Prevalência de lesões de cárie em escolares de 5 a 6 anos em um distrito sanitário de Curitiba (PR, Brasil)
Authors: Felipe Corazza Goularte  , Cristiano Santana Bentes Junior  , Ana Cristina Allegretti  , Ana Paula Ribeiro Braosi
Published: December 2024

A cárie na primeira infância constitui aquela que envolve a dentição decídua, sendo considerada uma questão de saúde pública e que impacta aspectos tanto de saúde bucal como de ordem psicossocial. Objetivo: Realizar levantamento da prevalência de lesões de cárie em crianças de 5 a 6 anos em escolas de um distrito sanitário do município de Curitiba (PR). Material e métodos: Trata-se de um estudo observacional transversal, descritivo, de caráter quantitativo. A amostra para o levantamento epidemiológico se deu com crianças de 5 a 6 anos, matriculadas e frequentando escolas ou creches municipais presentes no território de uma determinada administração regional da cidade de Curitiba (Paraná). Um examinador e um anotador realizaram exames de saúde bucal simples, no ambiente escolar, fazendo registro dos dados por meio do índice ceo-d e PUFA. Resultados: Avaliaram-se 114 crianças, com a média de ceo-d de 1,5. A proporção de indivíduos ceo-d=0 foi de 60,5%. Dentre os componentes do ceo-d, o mais prevalente foi o elemento cariado, obtendo o índice de 0,96 e representando 64%. O componente extraído apareceu apenas uma vez, logo sendo o componente com menor prevalência. Conclusão: Ao traçar comparações com resultados do levantamento nacional de saúde bucal mais recente (2012), percebe-se a amostra interna com uma prevalência substancialmente menor de lesões cariosas. Tal resultado pode ter sua justificativa em virtude de fatores como diferenças na idade da amostra entre estudos, presença e frequência em instituições de ensino e proximidade com Unidades de Saúde da Família.

Published: December 2024

Odontogenic lesions content can be differed using magnetic resonance imaging (MRI) signal intensity (SI). Objective: This systematic literature review addresses the use of MRI SI for the characterization and differentiation of maxillomandibular odontogenic lesions. Material and methods: Databases were searched for original research studies up to August 2023. The following keywords were used: “magnetic resonance imaging” combined with “maxillofacial pathology,” “oral pathology,” “odontogenic tumors,” “dental tissue neoplasms,” and “odontogenic cysts,” as well as the histologic denomination of benign odontogenic lesions according to the World Health Organization classification. No language restrictions were applied. Results: Sixteen investigations were identified regarding distinct odontogenic lesions such as ameloblastoma, odontogenic keratocysts (OKCs), and dentigerous cysts. Researchers used various terminologies to describe SI, which influenced the findings of the review. Conclusion: MRI SI can be useful in the differentiation of multicystic ameloblastomas from other odontogenic lesions; notably, multicystic ameloblastomas exhibit heterogeneous SI in T2-weighted images, such that cystic components exhibit higher SI compared with solid content. Dentigerous cysts exhibit high SI in T2-weighted images, while OKCs eventually exhibit lower SI. The terminology used for description of SI is heterogeneous and requires standardization to improve communication among researchers and clinicians. PROSPERO registration number CRD42021276536.

Authors: Luiza Barbosa Gama  , Vitor Mattos Rosa  , Jardel Dorigon-Santos
Published: December 2024

External root resorption is characterized by the loss of mineral tissues in the dental root. This condition is difficult to diagnose, and if not identified early, it can lead to tooth extraction. The treatment consists of surgical access, removal of granulation tissues, and sealing the area with a biological material. Objective: This article reports on the treatment of ERR in the middle third of the root, associated with an 8 mm periodontal pocket using Biodentine, with a two-year follow-up. Case report: A 57-year-old woman attended complaining of discomfort in the palate. After a thorough medical history, clinical, radiographic, and tomographic evaluation, the final diagnosis was External Root Resorption. Concerned about preserving the tooth, it was suggested to fill the resorption with Biodentine and regular follow-ups. The patient agreed, and a tissue flap was raised in the palatal region, followed by sealing of the perforation with Biodentine and suturing. After 7 days, the sutures were removed, and during the six-month and two-year follow-ups, the tooth exhibited no mobility, good periodontal health, and maintained its function. Conclusion: The case demonstrated a reduction in the periodontal pocket (from 8 mm to 4 mm), maintenance of the tooth, and the effectiveness of Biodentine in treating ERR, even when exposed to the oral cavity.

