ABSTRACT The phenomenon of the COVID-19 pandemic that began to spread in 2020 made various changes to aspects of life. The drastic changes in life patterns can affect the subjective well-being level of individuals. The purpose of this study was to determine the influence between gratitude and subjective well-being of Makassar City residents during the COVID-19 pandemic. This study uses quantitative methods. The research subjects were residents of Makassar City aged 18-40 years (n=157). The sampling technique used is accidental sampling. Data was collected through the distribution of three psychological scales that were filled through online form. The scales are: The Gratitude Questionnaire-Six Item Form (GQ-6), Satisfaction with Life Scale (SWLS), and the Scale of Positive and Negative Experience (SPANE). The collected data were analyzed using non-linear regression analysis. The results of the study reveal that there is a significant contribution between the gratitude variable toward subjective well-being level with a significance value 0.000 (sig <0.05), but the contribution tends to be weak because the coefficient of determination (R Square) is only 0.234. This means that the contribution of gratitude is only 23.4% to be able to predict the subjective well-being of Makassar City residents during the COVID-19 pandemic.  ABSTRAKFenomena pandemi COVID-19 yang mulai merebak di tahun 2020 membuat berbagai perubahan pada aspek-aspek kehidupan. Adanya perubahan pola kehidupan yang drastis serta kondisi kehidupan yang tidak dapat berjalan normal dapat memengaruhi tingkat kesejahteraan subjektif pada individu.Tujuan penelitian ini adalah untuk mengetahui pengaruh antara kebersyukuran dengan kesejahteraan subjektif warga Kota Makassar pada masa pandemic COVID-19. Penelitian ini menggunakan metode kuantitatif. Subjek penelitian adalah warga Kota Makassar yang berusia 18-40 tahun (n=157). Teknik sampling yang digunakan adalah accidental sampling. Pengumpulan data dilakukan melalui penyebaran tiga skala psikologi yang diisi secara daring, yaitu: The Gratitude Questionnaire-Six Item Form (GQ-6),  Satisfaction with Life Scale (SWLS), dan Scale of Positive and Negative Experience (SPANE). Data yang telah terkumpul dianalisa dengan menggunakan teknik analisis regresi non linear. Hasil penelitian mengungkap bahwa terdapat kontribusi yang signifikan antara variabel kebersyukuran terhadap tingkat kesejahteraan subjektif dengan nilai signifikansi 0,000 (sig<0,05), namun kontribusinya cenderung lemah karena koefisien determinasi (R Square) hanya senilai 0,234.

The mechanism of self-assembly by short-chain peptides (oligopeptides) – the process by which their molecules spontaneously form an ordered structure – has received much attention recently. Self-assembling phenylalanine oligopeptides have been of particular interest due to their potential as an effective aid in the design of new functional materials. This paper considers the results of an SPM study on the ability of L-alanyl-L-phenylalanine to self-assemble into a thin film under the action of methanol vapor. The micro- and nanostructures that develop on the surface of amorphous films of this dipeptide were characterized. A method for monitoring the state of the surface of dipeptide films using atomic force spectroscopy was proposed. The results obtained contribute to the development of approaches for the controlled self-assembly of oligopeptides used to produce new biocompatible materials and environmentally friendly micro- and nanodevices that would help solve various problems in the medical, environmental, and energy fields.

To obtain reliable results in the quantitative determination of rare earth elements (REE) by atomic emission spectroscopy, it is particularly important to take into account the matrix effects of the macrocomponents contained in the analyzed solutions. Analytes obtained by liquid-phase and autoclave opening of geological samples of REE ores and minerals contain significant amounts of strong mineral acids used as reagents and such macrocomponents of the samples as aluminum (aluminosilicates) and phosphorus (phosphates in apatites). Here, we studied the effects of hydrochloric, nitric, sulfuric, and orthophosphoric acids and aluminum on the relative intensity of the ion analytical lines of La, Ce, Nd, Sm, Gd, Tb, Er, and Yb in atomic emission spectroscopy of the microwave-induced plasma (AES MIP). With an increase in the acid concentration from 0 to 1 mol/L, the relative intensity of the spectral lines of all investigated REE decreased monotonically by 10–20%. The depressing effect of aluminum, which is due to a decrease in the degree of ionization of REE atoms, was much stronger and reached 70%. It was shown that the AES MIP method is not inferior to atomic emission spectroscopy of inductively coupled argon plasma in terms of the detection limits of lanthanum, cerium, gadolinium, and erbium.

