Abstract

Porang nanocoating is a food coating that has the potential to be developed and is gaining popularity among the public to extend the shelf life of fruits and vegetables. Porang Nanocoating is a nano-sized edible coating made from porang tuber glucomannan. The addition of essential oils can improve the property of the nanocoating of people as a natural antimicrobial coating. Thyme, cinnamaldehyde and eugenol essential oils are known to have excellent antimicrobial properties. Antimicrobial ability is strongly influenced by the concentration of added essential oil. The purpose of this study was to determine the effect of the type and concentration of essential oils on the physicochemical properties of porang nanocoating. This study used a factorial completely randomized design (CRD) with two factors, namely the type of essential oil treatment including essential oils of thyme, eugenol, cinnamaldehyde. While other treatments are essential oil concentrations, namely 1%, 2%, and 3%. The results of this study indicate that the type of essential oil and its concentration affect the physicochemical properties of the porang nanocoating. The physicochemical properties of porang nanocoating based on the type of essential oil treatment gave the following average values: viscosity 16.67 m.Pa.s. – 17.50 m.Pa.s; degree of acidity (pH) range 6.29 – 6.33; color 13.50 – 13.95; transparency 89.40 – 89.56; has stable emulsion properties or there is no separation of the emulsion and in the microscopic test the oil droplets or bubbles are few While other treatments are essential oil concentrations, namely 1%, 2%, and 3%.

Abstract

The application of coatings from natural materials is currently needed to improve the appearance and maintain quality, so that it can support the green economy, namely increasing the welfare and social equality of the farming community. One of the basic ingredients in the manufacture of coatings from the polysaccharide group is konjac flour. The main problems faced in the development of konjac flour as a coating are that the color is still brown and itchy caused to the high content of calcium oxalate. Treatment with NaCl salt is one of the efforts to improve the quality of konjac flour as a coating material. Immersing konjac in NaCl salt solution repeatedly can reduce calcium oxalate. The reason of the observe became to decide the impact of the concentration and time of immersion of konjac slices into the salt solution of NaCl on the characteristics of the resulting konjac flour. This study used a two-factor randomized design, namely the concentration of NaCl salt solution (5, 10, and 15%) and the second factor was the immersion time (15, 30, and 45 minutes). Each treatment combination was repeated three times. The concentration and time of immersion into the salt solution of NaCl affected on color L*, browning index, water content, solubility, and acidity of konjac flour. The best treatment was soaking time of 30 minutes with NaCl concentration of 15%.

Abstract

Developing countries must, in order to support agriculture, integrate available natural resources and promote management of livestock waste. Therefore, the potential of earthworms to decompose organic waste must be exploit : vermicomposting. Thus earthworm Eudrilus eugeniae was cultured in 4 simples treatments and 6 mixed manure treatments. These treatments are combination or not of manure of cattle, cavies, rabbit and poultry. Each treatment has undergone 3 repetitions. The experiment lasted 12 weeks. pH, numerical productivity of E. eugeniae and biomass of E. eugenia have been determined. The results showed that all treatments containing rabbit manure have a final pH close to 7 (neutral pH) with the exception of MG +MR treatment. Those based on poultry or guinea-pig manure and the control range between 5 and 6.5 and are therefore more acidic. The average density and the earthworm biomass of the MC + MR treatment respectively 2889 ± 333 ind./ m2 and 397.22 ± 234.44 g / m2 are different from other treatments. the manure mixture is a privileged environment for Eudrilus eugeniae. It provides a significant biomass of earthworms that can be used in fish farming or in the diet of monogastric animal feed.

Abstract

This study aims to identify internal and external factors and alternative marketing strategies for Arabica coffee in the Harapan Maju Group, Kintamani, Bangli, Bali, Indonesia. The method in this study is the SWOT analysis technique. The results showed that the internal environmental factors that had the highest score on the strength indicator were having a consistent taste of coffee products, having many variants of coffee products, and human resources influencing the quality and quantity of coffee products produced. The indicators of weakness are erratic yields which affect the ups and downs of sales, promotions that are not maximized, and the lack of knowledge of human resources for digital marketing through social media. Meanwhile, the external environmental factors in the opportunity indicator are the growth in domestic coffee consumption which continues to increase, the development of coffee management technology, and the government's efforts to assist group coffee marketing. The threat indicators are that similar competitors are superior in following market trends quickly, the bargaining position of consumers is getting higher, and there is a lot of imported coffee coming from outside. Eight alternative strategies that the Harapan Maju Group needs to carry out to increase profits include: expanding the marketing network, improving the quality of service to consumers, strengthening cooperation or collaboration with government agencies, improving the quality of human resource management with training, increasing promotional activities with digital media setting competitive prices for the development of globalization, increasing the use of technology in Arabica coffee business management, and streamlining Arabica coffee operational costs

