indicator of the presence or absence of electrical power supply to several electrical devices contained in the autobus. For conditions where there is a short circuit on the line to the electrical load, the electrical equipment on the autobus cannot be operated again. With the problem in the electrical system on the autobus, a monitoring system for controlling the power used on the autobus vehicle was created automatically based on wireless. In this study, the system created using Arduino Uno is functioned as a server node. Then there is a sensor node which will later function to receive incoming data from the Ina219 sensor, then sent using wireless communication to the server node. Then on the server node, all data will be monitored via the LCD display and notification LED, then if there is excessive use the system will turn off the relay where the point is using excess power. From the test results, the sensor node is able to send data from the sensor node readings. Then it is sent to the Node Server and the results obtained are 2% for packet loss. The delay value is 0.29s for the highest result.

Cooking oil that is used repeatedly is called cooking oil. Due to the very high price of cooking oil, people still use used cooking oil for daily cooking, even though it is very dangerous for health and can cause a number of diseases, such as stroke, coronary heart disease, hypertension, and cancer. Parameters that are quite important to determine the quality of used cooking oil based on Indonesian quality standards of cooking oil are color parameters, pH, free fatty acid levels and turbidity. These four parameters need to be emphasized so that people can know and control the quality of used cooking oil that is suitable for reuse. In this research, a tool is made that can determine the quality of used cooking oil based on the parameters of color, pH, free fatty acid content and turbidity. The detector is equipped with a TCS3200 sensor to detect color, a pH sensor to detect pH, a conductivity sensor to detect free fatty acid levels and a turbidity sensor to detect turbidity in used cooking oil. For data transmission, the ESP32 module is used and the output data can be viewed and monitored via a 16x2 LCD and a website on a smartphone or computer. The system created has a good quality of information delivery and successful data transmission when testing delay and packet loss. The success rate of sending data from ESP32 to the Webserver is 92.4% and the average delay in sending data is 0.0025 ms.

Many types of antennas can be used for digital TV receivers; in this article we try to design a double biquad antenna. This is due to a simple form, easy to make, a wide beamwidth. In designing a digital TV receiver for the Malang area, an STB device is needed, so that analog TV can still receive digital TV broadcasts. In this study, the antenna is made of copper wire, each side length: ¼ ? , with a working frequency: 650 MHz. In order to match the impedance of the 75? coaxial cable with the antenna, a  balun 4:1 is required. The research place is in the Polinema Telecommunications laboratory. The test results show that the lowest return loss (RL) occurs at a frequency of F=605 MHz, namely RL: -17.8 dB, for a frequency of F=650 MHz, the magnitude of RL: -11.3 dB. The large VSWR antenna at the working frequency F: 650 MHz is 1.46. So that it can be said that it has fulfilled the antenna parameters, namely VSWR < 2. It means that there is a power loss of less than 10%. The largest antenna gain occurs at a frequency: 400 MHz namely: 14.85 dB,. While the average gain of the antenna is 2.21 dB. The antenna radiation pattern is omni directional. The double biquad antenna is very good for use as a digital TV receiver for the Greater Malang area, either without using a reflector or with a reflector.