The Au–Bi binary system electrodeposited on the surface of a glassy carbon electrode exhibits catalytic activity during the electrooxidation of phenylephrine, paracetamol, and caffeine that enhances the peak currents and decreases overvoltage in the oxidation of organic compounds. The potential difference between the peaks of oxidation on the modified electrode is 400 mV for phenylephrine and paracetamol and 300 mV for phenylephrine and caffeine, respectively. The possibility of simultaneous voltammetric determination of phenylephrine, paracetamol, and caffeine on the glassy carbon electrode modified by the Au–Bi binary system was established. The calibration curve is linear in the concentration range from 5·10–6 to 5·10–3 M. The developed method was tested in the analysis of combined drugs.
STUDENT-CENTERED DISTANCE LEARNING IN COMPLICATED CONDITIONS (PANDEMIC COVID-19, MARITAL STATE IN UKRAINE)
Authors: Starosta Volodymyr
Published: May 2023

The article updates the problems of student-centered learning, which is the core of modern higher education. The specificity arises during the implementation of student-centered distance learning in the complicated conditions of the global Covid-19 pandemic (2020-2021) and martial law in Ukraine (2022). The author included 1071, 443, and 834 university students in the anonymous online survey in 2020, 2021, and 2022, respectively. The computer program IBM SPSS Statistics 23 was used to process the results of the student survey. The obtained results indicate that the following means of distance learning were most widespread at the university at the beginning of the pandemic (listed in order of decreasing number of used educational disciplines, 2020): Moodle, Email, messengers. Google Meet, Google Classroom, Zoom are gaining priority as distance learning tools for students in 2021, 2022. The majority of students (about 70%) easily register in the Moodle system, but about 20% experience minor and about 10% significant difficulties. Some students express dissatisfaction with the quality of Internet connection (about 25-29%), their own technical support (about 17-20%), psychological comfort (about 22-27%). The calculation of the t-test indicates the absence of a statistically significant difference (p≤0.05) for independent samples of neighboring years during distance learning according to the following characteristics: ease/difficulty of registering students in Moodle (2020-2021, 2021-2022), psychological comfort (2020-2021), satisfaction with the quality of Internet connection (2020-2021, 2021-2022) and the quality of own technical support (2021-2022); in other cases of comparison, a statistically significant difference is observed. We used computer-oriented re-testing in Moodle, taking into account the complicated conditions of distance learning in Ukraine (2020-2022). This approach helps to improve the learning results of bachelor and master students by almost 16% and 13-17% for training, as well as by 4% and 3-20% for modular testing, respectively. We believe that the positive results of re-testing in Moodle should be taken into account and disseminated in the practice of higher education.

Authors: Rachminawati Rachminawati , Kebingin Stevanus Aditya
Published: May 2023

The right to education for refugees, particularly child refugees, is seen as a fundamental right. According to data from the United Nations High Commissioner for Refugees (UNHCR), nearly half of all child refugees have had no official or informal schooling. The realization of the right to education in the Association of Southeast Asian Nations (ASEAN) region presents unique problems, particularly for refugee children from Myanmar's Rakhine State. The ASEAN Ways are often being claimed as the main hindrance in tackling the problem. However, to some extent, it has proven in maintaining stability in the ASEAN region. This paper examines how ASEAN Ways approach fulfilling the right to education in terms of policy and implementation through the Bali Process consensus and relevant ASEAN organs such as the ASEAN Intergovernmental Commission on Human Rights (AICHR) and ASEAN organizations in education cooperation (SEAMEO). The legal and qualitative research methods have been used in this study. As the outcome, this study shows that the ASEAN Ways approach in protecting the right to education especially for refugee children from Rakhine states provides a stronger foundation for fulfilling their rights in each of ASEAN destination countries such as Indonesia, Malaysia, Philippines, and Thailand. Although national laws and regulations differ from one state to the next, it will promote the fulfillment of the right to education while sustaining stability in the ASEAN region with support from ASEAN as a regional organization via reinforcing the principles of ASEAN Ways.

