Fibromatous epulis is a hyperplastic reaction of fibrous connective tissue due to chronic stimulation or irritation, such as calculus or sharp parts of the retained root. The mass was pedunculated, pale pink in color, solid consistency, the boundary was firm, and was not easy to bleed with no pain. Objective : Discuss the management of fibromatous epulis by excision Case :A 25-year-old male patient who suffered from unusual unilateral, gingival enlargement in lingual anterior mandible. The masses appeared since a year ago, initially small and gradually grew to the size 3 cm, solid consistency, well-defined, not easy to bleed, and not painful. The patient was diagnosed with fibromatous epulis and chronic periodontitis based on the clinical, histological, and radiographic findings. The mass has been treated by excision. Case Management :The gingival enlargement was treated by conventional gingivectomy under local anaesthesia.The postoperative result was uneventful. Conclusion : The excision of fibromatous epulis was carried out to remove the mass and eliminating the predisposed factor. 2022-09-04T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1333 THE USE OF ELECTRO SURGERY FOR EXCISION THE GINGIVAL TUMOR: Case Report Rizka, Yoifah; Nilawati, Nina Introduction: The gingiva tumor often called epulis, caused by uncontrolled growth due to excessive or continuous stimulation of the gingiva. Epulis treatment is to remove the tumor by means of either excision with a scalpel, laser or electro surgery. Objective:This case report aims to provide information the use of electro surgery for excision the gingival tumor. Case 1: A25-years-old woman, present with tumor in the lower jaw gum. Tumor arise since 1 year ago, not pain but interfere. The surface of tumor shiny, reddish, clear boundaries, dense chewy and fixed.Case 2:A 46-yeas-old female patient with tumor diameter of 3mm on the gum region 16. Tumor arise since 3 year ago with the longer growing.The surface of the tumor, shiny, pale, no pain and no bleed easily. In both patients do not obtain systemic abnormalities and there is no alveolar bone loss in radiographic examination. Case Management:Excision of the tumor with electro surgery, after examination with Fine Needle Aspiration (FNA) biopsy showed no sign of malignancy. Conclusion: The use of electro surgery for excision the gingival tumor does not cause bleeding and no need periodontal pack, but the healing longer than excision with a scalpel.

One of the bacteria that causing this disease is Porphyromonas gingivalis (P.g). Handling periodontitis with Diabetes Mellitus does not include local factors only, but also systemic factors such as handling of blood sugar because therapy of periodontitis in patients with systemic disease also has the potential to improve overall general conditions. Mechanical periodontitis teraphy can be carried out by scaling and root planing (SRP) but the healing it does not indicate the new connective tissue attachment. High pressure oxygen teraphy (HBOT), teraphy with breathing using 100% oxygen in high pressure chamber (more than 1 ATA), can accelerate alveolar bone healing as part of health tissue regeneration Purpose: To prove the effects of high pressure oxygen teraphy in the increasing of alveolar bone osteocytes of rat with DM induced by P.g. Materials and Methods: This research adopts post test only control group design. Fifteen male wistar rats are divided into three groups. K- ( negative control group), K1: induced by P.g and Streptozotocin, and K2: induced by P.g, Streptozotocin, high pressure oxygen teraphy 2,4 ATA 100% O2 3x30 minutes with five minute interval of air inhalation for five consecutive days. Results: Kruskal-Wallis test (p<0,05) and Mann-Whitney U (p>0,05) shows decreasing of osteocytes of alveolar bone significantly in K1 (3,55±0,93) that compared with K0 (5,33±2,32), increasing significantly in K2 (5,40±1,51) that compared with K1 (3,55±0,93), and no main changes between K2 (5,40±1,51) and K0 (5,33±2,32). Conclusion: HBOT 2,4 ATA 100% O2 3x30’ with 5’ interval of air inhalation for five consecutive days can increase of alveolar bone osteocytes of rat with DM induced by P.g. 2017-10-05T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1225 Prosthetic Rehabilitation of a Partially Edentulous Patient with Chronic Periodontitis Nanik.K, Chaterina Diyah Background: One of the most common inflammation disease in the oral cavity for the past few years is the chronic form of periodontitis. Patients with chronic periodontitis, who her jobs requires to interact with people are a real challenge for the dentist and the prosthetis. The problem with the traditional method is the fact that for rehabilitation of patients who have lost their tooth/teeth , has to be waited for approximately 8 to 12 weeks before having their dentures. There are many advantages of immediate as opposed to conventional complete denture. Hence, dentists have no opportunity to observe the anterior teeth at the try in appointment; therefore, the esthetic result cannot be evaluated until the dentures are inserted. Purpose: The prosthetic rehabilitation of a partially edentulous patient with chronic periodontitis using immediate maxillary full denture and immediate mandibular partial overdenture. Case and Case management: We presented a patient suffered from chronic periodontitis with major complain of her teeth mobility, mostly anterior teeth. She had undergone periodontal treatment, but the result were bad. In maxilla, at the end of peridontal treatment, all of her teeth need to be extracted and replaced by dentures. In mandible, there were some teeth that can be used as abutment for an overdenture, so we decided to place immediate partial overdenture in mandible with consideration both of her functional and esthetic aspects. Conclusion: One of the advantages of immediate dentures is patients don’t have to be in edentulous state for any length of time. After treatment, patient was evaluated, fortunately she had no complaints and was happy with her new smile. 