Authors: PAMUKÇU Umut , BAĞCI Nuray , PEKER İlkay
Published: December 2021

Abstract

The eruption of an odontoma is extremely rare. It may be associated with some complications such as pain, inflammation of the adjacent soft tissues and delayed eruption of permanent teeth. In this study, we presented three erupted odontoma cases and a review of the literature in this regard. All our cases were male aged 21, 23, and 80 years old. Two patients had symptoms such as swelling, purulent flow, and pain, while one was asymptomatic. In the literature research, we found 66 published papers that describe 74 cases between 1989-2020. Dentists should pay attention to erupted odontoma because of serious complications.

Özet

Odontomanın sürmesi oldukça nadirdir. Ağrı, çevredeki yumuşak dokuların iltihaplanması ve kalıcı dişlerin gecikmiş sürmesi gibi bazı komplikasyonlarla ilişkili olabilir. Bu çalışmada, sürmüş üç odontoma vakası ve bu konudaki literatürün gözden geçirilmesi sunulmuştur. Olgularımızın tamamı 21, 23 ve 80 yaşında erkeklerdi. İki hastada şişlik, pürülan akıntı ve ağrı gibi semptomlar varken, biri asemptomatikti. Literatür araştırmasında, 1989-2020 yılları arasında 74 vakayı anlatan 66 yayınlanmış makale bulduk. Diş hekimleri, ciddi komplikasyonlar nedeniyle sürmüş odontomaya dikkat etmelidir.
‘ALL-ON-FOUR ‘ , ‘ALL-ON-FIVE’ ve ‘ALL-ON-SIX’ KONSEPTi KULLANILARAK ÜRETİLEN PROTEZLERİN STRES DAĞILIMININ SONLU ELEMANLAR ANALİZ YÖNTEMİ İLE İNCELENMESİ

Amaçlar: Bu çalışmanın amacı; tam dişsiz üst çenede All-on-Four, All-on-Five ve All-on-Six tekniğine göre yerleştirilmiş implantlar üzerine yapılan protezlerin 3 boyutlu modellerinin kemik, implant elemanları ve protetik elemanlar üzerinde oluşturduğu stresleri sonlu elemanlar analiz yöntemi ile değerlendirmektir. Gereç ve Yöntem: Tamamen dişsiz atrofik maksillada, All-on-Four, All-on-Five ve All-on-Six konseptine göre üç farklı tedavi planı oluşturulmuştur. En posterior implantlar bütün gruplarda premolarlar bölgesinde, distale doğru 30 derece eğimli olarak konumlandırılmıştır. Alt yapı; krom-kobalt (Cr-Co) alaşımından kesilmiş diş formunda, üst yapı ise monolitik zirkonya olarak ayrı ayrı modellenmiş, daha sonra kontakt noktalarından temas sağlanmıştır. Protez kantilever uzunluğu 10mm olarak sabit tutulmuştur. Kuvvetler; palatobukkal yönde 45° açıyla, 3,4,5,6 no’lu dişlere sırasıyla; 100N, 150N, 150N, 200N olacak şekilde çift taraflı olarak uygulanmıştır. Von Misses, maksimum principal stres ve minimum principal stresler elde edilmiştir. Bulgular: All-on-Six konsepti sırasıyla kortikal kemikte, implant ve protetik elemanlar üzerinde ve spongiyöz kemikte daha düşük von Mises, maksimum principal ve minimum principal stres göstermiştir. Sonlu elemanlar analizinin sonuçlarına göre bakılan tüm parametrelerde protez altyapısındaki stress ve implantlardaki stres dışında en fazla von Misses stresine sahip olan konsept All-on-Four olarak görünmektedir. Sonuçlar: İmplant sayısı arttıkça implant elemanları ve protetik elemanlarda görülen stres azalmıştır ancak araştırılan 3 tedavi konseptinde de stres değerleri kemik direnci sınırlarını aşmadı. All-on-Six tedavi konseptinin, atrofik maksillanın rehabilitasyonunda All-on-Four ve All-on-Five konseptlerine göre daha iyi biyomekanik davranış sergilediği söylenebilir.
COVID-19 PANDEMİSİNİN DİŞ HEKİMLİĞİ ÖĞRENCİLERİNİN DİŞ HEKİMLİĞİNDE UZMANLIK EĞİTİMİNE BAKIŞLARINA OLAN ETKİSİ