Through Article 2 paragraph (1) of Law of the Republic of Indonesia Number 1 of 2023 concerning the Criminal Code (National Criminal Code), customary law opportunities are open to existing through the prerequisites contained in the Explanation to Article 2 paragraph (1). For this reason, this study aims to determine the opportunities for the existence of Gorontalo customary law through the prerequisites contained in the Explanation of Article 2 paragraph (1) of the National Criminal Code. This research uses normative legal research methods with a statutory approach and conceptual approach and uses primary, secondary and tertiary legal materials. The legal material is then analyzed qualitatively using grammatical, systematic, and historical interpretations. The results showed that Gorontalo customary law exists through the presence of several regional regulations, including (1) Gorontalo Provincial Regulation Number 2 of 2016 concerning the Implementation of Customary Institutions; (2) Gorontalo Mayor Regulation Number 10 of 2020 concerning the Implementation of the Dulohupa Customary Institution of Gorontalo City; and (3) Regional Regulation of Bone Bolango Regency Number 8 of 2020 concerning the Implementation of Customary Institutions. Furthermore, through regulations at the regional level, Gorontalo customary law is also present through concrete events such as the management of customary institutions carried out periodically. Based on this, the regulation of concrete norms related to acts prohibited under living law in regional regulations as required by the Explanation to Article 2 paragraph (1) of the National Criminal Code will have a very large opportunity.

Dengan disahkannya  UU No. 11 tahun 2021 tentang Perubahan UU No. 16 Tahun 2004 tentang Kejaksaan, pada akhirnya menimbulkan polemic khususnya terkait ketentuan Pasal 30C huruf h terkait kewenangan Jaksa Penuntut Umum dalam mengajukan Peninjauan Kembali. Pendapat kontra berpendapat bahwa pembentuk UU kurang memahami norma-norma dalam peraturan perundang-undangan yang ada. Disisi lain, Putusan MK No.33/PUU-XIV/2016 bersifat final dan mengikat bagi siapapun termasuk lembaga kejaksaan yang seharusnya taat terhadap putusan Mahkamah Konstitusi. Dilain pihak, berdasarkan penelitian atas kewenangan Jaksa Penuntut Umum mengajukan Peninjauan Kembali berpendapat hal ini dapat dimaknai sebagai tugas dan tanggung jawab kejaksaan mewakili kepentingan negara serta “keadilan”  bagi korban serta sebagai upaya koreksi dan perbaikan dalam mewujudkan keadilan. Norma itu harus menempatkan posisi Jaksa secara proporsional dan seimbang dalam upaya hukum pengajuan Peninjauan Kembali. Dengan lahirnya UU Kejaksaan aquo justru dianggap lebih memberikan kepastian hukum atas kewenangan Jaksa Penuntut Umum dalam mengajukan Peninjauan Kembali.

The nutrients and chemical contents of Persea americana, Dacryodes edulis, and Canarium scheinfurthi fruits and partial characterization of their seed oils were carried out to ascertain their nutritional benefits. The fruit pulps were analyzed for chemical (proximate) composition, amino acids profile, vitamins, and phytochemical and anti-nutritional compositions. Oils were extracted from the fruit seeds and the physico-chemical properties of the seed oils were determined according to the standard protocols. The results showed that the fruit pulps contained an abundance of macro- and micro-nutrients which varied significantly (p < 0.05) among the varieties with low anti-nutrients. The essential amino acid contents were high and varied significantly (p < 0.05) among the varieties. Glutamic acid, followed by aspartic acid had the highest concentration of the amino acids, while the concentrations of methionine and cysteine were low in all the varieties. The results also revealed high essential amino acids score values, above 100% for isoleucine and total aromatic amino acids. The physicochemical properties of the fruit oils showed that the oils were edible (low acid value) and may have industrial potential due to their low peroxide, iodine, and saponification values. Overall, the results showed that the pears are nutritionally rich and could serve dietetic and industrial purposes.