2016-08-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1202 Method for Estimating Cost of New Ship Building with Linear Regression Azhar, Ali; Kristiyono, Tri Agung The request of a fleet of marine transportation can be fulfilled by constructing new vessels and purchasing secondhand vessels. The current constraints in building new vessels are cost relatively expensive and take a long time, while the advantages for the procurement of vessels of secondhand time relatif faster and the price is cheaper. New shipbuilding includes complex work with the multy year’s payment system, so it is important to develop the cost budget needed to build a new ship. The price should be adjusted concerning material needs and services with the standard market price during the completion time of the work and expected the calculation of the construction of a ship can be updated periodically. The research aims to identify, analyse and construct the cost estimation of the construction of the ferry types: 300 GT, 500 GT, 600 GT, 750 GT and its components. The stages that will be carried out in this study are to identify primary and secondary data relating to the construction costs of ferries and their components with field surveys, market surveys, and relevant library studies. Data is processed by linear regression methods to construct an estimate of the cost of building ferries and their components. Results obtained in the form of graphs and equivalencies of the cost of building ferries and material cost components, labour costs, and shipyard and third party cost 2022-02-04T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1165 How to Manage The Mucocele on The Lower Lips Nilawati, Nina 2017-05-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1164 Tips Pemasangan Implan Gigi Bagi Pemula Nilawati, Nina 2014-01-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1162 Nicotine Effect on The Number of Osteclast and Osteoblast After Dental Implant Placement Nilawati, Nina 2013-01-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1159 THE INFLUENCE OF EYE STALK ABLATION TO GONADAL MATURITY OF MUD CRAB SCYLLA SERRATA THAT CULTIVATED ON BATTERY CELL CAGE Wijaya, Nirmalasari Idha; Triyanto The aim of the research is to know the level of Gonadal Maturity (GM) female crab with eye ablation technique. The research was executed at ponds of Semanting Village, in Derawan Island District, Berau Regency, East Kalimantan Province. The animal tests was female mud crab (Scylla serrata) genitals mature which had early body carapace width ranging 90-120 mm, undeveloped ovary (immature) but had done copulation. The experimental design utilizerandomized block design. treatment was done ablation of 100% right eye stalk (treat A), ablation of 50% right eye stalk (treat B), and without ablation (treat C), with three replications, were applied. These were grown for two weeks maintained on battery cell cage. The results of the study, showed that to reach the gonad maturity level IV or perfectly mature, the parent crab treated eye stalk ablation 100% (A) shows the percentage achieved relatively higher, reaching 66,7% compared to the parent crab treated with ablation of 50% (B) which only reached 53,3%. However, statistical tests both treatments showed no significant difference (P> 0,05). While the parent crab ablation untreated (control), indicating the percentage achievement of gonad maturity level is lower than the parent crab treated with ablation of only 23,3%. In the only treatment A statistical test that showed significant differences with the control (P <0,05), while treatment B showed no significant difference with control (P> 0,05). Other parameters observed in this research is the gonad maturation index and survival rate, which shows the result of three treatments statistically was not real different (P>0,05). The value of water quality measurements include temperature, pH, dissolved oxygen and salinity during the research is still optimal for the maintenance of mud crab. The concluded of the research was the treatment of eyestalk ablation effective accelarated gonadal mature.. 2014-01-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1156 The Effect of Seasons and Humans Behaviour to The Aedes aegypti Larvae Density in The DHF Endemic Area of Mojo Village, Surabaya Simatupang, Risma 2016-05-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1155 Density Figure's Status and Frequency Distribution Container in The Dengue Haemorrhagic Fever Endemic Area of Kedung Cowek Village, Bulak District, Surabaya Simatupang, Risma 2016-05-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1154 Intestinal Worm Infection and Anemia Among Children Aged 4-6 Years in Gisik Cemandi, Sidoarjo, Indonesia: A Public Health Concern In a Coastal Area Utami, Prawesty Diah; Diarsvitri, Wienta; Simatupang, Risma 2013-07-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1149 THE DIFFERENCES BETWEEN THE MEAN NUMBER OF AEDES AEGYPTI LARVAE IN THE DARK CONTAINER AND BRIGHT CONTAINER IN TAMBAK CEMANDI VILLAGE, SEDATI, SIDOARJO Dewi, A Mahdha Rahma; Risma Dengue Hemorrhagic Fever (DHF) is still a serious problem.

