Abstract

 Diperlukan pengetahuan dasar tentang besarnya energi dan gaya yang dibutuhkan pada proses pemecahan cangkang biji kemiri untuk mendapatkan daging biji kemiri bulat utuh. Penelitian dilakukan dengan metode menjatuhkan biji dari berbagai level ketinggian kemiri dan metode menjatuhkan beban mengenai biji kemiri. Hasil penelitian memperlihatkan bahwa dengan metode menjatuhkan biji kemiri dari berbagai level ketinggian diperoleh bahwa ketinggian optimum untuk memecahkan biji kemiri pada posisi intersep C dengan kadar air 6%  adalah dari ketinggian 9 m dengan gaya sebesar 1,52 N. Sementara dengan metode menjatuhkan beban 209,7 gr mengenai biji kemiri diperoleh gaya 6,52 N dan menjatuhkan beban 182,64 gr diperoleh gaya 6,26 N. Untuk keseluruhan metode dibutuhkan energi sebesar 1 joule untuk memecahkan cangkang biji kemiri.   Basic knowledge about amount of energy and breaking force of the candlenut deshelling process is needed to get a whole round kernel. The study was conducted by dropping the candlenut from various level of height and dropping the load on the candlenut. The result showed that the method of droping candlenut from various levels of height was obtained that the optimum height to break the candlenut in the intercept C position with a water content of 6% was 9 m with a force of 1,52 N. While by dropping a load of 209,7 gr obtained a force of 6,52 N and dropping a load of 182,64 gr obtained a force of 6,26 N. For the whole method an energy of 1 joule is needed to break the shell of the candlenut.

Abstract

North Sumatera is the third largest producer of eggplant, therefore, postharvest handling of eggplants needs to be done, precooling, to maintain physic quality of eggplant from farming to consumer. Temperature is the one of main factor to effect respiration rate and change in physical quality of eggplants. Precooling and cold storage is applied. Predicting of respiration rate based on Arrhenius Equation. Result research showed that high score activation energy is precooling 10 minute, precooling 20 minute, and the lower score is non precooling. The best combination of treatments eggplant is precooling and then cold storage.

Abstract

Chyperus rotundus L. is a weed that is very fast spreading, growing and developing. Nut weeds can have a high adaptability seen from the ability to grow in various types of land. Starting from dry land, humid land to wet / inundated or muddy land. Sandy, clay or sandy loam land. This nut weed also has a high competitive power in terms of its ability to compete with other weeds, to keep growing and tends to be the dominant weed in a planted area. Various attempts were made to suppress the growth of this weed nut. Mulch is a method used to suppress the growth of nut weeds in this study. There are three types of mulch used in this study, namely rice husks, rice straw and reeds and control treatment. The three mulches were applied to two thicknesses, namely the thickness of 250 gr / plot and 500 gr / plot. The results showed that the inorganik mulch treatment of rice husks, straw and alang alang and its thickness of 250 g / m² and 500 g / m² did not have a significant effect in suppressing the growth of nut weed (Chyperus rotundus L.). Straw mulch first undergoes decomposition compared to rice husk mulch and Imperata, so that the percentage of growth of shallot (allium cepa L.) plants is higher than with submerged mulch and reeds.

Abstract

Corn is the second important food crop commodity after rice. Besides being used as food, corn is also used as animal feed. The low yield of maize is caused by many factors including physical factors (climate, soil and land types) and biological factors (varieties, pests, diseases and weeds), as well as socio-economic factors. The polyphagous nature of Helicoverpa armigera and the unavailability of varieties that are resistant to these pests have caused control practices to be carried out to date still depend on the use of insecticides. Biological control agents such as M. anisopliae, Beauveria bassiana, and Bacillus thuringiensis are the main control components. Utilization of biological agents has several advantages, especially selectivity, although it must be admitted that it is not as effective as insecticides with chemically active ingredients. The use of entomopotagen fungi is an environmentally friendly pest control and can be propagated by farmers. The aim of this study was to determine the effectiveness of environmentally friendly entomopathogenic fungi in controlling corn cob pests (Helicoverpa armigera) and corn stem borer (Spodoptera frugiferda) in Banjaran Deliserdang Village. The research method used is non-factorial RAK. From this study it was found that the intensity of S. frugiferda attack with the use of the entomopathogenic fungus B. bassiana showed the best effect with the intensity of S. frugiferda attack which was 9.28% while the H. armigera pest used B. bassiana with an attack intensity of 9.08%. The use of B. bassiana can reduce the attack of S. frugiferda pests on corn plantations.
