2024-11-12T10:04:36+07:00

The Mucuna bracteata plant has various benefits in the world of oil palm plantations. Apart from being a ground cover plant, Mucuna bracteta is also a source of organic matter in oil palm plantations. The availability of less arable land makes the need to develop Mucuna bracteata cultivation as a benchmark in anticipation of the impact of the increasing availability of arable land in oil palm plantations. A study has been carried out to determine the effect of P fertilizer dose and watering frequency on the growth of Mucuna breacteata, which has been carried out in the Education and Research Garden (KP-2) Akademi Komunitas Perkebunan Yogyakarta which is located in Papringan, Depok, Sleman, Yogyakarta.

This study uses a factorial design consisting of two factors arranged in a complete random design. The first factor is the application of various doses of P fertilizer consisting of 3 levels, namely a dose of 1.5 g/plant, a dose of 3.0 g/plant, and a dose of 4.5 g/plant. The second factor is the frequency of watering which consists of 2 levels, namely 1 time a day and 1 time 2 times a day. The data of the research results were analyzed with various fingerprints at the real level of 5%. If there is a real difference, it will be continued with a test Duncan Multiple Range Test (DMRT) real level 5%.

The results of the study showed that the application of P fertilizer with doses of 1.5 g, 3.0 g, and 4.5 g as well as the frequency of watering 1 time a day and 1 time 2 times a day, showed that the interaction of the two treatments had a real effect on the parameters of plant height, number of leaves, fresh weight of crown, and dry weight of crown. Meanwhile, the parameters of root fresh weight, root dry weight, and total number of root nodules showed no real interaction. However, the interaction of the two treatments has an effect on each treatment alone or separately.

2024-11-12T10:00:37+07:00

Siamese orange (Citrus nobilis L.) was a type of fruit widely cultivated and produced in Bali, but its utilization was not optimal. Siamese oranges were usually used for religious ceremonies, and if excess, they would lead to waste. Siamese oranges contain vitamin C, phenols, flavonoids, and limonene as antioxidants. In addition, peel contains 30% pectin. The combination of Siamese orange fruit and peels into fruit leather with the Zero waste concept (utilizing all parts of the Siamese fruit has great potential as a functional food product). Functional food is a product that is not only filled with nutrients but also has health benefits. Fruit leather is a processed product from fruit skin that has plastic characteristics obtained from pectin content of ingredients. This study aimed to determine the right concentration of fruit peel puree addition to produce siamese fruit leather with the best characteristics and its potential as a functional food. Randomized Block Design (RGD) was used with six treatment levels in addition to siamese peel puree concentration (0%; 5%; 10%; 15%; 20%; dan 25%), repeated three times to obtain 18 experimental units. Observed variables included Vitamin C by UV-Vis spectrophotometry, antioxidant activity by DPPH, and moisture content by gravimetric and sensory characteristics on hedonic test of colour, taste, aroma, texture, and overall acceptance. Data obtained were analyzed using analysis of variance, followed by Tukey test. According to raw materials, the assumption of Siamese fruit leather with the right concentration of Siamese peel puree has potential as a functional food.

The study was to determine the effect of the time of application from NASA liquid organic fertilizer on the generative phase of sponge plants (gambas). In cultivating plants, there are several obstacles faced such as less fertile soil and fertilization that is not on target, causing production results to be not optimal. One way that can be done to increase crop production is using NASA's POC. This research was carried out at Lahan Percobaan of the Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The research method used was a study using a one-factor Randomized Group Design (RGD) with 4 treatments and 5 tests so that 20 experimental units with a NASA LOF concentration of 2 ml.l-1 water were obtained. The treatment to be applied is: P0 = without giving NASA LOF, P1 = giving NASA LOF (application at 2 WAP), P2 = giving NASA LOF (application at age 2 and 4 WAP), P3 = giving NASA LOF (application at age 2, 4 and 6 WAP). The results showed that the timing of NASA's LOF It has no effect on the parameters of fruit length, fruit diameter, fruit weight and number of fruits of sponge plants, but has a noticeable effect on the parameters of the number of male flowers and the number of female flowers of sponge plants. NASA's POC application with a time interval of 3 times (P3) showed the best results in the parameters of the number of male flowers as many as (9.32) flower florets and (3.28) florets the number of female flowers.

The purpose of this study was to determine the effect of AB mix nutrient mixture with tofu pulp POC and type of growing media on the yield of mustard plants (Brassica juncea L.) hydroponically wick. This research was conducted from February to May 2023 in Kesiman Pentilan Village, East Denpasar, Denpasar City. The altitude is 20 meters above sea level, with a rainfall of 2,757 mm, the average temperature is 20-300C. This type of research is an experimental study using factorial Group Randomized Design (RAK) consisting of two factors. The first factor is a mixture of AB mix and liquid organic fertilizer (POC) which consists of 3 levels. The second factor is the type of media consisting of 3 levels. The first factor of AB Mix nutrition with tofu pulp POC consists of 3 levels, namely: (K1 AB mix + 20cc POC), K2 (AB mix + 30cc POC, (K3 AB mix + 40cc POC). Factors of both types of media consist of 3 levels, namely: M1 (rockwool), M2 (husk charcoal), M3 (cocopeat). So that 9 combination treatments were repeated 3 times so that there were 27 plants. Interaction between the dose of tofu pulp POC + AB mix with the type of growing media (KÃ—M); Tofu pulp POC dose treatment + AB mix (K) and type of growing medium (M) had no real effect (Pâ‰¥0.05) on all observed variables. The absence of interaction indicates that the combined treatment of nutrients and media types has not been able to affect plant physiological processes. Although the two treatment factors are not real for all variables observed, emperically from this study shows that the nutritional treatment of AB mix + 20cc POC tofu pulp with rockwool planting media. Shows the highest economic yield weight, namely 17.378 grams and 17.711 grams.

