Mangrove plants are one of the plants that really help aquatic ecosystems between the sea, coast, and land. Mangrove plants provide many ecological, social, and economic benefits. In Indonesia, mangrove plants have 202 species with the same anatomy as other plants in general, consisting of roots, fruits, stems and leaves. Nowadays, the location of mangrove plants in Indonesia has experienced the fastest damage in the world due to conversion to ponds, settlements, industry and plantations. One of the efforts to restore aesthetic value and restore the ecological function of mangrove forest areas is rehabilitation using mangrove fruit. In the rehabilitation process, farmers generally use the manual method with the naked eye to determine fruit ripeness on mangrove plants, so the resulting level of accuracy is not optimal. To overcome this problem, an application is needed that can facilitate farmers in determining fruit maturity in mangrove plants so that it can help determine the maturity level of mangrove fruit. The development of this application utilizes the Deep Learning method as well as the utilization of digital image processing techniques with Grayscaling, Adaptive Threshold, Sharpening and Smoothing techniques. The results of this study are an application that can detect the level of fruit maturity in mangrove plants with an accuracy of 99.11%. With this application, determining the maturity level of fruit on mangrove plants can be easily done.

Authors: Knight LaTisha N. , Royal Kenneth D. , Robertson James B.
Published: March 2023

The purpose of this study was to describe the perceived preparedness for performing cataract surgery of veterinary ophthalmology residents’ who are currently enrolled in, or recently graduated from, veterinary academic or private practice institutions. A descriptive survey was distributed online to 127 residents at academic and private practice training programs in the United States. The survey included items about educational resources available for residents and techniques commonly taught during cataract surgery. Residents were asked to describe their perceived preparedness in performing various surgical steps or techniques, difficulty of each surgical step, and the available educational resources. Thirty-five (27.5%) residents completed the survey and were included in this study. Residents who had access to wet labs gained surgical competency in creating a clear corneal incision, capsulorhexis, and wound closure. They reported sculpting with the phacoemulsification handpiece, quadrant or cortical removal, and capsulorhexis as most difficult and were not as prepared or a little prepared in performing capsulorhexis and sculpting during active phacoemulsification. When comparing residents’ perceived competency before and after their first surgical experience, there was a significant change in their ability to perform all surgical steps except hydrodissection ( p < .05). Cataract surgery is one of the more advanced surgical skills obtained during residency training. Supervised wet lab time improves a resident’s preparedness for executing certain surgical steps. However, further research is needed to determine whether educational resources such as structured curriculum or virtual simulation may improve residents’ preparedness for executing surgical steps not easily replicated in a wet lab.
To the Rescue: First Responders and Medical(ized) Bodies inFin-de-SiècleVienna
Authors: Obermüller Alexander
Published: March 2023

Founded in 1881, the Wiener Freiwillige Rettungs-Gesellschaft (WFRG) sought to provide first aid to city dwellers in fin-de-siècle Vienna. This article analyzes how first responders established themselves as intermediaries between patients and the medical clinic and sought legitimacy from authorities as medical professionals. First responders contributed to processes of medicalization, widely shared information on patients, and readily deferred to police at a time of rapid change. Drawing on Viennese newspapers and the WFRG’s annual reports and daily logbooks, the author shows how first responders dealt with public scrutiny, conscripted themselves into the fight against malingerers, and joined authorities in administratively surveying and morally policing patients’ bodies. In their quest to gain social and professional legitimacy, first responders’ medicalizing practices and deference to existing authorities went hand in hand.

Baghdad Vehicle Traffic Congestion: Case Study
Authors: MOHAMMED ALİ Salim , AL-HEMİARY Emad
Published: March 2023

Vehicles contribute a considerable amount of green gas emission to the environment. Methods of calculating such emission using conventional measuring tools do not give an accurate future estimation as the number of vehicles increases, since there are many factors that affect the estimation such as traffic delays. Therefore, a different approach is should be considered in measuring road networks traffic capacity for a specific region, especially when the numbers of vehicles change dramatically during rush hours. Furthermore, the amount of fuel consumption wastage during traffic delays cannot be easily calculated based of on the number of vehicles solely. In this paper, a comprehensive study is made to examine and to calculate the effect of traffic congestion in Baghdad city of Iraq in terms of: pollution, fuel consumption, and time cost, using the road network simulator of SUMO. Several scenarios are considered with randomly selected paths for each vehicle. In this study, several empirical equations are extracted from the simulation test results. As a result, an aberration is observed in fuel consumption and traffic delays while exceeding 100 thousand vehicle capacity for the whole city of Baghdad. However, the interpolated equations can be used to approximately measure the traffic metrics for higher number of vehicles for the same city.

Authors: Morgillo Amelia , Marovino Edoardo , Mazzarella Marcello , Merandi Serena , Giordano Lucia , Morgillo Caterina Rosaria , Cambareri Angela , Temporini Caterina
Published: March 2023

INTRODUCTION. Many crimes, especially of a sexual nature, are committed using sedative substances to reduce the victim's state of consciousness and reactivity and are defined as "drugs facilitated crimes". Among these, benzodiazepines (BDZ) and some new designer derivatives are widely used especially in liquid formulations added to other drinks. The purpose of this article is to analyze the chemical, toxicological and analytical characteristics starting from the alteration data and through in-depth analysis on dedicated databases.

