Published: January 2024

Nepal’s agriculture extension service delivery has been restructured in accordance with federal constitutional provisions. The constitutional provisions promise good governance and service delivery to the people, ensuring equal and easy access to services and to make public administration clean, competent, impartial, transparent, responsible, and participative. In this context, this research was design to study cereal growing farmers’ perception on effectiveness of local public agriculture extension service in three municipalities of Rupandehi district selecting 120 respondents. Non-experimental survey research design was employed using Likert scale to measure perception of farmers. The overall effectiveness index of selected extension service was assessed using five parameters. Public extension services in the study site were viewed as being effective with relative index value of 0.71. Participation of farmer in decision making, involving them in planning was found to be satisfactory. Although, there appeared the issue of affordability of service with index value (0.51), timeliness (0.53), and long documentation procedure (0.54) with the obtained extension services. However, frequency of extension officials on visiting farmers field, farmers education and their household size have positive and significant impact on cereal production at study site. Moreover, there is need of restructuring service delivery in local level considering these underlying factors.

Published: January 2024

Due to the rapid augmentation of COVID-19 cases, the operations of many businesses and institutions, as well as the occupations of people, have been affected. Employers and employees cannot work in a traditional office because of this pandemic. As a result, the majority of nations have adopted work-from-home (WFH) arrangements as a new work arrangement to keep staff employed and to avoid people becoming infected with a virus. The main purpose of this study is to assess the impacts of implementing WFH on employee productivity. The experiences of employees working from home were also determined. The study was conducted at the Laguna Provincial Capitol. The survey included 71 employees, ages 21 to 60, who currently work from home or have previously worked from home. The hypothesis was also tested: whether working from home or in the office affects productivity significantly. The results led to the rejection of the null hypothesis and demonstrated that WFH arrangements and working at home differ significantly. These results show that employees are more likely to work from home than in an office. As a result, even if no pandemic occurs, the concept of working from home should be incorporated into work arrangements.

Authors: Adusei Frank Yeboah , Adusei Mavis Afriyie
Published: January 2024

The study aims to identify commonalities and differences in these perceptions and to test the hypothesis of a significant relationship between poverty status and food security at the household level in the district. The study utilized primary data collected through a questionnaire survey of farm households and secondary data from relevant literature sources. The results of the study indicate that poverty and food insecurity in the Bosome Freho district are influenced by a complex interplay of factors. Three distinct causes of poverty were identified: structural, individualistic, and fatalistic. Structural causes, deeply rooted in economic, social, and political structures, were associated with the most severe form of food insecurity. Individualistic causes, related to individual behavior and circumstances, were classified as mildly food insecure and could be addressed through education and training. Fatalistic causes, such as natural disasters and political instability, were categorized as moderately food insecure and required emergency assistance. The findings underscore the importance of addressing the root causes of poverty and food insecurity through a multi-faceted approach. This includes systemic changes to address structural factors, individual and community-level interventions to tackle individualistic causes, and emergency assistance to deal with temporary crises caused by fatalistic factors. The study highlights the need for policy changes, social programs, and education to address structural inequalities and promote long-term food security in the district.

Authors: Puspita Kharisma Galuh , Abadi Abadi
Published: January 2024

Dengue hemorrhagic fever is an infectious disease caused by the dengue virus and transmitted by mosquito bites that has spread rapidly to all regions of the world in recent years. One of the efforts to eradicate mosquitoes that cause dengue fever is by fogging or fumigation. In addition, a treatment is also needed for dengue sufferers because there is no special drug or reliable vaccine and treatment can only be done symptomatically. In this study, a mathematical model of dengue spread will be constructed with the influence of treatment and fogging by dividing into two populations, namely humans and mosquitoes in the human population consisting of four groups, namely susceptible humans ( Sh) / Susceptible, infected humans ( Ih) / Infected, treated humans (Th ) / Treated, cured humans (Rh ) / Recovered. The mosquito population consists of two groups, namely susceptible mosquitoes (Sh ) / Susceptible and infected mosquitoes (Ih )/ Infected. The model in this study determined disease-free and endemic equilibrium points. Next, find the basic reproduction number or  and analyze the stability of the disease-free equilibrium point obtained if R0< 1 then the disease-free equilibrium point is asymptotic stable if all eigenvalues are negative, then the endemic equilibrium point is asymptotic stable and the last step is numerical simulation with Matlab 2017b software with parameters according to relevant references or research.

