"ABSTRAKPotential Bankruptcy On Islamic Banking Sector Facing Business Environmental Changes This research aims is to evaluate the soundness of Islamic banks and to predict the bankruptcy potency from the Islamic banks. The methods that used on this paper are RGEC method and the modified altman z-score analysis. The RGEC is represents by NPF, LR, risk profile, ROA, NCOM, and CAR. The altman z-score is represents by the ratio of networking capital to total asset, retained earning to total asset, earning before interest and tax to total asset, and book value of equity to book value of debt. The result shown that the Islamic bank's soundness used RGEC methods is fit into healthy category in 2010-2014 periods. The altman z-score also show that the Islamic banks fit into safe zone in 2010-2014 periods."

"Saat ini, permasalahan sampah sudah menjadi permasalahan besar di Ibu Kota Jakarta. Setiap harinya manusia memproduksi sampah sebanyak 0,8 kg dan sampah rumah tangga-lah yang menjadi penyumbang terbesar sampah yang ada. Persepsi masyarakat terhadap pengelolaan sampah padat rumah tangga yang tepat dapat membantu mengatasi permasalahan tersebut. Penelitian ini bertujuan untuk mengetahui gambaran persepsi masyarakat di bantaran sungai terhadap perilaku pengelolaan sampah padat rumah tangga. Penelitian ini merupakan penelitian kuantitatif dengan metode deskriptif sederhana. Pengambilan sampel dalam penelitian ini dilakulcan secara acalc teratur/simple random sampling sebanyak 54 warga di wilayah RW. 02 khususnya pada RT yang dilalui sungai Kalisari (RT 07, 09, 10, 12). Data yang sudah terkumpul dianalisa dengan rumus univariat dan a 0,05 dan didapatkan hasil bahwa masyarakat memiliki tingkat persepsi yang positif (61%) terhadap pengelolaan sampah padat rumah tangga.

Currently, the problem of waste has become a major problem in the capital city of Jakarta. Every day people produce as much as 0.8 kg of garbage and household trash that was the largest contributor to the existing waste. Public perception of household solid waste management right can help overcome these problems. This research aims to reveal people's perception along the river to the behavior of household solid waste management. This is a quantitative research with use simple descriptive method. Sampling in this study were randomly regular/ simple random sampling from 54 residents in the area of RW 02 especially on the RT 07, 09, 10 and 12 that impassable of the Kalisari's river impassable. The data have been collected will be analyzed with univariat pattern and ot 0.05 and the result is that people have a positive perception of the level (61%) of household solid waste management."

"Query becomes one of the most decisive factor on documents searching. A query contains several words, where one of them will become a key term. Key term is a word that has higher information and value than the others in query. It can be used in any kind of text documents, including Arabic Fiqh documents. Using key term in term weighting process could led to an improvement on result?s relevancy. In Arabic Fiqh document searching, not using the proper method in term weighting will relieve important value of key term. In this paper, we propose a new term weighting method based on Positive Impact Factor Query (PIFQ) for Arabic Fiqh documents ranking. PIFQ calculated using key term?s frequency on each category (mazhab) on Fiqh. The key term that frequently appear on a certain mazhab will get higher score on that mazhab, and vice versa. After PIFQ values are acquired, TF.IDF calculation will be done to each words. Then, PIFQ weight will be combine with the result from TF.IDF so that the new weight values for each words will be produced. Experimental result performed on a number of queries using 143 Arabic Fiqh documents show that the proposed method is better than traditional TF.IDF, with 77.9%, 83.1%, and 80.1% of precision, recall, and F-measure respectivel.

Query menjadi salah satu faktor penentu dalam pencarian dokumen. Dalam sebuah query terdiri dari beberapa kata, dimana salah satunya menjadi key term. Key term adalah kata yang memiliki nilai informasi dan bobot lebih tinggi dibandingkan kata lain. Hal tersebut berlaku untuk semua jenis dokumen teks, termasuk dokumen fiqih berbahasa Arab. Penitik beratan pada key term dalam proses pembobotan kata memungkinkan terjadinya peningkatan relevansi pencarian. Di dalam pencarian dokumen fiqih berbahasa Arab, jika metode pembobotan kata yang digunakan tidak tepat, key term tidak akan memberikan pengaruh berarti. Oleh karena itu diusulkanlah sebuah metode pembobotan baru pada kata berbasis Positive Impact Factor Query (PIFQ) untuk perangkingan dokumen fiqih berbahasa arab. PIFQ dihitung menggunakan frekuensi kemunculan key term pada setiap kategori (mazhab) dalam fiqih. Semakin tinggi frekuensi key term tersebut pada suatu mazhab semakin tinggi pula nilainya pada mazhab tersebut, begitu pula sebaliknya. Setelah didapat nilai PIFQ, kemudian dilakukan perhitungan TF.IDF untuk setiap kata. Selanjutnya bobot PIFQ akan dikom-binasikan dengan TF.IDF sehingga menghasilkan bobot baru untuk masing-masing kata. Hasil dari pengujian yang dil-akukan pada sejumlah query dengan 143 dokumen fiqih berbahasa Arab menunjukan bahwa metode usulan dapat lebih unggul jika dibandingkan metode TF.IDF, dengan nilai precision, recall, dan F-measure masing-masing sebesar 77,9%, 83,1%, dan 80,1%."