Authors: Claudia Tenório  , Tatiana Miranda Deliberador  , Jessica Vavassori de Freitas  , Jeferson Luis de Oliveira Stroparo
Published: December 2024

A apicectomia consiste na ressecção da porção apical da raiz e remoção de tecidos infectados, sendo recomendada a realização de uma regeneração óssea guiada (ROG) para reconstrução do osso alveolar, em que podem ser utilizados biomateriais ósseos e membranas para reconstruir o local da lesão óssea. Objetivo: Relatar um acompanhamento radiográfico de 10 anos de uma cirurgia de apicectomia associada a regeneração óssea realizada em uma área com extensa lesão óssea. Relato de caso: A paciente buscou atendimento odontológico para o dente 22, sendo solicitado exame tomográfico, no qual se notou extensa lesão periapical no dente 22. Então, foi planejada e realizada cirurgia de apicectomia, seguida por descontaminação química e mecânica e ROG com uso de biomaterial xenogênico bovino e membrana reabsorvível. Resultados: Aos 8 meses de pós-operatório o exame radiográfico mostrava o ótimo resultado da regeneração óssea guiada e o sucesso do procedimento. A paciente foi acompanhada, e após 6 anos observaram-se biomaterial ósseo integrado e ausência de lesão. Após 10 anos, na radiografia panorâmica constatou-se ausência de regressão da lesão periapical, com sucesso a longo prazo do procedimento. Conclusão: O procedimento realizado neste relato mostrou um tratamento desafiador, em virtude da extensa perda óssea que poderia levar a prognóstico não satisfatório, porém a boa habilidade clínica, aliada a uma correta desinfecção e protocolo de ROG, possibilitou um resultado satisfatório sem nenhuma presença de recidiva da lesão ao longo do acompanhamento radiográfico de 10 anos.
An Association between Bilirubin and Diabetic Retinopathy in Patients with Type 2 Diabetes Mellitus: An Effect Modification by Nrf2 Polymorphisms
Authors: Fan Qiwei , Feng Shanshan , Chen Jianrong , Zhang Yan , Xu Jixiong , Wang Jiancheng
Published: December 2024

Background:

Diabetic retinopathy (DR) is a persistent microvascular complication associated
with diabetes, and it constitutes a significant cause of visual impairment and blindness.

Aims:

This study aimed to assess the correlation between serum bilirubin levels and the prevalence
of DR in patients diagnosed with type 2 diabetes mellitus (T2DM). Additionally, we sought
to establish whether the polymorphisms of Nuclear Factor E2-Related Factor 2 (Nrf2) might modify
this relationship.

Methods:

A cross-sectional study was undertaken in Jiangxi, China, from May, 2012 to December,
2014. Serum bilirubin levels were assessed in 558 subjects, and the correlation between bilirubin
and DR was analyzed using generalized linear models with a logit link. The study utilized
odds ratios (OR) and 95% confidence intervals (CI) to evaluate the relationship, both with and
without the consideration of clinical risk factors.

Results:

There was a significant inverse association between serum total bilirubin (TBiL) and the
risk of DR (per 1-μmol/L increment; OR, 0.89; 95% CI: 0.84-0.94). Accordingly, when TBiL was
categorized into tertiles, individuals in tertiles 2 and 3 exhibited significantly lower risks of DR
compared to those in tertile 1. The OR for these tertiles was 0.54 (95% CI: 0.34-0.87) and 0.31
(95% CI: 0.19-0.52), respectively. Moreover, a stronger inverse relationship between TBiL and
DR was observed in individuals carrying the CC and AC genotypes compared to those with the
AA genotype. The OR for individuals with the CC/AC genotype was 0.87 (95% CI: 0.82, 0.92),
while that for the AA genotype was 1.17 (95% CI: 0.95, 1.45). This difference was statistically significant
(p for interaction = 0.001).

