Abstrak. Aquaponic cultivation is an innovation in the fulfillment of fish and vegetable food needs. The types of fish and vegetables that have not been widely cultivated in aquaponics are tilapia and red cabbage. The aims of this experiment is to provides information on the best concentration of plant liquid organic suplements for the maintenance of red cabbage and tilapia in this aquaponic system. These are commodity have a variety of advantages and high production so it is necessary to conduct an aquaponic assessment of tilapia and red cabbage using liquid organic supplements of plants. This research was conducted gradually, namely the preparation of red cabbage seeds and fish seeds, fermentation of water, acclimatition of fish and research treatment. The research design uses a completely randomized design with four treatments and five replays. The treatment used by giving of liquid organic supplement concentrations merk SOC plants that differ in the integrated aquaponic tarpaulin pond system is treatment1 (0 ml/l), treatment2 (2.5 ml/l), treatment3 (5 ml/l) and treatment4 (7.5 ml/l) with each pond as much as 25 fish/pond. Aquaponic watering technique using DFT (Deep Flow Technique). Variables of red cabbage include the morphometry of the red cabbage plant (height of the plant, number of leaves, and wet weight). Tilapia variables include relative growth rate and fish survival rate. The results showed that the treatment of the concentration of liquid organic supplements of plants had a noticeable effect on the height of the plant, the number of leaves and the wet weight. Data of tilapia research with aquaponic system using tepal ponds include the relative growth rate of tilapia ranging from 2.84 - 3.90%/day and tilapia survival ranges from 88-92%.
Kudapan Keripik Jamur tangkos merupakan salah satu makanan ringan yang memilki manfaat bagi kesehatan, dimana kejamkos ini mengandung vitamin B, C, dan D. Kejamkos ini adalah olahan makanan ringan yang berbahan dasar jamur yang berasal dari janjangan kosong buah kelapa sawit (TKKS) yang sudah membusuk. Dimana bahan baku pembuatan KEJAMKOS ini sedikit sulit ditemukan karena pertumbuhannya tergantung musim dan kelembaban tempat janjangan diletakan. Jamur yang siap dipanen adalah jamur yang baru mau pecah yang ukurannya bisa sampai sebesar kepalan tangan orang dewasa. Jamur ini merupakan kelompok jamur mikroskopis yang memiliki nama ilmiah monilia sp. Jamur jenis ini akan terus tumbuh hingga sisa minyak dan protein dalam TKKS habis. Jamur ini tidak dipasarkan di pasar tradisional atau modern karena jamur ini tidak termasuk jamur yang tidak berkembang biak, jamur ini tumbuh subur sehingga mungkin sangat sulit ditemukan oleh masyarakat yang tinggal jauh dari perkebunan kelapa sawit. Maka ini merupakan kesempatan yang baik bagi para pemuda yang tinggal di sekitar perkebunan kelapa sawit untuk memanfaatkan jamur ini untuk diolah menjadi produk yang layak secara ekonomi dan bermanfaat.
Palm oil is a strategic commodity in the plantation sector in Indonesia. The government's recommendation in agricultural development, especially oil palm commodities, is to apply the principles of Good Agricultural Practices (GAP) in its cultivation. This study aims to determine the level of knowledge of farmers in the application of GAP in oil palm cultivation activities. The research sample was determined purposively with a total of 30 farmers. Data was collected by means of observation, questionnaires, and interviews. Data analysis was carried out using a qualitative descriptive method. The results showed that the level of farmers' knowledge of the application of GAP in oil palm cultivation was in the moderate category with a score of 1.83. Meanwhile, farmers in oil palm cultivation activities starting from land clearing, nursery, planting, maintenance, harvesting to marketing have not fully implemented the GAP principles. This is because there is no access for farmers to receive information about the GAP principle in oil palm cultivation
