Abstract

Farming the shrimp, fish and another commodity could produce large quantities of waste. Aquaculture waste can be formed as feces, residual feed and dead organism which are accumulated in a cultivation area. Generally, the waste is discharged directly into the water without filtration. Thus, one of the problems that are often faced by farmer is the low quality of pure water due to the high content of nutrients. Moreover, suspended solid pollutant will be formed that lead to eutrophication, oxygen depletion, and precipitation. The aim of this research is to analyze the solid waste pond tiger shrimp as fertilizer for the growth of Caulerpa lentiilifera. Here, the Random Design complete (RAL) and three times in Deuteronomy are used in the experiment. The parameters of one control and three treatment doses are used 0, 2, 4, and 6 g.L-1 respectively. The results showed that solid waste shrimp ponds can be used as fertilizer to meet the needs of Caulerpa lentillifera for growth and the results show the highest value is found in the dose of 6 g.L-1 with NO3- (4.58 ppm), NH4+ (3.34 ppm), PO43-  (2.03 ppm) and the value of the rate of growth and the PH are obtained (3.64 g.day-1) and (6,4-8), respectively. Keywords: Caulerpa lentillifera, growth rate, Nitrification, solid waste, Tiger Shrimp.

Abstract

The growth and the yield of eggplant plants are strongly influenced by the condition of the soil, and any damage to soil quality can cause unproductive plants according to its potential results. The addition of organic material in the form of biogas waste into the soil is expected to increase the yield of eggplant. This experiment aims at determining the best dose of biogas waste (sludge) to increase eggplant production. The experiment was carried out in Jember Lor village, Patrang, Jember, East Java with an altitude of ± 89 meters above sea level (masl). The experiment used a completely randomized design method (CRD) with 4 treatments, treatment L0: 0kg waste plant-1; L1: 0.6 kg of waste. L2: 1,2kg of waste plants -1 and L3: 2,2 kg of waste plants-1. Each treatment was repeated 6 times with a total of 24 plants. Based on the results of the study, there was a very significant effect of sludge on variables of plant height, flowering age, harvesting age, fruit diameter, fruit length, and fruit weight. Sludge does not show a significant difference in plant diameter variables. The best treatment to have reached the plant height, fruiting age, harvesting age, fruit diameter, fruit length and fruit weight was the treatment of using a sludge with the dose of 1.2 kg polybag-1 (L2) with a height of 102.8 cm, different ages of 30.83 HST , harvest age of 56.73 HST, fruit diameter of 35.93 mm, fruit length of 17.95 cm and fruit weight of crop reached 1.36 kg (37.61 tons ha-1).Keywords: biogas waste, cow dung, eggplant, sludge.

Abstract

The ripening of Porang compound fruit (Amorphophallus muelleri Blume) in one cob does not occur simultaneously but moves forward from the distal region to proximal. The ripe fruit is red, almost ripe is yellow and unripe is green. The study aimed to examine the growth potential and polyembryonic properties of Porang seeds derived from red, yellow and green fruits. These seeds were grown in different media with the expectation the best plant growth can be obtained. This research was a factorial experiment which was arranged in a completely random design and each unit observation has three replication. The factor I was the source of seeds. Seeds came from various fruit colors. Each of them is red (R), yellow (Y) and green (G). Factor II is a planting medium which had 4 types, M1, M2, M3, and M4.  M1 is combination of soil and husk charcoal (70%: 30%), M2 = soil: cocopeat (70%: 30%), M3 = soil: husk charcoal: cocopeat (70%: 15%: 15%) and M4 = just soil (100%). The results showed that the seeds derived from red fruit and planted on medium 2 (soil: cocopeat = 70%: 25%) potentially producing the best plant. The seeds also showed 100% polyembryony at 182 days after planting. In addition, the first, second and third shoots (originating from one seed) have different in height, canopy diameters, and petiole diameter. Keywords: Fruitcolors, planting media, polyembriony, Porang (Amorphophallus muelleri Blume).
