Published: June 2024

Jumlah penduduk yang terus bertambah setiap tahunnya mengakibatkan kebutuhan akan bawang merah juga semakin meningkat sehingga petani harus terus meningkatkan produksi bawang merah baik dalam aspek kuantitas maupun kualitas. Agar dapat tumbuh dengan baik, bawang merah harus ditanam pada suhu dan kelembaban tanah yang sesuai. Pemberian nutrisi dan obat (fungisida) juga akan berpengaruh penting terhadap keberhasilan pertumbuhan bawang merah. Namun sering kali petani bawang merah dihadapkan pada beberapa masalah yang muncul seperti cuaca ekstrim yang berdampak buruk pada pertumbuhan tanaman bawang merah. Selain itu pemberian nutrisi dan obat yang tidak teratur dan tidak terkontrol juga mengakibatkan tanaman bawang merah tidak tumbuh dengan baik sehingga produksi semakin menurun. Berdasarkan hal tersebut maka pada penelitian ini dilakukan pembuatan prototipe smart greenhouse berbasis Internet of Things (IoT) untuk sistem monitoring dan kontrol pertumbuhan tanaman bawang merah. Pada greenhouse ini, aktivitas pengontrolan suhu, penyemprotan, pengairan, dan pemberian obat dapat dilakukan secara otomatis sehingga mempermudah pekerjaan para petani bawang merah. Komponen yang dipakai pada sistem yaitu mikrokontroler arduino dan ESP32,  sensor DHT22 sebagai pengatur suhu, sensor soil moisture Yl-69 sebagai pengontrol kelembaban tanah, sensor pH tanah untuk mengontrol nutrisi yang ada pada tanah, RTC DS3231 untuk penjadwalan penyemprotan, dan servo sg-90 untuk pemberian obat, dan seluruh data dapat diakses melalui aplikasi Blynk. Hasil pengujian sistem menunjukkan bahwa error sensor DHT22 memiliki rata rata 0,5%, error soil moisture berada pada nilai 0,8% dan error pada sensor pH berada pada nilai 0,36%. Hal ini mengindikasikan bahwa prototipe greenhouse untuk bawang merah dapat bekerja dengan baik.

Functional medical integration for chronic migraine management
Authors:   Korean Institute for Functional Medicine, Lee Sang-Hoon , Kim Sang Man
Published: June 2024

Chronic migraine, affecting approximately 2% of the global population, markedly diminishes quality of life and imposes significant
societal costs, surpassing the impacts of episodic migraine. Conventional medical treatments leave about 30% of patients with
persistent chronic migraine, some of whom fluctuate between episodic and chronic migraine states. A holistic, functional medicine
approach may provide supplementary benefits for these individuals. Clinical imbalances often identified in chronic migraine
patients—such as mitochondrial dysfunction, oxidative stress, gut microbiota dysbiosis, leaky gut syndrome, food intolerance,
histamine syndrome, vitamin D deficiency, and autonomic nervous system imbalances—can be detected through specific functional
medical assessments, including urine organic acid profiles, hair tissue mineral analysis, hydrogen breath tests, comprehensive
blood tests, and heart rate variability tests. Integrative functional medical interventions, encompassing lifestyle modifications,
oral and intravenous nutrition therapies, and the comprehensive 5R program (remove, replace, reinoculate, repair, rebalance)
for gut health, could offer therapeutic benefits. This review delves into the functional medicine paradigm and its potential
role in managing chronic migraine.

