The article discusses the need for measures to improve the hydrological regime of the Kuban water basin, taking into account climate change, namely, mathematical modeling of the hydraulic conditions for conjugation of the pools of the spillway structure of the Krasnodar reservoir and ways to improve the hydrological regime of the river. Pshish and Kuban. The Krasnodar reservoir at high water levels in the rivers changes the feeding boundaries for groundwater in the protected area, and at low low water levels they are drains. When water levels in the reservoir are less than 29 m (this is a low water level in the Pshish River in the area of the transverse dam), its influence on the protected area practically ceases, since the coastline of the Krasnodar reservoir recedes from the transverse dam far to the northwest, exposing earlier flooded riverbed. Due to the increasing climatic changes in the south of Russia, namely, the constant decrease in the water level in the Caucasus mountains from year to year has led to a deterioration in the hydraulic regime throughout the entire Kuban water basin. From year to year, there is a deterioration in the situation, which leads to deformation processes in the channel of a very unpredictable river. Kuban, which will further contribute to the development of lowering the water level in relation to the initial data at the time of design and construction of the reservoir. There was a danger of violation of the hydraulic conditions for the conjugation of the pools of the spillway structure – ensuring the necessary conjugate depth of the perfect hydraulic jump and, consequently, preventing it from jumping out of the water well. In the latter case, catastrophic consequences would have occurred. The Kuban is the longest and most abundant river in the Greater Caucasus. this is the main water artery of the western and northwestern part of the northern slope of the Greater Caucasus Range and the southern part of the western Ciscaucasia, carrying its waters through four regions of southern Russia: the Krasnodar and Stavropol Territories, the Karachay-Cherkess Republic and the Republic of Adygea. The Krasnodar reservoir creates the necessary water level support on the rivers – tributaries, which, when the maximum water flow passes, can spread to the river. Pshish for 10-12 km.

The purpose of the study is to assess the conditions forensuring the protection of fish from entering water intakes when using water intake buckets. The article analyzes the possibilities of protecting fish in conditions of use of water intake buckets, which, depending on the hydrological characteristics of the water source, taking into account changes in water levels and flow rates, as well as water protection requirements and sanitary and epidemiological conditions, provide the required conditions for water supply. The possibilities of ensuring the protection of fish when using water intake buckets are considered on the example of three designs from different water sources, of which only in one condition the protection of fish can be assessed as satisfactory. At the same time, the need for additional implementation of measures to remove fi sh from the bucket is a determining condition for the success of their conservation. However, this presents the greatest difficulty, which is currently not solved in the layout of bucket water intakes, including foreign practice. As possible fish protection devices for the conditions of water intake buckets, the designs are considered which use the effect of hydraulic flushing and diversion, in particular filtering, louvering, etc. Based on the results of the analysis of hydraulic conditions in the bucket, a scheme for the formation of a fish diverting stream with subsequent movement along the fish drainage tract beyond the influence of the water intake bucket is considered.

Limbah kain perca merupakan limbah anorganik yang memerlukan perhatian khusus dalam penanganannya dengan tujuan untuk keberlanjutan lingkungan. Metode yang sering digunakan dalam pengelolaan limbah adalah 3R (Reduce, Reuse, Recycle). Dari teknik pengolahan Reuse kemudian berkembang menjadi upcycling yang lebih menekankan kepada peningkatan nilai manfaat material. Dalam bidang interior, kain perca di-upcycling menjadi pembungkus busa untuk dudukan dan sandaran pada kursi flat-pack. Konsep dasar pembuatan kursi flat-pack adalah pemanfaatan limbah kardus yang disusun sedemikian rupa sehingga terbentuk kursi yang dapat digunakan pada ruangan interior seperti ruang tamu dan ruang keluarga. Kemudian konsep pembuatan bahan ini dikembangkan dengan menggunakan papan MDF yang lebih keras dan kokoh. Untuk lebih memberi kenyamanan pada kursi, perlu ditambah busa yang dibungkus kain. Teknik sambungan yang digunakan dalam menyambung kain perca berupa patchwork, quilting, dan applique. Untuk mempercantik produk dan sekaligus sebagai identitas pembuatan, dapat menambahkan teknik sablon, baik sablon manual ataupun sablon digital.Fabric waste is inorganic waste that requires special treatment in its handling with the aim of environmental sustainability.

