Natrium Tetraborate (boraks) merupakan jenis bahan tambahan makanan (BTM) berfungsi sebagai sebagai pengawet  yang dilarang Kementerian Kesehatan RI No 235/Menkes/VI/1984. Konsumsi makanan yang mengandung boraks dapat  menyebabkan gangguan otak, hati, lemak, ginjal, demam, anuria, koma, bahkan kematian. Analisa kualitatif boraks kini mulai dikembangkan memanfaatkan bahan-bahan alam, salah satunya ubi ungu. Ekstrak Ubi Ungu dapat digunakan sebagai pendeteksi boraks karena ekstrak Ubi Ungu mengandung senyawa antosianin. antosianin dapat mendeteksi adanya kandungan boraks pada makanan akan tetapi sering terjadi positif palsu pada uji. Penelitian ini dilakukan di Kesehatan Pengujian Kalibrasi dan Penunjang Medis Provinsi Nusa Tenggara Barat dengan tujuan untuk mengetahui BTM yang menyebabkan munculnya positif palsu deteksi borak. Berdasarkan hasil penelitian yang telah dilakukan dapat disimpulkan bahwa Bahan tambahan makanan dengan hasil positif palsu pada uji kualitatif boraks dengan filtrat ubi ungu (Ipomoea Batatas L) yaitu Natrium Benzoat, Monosodium Glutamat, Natrium Tripoliposfat, Natrium Bikarbonat, Bikarbonat, Natrium Karbonat, Natrium Polipospat, dan Carboxyl Methyl Cellulose

Human’s increasing activity causes an immense increase in domestic waste. one form of domestic waste which could harm environment is vegetable waste. in this research, vegetables waste is used as based material of liquid compost. The process of producing liquid compost with vegetables waste as the base materials was using EM4 fermentation method as a starter and zeolite 80-100  mesh as the bind for soil nutrient in liquid compost. In the fermentation process, the researcher conducted 3 different behaviors in adding EM4 and Zeolite, in each 10 gr, 20 gr and 30 gr of EM4; and 40 gr, 60 gr and 80 gr of Zeolite. The fermentation process was conducted  in 40 days. The liquid compost samples were analized for pH, C-Organic, N-total, P-total and K-total. The results showed that highest concentrate of soil nutrient was from the adding of 30 gr EM4 and 80 gr Zeolite in which the result was 0.27% C- organik, 0,07 %  N-total, 0,04 % , P-Total dan 0,46 %  K-Total.

This research aims to know the diversity of mangrove in Gedangan Village, Purwodadi Subdistrict, Purworejo Regency, Central Java. This research conducted on June-September 2016 with purposive sampling methods with three station. Based on the results of the research are nine mangrove species found are rhizophora mucronata, sonneratia alba, nypa fruticans, hibiscus tiliaceus, ipomoea pescaprae, acanthus ilicifolius, gymnanthera paludosa, wedelia biflora, and scirpus sp. Diversity of tree mangrove are low (H’ station 2=0,95 and H’ station 3= 0,15). Diversity of sapling mangrove are low with H’ in station 1, 2, and 3 are 0,2; 0,68; dan 0,08. And the diversity of mangrove seedling and lower plants are medium with H’ in station 1, 2, and 3 are 1,17; 1,56; and 1,48. Environment condition in all station is relatively good to support the life of mangrove plant. That is temperature  28-30 0C; pH 7-8; DO 4,0-6,5 mg/l; salinity 6-9 ppt; and sandy mud substrate.

Abstract. Indonesia has abundant biodiversity, including ants (Formicidae). This study aims to determine the genus of Formicidae members in the garden of Al- Azhar Islamic University (Unizar), Mataram, West Nusa Tenggara. The research was conducted by using the exploration method. Based on the research, there are 4 (four) genera of Formicidae members in the Al-Azhar Islamic University (Uniar) Park, Mataram, West Nusa Tenggara, namely: Anoplolepis, Paratrechina, Odontoponera, and Lophomyrmex.Keywords: Formicidae, characteristics, Al-Azhar Islamic University

Abstract. This research is a type of experimental research carried out in a laboratory with the aim of knowing a symptom or effect that arises as a result of certain treatments. The research was conducted at the Immunobiology Laboratory, Faculty of Mathematics and Natural Sciences, Mataram University. The material used in the study was 1 male Bali cow, about 3.5 years old with a cow weight of 460 kg, which the semen was collected using an artificial vagina. The experimental design used in this study was a completely randomized design which was arranged in a factorial design consisting of 3 (three) factors. The first factor is the difference in layer (L) which consists of 2 (two) levels, namely the Upper Layer (LA) and the Lower Layer (LB). The second factor is the concentration of tomato lycopene (P) consisting of 5 (five) levels, namely: 0% (P0), 5% (P1), 10% (P2), 15% (P3) and 20% (P4). The third factor is storage time (H) which consists of 6 (six factors), namely 1 day (H1), 2 days (H2), 3 days (H3), 4 days (H4), 5 days (H5) and 6 days. (H6). The three factors combined to produce 60 treatment combinations, each treatment combination was repeated 6 (six) times so that there were 360 experimental units. The results of the analysis of variance showed that the addition of the tomato fruit lycopene antioxidant and the separation by the swim up method had no significant effect (P> 0.05) on the normality and abnormality of spermatozoa. The addition of tomato fruit lycopene antioxidants and the separation using the swim up method did not have an effect on increasing spermatozoa abnormalities, but did not have a negative effect on the spermatozoa of bali cattle.Keywords: antioxidant, tomato fruit, spermatozoa, bali cow
