Water spinach (Ipomoea sp.) is a plant that is commonly consumed by the public. Shifting cultivation, distribution and sales that are not protectedÂ make vegetables easily contaminated by pollutants in the environment, one of the lead element. This study was conducted to determine the element content of Pb in water spinach sold in three traditional markets Cilandak subdistrict, South Jakarta. This study was conducted from February-March 2014 by using Atomic Absorption Spectrophotometer instrument (AAS) method flame. Analysis of the data using Analysis of Variance (ANOVA) with a confidence level of 95 %. If there are any differences, then followed by Duncan's Multiple Range Test. The Maximum Tolerable Intake (MTI) test to determine the maximal consumption of watercress with a particular assay with an approximate weight of 60 kg. Based on this research, the element content of lead in water spinach in three traditional markets District of Cilandak ranged from 1.22 to 22.06 mg/kg. No significant effect on the three traditional markets District of Cilandak location. Organ roots have high levels of lead element compared to levels in the leaves and stems. The entire test sample had levels of lead element above SNI 7387:2009 maximum threshold of 0.5 mg/kg so They are not safe for consumption. Average maximum weight of kale on the three traditional markets in Sub Cilandak that may be consumed per week in the organs of leaves and stems ranged from 0.1492 to 0.6032 kg.

Industry, homes activites, and aquaculture around situ or lake could contaminate and affect the water quality. This study aimed to determine the diversity of phytoplankton and water pollution level in Situ Bulakan Kota Tangerang based on saprobite index. The research was conducted on December 2014 until March 2015 at Situ Bulakan Kota Tangerang. Observations were made based on 4 points sampling with three repetitions for one day that could represented existing condition. Sampling sites in this study were at inlet flow, middle, outlet, and alleged utilized areas such as floating fish net. The result showed 26 species of phytoplankton from four classes, namely 9 species of Cyanophyceae, 4 species of Bacillariophyceae, 11 species of Chlorophyceae, and 2 species of Euglenophyceae with moderate diversity index (H' = 1.77─2.05). Monoraphidium sp. was a species dominated in Situ Bulakan Kota Tangerang which was found 215 individuals. So it can be said as saprobite bioindicator. Saprobite index in Situ Bulakan Kota Tangerang showed moderate to severe contaminated with α-mesosaprobic (0.14).

AbstrakIkan sapu-sapu (Pterygoplichthys pardalis) memiliki potensi dijadikan bahan pangan alternatif karena ketersediaannya melimpah di Indonesia. Daging ikan sapu-sapu dapat dijadikan abon yang harus sesuai dengan SNI. Pengolahan abon menggunakan minyak menyebabkan abon mudah mengalami kerusakan sehingga diperlukan metode untuk memperpanjang masa simpan. Tujuan penelitian ini untuk mengetahui karakteristik abon ikan sapu-sapu hasil radiasi gamma berdasarkan analisis proksimat, jumlah mikroba, kapang, dan organoleptik melalui uji hedonik. Daging ikan sapu-sapu diolah menjadi abon lalu diiradiasi dosis 0, 5, 10, dan 15 kGy kemudian disimpan selama 30 hari pada suhu ruang. Hasil penelitian menunjukkan bahwa iradiasi sinar gamma mampu memperpanjang masa simpan abon ikan sapu-sapu selama 30 hari. Nilai gizi protein, lemak, dan jumlah mikroba abon ikan sapu-sapu yang diiradiasi sinar gamma memenuhi syarat ketetapan abon ikan sesuai dengan SNI 01–3707 tahun 1995, kecuali untuk nilai kadar air dan kadar abu abon. Iradiasi sinar gamma mampu menekan pertumbuhan mikroba dengan dosis terbaik 15 kGy. Dosis 15 kGy merupakan dosis yang paling diterima pada parameter rasa diuji organoleptik. Penelitian ini dilakukan untuk mengetahui kelayakan abon ikan sapu-sapu dengan syarat mutu abon ikan berdasarkan SNI, menentukan dosis iradiasi dalam pengawetan abon ikan sapu-sapu dan mengetahui minat konsumen terhadap abon ikan sapu-sapu.AbstractArmored catfish (Pterygoplichthys pardalis) has potential to be used as alternative foodstuffs because its abundant in Indonesia. Armored catfish meat can be processed into shredded in accordance with provisions SNI value so it can be consumed. Shredded cooked processed used oil that will causes stale easily, there must be a method that can extend the shelf life of shredded. The purpose of this research was to determine the characteristics of shredded fish from gamma radiation based on proximate analysis, the number of microbes, molds, and organoleptics through hedonic tests. Armored catfish meat is processed into shredded and irradiated in doses 0, 5, 10, and 15 kGy and then stored for 30 days. The parameters measured were water content, ash content, protein, fat, microbial count, mold and organoleptic test. The results showed that gamma ray irradiation was able to extend the shelf life of the shredded fish for 30 days. The nutritional value of protein, fat and the number of microbial armored catfish shredded irradiated by gamma rays meet the requirements of the nutritional of shredded fish in accordance with SNI 01–3707 of 1995, except for ash content and water content. Gamma ray irradiation can reduce microbial growth with the best dose 15 kGy. Dose 15 kGy was a significant dose of the taste parameters in the organoleptic test. This research was conducted to determine the feasibility of shredded fish with SNI requirements, to determine the dose of irradiation in preserving shredded fish and to determine consumer interest in shredded fish.