Penelitian ini bertujuan membuat pemodelan untuk diagnosis repeat breeding (RB) pada sapi aceh berdasarkan intensitas estrus, profil hormonal, profil biokimia darah, dan jumlah infeksi bakteri pada saluran uterus. Hewan yang digunakan pada penelitian ini adalah 16 ekor sapi aceh yang terdiri atas 7 ekor sapi aceh fertil dan 9 ekor sapi aceh RB, yang berumur 3-8 tahun dengan skor kondisi tubuh (BCS) 3-4. Seluruh sapi aceh fertil dan RB dilakukan sinkronisasi estrus menggunakan hormon PGF2α dengan pola penyuntikan ganda dengan interval 11 hari. Setelah penyuntikan PGF2α, intensitas estrus diamati 3 kali sehari yakni pada pukul 08.00, 12.00, dan 16.00 WIB, masing-masing pengamatan selama 20 menit. Koleksi serum dilakukan pada pagi hari (jam 07.00-09.00 WIB). Koleksi serum dilakukan untuk pemeriksaan kadar hormon estradiol dan progesteron menggunakan teknik enzyme linked immunosorbent assay (ELISA). Selain itu, sampel darah juga digunakan untuk pemeriksaan profil biokimia darah. Koleksi sampel bakteri dilakukan dengan metode swab uterus. Hasil pemodelan diagnosis RB pada sapi aceh diperoleh model matematis regresi linear sebagai berikut : Y= a + bX1 + bX2 .............+ bX11S/C = -5.28 + 1,27X1 - 0,69X2 - 0,99X3 - 0,23X4 + 2,28X5 – 0,53X6 + 0,71X7 - 0,29X8 + 0,09X9 + 3,04X10 Berdasarkan hasil dari pemodelan diagnosis RB pada sapi aceh menunjukkan bahwa penyebab utama RB pada sapi aceh adalah infeksi bakteri pada uterus yang kemungkinan mengakibatkan sapi tersebut mengalami stres yang ditandai dengan tingginya kadar glukosa dalam darah. Selain itu, RB pada sapi aceh juga dipengaruhi oleh ketidakseimbangan nutrisi dan hormonal yang mengakibatkan intensitas estrus menjadi rendah.

This study aims to determine whether the market reacts to untimely events. This study uses quantitative research methods with the selection of samples in this study using a purposive sampling technique. The results of the study show that the market reacts significantly to the untimely submission of issuer's financial reports. This is indicated by the significant difference in the abnormal returns on stock of issuers who are late, on time and submit their financial reports early. The results of the post hoc test with LSD show that earlier submission of financial reports gets the best market response from investors, or in other words has the highest abnormal returns. The limitations contained in the results of this study are based on a relatively small number of data sets and short observation times (only two years). As for suggestions that can be put forward, namely, 1) for investors who will buy shares, it is better to choose shares from issuers that historically have often or always submitted their financial reports earlier than Bapepam's provisions. This is because the shares of these issuers tend to be more able to provide high abnormal returns to shareholders. 2) For other researchers who are interested in conducting a review of this research, they should be able to carry out development steps in such a way that research results are better and more comprehensive. This development step can be carried out, for example, by adding observation time

Xanthone compounds in the ethanol extract of mangosteen peel have antibacterial activity against both pathogenic and beneficial bacteria. The purpose of this study was to examine the effect of various formulations of ethanol extract of mangosteen peel and maltodextrin from palm starch on Salmonella thypimurium and Lactobacillus acidophilus. This research was conducted by culturing the bacterial cultures of S. thypimurium and L. acidophilus on nutrient agar (NA) media in petri dishes according to the Kirby-Bauer method. The NA media that had been made in the petri dish was then made wells to test each treatment as much as 10 µL/disk at various concentrations (100, 75 and 50%). The formulations tested in this study consisted of: T1 (30% ethanol extract of mangosteen peel + 70% maltodextrin), T2 (40% ethanol extract of mangosteen peel + 60% maltodextrin), T3 (50% ethanol extract of mangosteen peel + 50% % maltodextrin), T4 (60% ethanol extract of mangosteen peel + 40% maltodextrin), T5 (70% ethanol extract of mangosteen peel + 30% maltodextrin), T6 (ethanol extract of mangosteen peel only), T7 (maltodextrin only), T8 (positive control containing 100 ppm bacitracin) and T9 (negative control/no treatment). The results of each sample were observed by measuring the sample inhibition zone on the growth medium that had been prepared.

