Published: July 2022

Padi lokal memiliki keunggulan pada rasa dan aroma, namun memiliki produksi yang rendah dan umur panen yang lama sehingga kurang unggul. Upaya untuk memperbaiki genetik padi lokal adalah melalui persilangan buatan. Tujuan penelitian ini adalah untuk mempelajari tingkat keberhasilan persilangan, heterosis, karakter kualitatif dan kuantitatif F1, dan kekerabatan F1 dengan tetuanya. Penelitian dilaksanakan di Kecamatan Tallunglipu, Kabupaten Toraja Utara dari Januari 2019 hingga Juli 2020. Metode persilangan yang digunakan yaitu single cross dan resiprocal cross menggunakan padi lokal aromatik Pare Bau dengan Inpari 4 sehingga diperoleh dua kombinasi persilangan. Hasil penelitian menunjukkan persentase keberhasilan persilangan single cross sebesar 14,4% dan persilangan resiprok sebesar 25,5%. Karakter hasil F1 persilangan resiprok, jumlah gabah bernas per malai (164,2 gabah) dan bobot gabah bernas per rumpun (96,4 g), lebih tinggi dibandingkan F1 single cross. Karakter keharuman pada waktu berbunga terbaik dihasilkan oleh tanaman F1 single cross B1 senilai 92,2% dan B2 senilai 95%. Nilai heterosis dan heterobeltiosis tertinggi adalah F1 resiprok pada semua karakter yang diamati. Generasi F1 hasil single cross (B1 dan B2) memiliki kekerabatan dekat dengan Pare Bau, sedangkan generasi F1 hasil persilangan resiprok (RB1, RB2, RB3, RB4, dan RB5) membentuk kelompok genetik tersendiri tetapi memiliki kekerabatan dekat dengan Inpari 4. ABSTRACTThe rice landrace has a great taste and aroma, but has low yield and late maturity. The artificial crossing is one of ways to improve the genetics performance of the rice landrace. This study purposed to observe the success rate of crosses, heterosis, heterobeltiosis, qualitative and quantitative characters of F1, and genetic relationship of the F1with its parents. This research was conducted in Tallunglipu District, North Toraja Regency from January 2019 to July 2020. The crosses method used were single cross and reciprocal cross using local aromatic Pare Bau and Inpari 4 varieties in order to obtain two cross combinations. The results showed the success rate of the single cross was 14,4% and the reciprocal cross was 25,5%. The characteristics of the F1 reciprocal crosses, the number of fully developed grain per panicle (164,2 grain) and the weight of pithy grain per clump (96,4 g), was higher than the F1 single cross. The best level of aroma character at the time flowering was produced by F1 single cross i.e B1 92,2% and B2 95%. Resiprocal F1 had the highest value of heterosis and heterobeltiosis in all observed characters. Single cross lines (B1 and B2) were closely related to Pare Bau, while reciprocal cross lines (RB1, RB2, RB3, RB4, and RB5) formed separate genetic groups. However, reciprocal cross lines were closely related to Inpari 4.

Jagung merupakan komoditas prioritas nasional strategis dengan kebutuhan yang sangat tinggi untuk industri pangan, pakan dan benih. Produksi jagung dapat ditingkatkan dengan penggunaan jagung jenis hibrida dan perluasan areal tanam dengan memanfaatkan lahan sawah tadah hujan. Penerapan sistem tanpa olah tanah (TOT) pada jagung di lahan tadah hujan sangat efektif diterapkan untuk mempercepat waktu tanam, meminimalkan biaya produksi dan meningkatkan indeks pertanaman jagung, dan untuk meningkatkan produksi jagung. Tujuan dari penelitian ini adalah untuk melihat pertumbuhan agronomi dan menyeleksi jagung hibrida potensial untuk dikembangkan di lahan sawah tadah hujan dengan sistem tanam TOT. Penelitian dilaksanakan pada lahan sawah tadah hujan tanpa olah tanah menggunakan 5 hibrida jagung dan 3 varietas pembanding dengan Rancangan Acak Kelompok, 4 ulangan. Secara umum penampilan agronomi jagung hibrida uji lebih baik dari varietas pembanding. Terdapat dua hibrida yang memperlihatkan hasil pipilan kering lebih tinggi dari varietas pembanding yaitu HIB1 (11,77 t ha-1) dan HIB3 (11.61 t ha-1). Kedua hibrida ini juga memiliki karakter agronomi yang lebih tinggi dari varietas pembanding pada karakter diameter tongkol, jumlah baris biji per tongkol dan jumlah biji per baris. Jagung hibrida HIB1 dan HIB3 dapat menjadi pilihan dalam pengembangan jagung di lahan sawah tadah hujan dengan sistem TOT. ABSTRACTCorn is a strategic national priority commodity with a very high demand for the food, feed, and seed industry. Corn production can be increased by using hybrid maize and expanding the planted area by utilizing rainfed rice fields. The application of zero tillage system (TOT) on maize in rainfed land is very effective to be applied to speed up planting time, minimize production costs and increase maize cropping index to increase maize production. The purpose of this study was to observe the agronomic growth and to select potential hybrid maize to be developed in rainfed fields with zero tillage cropping system. The research was carried out on uncultivated rainfed fields using 5 maize hybrids and 3 comparison varieties with a randomized block design and, 4 replications. In general, the agronomic performance of the test hybrid corn was better than the comparison variety. There were two hybrids that showed higher dry seed yields than the comparison varieties, namely HIB1 (11.77 t ha-1) and HIB3 (11.61 t ha-1). These two hybrids also had higher agronomic characteristics than the comparison varieties on the characteristics of ear diameter, the number of rows seed per ear, and number of seeds per row. Hybrid corn HIB1 and HIB3 can be an option in the development of maize in rainfed rice fields with the TOT system.

