Abstract

Nitrification inhibitors are used to decrease the rate of nitrification process so it can decreases the nitrate losses. The objective of this study was to investigate the improvement of urea effectiveness by using urease and nitrification inhibitors on shallot. The study was conducted at Blubuk Village, Tanjung, Brebes District, Central Java, Indonesia from December 2017 to April 2018. The experiment was arranged in a randomized block design with 8 treatments and 3 replications. The treatments were untreated group (P0), 100% dose of Urea without inhibitor (control) (P1), (3) 100% dose of Urea + Urease Inhibitor (P2), 100% dose of Urea + Nitrification Inhibitor (P3), 100% dose of Urea + Urease Inhibitor + Nitrification Inhibitor (P4), 80% dose of Urea + Urease Inhibitor (P5), 80% dose of Urea + Nitrification Inhibitor (P6), and 80% dose of Urea + Urease Inhibitor + Nitrification Inhibitor (P7). The results showed that 100% dose of Urea + Urease inhibitor, 80% dose of Urea + Urease inhibitor, 80% dose of Urea + Nitrification inhibitor, and 80% dose of Urea + Urease inhibitor + Nitrification inhibitor treatments significantly produced higher plants heights, number of leaves, and more number of tillers compared to control treatment (100% Urea without inhibitors), without affecting the yield and yield components.

Abstract

Excessive use of inorganic fertilizers mainly NPK causes soil degradation, environment pollution, decreases production, and reduces soil biological activity. System of rice intensification is one method of rice cultivation. SRI main principles are seed transplanting at young age (7-11 days old), transplanting use single seedling methode, seedlings at wide plant spacing ? 25x25 cm, intermittent irrigation and field conditions are not flooded, and reduction of chemical fertilizers and application of organic fertilizer. This research was conducted at Situgede Village, West Bogor District, Bogor. The research design was split plot randomized complete block design with three blocks. Two rice cultivation system as the main plot and five combinations of fertilizer application as sub plot. In the main plot consisted of two rice cultivation which is conventional and SRI while the subplot consisted of five combinations of fertilizer application is no fertilition, 100% inorganic fertilizers (Urea = 250 kg ha-1, SP-36 = 75 kg ha-1 and KCl = 50 kg ha-1), 75% inorganic fertilizers (Urea = 187 kg ha-1, SP-36 = 56.8 kg ha-1 and KCl = 37.5 kg ha-1) + 200 kg of bio-organicfertilizer, 50% inorganic fertilizers (Urea = 125 kg ha-1, SP-36 = 37.5 kg ha-1 and KCl = 25 kg ha-1) + 200 kg of bio-organicfertilizer and 50% inorganic fertilizers (Urea = 125 kg ha-1, SP-36 = 37.5 kg ha-1 and KCl = 25 kg ha-1). The results showed that SRI method produced maximum number of tillers higher that of 25.8 tillers/hill or an increase of 64.33% compared with conventional methods. Wet and dry shoot weight of wet and dry weight of root is greater in successive SRI method of 13.3%, 19.1%, 1.40% and 41.8% compared with the conventional method. The number of productive tillers, grain number/panicle, 1000 grains weight, root wet weight and dry grain at SRI method was higher than those in conventional method respectively 58.6%, 37.0%, 2.50%, 25.1% and 32.6%. The uptake of N and P in the SRI method higher at 72.0% and 100% compared to conventional method.

Abstract

The data from the Health Research Association of Indonesian Ministry of Health in 2010 showed approximately 35.6% infants having PEM. The diet therapy for severe PEM is modisco. However, due to protein deficiency such as a protease enzyme resulting in nutrients malabsorption, modisco has not been able to compensate the lack of protein in PEM. It requires an active substance to increase protein absorption by adding a proteolytic enzyme. One of the source of proteolytic enzyme is pineapple. The study aimed to prove that addition of pineapple extract on modisco can increase levels of albumin and hemoglobin in severe PEM rats. This was a true experimental study with pre-post test control group design. The sample were 25 male Wistar rats aged 2 months. The data analysis using the Pairwise T test, one way ANOVA followed by LSD showed a significantly difference between pre and post test for both albumin and haemoglobin. The pineapple extract at a dose of 9 and 11 mg/day increased albumin level. And the dose of 7, 9 and 11 mg/day pineapple extract increase haemoglobin level. In conclusion, a modisco modification using pineapple extract for nutritive therapy increased both albumin and hemoglobin levels on severe MEP rats.   Keywords: Severe PEM, Modisco, Pineapple extract