With a vast array of medical journal articles published each year, it is essential to develop a systematic approach to find and read a journal article. The systematic approach to find and read a journal article is described as the following: the reader should first enter the appropriate keywords relevant to the reader’s interest, only then the reader begin by reading the title, abstract and conclusions first. If a decision is made to read the whole article, the key sections of the article can be appraised in a systematic manner effectively and efficiently. That systematic manner was elaborated in this paper. The reader should be able to read and appraise a journal article if a systematic approach is used in a simple and rational manner. The reader should hone this particular reading skill by familiarizing oneself to read every scientific manuscript using this systematic approach. Keywords : Journal Articles, Reading, Systematic Approach, Title, Abstract, Conclusion. 2018-01-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1112 Supply chain performance analysis on modular construction shipbuilding Baroroh, Intan; Ariana, I.M.; Dinariyana, A.A.B.

The Implementation of modular construction shipbuilding aims to accelerate ship production so that delivery time can be shortened. However, in its implementation, delay for completing and delivery the ship can still be found. The delay in delivery is influenced by the supply chain performance of the shipyard due to delays in design, material, and financial payments. This delay occurred due to the large number of sub-module and module construction works carried out in parallel. The works include hull construction, painting, outfitting and installation of equipments.This study aims to analyze the performance of the supply chain in shipyard that implementing modular construction system. In the initial stage, the study is conducted by defining the factors and parameters that affect supply chain performance in shipbuilding and determining factors that have the potential to cause delivery delays. The conceptual and technical approach is carried out by analyzing the causal relationship of the factors that have identified in the previous stage. Dominant factors that cause delays that occur in ship building are expected to find and observe using system dynamics approach.Keywords: Supply chain performance, Modular construction, System dynamic. 2020-01-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1111 The Fortication of Iodine in Salt Consumption Using Manual Gun Spray Baroroh, Intan; Suwasono, Bagiyo; Hardianto, Didik The Blue Economy concept begins with Artemia salt farming. The salt farming industry is one of the pillars supporting the economic of coastal community. However, in the market, most of salt consumed have iodine level that is less than 30 ppm. Therefore, it is necessary to measure the supply of iodized salt from the market to reach 30 - 80 ppm iodium according to Indonesia National Standard because it can impact our health. Thus, it was necessary to repair the iodized salt production equipment through an iodine spray device on the machine. The result of spray setting modification technology on macro ranged from 38 - 45 ppm which fulfilled Indonesia National Standard 2018-01-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1110 The Combination Process between Disc-Mill and Distillation Evaporation in Producing Salt Diversification Products Baroroh, Intan; Suwasono, Bagiyo; Munazid, Ali Abstract. Blue Economy concept began with the farming of Artemia salt. The industry of farmer’s salt was one of the pillars that supported the economy of coastal communities. At present, the perspectives of the public on an industrial salt production is less profitable and conducted by unskilled laborers. Nowadays, the farmer still use the evaporation total method of sea water by solar power, where the NaCl was ≤ 90% and residual brine. It is necessary to improve the salt production through combination between disc-mill and distillation evaporation technology to produce salt diversification product. The result of the combination process were refined salt with NaCl that was ≥ 90%, liquid salt with NaCl that was ± 60% and mineral water. 2017-01-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1109 Method for Estimating Price of Second hand Ship with Multi Method Azhar, Ali Demand fleet as a means of marine transport could be met by building new ships and buying second-hand vessels.