Conclusion:

There was a significant inverse association between bilirubin and DR in participants
with CC or AC genotype. However, this inverse association was not seen in AA genotype participants.
Review of Patents on Small Grinding Wheel Polishing Technology
Authors: Li Guo , Zhu Kuntan
Published: December 2024

Grinding disc polishing is an important polishing method that can be used to manufacture
various high-precision and high-quality optical components. The smoothing effect of grinding
discs is a simple and effective method widely used to suppress MSF errors. Grinding disc technology
has good polishing effects on flat, spherical, aspherical, and free form surfaces. The polishing
mechanism is to generate chips through the small plastic cutting of abrasive particles, but it only
uses a very small amount of abrasive particles to exert force and uses the flow friction between the
abrasive particles and the grinding disc and the workpiece to flatten the surface roughness of the
workpiece. It can be seen from the relevant literature that the floating tool holder maintains a constant
pressure to solve the problem of uneven pressure distribution between optical components.
The adjustable tool holder can adjust the amount of spring deformation to adapt to local surface
changes of optical parts, ensuring consistent material removal. The force-adaptive tool holder can
be adjusted in real time during the machining process to reduce errors generated during machining.
The jointed tool holder improves the fit between the grinding wheel and optical components,
ensuring a tight fit between the grinding wheel and optical components.
This patent paper aims to introduce grinding wheel polishing technology as an essential method
for manufacturing high-precision, high-quality optical components. It explores the optimization of
abrasive tool design and the improvement of processing efficiency and proposes suggestions and
prospects for future research, applications, and development.
Through querying literature and patent databases, patent documents related to grinding disc polishing
technology were collected and analyzed. The design characteristics of the device structure,
technological innovations, as well as the effectiveness and improvements in practical applications
were focused.
Grinding disc polishing technology effectively removes surface defects and enhances the optical
performance of optical components, particularly in suppressing MSF errors. This technology is
suitable for flat, spherical, non-spherical, and freeform surfaces, with broad potential applications.
Despite the numerous advantages of grinding disc polishing technology, such as simplicity, effectiveness,
and wide applicability, critical issues still need to be addressed, including surface morphology
control, improving polishing efficiency, and enhancing consistency. Future research
should focus on optimizing tool design and developing new polishing materials and processes to
improve the manufacturing quality and efficiency of optical components.

Authors: Faryabi Reza , Bordbar Shima , Bahmaei Jamshid , Yusefi Ali Reza
Published: December 2024

Background and Objective

COVID-19 is an acute respiratory disease that poses a significant threat to public health. Recognizing the impact and costs associated with this disease can assist policymakers in making informed decisions about the allocation of resources. Therefore, this study estimated the economic burden of COVID-19 from a societal perspective, focusing on patients admitted to the referral hospital for this disease in southern Iran in 2022.

Methods

This descriptive and analytical study employed a random sampling method to select patients admitted to hospitals affiliated with Jiroft University of Medical Sciences in southern Kerman, Iran. The sampling period spanned from March 2020 to February 2021. In total, 450 patients were included in this study. A researcher-made checklist was used as the data collection tool. The data were then analyzed using a t-test, ANOVA, and Pearson correlation coefficient. The analysis was performed using SPSS23, with the significance level set at 0.05.

Results

The study estimated the total direct cost, total indirect cost, total cost of the studied patients, and the economic burden of COVID-19 disease as 600,211.89, 193,667.28, 793,879.17, and 4,186,389.48 dollars, respectively. A statistically significant correlation was found between length of stay (r=0.858, p<0.001), type of insurance (F=2.853, P=0.023), and total direct cost.

Conclusion

Based on these results, it is evident that COVID-19 has imposed a substantial economic burden. The study findings emphasize the need for decision-makers to take measures and implement effective interventions to address COVID-19. This can be achieved by controlling risk factors, drawing upon successful experiences from other countries, and following recommendations provided by international organizations. By reducing the number of infections, the economic burden associated with the disease can be alleviated.

Authors: Simbar Masoumeh , Mahboubi Mohaddese , Nazarpour Soheila , Majd Hamid Alavi , Kiani Zahra , Fakari Farzaneh Rashidi , Khorrami Mobina , Keyvanfar Sepideh , Saberi Naiereh
Published: December 2024

Objective:

Premenstrual syndrome (PMS) is a combination of physical and psychological
symptoms that start during the luteal phase. There are no specific effective and safe remedies to relieve
these symptoms. However, there is a great tendency to use herbal medicines instead of chemical
medicines. This study aimed to assess and compare the effects of a soft gel capsule containing Pimpinella
anisum, Oenothera biennis, and Salvia sclarea oils (POS) with control, before and after use in two
consecutive cycles, on physical and psychological symptoms of PMS.