Abstract

Enzim selulase terdiri dari tiga enzim ekstraselular yang bekerja secara sinergis dalam mendegredasi selulosa, yakni endoglukanase, eksoglukanase dan ?-glukosidase. Tiga enzim tersebut berperan dalam mendegradasi selulosa menjadi gula sederhana. Penelitian ini bertujuan untuk mengisolasi dan menyeleksi mikroba (bakteri dan fungi) berdasarkan aktivitas enzim selulase dari mikroba tanah yang diisolasi dari persawahan pasang surut Kalimantan Selatan. Kemampuan mengekskresikan enzim endoglukanase dinilai berdasarkan nilai indeks selulolitik pada media CMC dan kemampuan mengekskresikan enzim eksoglukanase dan ?-glukosidase diukur dari aktivitas kedua enzim tersebut menggunakan metode Mandel yang dimodifikasi. Hasil yang diperoleh menunjukkan bahwa kisaran nilai indeks selulolitik dari mikroba selulolitik di persawahan pasang surut tipe A sebesar 2.29-3.72, di lahan tipe B sebesar 2.66-5.41, dan di lahan tipe C sebesar 1.84-3.34. Aktivitas eksoglukanase dari mikroba selulolitik di persawahan pasang surut tipe A sebesar 0.27-1.65 nkat mL-1, lahan tipe B sebesar 0.37-1.85 nkat mL-1, dan lahan tipe C sebesar 0.31-1.85 nkat mL-1. Mikroba selulolitik dari persawahan pasang surut Kalimantan Selatan memiliki aktivitas ?-glukosidase sebesar 0.05-1.52 nkat mL-1. Isolat- isolat mikroba selulolitik yang memiliki aktivitas selulase tertinggi adalah isolat bakteri selulolitik J11, J42, R23, BK12, C52, TB41, B82 dan SN123, dan isolat fungi selulolitik ST33, ST22, TB31, B52, GA22, TD11, PI52 dan P31.

Abstract

Diabetes melitus adalah penyakit metabolik dengan karakteristik hiperglikemia yang terjadi karena kelainan sekresi insulin, kerja insulin, atau keduanya. Hiperglikemia menjadi faktor penentu dalam perkembangan disfungsi endotel dan penurunan kemampuan pembentukan pembuluh darah baru. Proses pembentukan pembuluh darah baru dihasilkan dari proliferasi endotel setempat dan peran dari Endhotelial Progenitor Cell (EPC) yang dapat dicegah dengan pemberian antioksidan. Salah satu tanaman yang mengandung antioksidan adalah ubi jalar ungu. Dalam penelitian ini, 25 ekor tikus dibagi menjadi 5 kelompok, yaitu 2 kelompok kontrol dan 3 kelompok perlakuan. Pemberian ekstrak dilakukan selama 14 hari melalui cara sonde dengan dosis 1,4 cc/ekor/hari, 3,5 cc/ekor/hari dan 5,6 cc/ekor/hari untuk P1, P2 dan P3. Penghitungan jumlah EPC tikus dilakukan dengan flowcytometry, selanjutnya data dianalisis dengan analisis Oneway ANOVA. Meskipun tidak berbeda secara signifikan, jumlah EPC pada tikus yang diinduksi ekstrak ubi jalar ungu lebih tinggi dibandingkan dengan kelompok tikus diabetik tanpa perlakuan). Dapat disimpulkan bahwa pemberian ekstrak air ubi jalar ungu dengan berbagai dosis tidak menunjukkan adanya perbedaan nyata terhadap kadar EPC tikus yang diinduksi diabetes mellitus.   Kata Kunci: Antioksidan, Diabetes melitus, EPC, Ubi Jalar Ungu
