Maintaining Storability of Shelled Rubber (Hevea Brasilliensis, Muell - Arg) Seed Using Potential Osmotic Solution and Fungicide

Rubber seed will loose its storability in a short time. Seed germination and fungal attack were factors that barrier the storage period. The research aim was to test the ability of the potential osmotic solution and fungicides to reduce seed germination. Completely randomized design with two factors and three replications, i.e: PEG 6000 (w/v): 0%, 15%, 30%, 45%, 60% (potential osmotic solution) and fungicide (active ingredients were pyraclostrobin + metiram ) (g / 1 kg seed): 0 g, 10 g, 20 g, 30 g and 40 g, were applied.The results showed that PEG 30% can inhibit seed germination up to 9.07% and 37.47% and fungicides 40 g/1kg can reduce fungal attack during storage of 12 and 16 days. Combination of PEG-6000 30% and fungicides 40g / 1 kg could maintain seed storability by pressing the seeds germination up to 10.67% and fungal attacks up to 18.00% during storage of 16 days with 96.80% germination

Maintaining Viability of Rubber Shelled Seed for Storage of 16 Days Period by Polyethylene Glycol 6000 Treatments

Rubber seeds have no dormancy, germinate rapidly and fungal growth is the limiting factor influencing storage period of seed viability. Solution of Polyethylene glycol 6000 (PEG 6000) have osmotic potential and osmotic adjustment that is used as a coating material is expected to be a preservative during storage. The purpose of this study was to test the effect of polyethylene glycol 6000 in inducing secondary dormancy by reducing the seeds germination and fungus growth to maintain the seed viability in storage period and to test seed viability and vigor after storage period. First stage of the study was using nonfactorial completely randomized design with four levels of polyethylene glycol with four replications, namely:PEG 6000 (w / v): 0%, 15%, 30%, 45%; The second step, was germination phase in germination tub after the storage period. The first study showed that concentration of 15% PEG 6000 to 45% were able to induced secondary dormancy by delaying seed germination from 0.67% to 0.33%, that significantly different from the 0% PEG 6000 (17.67%) that was able to reduced fungal seed from 16.33 to 26.33% andwas not significantly different in each treatment. The second study showed that PEG 6000 can maintain viability and vigor of seeds with seed germination above 97%, seedlings height 22.40 cm and number of leaves was 7.16. PEG 30% is the best concentration to increase the shelf life period of rubber seed andmaintained morphological characteristics after storage period. The higher the concentration of PEG 6000 the higher were the seed viability during shelf. The morphology and growth of the seedlings, had the same adaptability to the tub germination in planting medium

Coffee is one of the drinks that many people like, in general, coffee is made from real coffee beans which are processed into powder, it turns out that apart from the original coffee beans can also be made from other ingredients, such as bark which are popular in fruit-producing areas salak. The efficacy of coffee bark that is believed to increase stamina, reduce blood pressure and uric acid by the community, making coffee bark and producing coffee powder of bark is increasingly developing. The machine for grinding bark into powder is a machine used to grind zalacca seeds into powder to be used as bark coffee. The construction of the machine to be tested uses a suction method where the mechanism of bark through the inlet will be directed to a row of counter blades and after being filtered and driven by a thread shaft will pass through a row of fine counters / double processors. This machine will be tested for performance to determine the productivity of the machine such as Capacity (Q), Quality (K) and Power usage (P). The test was carried out using 5 kg of disunrice bark seed raw material with 3 times testing. The test results can be concluded that the maximum capacity of 33 kg / hour occurs the second test and the average machine quality is 94.47%. The maximum engine power of 1,253.3 Watts was obtained at the first test and the minimum power was 1,153.3 Watts on the 2nd test. The energy needed to grind 1 kg of bark into powder ranged from 38.13 W-h/hr

Traditional tools used in Aloe vera squeeze are classified as ineffective if used in medium and large scale processing. While the use of aloe vera as a raw material for a product is quite large, it is necessary to use an aloe vera squeezer that is able to overcome and handle the problem. So with the statement above, a machine that is capable of carrying out the process of curing and squeezing aloe vera for cosmetic ingredients is 30 kg / hour. In the process of making aloe vera machines and squeezing equipment used such as sawing machines, manual plate machines, lathes, welding machines, drilling machines, grinding machines. In the process of making this machine there is the main component workmanship and the processing time, namely the machine frame made of 37 "L" st time profile 9, 52 hours, screw press shaft made of 35 minutes S35 C material, the counter blade is made of material S 35 C 18 minutes, screw press made of 36 minutes plate material, screw press tube made of steel pipe material 2; 25 hours, inlet funnel from gallvanis plate material 2; 15 hours, outlet funnel made of gallvaniss plate material 1 25 hours, the aloe vera water filter is made from plate 1, 30 hours, a counter knife made of steel plate 2, 30 hours. From the time of the engine design, the total manufacturing schedule was obtained as the effective time was 26.7 hours, if the machining was estimated at 70% or (0.70), the machining time would be 26.7: 0.70 = 38.7 hours. so the reality time (reality in the field) is 38.7 hours