AbstrakPencemaran tanah oleh logam timbal (Pb) merupakan salah satu bentuk pencemaran yang sangat berbahaya bagi mahluk hidup. Salah satu tanaman bioakumulator penyerap logam berat di lingkungan adalah tanaman bayam (Amaranthus tricolor L.). Tujuan dari penelitian ini adalah untuk menganalisis pengaruh aplikasi pupuk mikoriza terhadap akumulasi Pb pada akar, batang, dan daun serta pertumbuhan tanaman bayam. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan perlakuan dosis pupuk mikoriza, yaitu 0 g, 5 g, 10 g, dan 15 g per polybag. Jumlah Pb yang diaplikasikan ke media tanam adalah 5 ppm per polybag. Akumulasi Pb tertinggi terdapat pada tanaman bayam dengan perlakuan 5 g pupuk mikoriza. Rata-rata akumulasi Pb di akar, batang, dan daun pada perlakuan ini berturut-turut adalah 103,57 ppm; 36,67 ppm; dan 8,60 ppm. Pertumbuhan tanaman bayam pada perlakuan 5 g pupuk mikoriza lebih baik dari perlakuan lainnya, yaitu memiliki rata-rata tinggi tanaman dan jumlah daun tertinggi pada minggu ke-4 (9,7–12,5 cm dan 6,9–8,6 helai). Aplikasi pupuk mikoriza dapat meningkatkan akumulasi Pb pada akar, batang, dan daun serta meningkatkan pertumbuhan tanaman bayam pada dosis 5 g per polybag.AbstractSoil pollution by lead (Pb) is a form of pollution that is very dangerous for living creatures. One of the bioaccumulator plants that absorb heavy metals in the environment is spinach (Amaranthus tricolor L.). The aim of this research was to analyze the effect of mycorrhizal fertilizer application on Pb accumulation in roots, stems and leaves as well as spinach plant growth. This research used a completely randomized design (CRD) with treatment doses of mycorrhizal fertilizer, namely 0 g, 5 g, 10 g, and 15 g per polybag. The amount of Pb applied to the planting media is 5 ppm per polybag. The highest Pb accumulation was found in spinach plants treated with 5 g of mycorrhizal fertilizer. The average accumulation of Pb in roots, stems and leaves in this treatment was 103.57 ppm; 36.67 ppm; and 8.60 ppm. The growth of spinach plants in the 5 g mycorrhizal fertilizer treatment was better than the other treatments, namely having the highest average plant height and number of leaves in the 4th week (9.7-12.5 cm and 6.9-8.6 pieces). Application of mycorrhizal fertilizer can increase Pb accumulation in roots, stems and leaves and increase the growth of spinach plants at a dose of 5 g per polybag.