MATERIALS AND METHODS. We conducted searches in PUBMED, PUBCHEM, CHEMID PLUS and GOOGLE SCHOLAR for papers and documents done on qualitative characteristics of the BDZ most commonly used as facilitating crimes. We have selected research articles and reviews from 2012 to 2022, with the primary endpoint relative to the typology of BDZ found in the samples examined in the various studies. We also researched their chemical and toxicological characteristics on the PUBCHEM and CHEMID PLUS international databases.

DISCUSSION AND CONCLUSIONS. Benzodiazepines (BDZs) are among the most commonly used sedatives for illicit purposes, including their use to facilitate sexual crimes or robbery, alone or in co-administration with other substances, especially alcohol. In recent years there have been recorded cases of both classic BDZ intoxication, marketed as medicinal specialties, but also of new designer BDZs such as cinazepam, flualprazolam or phenazepam, less easily detectable in first-level toxicological tests and often much more potent than other more commonly used compounds. The analytical techniques in use, especially the first-level assays used in triages, can sometimes fail to cross-react and make these molecules invisible which, even in the most sophisticated confirmation tests such as techniques combined with mass spectrometry, do not always make these new psychoactive substances detectable.

The present study aimed to evaluate the effect of the combination between nitrogen rates and the management of straw mulches for the cultivation of peppers. The treatments comprised three managements of straw on the ground (no straw, Urochloa ruziziensis, and millet) and five nitrogen rates (0, 50, 100, 150, and 200% of the recommended dose of 120 kg ha-1). Mulch presence results in better physiological activity in the plants, while the rates of N positively affect the physiological and biometric characteristics of the plants up to 127.50% and 181.21%, respectively. Rates up to 145.62% increased fruit length in the treatment composed of U. ruziziensis straw, while rates relative to 154.65%, 127.98%, and 138.55% for the control, U. ruziziensis and millet treatments provided productive gains of 202.52%, 267.44%, and 473.18%. We concluded that straw mulching improves the physiological condition of sweet pepper plants and the application of nitrogen fertilizer; using straw from millet plants, combined with the dose of 138.55% N, results in greater yield gains.

Published: March 2023

ABSTRAK           Inflasi dapat mengakibatkan kesenjangan sosial yang tinggi ditengah-tengah masyarakat. Oleh karena itu, indikator dari inflasi perlu diselidiki untuk memberikan sinyal dan masukan kepada pemberi kebijakan dan kepada masyarakat secara luas. Oloko dkk. pada tahun 2021 menemukan bahwa Harga emas dan tingkat inflasi terkointegrasi pada nilai tukar yang yang berfluktuasi menengah atau memiliki batasan dibandingkan dengan nilai tukar yang berfluktuasi bebas dan tetap. Selain itu, hubungan antara tingkat inflasi dengan pengangguran dijelaskan oleh kurva philips, namun hal ini mendapatkan bantahan dari penelitian yang dilakukan oleh Zayed dkk, (2018). Lebih lanjut Goh dkk. (2022) menemukan bahwa Hubungan fluktuasi harga minyak bumi dan inflasi di Indonesia tidak memiliki hubungan linear baik searah maupun terbalik. Hasil dari penelitian dari artikel ini menemukan bahwa berbeda dengan pendapat Goh (2022) dan Zayed (2018), tingkat pengangguran dan harga minyak tidak memiliki pengaruh yang signifikan terhadap fluktuasi tingkat inflasi. Namun, selaras dengan temuan Oloko (2021), hasil olah data dari penelitian ini berhasil menemukan adanya hubungan yang signifikan antara harga emas dengan fluktuasi inflasi pada tingkat kepercayaan alpha dibawah 10%, yang merupakan batas interval kepercayaan yang masih bisa diterima pada penelitian-penelitian sosial.Kata Kunci : Harga, Emas, Minyak, Inflasi, Pengangguran ABSTRACT  Inflation can cause a huge social gap among the society. Therefore, there should be an inquiry for the inflation indicators that can give a signal and insights to the policy maker and to the public at  large. Oloko et.al (2021) has found that Gold price and inflation rate is cointegrated to the exchange rate that fluctuate in a controlled fluctuation rather than exchanges that is pegged strictly or fluctuates freely. Besides that, the relationship between unemployment and inflation rate is explained by the philips curve, but recently a research conducted by Zayed (2018) has found that the situation which occurs in the Philipines are quite different than what is explained by the philip's curve. Furthermore, Goh et.al (2022) found that the relationship between oil price and inflation rate in Indonesia are not linier both unidirectional or reverse. This article has found a different results than the results that come from Goh (2022) and Zayed (2018), unemployment rate and oil prices did not have a significant influences towards the inflation rate. However, in line with Oloko findings in 2021, the results of data processing from this research has successfully concluded a significant relationship between gold price and inflation rate fluctuation at a confidence interval below 10%, which is an interval that is still accepted on social research.  Keyword : Prices, Gold, Oil, Inflation, Unemployment

