Abstract

Climate change affects the agricultural sector, which has an impact on droughts or floods. Ecological agriculture is expected to be an adaptation method for reducing losses due to climate change. This study aims to describe the characteristics of farmers, ecological rice cultivation practices, and the relationship between the two parameters. The research in Kendayakan Village, Terisi District, Indramayu Regency, involved 60 farmers surveyed using accidental sampling techniques in February 2022. The data collected include farmer characteristics (age, education, land area, land ownership status), length of farming, sources of farming knowledge, participation in groups, and rice cultivation practices. Data on the application level of ecological agricultural practices were analyzed descriptively and tested usin the Spearman Rank correlation between farmer characteristic variables and rice cultivation practices. The results showed that farmers were of productive age, with a low level of formal education but experienced and active in local organizations. The level of application of farmers' ecological agriculture is moderate. The return of straw, tillage, and control of plant pests are the components of cultivation that are least following the principles of ecological agriculture. Internal factors of farmers that correlate with the components of ecological rice cultivation are age, education, length of farming, source of farming knowledge, and land ownership status. Keywords: climate change, paddy field, paddy’s straw return

Abstract

Shallot productivity relies on diverse environmental conditions, including soil fertility. Compost is an organic material that is crucial for the improvement of soil health and fertility. Compost amendment could be employed on shallot to improve its growth and productivity. This study aims to investigate the effect of 4 different composts amendments, processed with 4 different bioactivators, on the shallot growth (Bima–Brebes variety), the dynamic of culturable microbes, and nutrient content on the growth medium inside the polybag. Treatments include a mature compost processed with no biactivators (K0), and with the bioactivator Bioaktimo (K1), Beyonic Startmik (K2), indigenous (K3), and the mixed of K1, K2, and K3 (K4). Measured parameters on shallot growth include plant height, number of leaves, stem diameter, wet and dry weights of shallot bulb, root, and above-ground biomass, and chlorophyll content. In addition, physical, chemical, and biological characteristics of the initial planting medium on the polybag were determined. The result showed that compost amendment significantly increased all parameters tested, except chlorophyll content, when compared to the control and the treatment with 100% chemical fertilizer. The best shallot growth was found in the treatment with soil planting media of 75% Soil + 25% Compost K4 (TK5). Keywords: organic fertilizer, bioactivator, shallot

Abstract

Gotu kola is one of the medicinal plants that is widely used because of its various nutritional content. In general, the cultivation only uses inorganic fertilizers, which have long-term effects that are not good for the environment. The use of organic fertilizers is an effort to produce high-standard products. Rabbit urine liquid organic fertilizer and goat manure are alternative types of fertilizer that can be given. Therefore, this study aimed to determine the response of giving liquid organic fertilizer of rabbit urine and goat manure and their interaction with the growth and yield. The study used a Factorial Randomized Block Design (RBD). The first factor was rabbit urine liquid organic fertilizer (LOF) with a concentration of 0, 2, and 4%. The second factor was goat manure with doses of 0, 37, and 75 g/polybag. The results showed that applying rabbit urine (LOF) and goat manure increased the growth and yield of gotu kola. Application of 2% rabbit urine LOF significantly increased stalk length compared to controls. Gotu kola plants given 37 g/polybag of goat manure produced stolons that were significantly longer than those treated with goat manure 75 g/polybag and had significantly heavier roots than other treatments. The interaction of rabbit urine LOF and goat manure application had no significant effect on all observed variables. Keywords: goat manure, gotu kola, liquid organic fertilizer, rabbit urine

