Abstract

This study was conducted to determine the growth performance and profitability of broilers chicken with vermi meal supplementation under a total confinement management system. A total of 60 broiler chickens were randomly distributed to four dietary treatments: T1= commercial feed (CF), T2= CF+2% vermi meal (VM), T3= CF+3% VM, T4= CF+5% VM inclusion in a completely randomized design. Feed conversion ratio was not significantly influenced by VM supplementation. However, the highest feed intake was recorded in broilers fed CF supplemented with 2% VM (T2) while control broilers fed only CF (T1) had the lowest feed consumption. Broiler chickens fed CF supplemented with 2% VM (T2) were recorded with the highest values of final body weight and weight gain compared to T1 group and T4 group, respectively. However, broiler in T2 group had similar values of body weights and weight gains compared to T3. Consequently, 2% level of VM had an optimum result in final weight, weight gain, and feed consumption, while comparable to the other treatments in water consumption, feed conversion ratio, dressing percentage, and carcass weight. Cost and return analysis of the dietary treatments with VM showed a negative effect, since the higher concentration of VM supplementation had the higher cost in production, due to the expensive price of imported vermin or earthworm meal. Keywords: broiler chickens, performance, total confinement, vermi meal

Abstract

In this research, spectral data in UV region (200-400 nm) alongside PCA and SIMCA chemometrics were used to classify two types of honey obtained from different honeybees (Apis dorsata versus Apis mellifera). A total of 200 Durian monofloral honey samples from Apis dorsata and 120 samples for Longan monofloral honey from Apis mellifera were prepared. Therefore, spectral data were recorded based on the following parameters: range of acquisition 200-400 nm, transmittance mode, and interval 1 nm. In addition, the original spectra were transformed using three different algorithms: moving average smoothing with 11 segments, standard normal variate (SNV), and Savitzky-Golay 1st derivative with 11 segments and 2 ordos. The result of PCA using transformed spectra in the range of 250-400 nm explained the possibility of clearly separating Durian and Longan honey along the PC1 axis, with 98% variance, while the SIMCA showed a 100% proper classification rate for all prediction samples. In addition, several important wavelengths were identified alongside high x-loadings values at 270 and 300 nm. These results were closely related to the absorbance of important phenolic compounds in honey, including benzoic, salicylic, and aryl-alyphatic acids. The results demonstrate a probability to establish simple and low-cost honey authentication systems, using UV spectroscopy and chemometrics on free-chemical in sample preparations. Keywords: authentication, Apis dorsata, Apis mellifera, SIMCA, UV spectroscopy

Abstract

Fertilization is needed to support the growth of soybean plants. Nitrogen is a type of fertilizer that is needed by soybeans in considerable amounts. Aplication of nitrogen at different times is able to affect the production and quality of soybean seeds. The purpose of this study was to attain information about the morphology, physiology, and production responses of two soybean varieties to the supply of N. This research was conducted at the Cikabayan Experimental Station, IPB University, Dramaga, Bogor Regency. This study used a completely randomized block design with two factors, namely two soybean varieties consisting of Tanggamus and Biosoy 1, and four combinations of N fertilizer doses that were without N fertilization, fertilized N at planting date, fertilized N at the seed filling phase, and fertilized N at planting date+seed filling phase with two replications. The dosage of urea fertilizer used was 25 kg ha-1, so that the N dosages is obtained 11,5 kg ha-1. The results showed that the application of N fertilizers at planting and during the seed filling phase (N3) was an effective time to increase soybean production.

Abstract

Demand for food products is inevitable, this condition is related to food products as a staple food for the sustainability of human life. In Indonesia, the demand for food depends very much on the needs of the people. The purpose of this study is to analyze food demand in Indonesia which is divided into 4 categories of regions: rich cities, poor cities, rich villages, and poor villages need through research that can be obtained about getting assistance in accordance with the consumption demand of people in Indonesia. The research method used secondary data with panel data types obtained from SUSENAS data. The analytical method used to estimate the demand system was through econometrics demand, namely the QUAIDS model and then the data were processed using the SAS program. The results showed a comparison of the total number of households allocated specifically for food if sorted out, namely poor villages were higher then followed by poor cities, rich cities, and rich villages. When there is a change in income, poor rural households and poor cities when the public still responds by allocating a large part of their budgets to very basic trade such as other food and tobacco, rice, other oils, and household fats in rich villages and rich cities provide more responses to allocating their incomes to the trade in meat, fruits, vegetables, fish, eggs, milk, and processed foods.