Most of the crops are watered through traditional methods of irrigation, which leads to wastage of water. The Crop Water Requirement (CWR) is necessary to design the irrigation system, which is the total quantity of water required for the crop from sowing to harvest.Optimization of water applied to the crop is essential as the yields of the crop are adversely affected either by excess or deficit water supply. CROPWAT 8.0 requires meteorological data as input such as maximum and minimum temperatures, wind speed, relative humidity, and sunshine hours. The soil and crop data were also given as input for calculating the CWR of sweet corn. The meteorological data of the past ten years was collected from the meteorological observatory, which is located at Agricultural College Farm, Bapatla. The average values of the above-said data were calculated for ten years (2012-2021) to estimate the crop water requirement using CROPWAT 8.0. The crop water requirement was estimated as 332 mm using the CROPWAT 8.0 model. It was found to be minimal in the initial stages (15.60 mm/dec) and found to be maximum in the middle stages (64.80 mm/dec), and again at harvesting stage, it started declining (16.70 mm/dec). CROPWAT 8.0 model gives more accurate amount of water needed for the crop, which in turn helps the crop growers to design the appropriate irrigation scheduling.

The study revealed that the expenditure on weeding in onion cultivation was six per cent higher in manually weeded farms than herbicide applied farms. The cost of weeding for manually weeded farm was Rs. 19,729/ha (15.15 per cent) whereas, it was Rs. 11,145/ha (9.44 per cent) in herbicide applied farms. The net returns (returns over cost C3 ) were Rs.1, 93,715/ ha for herbicide applied farms and Rs.1, 28,598/ha for manually weeded farms. The cost of production (per kg) was Rs.7.70 in manually weeded farms and Rs.5.98 per kg of onion in herbicide applied farms. Hence, per ha cost of cultivation in manually weeded farms was higher than herbicide applied farms. The partial budgeting analysis had revealed that an additional return of Rs. 70,982 /ha would be obtained with the use of herbicides in onion cultivation. The average yield obtained in manually weeded farms was lesser than (3, 874 kg/ ha) the yield obtained in herbicide applied conditions. The average prices, gross return, as well as the net return were remunerative and higher to farmers under herbicide applied farms than in manually weeded farms.

Experiments were conducted to develop suitable Melia dubia based agroforestry models for higher productivity in Tamil Nadu. Greengram, blackgram, cowpea, bhendi, small onion, groundnut, sesame, brinjal and chillies were intercropped in 10 months old Melia dubia. Results revealed that the growth and yield of annual crops were found to be reduced under intercrop compared to pure crop, while the volume of trees improved when planted along with intercrops. Among the crops, blackgram (760 kg ha-1 ) was the most affected and brinjal (8700 kg ha-1 ) was the least affected. Growth of M. dubia was also found to be influenced due to intercropping; the lowest in seasame (11.56 m3 ha-1 ) and the highest in blackgram (19.63 m3 ha-1 ). However, the benefit: cost ratio was the highest for brinjal (4.30:1) and the lowest for small onion (2.10:1) due to the higher productivity in brinjal.