Abstract

Yogurt is a dairy product that is processed into a fermented drink using lactic acid bacteria. Smoothies are drinks made from fruit or vegetables containing milk, yogurt, or honey. Strawberry Rosella Yogurt Smoothie is yogurt that has been processed by reducing the water content and adding rosella flower extract and strawberry jam. Before being marketed, these products need to be tested for safety and market opportunities. This study aims to analyze the physicochemical characteristics, microbiology, and market tests of strawberry rosella yogurt smoothies in adolescents and adults in Bogor. The physicochemical characteristics tested included pH, water activity (aw), viscosity, and total titrated acid. The microbiological parameters tested were total lactic acid bacteria and Salmonella sp. The market parameters tested include analysis of consumer perceptions and preferences and their correlation with yogurt consumption patterns. The market test was carried out using 100 respondents consisting of 50 students from SMAN 1 Bogor and 50 students from IPB University. The results showed that the physical properties (pH, water activity, viscosity, and total lactic acid) fulfilled the SNI yogurt quality requirements. The chemical properties or nutritional content and microbiological properties of yoghurt smoothies have met the requirements for yoghurt quality standards based on SNI. The results showed that respondents had good perceptions and preferences on the attributes of smoothie yogurt. Consumer preferences regarding the appearance of the packaging in general, color, ingredient content, packaging information, and appearance of the contents of the yogurt are generally positively correlated with the price range of yogurt that consumers buy. Strawberry Rosella Yoghurt Smoothie is safe for consumption and can be marketed. Keywords: consumer perception, consumer preferences, microbiology, physicochemistry, yogurt smoothies

Abstract

The soybean agribusiness institutions have important roles to support the increased soybean production in Central Java. The purpose of this study was to analyze the levels of performance and importance of farmers in the institutional performance of soybean agribusiness in Central Java. This research uses descriptive analytical method, with the technical implementation of research using survey methods. This research was conducted on September - December 2022 with a sampling technique using a purposive sampling on 110 respondent farmers. Data analysis carried out in this research is Importance and Performance Analysis (IPA). IPA is used to compare the level of importance of soybean farmers with their levels of performances. Before being analyzed using IPA, each attribute was tested for validity and reliability, and from the test results it was found that each attribute was declared valid and reliable. The results of the analysis show that one of the attributes that is included in quadrant I and needs to be a priority for improvement is the need to determine the Harga Pokok Produksi (HPP) for soybeans by the government and the need to increase the subsidized fertilizer program. Attributes that fall into quadrant II and whose performances must be maintained include the existence of collector traders, the existence of a soybean seed assistance program, and the availability of quality soybean seeds. Attributes that are included in quadrant III and are the second priority for repairing and improvement are the need for storage granaries, partnerships with companies, and the easy access to financing services. Meanwhile, the attributes that enter quadrant IV and can be ignored are the availabilities of water, labor, and farming infrastructure. Keywords: importance and performance analysis, importance farmers, performance farmers, soybeans

Abstract

Traditional nata de coco fermentation often results in inconsistent nata thickness. From the producer's perspective, thin nata sheets are detrimental because most fermentation media will be wasted. The main cause of this condition may be that the microbial population in the starter culture is different in each batch. It is necessary to observe the cultured microbial community on various qualities of available thick and thin nata to design a better nata de coco starter culture. This study showed thick nata had more Komagataeibacter intermedius bacteria (pellicle forming) than thin nata. In traditional nata fermentation, K. intermedius always coexists with other microbes from the bacteria and yeast groups. Random Amplified Polymorphic DNA (RAPD) analysis indicated that the genetic diversity of bacteria was higher than that of the yeast group. Keywords: dendrogram of relationship, fermented food, microbial genetic diversity, nata de coco

Abstract

Expanding agricultural land by using sloping dry land can be detrimental to the environment due to soil erosion and degradation. However, cover crops can be one of the technologies applied to reduce these risks. Arachis pintoi is one of cover crops that can be used as bio mulch on agricultural land. The study aimed to evaluate the effect of A. pintoi bio mulch on soil nutrient contents and maize plant growth at different slopes. A nested randomized block design was used in the study. Two levels of land used as the main factor and the type of mulch consisting of five levels (without mulch with weeding, without mulch without weeding, silver-black plastic mulch, straw mulch, and A. pintoi bio mulch) were used as the second factor. The results showed that A. pintoi bio mulch significantly increased the P content of the soil and could potentially increase several other macronutrients, especially C-organic, N, and Ca. The use of A. pintoi bio mulch with a cover technique that was left to cover the entire soil surface suppressed the growth and yield of maize plants compared to the control treatment. Keywords: cover crops, mulch, ornamental peanut, soil fertility, rice straw

