Abstract

Compost is an organic fertilizer whose basic ingredients are from weathering plant material or organic waste. However, the community has a few obstacles, namely the need for very large doses of fertilizer which often makes its use difficult. Therefore, efforts need to be made to overcome this problem, namely by making the fertilizer form into a solid form. So a tablet compost printer was made that can determine the capacity of the tool's mold with a press system. Analysis of the data used in this study is a mathematical approach using Microsoft Excel and a statistical approach using ANOVA diversity analysis and further test of Honest Significant Difference (BNJ) level 5%. The results showed that the higher the addition of hydrogel, the lower the dimension value, both weight, height and diameter of the tablet. The capacity of the mold in each treatment was carried out 3 times the average repetition of each treatment at P1 4.41 kg/hour, P2 6.10 kg/hour and P3 6.30 kg/hour the weight of the compost material affects the capacity of the mold, the heavier the material being printed, the higher the capacity of the mold.

Abstract

Moringa or (Moringa oleifera l.) is a very common plant in tropical and subtropical climates. West Nusa Tenggara is one of the areas with a relatively high level of drought, where the dry season is relatively longer than the rainy season. This affects the type and character of plants in the West Nusa Tenggara region in adapting to these climatic conditions. One of them is the moringa plant which easily adapts to hot weather and altitude above sea level. Moringa is a plant with various benefits, such as food, medicine, cosmetics, and others. The purpose of this study was to analyze the effect of different drying temperatures on the chemical and physical properties of dried Moringa leaves using a tray dryer. This study used a 1-factor Completely Randomized Design (CRD) with three temperature treatments for 2 hours of drying with three replications. The temperature treatments in the study were: 45°C, 50°C and 55°C for 2 hours. The research results from the analysis of the chemical properties of dried moringa leaves from the three temperature treatments can be seen that the effective temperature treatment at 55°C, namely: water content (21.67%), ash content (0.51%), protein content (19.43%). The results of the analysis of the physical properties of the color test using the Colorimeter application showed that the highest value was at 50°C with a value of (77.93) and the organoleptic test of the panelist's preference level for the texture of dried Moringa leaves was seen at 55°C with a value of (4.08).

Abstract

One alternative energy source for making organic waste which can be renewed is pineapple waste and tofu waste. Biogas produced from these two materials is environmentally friendly so it does not disturb the environment. The purpose of this research was to determine the changes in temperature and pH that occurred during the formation of pressure and volume of biogas. The method used in this study was an experimental method using a completely randomized design (CRD). There are 4 treatments in this study, namely T1: pineapple waste; T2 : tofu liquid waste; T3 : addition of tofu solid waste; and T4 : addition of tofu liquid waste and tofu solid waste. The measurement results were then analyzed using analysis of variance (ANOVA). If significantly different results were found, a further test was carried out with BNJ. The results showed that the addition of tofu waste significantly affected the temperature, pH, pressure and volume of bioga. The average temperature for each treatment was 28oC, while the highest pH was 8.55. The highest pressure calculation results were found at T4 of 109.42 N/m2, while for the highest volume it was found at T4 of 0.000016642m3. Based on the description above, it can be concluded that the addition of tofu waste has a significant effect on the formation of biogas

Abstract

The main source of energy for humans is natural resources derived from fossils. Scarcity and rising oil prices will continue to occur due to its non-renewable nature. This must be immediately balanced with the provision of alternative energy sources that are renewable, abundant and cheap so that they are affordable by the wider community. The use of briquettes is based on the increasing price of petroleum in the global market. Charcoal briquettes are charcoal that is further processed into briquettes (special and more attractive appearance) that can be used for daily purposes. This study aims to determine the best raw materials in making quality briquettes. The method used in this research is an experimental method with experiments in the laboratory. The design used is a completely randomised design (CRD) consisting of 5 treatments as follows, P1: 100% corn cob, P2: 75% corn cob + 25% rice husk, P3: 50% corn cob + 50% rice husk, P4: 25% corn cob +75% rice husk and P5: 100% rice husk. Observation data were analysed using Anova (analysis of variance) at the 5% level. If there is a significant difference, then it is continued with the honest real difference test (BNJ) at the real level of 5%.  The lowest value of water content was P5 which was 47.44%, in the stability of the smallest shape change was P1 4.0%, the least particle loss was P1 0.35% and the longest burning time was P3 at 113 minutes. Based on the research results, the best treatment is P3 where the moisture content value is 47.64%, with particle loss of 0.77%, and the longest burning time is 113 minutes.

Abstract

Compost can be defined as the result of the decomposition of organic matter, while composting is a process in which organic matter is decomposed biologically, especially by microbes that utilize organic matter as an energy source. The effect of adding hydrogel to compost is a soil conditioner that focuses on water and nutrient retention so that it can reduce the use of irrigation water and increase the ability of plants to grow. The application of hydrogel and compost can improve physical properties such as bulk density, porosity, number of pores, water content of field capacity, water content of harvesting wilting point, available water, chemical properties, and soil biology. This study aims to determine the composition of the addition of hydrogel to tablet compost made from bio-slurry which is most appropriate for the moisture content and hardness of tablet compost. The method used in this research is experimental with direct testing in the laboratory. The results of the study The higher the addition of hydrogel, the higher the water content because there is still bound water trapped in the hydrogel and the best tablet compost or the highest water content was obtained in the P5 treatment, which was 18.35%, and the addition of hydrogel caused the tablet compost to become soft and elastic. so hardness is easier to destroy. The results of the analysis show that the best tablet compost hardness value is found at P0 of 97.0000 Newton

Abstract

The Robusta coffee plant (Coffea canephora) is included in the Rubiaceae family and the Coffea genus. The problem in breeding Robusta coffee plants is that Robusta coffee seeds cannot be developed generatively because of the type of cross-pollination, so they must be propagated vegetatively by cuttings, namely slow root growth and rooting. weak so shoot formation is slow. To overcome this problem, liquid NPK fertilizer (24:20:05) was used with the aim of producing optimal cutting growth. The aim of this research was to determine the effect of the dose and frequency of application of liquid NPK fertilizer (24:20:05) on the growth of Robusta coffee cuttings. The method used was a factorial Randomized Block Design (RAK) consisting of 2 factors and 3 replications. Factor 1 consists of F0: 0 ml/polybag, F1 (25 ml/polybag), F2 (50 ml/polybag), F3 (75 ml/polybag), F4 (100 ml/polybag). The second factor is the frequency of fertilization (M) which consists of M1: Application once a week M2: Application once every 2 weeks M3: Application once every 3 weeks. The research results showed that there was an interaction between the dose of liquid NPK fertilizer and the frequency of fertilization on Robusta coffee cuttings (1) which had a very significant influence on the observed variables of stem diameter, number of branches and leaf area. (2) Giving a dose of liquid NPK fertilizer to Robusta coffee plant cuttings has a very real influence on all variables. (3) The effect of fertilization frequency on Robusta coffee plant cuttings has a very real influence on the variables of stem diameter and number of branches.
