Abstract

Biogas production by fermentation is a source of energy obtained from organic waste, one of which is waste from the tofu and tempeh industry. The aim of this study was to analyze the biogas content of tau waste by adding urea. The research method uses an experimental method with a Completely Randomized Design. There were four treatments, namely T1: 7 kg of tofu waste, T2: addition of 7 kg of tofu waste + 1.4 kg of urea starter, T3: addition of tofu waste + 2.8 kg of urea starter, and T4: addition of 7 kg of tofu waste + urea starter as much as 4.2 kg. Each treatment was repeated 3 times to obtain 12 experimental units. The statistical test results show that the biogas content, in this case carbon dioxide and methane gas, with the highest measurement results found in T1 was 3819.17 ppm, and methane gas was 558.08 mol.

Abstract

Cucumber has the potential to be developed because it has high economic value and promising market opportunities. The main obstacle in increasing cucumber plant production is the physical and chemical conditions of the soil. The addition of nutrients can be done using organic fertilizers. The purpose of the study was to determine the effect of the concentration of wovi liquid fertilizer and goat manure on the yield of Monas variety cucumber plants. This research was conducted in Kotasan Village, Hamlet V-VI B, Galang District, Deli Serdang Regency, with an altitude of 12 meters above sea level. This research was conducted from March to July 2024. This study used a factorial randomized block design consisting of two factors, namely: Factor 1, wovi liquid fertilizer (W) consists of 5 levels, namely: W0 = control, W1 = Dose of liquid fertilizer 5 ml / liter, W2 = Dose of liquid fertilizer 10 ml / liter, W3 = Dose of liquid fertilizer 15 ml / liter, W4 = Dose of liquid fertilizer 20 ml / liter. The second factor of goat manure (O) consists of 2 levels, namely O1 = Dosage of goat manure 10 tons/ha and O2 = Dosage of goat manure 20 tons/ha. The results of the study showed that the use of goat manure and Wovi fertilizer had no significant effect on the number of fruits, fruit length and fruit weight.

Abstract

The low production of white mustard greens in Indonesia is due to the lack of organic matter content in the soil needed by plants. The addition of optimal organic matter, one of which is the utilization of bioconversion technology of organic waste of black soldier fly larvae. The purpose of this study was to determine the effect of kasgotchar and NPK applications on the production of white mustard greens (Brassica pekinensis L.) variety Masita140. This study used a Factorial Randomized Block Design with 2 factors: Factor l, namely the provision of Biochar kasgot fertilizer (K) with 3 levels, namely: K0 = Control (0 kg / plot), K1 = 10 tons / ha (1 kg / plot), K2 = 20 tons / ha (2 kg / plot). Factor 2, namely the provision of NPK fertilizer 16: 16: 16 (P) with 4 levels, namely: N0 = Control (0 kg / plot), N1 = 100 kg / ha (0.01 kg / plot), N2 = 200 kg / ha (0.02 kg / plot), N3 = 300 kg / ha (0.03 kg / plot). The parameters observed in this study include Fresh Weight per crop, fresh weight per plot and production per hectare (tons). The results of the study showed that the use of kasgotchar and NPK fertilizers did not differ significantly on Fresh Weight per crop, fresh weight per plot and fresh weight per hectare. The best treatment was the K2N3 treatment (kasgotchar with a dose of 2 tons / ha, and NPK with a dose of 300 kg / ha

Abstract

Our research focuses on enhancing the potential of pumpkin seed waste extract as a sustainable corrosion inhibitor for metal (Fe) in 1 M HCl solution. Phytochemical screening and antioxidant activity were identified. Various investigative methodologies including experimental techniques such as Potentiodynamic Polarization (PDP) were used to evaluate the effectiveness of these pumpkin seed waste extract inhibitors in inhibiting corrosion. Electrochemical results showed that the effectiveness of the inhibitor was concentration dependent here reaching 83.11% at 3000 g/L pumpkin seed waste extract inhibitor. The PDP showed that the mixed inhibition control effectively retarded the corrosion of the metal. Furthermore, the adsorption behavior of the pumpkin seed waste extract inhibitor onto the metal follows the Langmuir isotherm model with physisorption properties. The adsorption mechanism of the inhibitor on the metal surface successfully formed a protective film on the metal surface thereby reducing the corrosion rate.