Authors: Yulistina Fika , Juniati Dwi
Published: January 2024

Monyet merupakan salah satu jenis mamalia primata yang termasuk dalam sub-ordo Anthropoide. Beberapa spesies monyet telah mengalami penurunan jumlah secara signifikan pada beberapa dekade terakhir, oleh karena itu diperlukan suatu metode untuk mendeteksi keberadaan populasi monyet di suatu wilayah sebagai upaya untuk meningkatkan konservasi monyet agar terhindar dari ancaman kepunahan. Diketahui bahwa sebagian besar habitat monyet adalah hutan yang merupakan alam bebas dengan memiliki banyak pohon dan berbagai satwa lain di dalamnya, hal ini mengakibatkan keterbatasan untuk mendeteksi populasi monyet di suatu wilayah. Dalam komunikasi vokal, monyet mengeluarkan berbagai jenis suara, dimana suara yang dikeluarkan oleh monyet dari jenis yang berbeda dapat menghasilkan sinyal suara yang berbeda, sehingga memunculkan suatu karakteristik. Dari informasi karakteristik tersebutlah pada penelitian ini akan dilakukan klasifikasi jenis monyet berdasarkan suara dengan menerapkan metode dimensi fraktal Higuchi dan klasifikasi K-Nearest Neighbor (K-NN). Tahapannya yaitu pre-processing data, kemudian ekstraksi ciri dengan dekomposisi suara hingga level 7 menggunakan Discrete Wavelet Transform (DWT) berjenis mother wavelet Daubechies db4. Selanjutnya melakukan perhitungan nilai Higuchi. Dari nilai Higuchi yang telah didapat, dilakukan tahap klasifikasi K-NN. Pada penelitian ini menggunakan rasio pembagian data menjadi data training dan data testing sebesar 0,5 : 0,5, pada Kmax = 50 dan k = 3 didapatkan hasil akurasi tertinggi yaitu sebesar 90,38%. Dari hasil akurasi yang tinggi disimpulkan bahwa metode Higuchi dan K-NN dapat diterapkan pada klasifikasi jenis monyet berdasarkan suara.

The nonparametric regression approach is a statistical method used to determine the relationship between predictor variables and the dependent variable when the assumed pattern is unknown. Truncated spline is an estimator used in nonparametric regression to handle data with varying behaviors. Nonparametric regression modeling with truncated polynomial spline was applied to local Indonesian tourist visitation data obtained from BPS for the years 2017-2019, for each month. The optimal knot points were selected based on the smallest Gross Cross Validation values. Based on the analysis, the optimal model is a second-order spline with the smallest Gross Cross Validation value of 17,95 and the optimal knot points are in the 2nd, 6th, and 7th months. The goodness of the model is evident from an  value of 81,88% and an MSE of 12,46. The best model obtained shows a fairly accurate ability to explain the estimated number of domestic tourists so that it can be a basis for stakeholders to make key decisions in planning and managing the tourism industry as an effort to increase domestic tourism interest.

Elaboration of drones for conveying a radar to reach difficult areas will support the effective use of this technology. However, fluctuations in flight altitude allow dynamic clutter to emerge. The existence of dynamic clutter has a significant influence on the detection results. A method to reduce dynamic clutter in radar altitude is needed, and this paper proposes a dynamic clutter reduction method that consists of utilizing the altitude fluctuation data itself to identify additional Doppler responses due to dynamic clutter and then used to control the post-filtering of the phase detection results. Laboratory simulations and experiments with FMCW radar have been carried out, showing that the proposed method can significantly improve the detection results.Keywords: Radar, Drone, Rubble, Vital Sign, FMCW.

Another method to see the nature of selectivity is to use imagery. A thickness function based on Beer-Lambert's law is used to produce this image. The materials used are meat, skin, and bones from chickens. This research aims to create images based on the thickness function to determine the nature of selectivity between materials. Beer-Lambert's law states that the intensity value will be attenuated depending on the exponential function of the attenuation coefficient and thickness. By linearizing this equation, we get the thickness value of a material. The research results show that an image can be displayed by calculating the thickness function value. In this image, the materials show different contrast ratios. Near-IR sources are used at wavelengths of 780 nm and 980 nm. The results show that the wavelength of 980 nm leads to better selectivity properties.Keywords: selectivity, attenuation coefficient, Beer-Lambert law, contras ratio, Imaging.

