Research has been done to evaluate the addition of zeolite to manure fertilizer. This research is aimed to review the advantages and disadvantages of zeolites as manure fertilizer additive. Investigation is carried out by different variables: zeolite particle size, zeolite concentration and curing time. The results show that zeolite particle sizes of â7 +10 mesh and â20 +48 mesh did not significantly different. Zeolite â compost mixture can dry very fast, just in 2 weeks curing time the residual water content is only 5-6%, while that on the controlled compost (without zeolite) is still 70%. Higher zeolite concentration will speed up the compost drying process. On the other hand, zeolite addition will increase the potassium content by 1.7â2% but it also increases NH3 volatilization, which will result in a lower N content. Higher zeolite concentration will give lower N content in the composite. It can be concluded that zeolite addition is suggested not applied to the fresh compost but just before the compost will be used in order to increase the nutrition efficiency.

Manure contains micro and macro nutrients which are essential for plant growth. During the decomposition process and after application to the soil, nutrients in manure especially nitrogen is easily volatile to the atmosphere and leaching by water. Zeolite has a high adsorption to ammonium ion, so the application of zeolite together with manure may improve the plant growth. The objective of this research is to evaluate the effect of manure and zeolite addition to the growth and absorption of plant nutrients of Ipomoea reptans. This research was conducted in green house of Department of Soil Science, Faculty of Agriculture, Bogor Agricultural University, from June until October 2004. Cultivation was conducted in two period. Immediately after the plant were harvested in first period, plant media were cultivated for the second period without addition of fertilizers. Addition of 20 ton/ha zeolite to the plant media influence the growth and absorption of nutrient higher than the other zeolite treatments. Nutrient residue of zeolite treatment is higher than the treatment without zeolite which is shown by higher production of Ipomoea reptans in the second planting period. Application of zeolite increase the growth of plant. Application of zeolite together with chicken manure gave higher growth and production compared with cattle manure.

Serang Municipality and Serang Regency in Banten Province are the buffer zones area of capital city Jakarta. Population growth in Serang Municipality in the year of 2010-2012 was 2.91%, and in Serang Regency in the year of 2000-2010 was 1.43%. It is eminent that increase of population would increase the consumption of water. The freshwater from unconfined aquifer is an alternative supply for domestic need, in addition to the supply from water utilities (PDAM). However, uncontrolled water pumping would cause the declining of water table; then influenced of seawater might occur. This study was conducted to determine whether the unconfined groundwater has been influenced by seawater. The study consisted of groundwater observation, measurement and groundwater collection (20 samples collected). Then, the samples were analyzed in laboratory, which consisted of flame photometric, volumetric, and visible spectrophotometric. Results showed that District of Pontang, Kasemen, Ciruas, and some areas in Kramawatu and Serang are the areas that were most affected by seawater. One location, SRG 33, in Tembakang village, Pontang District, has the highest content of electro-conductivity, salinity, sodium, chloride, and magnesium. That indicates that groundwater in this location is the most influenced by seawater.Kota dan Kabupaten Serang adalah dua wilayah yang terletak di Provinsi Banten, sebagai daerah penyangga Ibu Kota Jakarta. Pertumbuhan penduduk di Kota Serang pada tahun 2010-2012 mulai menunjukkan kenaikan yang cukup tinggi sebesar 2,91% dan di Kabupaten Serang dari tahun 2000-2010 sebesar 1,43%. Jumlah penduduk yang meningkat berdampak meningkatnya konsumsi air yang dibutuhkan. Airtanah tidak tertekan dapat menjadi alternatif penyedia air bersih selain PDAM, namun pengambilan airtanah tidak tertekan yang tidak terkendali dapat berpotensi menimbulkan penurunan muka airtanah (MAT), sehingga dapat memicu adanya pengaruh air laut ke airtanah tidak tertekan. Penelitian ini dilakukan untuk mengetahui sejauh mana kualitas airtanah tidak tertekan telah terpengaruh oleh air laut. Penelitian meliputi pengamatan, pengukuran dan pengambilan 20 conto airtanah, metode analisis berupa fotometri nyala, volumetri, dan spektrofotometri sinar tampak. Hasil penelitian menunjukkan bahwa beberapa lokasi yang telah terpengaruh oleh air laut secara umum terdapat di Kecamatan Pontang, Kasemen, Ciruas, sebagian Kecamatan Kramatwatu dan Serang. Satu lokasi di titik SRG 33 di Kp. Tembakang, Kecamatan Potang mempunyai kandungan DHL, salinitas, natrium, klorida, dan magnesium tertinggi dibanding lokasi lainnya, ini menunjukkan bahwa titik ini telah terpengaruh oleh air laut.

ABSTRAK Air gambut mempunyai derajat keasaman tinggi (pH antara 3-5), kandungan partikel tersuspensi rendah, dan intensitas warna tinggi berwarna merah kecoklatan dengan kandungan zat organiknya yang tinggi. Menghilangkan warna dan kandungan zat organik dilakukan percobaan dengan proses koagulasi-flokulasi. Proses diawali dengan menaikkan nilai pH hingga suasana basa dengan membubuhkan kaporit dan kapur tohor, menaikkan kandungan partikel tersuspensi melalui penambahan tanah lempung, dan kemudian tawas (aluminium sulfat) sebagai koagulan. Penambahan 0,05 gram kapur tohor, 0,10 gram kaporit, 0,30 gram lempung dan 0,40 gram tawas ke dalam 1000 ml air gambut serta pengadukan secara manual selama 30 detik, proses koagulasi pada pH 11 berhasil menghilangkan warna 99,20 % yakni dari 383,50 TCU turun menjadi 3,01 TCU, dan kandungan zat organik turun sebesar 98,15 % dari 385,87 mg/L KMnO4 menjadi 7,19 mg/L KMnO4. Baik warna maupun zat organik, keduanya menunjukkan nilai yang memenuhi persyaratan air minum.

