Abstract

PT. X merupakan pembangkit listrik dengan daya yang dihasilkan sebesar 3 X 330 MW. Untuk memenuhi target produksi setiap hari dibutuhkan kelancaran proses suplai batubara dari pulverizer menuju burner boiler, sehingga perlatan pulverizer dituntut untuk selalu dalam kondisi handal. Salah satu permasalahan unit 1 PT X pada tahun 2018 adalah banyaknya downtime pada peralatan pulverizer yang merupakan peralatan vital dalam proses produksi listrik. Dibutuhkan solusi untuk menyelasaikan permasalahan tersebut dengan menganalisis penyebab dan dampaknya terhadap daya yang dihasilkan serta menemukan solusi akhir. Penelitian ini bertujuan menganalisis dampak keandalan system pulverizer terhadap daya yang dihasilkan PLTU PT. X dengan menentukan: kegagalan dengan frekuensi paling banyak, nilai keandalan tiap pulverizer dan system pulverizer, dampak keandalan system pulverizer terhadap daya yang dihasilkan. Hasil penelitian menunjukan bahwa kegagalan terbanyak pada system pulverizer adalah plugging pada inlet pulverizer, nilai keandalan untuk Pulverizer 1A = 0.6%, 1B = 1.39%, 1C = 0.18%, 1D = 2.87%, 1E = 2.5%, 1F = 12.45% dan nilai keandalan system pulverizer adalah 18.8%. Hal ini mengakibatkan kehilangan dayanya sebesar 3948.6 MW dan berdampak berkurangnya pendapatan sebesar Rp. 3,139,137,000.00.

Abstract

Penelitian ini dilakukan untuk mengetahui karakteristik dan sensitivitas dari transduser gaya jenis Extended Octagonal Ring (EOR). Analisis dibagi menjadi dua yaitu menggunakan metode elemen hingga dan pengujian eksperimental. Sensitivitas EOR ditentukan melalui pengujian eksperimental dengan pembebanan vertikal 100 N hingga 500 N. Analisis metode elemen hingga menggunakan software ANSYS dengan pembebanan 3 kN hingga 15 kN disesuaikan dengan beban kritis buckling. Hasil pengujian menunjukan linearitas dan sensitivitas silang pada EOR. Pengujian eksperimental diperoleh sensitivitas EOR diperoleh sebesar Kv = 0.1999 μs.N-1 untuk gaya vertikal dan Kh = 0.0056 μs.N-1 untuk gaya horizontal dengan sensitivitas silang sebesar 2.8 %. Analisis metode elemen hingga diperoleh sensitivitas EOR diperoleh sebesar Kv = 0.1858 μs.N-1 untuk gaya vertikal, Kh = 0.0018 μs.N-1 untuk gaya horizontal dan Km = 0.007 μs.N-1 untuk momen dengan sensitivitas silang sebesar 0.9 % dan 3.76 %. Selanjutnya, EOR dapat digunakan sebagai transduser untuk analisis buckling.

Abstract

Wealth is something that humans want to have for various purposes and needs, be it basic needs, shopping, bus iness and social needs. The sense of belonging to the wealth that affects whether the property will have a positive or negative impact on the surrounding area. The concept of zuhud which is often known in Sufistic knowledge can also be very good if used in wealth ownership. Because someone who uses the concept of zuhud in wealth ownership will be more oriented to the world, not to the world. So that the purpose of finding and owning property is only as a means to achieve its ultimate goal in the world, namely to add goodness to Allah, carry out Islamic Shari'ah and worship Allah.

Abstract

Since the introduction of Islamic banking in 1991, the Islamic economy has experienced significant growth. Many products and services have been introduced by sharia banks and other financial institutions to facilitate this need, with reference to various fatwas from the National Sharia Council - Indonesian Ulema Council (DSN-MUI). One of the services provided by sharia banking is multiservice financing, which is recognized as sharia valid through DSN-MUI Fatwa No: 44/DSN-MUI/VIII/2004. The focus of this research is on kafalah contracts, because DSN-MUI Fatwa No: 44/DSN-MUI/VIII/2004 allows multiservice financing using ijarah and kafalah contracts. Kafalah bil ujrah, as defined in the fatwa, is a guarantee transaction provided by a bank in exchange for wages. However, the legality of this contract is controversial because the arguments put forward by DSN-MUI are different from the standard arguments applied by AAOIFI, which actually prohibits it. Therefore, creative thinking is needed to find alternative contracts that can overcome this controversy and enable further developments in Islamic banking. The problem studied in this research is the concept of the kafalah contract according to the fatwa of the two institutions and the method of determining the fatwa (istinbath) of the two institutions regarding the kafalah contract. This research is library research with qualitative analysis. The method used is descriptive-comparative with the bayani, ta'lili and istislahi approaches.