ABSTRAKSI
Untuk mengetahui kinerja keuangan sebuah perusahaan kita bisa menggunakan laporan keuangan. Pengukuran laporan dapat menggunakan rasio dan analisa common size. Informasi tentang perubahan komposisi dalam struktur modal dan komposisi investasi dapat diketahui melalui analisis laporan keuangan. Sedangkan untuk menilai tepatnya atau tidak tepatnya kebijakan operasi, pendanaan, dan investasi dari masa lalu ataupun masa depat dapat diketahui dengan common size. Kali ini peneliti akan menggunakan PT ACE Harware untuk dinilai pencapaian kinerja keuangan dalam perusahaan tersebut. Teknik deskriptif kuantitatif ialah metode yang digunakan. Sedangkan data sekunder yang dipakai ialah laporan keuangan periode 2019-2021 oleh PT. ACE Hardware. Menurut hasil penelitian, laporan keuangan neraca memperlihatkan kondisi finansial PT. ACE Hardware sudah cukup baik dalam mengoptimalkan aktiva serta memiliki struktur modal yang aman. Adapun, jika dilihat dari laporan laba rugi menunjukan dalam 2 tahun terakhir yaitu tahun 2021 dan 2020 perusahaan mengalami penurunan dari segi penjualan sebesar 11,7% pada tahun 2021 dan 9,0% pada tahun 2020 serta laba usaha sebesar 1,7% pada tahun 2021 dan 28,55% pada tahun 2020 jika dibandingan dengan tahun 2019. Penyebab utama penurunan ini adalah menurunnya jumlah transaksi yang terjadi di gerai akibat pandemi Covid-19, terutama varian Delta yang menyebabkan ditutupnya sejumlah gerai Perseroan di bulan Juli dan Agustus 2021. Sehingga kinerja perusahaan terbilang cukup kurang baik mengingat penurunan yang terjadi dalam tahun tersebut.

Authors: Tan Thuy Tran
Published: June 2024

Sleep disorders are becoming increasingly complex in today’ssociety. Analyzing sleep structure provides valuable information aboutsleep types, sleep cycles, and variations in different stages. However, manual sleep stage classification is challenging and time-consuming, limitingits clinical use. Deep learning methods have demonstrated promise forautomated sleep stage classification, but they face challenges such asclass imbalance and the need for interpretability. This paper investigatesthree deep learning methods, TinySleepNet, TS-TCC, and CA-TCC, using the Expanded Sleep-EDF dataset. We evaluate the performance ofthese methods and propose methods to address the aforementioned challenges. Our results show that deep learning methods can achieve highaccuracy for sleep stage classification, especially with the proposed enhancements. We also developed a sleep stage classification tool based onmethods.

Docsteach.Gov From The National Archives
Authors: Hussey Michael
Published: June 2024

Over the last 20 years, digital scanning technology and the Internet have combined to provide educators with access to a huge volume of primary source material. The National Archives' Archival Research Catalog ARC) alone contains over 150,000 digital images of documents, photographs, maps, and other records (http://www.archives.gov/research/arc/). This treasure trove is a wonderful resource although in some ways frustratingly rich.     Teachers in need of a good, teachable document probably do not have time to wade through an electronic mountain of digitally scanned primary sources. If they have found a primary source, they might be stuck on how to use it in the classroom. The National Archives' new website DocsTeach (http://docsteach.org/) offers a solution. It combines a large, growing, but easily searchable database of over 4,000 of the Archives' most teachable documents with a dynamic set of interactive activity-building tools. The primary sources contain historical content, and the interactive tools offer a means of developing students' historical and critical thinking skills.
Mapping decision-making pathways: Determination of intervention entry points for diagnostic tests in suspected serious infection
Authors: Naseem Raasti , Howe Nicola , Pretorius Sara , Williams Cameron , Lendrem Clare , Pallmann Philip , Carrol Enitan D ,   PROTECT study team
Published: June 2024

Background PROTECT (Platform Randomised evaluation of clinical Outcomes using novel TEChnologies to optimise antimicrobial Therapy) has brought together a team of researchers to design a platform trial to rapidly evaluate and adopt into care multiple diagnostic technologies, bringing immediate benefit to patients. Rapid diagnostic tests will be used to identify patients at risk of deterioration from severe infection, before they become critically unwell. The platform will assess their comparative clinical and cost-effectiveness relative to current standard of care. Preliminary work, conducted under a Health Technology Assessment Application Acceleration Award, provided key evidence to optimise the design of the PROTECT platform. Methods Qualitative methods which involved consulting key stakeholders in the field of serious infection addressed the key priorities. A high-level care pathway analysis focusing on serious infection in secondary care, captured the points of contact, actions, decisions, and potential outcomes associated with a patient’s care. Results Two use cases of rapid diagnostic tests for serious infection were identified; (1) in acute emergency medicine to decide on antimicrobial initiation and/or escalation of care, and (2) in hospitalised patients to monitor treatment response. Within the emergency department, clinicians believed a test would be used as an adjunct to existing standard of care and would be used to either rule-in or rule-out serious infection. The “ideal” test should be rapid, point-of-care, cheap to procure, have capacity for high usability, and ability to be performed and interpreted by all staff. Facilitators to the adoption of infection diagnostic tests is their clinical need, and the main potential barrier is poor change management and behavioural change. Conclusions Any new test should provide robust evidence of its effectiveness and have the potential to benefit the clinical pathway for patients, clinicians, and hospitals as a whole, to be considered for adoption as a new standard of care.