Abstract

Ralstonia solanacearum (Smith) is one of soil borne pathogens causes bacterial wilt diseases and R. solanacearum is difficult to control because it has a long survival in the soil and have many hosts alternatives. One alternative to control R. solanacearum and to increase productivity is by using grating with combination of resistant varieties of tomato as a rootstock and high production varieties of tomato as a scion. Several studies on grafting to suppress R. solanacearum were reported. However, study on grafting with combination between resistant tomato varieties (Amelia H7996) and high-production tomato varieties with R. solanacearum infestation and without R. solanacearum infestation on the component of yield and fruit quality is limited. The study aims to analyze the effect of grafting with R. solanacearum infestation to the intensity of bacterial wilt disease, component of yield, and fruit quality with R. solanacearum infestation and without R. solanacearum infestation. The result indicated that the intensity of bacterial wilt disease on grafted tomato did not significantly different from resistant rootstock but significantly different from scion. Infestation of R. solanacearum on grafted tomato can decreased the plant productivity that decreased the component of yield on grafted tomato. R. solanacearum infestation also decreased the fruit quality on diameters and fruit firmness. Nevertheless, R. solanacearum did not affect the Total soluble solid/TSS (°Brix). TSS on grafted tomato indicated that the value is taller than rootstock in the field with R. solanacearum infestation and in the field without R. solanacearum infestation. Keywords: fruit quality, productivity, Rasltonia solanacearum, tomato grafted

Abstract

Rice is a staple food for most Indonesian population. Nowadays, people want staple foods that are not only filling but also do not increase blood sugar concentration (low glycemic index). One of foods that contain higher starch, lower glycemic index, and higher fiber than rice is white corn. The white color of the corn is an advantage because if it is made in grits it can resemble rice. Weakness of white corn is harder than rice. To soften and make it easier to consume, it is coated with an edible packaging made from tapioca. The purposes of this study were to study (1) the quality of dried corn rice from local white corn Anoman 1 variety in edible packaging with packaging thickness of 0.7, 0.9, 1.1, 1.3, and 1.5 mm; (2) the quality of cooked white corn rice produced. The results showed that the thickness of the edible packaging significantly affected (1) the moisture, ash, protein, fat, and carbohydrate contents of dried white corn rice and (2) all parameters of cooked white corn rice (a = 0.05). The best cooked corn rice based on the stickiness test was found in coated dried corn rice with edible packaging with a thickness of 1.5 mm. Characteristics of (1) dried white corn rice contained 11.39% water, 0.21% db ash, 15.23% db protein, 0.53% db fat, 72.64% carbohydrates, 2.11% crude fiber, (2) the quality of cooked of white corn rice were 18.17 g / mm2 stickiness, yellowish color (score 1.1), slightly distinctive aroma of corn (score 2.5), slightly fluffier texture (score 3.4), and rather strong sweet taste (score 2.8). Keywords: edible packaging, local white corn Anoman 1, rice, stickiness, tapioca

Abstract

Rice yield and proper weed control need to be increased through an environmentally friendly agricultural system approach in rainfed land during the dry season by reducing the dosage of synthetic fertilizers. This study aims to determine the effect of different fertilizer applications on rice yield and weed abundance in rainfed land during the dry season. The study used a split-plot design, with the main plot of rice variety, i.e., Situ Bagendit and IR-64, and subplots of fertilizer, namely synthetic fertilizers (N, P, K), organic fertilizers + P60 + ½ dose of synthetic fertilizers, organic fertilizers + PGPR + ½ dose of synthetic fertilizer and organic fertilizer + P60 + PGPR + ½ dose of synthetic fertilizer with three replications. The variables observed were rice yield components, namely panicle length, total empty grain and content per panicle, grain weights per hill, effective plot and hectare, 1000 grain weight, harvest index, and weeds summed dominance ratio (SDR). The synthetic fertilizers and three various organic fertilizers, biological fertilizers, and synthetic fertilizers gave different results on the SDR of weeds. The weeds of Sphenoclea zeynalica and Cyperus difformis showed consistent dominance with higher SDR than other weeds, i.e.,> 15 and > 10, respectively. The application of organic and biological fertilizers with half the recommended dosage of the synthetic fertilizers is equivalent to applying the recommended dosage of synthetic fertilizers on rice yield during the dry season on the rainfed dryland with low rainfall intensity and a low yield of 1.3–1.7 t/ha. Keywords: biological fertilizer, inorganic fertilizer, organic fertilizers, rice, weeds
