This research was carried out at Kintamani District, Bangli Regency, Bali-Indonesia, from February to October 2019 with aimed to overcome the failure of fruit-set and fruit drop of Siam orange on off-season period through application of mycorrhizal inoculants and ZnSO4 micro fertilizer dosage. This experiment was arranged as a randomized block design consisted of 2 factors.  The first factor was mycorrhizal inoculant (0, 50, 100 and 150 g/tree), while the second factor was the dosage of ZnSO4 micro fertilizer (0, 5, 10 g/tree). All treatments were repeated 3 times. The results showed that the interaction between mycorrhizal inoculant treatment and ZnSO4 micro fertilizer dosage did not significantly affect all of the variables observed.  Mycorrhizal inoculant dose 150 g/tree could overcome the failure of fruit-set and fruit drop and improved the quantity and quality of fruit of Siam oranges on off-season, which was reflected by increased number of fruits harvest per tree (249,00 fruits), weight per fruit (106,10 g), weight of fruit harvested per tree (26,34 kg) and total dissolved solids (13.52% Brix), or increase 31,44%; 18,15%; 54,58%; and 35,74%, respectively, compared to without mycorrhizal inoculant i.e 189,44 fruit; 17,04 kg; 89,80 g and 9,96% Brix.

Fertilization Response to Off-Season Production and Fruit Quality of Salak Gula Pasir (Salacca Zalacca cv. Gula Pasir) and water and Chlorophyll Content of Leaves. Naturally salak Gula Pasir (Salacca zalacca cv. Gula Pasir) flowers every three months a year, but only one to two seasons of the flowers can develop into fruit. Failure of flowers develop into fruit, usually call fruit-set failure, causes the fruits be available seasonally in a short time period, only 2-3 months a year, i.e. during the harvest time (on-season period) from December to February. This research aimed to know response of fertilization to off-season production and fruits quality of salak Gula Pasir and its ralatinship to water and chlorophyll content of leaves. The study used a randomized block design with the treatment was fertilization, consists of 14 levels (fertilized according farmers’ way with leaf midrib only/control, fertilized with compost, mycorrhizal biofertilizer, inorganic NPK, combination of farmers' way and compost, combination of farmers’ way and mycorrhizal biofertilizer,  combination of farmers' way and inorganic NPK, combination of compost and mycorrhizal biofertilizer,  combination of compost and inorganic NPK,  combination of mycorrhizal and inorganic NPK,  combination of farmers’ way, compost, and mycorrhizal biofertilizer,  combination of farmers’ way, compost, inorganic NPK,  combination of farmers’ way, mycorrhizal biofertilizer and inorganic NPK, and  combination of farmers’ way, compost, mycorrhizal biofertilizer, and inorganic NPK). Each treatment was repeated 3 times. The study was carried out in the off season period from April to Nopember 2018 at the production center of salak Gula Pasir plantation i.e. at Sibetan Village, Bebandem District, Karangasem Regency. The results showed that the highest fruit weight per tree at the off-season was obtained on combination of fertilization of farmers' way and mycorrhizal biofertilizer  (of 2536.67 g) and the lowest was on  control/fertilized according farmers’ way  (1,220.00 g). Fertilization with compost, mycorrhizal biofertilizer, and inorganic NPK singly, or by combining it, increases the quality of off-season fruit of salak Gula Pasir, reflected by the increase of weight per fruit, fruit diameter and fruit sweetness compared to control. The lower of yield per tree and quality of fruit on control compared to other fertilization treatments was relate to low relative water content and chlorophyll content of leaves.

