Abstract

White oyster mushroom (Pleurotus ostreatus) is a mushroom that has a variety of basidiomycetes that grow in tropical forests with high humidity. This mushroom is classified as edible, has even been cultivated for a long time by the community. Therefore, nowadays oyster mushrooms have a high value, it caused many people have cultivated these mushrooms. In this study we want to show a difference in the growth of the white oyster mushroom mycelium before given promol 12 (as control) and after being given 12 types of local microbial probiotics (PROMOL12). The method used is RAK (Design random groups). In this study, it was shown that the influence of the growth of white oyster mushroom mycelium was given PROMOL12. The growth of oyster mushrooms showed a difference for baglog 12 promol medium having an average growth of 0.6 cm and a growth period of 14 days, on the other hand baglog media control had an average growth of 0.7 cm with a growth period of 17 days. With the same environmental conditions, the average temperature is 27-29.5OC and the humidity is also not less than 60%, which has an average of 70% -81% which is in accordance with the growth of oyster mushroom mycelium.

Abstract

Hybrid Petri nets are modeling framework for a system that contains discrete and continuous states. In this paper, we construct a model of water treatment plant using Hybrid Petri nets. We choose hybrid petri nets because the water treatment plant contains discrete and continuous parts. The discrete part consists of the state of pumps and the continuous part consists of water volume in each processing unit. The Petri Nets obtained were further simplified to facilitate simulation. Through simulation we can determine the amount of water production with certain specifications.

Abstract

The agricultural sector is a sector supporting economy and welfare of many people in Indonesia. The direction of life development of Indonesian people themselves has been headed todominant direction, preferring practical and dynamic activity. This of course indirectly influences the point of view of the farmers to do their farming activities using more practical and modern things. Traditional ways have gradually been abandoned, although there are still some farmers we still use them. The development of modern technology in all fields, particularly in agriculture, is certainly very helpful for farmers in terms of saving time and energy. Artificial intelligence systems adopting human mindset into a computer programming language can create technology that works like a human, with training data that has been examined into programming languages.

AbstractThe chopper is a machine that is widely used to assist agricultural product processing activities, the most common problem is that the chopper machine will experience a decrease in efficiency if it is used frequently or the machine has passed a service life of more than three years. Another thing that often happens is that the main driving components, namely the dynamo, pulley, v-belt and chopper, wear out so that the efficiency of the engine decreases. Modeling using the petri net method aims to understand the dynamics that occur in the chopper. The chopper is said to be good in this modeling if it does not experience deadlocks and there are no long queues. The resulting Petri Net consists of four places and five transitions. Each place and transition describes the dynamics of the chopper. The transition  is a critical transition which, if enabled and fired, will cause the engine to turn off and make the queue to be chopped more and more. This happens because the initial assumption that is built requires that every enable transition will be immediately fired, namely the .Key words: Petri Net, Chopping Machine, ModelingAbstrakMesin pencacah merupakan suatu mesin yang banyak digunakan untuk membantu kegiatan pengolahan hasil pertanian, permasalahan yang banyak terjadi yaitu mesin pencacah akan mengalami penurunan efisiensi jika sering dipakai atau mesin tersebut sudah melawati masa pakai di atas tiga tahun. Hal lain yang sering terjadi yaitu komponen penggerak utama yaitu dynamo, pulley, v-belt dan chopper mengalami keausan sehingga efisiensi mesin mengalami penurunan. Pemodelan dengan menggunakan metode petri net bertujuan untuk memahami dinamika yang terjadi pada mesin pencacah. Mesin pencacah dikatakan baik pada pemodelan ini jika tidak mengalami deadlock dan tidak terdapat antrian yang panjang. Petri Net yang dihasilkan terdiri dari empat place dan lima transisi. Masing-masing place dan transisi menggambarkan dinamika pada mesin pencacah. Transisi  menjadi transisi kritis yang apabila enable dan difire akan mengakibatkan mesin off serta membuat antrian yang akan dicacah menjadi semakin banyak. Hal ini terjadi karena asumsi awal yang dibangun mengharuskan setiap transisi enable akan langsung difire, yaitu transisi .Kata kunci: Mesin Pencacah, Pemodelan, Petri Net