The CRISPR /CAS system is a modern genome editing tool derived from a bacterium as it functions as an active immune system to prevent the bacteria from the viruses and plasmids. In the earlier years before the discovery of the CRISPR system, there were many other tools to perform genome editing but due to their low specificity and reliability, they were not considered an efficient tool. The discovery of CRISPR/CAS9 system overcomes these limitations and considered as a highly specific and efficient technique in the field of genome editing or DNA alteration. The purpose of studying the CRISPR/CAS system is to develop a powerful gene-editing tool that can make every possible gene editing and also to prevent the genomic defect in a certain group of organisms. The CRISPR/CAS9 system uses an RNA molecule which is a main functional part of the CRISPR through which a bacterial cell can recognize and cleave/destroy the foreign viral elements that enter the bacterial cell using a certain group of restriction nuclease enzymes isolated from different bacteria. Several repairing mechanisms in the cell have been used to ligate the degraded viral sequences as these repair mechanisms are error-prone and generate frame shift mutations in the sequence. As a result, the foreign viral components and their expressions were reduced or deleted. The purpose of this review is to understand the mechanism of bacterial CRISPR/CAS9 system and also to know the use of this technique to prevent single genomic defects. In this review discuss the role of the CRISPR/CAS9 system as an active immune system of bacterial cells, classifications, and the CRISPR/CAS9 system (type II) use in the genome-editing mechanism.

Published: January 2024

The purpose of this study is to examine the musical experience of young children from the perspective of Deleuze's philosophy and to understand the events and meanings generated from the encounters between young children and musical instruments. To this end, 10 children aged 3-5 in a mixed class of a daycare center were observed participating in special music activities for about 4 months, and as a kind of post-qualitative research method, Deleuze's philosophical concepts were used for analyzing the data generated. As a result of the study, young children created new meanings through various sensory encounters in music activities using musical instruments, and invented their own musical styles through creative experiments and expressions. In addition, the children's musical instrument activities were interpreted as the meaning of new creation through agential practices of musical ‘becoming.’ Based on these results, it was suggested that looking at young children's musical activities with an open eye by focusing on their encounters with materials and relationships, and moving from the standardized teaching approaches to new meanings created by musical instruments through philosophical thinking.

AbstractSemarang is one of the cities that often occurs flood disaster due to very high rainy weather. This resulted in the Ahmad Yani airport runway being inundated with water as high as approximately 50 cm around the airside which could disrupt flight operations. Therefore it is necessary to have a flood prevention activity to minimize the situation. The purpose of this study is to determine the factors resulting from flooding on the airside of Ahmad Yani airport and to determine the design of short-term and long-term drainage systems. In calculating the planned flood discharge (R24) using data such as rainfall, channel measurement data, and the condition of the channel. Based on this data, the researcher will calculate the planned rainfall for the Q2, Q5, Q10, Q25, Q50, and Q100 years. To calculate the data, we use the Normal Distribution, Log Normal Distribution, Pearson III Log Distribution, and Gumbel Distribution. Then from these calculations the Gumbel distribution method was chosen because it is closer. Based on data processing using the Rational method, the peak flood discharge value (QP) is obtained when Q2 all channels are able to accommodate the planned flood discharge, Q5 there is 1 channel unable to accommodate, namely in DU1-P2, Q10 there is 1 channel unable to accommodate, namely in DU1- P2, Q25 there are 1 channel that is not able to accommodate, namely in DU1-P2, Q50 there are 2 channels that are unable to accommodate, namely in DU1-P2 and S1B-P7, Q100 there are 2 channels that cannot accommodate, namely in DU1-P2 and S1B-P7. For the short-term drainage system design for flood management, it includes: repairing damaged channels, improving the foundation of the west side BRC fence, repairing pump station access roads, improving airside embankments, and pumping operations. In the design of the long-term flood control drainage system, the dimensions of the drainage channel on the airside side are added because there are 2 (two) channels that are not able to accommodate the planned discharge at the 50-year return period (Q50) with the addition of dimensions in the channel DU1-P2 b = 3, 5 h = 0.5 and S1B-P7 b = 2.7 h = 0.9.Keywords: Flood, Ej Gumbel, prevention.

The Ga-doped Li7La3Zr2O12 (LLZO) Solid State Electrolyte (SSE) has been synthesized via solid-state reaction. The structural study of the SSE was conducted with the help of X-ray diffraction and the Rietveld method. The SSE crystallizes in the Li6.25Ga0.15La2.90Zr2O12 phase with cubic space group number 220 and unit cell parameter 13.02081 Å, and La2Zr2O7 impurity phase with cubic space group number 227 and unit cell parameter 10.79475 Å. Obtained lattice planes in the refinement were confirmed with the help of TEM. The core of the Li-ion migration channel has been defined as the loop formed by the Li32, Li1, Li2, and Li22 sites with minimal Li...Li distance and occupational disorganization of the Ga-doped LLZO SSE. The electron density plots of the Li6.25Ga0.15La2.90Zr2O12 phase have shown maximum distribution of electrons inside the unit cell for lanthanum atoms. XPS confirmed the presence of all the precursors i.e., Li, La, Zr, Ga, and O in the synthesized compound. The elemental composition was confirmed with the help of EDX. In the direct current charge-discharge behavior of the Li symmetric cell no voltage breakdown was observed even at 6 mAcm‑2 current density and after 400 charge/discharge cycles for over 200 hours.
