Abstract

This study aims The Number of Seeds and Pruning of Maize Yields (Zea mayz L). The research was conducted in April to December in the village of Pandes, Wedi Subdistrict, Klaten Regency, Central Java Province. High land 115 m type soil Vertosol. This research used a completely random factorial 2 x 4 randomized Block design. The First factor is the number of corn seeds per planting hole (B), consisting of 2 levels B1: 1 seed per planting hole with a spasing (column) of 20 cm, B2: 2 seeds per planting hole white a inter spasing (row) 40 cm. The second factor is pruning (P), consisting of 4 levels: P0 white out pruning (control), P1 pruning leaves under the corn cob, P3 pruning male lowers (tassel) and P4 in combination. Results, all treatment parameter had no interaction, except the weight of corn seeds per cob. All treatment parameter was not significantly different except the weight of corn kernels per corn cob. The largest seed weight is the combination of B1P2 (183,93 grams per corn cob, number of seeds 1 grain planting hole with pruning of leaves and male lowers. The smallest seed weight is the combination of B1P0 (176,88 grams per corn cob, number of seeds 1 grain planting hole without pruning.

Abstract

The study aims to determine the concentration of Trichoderma sp. effective for controlling Fusarium oxysporum wilt in chilli plants, which was carried out in Banguntapan Village, Banguntapan District, Bantul District, from March to October 2018. The study used a complete randomized block design consisting of 5 treatments of Trichoderma sp. ie 0.0 g, 2.50 g, 5.0 g, 7.50 g and 10.0 g biomass / m2 with 4 replications each treatment. Application was carried out by isolating the biomass of Trichoderma sp. inoculated in 2.5 kg of organic fertilizer / compost, then sprinkled on the ield before chilli seedlings were planted. Based on the analysis of the incubation period and the intensity of the attacks, showed that the treatment of Trichoderma sp. with a concentration of 10.0 g of biomass gave effective results and reduced the intensity of Fusarium oxysporum wilt attack by 12.15 percent.

Abstract

Tamanmartani is a government program that is the integrated crop planting movement (GP-PTT) program in the year 2015. One of the components is rice planting with Legowo and planting system. But farmers until now still apply loor tile system. That the impact on the average productivity in Tamanmartani Village 5 last year only reached 5 ton/ha, from the year 2014-2018. This study was conducted from January to July 2019, in Tamanmartani Village, Kalasan District, Sleman Regency. The method used is descriptive, data collection using interviews, questionnaires, and observations using a Likert scale with precise, less precise, and incorrect categories. Respondents were determined by Proportionate Random Sampling as many as 39 farmers who participated in the program (GP-PTT). Results showed that the analysis of the perception of farmers from 4 variables on knowledge, interests, attitudes, and needs, turns out the lowest variable with a percentage of 67.09 that is the attitude variable, with the lower statement The Implementation of Tajarwo System with a percentage of 58.97%. This means that the attitude of farmers has a negative effect on farmers perception of technology in the Legowo farming system.

Abstract

Biological agents as one of the alternatives that are environmentally friendly control and in accordance with the guidelines of IPM is still not implemented. The purpose of this study to determine the interaction of dose and concentration of biological agents on the growth and yield of onion as well as to the intensity of the disease on onion crop, effect of the use of biological agents Trichoderma sp on growth, onion, and diseases of the onion crop, the concentration of PGPR right for growth and onion as well as against diseases of the onion crop. Fieldwork was arranged in a randomized block design Complete (RAKL) two factors, one control and three replications. The irst factor is the dose of Trichoderma harsianum (T) consists of two levels ie: T0: Without Trichoderma harsianum L, T1: Trichoderma harsianum L. dose of 50 kg / ha (5 mg / m2). The second factor is the concentration of PGPR (P) consists of 4 levels: P0: Without PGPR, P1: PGPR concentration of 2%, Q2: PGPR concentration of 4%, P3: PGPR concentration of 6%. The results showed no interaction between dose and concentration on the intensity of fusarium wilt, growth variables dry weight per hill, tuber crops variable dry weight per hectare. The highest efficacy for controlling diseases in onion combination treatment without the use of Trichoderma sp and PGPR concentration of 0%. PGPR concentration of 6% gave the highest yield of the dry weight of tuber crop yield of 12.7 tonnes per hectare.

Abstract

Cassava rengginang, a Javanese traditional snack food still shows cloudy white colour and no or very slight expansion when fried that are considered as a problem of undesired quality. Additional fermentation process in its manufacturing seems to be able to solve the problem. Fermentation process applied to the cassava rengginang manufacturing will affect its quality, especially the crispness, expansion capacity and taste. The crispness would possibly bring about irritation to both the throat and tongue in a little bit longer and more consumption. Two factors possibly influencing the above problem are frequency of washing process and total amount of starch resulted from every washing process, are taken as treatments. Organoleptic evaluation involving tests on texture, aroma, taste, crispness and levels of consumer preferences is taken as a variable response. The experimental design consisting of once, twice, three times and without washing process and total amount of starch related to the frequencies of the washing process was conducted to seek the best combination of the treatments that was automatically resulting in the highest variable response. Investigation tests, conducted on the fried non fermented cassava rengginang, show that the combination of three time washing process related to 244.38 grams cassava starch, 30.50 gram residue with 3 litters of water is significantly the best and preferred more than that of currently available in local markets.
