Abstract

Forecasting is an activity to get an estimate of the value that will appear in the future by paying attention to past events. Forecasting can be used as decision support in determining a policy in various fields. Forecasting can be done using statistical methods such as regression analysis, trend analysis, MA, and ARIMA. In this paper, the fuzzy time series markov chain method will be forecast which will be applied to rice production data in D.I. Yogyakarta Province. The fuzzy time series markov chain method was chosen because it does not need to meet certain assumptions so that the fuzzy time series markov chain can be applied to time series data with stationary and non-stationary patterns. This study aims to analyze fuzzy time series markov chain for rice production forecasting. This study uses time series analysis. The data used in this research is secondary data. The data used in this study is data on rice production in D.I. Yogyakarta Province in 1970-2017 taken from the website www.pertanian.go.id. Historical data consists of 48 data. Solving this research problem using fuzzy time series markov chain method. The results of the study show that forecasting with 11 fuzzy sets is declared the best forecast with a mean absolute percentage error of 4.156%. .

Abstract

Kapok (Ceiba pentandra L.) is traditionally used in medicine. Based on the phytochemical screening, the leaves contain phenolic compounds, including flavonoids and tannins. The method used to determine the total phenol content was the Folin-Ciocalteu method using gallic acid as standard solution. The linear regression equation obtained on measured at 765 nm is y = 0.0054x + 0.0272 with determination (r) and correlation coefficient (R2 ) of 0.9994 and 0.9997. Total phenolic content in ethanol extracts is 89.185 µg/ml calculated as gallic acid. Meanwhile, determination of flavonoid content used comparison standard of quercetin used the AlCl3 method. Measuring at a wavelength of 510 nm gives a linear regression equation y= 0.122 + 0.003x with r = 0.9984 and R2 = 0.9960. Flavonoid content in kapok leaves is 1.6287% w/w calculated as quercetin.

Abstract

Telah dilakukan penelitian tentang Penentuan Efek Antiinflamasi Air Rebusan Daun Sisik Naga (Deymoglossum piloselloides L.Presl) Terhadap Tikus Putih Jantan. Sebanyak 15 ekor tikus putih jantan yang berumur 2-3 bulan dengan berat badan 150-200 gram. Tikus putih jantan dibagi menjadi 5 kelompok. Kelompok I (normal) diberi aquadest 5 ml, Kelompok II (kontrol obat) diberi larutan Natrium Diklofenak sesuai dosis dan berat hewan uji, Kelompok uji : kelompok III, IV, V masing-masing diberi larutan uji dengan konsentrasi 10%, 15%, 20%. Metode yang digunakan adalah pembentukan udem buatan pada telapak kaki tikus. Sebagai penginduksi udem digunakan karagen 0,2 ml secara subcutan. Parameter yang diamati adalah penurunan volume udem setelah pemberian zat uji, kemudian hitung rata-rata udem, % udem, % inhibisi dan dilanjutkan dengan menghitung kekuatan efek zat uji dibandingkan dengan obat. Dari penelitian yang dilaksanakan, dapat disimpulkan bahwa kekuatan efek zat uji dibanding dengan obat untuk konsentrasi 10% memiliki kekuatan efek sebesar 62,22%, konsentrasi 15% memiliki kekuatan efek sebesar 61,02% dan konsentrasi 20% memiliki kekuatan efek sebesar 86,22%.

Abstract

Tuntutan konsumen akan kualitas pelayanan kefarmasian mengharuskan adanya perubahan pelayanan, yang biasanya berorientasi pada produk obat, menjadi perubahan pelayanan yang berorientasi pada konsumen. Dengan penerapan pelayanan kesehatan, kepuasan menjadi bagian yang integral dan menyeluruh dari kegiatan layanan kesehatan. Apotek selaku penyedia jasa dituntut memberikan pelayanan yang terbaik untuk mencapai kepuasan masyarakat. Penelitian tentang pengaruh kualitas pelayanan farmasi terhadap kepuasan konsumen (pasien) di apotek x kota Bukittinggi merupakan penelitian deskriptif menggunakan kuisioner yang disebarkan kepada 50 responden yang melakukan pengambilan obat dengan resep di apotek tersebut. Jenis penelitian adalah observasional pendekatan cross sectional. Uji statistik yang digunakan menganalisis hubungan antar variabel menggunakan uji statistik pearson product moment. Hasil penelitian menunjukkan ada hubungan kenyamanan, ketersediaan obat, harga obat, kecepatan pelayanan, pemberian informasi obat, kemudahan pelayanan dengan kepuasan pasien. Hasil penelitian menunjukkan bahwa responden sudah merasakan puas terhadap mutu pelayanan di apotek x kota Bukittinggi untuk kelima dimensi , yaitu Tangibles (bukti langsung) dengan skore 2,89, Reliability (keandalan) dengan skore 2,98, Responsiveness (ketanggapan) dengan skore 3,03, Assurance (jaminan) dengan skore 2,65, Empaty (empati) dengan skore 2,79. Dapat disimpulkan responsiveness yang paling banyak disukai dari kelima variabel terhadap kepuasan konsumen (pasien) di apotek x kota Bukittinggi

Abstract

An ordinary protective reaction to tissue damage brought on by physical trauma, chemical agents, or harmful microbiological agents is inflammation. The kebo excerpt plant has significant amounts of flavonoids, which have anti-inflammatory and antioxidant properties. This study used the artificial udema method to determine the anti-inflammatory effects of Kebo Petikan leaves (Euphorbia hirta L.) ethanol extract in female white rats. This study applied a subcutaneous 1% carrageenine inducer as an anti-inflammatory drug on the soles of rats' feet. Following the injection of the test material at doses of 26 mg, 52 mg, and 104 mg, a decrease in volume was the metric that was observed. The results of the study showed the anti-inflammatory effect of ethanol extract of kebo petikan leaves at a dose of 26 mg/5ml had a strength of 32.3%, a dose of 52 mg/5ml had a strength of 78.48 %, and a dose of 104 mg/5ml had a strength of 91.46% compared to drugs.

Abstract

For humans, carbohydrates are a crucial nutrient that the body uses to produce energy. Additionally, carbohydrates aid in the body's digestion of extra protein. White rice flour (Oryza sativa L.) is a common energy source in the community with a high carbohydrate content. This research was done to find out how different hydrolysis times affected the amount of carbohydrates in white rice flour (Oryza sativa L.). The Schoorl Luff method is used to determine the carbohydrate content of commercial white rice flour. HCl 1 N was used as a catalyst to hydrolyze white rice flour, with different hydrolysis periods of 60 minutes, 90 minutes, 120 minutes, 150 minutes, and 180 minutes. A schoorl luff, a source of Cu2+, was used to assess the hydrolysis results and titrated iodometrically. With a time of 180 minutes and a weight-to-water ratio of 63.99%, the findings of determining the ideal carbohydrate content in commercial white rice flour were obtained.