Methods:

This was a triple-blind randomized clinical trial performed on 67 female students, who were
residents in dormitories of the Shahid Beheshti University of Medical Science in Tehran, Iran. The participants
were randomly divided into two groups: soft gel capsule users containing POS as the intervention
group (n=32) and sunflower as the control group (SF) (n=35). The participants were 18-35 years
old female students who were affected by PMS. The capsules were used twice daily, from the 21st day
of the menstrual cycle to 2 days after the menstruation, for two consecutive menstrual cycles. The tools
for data collection were three questionnaires: a personal information questionnaire, a valid and reliable
daily PMS symptom report (DSR) form, and a side effects assessment questionnaire. The physical, psychological,
and general symptoms of PMS were assessed by the DSR, and the results were taken before
and after intervention and between groups of the study.

Results:

Before and after the intervention, the comparison showed significant effectiveness of POC in
reducing general, physical, and psychological symptoms after the first and second months of use. However,
the comparison of the groups did not show a significant difference between the two groups regarding
their PMS symptoms and the side effects of the medicines (p<0.05).

Conclusion:

POS is a combination of three herbal medicines effective on the symptoms of premenstrual
syndrome, which can be used effectively and safely to improve the physical and psychological symptoms
of premenstrual syndrome. This herbal remedy can be recommended by health care providers to
women, who suffer from PMS symptoms and prefer to use herbal remedies instead of synthetic drugs.
Further studies are necessary to evaluate the combined herbal remedies as well as the effectiveness of
sunflower oil on PMS symptoms.

A Cross-Disciplinary Analysis of the Complexities of Scaling Up eHealth Innovation
Authors: Allers Sanne , Carboni Chiara , Eijkenaar Frank , Wehrens Rik
Published: December 2024

Innovative eHealth technologies are becoming increasingly common worldwide, with researchers and policy makers advocating their scale-up within and across health care systems. However, examples of successful scale-up remain extremely rare. Although this issue is widely acknowledged, there is still only a limited understanding of why scaling up eHealth technologies is so challenging. This article aims to contribute to a better understanding of the complexities innovators encounter when attempting to scale up eHealth technologies and their strategies for addressing these complexities. We draw on different theoretical perspectives as well as the findings of an interview-based case study of a prominent remote patient monitoring (RPM) innovation in the Netherlands. Specifically, we create a cross-disciplinary theoretical framework bringing together 3 perspectives on scale-up: a structural perspective (focusing on structural barriers and facilitators), an ecological perspective (focusing on local complexities), and a critical perspective (focusing on mutual adaptation between innovation and setting). We then mobilize these perspectives to analyze how various stakeholders (n=14) experienced efforts to scale up RPM technology. We provide 2 key insights: (1) the complexities and strategies associated with local eHealth scale-up are disconnected from those that actors encounter at a broader level scale-up, and this translates into a simultaneous need for stability and malleability, which catches stakeholders in an impasse, and (2) pre-existing circumstances and associated path dependencies shape the complexities of the local context and facilitate or constrain opportunities for the scale-up of eHealth innovation. The 3 theoretical perspectives used in this article, with their diverging assumptions about innovation scale-up, should be viewed as complementary and highlight different aspects of the complexities perceived as playing an important role. Using these perspectives, we conclude that the level at which scale-up is envisaged and the pre-existing local circumstances (2 factors whose importance is often neglected) contribute to an impasse in the scale-up of eHealth innovation at the broader level of scale.