Pertumbuhan tomat pada lingkungan berbeda memberikan perbedaan hasil karena adanya interaksi genetik x lingkungan yang mempengaruhi ekspresi suatu gen pada kondisi lingkungan tertentu. Penelitian ini bertujuan untuk menduga nilai ragam genetik serta nilai heritabilitas arti luas pada genotip tomat tipe determinate di dua lingkungan tanam. Penelitian dilakukan dari Maret hingga Juli 2021 dengan menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) di dua lingkungan tanam (Depok dan Jakarta). Perlakuan terdiri dari 3 genotip tomat generasi F6 dan 2 varietas komersil diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa lingkungan tanam memberikan pengaruh terhadap pertumbuhan dan perkembangan genotip tomat yang digunakan. Nilai ragam genetik pada setiap karakter tergolong dalam kriteria sempit, kecuali pada karakter tebal daging buah dan luas daun. Nilai heritabilitas arti luas terhadap karakter yang diamati menunjukkan kriteria tinggi, kecuali pada karakter diameter buah (kriteria sedang) dan karakter tinggi tanaman (kriteria rendah). Genotip RwTa-4-10U-6U-4U-2U memberikan penampilan terbaik pada kedua lokasi tanam, dengan tinggi tanaman lebih rendah (91,09 cm), diameter batang lebih kekar (9,69 mm), buah lebih panjang (5,64 cm), diameter buah lebih besar (4,25 cm), total padatan terlarut lebih tinggi (5,22ºBrix), bobot per buah lebih besar (48,43 g), serta umur berbunga lebih genjah (25 HST) dibandingkan varietas Tantyna dan varietas Tora.ABSTRACTTomatoes growth in different environments give different results due to genetic x environment interaction that affect the expression of genes in a certain environmental condition. This study aimed to estimate the genetic variance and the broad sense heritability of determinate tomato genotypes in two growing environments. The study was conducted from March to July 2021, using a Randomized Complete Block Design (RCBD) in two planting environments (Depok and Jakarta). The treatments consisted of 3 genotypes of tomato generation F6 and 2 commercial varieties with 3 replications. The results showed that the environment affected the growth and development of the tomato genotypes used. The genetic variance was classified into narrow criteria except for flesh thickness and leaves area. The heritability value showed high value except for fruit diameter (medium) and plant height (low). The genotype RwTa-4-10U-6U-4U-2U gave the best performance at both planting locations, with lower plant height (91.09 cm), more harder stem diameter (9.69 mm), longer fruit (5.64 cm), larger fruit diameter (4.25 cm), higher total dissolved solids (5.22ºBrix), greater weight per fruit (48.43 g), and early flowering (25 DAP) compared to the Tantyna and Tora varieties.

Water contamination with heavy metals is increased due to environmental contaminants. Arsenic, cadmium, mercury, and lead are well-known toxic heavy metals for humans. Lactobacillus acidophilus is an ideal absorbent for the removal of metals from drinking water. In this study, the ability of treated and untreated L. acidophilus ATCC 4356 to remove four heavy metals, simultaneously, from multi-metallic contaminated water in 24 h was investigated. In addition, the stability of the bacteria–metal complexes was evaluated in simulated gastrointestinal tract conditions. According to the results, untreated L. acidophilus could remove 99.01% and 92.35% of mercury and lead in water, respectively (initial concentration of 700 µg.L−1; inoculum size of 2.6×1012 CFU.mL−1; pH 4; 37°C; 24 h), whereas removal of arsenic and cadmium, under the same conditions, was 91.28% and 61.91% by heat and NaOH treated cells, respectively. In the digest condition, the complexes of bacteria-metal were reversible and the bond stability of untreated bacteria–Hg complexes was stronger than other complexes. The results suggest that treated or untreated L. acidophilus ATCC 4356 cells have the potential to adsorb heavy metals in contaminated water.

