Abstract

This study aims to determine the implementation of production technology and the potential of shallot cultivation of sub optimal land in the off season. The research was conducted in Sanden, Bantul from March to May 2017. This research used survey method. The sampling stage is the selection of villages and farmer groups conducted purposively. The number of samples is determined proportionally, while the sample determination is done by snowball sampling technique with 30 persons. The observation parameters of shallot yields were: diameter of tube, weight of tube, rotten / porous tube and weight shrinkage after being stored for 3 months. The data has been collected by descriptive analysis in tabulation form. The results showed that the technology used in the cultivation of shallots in the off season is not different from the in season. The varieties developed are biru, bima and tiron with 20 x 20 cm spacing, organic and inorganic fertilizer use. Implementation of technology in the off season roduces a product of 7,60 kwintal / hectare and lower than in the in season of 92,51 quintals/hectare. Characteristics of off-season shallot were: diameter 20,5 mm; Weight per tube 2,8 grams; Tubers porous / rotten very low (0%) and shrinkage store 25,25%. The result of shallot in the off season has the potential to be developed into seeds.

Abstract

This research were aimed 1) to study the effected phonska dosage to growth and yield of shallot in rainy season, 2) to study the effected varieties to growth and yield of shallot in rainy season. The research was implemented at Berbah, Sleman for February April 2015. The research used design of split-plots by 3 replication. The main plot was phonska doses (P) i.e P1= 100 kg/ha, P2= 200 kg/ha, P3= 300 kg/ha dan P4 = 400 kg/ha. The sub plot were varieties (V) i.e V1 = Bima, V2 = Tiron, V3 = Crok Kuning. Observation was conducted to plant height, leaves number, fresh weight per cluster, dry weight per cluster, Stover weight per hectare, fresh bulb weight per hectare, dry bulb weight per hectare, bulb diameter and harvest index. The data obtained was analysed by variance analysis with 5% level of significance. The results of research showed that didn't interaction to phonska dosage and varieties to all parameters. The increasing phonska dosage didn't affected significantly to all growth and yield of shallot. Varieties affected significantly to growth and yield the shallot. The highest productivity in rainy season was Tiron varieties i e. fresh bulb weight per hectare (107,1 kw/ha) dan dry bulb weight per hectare (96,7 kw/ha).

Abstract

This study aimed to design development commodities the shallot in an effort to improve its productivity and stability. Research carried out on August October 2009, in Bantul District. Data analysis methods used Magic Box Methods. The principle of the magic box by using the parameters of the productivity and stability. Productivity data of shallot which used the rayon in 2004 2008. The results showed the productivity (PR) of shallot in Bantul District, categorized as low if the productivity of <76,7 kw / ha, moderate (76,7 ≤ PR<127,86 kw / ha) and high if the PR ≥ 127,8 kw/ha. Stability categorized low if the value CV> 20%, moderate (10-20%) and high if <10%. Results of analysis showed that the magic box at Sanden Rayon has the same stability and productivity, ie productivity of medium and high stability (Box 4. The rayon of Srandakan, Kretek, Pundong and Pandak has productivity and stability are being (Box 5). The Rayon of Imogiri and Bambanglipuro has productivity of medium and low stability (Box 6). Based on the analysis of a magic box, empowerment is done through two approaches according to the resulting box. In general empowerment activities with research and extension. Empowerment of Box 4 include: 1) the increased of land fertilizer 2). the use of variety. Empowerment of box 5 and 6 include : 1) the increased of land fertilizer 2). the use of variety and 3) manajeman of cultivation.

Abstract

This research was aimed to study of effects of anorganic.fertilizer to seed bulb quality of shallots at coastal sandy land. The research was conducted with completelly block randomized design, which consists of two factors. The first factor was Urea+ZA level : 1/3, 2/3 and 1 dosages. The seconds factor was phosphor+potassium level : 1/3, 2/3 and 1 dosages. The fertiltzer recomendation were Urea of 150 kg.ha-1, ZA of 250 kg.ha-1, TSP and KCL of 15A kg.ha-1. To control was used land no fertilizer. The observation of parameters were bulb diameter, bulb hight, bulb color, bulb particle weight, solubility, total, content of N, P and K. The data were analysis by variances and orthogonal contras 5%. The results showed the usage anorganic fertilizer at coastal sandy land increased seed bulb quality of shallots. The increasing Urea+ZA and phospor+potassium level did not significant on seed bulb quaiity of shallot.

The first factor was nitrogen (N) proportions: l/3, 2/3 and dosages. The second factor was phosphor*potassium proportions: I/3, 2/3 and t dosages. The fertilizer recommendation were 250 kg.ha-1 Urea, 150 kg.ha-1 ZA, TSP and KCL. For comparison purposes; the control plot did not use any fertilizer. The parameters of observation were bulb total, the fresh and dry weight, harvest index and bulb diameter. The data were analyzed by variances and orthogonal contrast 5%. The results showed that there was no significant interaction between nitrogen and phosphor + potassium, level, except bulb total and harvest index. The application of nitrogen and phosphor + potassium was not significant on the yield of fresh bulb, dry bulb and bulb diameter.

Abstract

Utilization of basalt scoria stone as one of the building materials that can be one of thealternatives to limestone which has been known as a cement maker and utilizes the availability ofabundant basalt, especially in Lampung which has these natural resources. This research is toanalyze the basalt stone powder and analyze the optimum content at the temperature variation ofthe most effective mixture of basalt stone powder to produce compressive strength of concrete.The research method uses experimental methods at the Bandar Lampung University laboratory.The specimens used were cylinders with a diameter of 10.16 cm and a height of 20cm totaling 63specimens using the DOE method. There are 6 types of mixtures, namely at a temperature of800˚C there are 2 mixes of 3% and 7% basalt stone powder, a temperature of 1200˚C there are 2mixes of 3% and 7% basalt stone powder, and at a temperature of 1600˚C there are 2 mixtures of3% and 7% basalt stone powder. Compressive strength testing is performed at the age of concretetesting 7, 14, and 28 days.The results of the study show that the addition of heated basalt stone powder can increase thecompressive strength of concrete. The compressive strength results in a mixture of temperaturevariations included in the planned compressive strength. The optimum compressive strength valueof 28 days of testing occurred on 3% concrete mix of basalt stone powder at a temperature of1600˚C that is equal to 392 kg / cm².Keywords: Concrete, Basalt Stone and compressive strength
