Abstract

This research was conducted to design and create a model of a vortex tube refrigeration system monitoring tool that will be used as a practicum medium in the Refrigeration and Air Conditioning Engineering course. Currently, the cooling system used as a practical medium is a vapor compression cooling system. The goal to be achieved in this research is a model of a monitoring tool for vortex tube refrigeration techniques. With this monitoring model, it is hoped that it can be used to carry out practical work on vortex tube refrigeration techniques. The stages of this research start from the design stage, assembly stage and functional testing and data acquisition stages. With research flow; preparation of tools and materials, making monitoring models of vortex tube refrigeration engineering tools, testing tool models, collecting and processing data from model experiments. This monitoring tool model for Vortex Tube Refrigeration can directly monitor things such as; Flow rate, temperature, air pressure and COP, all data is recorded and stored on the SD card. The higher the pressure, the cooler the cold air produced, this is because the vortex tube compresses the air. The highest COP value is 0.31 which occurs at the standard 3 bar setting with v1 and v2 (72 and 61 m3/s), P1 and P2 (1.8 and 0.28 bar).

Abstract

Menurut Badan Pusat Statistik Kabupaten Kubu Raya yang dituangkan dalam Statistik Pertanian Tanaman Pangan Tahun 2015, area ladang sawah memiliki luas total 52.679 Ha di tahun 2015 yang tersebar di sembilan kecamatan. Salah satunya terdapat di Desa Teluk Nibung, Kecamatan Batu Ampar Luas lahan 25 ha dengan kapasitas produksi 40-50 ton/ tahun dalam satu kali produksi. Selama ini kegiatan Kelompok Tani Nibung Mandiri 2 masih terlalu konvensional, sehingga produksi padi yang dihasilkan pun masih tergolong sedikit. Itu dikernakan masih belum terjangkaunya peralatan pendukung untuk pengolahan dan proses pasca panen di Kelompok Tani Nibung Mandiri 2. Dengan adanya alat bantu untuk proses awal penanaman sampai dengan pasca panen tentunya memberikan harapan bagi Kelompok Tani Nibung Mandiri 2 untuk dapat mempersingkat waktu penanaman padi sehingga dapat meningkatkan produktifitas pada Kelompok Tani Nibung Mandiri 2. Penerapan Ipteks pada “Kelompok Tani Nibung Mandiri 2” ini adalah dengan memberikan bantuan berupa alat traktor dan mesin tebas untuk dapat mempersingkat waktu penanaman padi sehingga dapat meningkatkan produktifitas pada Kelompok Tani Nibung Mandiri 2.

Abstract

Gingivitis is a periodontal disease that is often found in the oral cavity. According to Health Research in 2018, the prevalence of gingivitis in Indonesia is ranked second which shows a figure of 96.58%.  The causes of gingivitis are grouped into local factors and systemic factors. Local factors include caries, failed restorations, and piles of food waste, while systemic factors include nutritional, hormonal, and hematology. An abnormal hematological condition that can cause gingivitis is increased polymorphonuclear leukocyte levels in the blood circulation. Polymorphonuclear leukocyte levels can be affected by a person's sleep quality, poor sleep quality can trigger an increase in leukocyte levels. Poor sleep quality is vulnerable to being experienced by shift workers, including the security unit (security guard). This study aims to determine the correlation between polymorphonuclear leukocyte levels and gingivitis in the Universitas Muhammadiyah Surakarta (UMS) security unit. This study uses an observational type of analysis with a cross-sectional approach. The sampling technique uses non-probability sampling in the form of purposive sampling. The sample used was 30 UMS security guards. The data were analyzed using the Chi-Square non-parametric statistical test. The data of this study was obtained from the results of an examination of polymorphonuclear leukocyte levels and gingivitis examination in the form of a gingival index of respondents conducted at RSGM Soelastri Surakarta. The instruments used are diagnostic sets and hematology analyzers. The results of this analysis test obtained a significant value with a value of p=0.035. Conclusion of this study There is a relationship between

Abstract

Background: Gingival enlargement is a pathological condition characterized by excessive growth of the gingiva. Objective: To describe a case of gingival enlargement treated with a gingivectomy procedure. Case report: A 67-year-old woman came to Soelastri General Hospital complaining of enlarged gums. The complaint had been felt for 1 month. The patient complained that her upper right gum was enlarged and often bled. Intraoral examination found gingival enlargement in region 12. The treatment plan was scaling and root planing followed by gingivectomy. Discussion: Gingival enlargement in this patient was treated with phase 1 periodontal therapy, followed by gingivectomy. Gingivectomy improves visibility and accessibility to remove superficial deposits and thoroughly smooth the roots, creating a good environment for healing and restoration of the physiological contour of the gingiva. Conclusion: Gingivectomy is a procedure to eliminate gingival enlargement and requires periodic supportive periodontal therapy to monitor for recurrence in the future.

Abstract

Chronic periodontitis is defined as an inflammatory condition of the periodontal tissues caused by specific subgingival microorganisms, resulting in the progressive destruction of the periodontal ligament and supporting tissues of the teeth. The primary clinical characteristic of chronic periodontitis is detectable clinical attachment loss, often accompanied by periodontal pocket formation and changes in the density and height of the alveolar bone. This condition may lead to pathological tooth migration, resulting in diastema formation and increased tooth mobility, which can ultimately cause tooth loss. Increased tooth mobility may negatively affect masticatory function, aesthetics, and patient comfort. One of the treatment modalities used to stabilize mobile teeth is splinting. Splinting combined with occlusal adjustment is intended to reduce and control the progression of tooth mobility. Case Report: A 54-year-old female patient presented to Soelastri Dental Hospital with a chief complaint of mobility of the lower anterior teeth that had been present for approximately six months. The patient reported that the teeth felt loose during mastication, particularly when contacting the maxillary teeth. Intraoral examination revealed Grade 2 tooth mobility in teeth 32, 31, 41, and 42. Bleeding on probing was observed in the mandibular anterior region. Periodontal pocket depths around teeth 32, 31, 41, and 42 ranged from 5 to 6 mm. Radiographic examination demonstrated alveolar bone loss associated with these teeth. Management of this case involved the placement of a fiber-reinforced composite splint extending from teeth 33 to 43. Fiber splinting was selected because of its advantages, including high mechanical strength, excellent adhesive properties, biocompatibility, satisfactory esthetics, and ease of clinical application. Evaluation one week after splint placement showed favorable outcomes, with no signs of gingival inflammation or food impaction in the splinted area, as well as satisfactory occlusal relationships.