ABSTRAK Pengambilan airtanah yang berlebihan menunjukkan bahwa dari tahun-ketahun di beberapa tempat telah mengalami penurunan kualitasnya, dan mengalirnya airtanah dari akuifer tidak tertekan ke akuifer tertekan. Analisis mengenai fenomena tersebut dilakukan dengan cara membandingkan tipe air dari kedua akuifer tersebut. Untuk keperluan itu, telah dilakukan penelitian airtanah di 20 lokasi yang tersebar di wilayah DKI Jakarta. Pengambilan conto airtanah terdiri dari 15 conto dari akuifer tidak tertekan, 12 conto pada akuifer tertekan atas, dan sembilan conto dari akuifer tertekan bawah. Hasil analisis kimia dengan metode spektrofometri serapan atom (AAS), volumetri, dan turbidimetri menunjukkan bahwa tipe airtanah pada akuifer 1, 2, dan 3, bertipe MgCl2, CaCl2, NaCl, , Na2SO4, NaHCO3, NaMix, dan Ca(HCO3)2. Tipe air NaCl mengindikasikan bahwa di Tongkol, Ancol, Marunda, Slipi dan Cempaka Putih telah dipengaruhi oleh garam, tipe ini banyak didapatkan pada akuifer 1. Sedangkan tipe anion bikarbonat banyak terdapat pada akuifer 2 dan akuifer 3. Masing-masing akuifer umumnya memperlihatkan tipe airtanah yang berbeda, hasil ini memberikan indikasi bahwa di lokasi penelitian tidak terjadi aliran airtanah secara vertikal.

ABSTRACT At the present time, more than 13 millions people live in Jakarta Area and it will increase in the near future. This population pressure increases the groundwater abstraction in the area and can cause groundwater, either quality or quantity, problems. The quality decreasing is marked by the appearance of some pollutants, such as nitrate pollutant which is produced by human activity, i.e. domestic waste, garbage leaching, and fertilizer over used. The analysis result of nitrate (NO3) content in groundwater was varied from 0.00 to 79,737 mg/l. The high content of nitrate were found in dug well of unconfined aquifer, while in the groundwater of confined aquifer the nitrate content is relatively low, < 4 mg/l . It is concluded that the presentation of those pollutant is caused by poor sanitation system and the presentation of nitrate pollutant is very much connected with un-control groundwater abstraction either for domestic or industry use. Keywords : Groundwater, Nitrate, Pollutant, Jakarta Groundwater Basin ABSTRAK Pada saat ini, wilayah DKI Jakarta di huni oleh lebih dari 13 juta penduduk dan cenderung bertambah di tahun-tahun mendatang. Pertambahan penduduk tersebut telah mengakibatkan terjadinya perubahan kondisi airtanah baik kuantitas maupun kualitas. Penurunan kualitas airtanah ditandai dengan terdeteksinya kehadiran beberapa polutan diantaranya polutan nitrat, yang sangat berhubungan dengan kegiatan manusia seperti pembuangan limbah domestik, pelindihan TPA, dan penggunaan pupuk yang berlebihan. Analisis kandungan nitrat (NO3-) pada airtanah memberikan hasil yang sangat beragam mulai 0,00 – 79, 737 mg/l. Nitrat yang cukup tinggi terdapat di sumur gali pada akuifer tidak tertekan, sedangkan pada akuifer tertekan kandungan nitrat masih sangat rendah, < 4 mg/l. Disimpulkan bahwa kehadiran polutan dalam airtanah disebabkan oleh sanitasi atau sistem buangan limbah yang kurang baik dan kehadiran polutan nitrat menunjukkan adanya keterkaitan dengan pemanfaatan airtanah yang tidak terkendali, baik untuk rumah tangga maupun untuk industri.

ABSTRAK Air permukaan dan airtanah dangkal pada sumur-sumur gali di sepanjang ruas-ruas sungai yang melintasi kota Cianjur ke arah hilir telah dianalisis untuk mengetahui tingkat pencemarannya. Air Permukaan dan Airtanah dangkal di Hilir kota Cianjur telah mengalami pencemaran pada tingkat yang berbeda. Pada air permukaan pencemaran ditandai dengan kandungan BOD tinggi sehingga air tidak dapat langsung dimanfaatkan sebagai bahan baku air minum, tetapi masih dapat dimanfaatkan sebagai air irigasi dan perikanan. Proses pemurnian kembali air di daerah studi tampaknya tidak akan terjadi karena jumlah rata-rata limbah yang masuk secara acak lebih besar daripada daya pulih aliran di daerah tersebut. Gejala pencemaran Nitrogen telah tampak pada air tanah dangkal, tetapi air masih dapat digunakan sebagai sumber air minum. Untuk mengantisipasi memburuknya keadaan di masa mendatang, perlu mulai difikirkan untuk mengelola sumberdaya air daerah ini dengan pendekatan hidrologi urban.
