Abstrak: Water is one of the basic necessities of human beings to make life and increase their welfare. Indonesia is located in the tropics and have raw water availability. Drought-prone was one problem in the raw water supply as a result of the uneven distribution of water in the region of Indonesia. Tangerang Regency is one of the areas of Indonesia's Banten Province has its challenges in the future to meet the needs of the raw water, due to the increasing population and decreasing ability of the environment both in quality and quantity in the raw water supply. This research aims to know the needs and availability of raw water in the near future. Water demand was analyzed by exponential approximation is a method, and water availability was analyzed based on linear equations obtained from linear regression using Microsoft Excel 2007. Water requirements were analyzed based on demand, such as the water needs for domestic, non-domestic, industrial, fisheries, livestock and irrigation. From the results obtained that level of water needs from 2010 to 2030 as a whole has increased, which for 2010 of 71,61 m3/sec, 2015 amounting to 72,86 m3/sec, by 2020 of 76,24 m3/sec, 2025 of 82,75 m3/sec, and 2030 of 95,35 m3/sec. While the total availability of water from 2010 to 2030 from water source river and groundwater degradation, which in 2010 of 143,17 m3/sec, 2015 amounting to 127,28 m3/sec, by 2020 of 114,02 m3/sec, 2025 of 100,75 m3/sec, and 2030 of 87,50 m3/sec. By 2030 water availability can’t meet water demand, with a water deficit -7,85 m3/sec.

Judul: Analisis Kebutuhan dan Ketersediaan Air Untuk Industri Besar di Kota Tangerang,
Abstrak: Water is one of the main requirements for production process and other activities in the industry. Actually, industries required water supply with certain qualities as well as its quantity and continuity to support production process. Utilization of water resources must be done wisely, to keep environmental equilibre. This study was conducted in March-May 2014 in Tangerang City, Banten Province. This research identified the use of water in industry and analysis of industry supply and the demand of water in the city of Tangerang using regression methods. This research needed data of industrial water usage, amount of worker and production total. Water availability data were obtained from the "Balai Besar Wilayah Sungai Ciliwung Cisadane". Based on Batu Beulah Station, the average discharge of Cisadane river was 68.47 m3/s, and groundwater potential was 3.21 m3/s. According to regulation 21% of surface water and 20% of groundwater can be used for industrial activities, so total availability of water in Tangerang City was 481,308,739 m3/year. It meaned that water availability in Tangerang could support 487 big industries. Result analysis showed that based on industrial growth rate Tangerang City will have 487 industries in 2073.

Judul: Penggulung daun Sylepta sp. (Lepidoptera: Crambidae) pada Boehmeria minuticymosa (Urticaceae):
Abstrak: Sylepta sp. (Lepidoptera: Crambidae) merupakan kelompok hama yang bersifat polifag. Larva hama ini menyebabkan daun menggulung. Salah satu tanaman inang hama ini adalah gulma Boehmeria minuticymosa N. Acharya & Yonek (Urticaceae). Larva sering diparasit oleh beberapa parasitoid, sehingga bisa bermanfaat sebagai inang alternatif parasitoid dalam pengendalian biologi. Tujuan dari penelitian ini yaitu mengamati beberapa aspek biologi hama ini dan parasitoidnya pada B. minuticymosa. Penelitian dilaksanakan di Laboratorium Biosistematika Serangga, Departemen Proteksi Tanaman, Fakultas Pertanian, Institut Pertanian Bogor, dari bulan Februari hingga Agustus 2018. Larva Sylepta sp. diperoleh dari lapangan dan dipelihara di laboratorium. Aspek biologi yang diamati meliputi jumlah instar larva, stadium larva dan pupa, lama hidup imago, dan parasitoidnya. Hasil penelitian menunjukkan bahwa Sylepta sp. memiliki empat instar. Rata-rata stadium larva dan pupa adalah 19.59 dan 8.33 hari. Larva menggulung daun dan memakannya dari bagian dalam daun. Pupa berwana cokelat gelap. Lama hidup imago jantan dan betina adalah 4.18 dan 6.09 hari. Parasitoid dari hama ini termasuk Ordo Hymenoptera, Famili Braconidae dan Bethylidae (parasitoid larva) dan Chalcididae (parasitoid pupa).
