Abstract

This experiment aimed to observe the effect of herbs (Black Cumin,Curcuma zeodharia,Curcumamangga, and Curcuma aeruginosa) supplementation on milk yield and milk quality (milk fat, milkprotein, milk lactosa and mastitis status) in lactating dairy cows suffering mastitis. Twenty cows in 2nd-4th lactation suspected mastitis subclinical (++) were used in the experiment. Completely randomizeddesign was used in this experiment with 5 treatments (A. Non Herb; B. Black Cumin; C. Curcumazeodharia; D. Curcuma mangga, and E. Curcuma aeruginosa) with four replicates per treatment. Thecollected data were analyzed by analysis of variance and difference between the treatment effects wastested by using Duncan’s Multiple Range Test. The results showed that supplementation of herbssignificantly increased (P<0.01) milk yield, milk protein, milk lactosa and significantly decreasedmastitis status and did not significant affect milk fat.

Abstract

The natural and socio-cultural environment of the Wonosobo community has various potentials that can be explored and developed to support the science learning process. Pranotomongso is a form of culture used by farmers to cultivate nature. This study aims to determine the application of ethnoscience-based integrated science learning to foster environmental awareness and student creativity. This research is a quantitative study using the True Experimental method, with a Posttest Only Control Design, the sampling technique is random sampling. The instruments used for data collection were tests and questionnaires to measure creativity and environmental awareness. The data analysis technique used one-party t-test. The results showed that ethnoscience-based integrated science learning can foster environmental awareness and student creativity and can improve environmental care and student creativity in ethnoscience-based integrated science learning, in the medium category. This research is very useful in showing how science works in society, and it is more applicable.

Abstract

PT Akat Srida Amri adalah perusahaan yang bergerak dalam pertambangan batubara dimana proses penambangan akan membuat cekungan saat mengambil material. Pada PT Akat Srida Amri penanganan masalah air belum terlihat maksimal dimana sump yang ada tidak dibuat sesuai dengan masuknya air ke front penambangan serta kapasitas pompa yang digunakan untuk memindahkan air dari sump ke settiling pond tidak sesuai dengan air yang akan dipompa. Oleh karena itu, penelitian ini bertujuan untuk mendesain kolam penampungan (sump) yang sesuai dengan perhitungan air yang masuk ke front penambangan serta pemilihan pompa yang sesuai agar air tidak menggenang dan menganggu aktivitas penambangan. Metode yang dilakukan untuk menentukan desain sump yaitu dengan menghitung data curah hujan selama 10 tahun terakhir yang kemudian akan didispersi, menentukan koefisien limpasan serta luasan catchment area. Setelah dilakukan analisis sesuai metode dispersi, perhitungan J. C. Gumbell, dan perhitungan debit air limpasan maka didapat hasil perhitungan debit air limpasan yang diperkirakan masuk sebesar 15.781,20915 m3/hari, sehingga rekomendasi rencana dimensi sump yang akan dibuat agar dapat menampung sesuai debit air limpasan serta sesuai KEPMEN 1827K/30/MEM/2018 yaitu panjang alas 65,5m, lebar alas 30m, panjang permukaan 81,5m, lebar permukaan 45m dan kedalaman 6m. Untuk penanganan pompa agar bekerja lebih efektif, PT ASARI harus menjadwalkan dan merealisasikan jam kerja pompa selama 10 jam perhari, meletakkan atau menanam tiang pengukur air di dalam sump, serta dapat juga melakukan penambahan engine pada mesin pompa agar kekuatan daya pompa dapat lebih tinggi lagi.
