Employee Performance Analysis Of Social Rehabilitation Pamardi Khusnul Khotimah Tangerang Selatan

The purpose of this study was to determine the effect of organizational culture, work ethic and discipline on the employees performance either partially or simultaneously of Social Rehabilitation Institution Pamardi Khusnul Khotimah at Tangerang Selatan. The results showed that organizational culture based on partial test was positive and significant effect on the performance of 76,2%, while work ethos can be good too was positive and significant effect on the performance of 72,2%, then work discipline also was positive and significant effect on the performance of 73%. The result of correlation coefficient (R2) of 76,7% can be summed up the effect of the variable X1 (organizational culture),  X2 (work ethos) and X3 (discipline) to variable Y (employees performance) where the relationship is positive. The results of calculation for 53.874 F-value further consultation with the F-table with dk = k numerator and denominator dk = (nk-1) with a 5% error level the importance of the F table = 2,80. Provisions applicable for F-value greater than F-table (53.874  > 2,80), it can be stated that the multiple correlation is significant. Thus the null hypothesis (H0) that states there is no effect between organizational culture, work ethos and discipline influence on employees performance is rejected, while the alternative hypothesis (Ha) is accepte

Freedom of contracts and dispute settlement between conventional banking and sharia banking

Purpose: This study aims to investigate the freedom of contract in conventional and sharia banking interpreted as an event of signing a credit agreement that raises the rights and obligations of the parties. Design/methodology/approach: The research design was qualitative, and the method was conducted by using a normative juridical method on a philosophical approach. Findings: The results showed that based on some lawsuit cases, in the conventional banking agreement, the customer submits the law to the credit rules made by the banking system. In Islamic banking agreements, the bank and the customers resolve the dispute to the existing agreement schemes in the sharia economic legal system. The results also reveal the construction of values contained in the principle of freedom of contract in each banking agreement. Practical implications: This paper can be used by management and legal experts to identifying the differences in principle of freedom of contract in conventional and sharia banking as a measure of justice in civil agreements in business law. Originality: This paper originally highlight that differences in principles and mechanisms for contracting affect procedures in dispute resolution.peer-reviewe

General Senior Secondary Education Financing in Indonesia

This report examines the policy options and financial implications of the expansion of senior secondary education in Indonesia. The government wishes to increase the gross enrolment rate from 70% to 85% by 2014 and aims for universal 12-year education by 2019. The approach adopted has been to: analyse current costs and funding arrangements through fieldwork and a review of secondary sources; consider the financing implications of achieving a set of minimum standards; review the current government funding provision; and examine a range of policy options for the expansion of senior secondary enrolments. The current funding of government senior secondary education is complex and varies throughout the country. It involves different levels of government providing financial support for infrastructure, salaries and operational costs. A common feature of the senior secondary sub-sector is its dependence on parental contributions. This has implications for school quality and for equity. The government's policy of designating some schools as 'international standard secondary schools' (RSBI) has inadvertently adversely affected equity.The study found considerable variation in the levels of cost and the amounts of available revenue among state senior secondary schools (SMA), with the RSBI being far better resourced than the rest. Salaries of government service teachers (PNS) are the responsibility of government. Those of teachers without PNS status, who are numerous in some schools, have to be paid for from other sources and almost invariably these costs fall on parents. The burden on parents comes in various forms. There are direct charges for fees and registration books and uniforms and there are indirect costs of transport and meals. There are also high opportunity costs of sending children to senior secondary school to set against the perceived returns of this level of schooling

On (4,2)-digraph Containing a Cycle of Length 2

A diregular digraph is a digraph with the in-degree and out-degree of all vertices is constant. The Moore bound for a diregular digraph of degree d and diameter k is M_{d,k}=l+d+d^2+...+d^k. It is well known that diregular digraphs of order M_{d,k}, degree d>l tnd diameter k>l do not exist . A (d,k) -digraph is a diregular digraph of degree d>1, diameter k>1, and number of vertices one less than the Moore bound. For degrees d=2 and 3,it has been shown that for diameter k >= 3 there are no such (d,k)-digraphs. However for diameter 2, it is known that (d,2)-digraphs do exist for any degree d. The line digraph of K_{d+1} is one example of such (42)-digraphs. Furthermore, the recent study showed that there are three non-isomorphic(2,2)-digraphs and exactly one non-isomorphic (3,2)-digraph. In this paper, we shall study (4,2)-digraphs. We show that if (4,2)-digraph G contains a cycle of length 2 then G must be the line digraph of a complete digraph K_5

