Abstract

This literature study aims to find out and explore the potential of local tubers as nutritious instant food. Instant food is food that is packaged, easy to prepare, practical, or treated only. The food is generally produced by the food processing industry with high technology and provides a variety of additives to preserve and provide flavor to the product. Nowadays people's consumption patterns are required to be fast-paced due to increasingly dynamic work, so instant food is the solution, but not all instant foods are good for health. Tubers are one of the commodities that have the potential to be developed as instant food, in addition to being a substitute for rice to support food diversification programs. Food diversification is a way to organize or create a diversity of commodities consumed, with the program of diversification of food, it is expected that people's consumption patterns not only depend on one type of food but also have other alternatives.

Abstract

Households have become one of the sources of waste and their utilization so far is also fairly minimal. Household waste tends to end up in landfills when it can be processed into materials of economic value. Waste ingredients such as vegetable waste or fruit peels can be processed into a multipurpose eco-enzyme liquid. Making eco-enzyme is very simple and can be done by anyone. Eco-enzyme is an organic compound in the form of a complex solution resulting from the fermentation process of kitchen waste materials in the form of fruit peels and vegetable waste. The term Eco-enzyme was initiated by Dr. Rosukon Poompanvong, a founder of the Organic Agriculture Association, Thailand who has researched since the 1980s. A Naturopathy researcher from Penang, Malaysia, Dr. Joean Oon later introduced the term more broadly. The use of eco-enzyme in its development is expanding, so it is not uncommon to be referred to as a multipurpose liquid. This liquid in the environmental field has been commonly used in liquid waste treatment, lake water purification, improved air, and soil quality. Utilization in the field of health is usually used to prevent hair loss, hives, and hand sanitizer. Eco-enzyme is also commonly used as fertilizer and biopesticide. The creation of eco-enzyme not only helps reduce waste disposal to landfills but also becomes an alternative to reducing the use of synthetic chemicals that are harmful to human health and the environment. Awareness of household waste processing into eco-enzyme is also a step in the effort to realize zero waste at the household level.

Abstract

White oyster mushroom chips are products that are in great demand today. In addition to delicious taste, it also contains nutrients that are beneficial for health. The quality of the chips is largely determined by the addition of the type and amount of flour added. The purpose of this study was to determine the effect of the ratio of wheat flour and tapioca flour on the characteristics of white oyster mushroom chips. This study used a completely randomized design with three replications. The treatments tested were the ratio of wheat flour and tapioca flour with levels: (90:10) %, (80:20) %, (70:30) %, (60:40) %, (50:50) %. Comparison of wheat flour and tapioca flour only had a significant effect on the subjective test of water content and carbohydrate content of white oyster mushroom chips. The objective test had a significant effect on the taste, texture, and overall acceptance of white oyster mushroom chips. Comparison of flour and tapioca flour 60: 40% produces white oyster mushroom chips with the best organoleptic score.

Abstract

Waste is unwanted residual material after the end of a process. The problem of waste has become a global issue that is a threat to the environment if it is not properly managed. Based on data from the Klungkung Regency Environmental Service in 2019, from four sub-districts in Klungkung Regency namely Dawan, Banjarangkan, Klungkung, and Nusa Penida, the volume of waste per day is more than 115,000 kg/person/day from a population of more than 230 thousand people, when compared production average waste production weighing 0.5 kg per person/day. Meanwhile, in terms of composition, the highest amount of waste is organic waste (68%), dust, rock and the like (8%), glass and plastic bottles 7%, followed by sheet plastic 5% and plastic 4%. The results of the analysis and depiction on the graph of the survey results were 4 (four) villages that had a high percentage of segregation, namely Semarapura Kauh Village (83.33%), followed by Semarapura Tengah (82.23%), followed by Semarapura Kangin Village (78.87. %) and Semarapura Kaja (75.21%). The results of this study prove that two locations have a very low level of sorting waste (less than 50%), namely Jempriring street in Semarapura Klod (47.61%), Rama street (42.11%), and Puputan street in Semarapura Kangin (44.73%). From this research, it can be concluded that public awareness of sorting waste in the two locations is still lacking.

