Abstract

Islam teaches and recommends us to do all the things in the life seriously and or-derly based on the norms established by the religion. Management means to regulate all the things in order to be well done, precise, in good order, and complete. This activity is declared in Islamic Doctrines. Therefore, if a business is carried out by the guidance of the norms of the Declared-Islamic Doctriness, the business will not only persue the ma-terial benefits,but also will hope the Favor and the Bless of Alloh/God. The business that is carried out based on the law of Islam is then termed by the Syariah Business Manage-ment. The material benefit gained from this business will have favor of Alloh/God and has the grant of Alloh/God in it.

Abstract

Penelitian dilakukan pada PT Buana Spring Foam di Purwokerto, yang memproduksi spring bed dankasur busa. Pokok masalah dalam penelitian ini adalah menyusun rencana kapasitas produksi kasurbusa sehingga mampu memenuhi permintaan konsumen yang beragam sesuai dengan yangdijadwalkan. Perencanaan kapasitas dilakukan dengan metode Rought Cup Capacity Planning (RCCP)yang memiliki empat langkah yang harus dilakukan. Pertama, melakukan peramalan dengan metodetrend, metode pemulusan dengan musiman, metode moving average, dan metode pemulusan.Kemudian menghitung perencanaan agregat dengan metode tenaga kerja tetap dan metodetransportasi atas dasar hasil peramalan. Selanjutnya dilakukan proses disagregasi dengan metodecut & fit. Kedua, menentukan waktu proses produksi. Ketiga, menghitung bill of capacity dengan caramencari standar hours pada setiap jenis produk. Keempat, menghitung kebutuhan sumber dayaspesifik dan membuat laporan RCCP. Sedangkan untuk kapasitas tersedia didapat dari perhitunganrencana produksi. Bedasarkan hasil perhitungan tersebut dibuat load profile yang menunjukanbahwa hasil penelitian terhadap jadwal induk produksi layak digunakan untuk proses produksikasur busa. Kelayakan ini dihitung berdasarkan kesesuaian antara total kapasitas tersedia 28224unit dengan kapasitas terpakai 19415 unit. Oleh karena itu kapasitas tersedia dapat memenuhikapasitas terpakai.

Abstract

Succinic acid (HOOC(CH2)2COOH) is commercial compound that primarily used in food products. This compound also used in textile industry for colouring process, drugs industry, paint, pernist and photography slice. Succinic acid usually produced in industry by chemical reaction and produce cyanide acid as by product. The objective of this research was to study the utilization of Pseudomonas sp. in produce succinic acid and to characterize of involved enzymes. The results showed that the enzyme optimally produce in log phase. The production rate of succinic acid formation was 0,982 mM/ml.h with the decrease of substrate consumption was 1,235 mM/ml.h. The yield of succinic acid during 81 hours fermentation was 81%. The optimum pH, temperature, Km and Vran were 7, 27°C, 90 mM, and 0,0002 mM/ml.h.

Abstract

ABSTRACT The gold mining wastewater effluent is potential source for isolating cyanides-degrading bacteria, since cyanide is commonly used in gold extraction process in the mining industry. An indigenous bacterial strain LP3, capable of growing on and utilizing of a high concentration of cyanomethane (up to 1.0 Molar), could be isolated from Cikotok gold mine effluent. Based on 16S rDNA sequence, the strain was identified as Rhodococcus pyridinivorans. During the growth on cyanomethane (CH3CN), ethanamide (CH3ONH2) and ethanoic acid (CH3COOH) were detected in the growth media, indicating that nitrile hydratase and amidase involved in the metabolism of the substrate. The involvement of both enzymes on the conversion of cyanomethane was also proved by our study on cyanomethane biodegradation using whole cells of R. Pyridinivorans LP3. Besides cyanomethane, the R. pyridinivorans LP3 could also utilize various aliphatic, aromatic, heterocyclic nitriles and amides as growth substrates. Base on these results, R. pyridinivorans LP3 is expected to be used as a potential candidate for biological treatment for cyanide-containing wastes, although further research is still needed, before being applied on a field scale.  Keywords: biocatalyst, cyanide degrading bacteria, gold mining, Rhodococcus pyridinivorans LP3