2024-11-22T11:27:12+07:00

The application of integrated agricultural technology of duck and azolla rice can increase nutrients for plants from duck manure, loosen the soil, minimize weeding, and reduce farmers' production costs. Azolla protein content is about 23 to 30% and has a low lignin content so it is easily digested by livestock. This study aims to examine the effect of the number of ducks and azolla on the growth and yield of rice plants. The research will be conducted in Paloh Village, Samalanga District, Bireuen Regency from July to October 2024. This study used a factorial pattern Randomized Group Design (RGD) consisting of two factors. The first factor is the dose of azolla (A0: control, A1: 2 t ha^-1, A2: 4 t ha^-1), the second factor is the number of ducks per hectare (I0: control, I1: 800 heads ha^-1, I2: 1200 heads ha^-1, I3: 1600 heads ha^-1). The observed variables were plant height, number of tillers, potential yield ha-1 and rice yield. The results showed that azolla treatment on rice plants had a very significant effect on plant height at 45 days after transplanting, yield potential and rice yield but no significant effect on plant height at 30 and 45 days after transplanting, number of tillers at 30, 45 and 60 days after transplanting. The treatment of ducks in rice plants had a very significant effect on plant height at 45 days after transplanting, number of tillers at 45 days after transplanting and yield potential, significantly affected plant height at 60 days after transplanting and rice yield but had no significant effect on plant height at 30 days after transplanting, number of tillers at 30 and 60 days after transplanting. The best results were found at 4 tons of azolla ha-1 and 1600 heads ha-1.

The Influence Of Giving Fermented Coffee Waste Flour In Rations N Super Kampung Chicken Carcass Production 10 Weeks Of Age

2024-11-22T11:30:41+07:00

Livestock in Indonesia is currently experiencing very rapid development. This development is also accompanied by the increasing need for meat as a source of protein. One source of protein, especially native chicken. An increase in population size and poultry meat production levels needs to be balanced with an increase in feed availability. Super native chickens need quality feed for nutritional fulfillment in order to get optimal results. But the reality faced by farmers today is that the price of commercial feed on the market is very expensive. Feed ingredients that need to be used as alternative feed ingredients include agricultural industry waste, one of which is coffee skin. The purpose of this study was to determine the effect of giving coffee skin flour on the variable production of super-native chicken carcasses until the age of 10 weeks. The experimental design used was a Complete Randomized Design (RAL) consisting of 5 treatments and 3 repeats. The treatment is K0 (ration without the addition of fermented coffee skin flour), K1 (ration containing 3% fermented coffee skin flour.), K2 (ration containing 6% fermented coffee skin flour), K3 (ration containing 9% fermented coffee skin flour), and K4 (ration containing 12% fermented coffee skin flour). The results showed that the addition of fermented coffee skin flour in the ration did not have a noticeable effect (P>0.05) on all observed variables (cutting weight, carcass weight, carcass percentage, and non-carcass percentage). Giving fermented coffee skin flour as much as K3 (9%) absolute gives low cut weight and carcass weight results. While the variable percentage of carcass absolute showed the highest result in the K3 treatment (9%), and in non-carcass variables showed the lowest result in the K3 treatment (9%). Coffee skin is a corn collector but gives results that are not real on chicken carcasses, therefore it is hoped that there will be further research.

2024-11-22T11:36:08+07:00

The livestock sector plays a real role in national food security through the provision of animal protein, especially in the poultry sector, becoming one of the business fields that many Indonesians look at, one of which is raising super native chickens. Super native chickens need quality feed for nutritional fulfillment in order to get optimal results. But the reality faced by farmers today is that the price of commercial feed on the market is very expensive. Feed ingredients that need to be used as alternative feed ingredients are aking rice. The purpose of this study was to determine the effect of giving aking rice flour in the ration on the carcass cracking of super kampong chickens aged 10 weeks. The experimental design used was a Complete Randomized Design (RAL) consisting of 5 treatments and 3 repeats. The treatment is N₀ (ration without the addition of aking rice flour), N₁(ration containing 5% aking rice flour), N₂ (ration containing 10% aking rice flour), N₃ (ration containing 15% aking rice flour ), N₄ (ration containing 20% aking rice flour). The results showed that the addition of aking rice flour in the ration had an intangible effect (P>0.05) on the variables of carcass weight, chest weight, thigh weight, and back weight. While the variable wing weight shows a noticeable influence (P<0.05). Giving aking rice flour with a level of 10% (N₂) in the super native chicken ration gave the highest results on the variables of carcass weight, breast weight, pada weight, and back weight, while on the wing weight variable showed the highest value in treatment with a level of 15% (N₃). So it can be suggested that the provision of aking rice flour in the ration of super kampong chickens can still be tolerated up to the level of 15%.
