Les métiers des filières d’élevage souffrent d’un manque d’attractivité. Un groupe de travail du GIS Avenir Élevages s’est donné pour objectif d’analyser ce manque d’attractivité afin d’y remédier. Ce groupe a conduit de nombreuses enquêtes qualitatives et quantitatives entre 2019 et 2021 pour répondre à plusieurs questions : Quels sont, aujourd’hui, les métiers de l’élevage en tension et quels sont leurs facteurs d’attractivité ? Quelles sont les attentes des personnes susceptibles de les exercer ? Comment pourront évoluer les métiers des filières de l’élevage et leur attractivité d’ici 10 à 15 ans ? Dans un premier temps, un état des lieux des métiers en tension et de leurs facteurs d’attractivité a été réalisé à partir de la bibliographie et d’entretiens auprès d’acteurs des filières d’élevage. Des freins à l’attractivité, communs aux différents métiers, ont été mis en évidence : leur image est mitigée, la rémunération est faible, les conditions de travail sont perçues comme difficiles, et leur accès peut être compliqué. Toutefois, certaines caractéristiques de ces métiers attirent les jeunes, comme le contact avec les animaux et la diversité des tâches inhérents au secteur de l’amont, et le sentiment d’être utile à la société. Dans un second temps, un travail prospectif à moyen terme a été réalisé avec un groupe d’experts et de professionnels de l’élevage. Les métiers de l’élevage ont été décrits dans quatre scénarios prospectifs : un scénario « anti-élevage » ; un scénario « alternatif » ; un scénario « libéral » ; et un scénario « diversification et montée en gamme de l’élevage ». Ces travaux invitent à réfléchir à des pistes d’amélioration de l’attractivité des filières d’élevage, comme une meilleure communication sur la diversité des métiers qu’elles proposent et une amélioration des conditions de travail.

This study aims to determine the projections of the number of school-age residents; ages 7-12 years, ages 13-15 years, and ages 16-18 years; in 2018 to 2025 based on the number of school-age population in 2015, 2016, and 2017. The study also projects the number of students in primary education (SD/ MI and SMP/ MTs) and secondary education (SMA/ SMK/ MA) based on the growing trend of the school-age population. Eventually, the study also calculates the projections of teacher and the projections of infrastructure. The study used a quantitative approach with descriptive methods by describing the documentation and interviews. The study was in Sukamakmur Sub-District, Bogor Regency. The result shows that the growth of the elementary age population,7-12 years, has decreased every year. Conversely, secondary school-age population increase every year. Regarding student projections, it is found that there is a difference between the number of students and the number of school-aged residents attending school at the appropriate level. The result also shows that there are some people who are not aged 7-12 attending primary education. The same thing happened to the high school level. This indicates that there are many junior high school graduates who do not continue their education to the senior high school level. Regarding teacher projections of elementary school teachers, the ideal ratio of teachers: students are 1:20, but the reality is 1:29. This shows that it is necessary to add the number of teachers to elementary schools in order to achieve the ideal ratio for the sake of effectiveness of learning. In contrast, junior and senior high school that already meets the ideal ratio, where for junior and senior high school are 1:15 and 1:12 respectively. This shows that there are excess numbers of teachers at the junior and senior high school level. Therefore, it is necessary to increase school enrollment rates

Authors: Hediati Febri Noor , Azim Saiful 
Published: March 2024

This legal writing examines the utilization of new and renewable energy as an environmentally friendly approach to electricity consumption. New and renewable energy (EBT) encompasses various primary sources such as solar (PLTS), geothermal (PLTP), water (PLTA), wind (PLTB), etc. To meet the high demand for electricity, harnessing energy from sunlight is explored as an alternative power generator. Utilizing buildings’ roofs for solar cell installation is a common practice. However, challenges arise including the initially high investment for purchasing solar cell components, batteries for energy storage, inverters, and installation costs. Despite these challenges, the monthly operational costs are minimal. The government, through Regulation of the Minister of Energy and Mineral Resources of the Republic of Indonesia Number 26 of 2021 concerning rooftop solar power systems, supports the legal framework of this which is linked to the electricity grid held by the license holders for electricity supply for public purposes. Furthermore, rooftop solar power systems can be on-grid with the national electricity network (jaringan PLN) to meet energy needs when the installed capacity is below the electricity demand of the consumers. This writing employs a research method with a normative juridical approach by examining literature through a doctrinal perspective. The research results focus on the legality, requirements, and processes involved in the construction of rooftop solar power plants, detailing considerations across various factors before deciding to establish them, including the procedures, regulations, and agreements when integrating rooftop solar power systems into the national electricity network managed by the state electricity company.
Highlights:

High Initial Investment: Discusses the challenges related to the upfront costs of purchasing solar components, batteries, inverters, and installation despite minimal operational costs.

Government Support: Emphasizes the role of government regulations, such as Regulation Number 26 of 2021, in supporting and providing a legal framework for rooftop solar power systems connected to the national electricity grid.

Integration with National Grid: Highlights the on-grid capability of rooftop solar power systems, enabling them to supplement energy needs and aligning with the capacity of the national electricity network managed by the state electricity company (PLN).