Authors: Paul Shubhra Prakash , Das Porimal Kumar , Shaha Dhiman , Miah Mamun , Akhter Rawshan Jahan , Hoque Mahbubul , Chowdhury M A K Azad
Published: June 2024

Background: Complications from preterm birth are the leading causes of death among children under 5 years of age, responsible for approximately 1 million deaths in 2015. Three-quarters of these deaths could be prevented with current, cost-effective interventions. Premature infants, particularly those born at <28 weeks of gestation, are at significant risk for reduced bone mineral content (BMC) and subsequent bone disease, variably termed metabolic bone disease (MBD), osteomalacia, osteopenia, or neonatal rickets. Risk of fracture and growth failure increase in the presence of osteopenia in these infants. Early detection of Osteopenia of Prematurity (OOP) may prevent unwanted deaths.
Objectives: To identify biochemical markers of osteopenia in the neonatal period for early detection before the appearance of radiological evidence of osteopenia.
Methods: This prospective observational study was carried out at Dhaka Shishu Hospital (DSH) from July, 2016 to June, 2018. Babies admitted in the Neonatal Intensive Care and Special Care Baby Unit with gestational age <34 weeks and birth weight <2200 gm were included in the study. Purposive sampling technique was used to collect the study data. Blood sample for baseline biochemical markers were collected in 1st week of life, then subsequently at 2 weeks interval up to corrected term age. Wrist radiography was done for to detect radiological osteopenia at 6th week post-natal age and at corrected term age. Then the biochemical parameters are compared with radiological osteopenia.
Result: This study included 84 preterm new born below 34 weeks of gestation and a birth weight below 2200 grams. Radiological evidence of osteopenia of prematurity was found in 34 (40.5%) babies of which 29 (85.3%) were below 32 week and 5 (14.7%) were at or above 32 weeks. Osteopenic infants had significantly (p<0.001) lower birth weight (1318.82 ± 264.23 gm) compared to non-osteopenic infants (1701.40 ± 431.11 gm). Our study showed that the optimal cutoff point for Alkaline phosphatase (ALP) was 352.50 U/L at 3rd week of life, at which sensitivity and specificity were found 82.4% and 80.0% respectively. Serum inorganic phosphate values for the diagnosis of osteopenia was 4.67 mg/dl at 5th week of age. At this level, sensitivity was found to be 68.0%, whereas specificity was 60.0%. Serum calcium of the infants did not show any significant difference when they were enrolled in the study and in the first follow up. But serum calcium level was significantly lower in osteopenic infants compared to nonosteopenic infants in 2nd and 3rd follow up (p<0.05).
Conclusion: High alkaline phosphatase level at 3rd week of life and low serum inorganic phosphate at 5th week of life can be used as a predictor of osteopenia of prematurity.

Textile waste consists of insoluble solid particles, salts, dyes and heavy metals and is very difficult to degrade. Chitin derived from shrimp waste has the potential to overcome textile waste in chitin that causes environmental pollution through more economical absorption and easily available raw materials. Factors that improve adsorption performance include pH and temperature. This study was conducted to determine the effect of temperature, pH, and a combination of temperature and pH treatments on the ability of chitin to adsorb textile dye waste. The parameters observed were temperature, pH, combination of temperature and pH, functional groups (FTIR), chitin structure (SEM), and heavy metal test (AAS). Data analysis of statistical test results using two-way Analysis of Variance (ANOVA) followed by Duncan's further test. The ANOVA test results showed that the incubation treatment of temperature, pH, and a combination of different temperature and pH treatments resulted in (p < 0.05). This shows that incubation temperature and pH have an effect (significantly different) on the adsorption of chitin as an adsorbent on dyes. The results of Duncan's test showed that the best chitin adsorption was obtained in temperature incubation at 50°C (A3), incubation at pH 3 (B1), and the best combination adsorption at 50°C and pH 3 of 1,091±0.007a ppm.