KAJIAN BENTUK POLA PERSEBARAN PERMUKIMAN PESISIR DI KECAMATAN MORO, KEPULAUAN RIAU
Authors: Aguspriyanti Carissa Dinar , Helen - , Sudiana -
Published: November 2022

Studi ini mengkaji bentuk pola persebaran permukiman pesisir di Kecamatan Moro, Kepulauan Riau, khususnya di bagian selatan Pulau Sugi Bawah. Hal ini dikarenakan kondisi wilayahnya yang semakin padat dengan pembangunan yang cenderung tidak beraturan, beresiko menurunkan kualitas permukiman yang ada di sana, dan merusak lingkungan sekitar. Padahal Kecamatan Moro dikenal kaya akan kearifan lokal kuliner, seni, dan budaya. Dengan menggunakan metode interpretasi visual dari gambaran muka bumi (Google Earth), studi kualitatif deskriptif ini menemukan bahwa terdapat dua bentuk pola persebaran antara lain pola memanjang dan pola lompatan katak. Sebagai pola utama, pola memanjang dapat ditemukan di sepanjang zona perbatasan darat dan air, serta di beberapa wilayah pada zona daratan. Sedangkan pola lompatan katak hanya ditemukan di beberapa titik lokasi pada zona daratan. Walaupun dinilai tidak efektif, pola tersebut memungkinkan adanya ruang-ruang terbuka di kawasan permukiman dan berpotensi menjadi katalis pembangunan di area lain yang belum padat. Terbentuknya kedua pola tersebut di permukiman pesisir ini dipengaruhi oleh beberapa faktor seperti mata pencaharian penduduk yang menuntut kemudahan akses terhadap perairan, kedekatan dengan pelabuhan, kemudahan akses terhadap jalan utama atau sekunder, dan keinginan dari penduduknya sendiri.---------------------------------------------------------------------------------------------This study analyses the distribution pattern of coastal settlements in Moro District, Riau Islands, particularly in the southern part of Sugi Bawah Island. It is because the condition of the area is increasingly dense with the development that tends to be irregular and at risk of reducing the quality of the settlements, as well as damaging the surrounding environment. Whereas Moro District is known to be rich in local wisdom such as culinary, art, and culture. By using the visual interpretation method of the earth's surface (Google Earth), this descriptive qualitative study found that there are two forms of distribution patterns, namely linear pattern and leap frog pattern. As the main pattern, the linear development pattern can be found along the land and water boundary zones, as well as in some areas of the land zone. Meanwhile, the leap frog pattern was only found in a few locations in the mainland zone. Although considered ineffective, this pattern allows for open spaces in the settlement areas and has the potential to be a catalyst for development in other areas that are not yet crowded. The formation of these two patterns in coastal settlements was likely influenced by several factors such as the livelihoods of the residents who demand easy access to waters, proximity to ports, easy access to main or secondary roads, and the wishes of the residents themselves.

Optimization Ground Glass Opacities (GGO) Detection Using Multipixel Interpolation Techniques
Authors: Yanto Musli , Yogi Wiyandra
Published: November 2022