Abstract

Tomato is an important vegetable crop and has been widely cultivated as a garden plant or commercially. The purpose of this study was to measure the effectiveness of organic fertilizer based on coal and cow dung based on several tomato varieties. This study used a factorial randomized design with two factors, namely the type of fertilizer consisting of "Saputra" coal fertilizer (BB), "Bio Alam Asri" manure (BA) and without organic fertilizer (B0); and the other factor is the tomato variety factor (V), namely Servo F1 (VS), Gustavi F1(VG), and Fortuna 23 (VF). Based on the results of the study, it was found that the treatment of BB and BA, in general, had a significant effect on vegetative growth and generative yields including fruit quality in the three tomato varieties tested. The highest number and fresh weight of tomatoes per plant were obtained in the treatment of BB, namely 44.00 fruits and 3.00 kg, higher than BA fertilizer, namely 39.11 fruit and 2.62 kg, and B0 namely 34.00 pieces and 2.20 kg. The highest number and fresh weight of tomatoes per plant were obtained in VS varieties, namely, 42.33 fruits and 2.74 kg, followed by VG varieties at 40.11 fruits and 2.71 kg and the lowest was VF at 34.67 fruit and 2.38 kg. The highest vitamin C content of fresh fruit was obtained in the BB treatment, which was an average of 36.75 mg/100g, higher than the treatment with BA fertilizer and B0, which were 32.81 mg/100g and 31.07mg/100g.

Abstract

This study aims to determine the effect of the length of cuttings and the dose of rabbit manure on the growth and yield of purple sweet potato, which was carried out in Banjar Uma Kepuh, Buduk Village, Mengwi District, Badung Regency, Bali Province. The implementation time of the research starts from March - July 2021. The design used in this experimental design is a Randomized Block Design (RDB). The first factor was the length of the cuttings: S1 (40 cm), S2 (50 cm), and S3 (60 cm). The second factor was the dose of rabbit manure K0 (without fertilizer), K1 (5 tons/ha), and K2 (10 tons/ha). Observation variables included stem length per plant, number of shoots per plant, number of leaves per plant, tuber diameter per plant, number of tubers per plant, fresh weight of tuber per plant, fresh weight of tuber per plant, the weight of oven tuber per plant, dry weight number of ovens per plant and harvest index. The results showed that the length of the cuttings had a significant to a very significant effect on the observed variables except for the largest tuber diameter per plant, tuber fresh weight per plant, and tuber fresh weight per plant had no significant effect. The results of this study indicate that the best cutting length is 50 cm. The dose treatment of rabbit manure had a significant to a very significant effect on the observed variables except for the number of tubers per plant, which had no significant effect. The kind of dose of rabbit manure that gives the best economic results is without rabbit manure. There was an interaction between the length of cuttings and the dose of rabbit manure which had a very significant effect on the observed variables except for the number of shoots per plant, the number of tubers per plant, and fresh weight per plant. The best combination obtained in this study was treatment with cuttings length of 50cm and without a dose of rabbit manure.

Abstract

Availability of forage fodder both in quality and quantity is an important factor in determining the success of the ruminant livestock business. The purpose of this study was to determine the effect of plant spacing and fertilizer dosage on the production of Taiwan Elephant Grass (Pennisetum purpureum cv. Taiwan) at different cuts. The field research was conducted using a Randomized Block Design (RAK) with a 3 x 4 factorial pattern, where three treatments were plant spacing (Factor A), and four treatments were dosed with fertilizer (Factor B). Each treatment combination was repeated three times so that there were 36 plots of treatment combinations. (Factor A) which consists of 3 types of spacing, namely (J1 ) 30 x 50 cm, (J2 ) 40 x 50 cm, (J3 ) 50 x 50 cm and 4 doses of fertilizer treatment (Factor B) which consists of 4 doses of fertilizer namely without fertilizer (D0), 10 tons//ha (D1), 20 tons/ha (D2), 30 tons/ha (D3). The variables measured were total plant production, botanical composition, and air dry weight (DW). Based on the study results, the spacing treatment had a significant effect (P<0.05) on the total production of Taiwan Elephant Grass stems at the first cutting. In contrast, the total plant weight, % stem, % leaf, air-dry weight (DW) had no significant effect (P> 0.05) on all observed variables. All the variables observed at the second and third cuts were not significantly different (P>0.05), but the total crop production at the third cut was higher than the second cut. The type of fertilizer had no significant effect (P>0.05) on all observed variables such as total plant weight, % stem, % leaf, total stem weight, total leaf weight.
