Abstract:The Consumption of fruit and vegetables by the community is inseparable fromthe waste generated. Conventionally, fruit and vegetable waste is thrown away, or forpeople who have livestock or livestock, the waste is used for feed. This is of course veryunfortunate, given the fact that optimal fruits and vegetables can be utilized. Utilizationof organic waste as animal feed ingredients as conventional compost material. If organicwaste is made into compost, the benefits are only given to plants. It is different if organicwaste is made into animal feed, which is beneficial for livestock, and from livestockobtained from livestock manure which can be made compost. However, organic wasteused for animal feed, easy to rot and voluminous (large) processing techniques areneeded to improve the future of storage, facilitate storage, and to enhance the antinutritionaleffects that usually contain alkaloids.Keywords: Waste, Fruit vegetable, Processing techniqueAbstrak:Konsumsi buah dan sayur oleh masyarakat tidak lepas dari adaya limbah yangdihasilkan. Secara konvensional, limbah buah dan sayur dibuang begitu saja, atau bagimasyarakat yang memiliki hewan ternak atau peliharaan, limbah tersebut dijadikanpakan. Hal ini tentu saja sangat disayangkan, mengingat sebenarnya limbah buah dansayur tersebut masih dapat dimanfaatkan secara optimal. Pemanfaatan limbah organiksebagai bahan pakan ternak ataupun sebagai kompos secara konvensional dinilaimemiliki kelemahan. Jika limbah organik dijadikan kompos, manfaatnya hanya diberikankepada tanaman. Berbeda jika limbah organik dijadikan pakan ternak, yang bermanfaatbagi ternak, dan dari ternak diperoleh kotoran ternak yang dapat dijadikan kompos.Namun, limbah organik yang dijadikan pakan ternak secara langsung, bersifat mudahmembusuk dan voluminus (bulky) sehingga diperlukan inovasi teknik pengolahan limbahuntuk memperpanjang masa simpannya, mempermudah penyimpanan, dan mengurangiefek anti nutrisi yang biasanya berupa suatu alkaloid.Kata Kunci : Limbah, Buah sayur, Teknik pengolahan

Abstract

The progress of a country cannot be separated from the role of energy, because with the existence of advanced energy it will be able to accelerate the progress of the country itself, energy itself is divided into 2 namely fossil and renewable energy. One of the renewable energies is the use of geothermal energy which can be converted into electricity through the photovoltaic effect. Indonesia itself is a country that is crossed by the equator so that it gets a lot of heat supply. The use of solar panels can be applied to the Knapsack Sprayer as an effort to minimize the use of fossil energy which is used as the main energy for producing electrical energy. This research is to see the effect of the use of polycrystalline solar panels in terms of a predetermined angle of inclination. This type of research is experimental research by controlling the angle of inclination in this case 25 degrees. The measurement of this research uses a digital DC avometer with its own power supply which will display the amount of charging current for the Knapsack Sprayer battery. Prototype testing is carried out after making the prototype, the manufacture starts from installing the panel on the knapsack sprayer and being given a holder. The test was carried out in a few days, the results obtained were in the form of a large charging current in the solar panel system. The results of this measurement will be calculated using the charging time formula to find out how long it takes to charge the battery on a monocrystalline panel in terms of an angle of 25 degrees. Based on the results of the tests and calculations, the data in the form of battery charging current using polycrystalline panels at an angle of 25 degrees in the first test was 0.44 amperes, the second test was 0.43 amperes and the third test was 0.48 amperes. From the test results, it is calculated and produces an average charging value using polycrystalline solar panels for 10.6 hours.