Ground Glass Opacities (GGO) are a picture of abnormal lung conditions characterized by white or gray areas. This picture of GGO in the lungs could previously be detected based on the results of medical examinations such as Computerized Tomography (CT scan) and Magnetic Resonance Imaging (MRI) images of patients suffering from Covid-19. However, from the results of the examination, it can be seen that the CT scan and MRI images still have a noise level that is too high, causing difficulties in describing the distribution pattern of the GGO itself. The purpose of this study was to optimize the detection of GGO on MRI images using the Multipixel Interpolation technique. The detection process adopts several stages including image preprocessing, edge detection process, and gradient morphological segmentation. Image preprocessing is done to remove noise and improve the MRI input image. The edge detection process is carried out to detect lung organs automatically using the Canny method which is optimized with the multipixel interpolation technique. The final stage of the research is the segmentation process using a gradient morphology technique to see the spread of GGO in patients with Covid-19 contained in the MRI image. The results of this study present an overview of the GGO pattern with fairly good results. The results of the GGO pattern description will also measure the level of spread to see the severity of pneumonia. Based on the results presented, this research is useful as an alternative solution in the process of diagnosis and treatment of Covid-19 patients.
Periodic and almost periodic solutions of the Riccati equations with linear reflecting function
Authors: Belokursky M. S.
Published: November 2022

The method of Mironenko’s reflecting function is used for investigation of Riccati equations. The class of Riccati equations with certain-type reflecting function has been preliminarily constructed. The necessary and sufficient conditions, under which the Riccati equation would have a reflecting function linear in phase variable, are proved. These conditions are constructive in nature, since on their basis the formula is obtained, which shows the linear in phase variable reflecting function in terms of the coefficients of the Riccati equation. Additionally, the relationship between the parity (oddness) property of the coefficients of the Riccati equation and the existence of a reflecting function linear in phase variable is investigated. The application of the method of Mironenko’s reflecting function to the constructed class of Riccati equations revealed sufficient conditions, under which all its solutions are periodic or almost periodic. A sign of no periodic solutions for almost periodic Riccati equations is obtained. An example of the quasi-periodic Riccati equation with quasi-periodic reflecting function, which has a periodic solution, is given.

Photon density of states effect on Lamb shift in plasmas
Authors: Novitsky D. V. , Gaponenko S. V.
Published: November 2022

A possible effect of the low photon density of states in plasma on the Lamb shift is analysed. It is found that because of a significant contribution of high-energy virtual photons to the Lamb shift, its modification in plasma does not exceed 1 % with respect to vacuum even at electron concentrations as high as 1022 cm–3. This behavior results from an asymptotic tendency of plasma properties to vacuum ones at an unlimited frequency growth.

Authors: Aizberg R. E. , Gribik Ya. G. , Garetsky R. G.
Published: November 2022

In segmented paleorift systems such as the Pripyat–Dnieper–Donetsk aulacogen, which penetrate deep into the continent from the side of the paleoocean margin and most often close here, each segment represents an autonomous structure of the lithosphere. The presented article shows that the tectonic position of the Pripyat paleorift as the western closing segment of the indicated aulacogen was due to a change in the intensity of syn-rift and plate-tectonic processes in the extended rift system from east to west. In the band of the Paleoproterozoic Fenno-Sarmatian collision, the Central Belarusian suture zone of the Central Russian transpression belt isolated by S. V. Bogdanova in 2018 was a blocking transverse barrier to relative development of Hercynian synrift processes in the western direction.

Authors: Muhartono Rizky , Nurlaili
Published: November 2022

Jakarta merupakan daerah dengan wilayah yang dilintasi 13 sungai. Namun demikian, pada sungai-sungai tersebut kerap dijumpai sampah. Salah satu penghasil sampah di sungai (diduga) berasal dari limbah domestik masyarakat yang tinggal di bantaran sungai. Permasalahan utama yang diangkat adalah bagaimana masyarakat bantaran sungai peduli dengan tidak membuang sampah ke sungai. Salah satu tema penting yang dapat dilakukan sebagai konsep pemberdayaan masyarakat bantaran sungai adalah bersahabat dengan sungai. Program ini tidak bertujuan untuk mencegah banjir yang datang ke Jakarta tetapi konsep ini dimunculkan sebagai jawaban untuk melawan kebiasaan masyarakat bantaran sungai yang sudah terlanjur menganggapnya sebagai lahan milik pribadi sehingga dibolehkan membuang sampah di sungai. Memahami karakteristik masyarakat dan individu dengan mempertimbangkan unsur budaya dan norma setempat menjadi penting, sehingga hambatan program berupa rendahnya saling percaya dan minimnya inovasi dan kreativitas bisa diatasi.