Published: December 2021

AMAÇ

Çalışmamızda diş hekimliği öğrencilerinin COVID-19 pandemisi sürecinde hastalık kapma korkularının kariyer planları üzerine etkisi olup olmadığını ve yeni bir ana dal olarak açılan Oral Patoloji dalını seçmeleri üzerine etkisinin olup olmayacağını araştırmayı planladık.

GEREÇ VE YÖNTEMLER

Çalışmamızda oluşturulan anket formu Yakın Doğu Üniversitesi, Dr. Suat Günsel Girne Üniversitesi ve Erciyes Üniversitesi Diş Hekimliği fakültelerinde Türkçe eğitim programında halen öğrenim gören öğrencilerden 967’sine ulaştırılmış olup anket, demografik bilgileri sorgulayan üç soru ve öğrencilerin yönelimlerini iki seçenekli yanıtlar ile değerlendirmeyi hedefleyen 9 soru ile toplam 12 sorudan oluşturulmuştur.

BULGULAR

Çalışmamıza anket formunu eksiksiz dolduran 781 (% 80,8) öğrenci dahil edildi. Öğrencilerin % 87si COVID-19 pandemisi nedeniyle mesleklerini icra ederlerken eskiye kıyasla daha fazla bulaşıcı hastalık kapma korkusu yaşadıklarını belirttiler. Öğrencilerin % 77si bir diş hekimliği dalında uzmanlık eğitimi almayı planlamaktaydı ve bulaşıcı hastalık kapma korkusu yaşayanların % 24’ünün, hastaları ile daha az yakın temasta olacakları bir uzmanlık dalı arayışında olduğu görüldü. Bu öğrenciler arasında kadınların oranları anlamlı derecede yüksekti (% 26 – % 15, p=0,002). Diş hekimliğinde uzmanlık dalı olarak Oral Patolojiyi seçebileceğini belirten öğrencilerin oranı, COVID-19 pandemisi nedeniyle bulaşıcı hastalık kapma korkusu yaşadığını bildiren öğrenciler arasında anlamlı düzeyde yüksekti (p=0,021). Oral Patoloji dalını tercih edebilirim ve tercih etmem diyen öğrencilerin oral patoloji uzmanlık dalı hakkındaki bilgi düzeyleri bakımından anlamlı bir farklılık bulunamadı (p=0,161).

SONUÇ

COVID-19 enfeksiyonu ve bulaşıcı hastalık kapma korkusu, diş hekimliği öğrencilerinin uzmanlık dalı seçimi üzerine etki eden faktörler arasındadır. Bunun yanında, Oral Patolojiyi uzmanlık dalı olarak seçmeyi düşünen ve düşünmeyen öğrenciler arasında bu uzmanlık dalı hakkındaki bilgi düzeyleri bakımından fark bulunamamış olması, kaçınma eğilimli davranışların da diş hekimliğinde uzmanlık dalı seçimi üzerinde etkisi olabileceğini düşündürmektedir.

La traducción de lo indecible en «The Fall of the House of Usher» de Edgar Allan Poe y la traducción de Julio Cortázar

Published: December 2021

Cuando hablamos del fenómeno fantástico, los autores «solo» tienen el lenguaje como herramienta para describir lo imposible, lo que rompe con las reglas de lo establecido y subyace tras las palabras. Mientras el autor de relatos fantásticos debe recurrir al lenguaje de lo no existente, los traductores deben interpretar esos términos que evocan sensaciones y trasladarlos a la lengua meta, enfrentándose al reto de traducir lo indesignable, lo intraducible por no existente. Si la representación de lo imposible es el reto de los escritores de lo fantástico, la traducción de aquello será el reto de los traductores: Cómo traducir lo que no se puede ni designar en su lengua original.

