Abstract

This study aims to determine the effect of atonic concentration, pruning, and the interaction between atonic concentration and pruning on the growth and yield of arabica coffee plants. This research was conducted at UPP. Catur Paramitha, Catur Village, Kintamani District, Bangli Regency with an altitude of 1250 m above sea level. The experiment lasted for 3 months from September to November 2021. The design used in this study was a Randomized Block Design (RAK) with 2 factors arranged in a factorial manner. The first factor is atonic concentration with 4 levels, namely Ao: 0 ml/l, A1: 1 ml/l, 2ml/l, and 3ml/l while the second factor is pruning which consists of 2 levels, namely, without pruning and with pruning. Observations on the observed variables were carried out every 2 weeks. The variables observed were branch length (cm), number of leaves (strands), number of new shoots (fruit), number of flowers (buds), number of fruit (fruit), and number of the stump (bunch). The results of statistical analysis showed that giving atonic concentrations to coffee plants had a significant to a very significant effect on the variables of number of leaves, number, number of new shoots, number of flowers, and number of fruits, and no significant effect on branch length and number of buds. The pruning treatment showed a very significant effect on all observed variables except for the variable length of branches and the number of buds which showed no significant effect. The interaction between the treatment of the effect of atonic concentration and pruning had a significant effect on the number of leaves, a very significant effect on the number of flowers and fruit, and an insignificant effect on the variable length of branches.

Abstract

The purpose of this study was to determine the effect of giving fermented sweet potato waste in the ration on the appearance of native chickens aged 3 - 10 weeks and to find out what percentage of the level of use of fermented sweet potato waste in the ration. This study used a completely randomized design (CRD) with 5 treatments and 3 replications. The treatments consisted of: R0 = ration without additional fermented sweet potato waste as control, R1 = ration containing 3% unfermented sweet potato was, R2 = ration containing 3% fermented sweet potato waste, R3 = ration containing 6% fermented sweet potato waste, R4 = The ration contains 9% fermented sweet potato waste. Each replication (experimental unit) used 5 native chickens so that the number of chickens used was 75. The use of sweet potato waste fermentation in the ration had no significant effect (P>0.05) on initial body weight, final body weight , weight gain,and feed convertion ratio. Feeding of fermented sweet potato waste to a level of 3% (R2) gave optimal results.

Abstract

The livestock sector plays a significant 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 are looking at, one of which is raising super-village chickens. To get fast growth of chickens and high productivity, sufficient feed is needed that contains the nutrients needed, both in quality and quantity. In order to reduce production costs as small as possible without reducing optimum production, it can be done by utilizing alternative feed ingredients that have high nutritional content, are easy to obtain and are inexpensive, namely banana peel waste. The purpose of this study was to determine the effect of fermented banana peel flour on the growth of 10-week-old super-village chickens. The design used in this study was a completely randomized design (CRD) consisting of 5 treatments and 3 replications, while the treatment was R0 = ration without fermented banana peel flour content. R1 = Ration containing 2.5% fermented banana peel flour. R2 = Ration containing 5% fermented banana peel flour. R3 = Ration with fermented banana peel flour content of 7.5%. R4 = Ration containing 10% fermented banana peel flour. Each treatment was repeated 3 times. The addition of fermented banana peel flour had a very significant effect (P<0.01) on the research variables of weight gain, final body weight and ration consumption. Meanwhile, initial body weight and FCR had no significant difference (P>0.05).

Abstract

Green grass jelly (Premna serratifolia L.) is a vine or coiled plant originating from Southeast Asia. Green grass jelly cultivation in Indonesia is still relatively low due to the difficulty of cultivating grass jelly plants, especially in terms of plant propagation. In general, propagation is done by stem cuttings. PGR that is often used is synthetic ZPT, one of which is Rootone F, but its use is less effective in terms of economy. it is necessary to substitute with ZPT derived from natural materials or from the use of household and industrial wastes such as coconut water, rice washing water, and tofu waste water. The purpose of this study was to determine the effect of soaking natural PGR in coconut water, rice washing water, and tofu waste water and to find out the best natural PGR ingredients for the growth of green grass jelly plants. This study used an experimental design used was a one-factor Completely Randomized Design (CRD), which consisted of four treatments and was repeated five times so that twenty experimental units were obtained with 3 samples each, requiring 60 plants. P1=0.1 gL-1 Rootone F (positive control), P2=450 ml.L-1 young coconut water, P3=450 ml.L-1 rice washing water, P4=450 ml.L-1 tofu dregs water.