Latar Belakang: Indonesia merupakan negara ke-3 dengan insidensi Tuberkulosis (TB) terbanyak di dunia. 15% kasus TB merupakan Extra Pulmonary TB (EPTB) dengan 50% kasus diantaranya merupakan Limfadenitis TB (LNTB). Gambaran histopatologi dari sampel biopsi yang diambil dari limfonodi terdampak memegang peran penting dalam diagnosis penyakit ini dengan mengasilkan gambaran Well Organized Granuloma (WOG) atau Poorly Organized Granuloma (POG). Jumlah leukosit dapat menggambarkan respon imun pada penderita LNTB.

Metode : Penelitian ini merupakan penelitian analitik observasional dengan metode pendekatan potong lintang. Data diperoleh dengan melakukan dokumentasi rekam medis pasien LNTB yang dirawat di Rumah Sakit Umum Daerah (RSUD) Provinsi NTB dan RSUD Kota Mataram dalan rentang waktu Januari tahun 2019 – Februari tahun 2020.

Hasil : Total subjek penelitian berjumlah 51 orang. Pada gambaran histopatologi, 37 sampel termasuk WOG dan 14 sampel termasuk POG. Pada jumlah leukosit, tidak ada pasien yang mengalami leukopenia, 39 pasien mempunyai jumlah leukosit yang normal dan 12 pasien mengalami leukositosis. Hasil dari uji korelasi Spearman didapatkan p = 0.005 dan r = 0.384

Kesimpulan : Terdapat hubungan yang bermakna antara gambaran histopatologi dengan jumlah leukosit pada penderita LNTB di NTB pada Januari 2019 –  Februari 2020. Korelasi tersebut bersifat lemah.

Prolaps organ panggul (POP) adalah turun atau menonjolnya dinding vagina ke dalam liang vagina atau keluar introitus vagina, yang dapat disertai oleh organ-organ pelvik (uterus, kandung kemih, usus atau rektum). POP menimbulkan rasa ketidaknyamanan (uncomfortable feelings) pada penderitanya, gejala-gejalanya meliputi gejala vagina, buang air kecil (BAK), buang air besar (BAB), dan seksual. Meskipun demikian, POP sering kali tidak terdeteksi pada stadium dini atau bersifat asimtomatik sehingga pasien sering kali berobat pada stadium lanjut. Laporan kasus ini melaporkan seorang perempuan multipara berusia 58 tahun dengan sistokel grade IV, prolaps uteri grade IV, dan rektokel grade IV yang mendapat terapi pembedahan total vaginal hysterectomy dan high levatorplasty.

Mola Hidatidosa merupakan salah satu kasus yang jaring terjadi. Penegakan diagnosis mola harus dilakukan segera dan tepat karena dapat menjadi ganas dan bisa menimbulkan kegawatan dikarenakan perdarahan yang banyak. Kami melaporkan seorang wanita usia 43 tahun hamil 11 minggu dengan keluhan perdarahan pervaginam. Kasus ini menarik karena pasien memiliki faktor resiko yaitu berusia 43 tahun. Pada pemeriksaan vagina ditemukan adanya darah, ostium uteri eksternum terbuka dan tinggi fundus uteri teraba seperti usia kehamilan 24 minggu. Pemeriksaan titer ?-hCG urin positif sampai 1/400 dan pemeriksaan ultrasonografi abdomen ditemukan gambaran “snowstorm appearance” tanpa janin. Diagnosis mola hidatidosa komplit dan kemudian dilakukan kuretase. Jaringan yang terkumpul diambil untuk di lakukan pemeriksaan histopatologi. Tidak ada komplikasi selama dan setelah tindakan kuretase. Pasien pulang dalam kondisi baik dan sehat.