Stock Price Prediction System LSTM Based on Deep Learning
Authors: Pan Xizi
Published: December 2024

Stock price prediction is a highly complex task due to the inherent volatility and non-linear patterns of financial markets. Recent advancements in deep learning, particularly Long Short-Term Memory (LSTM) networks, have yielded promising results in time series forecasting. This paper provides an in-depth analysis of LSTM models applied to the stock price prediction of major technology companies, including Apple (AAPL), Tesla (TSLA), Microsoft (MSFT), and Nvidia (NVDA). The study utilizes historical stock data to train and evaluate LSTM models, comparing their performance against various other regression models such as Linear Regression, Support Vector Regression (SVR), Decision Tree Regression, and Gradient Boosting Decision Trees (GBDT).The results demonstrate that the LSTM model outperforms traditional models, particularly in its ability to capture long-term dependencies and manage complex, volatile stock data. Among the companies analyzed, the LSTM model achieved the most accurate predictions for Apple, as indicated by the lowest Mean Squared Error (MSE). Tesla's predictions, while less accurate due to high volatility, still showed improvement compared to other models. In conclusion, the LSTM network proved to be the most effective method for stock price prediction in this study, particularly excelling in forecasting long-term trends and reducing prediction errors for volatile stocks.
Discourse Analysis of Attitude Resources in News Discourse from the Perspective of Appraisal Theory: A Case Study of The Economists and Allafrica on the Belt and Road Initiative
Authors: Zhang Aoran
Published: December 2024

Using the attitude system within the framework of appraisal theory, this study collected news reports on the “Belt and Road” initiative published in 2023 by the UK’s The Economists and Africa’s Allafrica platform. The study analyzed the attitude resources expressed in these reports and compared the similarities and differences in attitude expression between the two. The research found that in terms of the polarity of attitude resources, The Economists predominantly used negative resources, primarily expressing concerns and doubts about the BRI, but also affirming the initiative to a certain extent. On the other hand, Allafrica predominantly used positive resources, emphasizing the positive contributions of BRI to the economic development and infrastructure construction of African countries. Despite the significant differences in the use of attitude resources between the two media, both conveyed their specific attitudes toward the initiative through the frequent use of judgment resources and appreciation resources. This difference reflects the positions and perspectives of media from different national and cultural backgrounds in reporting on international economic cooperation.
Research on the Impact of Altitude Hypoxia on Cognitive Function and the Enhancement of Hyperbaric Oxygen Intervention
Authors: Xu Qing
Published: December 2024

People's cognitive function is significantly influenced by the hypoxic environment at high altitudes. As elevation increases, reaching a certain threshold can exacerbate this effect. Hyperbaric oxygen therapy (HBOT) is a treatment for hypoxic conditions that involves breathing pure oxygen or high-concentration oxygen in an environment with pressure exceeding one atmosphere. Research has shown that HBOT can enhance cognitive function; however, there are limited studies focusing on individuals living in plateau regions. Compared to the low pressure and hypoxia experienced in lowland areas, HBOT offers greater therapeutic benefits in plateau regions. This paper summarizes the research on the impact of hypoxic environments on cognitive function at high altitudes and reviews the advancements in hyperbaric oxygen interventions. The aim is to explore the effectiveness of HBOT and to develop a research framework for optimizing oxygen dosage, which holds practical significance for promoting the health and well-being of people living in plateau areas.

Após pouco mais de duas décadas da entrada em vigor do Código Civil de 2002, está-se diante da possibilidade de importantes alterações em seu texto, devido a anteprojeto de lei de iniciativa da Presidência do Senado Federal. Significativas modificações contemplam, por exemplo, o direito digital e a proteção da mulher vítima de violência doméstica. Por outro lado, o anteprojeto se revela como um ponto negativo ao insistir na manutenção da invisibilidade das famílias simultâneas. O presente artigo pretende demonstrar que a omissão no enfrentamento da questão sob o ponto de vista legislativo, colide frontalmente com a interpretação inclusiva que vem sendo promovida para as entidades familiares através das normas constitucionais. O relatório final apresentado pela comissão de juristas nomeada pelo Senado não dá margem ao reconhecimento das famílias simultâneas em nenhum aspecto na lei civil brasileira. E que pode, a princípio, parecer coerente diante das recentes decisões proferidas pelo Supremo Tribunal Federal e que versam sobre o tema é, na verdade, desconforme à proposta de Estado desenhada pelo legislador constituinte, estruturada na justiça social e na dignidade da pessoa humana.
O ABUSO DE DIREITO NA DEVOLUÇÃO DE CRIANÇAS NO CURSO DO ESTÁGIO DE CONVIVÊNCIA E SUAS CONSEQUÊNCIAS
Authors: Baptista Virgínia Neves
Published: December 2024