The purpose of this reseach was 1) to determine the effect of temperature and acid type on hydrolysis of taro yam starch on the characteristics of glucose, 2) to determine the exact temperature and type of acid in taro starch hydrolysis which produced the best glucose characteristics. This reseach uses Randomized Block Design of factorial pattern.. The first factor is the hydrolysis temperature of taro yam starch at temperatures of 80°C, 90°C and 100°C. The second factor is the acids type of HNO3, H2SO4 and HCl, each with 7% acid concentration. Each treatment is grouped into 2 based on the implementation time. The variables observed were reduction in sugar content, total sugar, dekstrose equivalent (DE), total dissolved solids and clarity. The results showed that the temperature treatment and acid type had a very significant effect (P<0,01) on reducing sugar content, total sugar and hydrolyzed dectrose equivalent (DE) values. Temperature treatment has a significant effect on total dissolved solids and does not significantly affect clarity. The treatment of acid types has significant effect on total dissolved solids and clarity. Temperature treatment and type of acid interact with reducing sugar content, total sugar, and DE values, do not interact with total dissolved solids and clarity. The highest yield was obtained by reducing sugar content of 3,06%, total sugar 5,64% and DE value of 54,24% in HCl at 100°C. The total dissolved solids in H2SO4 and HCl at 100°C were 5,15°Brix and the clarity of HCl at 100°C was 0,02. The best glucose characteristics at HCl was 90°C which was not significantly different from HCl at 100°C. Keywords: sugar, hydrolysis, taro yam, starch, acid, glucose

Melon (Cucumis melo L.) is one of potential horticultural crop in Indonesia. Unfortunately, melon production is currently unable to meet national demand. The objective of this study was to investigate the effect of biofertilizer, varieties and interaction between the dose of biofertilizer and varieties on the growth and yield of melons. The study was conducted in January-April 2021 at Paloh Lada Village, Dewantara District and the Laboratory of Agriculture Faculty, Universitas Malikussaleh. These experiments were arranged in a Factorial Randomized Block Design (RBD) with two factors. The first factor was biofertilizer (P) consisting of 4 levels: P0 (0 ml/L), P1 (5 ml/L), P2 (10 ml/L) and P3 (15 ml/L) and the second factor was melon varieties (V): V1 (F1 Pertiwi Anvi) and V2 (F1 Action 88). There was 8 treatment combinations with 3 replications, resulted in 24 experimental units. The interaction between biofertilizers and varieties gave significant effect on the growth and yield of melon, while the interactions between bio fertilizer did not differ on all variables observed. The application of biological fertilizer 10 ml/L on V1 variety (F1 Pertiwi Anvi) is recommendable. There was an interaction between of biological fertilizers and melon varieties on the total dissolved solids (Brix %).

This research was conducted in Belancan Village, Kintamani District, Bangli Regency, Bali, Indonesia, from December 2020 to July 2021, which aimed to increase production and fruits quality of Siam orange with calcitor fertilizer and concentration of neem leaf extract. The study used a randomized block design, factorial with 2 factors and 3 replications. The first factor was calcitor fertilizer consisting of 4 concentration levels, i.e., 0 cc/l/tree (K0); 2 cc/l/tree (K1), 4 cc/l/tree (K2), and 6 cc/l/tree (K3), while the second factor was neem leaf extract consisting of 3 concentration levels, i.e., 0% (M0), 5% (M1), and 10% (M2). The results showed that the interaction between calcitor fertilizer and neem leaf extract concentration had no significant effect on all observed variables. Calcitor fertilizer with a concentration of 6 cc/l/tree could improve the quality of Siam orange fruit, which was reflected by the increase in the number of fruit per tree (106.44 fruit), weight per fruit (114.08 g), weight of fruit per tree (14 .37 kg), fruit diameter (6.89 cm) and total dissolved solids (11.52 %brix) or increased by 27.56%, 7.54%; 40.74%; 12.58% and 44.72%, respectively, than those of control. While in the treatment of neem leaf extract at a concentration of 10% increase the number of fruit per tree (107.73 fruit), weight per fruit (117.44 g), fruit weight per tree (16.04 kg), fruit diameter (7.58 cm) and total dissolved solids (10.83% brix), or an increase of 69.44%; 18.76%; 78.84% and 42.31%, respectively, than those of control.
