Abstract

Jaminan mutu merupakan suatu cara untuk meyakinkan pelanggan bahwa kualitas hasil uji laboratorium yang dihasilkan sudah memenuhi persyaratan. Kestabilan pada suatu alat pengukuran merupakan hal yang penting. Hal ini diperlukan untuk memperoleh hasil pengukuran dan mutu produk yang baik. Penelitian ini dilakukan untuk melihat kestabilan suatu metode pengukuran protein pada kue kering sehingga dapat menjamin kualitas data yang dihasilkan. Data yang digunakan adalah data akurasi dan presisi pengujian protein pada kue kering yang dinutrifikasiikan tepung ikan nila. Data tersebut dianalisis menggunakan metode Statistika Pengendalian Mutu dengan diagram grafik kendali X sebagai grafik kendali mutu akurasi dan grafik kendali (R) sebagai grafik kendali presisi. Adapun hasil yang diperoleh adalah, garis kendali pada grafik X, akurasi dapat diterima karena data berada diantara garis UWL dan LWL (2SD), dan data akan diperingatkan jika data tersebut berada diantara UCL dan LCL. Pada grafik R, presisi dapat diterima karena data berada di bawah antara 2 sd atau dibawah garis UWL. Data dinyatakan outlier jika data akurasi dan presisi berada diluar garis UCL dan LCL.

Abstract

Empty fruit bunches (tankos) are a by-product, which is equal to the amount of CPO, which is 23%. Several attempts have been made to utilize tankos as a growing medium for mushroom, but these efforts have not been optimal. This is because they only take the edible mushroom product once, even though the waste still has the potential as a growing medium for the next mushroom, as well as the potential for compost. The purpose of the study was to determine the effect of new EFB, EFB that have been used once, and twice (used EFB I and used EFB II) on the pattern and daily production of straw mushrooms on the pilot plant scale.Pilot plant scale research has been carried out at CV Lintang Agro Farm Raman Adji East Lampung with three treatments, namely new EFB, used EFB I, and second-hand boarding houses. The study was repeated two times. The raw materials used are EFB, lime, katul, mushroom seeds, second-hand tankos I and second-hand EFB. The stages of the research process began with the preparation of EFB, the process of making edible mushrooms and observing the results of the research. The results showed that (1) EFB could be used as a planting medium for straw mushrooms 3 times, (2) the most productive production of straw mushrooms with EFB media was carried out until day 20 of the inoculation process, and (3) planting straw mushrooms on EFB media was able to reduce cellulose, hemicellulose, and lignin content significantly.

Abstract

The palm oil industry produces POME (Palm Oil Mill Effluent) liquid waste. POME is generally brownish, has an odor, and contains dissolved and suspended solids in the form of colloids and oil residue with a high Chemical Oxygen Demand (COD) content. Currently, the POME processing system still uses a conventional system known as the open pond system. This research aims to reduce the burden of organic materials related to removing COD levels, and color. It can solve the technical and operational obstacles of conventional processing systems. One of the extensive efforts to process POME is to develop Fenton-based photocatalytic technology, namely the Fenton-TiO2-UV method. Photocatalytic technology has several general processes involving semiconductor photocatalysts such as TiO2 and photon (UV) energy sources. In this study, the Fenton-TiO2-UV method was used with variations in the Fenton molar ratio of 1:100, 1:200, 1:300 (v/v), reaction times of 30, 60, and 90 minutes with TiO2 concentration 0.6% and uses 2 UV lamps (15 watts). This study achieved the maximum color degradation percentage at a Fenton molar ratio of 1:100 with a reaction time of 30 minutes, namely 95.28%. Meanwhile, the maximum COD degradation percentage was achieved at a Fenton molar ratio of 1:100 with a reaction time of 90 minutes, namely 98.88%.