Abstract

Cabbage plants (Brassica oleracea) belong to the Brassicaceae family, is a vegetable that is widely cultivated by farmers in rural Indonesia. In an effort to increase the productivity of purple cabbage it is necessary to carry out soil management. Andisol is one type of soil that is relatively fertile but has a high level of P absorption so it is necessary to add Chicken Manure and TSP Fertilizer. The purpose of this study is to determine the effect of treatment and response from the combination of treatment on the application of chicken manure and TSP fertilizer on the growth and production of purple cabbage plants. The research design used was a group randomized design (RAK) with 2 factors arranged factorially. The first factor is chicken manure fertilizer which consists of 3 levels, namely: K1 = chicken manure fertilizer 10 tons / ha (50 grams / polybag), K2 = chicken manure fertilizer 20 tons / ha ( 100 grams / polybag) and, K3 = chicken manure fertilizer 30 tons / ha ( 150 grams / polybag). The second factor of TSP fertilizer consists of 3 levels, namely: T1 = TSP 200 kg / ha ( 1 gram / polybag), T2 = TSP 300 kg / ha ( 1.5 grams / polybag) and, T3 = TSP 400 kg / ha ( 2 grams / polybag). Treatment of Chicken Manure (K), TSP fertilizer, and Interaction (KxT) had no real effect (P ≥0.05) on the variables of maximum plant height, maxmium leaf count, root length, flower crop diameter and wet weight of crop per plant.

Abstract

Along with the increasing population, people's needs for highly nutritious foods, such as vegetables, are increasing [14] but the available agricultural land, especially in urban areas, is increasingly limited. Vegetable crops that have enough economic value besides cabbage crop, cabbage flowers and broccoli are mustard caisim plants. Mustard caisim plants contain many benefits, the content contained in mustard caisim is protein, fat, carbohydrates, Ca, P, Fe, Vitamin K, Vitamin A, Vitamin 10 B, and Vitamin C. Hydroponic farming systems are one alternative that can answer these problems. The purpose of this study was to determine the effect of nutrient concentration of AB MIX and liquid organic fertilizer broiler chicken eggshells on the growth and yield of mustard caisim plants (Brassica juncea L. Czern. Var. Tosakan) hydroponically. The study method was prepared using Mirosoft Excel 2010 followed by a 5% BNT Test, consisting of five treatments and four repeats so that 20 samples were obtained. Treatment K1 = Nutrition AB-Mix, K2 = AB-Mix + 10cc liquid organic fertilizer, K3 = AB-Mix + 20cc liquid organic fertilizer, K4 = AB-Mix + 30cc, liquid organic fertilizer K5 = AB-Mix + 40cc liquid organic fertilizer. The results showed that the highest economic result weight was obtained from the treatment of ABMix + 10cc liquid organic fertilizer (K2) nutrient concentration which was 73.3 g or an increase of 46.50% when compared to the lowest economic result weight at AB-Mix + 40cc liquid organic fertilizer (K5) nutrient concentration which was only 44.8 g.

Abstract

Bali is one of the grape-producing regions in Indonesia, and grape cultivation is carried out in the North Bali area of Buleleng Regency. Grape growers in Bali began to plant other grape varieties, namely green grapes (Vitis vinifera L. var. Muscat Saint Vallier). This grape variety originates from France and grows successfully in the tropics. Currently, there needs to be more information about the yield potential and quality of green grape varieties. This study aims to determine the productivity and quality of green grapes at several harvest periods and locations. The research was conducted from January 2021 to September 2022 at three sub-district locations: Gerokgak, Kalisada, and Seririt. The research was conducted at six locations, namely Gerokgak 1, Gerokgak 2, Gerokgak 3, Kalisada 1, Kalisada 2, and Seririt. Data collection was carried out during three pruning to harvest periods: January–March, April–June, and July–September. Harvest period and planting location show a significant influence on green grape productivity. Observations on grape productivity in different years showed no significant results, and there was no interaction between location and harvest period. The harvest period for two consecutive years shows that the July–September harvest period gives the best yields. The quality of the yield of green grapes shown in the fruit obrix at both locations at different harvest periods shows that the obrix of this variety remains the same.

Abstract

Entomopathogenic nematodes (EPNs), consisting of genera Steinernema and Heterorhabditis are biological agents proven effective in killing insect pests. Organic rice fields and sandy soil textures are potential areas for exploring the presence of EPNs. This research aims to determine the diversity of genera and populations of entomopathogenic nematodes in organic rice fields in Sleman Regency. The study was conducted on organic rice fields and the UPN "Veteran" Yogyakarta Plant Protection Laboratory from July – August 2023. EPNs were obtained from Prambanan Sleman and Ngemplak Sleman, with six plots as sample units in every location. EPNs were isolated from soil samples by using Tenebri molitor larvae. The Whitehead tray method was used to isolate EPNs from the dead larvae, and the population of EPNs was counted. EPNs were identified based on the symptoms of color changes on the cuticle and morphological characters. The result showed that the cuticles of T. molitor larvae that died were blackish brown in Prambanan and Ngaliyan isolates, referred to Steinernema genera. EPNs were found in Prambanan_6, Ngaliyan_1, and Ngaliyan_2. The highest population of EPNs was on Ngaliyan_1 (38,00 EPNs/ml), and the lowest was on Prambanan_6 (2,13 EPNs/ml). Based on the morphological characters of EPNs, on the Prambanan_4, Ngaliyan_1, and Ngaliyan_2, EPNs were identified as Steinernema spp. The characteristics of Steinernema in the infective juvenile stage found are: slender body, anterior end slightly rounded and fused with the body, cylindrical stoma, no second cuticular sheath, not annulated, and conoid tail.
