Rumen Fermentation, Blood Metabolites, and Performance of Sheep Fed Tropical Browse Plants

The in vitro study was designed to evaluate total gas production, dry matter degradability (DMD), and VFA profile; while in vivo study was designed to evaluate nutrient intakes, blood metabolites, and performance of sheep fed native grass mixed with Calliandra calothyrrus (CC), Leucaena leucochepala (LL), Moringa oleifera (MO), Gliricidea sepium (GS), and Artocarpus heterophyllus (AH). The best three from the in vitro results were used to formulate diets in in vivo study. Sixteen male growing sheep (average BW 20 kg) were fed 100% native grass (NG) as control; 70% NG + 30% GS; 70% NG + 30% MO; and 70% NG + 30% AH. Nutrient consumptions, DMD, blood metabolites, and sheep performances were analyzed by using Completely Randomized Design. The in vitro results showed that the total gas production and DMD of CC and LL were the lowest (P<0.05) while the highest was found in GS, MO, and AH treatments (P<0.05). Meanwhile, the in vivo results showed that nutrient intakes (DM, CP, and CF) of GS and AH rations were the highest. The ADG, concentration of albumin, and globulin in all treatments were similar, while total serum protein, triglycerides, and glucose concentration in MO and AH rations were higher than others. Serum cholesterol concentration in MO ration was the lowest, meanwhile the concentration of IgG was the highest (P<0.05). Supplementation of 30% MO was the best choice for optimum rumen fermentation and maintaining health status of local sheep

Penentuan Konduktivitas Termal Logam Tembaga, Kuningan, dan Besi dengan Metode Gandengan

Penelitian ini bertujuan untuk menentukan konduktivitas termal logam tembaga, kuningan, dan besi dengan metode gandengan. Konduktivitas termal bahan merupakan ukuran kemampuan suatu bahan untuk menghantarkan panas. Pada materi ini mahasiswa diharapkan lebih interaktif karena berhubungan dengan kehidupan sehari-hari. Jika pembelajaran yang disampaikan diiringi dengan eksperimen maka akan lebih memudahkan memahami materi konduktivitas termal. Metode gandengan ini merupakan salah satu metode yang baru yang dapat dilakukan dengan cara mendekatkan dua buah logam untuk dipanasi. Alat ini terdiri dari slide regulator merk TDG, amperemeter merk SP-20D, termokopel, penerjemah termokopel, dan jangka sorong. Bahan yang digunakan dalam peneitian ada tiga macam logam yaitu logam tembaga, kuningan, dan besi. Penentuan konduktivitas termal bahan ini dilakukan dengan logam yang telah dililiti elemen pemanas (nikelin) yang dipanaskan. Kemudian divariasi nilai tegangan listrik (V) antara 5 V-25 V. Diukur arus listrik (i) dan diukur perbedaan suhu (ΔT ) pada ujung-ujung logam. Selanjutnya dari data Vi terhadap ΔT ini dilakukan dengan regresi linier. Nilai konduktivitas termal diperoleh k = (3,5 0,1) ×102 Wm-1K-1untuk tembaga; k = (1,0 0,1) ×102 Wm-1K-1untuk kuningan; dan k = (0,8 0,0) ×102 Wm-1K-1 untuk besi

Analisis Kandungan Co2 dengan Sensor dan Berbasis Logger Pro di Daerah YOGYAKARTA

Penelitian ini bertujuan untuk menganalisis kandungan CO2 di daerah Yogyakarta dengan menggunakan sensor CO2 dan logger pro. Kota Yogyakarta setiap tahunnya mengalami kepadatan penduduk yang menyebabkan pesatnya pemakaian kendaraan bermotor juga. Ini yang menyebabkan tingkat polusi udara di kota Yogyakarta juga semakin buruk akibat polusi kendaraan bermotor maupun industri. Kandungan CO2 yang seharusnya di atmosfer bumi sebesar 381 PPM. Dalam penelitian ini menganalisis kandungan CO2 di sepuluh tempat keramaian di Yogyakarta. Penelitian ini menggunakan sensor gas CO2 Vernier dan di analisis menggunakan software logger pro. Ketika sensor CO2 bekerja selama 5 menit akan muncul pulsa kandungan CO2 pada logger pro, kemudian dicari rata-rata kandungan CO2. Hasil penelitian ini dapat diperoleh uji kandungan CO2 yang paling tinggi adalah di daerah 0 KM Yogyakarta sebesar 973,2 PPM. Hasil ini melebihi nilai batas ambang rata-rata yang seharusnya di atmosfir bumi yaitu 381 PPM. Oleh karena itu perlu ditanami pepohonan dan mengurangi emisi kendaraan bermotor agar tingkat kandungan CO2 di kota Yogyakarta semakin menurun

Uji Konfirmasi dan Penetapan Kadar Morfin dengan Klt-spektrofotodensitometri

Screening and determination test of morphine using TLC-Spectrophotodensitometry method have been studied. Screening test based on the hRfc – value and the correlation value between detected spectrum and reference. The analysis results were improved by using the shift of spectrum reaction. The maximal result of screening test was obtained when determinate the hRfc-value with error window of three and the spectrum correlation above 0.90. The reaction of spectrum shift showed that morphine spectrum was not significantly changed after plates sprayed with HCL 10% and KOH 0.1 M so that could be used to increasing the analysis result of substance identity determination. Validation of method showed precision of method was 1.69%, the limit of detection 93.1 ng/spot and the limit of quantitation was 310,3 ng, percentage recovery of morphine from plasma was 106.34 ng ±10.79 (10.1%). TLC Spectrophotodensitometry could be used as simple and cheap method for screening and determination test of the morphine
