PENENTUAN PENGARUH KULIT ARI PSYLLIUM DAN SUSU FULL CREAM TERHADAP KADAR AIR DAN ABU PADA PEMBUATAN CREAM CHEESE MENGGUNAKAN RESPONSE SURFACE METHODOLOGY

Cream cheese adalah salah satu jenis keju yang kaya akan nutrisi dan dibuat dengan metode koagulasi asam, termasuk menggunakan fermentasi dengan bakteri asam laktat. Cream cheese memiliki tekstur yang lembut, halus, putih dan creamy serta memiliki cita rasa asam. Untuk meningkatkan kualitas cream cheese dapat ditambah dengan kulit ari psyllium (Platago ovata) dan susu full cream yang masing-masing dapat berperan sebagai stabilizer dan memperbaiki cita rasa. Penelitian ini  betujuan untuk menentukan pengaruh kulit ari psyllium dan susu full cream terhadap kandungan air dan abu produk cream cheese. Fermentasi susu dilakukan dengan menggunakan Lactobacillus bulgaricus dengan variasi penambahan kulit ari psyllium (0.1-0.5%) dan susu full cream (8-16%). Percobaan dilakukan dengan menggunakan response surface method-central composite design. Hasil eksperimen menunjukkan bahwa kulit ari psyllium memberikan efek yang signifikan terhadap kandungan air (p = 0,035) dan abu (p = 0.009) produk cream cheese. Persamaan yang diperoleh pada eksperimen ini dapat digunakan untuk mengatur kandungan air dan abu produk cream cheese yang dibuat

Studi Pengaruh Kulit Ari Psyllium dan Susu Full Cream Terhadap Kandungan Laktosa, Asam Laktat dan pH Cheese Cream Menggunakan Response Surface Method

Cream cheese merupakan keju yang lunak bertekstur creamy yang diproduksi melalui koagulasi cream atau campuran susu dan cream dengan kultur bakteri asam laktat (BAL). Penambahan BAL ke dalam susu akan menggumpalkan protein berupa kasein karena terjadi fermentasi laktosa menjadi asam laktat sehingga susu menjadi asam dan kasein terkoagulasi. Penggumpalan kasein akibat fermentasi oleh BAL akan mempengaruhi viskositas dan tekstur yang menjadi kriteria dalam penentuan mutu pangan. Bahan penstabil perlu ditambahkan untuk menjaga sifat viskositas, konsistensi fisik, dan stabilitas produk. Kulit ari psyllium (Plantago ovata) mengandung hemiselulosa yang memiliki kapasitas menahan air hingga kira-kira 80 kali beratnya. Penambahan susu full cream dapat digunakan untuk meningkatkan rasa dan juga tekstur yang lebih padat pada produknya. Tujuan penelitian ini yaitu menganalisis pemanfaatan kulit ari psyllium dan susu full cream dalam pembuatan cream cheese yang dioptimisasi dengan rancangan Response Surface Method (RSM) menggunakan desain Central Composite Design (CCD) untuk menghasilkan respon kadar laktosa, kadar asam laktat, dan nilai pH optimum. Metode yang digunakan yaitu pembuatan cream cheese yang dilakukan dengan penambahan starter Lactobacillus bulrgaricus kulit ari psyllium dan susu full cream sesuai rancangan RSM-CCD, penentuan kadar laktosa dengan metode ferrisianida basa, penentuan asam laktat dengan metode titrasi dan pengukuran nilai pH cream cheese dengan pHmeter. Hasil analisis menunjukkan bahwa kadar laktosa minimum agar laktosa yang digunakan sebagai substrat untuk pembentukan asam laktat lebih banyak maka penggunaan konsentrasi susu full cream 17,66% dan kulit ari psyllium 0,09% dengan kadar laktosa 0,82%; untuk menghasilkan kadar asam laktat maksimum maka penggunaan konsentrasi susu full cream 9,20% dan kulit ari psyllium 0,58% dengan kadar asam laktat 2,47%; sedangkan untuk dapat menghasilkan pH optimum penggumpalan kasein, maka dapat dilakukan penggunaan konsentrasi susu full cream sebesar 6,34% dan kulit ari psyllium sebesar 0,02%

Need for recovery amongst emergency physicians in the UK and Ireland: A cross-sectional survey