Abstract

Standardization of the quality of the depolarized katuk pellet production process as a feed additive is very important to maintain product quality. The production process requires dry katuk leaves (DKK) as raw materials which are then processed into depolarized katuk leaves (DKD), and continues in the pelleting process to become depolarized katuk pellets (PKD). Quality standard can be done by measuring the parameters of nutritional value and also the yield of methanol extract. Nutritional values were obtained from the results of proximate analysis, namely the percentage of dry matter, ash content, crude protein, crude fiber, crude fat, beta-N, calcium, phosphorus, and gross energy (Cal/g). Mean while, the yield of methanol extract was obtained by maceration using methanol solvent. This study aims to evaluate the nutritional value and yield of crude methanol extract of katuk leaves (DKK, DKD, PKD) which can be used as a quality assurance standard for the depolarized katuk pellet production process. In general, the nutritional value of DKD and PKD had the same value as that of DKK, except for calcium which was quite high (P<0.05) in DKD and PKD, and the percentage of crude fiber was lower (P<0.05) in PKD compared to DKK and DKD. The percentage of crude fat in pellets (PKD) was higher (P<0.05) when compared to DKK and DKD. The yield of methanol extract was very high (P<0.05) in DKK, compared to DKD and PKD. The nutritional parameters and the yield of the katuk leaf extract can be used as quality assurance standards for the depolarized katuk pellet production process. Keywords: depolarization, katuk, methanol, nutrition, pellet

Abstract

This study aims to determinethe physical properties and mechanical properties at axial (base, middle, and top) and radial (near the pith, middle, and near the bark) positions, as well as the relationship between the specific gravity and mechanical properties of Acacia aulacocarpa wood. Three 27-year-old trees planted at KHDTK Wanagama wereused. Wood physical and mechanical propertieswere tested per British Standard 373:1957. The statistical analysis used was a two-way ANOVA and a follow-up test of Tukey HSD. The results showed that the average moisture content was 98.95%; the green and air-dry sepesific gravity were 0.58 and 0.61. Radial, tangential, and longitudinal shrinkage from green to oven-dry conditions (total shrinkage) were 2.02%, 5.09%, and 0.33%. The tangential/radial (T/R) ratio was 2.80%. The static bending strength of stress at proportion limit, MoE, and MoR were 498.13 kg/cm2, 116.16x1000 kg/cm2, and 1043.68 kg/cm2, respectively. The compressive strength parallel to the grain and perpendicular to the grain were 596.05 kg/cm2 and 227.25 kg/cm2, respectively. The results of the variance analysis showed that the radial position factor has a significant effect on green moisture content, green and air-dry specificgravity, total radial shrinkage, T/R ratio, static bending strength at stress of proportion limit, MoE, MoR, compressive strength parallel to the grain, and compressive strength perpendicular to the grain. However, the axial position factor did not show any significant differences in the physical and mechanical properties of the wood. Furthermore, air-dry specific gravity has a significant moderate to high positive correlation with all mechanical properties. Keywords: Acacia aulacocarpa, physical properties, mechanical properties, axial position, radial position

Abstract

Genetic improvement through intensive selection in broilers for economically important traits such as body weight, growth rate, feed efficiency, and carcass quality plays a role in increasing the productivity and efficiency of the broiler industry. Good maintenance management is needed by paying attention to the quantity and quality of feed as well as comfortable and controlled environmental conditions. The environmental factor that is often the focus of attention is the temperature of milieu. During the brooding period aged 0‒21 days, the Day Old Chick cannot regulate its body temperature perfectly and still influenced by ambient temperature. Therefore, it is necessary to study the effect of brooding temperature on the performance of broiler at PT New Hope Indonesia's customers, to find the problems in regulating brooding temperatures along with solutions, evaluations, and improvement plans. Observations were made for 21 days in a semi-closed house with a population of 22,000 Cobb strain broiler. The research method used is data recording observation. The primary data were average brooding temperature for 21 days, depletion rate, feed consumption, body weight, feed conversion ratio (FCR), and production index. There was a deviation in body weight and FCR at the age of 11‒14 days due to the restriction of the heater until the age of 14 days and the wind speed at night which was more than 0.3 ms-1. With the corrective action of wind speed regulation, an effective temperature close to the thermoneutral zone and optimal production performance was obtained until the end of the brooding period. Keywords: body weight, broiler, brooding, feed conversion ratio, temperature