Tanaman sengon merupakan salah satu  jenis tanaman yang banyak dikembangkan di hutan rakyat,  karena daur totasi relatif pendek dan produktivitas kayu yang baik. Pola penanaman monokultur telah menyebabkan tanaman sengon mudah terserang hama dan penyakit. Salah satu penyakit yang menyerang tanaman sengon adalah karat tumor yang disebabkan adanya infeksi dari jamur Uromycladium tepperianum Sacc. Oleh karena itu perlu dilakukan pengamatan  seragan karat tumor terhadap pertumbuhan tanaman sengon. Pengamatan serangan karat tumor dilakukan di hutan rakyat Desa Pait, Kabupaten Malang dengan membuat sebanyak sepuluh plot pengamatan secara tersebar. Hasil studi menunjukkan bahwa intensitas serangan karat tumor pada  plot pengamatan mencapai  100%. Serangan karat tumor pada tanaman sengon ditandai dengan adanya tumor pada ujung ranting dan cabang tanaman. Rata-rata pertumbuhan diameter tanaman berkisar antara  10,8 cm sampai  21,6 cm. Sedangkan rata-rata pertumbuhan tinggi mencapai  7 m pada umur 2 tahun dan 16 meter pada umur  4 tahun. Secara umum  pertumbuhan tanaman sengon tidak terpengaruh oleh adanya serangan karat tumor. Namun demikian serangan bisa berkembang lebih lanjut ke batang tanaman yang dapat menyebabkan terganggunya metabolisme pertumbuhan tanaman.. Beberapa upaya yang dapat dilakukan untuk mengatasi serangan karat tumor ini antara lain dengan melakukan sanitasi,pemberantasan secara  mekanik dan penggunaan fungsisida.

Erupsi Gunung Merapi terjadi secara periodik yang menyebabkan tanah selalu terbarui setelah terjadinya erupsi. Faktor ketinggian tempat menjadi salah satu faktor penyebab adanya perbedaan ketebalan timbunan material vulkanik yang berupa pasir, kerikil dan bebatuan. Akibat dari perbedaan tersebut berpengaruh terhadap perbedaan vegetasi penutup lahan terutama pada bagian atas yang didominasi oleh jenis invasif Acacia decurren. Penelitian ini untuk mengetahui jenis-jenis makrofauna tanah dan membandingkan kekayaan (DMg), keanekaragaman (H’) dan keseragaman (E) spesies di dalam dan di luar tegakan pada lahan pasca erupsi Gunung Merapi tahun 2010. Penelitian dilakukan di Kawasan Kalikuning Park yang berada di Taman Nasional Gunung Merapi (TNGM) dengan menggunakan metode hand sorting. Pembuatan plot ukur setiap lokasi sebanyak 6 buah yang dibagi menjadi 3 buah di dalam tegakan dan 3 buah berada di luar tegakan. Pengukuran kondisi lingkungan yang dilakukan pengukuran kelembaban, suhu, kecepatan angin, intensitas cahaya, suhu tanah, pH dan bahan organik tanah. Hasil penelitian menunjukkan bahwa vegetasi penutup menyebabkan adanya perbedaan keberadaan dan distribusi makrofauna tanah. Jenis yang ditemukan seperti cacing, Rhizotrogus aequinoctialis, Rhizotrogus marginipes, laba-laba, lenyai, kelabang, kaki seribu, semut hitam, semut merah dan yellow mealworm. Pada lokasi di dalam tegakan memperoleh nilai DMg= 3,27, H’= 2,739, E= 1,038. Lokasi di luar tegakan memperoleh nilai DMg= 2,04, H’= 1,99, E= 0,961

Rafflesia patma is one of endangered species in Indonesia. It is nature population was currently decreasing due to Rafflesia patma holoparasitic nature, whose existence depends on its host (Tetrastigma sp). Pangandaran Nature Reserve is one of areas which has become the habitat of Rafflesia patma in Indonesia. This study aimed to know the suitability of ecological and social habitat for Rafflesia patma in Pangandaran Nature Reserve. The Spatial Multi Criteria Analysis (SMCA) had been done using ecological and social conditions approach that influencing the existence of Rafflesia patma. Parameters of ecological conditions used were the presence of Rafflesia patma, host, predators, and water source. While the social conditions used were the center of human activity and accessibility. Each parameter was scored and overlaid into a map of the suitability of ecological and social conditions. Scoring in each parameter based on a literature study. The result showed that there were three classes of suitability for ecological and social conditions. Location with the most suitable result was 52,5 ha or 12,52%, suitable 176,5 ha 42,09%, and that did not suitable for the ecological and social conditions was 190,3 ha or 45,39%. Location with the most suitable conditions for Rafflesia patma habitat spread in the area which was an ecotone of coastal forest and lowland forest. Based on these results, the management of Pangandaran Nature Reserve need to pay more attention to the ecological habitat of Rafflesia patma. In addition, restrictions on community activities also need to be carried out in order to minimize habitat disturbance by the surrounding community.