Authors: Gia Halidagia Reksadita Lugina
Published: November 2022

Latar Belakang: Indonesia merupakan negara dengan beban infeksi Mycobacterium tuberculosis  tertinggi bersama 48 negara lainya. Sekitar 60%-90% kasus infeksi Mycobacterium tuberculosis  menyerang kelenjar getah bening di regio servikal (Mirsaeidi & Sadikot, 2018). Penggunaan metode fine needle aspiration biopsy (FNAB)  pada pemeriksaan terhadap pembesaran kelenjar getah bening merupakan teknik invasif minimal yang akurat.

Metode : Penelitian ini merupakan penelitian analitik observasional dengan metode pendekatan total sampling. Data diperoleh dengan melakukan dokumentasi rekam medis pasien limfadenitis tuberkulosis yang dirawat di RSUD Provinsi NTB dalam rentang waktu Janari– Desember tahun 2019. Subjek penelitian berjumlah 50 pasien. Analisis dilakukan dengan uji hipotesis korelatif Spearman menggunakan SPSS 25,0.

Hasil : Total subjek penelitian berjumlah 50 orang dengan rincian 5 pasien dengan gambaran sitologis tipe-1,  20 pasien dengan gambaran sitologis tipe-2, dan 25 pasien dengan gambaran sitologis tipe-3. Korelasi gambaran sitologis dengan pembesaran nodus limfe dan penurunan berat badan sebesar <0,005 sedangkan dengan respon terapi berupa demam menunjukan nilai >0,005.

Kesimpulan : Terdapat hubungan yang bermakna antara gambaran sitologi dengan pembesaran nodus limfe dan penurunan berat badan setelah mengonsumsi OAT selama minimal 6 bulan, sedangkan hubungan gambaran sitologi dengan kejadian demam menunjukan hasil yang tidak signifikan.

Latar Belakang: Kualitas Hemodialisis (HD) merupakan salah satu faktor prediktor mortalitas dan morbiditas pasien PGK stadium 5. Dengan meningkatkan adekuasi dari HD yang dapat dinilai dari kecukupan dan efektivitas dosis, maka akan mengurangi komplikasi dan efek samping pada organ tertentu. Salah satu komplikasi yang dapat ditimbulkan adalah malnutrisi. Tujuan penelitian ini adalah untuk mengetahui hubungan antara adekuasi HD dengan status gizi pasien yang menjalani HD pada pasien PGK stadium 5.

Metode: Penelitian ini dilakukan pada bulan Agustus hingga September 2020 di Unit HD RSUD Kota Mataram. Desain penelitian yang digunakan adalah metode cross-sectional dengan consecutive sampling dan melibatkan 51 sampel yang memenuhi kriteria inklusi dan eksklusi. Pengumpulan data dilakukan dengan pencatatan data rekam medis pasien yang menjalai HD di RSUD Kota Mataram. Adekuasi HD dinilai dengan melihat Kt/V pasien dan status gizi dinilai dengan menggunakan parameter IMT dan kadar albumin serum pasien. Uji korelatif yang digunakan adalah uji korelasi Spearman untuk mengetahui hubungan antar variabel.

Hasil: Pada penelitian ini didapatkan rata-rata usia responden adalah 55,1 tahun dan terdiri dari 51% pria dan 49% wanita. Pada hasil analisis korelatif dengan menggunakan uji korelasi spearman, didapatkan hubungan adekuasi HD dengan IMT pasien adalah p=0.967 dan r=0.006. Untuk hubungan adekuasi HD dengan kadar albumin serum adalah p=0.662 dan r=0.063.

Simpulan: Tidak terdapat hubungan yang signifikan secara statistik antara adekuasi HD dengan status gizi pasien yang dinilai dengan parameter IMT dan kadar albumin serum pasien.
