Abstract

Plastic is the dominant packaging used by the public, so it has the potential to damage the environment. It is necessary to synthesize raw materials for making plastics that are degraded by microorganisms, namely bioplastics. Bioplastics are packaging materials that are synthesized from natural raw materials so that they can be degraded in the environment. The raw material used is corncob because it is abundant and the benefits are not maximized. Research is needed to examine the stages of the production process and the characterization of bioplastics from corncob waste. The purpose of this study was to examine the stages of the production process and the characterization of bioplastics from corncob waste. This study used a laboratory experimental method with descriptive analysis. The production of bioplastics consists of the stages of making cellulose, cellulose acetate, and bioplastics using the solution casting method. The stages of cellulose isolation include hydrolysis, delignification, pulping, and bleaching, which showed an increase in cellulose content from 32.14% to 79.36%. Cellulose is acetylated to become cellulose acetate and has an acetyl content of 11.70 ± 0.40% with a yield of 121.16 ± 0.98%. The production of bioplastics uses a composition of cellulose acetate and chitosan at 50%:50% (w/w) successively. The resulting bioplastic has a thickness of 0.345 ± 0.024 mm, a density of 0.83 ± 0.03 g/cm3, a moisture content of 13.13%, a biodegradation value of 95.19%, a water resistance of 205.57%, and is transparent. The mechanical properties of bioplastics include a tensile strength of 22.3 N/m, an elongation of 21.11%, and a modulus of elasticity of 0.307 Mpa.

Abstract

The direct seeding of rice (DSR) system has been widely practiced in various Asian countries because it is considered more efficient in water and labor and provides better benefits than transplanting systems. However, improvements in the management of this system practice are still needed, especially in cropping patterns and the use of appropriate varieties. This study examines the physiological characteristics, yield components, and yields of rice genotypes in transplanting and DSR systems. This research was carried out in the field with transplanting and DSR cultivation systems (drill and broadcast sowing) and used four superior lines and one national variety. A total of 25 treatment combinations were designed using a split-plot randomized complete block design (Split plot-RCBD) with three replications for each treatment. The results showed that rice grown with DSR had no different level of greenery and photosynthesis rate than rice in transplanting cultivation, but produced lower panicle length, the number of grains per panicle, the number of filled grains, and faster flowering time. Genotype IPB193-F-17-2-3 produced the highest productivity in wet DSR (drill and broadcast sowing) and dry DSR (drill sowing). Genotype IPB193-F-38-2-1 had the highest productivity in transplanting techniques and dry DSR (broadcast method). The productivity of the Ciherang variety in the DSR system (drill method) was not different from the transplanting system. This finding indicates that the direct seeding system using the drill method is promising for further development.

Abstract

Urea fertilizers and biofertilizers play an important role in potato (Solanum tuberosum L.) cultivation, but urea fertilizers are volatile and leach out easily that reduce their effectiveness. Urea coated with beneficial bacteria-enriched organic matter is expected to increase nitrogen used efficiency. The purpose of the experiment was to determine the ability of bacterial-coated urea (BCU) included Bacillus and Azotobacter to improve the growth, nutrient status and yields of potatoes grown in field; as well as to reduce urea dose. The experiment was setup in randomized block design with five treatments and six replications. The treatments were four combinations of the dose and formulation of BCU; and conventional urea fertilizer as control treatment. Application of both BCU formulation increased plant height as well as N and P uptake particularly when the recommended dose was used.  In contrast, the doses and formulation of BCU did not affect chlorophyll content. Application of BCU-A or BCU-B at the rate of 200 kg/ha increased tuber weight by 59% and 81% respectively.  Both high and low dose of BCU did not reduce the vegetative growth and yield compared to the plants fertilized with conventional urea. This experiment showed that BCU is considered to reduce the rate of Urea in potatoes cultivation.