Lempuk fish is a native Indonesian fish that is endemic in the Ranu Grati tectonic lake, Pasuruan Regency, East Java. This research aims to provide information in efforts to domesticate lempuk fish, especially on reproductive aspects related to the microscopic characteristics of gonads and reproductive type of Lempuk fish (Gobiopterus sp). This research uses the primary sexual characteristics method with gonadal histology. The variables observed included the male to female sex ratio, the histological structure of male and female gonads, and the reproductive type of lempuk fish. All data was analyzed descriptively, qualitatively and quantitatively by comparing with related literature. The samples taken in this research were 39 Lempuk Fish (Gobiopterus sp). The samples were then preserved in 10% formalin. The number of samples for histological analysis was 20 individuals, while for morphometric and meristic analysis there were 8 individuals. The results of the research show that morphologically the lempuk fish has a transparent body shape and there is a central line on the body with black or brown pigment and has a total length of around 2-3 cm. Lempuk fish have a type of reproduction that develops asynchronously (asynchronous) because the development of oocytes in the ovaries of female fish shows a variety of developmental stages, namely the initial growth stage (nuclear and perinuclear chromatin), cortical alveolar, vitellogenesis, and the mature stage. The sex ratio is predominantly female with a ratio of 0.64: 0.36. The histological structure of male and female gonads has histological differences that reflect different reproductive functions, where the ovaries play a role in egg cell production, while the testes are responsible for sperm formation. An imbalance in the sex ratio indicates the importance of carrying out domestication steps in order to prevent extinction or continuous population decline.

Limited agricultural land has caused a decline in the productivity of green mustard (Brassica juncea L.) as one of the nutritious vegetables that is widely consumed by the public. Cultivating vegetables using a hydroponic wick system is a solution to increase the productivity of green mustard. The expensive price of nutrient solutions can be combined with eco enzymes as a provider of essential nutrients for plants. This research aims to determine the effect of the combination of AB mix with eco enzyme on the growth of green mustard. The research was designed with RAL, 8 treatments, and 3 replications. Treatments include A1E0=AB mix 100%+0mL/L eco enzyme, A1E1=AB mix 100%+1mL/L eco enzyme, A1E2=AB mix 100%+2mL/L eco enzyme, A1E3=AB mix 100%+3mL eco enzyme, A2E0=AB mix 75%+0mL eco enzyme, A2E1=AB mix 75%+1mL/L eco enzyme, A2E2=AB mix 75%+2mL/L eco enzyme, and A2E3=AB mix 75%+3mL/L eco enzyme. The parameters measured were plant height, number of leaves, wet weight of roots and shoots, dry weight of roots and shoots, and leaf area. Data were analyzed using analysis of variance and DMRT testing with α=0.05. The combination of AB mix with eco enzyme had no effect on plant height, number and area of leaves, and wet weight of roots and shoots. However, the highest dry weight of roots and shoots in the A2E2 treatment showed significantly different results from the control treatment (A2E0). Eco enzymes act as nutrient substitutes which are influenced by sunlight, plant metabolism and water absorption capacity.

Teluk Nibung River in Batu Ampar District, Kubu Raya Regency is a transportation route for Mangrove Production Forests and a traditional fishing area for local communities. The community structure of phytoplankton in the Teluk Nibung River has never been reported. As the main producer in the waters food chain, the structure community of phytoplankton indicates the quality of the fertility of the waters. The community structure of phytoplankton can be identified by measuring the index of abundance, diversity, evenness and dominance. The survey method was used at three stations in dry and rainy seasons. Sample collection is using net plankton (30 µm) and preserved in 4% formalin. The physico-chemical factors measured included temperature, pH, brightness, current velocity, salinity, dissolved oxygen and CO2, phosphate and nitrate. Once identified, phytoplankton calculations are performed to obtain abundance, diversity, evenness, and dominance values. The species number of phytoplankton found was 56 classified into 6 classes, namely Bacillariophyceae (34 species), Dinophyceae (12 species), Chlorophyceae (4 species), Cyanophyceae (3 species), Xantophyceae (1 species), and Euglenophyceae (2 species). The highest abundance of phytoplankton was in the Bacillariophyceae class with a range of 583 Ind./L at Station 2 in the rainy season to 3.922 Ind./L at Station 3 in the dry season. The diversity index at the three stations and both seasons is in the moderate category with a range of 2.31-2.46. The evenness index at the three stations and both seasons is in the high category with a range of 0.67-0.73. Low dominance level was found at the three stations and both seasons with values ranging from 0.14 to 0.19. Overall, the community structure of the phytoplankton in the Teluk Nibung River is in relatively good condition and can support the life of the aquatic biota in it.
