Abstract

The condition of fishery resources in Barru Regency can still be categorized as good fishery and not yet widely used, due to lack of adequate fishing catch fisheries. One of the locations of fishing operations in Barru namely Mallusetasi waters. The dominant fishing gear used in fishing operations in Barru include seine trawl, fishing rod, gill net, tap chart and floating chart but still not giving optimal result. the goal in this program is the application of LED-based fishing technology and the determination of the frequency of sound can be useful for the fishermen community and increase the number of catch and environmentally friendly. This activity is divided into 3 stages namely the initial stage (preparation), the stage of implementation, and the final stage all of which was carried out approximately for 5 months. PKM has a promising potential both in terms of knowledge and its application. PIBER LEDFRESUR during its application gives effect to the number of fisherman catch and the amount of compression / economy of new bojo fishermen in new regency. With the use of PIBER LEDFRESUR the energy used is relatively small as well as the most gterpenting environmentally friendly. The catch of a fisherman usually 1 capture in 4 hours now using FIBER LEDFRESUR rose to 4 times in 4 hours, with a catch of 20 kg per catch

Abstract

Agriculture is generally defined as a cycle of management or cultivation of natural resources by humans, especially in the field of crop resources management. The cultivation process requires several supporting factors to run normally and well, the better the process of agricultural cultivation will be the maximum and the quality of the products produced, and vice versa. Factors determining whether or not the quality of the plant, is determined by 2 main factors, namely land or planting media and the maintenance process because the planting medium is where the growth of plants consisting of solid, liquid and air and the bodies of different content for each type of soil, In order for plant growth can take place properly then the regulator of water antata must be considered, because water directly affect the preparation of plant body and photosynthesis process. One of the most important factors in improving the quality of plants is at the pre-harvest stage, ie there is a watering stage. In the process of watering there is to be considered that the pattern or time of watering because it has a correlation to the process of photosynthesis, especially on horticultural crops are generally in demand by the community as food crops. Based on the main points of mind on the main problem that is, urban communities in the care of plants do not have much time in due to the density of human activity, in the care of the plants is very urgent attention to watering, plant watering done by farmers or urban communities today is generally still done traditional by using timbah or hose directly to water the plants, so in this way is still less efficient because it still rely on human power and not time saving, and the high level of heterogeneity in the distribution of water, then on the other hand many available plastic waste such as plastic cups, paint containers and other plastic containers. So the researchers make innovations and the need for the development of irrigation watering equipment drops with the gravity of automatic control system using plastic waste (LIPSTIK)

Abstract

Penelitian ini adalah penelitian rekayasa atau rancang bangun yang membahas tentang kerja dan unjuk kerja dengan alat pembelah buah kakao semi mekanis. Proses penelitian ini menambahkan pembuatan setiap komponen, memeriksa alat pembelah buah kakao serta melakukan pengujian. Penelitian ini menghasilkan alat pembelah buah kakao yang bekerja dengan menggunakan sistem tekan ( pers ), di mana pembua dapat mengaktifkan buah kakao hingga terbelah atau terpecah. Proses pengujian dilakukan pada kali ulangan, dengan sekali tekan dapat memecah tiga buah kakao.Hasil dari pengujian alat ini menghasilkan rata-rata kapasitas efektif alat 1126 buah / jam, kerusakan hasil rata-rata biji rusak 2,4%, biji tidak tersaring 57,8% menghasilkan persenikatan penuh 97,6% dan rata-rata persentase biji tersaring hanya 42,2%, serta rendemen 100%. Berdasarkan hasil penelitian yang diperoleh dari kerja mekanik pembelah semi mekanis ini meningkat dan dapat mengurangi kerja dan kerusakan biji yang dihasilkan menggunakan dengan pembelahan manual yang menggunakan pisau atau golok yang diperuntukkan untuk buah kakao yang dibelanjakan untuk diganti hama penggerek buah.
