Abstract

Canine monocytic ehrlichiosis is a potentially fatal disease in dogs and requires an early diagnosis to start therapy properly so that it produces a good prognosis. The research was conducted to determine ehrlichiosis in Yogyakarta based on clinical, hematological, and molecular diagnoses using the gltA gene. A total of 51 dog patients who were suspected of ehrlichiosis were performed anamnesis, clinical examination, then blood samples were taken for molecular examination with PCR. The molecular examination results of dog patients who were positive for ehrlichiosis based on PCR were 33.3% (17/51), with clinical symptoms which were 58.8% weak (10/17), 47% anorexia (8/17), 47% (8/17) gastrointestinal disorders (diarrhea and vomiting), 41.1% (7/17) pale mucosa, 35.2% (6/17) tick infestation, 35.2% (6/17) fever, 29,4% (5/17) dehydration, 11.7% (2/17) bleeding. The conclusion of this study is that the clinical of patients with erhlichiosis are very varied.

Abstract

Spatial inequality occurs because the rate of availability of geospatial data has not been able to catch up and meet user needs. The root of the problem occurs because the network nodes in the area have not yet been formed or dissolved. The institutional status of network nodes at the provincial level as of October 2018, only 20 out of 34 provinces are operational, with 4 institutional options, namely UPT, Bappeda, Ad Hoc Regional Secretary and Ad Hoc Diskominfotik. This triggered anxiety for 14 regions that had not yet formed network nodes and 3 other UPTDs that were still awaiting evaluation results. To determine the institution of ideal geospatial information, BIG has conducted a study of institutional arrangements to realize effective and efficient regional apparatus organizations according to their duties and functions. The study with qualitative research methods was carried out by analyzing criteria and rating on institutional aspects in order to strengthen IDSN, based on applicable policies and laws as well as the results of the network node operationalization questionnaire in the province. Furthermore, the study was strengthened using quantitative research methods by comparing the costs and benefits of each institutional option (cost and benefit analysis) through the net present value approach. The results of the two methods are 2 alternative institutional geospatial information with the best value, namely Option 1 UPTB (Ideal for the long term) and Option 3 Ad Hoc in Regional Secretary (Quick Win for the medium term).

Abstract

Composite propellants are the primary fuel in rocket propulsion systems, consisting of a binder, fuel, and oxidizer. Ammonium perchlorate (AP) has long been used as an oxidizer in composite propellants due to its high performance and optimal combustion characteristics. However, the use of AP has negative environmental impacts due to hydrogen chloride (HCl) emissions, which contribute to air pollution and the potential for acid rain. Therefore, environmentally friendly alternative oxidizers are needed to support the defense industry. This study employs a qualitative method based on a literature review to analyze alternative oxidizers such as ammonium nitrate (AN), ammonium dinitramide (ADN), hydrazinium nitroformate (HNF), and hexaazaisowurtzitane (HNIW). The findings indicate that ADN is the most promising alternative to AP due to its good oxygen balance, high specific impulse (Isp), and more environmentally friendly combustion products. Meanwhile, HNF and HNIW exhibit high performance but are less stable and more sensitive to shocks. AN is a more economical and readily available oxidizer; however, it has limitations in terms of thermal stability and burn rate. These alternative oxidizers have the potential to replace AP in reducing environmental impact while supporting the self-sufficiency of the defense industry, considering aspects of safety, energy efficiency, and environmental impact. Further research is needed to enhance the stability of ADN and develop more efficient and sustainable production strategies for alternative oxidizers.