Authors: Basavarajaiah Sarvesh , Patel Prajwal , Sharma Kanchan 
Published: July 2022

Background: Transverse abdominus plane (TAP) block is a regional anesthetic technique which provides an excellent analgesia without major adverse effects. The primary aim of this study was to evaluate the efficacy of dexmedetomidine in comparison to tramadol when added as adjuvant to levobupivacaine in TAP block on duration of post operative analgesia following laproscopic orchidopexy.
Methods: Sixty American Society of Anaesthesiologists (ASA) grade 1 pediatric patients undergoing laproscopic orchidopexy under general anaesthesia were randomized into two groups (GroupLD and Group LT). Group LD recieved ultrasound guided bilateral TAP block with 0.3 ml/kg 0.25% levobupivacaine with 1µg/ kg of dexmedetomidine on both sides and Group LT recieved TAP block with 0.3 ml/kg 0.25% levobupivacaine with 1mg/ kg of tramadol. During the first 24 h postoperatively, we assessed hemodynamic stability, respiratory depression, and postoperative pain using face, legs, activity, cry, consolability (FLACC) pain scale.
Results: Total duration of analgesia (986.67 ± 47.29 min vs. 690 ± 53.49 min, P value- 0.000), and the total consumption of paracetamol in the first 24 hours postoperatively (324.28 ± 35.5 mg vs. 580.14 ± 38.23, P value – 0.000) were statistically highly significant in group LD in comparison to group LT. The FLACC score were lower in Group LD as compared to group LT and side effects profile were similar in both the groups.
Conclusion: Dexmedetomidine in a dose of 1 μg.kg-1 when added to levobupivacaine in ultrasound guided transverse abdominus plane block significantly prolongs the duration of postoperative analgesia as compared to tramadol with levobupivacaine without major side effects.

Authors: Sadrossadat Seyed Sadegh 
Published: July 2022

Background: Non-invasive mechanical ventilation is one of the most used organ support measures in critical care medicine. Hemet interface has been implemented in everyday practice at ICUs later than classic means of delivery for NIV including face mask. We used helmet interface for first time at ICU and recorded CPAP setting and outcome.
Methods: Helmet was used for 9 patients and any complication or side effects were recorded. Also nurses first experience of using the helmet has recorded in a survey.
Results: No skin lesion, vomiting, and air leaking were recorded. Also none of the patients complained about claustrophobia, dyspnea, pain, or feeling hot while the helmet was in use. In addition, nursing was easier while using a helmet than it was with face mask.
Conclusion: The overall first time use of helmet interface in our department gave us a positive feedback, but more data need to be collected for more effective way of applying NIV and specifically helmet interface.

Published: July 2022

Background: Anaesthesiologists most commonly perform the procedure of internal jugular vein cannulation(IJV) in emergency and also in elective cases. With the use of ultrasound guidance placement of guide wire and catheter into the internal jugular vein has been made easy, safe and with less complications.
Aims: The aim of the study was to compare IJ vein cannulation under ultrasound guidance with respect to Short and Long axis (SA and LA) view approaches.
Methods: Patients who may require central venous cannulation for undergoing surgery and will be in intensive care unit were randomized using computer generated randomization for ultrasound guided cannulation into one of short axis and long axis (SA and LA) approaches group. Success rate of first pass, number of needle attempts made, guide wire insertion time, catheter placement time and complications were noted for each procedure.
Results: Successful cannulation of IJV was achieved in all the patients. Significant results were not noted among the two groups with respect to demographic profile of the patient, catheter placement time, rate of carotid artery puncture. Whereas a significant result was noted in terms of success rate of first pass (97% in SA v/s 53% in LA, P-0.0001), number of needle attempts (mean of 1.05±0.18 in SA v/s 1.55±0.68 in LA, P-0.0001), guide wire insertion time (mean of 43.20±5.64 in SA v/s 74.83±39.36 in LA).
Conclusion: We conclude from the above study that short axis view approach is better with respect to success rate of first pass, number of needle attempts and guide wire insertion time than long axis view approach for internal jugular vein cannulation under ultrasound guidance.
Off-line English character recognition system
Authors: Prasad Binod Kumar , Dubey Om Prakash 
Published: July 2022