O presente artigo, construído a partir da análise do instituto da adoção no direito brasileiro e seu respectivo procedimento, visa demonstrar as consequências atinentes à devolução de uma criança pelo pretendente à adoção, no curso do estágio de convivência. Sob a perspectiva do menor, analisam-se as implicações decorrentes do seu retorno a um abrigo, uma indiscutível situação de reabandono. No que diz respeito ao pretendente à adoção, a análise se concentra na caracterização da devolução do menor como ato ilícito, na forma de abuso de direito, contrapondo-se ao exercício regular de um direito, tal como previsto no art. 187 do Código Civil, encontrando-se na ambiência da responsabilidade civil o locus para a solução dos conflitos dele decorrentes. Através da constatação de que, dentre as finalidades da adoção, está a de garantir à criança o seu pleno desenvolvimento através da convivência familiar, onde formará vínculos de afetividade e afinidade, propõe-se uma reflexão sobre a ocorrência de danos existenciais e irreversíveis sobre aquele que, já desamparado e desassistido, se virá obrigado experenciar mais uma vez o abandono.
Compaixão, saúde e comunidade na esfera pública
Authors: Soneghet Lucas Faial
Published: December 2024

O presente artigo discute o discurso da compaixão na literatura contemporânea da saúde, com ênfase em textos sobre o lugar da compaixão nas práticas de saúde e textos sobre a abordagem de saúde pública chamada “comunidades compassivas”. O objetivo é identificar e caracterizar uma política da compassividade e do sofrimento a partir desses discursos. Os textos são selecionados a partir de buscas nas bases Latin American and Caribbean Health Sciences Literature e PubMed e interpretados de acordo com as questões propostas pelo artigo, isto é, a relação entre compaixão, saúde e esfera pública. No primeiro conjunto de textos, destacam-se formas de categorização e mensuração da compaixão na assistência em saúde, e uma terapêutica compassiva. Em confluência com tendências de medicalização e profissionalização, argumenta-se que a compaixão pode ser um novo modo de definição de problemas como do domínio da “saúde” e, portanto, facilita a aparição das especialidades da saúde na esfera pública. Notam-se tentativas de tornar a compaixão um índice mensurável e inteligível do ponto de vista científico, especialmente de acordo com padrões metodológicos das ciências da saúde. Então, desenha-se uma “terapêutica da compaixão” na qual esta parece ser o ingrediente faltante e a possível solução para uma série de problemas sociais além da doença. No segundo conjunto de textos, destaca-se a articulação entre compaixão e comunidade, por meio da qual generaliza-se uma política de compassividade centrada na perda e na morte como experiências universais. Aqui, a terapêutica da compaixão se generaliza e se articula com uma constelação de ideias relativas ao “comunitário” como nível de intervenção em saúde e de organização sociopolítica. Por fim, discute-se as ambiguidades e tensões internas em uma possível política de compaixão e comunidade diante do sofrimento.
Onde impera o medo: socioeducação, violência e afetos hostis no Rio de Janeiro
Authors: Camatta Clara , Lowenkron Laura , Mallart Fábio
Published: December 2024

A proposta do presente artigo é refletir sobre o modo pelo qual a violência no cotidiano de uma instituição de internação socioeducativa é exercida por meio de afetos hostis. Esses afetos expressam relações de poder que separam, hierarquizam e diferenciam determinados atores institucionais, bem como são elementos garantidores de humanidade. Para tanto, apresenta-se uma etnografia realizada em uma unidade de internação socioeducativa masculina do Rio de Janeiro, o Centro de Socioeducação Dom Bosco, analisando a partir do corpo de mulher branca da pesquisadora, entendido como “fora de lugar” nesta instituição, as condições de entrada e circulação no espaço. Serão examinados ainda os modos de habitar essa instituição e as possibilidades e limites de relação com cada ator institucional, especialmente os jovens internos e os agentes socioeducativos. No percurso etnográfico, ficam evidentes as formas de violência sutil exercidas na instituição por meio de afetos hostis, seja na construção de uma atmosfera de medo, nojo e/ou desprezo. Afetos esses experimentados tanto nas relações entre os diversos sujeitos que transitam pela internação quanto destes com o espaço de privação de liberdade. Desse modo, revela-se como tais afetos participam e são instrumentos de uma gestão de fluxos, própria às dinâmicas das instituições de confinamento.
Pengaruh Populasi, Jumlah Pemotongan, Hasil Produksi Ternak terhadap Produk Domestik Bruto (PDB), dan Penanaman Modal Dalam Negeri (PMDN)

