Abstract

The aims of this research is to get the best concentration of cow urine as liquid organic fertilizer on rubber seed growth, to get the best fermentation time for cow urine as liquid organic fertilizer on the growth of rubber seedlings, and get the best interaction between concentration and cow urine fermentation as liquid organic fertilizer on the growth of rubber seedlings. The experiment was conducted in teaching farm of State Polytechnic of Lampung from January 2016 until June 2016. The treatments arranged in Randomized Block Design (RBD) with the factorial pattern consisting of two factors. The first factor was the concentration of cow urine, consisting of four levels: 15 cc.l-1, 30 cc.l-1, 45 cc.l-1 and 60 cc.l-1. The second factor was the duration of cow urine fermentation, consisting of five levels: 0 day, 7 day, 14 day, 21 day and 28 day. Rubber seedlings were used as plant indicator. Observations included plant height, number of petiole, stem diameter, stem girth, and dry weight of biomass. The results showed that the treatment of cow urine concentration had significant effect on plant height and number of petiole, but very significant effect on stem diameter, stem girth and dry weight of biomass. Likewise, the treatment of cow urine fermentation has significant effect on all observed variables except on the dry weight of biomass has a very significant effect. The interaction between treatment of cow urine concentration and cow urine fermentation did not significantly affect all variables except on dry weight of biomass had significant effect, i.e. cow urine concentration treatment of 45 cc.l-1 and fermentation of cow urine for 28 days resulted in dry weight of biomass higher rubber seedlings.   Keywords: cow urine, fermentation, rubber seedlingsPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/651

Abstract

Cocoa (Theobroma cacao L.) is one of the estate crop commodities that is currently being developed because the cocoa plant is one of the export commodities that produce a lot of foreign exchange and has a role as high value sector besides oil and gas. Cocoa farming can increase the income of cocoa farmers, create and expand employment. This experiment used Randomized Block Design (RBD) which consisted of 4 treatments that was repeated 6 times (control, 1 tablet.polybag-1, 2 tablet.polybag-1, 3 tablet.polybag-1). This study was conducted to determine the best rate of compound fertilizer tablets for cocoa seedlings growth. The data obtained were analyzed by analysis of variance at 95% accuracy level. The results showed that there was a compound effect on the growth of cocoa seedlings to the variable of seed height, stem diameter, leaf number, leaf area, dry root weight, and total dry weight of stalk. Application of tablet compound fertilizer 1 tablet.polybag-1 gives the best results on the growth of cocoa seedlings.     Keywords: cocoa seedlings growth, inorganic fertilizer, tablet compound fertilizerPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/647

Abstract

Armyworm (Spodoptera litura F.) as a polyfagous insect is a key pest of either food crops or estate crops. The larva often attack leaves of beans, cereal, shallot, cabbage, cotton, tobacco, and sugarcane. Synthetic insecticides are usually used 2 – 3 times a week in order to manage this insect. The use of synthetic insecticides need high cost, have negative impacts such as insect resistance and resurgence, killing non-target insects, residual effects on yield, and environmental contamination and pollution. Botanical insecticide has a highly potential to be used in IPM because of its characteristics (no residual effect, cheap, easy to get and easy to apply). Mahogany seeds contain alkaloid, saponin, and flavonoid that have good insecticide activity. Extract of mahogany seeds can be used as insecticide, anti-feedant, growth retardant, and fertile retardant. The effectivity of mahogany seed extracts is affected by storage time and its concentration. The results of the experiment are the extract of mahogany seeds can be stored up to 3 weeks, and the highest effective is reached by the concentration of 20%, followed by 10% - 15% concentration as moderately effective.   Keywords: botanical insecticides, extract, mahogany seedPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/652