Abstract

A study was conducted in nethouse at the Sustainable Agriculture Faculty at University Malaysia Sabah, Sandakan campus, to study the effect of using blue NPK fertilizers (12:12:17) with a different biochar rate (0, 1 and 2 tonnes ha-1). The objective of this study was to determine the optimum rate of NPK blue and/or biochar fertilizer on the growth and yield of okra plant using Silabukan soil and to determine the nutrient content found in the soil before and after the study. There are 15 treatments that have been used in this study and have 3 replicates for each treatment. The design used is a completely randomized design (CRD). Data were analyzed using ANOVA one way. The results for vegetative growth showed that the treatment of N5B3 (400 kg ha-1 and 3 tonnes ha-1) had the highest tree height of 185.7 cm and the highest number of leaves of 31 sheets. For the results of yield, the N4B3 (300 kg-1 blue NPK and 3 tonnes ha-1 of biochar) treatment showed the highest yield of 7 pieces of fruit and 22 cm long. For the results of soil analysis, N1B1 (0 kg-1 blue NPK and 0 tonnes ha-1 biochar) treatment showed the highest pH reading of 6.3. N2B1 treatment (100 kg ha-1 and 0 tonnes ha-1) shows the highest alumunium conversion readings of 1.5 cmolc kg-1. N4B1 treatment (300 kg-1 blue NPK and 0 tonnes ha-1 biochar) showed the highest availability of phosphorus 0.0592 mg kg-1. In conclusion, the N4B3 treatment (300 kg-1 blue NPK and 3 tonnes of ha-1 biochar) showed the best growth to produce a large amount of okra fruit about 7 pieces per plant.

Abstract

The porang plant (Amorphophallus muelleri B.) is a tuber plant. Porang plant propagation still uses conventional methods by using seeds or frogs that experience dormancy and take a long time to make seeds. The tissue culture technology approach through organogenesis is a solution for the supply of large-scale porang seed material. The research aims to determine the effect of TDZ (Thidiazuron) on the formation of organogenesis. This study used porang leaf explants grown on MS media. The research design used a completely randomized design with one factor, namely TDZ hormone at concentrations of 0 mg/L, 1 mg/L, 2 mg/L, 3 mg/L, and 4 mg/L. The results showed that leaf explants on the addition of TDZ hormone could form organogenesis indirectly, but gave a response to form shoots multiplication. TDZ concentration of 2 mg/L gave the highest proportion value in the parameter of callus formation power of 95%, regeneration power of 88%, and  number of shoots of 10.2 shoots.

Abstract

Sugarcane (Saccharum officinarum L.) is a plantation commodity that has an important role in the economy in Indonesia. The demand for sugar increases with the increase in population. Therefore efforts to increase sugar production by increasing the productivity of sugarcane, one of which is through the use of high quality seeds. Sugarcane Bud Chip seeds have the potential to produce sugarcane with high yields, but efforts to stimulate seedling growth really need to be increased. The use of Biostimulant from shallot extract needs to be tested on sugarcane seedlings because shallots contain the hormone auxin and vitamin B1 which are very necessary to increase the growth of sugarcane seedlings. Therefore this study aims to determine the effect of shallot extract concentration on the initial growth of sugarcane plants using the bud chip method and determine the best concentration. This study was conducted for 2.5 months and was designed using a non-factorial randomized block design with 5 concentrations of shallot extract including B0 (control/no extract); B1 (20%); B2 (40%); B3 (60%); B4 (80%). The parameters include the number of tillers, plant height, number of leaves, and root length. The results of this study indicated that the shallot extract gave a significantly different response to the growth of sugar cane seedlings, as seen in the parameters of the number of tillers, the number of leaves and root length. From the data obtained, shallot extract at a concentration of 40% was the best concentration for all parameters.

Abstract

Seed is an important component in increasing crop production and productivity. The availability of superior seeds of lowland rice nationally, including Central Sulawesi Province, is still very limited so that it becomes an obstacle in supporting the achievement of rice production. For this reason, an assessment of the seed supply model in the form of farmer groups is expected to be an alternative way to provide superior and quality rice seeds according to the wishes and preferences of farmers and available according to time. The research was carried out in three centers of lowland rice whose farmer groups have not been facilitated by the Department of Agriculture, both district and provincial. This study aims to 1. Determine the problem of fulfilling seeds at the field level and 2. To obtain a model of the seed production system at the level of farmers and farmer groups for the fulfillment of superior and quality seeds appropriately. The implementation of the activity consists of two stages: the first stage is the identification and characterization of seed potential and constraints and the second stage is the assessment of innovation and seed production technology at the level of breeder farmers and farmer groups. The results showed that farmers did not know about new high-yielding varieties including the procedures and requirements for plants to become seeds and difficulties in obtaining information related to seeds, so farmers planted existing varieties or expected for seed assistance. Yields and seed production at the three activity locations showed quite high yields, reaching 4.2 – 5.1 tons of seed/ha where in one ha production for seeds can supply seeds covering an area of ​​100 – 120 ha and can increase profits 2 to 3 times compared to grain production. In addition, the farmer group scale captive system can see the appearance of the plants that will be used as seeds