En este artículo se ha trabajado la traducción de «The Fall of the House of Usher» de Edgar Allan Poe hecha por Julio Cortázar, escritor de lo fantástico además de traductor, prestando atención al léxico utilizado por escritor y traductor para representar lo imposible. Para la contextualización de lo fantástico y los límites del lenguaje se han seguido las líneas de David Roas, principalmente, y de otros autores, como Bozzetto, que han estudiado la retórica de lo fantástico.
Breves reflexiones sobre los problemas de la traducción en Jacques Lacan
Authors: Asensi Pérez Manuel
Published: December 2021

La traducción es una dimensión esencial en la obra de Lacan. En ella se conjugan la dificultad de traducir a otras lenguas su estilo manierista, y la práctica de la traducción llevada a cabo por el propio Lacan especialmente en relación a Freud, pero también respecto a otros autores como Poe, Sófocles, Platón, Joyce, y un largo etcétera. En este trabajo se ha tomado como punto de referencia tres conceptos que tienen una gran trascendencia dentro de la teoría lacaniana: unterdrückt, verdrängt y Verwerfung. Una de las tesis que se sostienen a lo largo de las páginas que siguen es que en la relación entre unterdrückt y verdrängt no solo se trata de un problema léxico o semántico, sino que la traducción está presente como uno de los elementos constitutivos del inconsciente. De ahí la importancia de ese tema. Por otro lado, el término Verwerfung planteó dos tipos de problemas: uno al propio Lacan cuando asimiló los textos freudianos, y otro a los traductores al español (o al inglés, etc.) de ese mismo término.
De "The Picture of Dorian Gray" de Oscar Wilde al "Dorian Gray" de Corominas: Análisis de una transducción interartística, ¿lograda?
Authors: De Buron Brun Benedicte
Published: December 2021

Partiendo del concepto de transducción interartística de Wellek, este artículo se propone llevar a la práctica el caso de The Picture of Dorian Gray de Oscar Wilde adaptado por Corominas. Un ejemplo de transducción interartística de lo más interesante y arriesgado tanto más cuanto que se trata de ofrecer un clásico literario de la Inglaterra del siglo XIX a un público visual, y no forzosamente de letras, en los albores del siglo XXI, mediante el Noveno Arte. Por otra parte, este álbum presenta otra originalidad y es que fue publicado y, de hecho, traducido al francés antes de ser editado en España, lo que duplica su transducción, en este caso, lingüística: Todo un reto, tanto para el dibujante y guionista Corominas como para la traductora Carole Rattclif.
La traducción literaria tiene la palabra
Authors: Richart Marset Mabel
Published: December 2021

Tomando como punto de partida la emotiva necrológica que el traductor literario Peter Bush le dedica a su colega de profesión, Helen Lane, nos adentramos en varios puntos clave de la traducción literaria: la traducción  como “el sistema circulatorio de las literaturas del mundo” (Sontag, 2007: 17), la figura del traductor y de la traductora como escritores y su fructífera colaboración con el autor o autora cuando esta sea posible, su indeseada y forzada invisibilidad en las obras que traducen y que ha originado campañas de concienciación reivindicativas de la talla de #namethetranslator y #TranslatorOnTheCover, el consumo de literatura traducida, etc. Al mismo tiempo se lleva a cabo una reflexión sobre el statu quo de la disciplina de los Estudios de Traducción: ¿Se está realmente produciendo un giro desde los Estudios de Traducción hacia los Estudios del Traductor?  ¿Estamos entrando o hemos entrado ya en la era de los Estudios de Post-Traducción?

The Impact of Deconstruction on the Lithuanian Literary Criticism
Authors: Jurgutienė Aušra
Published: December 2021

In the article I discuss how deconstruction (Jacques Derrida and other Yale School participants) came to Lithuanian literary criticism  and how it changed habits of humanitarian thinking during the three decades after independence. The most unusual and radical deconstruction critique of essentialist metaphysical thinking, new terminology (inter-text, elimination of center, footprint, writing, difference, blinding, labyrinth narrative, guest / enemy, etc.) and new strategies for interpreting texts were very important for Lithuanian humanities liberated from Soviet ideology.  Literary critics have noticed and discussed the undoubted connection between postmodernist literature and its deconstructive reading.We can find three tendencies in the deconstructive criticism of Lithuanian literature. The first tendency is the interpretation of general theoretical concepts of deconstruction, second tendency - searching the deconstructive features in literary works and the third tendency of criticism, expanding its own self-criticism and self-irony, is discussing chrestomathic and structuralist interpretations of the literary works or deconstructing icons of Soviet culture. We know very well, that many feminist, postcolonial, historiographic, anthropological, or interdisciplinary researches of literature cannot escape the effects of deconstruction.

