Abstract

Marlina et al. 2012. The Response of Rice (Oryza sativa L.) to Organic Fertilizer Plus and Organic Pesticides under the System of Rice Intensification (SRI) in Tidal Lowlands. JLSO 1(2):138-148. This study aims at evaluating the response of rice (Oryza sativa L.) to the dosage and type of organic fertilizer plus and organic pesticides under the System of Rice Intensification (SRI) in tidal lowlands. This research was implemented at the rice field Desa Tanjung Sari, Kecamatan Tanjung Lago, Kota Terpadu Mandiri  (KTM) Telang, Kabupaten Banyuasin. The research was conducted from December 2010 until March 2011. It employedFactorial Group Randomized Design (RAK) to allow each factor were repeated 3 times for 5 plant samples. Variability analysis indicates that the provision of the dosage of organic fertilizer plus provided significant  effect on plant height, the number of seedlings, the number of productive seedlings, grain per panicle, production, and the percentage of infestation. However, it did not show significant  effect on the percentage of empty grains. The provision of organic pesticides provided significant effect on grain per panicle, production, the percentage of pests, but gave no effect on plant height, the number of seedlings, the number of productive seedlings, and the percentage of empty grains. The combination of powdered organic fertilizer plus of  750 kg / ha and  organic pesticides (animal and vegetable pesticides) gave  the highest production of 2.23 kg/plot or 5.57 ton/ha.

Abstract

Marlina et al, 2018. Utilization of Various Types of Biofertilizer on the Production of Shallots (Allium ascalonicum L.) in overflow type C Tidal Soils from Banyuurip. JLSO 7(1):74-79. Tidal land has considerable potential to be used as agricultural land, one of which is for shallot, but the obstacles faced in this tidal land are high soil acidity and low soil fertility. Therefore, to increase the production of onion plants can be given biological organic fertilizer. This study aimed to analyze the right type of biological organic fertilizer in increasing the production of shallots. This research was carried out at the Greenhouse in Palembang. The design used was Factorial Randomized Completely Block Design with consisted of 4 treatment factors with 6 replications for each treatment.  The first factor was control (O0), the second factor was biofertilizer enriched with Azospirillum (O1) bacteria, the third factor was biofertilizer enriched with phosphate solvent bacteria (BPF) (O2), and the fourth factor was biofertilizers enriched with Azospirillum and BPF bacteria. The results showed that the treatment of Azospirillum and BPF-enriched biofertilizers gave the best production per hill of onion by 85.33 g.

Abstract

Syafrullahet al, 2018. Rehabilitation of Pit after Tin Mining by Floating Agricultural Technology at Red Curly Lettuce Cultivation in the Bangka Belitung Province. JLSO 7(1):88-96. Bangka Belitung Province is the largest tin producer in Indonesia. After tin mining was formed pit/under the surface of the earth . This pit potential was quite large, especially under the colonies near the settlement, in addition to fishery business could also be used with floating plant cultivation. The purpose of this research was to get location-specific cultivation technology of location specific plant at pit after tin mining which was floating plant cultivation technology and utilize the pit after  tin mining to be productive pit for cultivation of vegetable crops and preserve the environment by utilizing the pit, plastic waste and grass became useful in the cultivation of floating vegetable crops at the pit after tin mining. This research was conducted from January to May 2016 in Batu Belubang Village, Pangkalan Baru District, Central Bangka Regency of Bangka Belitung Province. The design used was Factor Randomized Random Design (RAK) with 9 treatment combinations repeated 3 times and 5 sample plants. As the indicator plant was  red curly lettuce. The treatments were 1) Type of raft  (R) with 3 levels,those are R1 = raft of plastic waste size of  250 ml, R2 = raft of plastic waste size of  600 ml, R3 =  raft of plastic waste size of  1500 ml and 2) compost type (X) with 3 levels ,namely K1= compost of purun  grass K2 = compost of bakung grass and K3 =  compost of gegas grass. From the results of the research showed that the type of  plastic waste raft size of 250 ml and type of bakung grass compost gave the better growth and production response for curly red lettuce and the application of technology cultivation of curly floating red lettuce plants at the pit after  tin mining lead to give the same results and tend to higher if compared with the system of cultivation coventionally on the dry land.
