Protein and Anthocyanin Production of Waterleaf Shoots (Talinum Triangulare (Jacq.) Willd) at Different Levels of Nitrogen+Potassium and Harvest Intervals

The experiment was conducted at IPB Experimental Station, Leuwikopo, Dramaga, Bogor, from November 2009 untilFebruary 2010 to study the effect of different nitrogen+potassium rates and harvest intervals on protein and anthocyaninproduction of waterleaf shoot (Talinum triangulare (Jacq.) Willd). A randomized complete block design was used with threereplications of two factors, which were four N+K dosages (50 kg urea + 50 kg ha-1 KCl, 50 kg urea + 100 kg ha-1 KCl, 100 kgurea + 50 kg ha-1 KCl, 100 kg urea + 100 kg ha-1 KCl) and three harvest intervals (30, 15, and 10 days). The results showedthat interaction of 100 kg urea + 100 kg ha-1 KCl and 15-day harvest interval produced the highest content (8.29 mg g-1 freshweight) and production (4.72 g plant-1) of protein. The interaction of N+K dosages and harvest intervals were not signifi cantin affecting the anthocyanin content. The highest production of anthocyanin was produced by single treatment of 100 kg urea+ 100 kg ha-1 KCl (152.23 μmol plant-1) and 10 days harvest interval (165.47 μmol plant-1), respectively. Leaf protein levelsnegatively correlated with anthocyanin content

Pengendalian Hama Ulat Menggunakan Larutan Daun Pepaya dalam Peningkatan Produksi Sawi (Brassica Juncea L.)

This research was conducted from March to May 2016 at Bina Putra Garden, Guntung Payung, Landasan UlinDistrict, Banjarbaru. The Purpose of study to determine the effect of papaya leaf solution and the better concentration to against leaf-eating caterpillars pests and to promoted mustard production. The experimental design used a randomized block design one way with four of solution of papaya leaf percentage treatments (0, 40, 70 and 100). All treatments were made in the formulation 100 ml of solution. Study results showed that papaya leaf solution concentration of 100% is capable to control leaf- eating caterpillar pets and production of mustard

Pengaruh Pemberian Pupuk Hayati Dan Mikoriza Terhadap Intensitas Serangan Penyakit Layu Bakteri (Ralstonia Solanacearum), Pertumbuhan, Dan Hasil Tanaman Tomat

The research about the effect of applications biofertilizer and mycorhiza to intensity attack of bacterial wilt disease, growth, and yield of tomato was conducted in trial garden of Agriculture Faculty Lambung Mangkurat University from November 2015 until February 2016. The experiment was arranged in a completely randomized design with one factor, four treatments (no treatment (control), biofertilizer, mycorhiza, and biofertilizer + mycorhiza), and five replications. The results of experiment were compared to control showed that the applications of biofertilizer + mycorhiza could reduce intensity attack of bacterial wilt disease by 29.20%, flowering time was 10 days faster , and fresh weight of fruit was 122 g heavier. The increasing of plant height and stem number did not affected by all treatments

Produksi Biomassa dan Bahan Bioaktif Kolesom (Talinum Triangulare (Jacq.) Willd) dari Berbagai Asal Bibit dan Dosis Pupuk Kandang Ayam

Field experiment to study biomass and bioactive compound productions of Talinum triangulare from different propagules and chicken manure dosages was conducted at Leuwikopo, Dramaga, Bogor, West Java, Indonesia from September to November 2005. The research used split plot design with 3 replications. The main plot was propagules (seed and stem cutting) and sub plot was chicken manure dosages (0, 5, 10, and 15 t ha-1). Bioactive compound was determined qualitatively. The results showed that stem cutting gave the highest leaf dry weight (7.78 g plant-1) and tuber dry weight (4.99 g plant-1). The bioactive compounds (alkaloid, steroid, saponin, tannin, and flavonoid) were not influenced by propagules. The dosage of 15 t ha-1 chicken manure gave the highest leaf dry weight (10.73 g plant-1) and tuber dry weight (6.36 g plant-1). The bioactive compound decreased with the increasing chicken manure dosages. Interaction of stem cutting and 15 t ha-1 of chicken manure gave the highest leaf dry weight (12.43 g plant-1). Bioactive compound and tuber dry weight were not influenced by the interaction of propagules and chicken manure dosages

Substitusi Pupuk Npk Dengan Bokashi Eceng Gondok (Eichhornia Crassipes) Pada Pembibitan Tanaman Lada

This study aims to obtain the right composition in the use of water hyacinth bokashi that can substitute inorganic fertilizer in pepper plants. This research was carried out using polybag at plantation CV location. Gunung Putri Martapura for 4 months from January to May 2018 with experimental design of Randomized Non-Factorial Complete (RAL) with 5 treatment of plant media composition, namely: p0 = soil + 100% NPK “Mutiara” (without water hyacinth bokashi); p1 = soil: water hyacinth bokashi (3: 1 / v: v) + 75% NPK “Mutiara”; p2 = soil: water hyacinth bokashi (2: 2 / v: v) + 50% NPK “Mutiara”; p3 = soil: water hyacinth bokashi (1: 3 / v: v) + 25% NPK “Mutiara”; p4 = soil: water hyacinth bokashi (1: 3 / v: v) (without NPK “Mutiara”). Each treatment was repeated 4 times so that the entire plot of the experiment was 20 plots. Each plot consists of 5 plants so that there are 100 plants in total. Observations were made on plant height, stem diameter, the number of leaves, length of the segment, sprout age, and dry weight of the plant. Based on the result of the research, the treatment of various plant media composition has no significant effect on plant height, stem base diameter, leaf number, and dry weight of plant, but significantly affect the age of sprout and length of pepper plant so it can be concluded that water hyacinth bokashi in early the growth of pepper plants cannot substitute inorganic fertilizers but can be complimentary of inorganic fertilizers. The best cultivation plant composition treatment on pepper seedling in this study was on soil composition: water hyacinth bokashi (3: 1, v: v) + 75% NPK “Mutiara” and on soil composition: water hyacinth bokashi (2:2; v: v) + 50% NPK “Mutiara”
