Use Of Liquid Organic Fertilizer Fish Waste And Chicken Manure Fertilizer On The Production Of Pumpkin (Cucurbita Moschata)

The study was carried out at altitude of ± 27 mdpl using factorial randomized block design (RAK). Firstly, Fish Waste POC (P) with 3 treatment levels, P1 = 20 ml/l water, P2 = 30 ml/l water and P3 = 40 ml/l water. Secondly, Chicken Manure (K) with 3 treatment levels, K1 = 0.75 kg/plot, K2 = 1.5 kg/plot and K3 = 2.25 kg/plot. The observed parameters were fruit length, fruit diameter, number of fruit per plot and fruit weight per plot.Based on the study, it was found that Fish Waste POC did not significantly affect on all the parameters observed. Chicken manure had a significant effect on the observed parameters, fruit length, fruit diameter and fruit weight per plot, while the combination of both treatments showed that there was no significant effect on all observed parameters.


INTRODUCTION
Pumpkin is from North America. Pumpkin can grow well with sufficient rainfall throughout the year. In Indonesia, this pumpkin is still classified as a new type of plant and because of limited stock and the farmers have not cultivated it much. Even now, this pumpkin is still 'exclusive'. Recently, pumpkin has become a trend in some circles as an alternative food and it can be found easily in some modern markets. The taste of this pumpkin is sweeter than the local pumpkins and so is its soft texture. It contains more calcium which is good for bone growth. Apart from being an alternative food, pumpkin is popular as well as a complementary food for breastfeeding that highly nutritious for young mothers who have children from one year old to under five years old. This round pumpkin has variety nutrient content such as vitamin A, iron, folic acid, and high fiber. The orange color of pumpkin contains carotene, antioxidant that converts vitamin A and reduce the risk of cancer. Pumpkin also contains B complex vitamins such as folate, niacin, vitamin B-6, thiamin, pantothenic acid, as well as mineral such as copper, calcium, iron and phosphorus (Kurniati et al, 2018).
One of the efforts that can be done to improve the welfare of farmers is by cultivating plants that have high economic value. Moreover, this pumpkin has higher price than the local pumpkin and it is still a rare plant for the farmers at several places in Indonesia. This pumpkin is a good prospect to be developed to increase food diversity as an alternative foodstuff with high nutrition and for the farmers' income as well (Imani and Mudji, 2019).To support the program from the government in creating healthy environment and society of its implementation is by a sustainable agricultural system in creating an environment with socioeconomic, ecological principles. In this case, it is very important to pay attention to inputs to maintain environmental quality and utilize natural resources as one of the managements in cultivating plant species. The solution to improve and to maintain safe environment for living things, especially for human safety from hazardous materials of agricultural products that will be consumed by utilizing organic materials in Indonesia and expected to be free from harmful substances. Organic fertilizer is one of the fertilizer that has good potential to improve the land that is used as plant media because of containing macro and micro nutrients needed by plants.
Fish waste can cause pollution if it is left therefore it should be fermented first, with the elements contained to decompose that can be absorbed easily by the plants and chicken manure. In this study, to support sustainable agriculture, fish waste is processed into POC and chicken manure will be processed into compost. Fish waste has the potential to pollute the environment and cause various diseases. The content of N and protein of fish waste can be used as the essential nutrient such as N, P, K that needed by plants (Efendi et al., 2016) and (Suartini et al., 2018).Chicken manure has higher P nutrient content than other manure. P element that can help root growth, stimulate the formation of flowers and fruit and as a source of plant assimilation and respiration (Andrians et al, 2015).Based on this information, the authors conducting research using organic materials to cultivate pumpkin in producing healthy environment and products that will be consumed well by the consumers.

III. RESULT AND DISCUSSION Fruit Length
Observation data on fruit length on use of fish waste and chicken manure according to Duncan's method can be seen in table 1.  The picture 1 showed that fruit length increased by 2,25 kg/plot with positive linier and ŷ equation = 0,52x + 20,393, while r = 0,8795. From the picture above, it can be seen that the use of 2,25 kg/plot K3 chicken manure had the best result from the fruit length with an average 21.48 cm as chicken manure can increase the fruit length. The more doses of chicken manure given, the longer the fruit length will be.

Fruit Diameter
The observation data of fruit diameter on fish waste and chicken manure according to Duncan's method in table 2. and K3 (7.86 cm) treatment. It is assumed that the application of chicken manure at a dose of 2.25 kg/plot produced larger fruit diameter. The content of sufficient K nutrients in chicken manure can stimulate fruit growth in plants in order that the size, taste and color of the fruit will be maximized. According to Atmaja's (2017) statement, potassium is a mobility nutrient in soil that plays a major role in transporting photosynthetic products from leaves to reproductive and storage organs, including fruit, seeds and tubers. Safuan (2007) states that sufficient amount of K nutrients can guarantee the function of leaves in fruit growth and the amount of sugar in fruit, then K nutrients can improve fruit size, taste and color. Furthermore, the use of fish waste POC had no significant effect on the diameter parameters of the pumpkin due to low nutrients in the POC of fish waste used. According to the statement of Pasta et al (2015) plants will not have maximum crop yields when the important nutrients are not sufficiently available. Fertilization can increase crop yields both quantitatively and qualitatively. Fruit diameter of pumpkin with chicken manure can be seen in picture 2.

Fig 2.
Chart of pumpkin diameter used chicken manure. Picture 2 shows that fruit diameter with an increase 2.25 kg/plot has a positive linear relationship with the equation vŷ = 0.2303x + 7.3697, with r = 0.9144. From the picture above, the use of K3 chicken manure 2.25 kg/plot, has been able to show the best result from pumpkin diameter with an average 7.86 cm. Therefore chicken manure can improve fruit diameter. The more dose of chicken manure given, the more the diameter of the fruit will increase.

Number of Fruit per Plot
Observation data on the number of fruit per plot used fish waste and chicken manure according to Duncan's method can be seen in table 3.

IV.
CONCLUSION AND SUGGESTION Conclusion 1. Fish waste POC did not significantly affect on the growth parameters and production pumpkin. 2. Chicken manure has a significant effect on growth parameters and pumpkin production. 3. The combination of both treatments did not significantly effect on growth parameters and pumpkin production. 4. The best dose in K3 treatment, leaf area 153.48 cm2, fruit length 21.48 cm, fruit diameter 7.86 cm and fruit weight per plot 7.23 kg.

Suggestion
As an organic material, chicken waste can help the growth and yield of pumpkin, therefore it is important to do research in different places to get more extensive information on the pumpkin development with high economic value.