Authors: Dargys Adolfas , Acus Artūras
Published: December 2021

Closed form expressions to calculate the exponential of a general multivector (MV) in Clifford geometric algebras (GAs) Clp;q are presented for n = p + q = 3. The obtained exponential formulas were applied to find exact GA trigonometric and hyperbolic functions of MV argument. We have verified that the presented exact formulas are in accord with series expansion of MV hyperbolic and trigonometric functions. The exponentials may be applied to solve GA differential equations, in signal and image processing, automatic control and robotics.

Authors: You Zhongli , Fečkan Michal , Wang JinRong , O’Regan Donal
Published: December 2021

In this paper, relative controllability of impulsive multi-delay differential systems in finite dimensional space are studied. By introducing the impulsive multi-delay Gramian matrix, a necessary and sufficient condition, and the Gramian criteria, for the relative controllability of linear systems is given. Using Krasnoselskii’s fixed point theorem, a sufficient condition for controllability of semilinear systems is obtained. Numerically examples are given to illustrate our theoretically results.
Finite-time stabilization for fractional-order inertial neural networks with time varying delays
Authors: Aouiti Chaouki , Cao Jinde , Jallouli Hediene , Huang Chuangxia
Published: December 2021

This paper deals with the finite-time stabilization of fractional-order inertial neural network with varying time-delays (FOINNs). Firstly, by correctly selected variable substitution, the system is transformed into a first-order fractional differential equation. Secondly, by building Lyapunov functionalities and using analytical techniques, as well as new control algorithms (which include the delay-dependent and delay-free controller), novel and effective criteria are established to attain the finite-time stabilization of the addressed system. Finally, two examples are used to illustrate the effectiveness and feasibility of the obtained results.
Global dynamics for a class of reaction–diffusion multigroup SIR epidemic models with time fractional-order derivatives
Authors: Lu Zhenzhen , Yu Yongguang , Ren Guojian , Xu Conghui , Meng Xiangyun
Published: December 2021

This paper investigates the global dynamics for a class of multigroup SIR epidemic model with time fractional-order derivatives and reaction–diffusion. The fractional order considered in this paper is in (0; 1], which the propagation speed of this process is slower than Brownian motion leading to anomalous subdiffusion. Furthermore, the generalized incidence function is considered so that the data itself can flexibly determine the functional form of incidence rates in practice. Firstly, the existence, nonnegativity, and ultimate boundedness of the solution for the proposed system are studied. Moreover, the basic reproduction number R0 is calculated and shown as a threshold: the disease-free equilibrium point of the proposed system is globally asymptotically stable when R0 ≤ 1, while when R0 > 1, the proposed system is uniformly persistent, and the endemic equilibrium point is globally asymptotically stable. Finally, the theoretical results are verified by numerical simulation.
Some critical remarks on “Some new fixed point results in rectangular metric spaces with an application to fractional-order functional differential equations”
Authors: Younis Mudasir , Stretenović Aleksandra , Radenović Stojan
Published: December 2021

In this manuscript, we generalize, improve, and enrich recent results established by Budhia et al. [L. Budhia, H. Aydi, A.H. Ansari, D. Gopal, Some new fixed point results in rectangular metric spaces with application to fractional-order functional differential equations, Nonlinear Anal. Model. Control, 25(4):580–597, 2020]. This paper aims to provide much simpler and shorter proofs of some results in rectangular metric spaces. According to one of our recent lemmas, we show that the given contractive condition yields Cauchyness of the corresponding Picard sequence. The obtained results improve well-known comparable results in the literature. Using our new approach, we prove that a Picard sequence is Cauchy in the framework of rectangular metric spaces. Our obtained results complement and enrich several methods in the existing state-ofart. Endorsing the materiality of the presented results, we also propound an application to dynamic programming associated with the multistage process.

