Telah dilakukan uji laboratorium dan uji lapangan dalam skala kecil dengan vetrazin (OMS—2014) terhadap larva Culex quinquefasciatus dan larva Aedes aegypti di Jakarta. Hasil uji laboratorium menunjukkan bahwa larva Cx. quinquefasciatus lebih rentan terhadap OMS—2014 dibanding dengan larva Ae. aegypti. LC50 untuk larva Cx. quinquefasciatus adalah 0,13 mg/l, sedangkan untuk larva Ae. aegypti adalah 0,48 mg/l. Uji labo ratorium menunjukkan pula bahwa beberapa larva dapat menjadi pupa, tetapi kebanyakan mati dalam bentuk pupa. Di samping itu terdapat pengaruh terhadap terjadinya pupa, sehingga kematian yang terbanyak terjadi pada stadium larva. Hasil uji lapangan menun jukkan bahwa OMS—2014 lebih efektif terhadap larva Ae. aegypti daripada larva Cx. quinquefasciatus. Hasil uji lapangan dalam skala kecil dengan OMS— 2014 terhadap larva Ae. aegypti efektivitasnya sama dengan hasil uji dengan methoprene dan sedikit lebih pendek daripada diflubenzuron. Untuk memberantas larva Cx. quinquefasciatus dalam selokan yang airnya tercemar, efektivitasnya sama seperti dengan methoprene dan diflubenzuron
School Strategies to Utilize the Ecotourism Potency of Songgoriti and Cangar of Batu City Tourisms as Learning Sources in High School
School strategies and perceptions of the school principals in utilizing the ecotourism potency is one of important things-which is used as an effort to support the improvement of the quality of learning, not much has been revealed yet. This study aimed at analyzing the school strategies and perspective of school principal in utilizing the ecotourism potency of Songgoroti and Cangar-Batu City tourisms as learning sources in High School. This study used a qualitative approach. Phenomenology was used as design of study. Teachers, school principals, and students of SMAN 3 Malang, SMA Sholahuddin Malang, and MAN 1 Malang were the informants of study. Sampling technique used was purposive sampling. Data collection methods used in this study were in-depth interview and questionnaires. The data of study obtained were analyzed by means of content analysis referred to Interactive Models Miles, Huberman and Saldana, and those were presented in a descriptive description. The results of study indicated that the school strategies in utilizing the ecotourism potency covered up 1) the analysis strategy of ecotourism potency as effective learning sources for High School in an effort to determine learning place, Â in which it consisted of two strategies, namely (a) Student- Teacher Centered Strategy and (b) Teacher -Student Centered Strategy; 2) The planning strategy in utilizing the ecotourism potency as effective learning sources consisted of three strategies, namely (a) initiator strategy, (b) planning policy-making process strategy, and (c) planning implementation strategy; and 3) The implementation strategy in utilizing the ecotourism potency consisted of two strategies, namely (a) Collaborative/Resource sharing Strategy, dan (b) Semi-collaborative Strategy. The perceptions of school principals in utilizing the ecotourism potency were that the school principals were very supportive, both through direct statements and through policies made. It can be concluded that there are various strategies to utilize the ecotourism potency of learning sources in High School. The principals reinforce the utilization effort through direct statements and policies that are made. In the future, a study is needed on the implementation of the utilization of ecotourism potency in learning
Determination of Meat Content in Processed Meats Using Currently Available Methods
Four methods were used in the determination of meat content in local meat and meat products. Current methods
available are not reliable and applicable to routine monitoring and quality control by the regulating laboratories as well as the meat processing industry. A reliable and practical method is needed to monitor meat Introductions and ensure that they are meeting the minimum requirement of sixty five (65 %) percent meat content. The
total pigments and hemoglobin technique was found to be applicable for determination of meat content in
locally Inocessed beef burgers, when compared to the Modified Method of Stubbs & More (1919), and Pearson
Method (1975
Causes and Outcomes of Spontaneous Pneumothoraces in Solid Tumor Cancer Patients: An Update for the Medical Oncologist
PurposeDefined as lung collapse in the absence of a recent invasive thoracic procedure, a spontaneous pneumothorax can be a catastrophic event, leading to abrupt shortness of breath, chest pain, hypotension, and occasionally death. A dearth of present day information on this entity in solid tumor cancer patients prompted this single-institution retrospective study on current causes and outcomes.MethodsAll patients with diagnoses of “spontaneous pneumothorax” and “cancer” between 1990 and 2004 had their records retrieved and reviewed. Among 546 patients with a diagnosis of spontaneous pneumothorax, only 25 (5%) met predefined inclusion criteria that included an antecedent diagnosis of an invasive solid tumor malignancy. Lung (n = 5) and bladder cancer (n = 4) were the most common malignancies; eight patients had received radiation and one had received carmustine. Of note, 78% were smokers, 13 had chronic obstructive pulmonary disease, and 12 had no known active cancer at the time of the pneumothorax.ResultsPneumothorax management was associated with great morbidity, including hospitalization in 24 patients and chest tube placement and/or surgery in most patients. Median survival for the group as a whole was 31 months, but patients with known active cancer tended to do poorly, with only a 3-month median survival.ConclusionA spontaneous pneumothorax is rare, and patients with known active cancer tend to do poorly. However, even patients with no known active cancer are at risk, perhaps in part from smoking. The fact that patients with no known active cancer can live for years after this event suggests that the pneumothorax should not be assumed to be related to cancer recurrence, that cancer restaging is not always mandatory, and that there is justification for managing the pneumothorax in this subgroup aggressively
Uses of cetyl cacaoateTM in lipstick development: sensory evaluation
The use of Cetyl CacaoateTM in lipstick formulation was evaluated by varying the porpotion of waxes mixture among carnauba wax, jojoba ester and Cetyl CacaoateTM based on Simplex centroid {3,3} experimental design. Sensory evaluation was carried out by nine trained panels using quantitative descriptive analysis (QDA) method. The attributes agreed in the sensory languages development session were easy to apply, off flavor, hardness, texture, moist, appearance on lip after use, glossy, oily, comfortability after use, and long lasting. Results showed that Cetyl CacaoateTM increased the score of easy to apply but decreased the score for hardness. Cetyl CacaoateTM in the lipstick formulation increased the oily feels whereas carnauba wax gave less oily effect. No off flavor was detected for all the samples. However, the panels had different perception on comfortability after use, and long lasting. The ratio of cosmetic waxes in lipstick formulation which gave scores close to reference sample were 1/2 Cetyl CacaoateTM : 1/2 jojoba ester and 2/3 Cetyl CacaoateTM : 1/6 jojoba ester : 1/6 lilin carnauba