Abstract

There are many benefits of sugarcane (Saccharum officinarum L.) as a sugar source to fulfil human staples food. The use of sugarcane bud chips is one of cultivation technology in order to achieve national sugar self-sufficiency program. Bagasse mulch kept soil moisture and increased organic matter in the soil thathas positive impact on sugarcne growth. The experiment was conducted in Teaching Farm of the State Polytechnic of Lampung, from November 2015 until April 2016. The experiment used Randomized Block Design (RBD) in factorial pattern, consisting of two factors. The first factor is the treatment of bud chips position consisting of 3 levels i.e. top bud chip, middle bud chip, and bottom bud chips. The second factor is the bagasse mulch treatment consisting of 4 levels i.e. control, 3 ton.ha-1, 6 ton.ha-1, and 9 ton.ha-1. The objectives of the study were to obtain optimal growth among bud chips, optimal bagasse mulch, and to know the interaction between the bud chips position and the bagasse treatments. The results showed that the top bud chips were better than  middle bud chips and bottom bud chips. The optimal rate of bagasse mulch was 3 ton.ha-1. There was an interaction between the treatment of sugarcane bud chips and mulch bagasse on leaf length and soil moisture growth.   Keywords: bagasse mulch, bud chips, sugarcane seedlingsPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/648

Abstract

Gibberellin (GA3) is a natural growth hormone and synthesis used to break dormancy and accelerate germination and growth processes. The purpose of this study is to determine the effect of gibberellin concentration (GA3), soaking duration, and the interaction between gibberellin concentration (GA3) and soaking duration on the growth of australian pine tree seed. The research was conducted in State Polytechnic of Lampung from October 2015 to February 2016. This research used Factorial Randomized Block Design (RBD). The first factor is the concentration of gibberellin (GA3) namely A0 (without GA3), A1 (1000 mg.l-1 GA3), A2 (1250 mg.l-1 GA3), and A3 (1500 mg.l-1 GA3). The second factor is the soaking duration of GA3 namely B1 (soaking for 3 hours), B2 (soaking for 6 hours), and B3 (soaking for 9 hours). The result showed that GA3 at concentration 1500 mg.l-1 increased germination, the percentage of germinated seeds, hypocotyl diameter, hypocotyl length, growth homogenity, and vigor of australian pine tree seed. Soaking duration for 9 hours can increase germination, the percentage of germinated seeds, hypocotyl diameter, hypocotyl length, growth homogeneity, and australian pine tree seed vigor. The interaction between GA3 concentration at 1500 mg.l-1 and the soaking duration for 9 hours increased the germination, the percentage of germinated seeds, hypocotyl diameter, hypocotyl length, growth homogeneity, and australian pine tree seed vigor.   Keywords: Casuarina equisetifolia L., gibberelin, seed vigor, soaking durationPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/649

Abstract

In the sugarcane processing into sugar, it will produce g. About 52,9% of liquias, solid, and luquid waste. About 52,9% of liquid waste cause many problems. If the liquid waste directly discharged into the waters, it will cause pollution of water bodies, as well as air pollution around the river. The objective of this study is to obtain the effective and duration activity of the combination of active sludge and sodium bicarbonate in reducing the sugarcane industry of liquid waste. In this research, liquid waste management is done by aerobicized batch system stagnant in laboratory scale with the descriptive analysis. Biodegradation treatment is given to the liquid waste derived from anaerobic ponds in Bunga Mayang Sugar Mill, North Lampung. The treatment is L0 = without treatment (control), L1 = without sludge + 5 g.l-1 sodium bicarbonate, L2 = 100 ml.l-1 active sludge + 5 g.l-1 sodium bicarbonate. The result showed that application of 100 ml.l-1 active sludge + 5 g.l-1 sodium bicarbonate can increase the pH to 7,85, increase DO to 0,16 mg.l-1, reduce COD to 48,18%, increase sulfide content to 90,44%, increase turbidity to 95,4%, increase the wastewater temperature to 35oC, and the time required is shorter than the conventional anaerobic pools.   Keywords: active sludge, liqud waste, sodium bicarbonatePermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/650