Latar Belakang: Pembangunan peternakan berkelanjutan menjadi hal utama terhadap faktor pengembangan peternakan. Pengembangan usaha peternakan berkaitan langsung dengan populasi ternak di Indonesia. Populasi ternak harus mampu menjadi faktor keberhasilan pengembangan peternakan. Peternakan harus mampu menghasilkan populasi ternak unggul serta dapat meningkatkan pendapatan. Fakta bahwa populasi ternak berhubungan erat dengan investasi, telah ditunjukkan untuk potensi dan peluang investasi dapat meningkatkan nilai usaha peternakan. Dalam beberapa tahun terakhir, sub sektor peternakan di Indonesia mengalami peningkatan yang signifikan dalam investasi. Seperti yang ditunjukkan oleh data Statistik Peternakan dan Kesehatan Hewan 2023, PDB Peternakan tahun 2022 sebesar Rp178,1 triliun (atas harga konstan) atau meningkat 6,24% dari PDB Peternakan tahun 2021 sebesar Rp298,0 triliun (atas harga berlaku), memberikan kontribusi 16,51% terhadap PDB Sektor Pertanian. Selain itu, hasil realisasi investasi PMDN Peternakan pada tahun 2022 sebesar Rp3,9 triliun atau meningkat 82,74% (terjadi peningkatan dibandingkan dengan tahun sebelumnya). Artinya bahwa besaran nilai PDB dan PMDN dipengaruhi juga oleh besaran nilai kontribusi sub sektor peternakan di Indonesia. Tantangan sub sektor peternakan yaitu mampu mencukupi kebutuhan sumber daya ternak yang lebih besar dan perlu adanya perluasan infrastruktur di bidang peternakan. Ada pengaruh hubungan antara pembangunan peternakan berkelanjutan dengan jumlah populasi ternak. Jika populasi ternak tinggi maka dapat meningkatkan produktifitas peternakan. Reviews: Tulisan ini akan mengulas secara singkat terkait di sub sektor peternakan yaitu Pengaruh Populasi, Jumlah Pemotongan, Hasil Produksi Ternak terhadap Produk Domestik Bruto (PDB), dan Penanaman Modal Dalam Negeri (PMDN)

Published: December 2024

Latar Belakang: Daging ayam broiler merupakan makanan mengandung gizi tinggi sehingga mudah mengalami kerusakan karena kandungan gizi tinggi merupakan media pertumbuhan dan perkembangan mikroorganisme. Tujuan: Tujuan penelitian untuk menentukan lama pendinginan menggunakan refrigerator sebelum peyimpanan beku mempengaruhi kualitas fisik (pH, daya ikat air dan susust masak) daging dada ayam broiler. Metode: Penelitian ini menggunakan rancangan acak lengkap (RAL) 4 perlakuan dengan 5 pengulangan. Perlakuan penelitian adalah pendinginan daging dada ayam sebelum dibekukan yaitu tanpa didinginkan langsung dibekukan (P0), 2 jam pendinginan P1, 4 jam pendinginan P2, 6 jam pendinginan (P3). Pengukur kualitas fisik meliputi pH, daya ikat air dan susut masak. Data yang diperoleh dianalisis dengan sidik ragam (ANOVA) dan hasil berpengaruh nyata dilanjutkan dengan Duncan’s Multiple Range Test (DMRT). Hasil: Perlakuan pendinginan mempengaruhi nilai pH, daya ikat air dan susut masak secara nyata (P < 0,05). Pendinginan dalam refrigerator sebelum peyimpanan beku menghasilkan nilai pH tertinggi, daya ikat rendah dan susut masak tertinggi pada perlakuan P0 (tanpa pendinginan). Kesimpulan: Lama proses pendinginan daging dada ayam broiler dalam refrigerator sebelum penyimpanan beku mengakibatkan penurunan nilai pH, meningkatkan daya ikat air dan menurunkan susut masak. Pendinginan dalam refrigerator selama 6 jam sebelum peyimpanan beku mampu menghasilkan nilai pH, daya ikat air dan susut masak masih dalam kisaran kualitas fisik daging ayam broiler yang baik.