OBJECTIVES: To determine the need for recovery (NFR) among emergency physicians and to identify demographic and occupational characteristics associated with higher NFR scores. DESIGN: Cross-sectional electronic survey. SETTING: Emergency departments (EDs) (n=112) in the UK and Ireland. PARTICIPANTS: Emergency physicians, defined as any registered physician working principally within the ED, responding between June and July 2019. MAIN OUTCOME MEASURE: NFR Scale, an 11-item self-administered questionnaire that assesses how work demands affect intershift recovery. RESULTS: The median NFR Score for all 4247 eligible, consented participants with a valid NFR Score was 70.0 (95% CI: 65.5 to 74.5), with an IQR of 45.5-90.0. A linear regression model indicated statistically significant associations between gender, health conditions, type of ED, clinical grade, access to annual and study leave, and time spent working out-of-hours. Groups including male physicians, consultants, general practitioners (GPs) within the ED, those working in paediatric EDs and those with no long-term health condition or disability had a lower NFR Score. After adjusting for these characteristics, the NFR Score increased by 3.7 (95% CI: 0.3 to 7.1) and 6.43 (95% CI: 2.0 to 10.8) for those with difficulty accessing annual and study leave, respectively. Increased percentage of out-of-hours work increased NFR Score almost linearly: 26%-50% out-of-hours work=5.7 (95% CI: 3.1 to 8.4); 51%-75% out-of-hours work=10.3 (95% CI: 7.6 to 13.0); 76%-100% out-of-hours work=14.5 (95% CI: 11.0 to 17.9). CONCLUSION: Higher NFR scores were observed among emergency physicians than reported in any other profession or population to date. While out-of-hours working is unavoidable, the linear relationship observed suggests that any reduction may result in NFR improvement. Evidence-based strategies to improve well-being such as proportional out-of-hours working and improved access to annual and study leave should be carefully considered and implemented where feasible

Optimizing Visually Impaired Ability to Read Tactile Pictogram Through Texture Design

. This experiment aims to optimize the visually impaired ability when reading tactile pictograms through texture design. Experiment was motivated by two previous studies results by authors show that the visually impaired need a tool to make the reading process more efficient. Overall, the visual semiotic was used to adapt the Space-Time-Curve (STC), Tabrani's visual language theory, as a texture media design system. The design result produces media textures with size composition differences. The media was tested on 20 visually impaired people directly with quantitative analysis technique. The results show that the design system for media textures is not able to optimize visually impaired reading. In general, it concluded that the visually impaired do not perceive a system without memory regarding its variable mechanism as a whole

Extensive subcutaneous emphysema following lobectomy

We present a case report of extensive subcutaneous emphysema secondary to an elective left upper lobectomy. A 65-year-old gentleman was brought into a London teaching hospital’s Accident and Emergency department following report of severe swelling. He was mistakenly treated by the paramedics as an allergic reaction and given hydrocortisone and salbutamol nebulisers with no effect. Upon arrival, the patient had widespread crepitus extending from his peri-orbital muscles down to mid-torso. A computer tomography scan revealed a pleuro-cutaneous fistula at the site of a recently sited chest drain, with extensive emphysema and a pneumothorax. A Seldinger chest drain was successfully inserted under blind technique following two attempts. This case highlights the risk of subcutaneous emphysema following thoracic surgery, the importance of correct diagnosis and the difficulties of left-sided intercostal drains in patients with subcutaneous emphysema

Fitz-Hugh–Curtis syndrome - a diagnostic challenge

Diagnosis of Fitz-Hugh-Curtis is challenging due to its rarity and its similar presentation to common intra-abdominal conditions, such as cholecystitis or appendicitis. In our case the adherent caecal and omental mass felt on examination was thought to be an appendiceal mass secondary to perfo- ration, hence the patient underwent a diagnostic laparoscopy

Blood patch for the treatment of post-dural puncture tinnitus

Audiometric disturbances are recognised as potential complications after spinal or epidural anaesthesia; however, incidences of tinnitus occur less frequently. We report a case of a patient with severe bilateral tinnitus post-lumbar puncture who was treated with an epidural blood patch. A 40-year-old ASA I lady (a medically fit patient with no known medical problem) presented with ongoing bilateral severe tinnitus for 6 days after a lumbar puncture. Venous blood (18 mL) was injected into the epidural space using a 16G needle. The patient completed the Tinnitus Handicap Inventory Questionnaire before the blood patch, 3 h, 24 h and 1-month post-procedure. An audiogram was also conducted before and 1 month after the blood patch. The patient scored 84 (grade 5) on the Tinnitus Handicap Inventory before the blood patch. Three hours post-procedure, her score improved to 16 (grade 1), with complete resolution by 24 h. Audiogram revealed a low-frequency mild sensorineural hearing loss in the left ear prior to the procedure. By her 1-month follow-up, her hearing loss was back to normal. In our experience, an epidural blood patch is an effective treatment for post-dural puncture tinnitus. Its effects are instantaneous and complete resolution is achieved by 24 h