Determining Finite Connected Graphs Along the Quadratic Embedding Constants of Paths

The QE constant of a finite connected graph $G$, denoted by $\mathrm{QEC}(G)$, is by definition the maximum of the quadratic function associated to the distance matrix on a certain sphere of codimension two. We prove that the QE constants of paths $P_n$ form a strictly increasing sequence converging to $-1/2$. Then we formulate the problem of determining all the graphs $G$ satisfying $\mathrm{QEC}(P_n)\le\mathrm{QEC}(G)<\mathrm{QEC}(P_{n+1})$. The answer is given for $n=2$ and $n=3$ by exploiting forbidden subgraphs for $\mathrm{QEC}(G)<-1/2$ and the explicit QE constants of star products of the complete graphs.Comment: 24 pages, 6 figure

Relokasi Stadion Lebak Bulus Jakarta

Stadion Lebak Bulus sebagai salah satu stadion kebanggaan warga Jakarta, merupakan homebase dari klub Persija Jakarta.Dahulu, stadion ini sering dipakai untuk penyelenggaraan event olahraga sepakbola seperti ISL (Indonesia Super League) ataupun pertandingan persahabatan dan ujicoba dengan negara tetangga. Namun, sejak tahun 2008, PT. Liga Indonesia memutuskan untuk tidak menggunakan Stadion Lebak Bulus karena kapasitasnya yang kurang memadai untuk menyelenggarakan pertandingan sepakbola tingkat regional, nasional, ataupun internasional. Dengan demikian, Stadion Lebak Bulus dianggap tidak memiliki nilai daya jualnya kembali. Di lain sisi, terdapat kabar yang menyatakan bahwa Stadion Lebak Bulus akan digusur karena bangunan tersebut terkena dampak pembangunan stasiun MRT (Mass Rapid Transit). Penggusuran ini dilakukan karena adanya penambahan luas lahan yang semula hanya dibutuhkan sekitar 7000 meter namun kini terjadi perluasan sebesar 1 hektar.Proyek yang telah lama terhenti di tahun 2005 ini pada akhirnya dilanjutkan kembali di tahun 2013.Pemilihan lokasi proyek MRT yaitu di Kawasan Lebak Bulus didasarkan pada nilai strategis dari kawasan tersebut.Lokasi ini dilalui berbagai moda transportasi umum massal sehingga nantinya diharapkan dapat mengakomodir transportasi tersebut untuk mencapai stasiun MRT. Mengenai penggusuran Stadion Lebak Bulus, hal tersebut telah dipertimbangkan secara matang oleh berbagai pihak, mulai dari pengelola stadion hingga pemerintah.Penggusurannya pun harus menaati Peraturan Menteri Pemuda dan Olahraga, bahwa untuk merobohkan sebuah stadion diperlukan sebuah stadion pengganti, sehingga nantinya Stadion Lebak Bulus harus direlokasi.Sebelum dilakukan penetapan lokasi, Pemda DKI Jakarta telah melakukan kajian terhadap beberapa lokasi pilihan, antara lain di Belakang Rumah Sakit Fatmawati, di Jl. Madrasah, tanah milik PAM Jaya dan di Jl. Ulujami Kecamatan Pesanggrahan.Lalu dari hasil kajian tersebut, maka terpilih lokasi di Ulujami.Lokasi tersebut dinilai strategis karena para penggemar sepakbola diberikan kemudahan untuk mengakses stadion, tidak hanya lewat jalan raya, namun bisa dengan menggunakan kereta.PT. KAI berencana untuk merevitalisasi kereta jurusan Serpong-Tanahabang.Selain itu, lokasinya tidak jauh dengan akses Tol Bintaro sehingga semakin mudah untuk dijangkau