Authors: Balaguer Máximo Roiz , Barrabia Ileana Morales
Published: December 2021

Introduction: Cerebrovascular Diseases (CVD) constitute one of the most important health problems on a global scale and in Cuba they occupy the third cause of death and the first cause of disability. Objective: To evaluate the use of atorvastatin in the acute phase of atherothrombotic cerebral infarction. Method: A prospective longitudinal study was carried out in patients who attended the on-call department of the Julio Trigo López Hospital and were diagnosed with acute atherothrombotic cerebral infarction, who were randomly administered with prior informed consent: 0, 20 mg or 40 mg of atorvastatin , they underwent CAT (Computerized Axial Tomography) of the skull, which was repeated on the third day and at 30 days, the value of PCR (C Reactive Protein) was determined in on-call body, on the fifth day and at 30 days, they were clinically evaluated according to the NIHSS scale (National Institute of Health Stroke Scale) in on-call body , daily during their admission and 30 days later. Results: The size of the infarct area decreased by 19.4% with 40 mg of atorvastatin as did the CRP value which was reduced by 16 mg/Ll. The clinical assessment (NIHSS scale) was reduced according to the dose of atorvastatin by slightly more than 8 points. Conclusions: The decrease in infarct area was directly proportional to the dose of atorvastatin used, just as the CRP values were lower and the favorable clinical evolution was associated with the use of this.
Refining the Pediatric Multiple Organ Dysfunction Syndrome

Published: December 2021

Since its introduction into the medical literature in the 1970s, the term multiple organ dysfunction syndrome (or some variant) has been applied broadly to any patient with >1 concurrent organ dysfunction. However, the epidemiology, mechanisms, time course, and outcomes among children with multiple organ dysfunction vary substantially. We posit that the term pediatric multiple organ dysfunction syndrome (or MODS) should be reserved for patients with a systemic pathologic state resulting from a common mechanism (or mechanisms) that affects numerous organ systems simultaneously. In contrast, children in whom organ injuries are attributable to distinct mechanisms should be considered to have additive organ system dysfunctions but not the syndrome of MODS. Although such differentiation may not always be possible with current scientific knowledge, we make the case for how attempts to differentiate multiple organ dysfunction from other states of additive organ dysfunctions can help to evolve clinical and research priorities in diagnosis, monitoring, and therapy from largely organ-specific to more holistic strategies.

Opus Dei e opus homini
Authors: Maciel Rafhael Silva
Published: December 2021

Este artigo trata da questão da liturgia entendida como obra de Deus e obra do homem, da relação entre os dois atores da celebração litúrgica. O artigo procura, com o auxílio da Constituição Sacrosanctum Concilium sobre a sagrada Liturgia, do Concílio Ecumênico Vaticano II, apresentar a relação e o encontro Deus-homem no contexto da celebração litúrgica. A reflexão é auxiliada por textos magisteriais dos últimos Pontífices e de alguns teólogo e liturgistas. O texto busca refletir sobre uma acurada e sã relação entre a liturgia enquanto tal e a aproximação do homem crente a essa realidade divino-humana. Na reflexão proposta aponta-se para a necessidade de que a celebração litúrgica seja o local do encontro do homem com Deus, no exercício do sacerdócio de Cristo – opus Dei, e no exercício do sacerdócio batismal – opus homini.