Purpose of the study: This paper aims to recognition of handwritten English characters in offline mode. It develops an efficient character recognition model avoiding large variations in handwriting by using better feature extraction techniques. Methodology: The samples of characters are preprocessed by applying a sequence of operations in succession like Thickening, Thresholding, Filtering, and Thinning. Efficient features like Gradient features and Zonal features have been extracted. Gradient features are helpful to find out stroke information in the character whereas Zonal features detail out local information in a more précised way. Hidden Markov Model is the classifier. Main Findings: Classification has been started with only a 5-state HMM model but it is observed that as the number of states of HMM model is increased, the corresponding recognition rate is also improved. Finally, with the 36 states HMM model we have got the expected result. This produces an overall average recognition rate of 92.6%. For the letters ‘A’ and ‘W’, the recognition rate is found to be very low, because of a lot of variations in writing style of these letters. Applications of this study: HMM is a flexible tool which is capable of absorbing variations in character images. The future works will be concentrated on improvement of recognition rate of such letters by finding some demarcating features and post processing. The proposed method can be well used in Natural Language Processing, Signature verification, Face recognition like other Pattern Recognition applications. Novelty/Originality of this study: Preprocessing uses Median filter which removes all stray marks in samples and hence avoids any possibility of false pixels. The combination of Gradient features and Zonal features leads to a recognition accuracy of 92.6% which may be used by researchers in any other domains for the purpose of classification. The application of HMM will motivate the readers to use it for better results of classification.

Authors: Olusanya Oyewole , Jegede Ayodele 
Published: July 2022

Adolescents' sexual and reproductive health remain global public health concerns particularly in Sub-Saharan. Undoubtedly, parent-child communication remains a vital means by which parents transmit cultural values and monitor the sexual health of their children. The nature and the quality of sexual conversations that subsist in the family are critical factors in the prevention of sexual risk-taking behaviour among adolescents. Therefore, this paper investigated the existing practices of parent-child communication on sex-related matters among households in Ondo State among the triads of parents and their adolescent children and the implications for adolescents’ sexual health in Ondo State, Nigeria. The study elicited data from 483 respondents comprising fathers, mothers and their adolescents; through a multi-stage sampling technique. First, the study found that for most of the respondents (fathers 56.5%, mothers 54.7% and adolescents 60.2%) sexual conversations are occasional; second, mothers often initiate sex-related discussion with children more than fathers; third, sexual conversations are generally not open and receptive; fourth, content of parent-child sexual communication chiefly centre on admonitions against premarital sex; fifth, mothers discuss more sexual topics with the adolescent children than fathers. Sixth, discussion about contraceptive with adolescents is a topic which majority of households in the state avoid. Lastly, many parents still have inhibitions discussing sex-related issues with adolescents. There's need for interventions that target parents enlightenment and education and addressing cultural norms that impede parent-child sexual conversations; in order to reposition families for parent-child communication that is open, receptive, sequential and time sensitive; conversations about sexual development and decision-making that enhance adolescent sexual and reproductive health.

Published: July 2022

This paper focuses on measuring the impact of interaction between virtual reality glasses tracking types (Positional - Rotational) and cognitive styles (Impulsivity - Reflectivity) to develop English vocabulary skills among primary-stage pupils with learning difficulties. Five instruments were utilized in the research process and the results reported the test. English vocabulary checklists were employed to identify the vocabulary that will be used in the course of the research. The test are as follows: an English test to identify the learning difficulties of students in the English Language, the test of mental ability to identify the IQ mean scores of students, a standard test of Kagan to measure the cognitive style (Impulsivity - Reflectivity), and pre and post-English vocabulary achievement test. However, immersion scale and the suggested English vocabulary skills program depend on positional - rotational tracking type. The participants were students in grade five and their number is 89 from the primary stage at Tarek Ibn Zaid school, Minia, Egypt. Using four groups of quasi-experimental design, the research followed applying tests of mental ability, English test to identify difficulties, and Cognitive style test of Kagan. It also followed a pre and post-testing procedure before and after applying for the virtual reality program and applying the immersion scale at the end of the program. The quantitative results of the study indicated that there was no interaction between virtual reality glasses tracking type (Positional - Rotational) because of the lack of direct relationship between cognitive style and virtual reality glasses tracking type, especially in immersion with learning and acquiring English vocabulary skills, and that there is no preferred pattern for virtual reality glasses tracking type with one of the cognitive methods that was dealt with in the research. This is most especially in learning and acquiring English vocabulary skills.