Abstract

Heterocycle skeletal editing has recently experienced a renaissance in chemical synthesis by offering a simple retrosynthetic disconnection between complex structural scaffolds and simple starting materials. However, asymmetric dearomatization of heteroarenes through single atom “cut and paste” remains unknown to date. Herein, we report the first enantiodivergent dearomative skeletal editing of indoles via single-carbon-atom insertion using trifluoromethyl N-triftosylhydrazones as carbene precursors. This strategy provides a straightforward methodology to access both enantiomers of 3,4-dihydroquinolines containing a trifluoromethylated quaternary stereocenter by switching the chirality of catalyst. The synthetic utility and enantiodivergent nature of this methodology were demonstrated by scope evaluation, product derivatization, and the short synthesis of drug analogues. Mechanistic studies disclose that selectivity and asymmetric induction are under catalyst control during the initial cyclopropanation step.

Abstract

Futuristic technologies like morphing aircrafts and superstrong artificial muscles are hinged on metal alloys being as strong as an ultrahigh-strength steel (with a high yield strength σy >1 GPa) yet as flexible as a polymer (with an ultralow elastic modulus E ~10 GPa)1-3. However, achieving such “strong yet flexible” alloys has proven challenging4-9. The difficulty lies in an inevitable trade-off between strength and flexibility5,8,10, which precludes a high-strength alloy from being of polymer-like ultralow modulus. Here we report a Ti-50.8 at.% Ni strain glass alloy showing an unprecedented combination of an ultrahigh yield strength σy ~1.8 GPa with a polymer-like ultralow elastic modulus E ~10.5 GPa, together with a superlarge rubber-like J-shaped elastic strain of ~8%. As a result, it possesses the highest flexibility figure of merit σy/E ~0.17 which far exceeds that of existing structural materials. This alloy was fabricated by a simple 3-step thermomechanical treatment, which leads to not only ultrahigh strength but also ultralow modulus through forming a unique “dual-seed strain glass” (DS-STG) microstructure, being a strain glass matrix embedded with a small amount of R and B19' martensites. In-situ x-ray diffractometry reveals that the DS-STG enables a nucleation-free reversible transition between strain glass and R and B19’ martensites during stress loading/unloading, thereby leading to ultralow modulus and large recoverable strain with narrow hysteresis. Our finding may open a new horizon for designing and mass-producing strong and flexible alloys and such alloys may lead to important applications.

Abstract

Purpose To evaluate the efficacy of ultrasound guided ruthenium (Ru 106) plaque brachytherapy for treatment of exudative retinal detachment in diffuse choroidal haemangioma (DCH).Methods Retrospective analysis of four paediatric patients treated with ultrasound guided Ru 106 plaque brachytherapy for DCH with total exudative retinal detachment directed to the thickest part of the DCH. A dose of 40 Gy to the tumour apex was delivered in all patients. The outcomes of treatment were regression of DCH, resolution of retinal detachment, development of neo-vascular glaucoma or any other radiation associated complications which were assessed clinically and with B scan ultrasonography.Results The mean (median, range) pre-operative tumour thickness was 5.0 (5.12, 4.2–5.5) mm. The visual acuity ranged from 0.8–2.8 LogMAR and 3 of 4 eyes had only light perception at presentation. One eye had been treated with goniotomy for pre-existing secondary glaucoma and was on topical antihypertensive medications. At a mean follow up of 14.6 months (10.5 months, 6–30 months), all patients showed regression of the tumour. The mean tumour thickness reduced to 2.05mm (2.44mm, 1.1-2.6mm) post-operatively. Also, all patients (4/4) had complete resolution of the retinal detachment. The visual acuity remained stable in all the patients with none of the patients developing neovascular glaucoma or any other radiation related complications.Conclusion Ultrasound guided Ru 106 plaque brachytherapy is an effective treatment strategy as a primary treatment in the absence of external beam radiotherapy, to achieve tumour regression and resolution of retinal detachment in DCH.

Abstract
In this study, low density silica nanoparticles (LDS) were produced utilizing the simplified stobber method with amino propyl tri ethoxy siliane (APTES) as an amine. The produced particles were calcined at 400°C to create low density particles. The produced particles were characterized using SEM, FTIR, DLS, and zeta potential analyses. The results confirmed that the particle size, charge, and density varied depending on the APTES concentration. The findings revealed that at lower APTES concentrations, small particles (70–75 nm) were formed, however at higher concentrations, larger particles (420–430 nm) were produced. The particle density varied according to APTES content; following calcination, the control sample had a density of 1.86 g/cm3, while the density of the APTES-added samples differed. UV absorption spectra showed substantial variations between 440 and 480 nm in APTES-added samples. Zeta potential tests showed that the greater concentration of APTES added sample was −10 mV, while the lower concentration was−26 mV. The catalytic activity was determined using crystal violet dye, and the kinetics were described. HRP-coated LDS was employed as a nanosensor to detect H2O2. Results showed linearity of 5×10−10  ~ 1×10−5 (M) (R2 = 0.995), and a detection limit of 5 nm mol. The milk was spiked with H2O2 in various concentrations and utilized as detections for the real sample analysis; the findings showed that the recovery rate was increased.
