Abstract

The long fermentation chain of coconut husk dust waste needs the addition of a bioactivator to speed up the composting process. Chicken manure is an opportunity for natural activators in the fermentation process of coconut husk dust waste. The time required in composting waste will be more optimal with the addition of bioactivators such as EM-4. The research was conducted at the organic fertilizer manufacturing site 'Minak Jinggo' which is located in Sumberbaru Village, Singojuruh District, Banyuwangi Regency and continued the analysis at the Soil Science Study Program Laboratory, Faculty of Agriculture, University of Jember. In the first coronation design using a Complete Randomized Design (RAL) with one factorial and 7 treatments. Compost content testing was carried out which included analysis of measuring pH, N, P. K, C-Organic and C / N ratio of compost. Compost results with time and content in accordance with Kepmentan No. 261 of 2019 were then designed an effect test experiment on mustard pakcoy plants with 2 factorials, namely the compost used and the dosage. Done with replays 3 times each treatment. The variables observed included plant height (cm), total number of leaves (strands), stem diameter (cm), plant leaf area (cm3), total fresh weight of the plant (g) and total dry weight of the plant (g). The data obtained will then be analyzed descriptively and statistically using Anova variety analysis at the level of 5% and an Honest Real Difference Test (BNJ) at a level of 95% confidence (P<0.05) to determine the differences between treatments. The comparative treatment of coconut husk dust waste material and chicken manure 30:70 with a composting time of 28 days is the right compost formulation and effect composting time to become compost in accordance with Kepmentan No. 261 of 2019 with an NPK content of 2.074%, C-Organic of 18.47, and A C/N ratio of 11.76. Compost treatment and the best doses on the growth and yield of pakcoy plants are in the treatment of adding compost with a ratio of 30:70 (K3) material and a dose of 20 tons perhektar (D2) which affects plant height growth, number of leaves, dry weight of plants, N content of plants, and the highest absorption of plant N. As for the wet weight of the plants, the highest is found in the compost addition treatment with a material ratio of 50:50 (K2) and a dose of 20 tons perhektar (D2).

Abstract

The spring onion plant (Allium fistulosum L.) has the potential to be developed considering the many benefits obtained from this plant, especially for various kinds of cuisine. Therefore, efforts to improve product quality and quantity need to be continued. The use of rabbit urine can help minimize the use of inorganic fertilizers. While cutting techniques will increase heat efficiency. This study aims to determine the effect of the seed length of spring onion seeds and rabbit urine fermentation on the growth of spring onion. This study used a factorial randomized block design consisting of two factors and three replications. The first factor includes cutting the seeds, namely (P1) 10 cm, (P2) 15 cm, and (P3) 20 cm. The second factor was the concentration of rabbit urine fermentation (U1) at 50 ml/l, (U2) at 100 ml/l, and (U3) at 150 ml/l. The results showed that there was an interaction between the dose of rabbit urine fermentation and cutting seeds on the growth of leek plants. The longer the seedling size, the more the response to rabbit urine concentration for leaf vegetative parameters and fresh plant weight. The highest yield was achieved with a seed size of 20 cm with a concentration of fermented rabbit urine of 150 ml/l with an average yield of 39.8 leaves per plant and a fresh weight of 442.52 grams per plant. There is a tendency for seed size to grow which can be stimulated by high urine concentrations, thus allowing the use of urine with higher concentrations and doses

Abstract

Crackers are a type of snack that is favored by consumers of all ages. Crackers can be consumed directly as a snack or as a side dish. One of the factors that determine the quality of crackers is the crispness. Durian is one of the many local fruits produced in Banjarnegara Regency. Durian consists of skin, flesh and seeds. When the durian season arrives, the seeds and skin of the durian become waste that is not utilized. The nutritional content of durian seeds which is quite a lot can be used as processed food that can be consumed by the community. Mocaf flour (Modified cassava flour) is a flour product derived from cassava which is processed using the principle of modifying cassava cells by fermentation. Based on the background of previous research results, it can be formulated the problem that underlies this research, namely how the right composition of durian seeds and mokaf flour and the length of time for boiling durian seeds to produce durian seed crackers are favored by consumers. This study aims to determine the level of consumer preference from the taste, color, texture and aroma of the durian seed crackers produced. This study used fresh durian seeds collected at durian sellers in the Sigaluh area, Banjarnegara Regency. The research was carried out at the Agricultural Product Processing Laboratory and Production Unit of the Banjarnegara Polytechnic Agroindustry Study Program. This study applies experimental research methods. The experimental design used was a completely randomized design with 3 replications. The hedonic test used 25 semi-trained panelists and the test results were analyzed using Anova. Furthermore, a follow-up test was used to determine whether there was a significant difference between the various treatments using the DMRT (Duncan Multiple Range Test) test. The results showed that the panelists preferred mokaf durian seed crackers which were processed with 100% durian seeds boiled by boiling for 30 minutes without the addition of mokaf flour. The panelists' preference for the color of the durian seed crackers was significantly different when the durian seeds were boiled for 30 minutes. While the aroma of the durian seed crackers produced is significantly different from the crackers by boiling for 30 minutes

Abstract

The tomato plant (L. esculentum mill) is a species of horticultural plant native to Latin America. It is one of the important horticultural plants and is included in the second largest vegetable after potatoes. Some of the main pests of tomato plants are B. tabaci and H. armigera which can lower production. Pest control using chemical pesticides can be reduced using growing refugia plants. This study was conducted to determine the effect of some models of reflux cultivation on natural enemy populations on tomato plants. This study used a Group Random Design consisting of 4 treatments: P0 (Control), P1 (Border Model), P2 (Strip Model), P3 (Random Model) each treatment was repeated 6 times. Research results show that the Border's reflux planting model has a good influence on the natural enemy population with the highest population obtained in the treatment of P1 (Border), with an average natural enemy population of 27 at most. This has a good effect on the decline of the pest population with the lowest average population obtained in the treatment of P1 (Border) and the highest pest population in the treatment of P0 (Control) at 2.85.