Abstract

Cookies are biscuits made from low protein flour, and have a crunchy texture. Corn flour substitute was chosen because corn flour only contains <1% gluten. The main problem faced by corn commodity lies in the low sugar content as energy. To produce cookies that have nutritional value, palm sugar is added, where the constituent sugar is simpler than granulated sugar. This study aims to determine how the effect of corn flour substitution and the addition of palm sugar on the physicochemical and organoleptic characteristics of cookies. The design used was a Completely Randomized Design (CDR) with two factors and two replications, the first factor was corn flour substitution which consisted of four levels, namely 0%, 15%, 30%, 45%. The second factor is the addition of palm sugar which consists of three levels, namely 15%, 20%, 25%. Observations were made objectively including water content, ash content, protein content, fat content, carbohydrate content, crude fiber content and color. While subjectively include, color, aroma, texture, taste and overall acceptance. The results obtained the best formulation of cookies substituted with 30% corn flour and 20% palm sugar with a water content of 6.39%, ash content of 2.45%, protein content of 10.19%, fat content of 29.90%, carbohydrate content 51.08%, and 0.09% crude fiber content.

Abstract

Native chicken farms in Indonesia at this time have experienced very rapid development. One of the poultry that is currently being developed in Indonesia is the Super kampung chicken. The current reality is that the price of commercial feed in the market is felt by farmers to be very expensive, while feed is the largest component in poultry farming, where the cost of feed can reach 60-70% of the total production cost, so it is very important to look for other alternative feeds in the availability of ration feed ingredients. to keep production costs as small as possible without reducing optimum production. The use of sorghum seeds in the ration of super native chicken is (substitute) for corn because its nutritional content is almost the same as corn. The design used in this study was a completely randomized design (CRD) which consisted of 5 treatments and 3 replications. S0 (Control) of chickens that were not given sorghum, S1 of chickens that were fed a diet containing 7.5% sorghum, S2= 15%, S3= 22.5% and S4= 30%. The arrangement of the 3-story cage with a total of 15 plots, each containing 5 chickens, so that 75 chickens were used with a body weight range of 183.2-210.0 g. From the results of the study, the administration of various levels of sorghum did not have a significant effect (P>0.05) on final body weight, weight gain, ration consumption, and ration conversion of super-village chickens aged 3-10 weeks. In the administration of various levels of sorghum at S0 (Control) it was higher than the S1, S2, S3, and S4 treatments on final body weight, weight gain, ration consumption, and ration conversion for super free-range chickens aged 3-10 weeks.

Abstract

Abstract This study aims to determine the intensiveness of sea urchins (Echinoidea) and the community structure of sea urchins in the seagrass ecosystem at Batu Jimbar beach, Sanur, Bali Province. In this study, the stations were determined based on the distribution and cover of seagrass so that there were three stations, namely station I located at the coordinates 115 ° 15'58.17 "E - 8 ° 41'52.87"S, while station II was located at coordinates 115 ° 15'59.34 "E - 8 ° 41'48.15"S, and Station III is located at coordinates 115 ° 16'0.16 "E - 8 ° 41'43.42"S. Sampling was carried out at the lowest tide at the three stations and analyzed using species composition, density, relative density, diversity index, uniformity index, and dominance index.The research results were found 8 types of sea urchins were found consisting of 4 families, namely the Diadematidae family (Echinothrix calamaris, Diadema setosum, Diadema savignyi and Diadema palmeri), Toxopneustidae family (Tripneustes gratilla and Pseudoboletia maculata), Echinometridae family ((Echinometra mathaei) and Stomopneustidae family (Stomopneustes variolaris).The highest density of sea urchins was in Diadema setosum as many as 149 individuals from the three stations with a density value of 0.40 individuals / 375 m2 , while the lowest density for sea urchins was 1 individual / 375 m2 . The highest relative density was in the type of Diadema setosum as much as 149 individuals / 375 m2 and the lowest relative density was in the type of Diadema palmeri as many as 1 individual / 375 m2. The structure of the sea urchin community on Batu Jimbar beach, Sanur shows that from all stations, the value of diversity is moderate with a value of 1.65, the uniformity value is not evenly distributed with a value of 0.00349 and a dominance value of 0.22 it can be concluded that there are no species. which dominates at Batu Jimbar beach in Sanur.