Effective pest control can be achieved, if pesticides are properly applied at correct rate, at right time and on the target by appropriate equipment. The spray with conventional sprayer does not reach the bottom of the plant canopy and also the upper and lower side of leaves in required quantity. In view of this a new air sleeve boom sprayer was designed, developed and its performance was evaluated in the laboratory and field trials. The working principle of the sprayer was totally based on the replacement of air within the canopy with spray laden air. A laboratory set up was developed and tested on actual plant canopy of cotton crop at four experimental variables viz, air velocity (12, 20 and 26 m/s), air sleeve angle (-150 , 00 , 150 and 300 ), nozzle angle (250 , 350 and 450 ) and height of boom (50 cm and 70 cm). In the study, special emphasis was given to determine the effective droplet density and droplet size for the control of pests. The deposition of droplet was made at top, middle and bottom position of the plant and on upper and lower leaf surfaces. The results indicated that the recommended levels of droplet density and size were obtained at an air velocity of 26 m/s, air sleeve angle 300 , nozzle angle 350 and height of boom 70 cm during lab experiment. The deposition indices during field trials were also calculated at these selected levels of variables. The value of regression coefficient was calculated in laboratory experiments to determine the effect of air velocity, air sleeve angle, nozzle angle and height of boom and to confirm field experiments.

Coimbatore district in Tamil Nadu, renowned for its lush greenery, has
seen rapid population growth and unchecked development in recent times,
leading to a decline in urban green spaces and increased environmental
concerns. To address this, rooftop gardening has been proposed as a
sustainable and cost-effective solution. This study aimed to evaluate the
perception and attitude towards rooftop gardens among urban residents of
Coimbatore district. A descriptive quantitative study was conducted, in which
sampling of 80 respondents was done through systematic sampling method
with a pre tested well - structured interview schedule. Data analysis involved
SPSS and MS Excel, focusing on descriptive statistics. Results showed that
the majority of respondents (85%) had favourable attitudes towards rooftop
gardening, while a very few had an unfavourable attitude (3.3%). In terms of
perceptions, three-quarte rs (75%) had positive views, and in terms of overall
negative perception (54%) showing negative views. However, half of the
respondents (54%) on overall perceptions still held negative views towards
rooftop gardening. Thus, effective policy interventions and collaborative
efforts involving government and municipal authorities are necessary to
promote the acceptance of rooftop gardens among urban residents.

In order to evaluate physiological traits related to biochemical basis of drought tolerance under moisture stress, a field experiment with ten sorghum genotypes was carried out in split plot design with three replications. Seeds were grown separately under three moisture regimes viz; moisture stress condition with irrigation applied at the time of sowing, terminal stress condition with irrigation applied at the time of sowing and panicle initiation stage and non stress condition with irrigation applied at various critical growth stages. The accumulation of proline and glycine betaine was higher under moisture stress than terminal stress and non-stress condition. Accumulation of proline and glycine betaine content was recorded at the time of 50% flowering and at dough stage to estimate the efficiency of drought tolerance. Among the genotypes under study, RSV 1237 accumulated more leaf proline, whereas, RSV 1572 accumulated more glycine betaine at 50% flowering stage and dough stage under moisture stress. Genotypes differed significantly with respect to leaf, stem, panicle and total dry matter per plant. RSV 1237 and RSV 1572 had better partitioning of dry matter into reproductive parts under moisture and terminal stress conditions. It was concluded that these genotypes could be useful in sorghum breeding for drought tolerance.

An experiment was conducted at Agricultural College and Research Institute, Madurai, during 2011-12 to study the production potentials of tomato hybrid COTH 2 under naturally ventilated polyhouse and open condition. Observations on biometric and quality traits were made at every month of planting so as to study the environmental influence on growth, yield and quality of tomato. Plants grown under naturally ventilated polyhouse exhibited superior performance in terms of robust growth, early flowering, extended duration, the highest yield and good quality fruits. The tallest plants (187.3 cm) were obtained in October planting in polyhouse as compared to open field condition. Plants grown in polyhouse also exhibited early flowering in 26 days of transplanting. All the other vegetative and reproductive traits viz., number of branches (4.80), number of flowers per plant (39.65), number of fruits per plant (52.4), fruit length (6.20cm), fruit girth (13.83 cm), fruit weight (71.3 g), dry matter production (121.49 g) and fruit yield per plant (3.70 kg/plant) was found to be the highest during the month of October closely followed by September planting in naturally ventilated polyhouse. Whereas in open condition, planting during the months of June, July enhanced biometric characters. The yield was almost tripled under polyhouse condition, as compared to open field planting. The biochemical constituents viz., Ascorbic acid and TSS were found to be influenced by the growing environment.