Recent attention has been focused on our understanding of the negative influences of oral chronic inflammation on systemic health. There is growing evidence that periodontal diseases may affect general health. Periodontal diseases have powerful and multiple influences on the occurence and severity of systemic conditions and disesases, such a diabetes mellitus, cardiovascular diseases, respiratory diseases, and pregnancy complications. The relationship of periodontitis and diabetes has been supported by sufficent evidences in the past twenty years and has long been discussed with conflicting conclusions. Both'of these diseases have a relatively high incidence globally in the general population with a number of common pathways in their pathogenesis. Their relationship appears bi-directional insofar that the presence of one condition tends to promote the other, and that the appropriate management of either may assist treatment of the other. However, the converse possibility that periodontal disease either predisposes or exacerbates the diabetic condition has received little attention, and it is only less known about the impact of periodontal diseases on the diabetes-related inflammatory state. Although type 2 diabetes is a multiple risk-factor syndrome, lowered insulin sensitivity, called insulin resistance, is essential in developing the disease. Proinflammatory cytokine produced from chronic inflammation subjects as periodontitis, is known to playa predominant rolein inducinginsulinresistance. ' This review attempts to explain the immunobiological connection between periodontal disease and diabetes mellitus type 2, exploring the mechanisms through which periodontal infection can contribute to the low-grade general inflammation associated with diabetes (thus worsening insulin resistance) and discussing the impact of periodontal treatment on glycemic control in people livingwith both diabetes and periodontal disease. 2012-03-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1106 Host Modulatory Therapy in Aggressive Periodontitis Widyastuti, Widyastuti Abstract Host modulatory therapy (HMTs) ia a treatment concept that goal to reduce tissue destruction and stabilize or even regenerate the periodontium. The aggressive periodontitis result in rapid destruction of the periodontium and can lead to early bone destruction, until tooth loss. HMTs modifying or downregulating dectructive aspects and upregulating protective aspectc of the host response, in combination with conventional treatments to reduce the bacterial burden, the balance between health and disease progression is tipped in the direction of a healing response. Many aspects of the host response can be affected, including modification of proteolytic enzymes such as matrix metalloproteinases, stimulation of cellular activity, and alteration of the extracellular matrix, all these aspects can be considered as host modulation. HMTs are systemically or locally delivered pharmacheuticals that are prescribed as part of periodontal therapy and are used as adjuncts to conventional periodontal treatments. A variety of different drug classes have been evaluated as host modulation agents, including the nonsteroidal antiinflammatory drugs (NSAIDs), biphosphonates, chemically modified tetracyclines (CMTs) or subantimicrobial-dose doxycycline (SDD). The concept of periodontal medicine is not only the bacterial challenge by scaling and rootplaning (SRP) but also the host side of the host-bacterial interactions. Subantimicrobial-dose doxycycline (SDD) is the only HMTs currently approved and indicated as an adjunct to SRP for treating aggressive periodontitis. 2012-03-01T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1105 Effect of Avicennia marina sp leaf extract to rat gingival catalase level induced by mix periodontopathogen bacteria Widyastuti, Widyastuti ABSTRACT Background : Periodontal disease is the second largest oral disease in Indonesia population caused by infection of periodontopathogen bacteria. Most of the bacteria of periodontitis are Gram negative anaerobic bacteria. Avicennia marina sp is a natural product that has some medical potential regarding to its nutritional contents including antioxidant activity. Objectives : The aim of this study is to investigate the effect of Avicennia marina sp extract on catalase activities in gingival Wistar rats induced mix periodontopathogen bacteria.

Rhizophora mucronata bark extracts have been found in previous studies to exhibit antibacterial activity. Objectives: This study aims to determine the cytotoxicity of Rhizophora mucronata bark extracts as an intracanal medicament. Method: Gingival mesenchymal stem cells (GMSCs) were exposed to the Rhizophora mucronata bark extracts at different concentrations of 0.5% (Group 1), 1% (Group 2), 2.5% (Group 3), 5% (Group 4), 10% (Group 5), and 20% (Group 6) to assess its cytotoxic effect. In addition, there were two control groups; one containing only the culture medium while another only with the cells. Cell viability was assessed by 3-(4, 5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. This was done by adding MTT solution into each well after 3 minutes and then incubating them for 4 hours. Dimethylsulfoxide (DMSO) was then added to each well and shaken to mix. The absorbance was then measured on an ELISA plate reader with a reference wavelength of 630 nm. The extract at that said concentration is identified to be non-toxic if the cell viability is ≥ 50 %. Results: There was significant difference in cell viability of the GMSCs at various concentrations of the extract. The highest cell viability was found in group of cells which was treated with 1% concentration of Rhizopora Mucronata extract, while the with 10% concentration Rhizopora Mucronata significantly reduced the cell viability to the lowest among all groups. Conclusion: Rhizophora mucronata bark extracts at concentrations of 0.5%, 1%, 2.5%, and 5% can be used safely as endodontic intracanal medicament. 2017-08-10T00:00:00Z http://dspace.hangtuah.ac.id:8080/xmlui/handle/dx/1096 Cytoxicity Test of Diadema Setosum Shell Extract Againts Fibroblast Culture Cell Irawati, Novi Virina; Aprilia, Aprilia; Ashrin, Meinar Nur Background: Calcium is one of the basic ingredients of calcium hydroxide which is used in the field of dentistry as pulp capping material.