Data dianalisis dengan analisis varians (ANOVA). Hasil penelitian menunjukkan bahwa varietas ‘Manik’ and ‘Domba’ yang dipanen pada 20 HSBM memiliki kandungan kadar air dan antioksidan tertinggi sedangkan total karotenoid meningkat pada buah matang. Model kalibrasi dan uji validasi silang kadar air, total karotenoid, dan antioksidan mendapatkan nilai Rkal  ≥ 0,87 dan Rval  ≥ 0,84. Berdasarkan hasil tersebut, maka kandungan air dan antioksidan terbesar yaitu buah cabai rawit hijau sedangkan total karotenoid tertinggi pada buah cabai rawit merah. Vis/NIRS dapat digunakan untuk mendeteksi kandungan air, total karotenoid dan antioksidan pada buah cabai rawit. Generally, cayenne pepper is coloring in green, orange, and red. Each maturity level has a different quality.  A non-destructive technology, visible/near infrared spectroscopy (Vis/NIRS), has been widely used to predict the quality quickly and accurately without causing damage. The study aimed to determine water content, total carotenoids, and antioxidant of two varieties cayenne pepper with different maturity levels and to predict quality non-destructively using Vis/NIRS. The research was conducted at the Horticulture Laboratory, Agriculture Faculty, Universitas Padjadjaran. The research was arranged in a completely randomized design (CRD) with 6 treatments, namely ‘Manik’ and ‘Domba’ varieties harvested at 20 days after flowering (DAF), 40 DAF and 60 DAF, and 5 replications with analysis of variance (ANOVA). The results showed that ‘Manik’ and ‘Domba’ harvested at 20 DAF had the highest water content and antioxidant while the total carotenoids increased in ripe fruit. The calibration model and cross-validation of water content, total carotenoids, and antioxidants obtained values of Rcal 0.87 and Rval 0.84. Based on these results, the highest water and antioxidant content was green cayenne pepper, while the highest total carotenoids were in red cayenne pepper. Vis/NIRS can be used to detect water content, total carotenoids, and antioxidants in cayenne pepper.

Inceptisols umumnya memiliki tingkat kesuburan tanah rendah sampai sedang. Upaya peningkatan ketersediaan hara tanah Inceptisol dengan pupuk anorganik NPK perlu diimbangi dengan aplikasi pupuk hayati dan amelioran organik. Percobaan ini bertujuan untuk mengurangi dosis pupuk NPK dengan menggunakan pupuk hayati dan amelioran organik serta meningkatkan hasil tanaman jagung. Percobaan dilakukan di Pasir Banteng, Kabupaten Sumedang. Penelitian menggunakan RAK faktorial. Pupuk hayati dengan amelioran organik sebagai faktor pertama sebanyak empat taraf: tanpa pupuk hayati dan amelioran (kontrol), diberi pupuk hayati, amelioran organik, dan gabungan keduanya. Faktor kedua yaitu dosis pupuk NPK empat taraf: 100%, 80%, 60%, 40% NPK dosis anjuran.  Dilakukan tiga kali ulangan. Hasil penelitian menunjukkan terdapat interaksi antara pupuk hayati, amelioran organik, dengan pupuk NPK terhadap tinggi tanaman, N-total tanah, bobot tongkol berkelobot dan tanpa kelobot. Pemberian pupuk hayati dan amelioran disertai pupuk NPK 100% dan yang tanpa diberi amelioran menghasilkan bobot tongkol tanpa kelobot sebesar 1.089 g dan 1.064 g per tanaman. Pemberian pupuk hayati dengan amelioran dan pemberian pupuk NPK 100% menghasilkan bobot pipilan per tanaman 526,08 g dan 539,08 g. Aplikasi pupuk hayati dan amelioran organik belum mampu mengurangi dosis penggunaan pupuk NPK pada Inceptisols asal Pasir Banteng. Inceptisols generally have low to moderate soil fertility. The effort to increase the nutrients availability in Inceptisol through the application of NPK fertilizers need to be balanced with biofertilizers and organic ameliorants. This experiment aimed to reduce the dose of NPK fertilizer by using biofertilizers and organic ameliorants and to increase maizeyields. The experiment was conducted in Pasir Banteng, Sumedang Regency. The factorial RBD was used. The biofertilizer with organic ameliorant as the first factor: no biofertilizer and no ameliorant (control), biofertilizer, organic ameliorant, and combination of both. The second factor was dose of NPK fertilizer: 100%, 80%, 60%, 40% of recommended NPK dose. It was repeated three times. The results showed that there was interaction between biofertilizer, organic ameliorants, with NPK fertilizers on plant height, N-total soil, weight of cobs with and without husk. The application of biofertilizer and ameliorant with 100% NPK fertilizer and without ameliorant were 1,089 g and 1,064 g of cobs without husks, respectively. The application of biofertilizer with ameliorant and 100% NPK fertilizer had a grain weight of 526.08 g and 539.08 g, respectively. The application of biofertilizers and organic ameliorants has not been able to reduce the dose of NPK fertilizer on Inceptisols from Pasir Banteng.