Abstract

This study aims to examine the characteristics of Cissus Sicyoides natural fibers extracted by two different methods, namely mechanical and boiling methods, and their application as reinforcing materials for epoxy resin-based composites. The characteristic of fibers was tested through physical and chemical properties, and fiber morphology, including tensile tests, FTIR, SEM and chemical composition. The results showed that the mechanical method produced fibers with higher tensile strength (431.41 MPa) and rougher surface structures, which support better mechanical bonding in the composite matrix. Meanwhile, the boiling method produced fibers with higher cellulose content (23.05%) and a cleaner and tidier surface. FTIR tests confirmed the presence of hydroxyl and carbonyl groups in both samples, while SEM results showed significant presence in the surface morphology and fiber cross-section. Composites made with fibers from the mechanical method had higher tensile strength (28.97 MPa) compared to composites from the boiling method (9.42 MPa). Overall, Cissus Sicyoides fiber has the potential as a composite reinforcing material with a mechanical extraction method that is superior in producing better mechanical performance. The findings of this study add to the use of local natural fibers as an alternative, ecologically friendly composite reinforcement for lightweight buildings.

Abstract

Illegal Gold Mining in several areas of West Nusa Tenggara, particularly in Sumbawa, has had negative impacts on the environment, such as natural damage and environmental pollution, including water contamination with mercury. This study aims to determine the effect of variations in absorbents from coconut shell, candlenut shell, and bidara wood on the physical and chemical characteristics of mining wastewater. The method used in this research is experimental, involving testing with filtration equipment. This study employs three treatments (absorbent variations) and three repetitions for each treatment. The results indicate that the use of activated carbon from coconut shell, candlenut shell, and bidara wood can affect the color, TDS, pH, and mercury content in mining wastewater. Among the three variations of activated carbon, the treatment with bidara wood activated carbon proved to be the most effective in clarifying water color with a score of 1.4 (very clear), reducing TDS by 3570 ppm, improving pH to 7.63, and decreasing mercury content in the water to 1.39 µg/L.

Abstract

This research aims to design and build an alcohol distillation machine made from duku fruit using a refrigerator cooling system and a box cooler as a condenser. The distillation machine utilizes a heating furnace to produce ethanol vapor from fermentation, which is then condensed in a cooled box cooler. Tests were conducted with variations in furnace temperature (110°C, 125°C, 140°C, and 155°C). The results show that the higher the heating temperature, the volume of distillate produced increases, from ±132 ml to ±330 ml. However, the ethanol content remained relatively low (10-20%) due to the low initial ethanol content of the fermentation and only one-stage distillation. These results show that the design of the device can function well on a laboratory scale, although further distillation is needed to increase the ethanol content. This research is expected to be the first step in developing a small-scale ethanol distillation device that is efficient and easy to implement.

Abstract

The study aimed to obtain the interaction of NPK and ecoenzymes on the growth and yield of soybean plants, thus reducing the use of NPK.  The experiment was conducted on dry land in Kuranji-Padang, at an altitude of 10 m above sea level, from May to August 2023.  The study used a factorial completely randomized design (CRD) (4 x 3) with 3 replications.  The first factor was ecoenzyme consisting of 3 levels; 0, 5, 10, and 15 ml/l water.  The second factor is NPK which consists of 3 levels, namely; 100, 200, and 250 kg/ha.  Parameters observed; plant height, number of primary branches, number of leaves, number of effective root nodules, number of pods per plant, number of empty pods, pod length, 100 seed weight, and dry weight of seeds/plot.  Data were investigated for variance, if the effect was significant, it was followed by the 5% level of Honest Real Difference (BNJ) test.  Data were analyzed using Statistix software ver. 8. The results showed a significant interaction between NPK 200 kg/ha with 0 ml/l ecoenzyme on the growth of soybean plant height. NPK at 200 kg/ha significantly affected the number of primary branches, the number of pods, and the dry weight of seeds/plot. Ecoenzyme was not significant on the number of primary branches, number of leaves, number of root nodules, or pod length of soybean plants.  Optimization of ecoenzymes needs to be done by reducing the rate of NPK fertilizer given.
