Abstract

This research aimed to analyze and evaluate and identify the carcass profile of male limousin crossbreed cows slaughtered at The Slaughterhouse (RPH) Malang city. Three hundred male limousin crossbred cows, which are slaughtered within four months, were selected as study material. The identification of male limousin crossbred cattle based on physical characteristics documented in the RPH antemortem document and direct visual observation on the unique characteristic of brown and blackish-brown colors, horns, and black hooves, and tail hair, and compact body shape. The variables observed in this study included slaughtered age, body weight, carcass weight, carcass percentage, carcass components percentage, and carcass quality grade. The results showed that the average age was 34.86±3.04 months, with a mean bodyweight of 532,44±62,47 kg, carcass weight 287,76±45.22 kg, and carcass percentages 54.11±6,16 % with carcass components percentage: meat 82,15±1,56 % and bone 17,85±1,56 %, as well as carcass quality grade at the choice grade, according to the USDA. The carcass production profile of male limousin crossbreed cattle in Malang city slaughterhouse is not optimal according to male limousin cows' genetic potential related to the environment's adaptation process and the feed is given. Therefore, the carcass production profile shows the male limousin crossbreed cattle carcass potential to meet the meat needs, especially for Malang consumers.

Abstract

The study aimed to compare the growth and production of rice between three varieties, namely Ciherang, IR 64 (Membrano), and Inpari 23 (Aromatic) without or with soil amendment application (dolomite) on andosol soil from Karanganyar. The research design used was a split-plot with a Completely Randomized Design. The main plot is treatment without soil amendment (R1) and with soil amendment (dolomite) (R2). Subplots were Ciherang (V1), IR 64 (V2), and Inpari 23 (V3) varieties. Parameters observed were plant height, number of panicles, panicle emergence age, crown weight, root weight, root crown ratio, strawweight, grain weight, 1000 grain weight, and harvest index. The results showed that the variety factor had a significant effect (P0,05) on the age of panicle emergence and the number of panicles. The age of panicle emergence and the best number of panicles was found in the IR 64 variety. Variety factors had no significant effect on plant height, crown weight, root portion weight, root canopy ratio, strawweight, grain weight, 1000 grain weight, and harvest index. Soil amendment factors have no significant effect on growth, biomass production, and rice production. It can be concluded that the most superior rice growth and production is IR 64 variety followed by Ciherang and Inpari 23 varieties.

Abstract

Dendrobium sp is one type of orchid that is in demand by the public because of the various flower shapes and attractive colors but has a long growth period. Therefore, efforts are needed to accelerate the flowering phase of Dendrobium sp. The purpose of this study was to determine the effect of the hormone auxin in accelerating the growth of Dendrobium sp. The research was carried out using a completely randomized design with a 4x2 factorial pattern with 3 replications. The first factor was the treatment of hormone Auxin NAA (A1) and IBA (A2) then the concentration consisted of 4 levels, namely control (K0); 100 mg/l (K1); 200 mg/l (K2), and 300 mg/l (K3). Observations were made every month variables included plant height, number of leaves, length and width of leaves, number of roots, and length of roots. The results showed that the type and concentration of auxin (Naphthalene Acetic Acid) and (Indole Butyric Acid) interacted to support the growth of leaf length, leaf width, and root length of Dendrobium sp orchids. IBA auxin was more effective in promoting growth and rooting of Dendrobium sp than NAA hormone, the optimal concentration of 200 mg/l until the age of 3 months after acclimatization.

Abstract

The purpose of this research was to examine the effect of the concentration and the frequency of tofu wastewater and the interaction between concentration and the frequency of tofu wastewater on the growth and production of red chili (Capsicum annum L.) plants.  The method used in this research was a completely randomized design of a factorial pattern. The first factor is the concentration of tofu wastewater which is consists of 5 treatments, namely tofu wastewater (T0), tofu wastewater 25% (T1), tofu wastewater 50% (T2), tofu wastewater 75% (T3), and tofu wastewater 100% (T4). The second factor is frequency tofu wastewater (F) which consists of 3 levels, namely the frequency of tofu wastewater once time during the planting period on 14 days (F1), second times during the planting period which given when the plant is planted 21 and 42 dast (F2), and three times during the planting period, and which given when the plants were 14, 28, and 42 dast (F3)  with three replicates. The results showed that the type of tofu wastewater had a significant effect on the age of the first flowers, the total fresh fruit weight, and the total dry fruit weight. The frequency of tofu wastewater offering had a significant effect on the number of fruits planted. No interaction between the types concentrates on the frequency of tofu wastewater to vegetative and generative plant growth. The best result is the age at the first flower, the total weight of fresh fruit, and the dry weight of 100% tofu wastewater. The best number of fruit crops is the frequency of offering tofu wastewater as much as once watering.

Abstract

Fertilization is one of the factors that influence the growth and production of sticky maize. This study examined the effect of organic-NP enriched manure on the growth and yield of sticky maize. The study used a Randomized Complete Block Design (RCBD) with four replicates. The treatments are P0 (ZA + TSP), P1 (cow manure + ZA + TSP), P2 (goat manure + ZA + TSP), P3 (poultry manure+ ZA + TSP), P4 (cow manure + Gliricidia sepium + BP), P5 (goat manure + Gliricidia sepium + BP), P6 (poultry manure + Gliricidia sepium + BP). The parameters observed were plant height, number of leaves, chlorophyll content, cobs length, and cobs diameter. The results showed that the number of leaves, chlorophyll content in the generative phase, and cobs diameter in treatment P1 (cow manure + ZA + TSP) is equivalent to P4 (cow manure + Gliricidia sepium + BP), P2 (goat manure + ZA + TSP) is equivalent to P5 (goat manure + Gliricidia sepium + BP), and P3 (poultry manure+ ZA + TSP) is equivalent to P6 (poultry manure + Gliricidia sepium + BP). The cobs length in treatment P3 is significantly higher compared to P6. All treatments have no effect on plant height and chlorophyll content in the vegetative phase.
