This study examined the water quality of Saguling Reservoir as potential raw water for Bandung metropolitan area. Determination of water quality in this study consisted of trophic status determination based on total phosphorus, total nitrogen (ammonia and nitrate), and water clarity. Data were obtained 4 times a year for 16 years (1999-2013). We determined the overall water quality status by comparing data with criteria specified in Ministerial Regulation (Permen) of the Environment Number 28 of 2009 on the Water Pollution Load Capacity of Lakes or Reservoirs. Data from 11 stations were analyzed, which indicated a hypertrophic state with very high pollution. Nanjung Post (upstream of the reservoir) had the highest levels of total P, total N, and chlorophyll a compared with the Muara Ciminyak Post and Muara Intake Post (the middle and downstream regions of the reservoir). Seasonal changes had no effect on the trophic status, regardless of dry, normal, or wet conditions.
Wakaf merupakan salah satu instrumen untuk mengurangi kemiskinan yang bertujuan untuk keadilan sosial ekonomi. Konversi saham syariah menjadi wakaf untuk keperluan produktif atau sosial. Saham syariah memiliki kriteria tertentu yang diatur dalam peraturan otoritas jasa keuangan (POJK), dan diklasifikasikan dalam daftar efek syariah (DES). Emiten yang tercantum dalam daftar efek syariah (DES) dan mengeluarkan wakaf saham atau pun dividen kepada nadzir atau lembaga yang mengelola wakaf. Sebagai bentuk kontribusi untuk kemajuan ekonomi umat. Namun dalam pelaksanaannya banyak wakaf saham yang diterima dari emiten yang sudah keluar dari daftar efek syariah (DES), sehingga banyak wakaf saham yang masih belum jelas statusnya karena waqif (emiten) sudah tidak masuk kriteria saham syariah. Hasil dari penelitian tersebut, peneliti menyimpulkan: pertama, pelaksanaan wakaf saham di Tabung Wakaf Indonesia (TWI) sudah sesuai dengan kriteria syariah dan juga telah terdaftar di Badan Wakaf Indonesi (BWI). Akan tetapi, masih adanya perusahaan (emiten) yang tidak sesuai dengan kriteria syariah yang telah mewakafkan sahamnya; kedua, terdapat emiten yang telah mewakafkan sahamnya, namun belum sesuai dengan kriteria daftar efek syariah (DES); ketiga, pelaksanaan wakaf saham telah sesuai dengan UU No. 41 tahun 2004, namun belum diatur secara spesifik terkait dengan wakaf saham. Berdasarkan kesimpulan tersebut, peneliti memperoleh temuan bahwa adanya wakaf saham dari emiten yang tidak sesuai dengan kriteria syariah disebabkan karena belum adanya ketentuan khusus yang mengatur wakaf saham, sehingga dalam pelaksanaannya berjalan tanpa aturan yang spesifk. Peneliti menyarankan hendaknya pemerintah dan Badan Wakaf Indonesia segera membuat Undang-undang dan peraturan tentang wakaf saham dan standar operasional prosedurnya agar wakaf saham berjalan semestinya dan mampu memberikan manfaat bagi kemajuan ekonomi umat.

This study aims to describe the effectiveness of online learning in Indonesian Language Courses (MKBI). The evaluation uses the Context, Input, Process, Product (CIPP) model. This qualitative research design uses descriptive evaluative. Data collection instruments used closed questionnaires, structured interviews, and documentation. Data processing techniques refer to the Guttman scale. The results showed the average value of the context evaluation aspects (0.92), input evaluation (0.85), process evaluation (0.86), and product evaluation (0.90). So, it can be concluded that MKBI's online learning at IKIP Siliwangi is very appropriate and effective.
Saguling Reservoir has a potential to be used as a raw water supply for Bandung Metropolitan Area (BMA), with the discharge of 1.622 dm·s−1. However, further studies are needed to ensure that the water quality is in accordance with the government regulations. This study shows that the reservoir’s P concentration was 315.0 mg·m−3 on average in 1999–2013. This value only meets the class III of government standards of water quality for the cultivation of freshwater fish, livestock, and to irrigate landscaping, but does not belong to the class I standard of 200 mg·m−3 for drinking water. The total-P concentration in wet, normal, and dry years was 796.3, 643.8, and 674.8 mg·m−3, respectively. The pollution load was highest in wet years due to the high levels of sediment. The pollution load of the reservoir did not exceed the class III classification of 29 405.01 kg·year−1. The pollution load in wet, normal, and dry years was 38 790.1, 25 991.9, and 23 929.0 kg·year−1, respectively. The phosphorus pollution is caused by the use of floating net cages in the reservoir, which makes it difficult to meet the standards. In wet years, the pollution load was higher than in normal and dry years. The P load could be higher in the wet season due to dilution and could probably decrease the pollutant concentration in the reservoir.
This paper describes about the philosophy and the embodiment prinsisp of Tauhȋdullah and al-‘adalah in ijarah and Ijarah Muntahia Bi-Tamlik (IMBT). In this paper will have the discussion on the definition of the principles put forward tauhȋdullah and al-‘adalah, the explanation of ijarah, Ijara Muntahia Bi-Tamlik (IMBT), the embodiment of the principle of ijarah and ijarah Tauhȋdullah Muntahia Bi-Tamlik (IMBT), the embodiment of the principle of al-ijarah and Ijarah Muntahia Bi-Tamlik (IMBT). And concluded that tauhȋdillah principle as a principle which provides binding rules between man and his lord, and al-‘adalah principle as a principle that will make an impact of harmony to human being, as with the values of justice there will be no party who feel aggrieved or oppressed.