Salah satu alat untuk peringatan dini tsunami, IDSL (Inexpensive Device for Sea Level Measurement) atau PUMMA (Perangkat Ukur Murah untuk Muka Air laut) yang merupakan sebuat stasiun pasang surut real-time telah terpasang di Pantai Pangandaran sejak Oktober 2019. Tulisan ini bertujuan untuk menganalisa kinerja IDSL/PUMMA berdasarkan parameter-parameter penting untuk peringatan dini tsunami seperti kerapatan data, kecepatan transmisi data, kualitas gambar CCTV camera, dan kemampuan memberikan peringatan dini itu sendiri. Data selama 9 bulan pertama berhasil dianalisa berdasarkan parameter-parameter tersebut diperkuat dengan pemodelan tsunami di Selatan Jawa menggunakan model numrik COMCOT. Hasil analisa memperlihatkan bahwa IDSL/PUMMA bekerja dengan baik dengan memberikan data valid dengan kerapatan setiap 10 detik sebanyak lebih dari 91% dengan kecepatan transmisi data di bawah 25 detik (99%). Sementara itu, gambar CCTV camera dengan kualitas baik dan sedang mencapai 69%. Berdasarkan hasil pemodelan tsunami, deteksi langsung anomali muka air tidak dapat dilakukan kurang dari 5 menit. Namun, peringatan dini tsunami berpotensi dikeluarkan melalui guncangan atau pergerakan anjungan stasiun pasang surut yang diakibatkan oleh gempabumi. Berdasarkan hasil analisa kinerja secara keseluruhan,  IDSL/PUMMA dan sistem sejenis lainnya sangat layak untuk dijadikan penguat sistem peringatan dini tsunami di Indonesia.

Ekosistem lamun merupakan salah satu ekosistem pesisir karbon biru, yang mampu memanfaatkan CO2 dan menyimpan dalam bentuk karbon organik dalam biomassa dan sedimen yang dipengaruhi oleh lingkungan. Penelitian ini dilakukan pada bulan Maret dan Oktober 2014 di perairan pulau-pulau kecil Kepulauan Seribu, DKI Jakarta. Tujuan penelitian ini mendapatkan stok karbon pada ekosistem lamun berdasarkan perubahan lingkungan, serta pengaruhnya terhadap perubahan iklim. Metode penelitian menggunakan teknik pengambilan sampel dengan cara disengaja mewakili seluruh lokasi penelitian yang terbagi menjadi tiga zona lokasi berdasarkan pengaruh lingkungannya, kemudian  menganalisis besarnya kandungan karbon dalam biomassa dan sedimen dari tiap zona lingkungan. Hasil penelitian menunjukan lamun jenis Enhalus acoroides di Pulau Burung (Zona A) memiliki nilai karbon tertinggi dari tujuh spesies lamun yang ditemukan dengan 2,58 MgC/ha, sedangkan total biomassa lamun tertinggi adalah di Pulau Panggang (Zona B) sebesar 4,39 MgC/ha dan terendah di Pulau Kotok Besar (Zona C) dengan 0,56 MgC/ha. Nilai rata-rata biomassa karbon lamun sebesar 1,81±0,32 Mg C/ha dengan komposisi terbesar di bagian bawah permukaan sebesar 75 % dari total karbon biomassa. Total stok karbon dalam sedimen ekosistem lamun berkisar antara 751,2 – 1490,4 MgC/ha sampai kedalaman satu meter. Pengaruh lingkungan berdasarkan zona lokasinya menunjukkan bahwa besaran nilai stok karbon semakin tinggi mengarah ke daratan, dengan jumlah jenis lamun yang lebih sedikit dibandingkan dengan zona yang jauh dari pengaruh daratan.Kata Kunci : Lamun, pulau-pulau kecil Kepulauan Seribu, karbon biru, lingkungan
