Abstract

The massive use of inorganic fertilizers without adequate organic fertilizers will cause land and plant productivity to decline. This study aims to obtain a combination of organic and inorganic fertilizers and their effect on rice production. The study used a Randomized Block Design with three replications and four treatments, namely a) full inorganic package (200 urea + 200 kg Phonska), b) organic fertilizer + 75% inorganic fertilizer, c) organic fertilizer + 50% inorganic fertilizer, d) organic + 25% inorganic fertilizers. Organic fertilizers are given as essential fertilizers, while half of the inorganic fertilizers are given when the plants are planted and the rest when the tillers are active. The results showed that: 1) Applying a combination of organic and inorganic fertilizers increased the percentage of productive tillers, weight of 1000 grains and weight of dry grain harvested per hectare. 2) Application of organic fertilizer + 75% NPK can increase grain weight by 4% compared to using only NPK fertilizer. The results of the study recommend that fertilizing rice with a combination of organic fertilizer + 50% NPK needs to be considered for increasing paddy grain production and improving the quality of rice fields.

Abstract

The golden snail (Pomaceae canaliculata) is an organism that destroys cultivated plants with a loss rate of 10-40%. The threat of the golden snail can become an opportunity that has economic and ecological value if it is used as liquid organic fertilizer (POCMAS-Plus). The POCMAS-Plus product, as a result of the training, can support sustainable agricultural development in Subak Lepud, Baha Village, and overcome the failure of rosella seedling growth due to less consistent growth. The activity aims to provide skills to subak members in making liquid organic fertilizer made from snails and applying POCMAS-Plus to rosella plants in the nursery phase. The implementation method consists of 1) Socialization activities and training on using golden snails as liquid fertilizer. 2) Demonstration of making liquid organic fertilizer and 3) application (POCMAS-Plus) to Rosella plants in the nursery phase. Paired T-test was carried out to determine the difference in the growth of rosella seedlings between those given and those not given POCMAS-Plus on growth uniformity, root length, seedling length, and the number of leaves. The pre-test results showed that most participants knew what organic fertilizer was. Still, only half knew the ingredients that could be used as liquid organic fertilizer, and most did not know about the process of making liquid organic fertilizer. All participants know and can make fertilizer independently. The POCMAS-Plus application increased the growth and uniformity of rosella seedlings. The results of the POCMAS-Plus application show that golden snails can be used as the main ingredient for making liquid organic fertilizer so that the growth and uniformity of rosella seedlings are better.

Abstract

The study entitled "The Effect of Dolomite Doses on the Quality and Storage Period of Salak Salak Pasir" has been carried out from April 2019 to January 2020, from the time of dolomite administration to harvest. The study was carried out in farmers' salak gardens in Pajahan Village, Pupuan District, Tabanan Regency and the Agrotechnology Laboratory, Mahasaraswati University, Denpasar. The study was conducted in the field and laboratory using a Randomized Block Design (RBD) with 5 dolomite dosage treatments and 6 replications, so that there were 30 snake fruit plants used in this study. The dosage of dolomite that is applied and is a treatment consists of 5 levels, namely: D0 (0 kg dolomite per tree); D1 (1, 50 kg dolomite per tree); D2 (3 kg dolomite per tree); D3 (4, 50 kg of dolomite per tree) and D4 (6 kg of dolomite per tree). The effect of giving a number of dolomite doses on zalacca plants on the quality and shelf life of zalacca was observed from several parameters namely the parameters of fruit weight, fruit meat weight, seed weight, number of fruit skin scales, fruit flesh thickness and fruit shelf life. Statistical analysis results of the effect of dolomite administration on several parameters observed showed significantly different in the weight of the fruit seeds and very significantly different in the parameters of fruit weight, fruit weight, thick fruit flesh and shelf life of salak fruit. As it is known that dolomite in addition to containing Ca also contains Mg, which has a better effect on soils that have low Mg levels especially for fruit growth and yields From the results of this study it can be concluded that the quality of salak sugar in 1.5 kg dolomite dose significantly higher than the 6 kg dolomite dose; 4.5 kg; 3 kg, and 0 kg dolomite per tree indicated in the fruit meat weight parameters reached 35.06 grams and fruit meat thickness reached 1.02 cm. Giving several doses of dolomite in salak plants are 1.5 kg dolomite doses; 3 kg; 4.5 kg; and 6 kg per tree gives a shelf life of salak sugar which is not significantly different. The shelf life of zalacca sugar is significantly higher than that without dolomite when it occurs in dolomite doses of 1.5 kg per tree which is 13, 50 days. From the conclusion of this study it can be suggested that to improve the quality and shelf life of salak fruit, it is recommended that in salak cultivation be given dolomite 1, 5 kg per tree.
