Abstract

Lettuce, which is also known by the scientific name Lactuca sativa L, is a promising horticultural crop and has high economic value. This plant is rich in minerals, vitamins, antioxidants, potassium, iron, folate, carotene, vitamin C and vitamin E. In growing lettuce hydroponically, the Deep Flow Technique (DFT) method has proven to be effective. This research used a Randomized Block Design (RAK) to test the effect of giving white and blue LED spectrum to lettuce plants. There were four treatments tested: P1 (no LED), P2 (1:3 white and blue LED), P3 (1:1 white and blue LED), and P4 (3:1 white and blue LED). Each treatment was repeated five times, with two sample plants in each repetition, so that there were a total of 40 sample plants. The parameters involve plant height, number of leaves, root length, root weight, leaf color, antioxidant content, consumption weight, leaf width, stem diameter, and electricity consumption during harvest. Measurements were carried out every week for five weeks. The results showed that LED lights had a significant effect on the number of leaves, stem diameter, root weight and consumption weight, but did not have a significant effect on plant height, leaf width, root length, antioxidant content and leaf color. Based on this research, it can be concluded that treatment 4 (white and blue LED 3:1) gave the best results, with the number of leaves reaching 27.4 pieces, root length 18.95 cm, root weight 23.2 g, consumption weight 109 g, stem diameter 8.2 mm, and antioxidant content of 42.39% inhibition.

Abstract

Physiographically, the research area is included in the South Sumatra Basin, precisely in the Muara Enim Formation, a coal-bearing formation. In this study, secondary data is used in the form of LAS file data from recording well logging data as many as 7 wells which are then processed using WellCAD 5.5 software to obtain log sheet results, namely gamma ray logs and density logs which are then interpreted for subsurface lithology by reading the log curve deflection, from the results of reading the log curve, the lithology in the research area is obtained in the form of claystone, siltstone, carbonaceous claystone, and coal. Coal is characterized by low gamma ray log response (<10 CPS) and high density log response (>900 CPS). To determine the distribution of coal seams in the study area, structural correlation and stratigraphic correlation of coal seams on strike (northwest - southeast) and cross strike (southwest - northeast) were found to be 1 coal seam, namely seam A. Seam A experienced splitting into seam A1 and seam A2 due to structural influence. From the correlation results, it is found that the coal slope is towards the southwest - northeast by experiencing thickening and thinning layers.

Abstract

Edible film is a thin layer that has the function of packaging or coating food that can be consumed directly with the packaged product. Edible film made from starch has the disadvantage that it is fragile and easy to use. The aim of this research is to determine the effect of glycerol concentration on the characteristics of edible film from kimpul tuber starch. The experiment was carried out using a completely randomized design (CRD), with 4 treatments with glycerol concentrations of 0.5%, 1.0%, 1.5% and 2.0%, each treatment was repeated 4 times. The results showed that the solubility, thickness, wvtr, and elongation values increased with increasing glycerol concentration used. A glycerol concentration of 2.0% produces the highest solubility value of 58.33%, thickness of 0.174mm, wvtr 33.38g/m2.hour, and elongation is found at a glycerol concentration of 1.0% with a value of 21.397%. However, on the contrary, the transparency, compressive strength, and tensile strength of edible film decrease with increasing glycerol concentration. Glycerol concentration has a significant effect on the values of solubility, thickness, transparency, compressive strength, tensile strength and elongation, but does not have a significant effect on the value of the water vapor transmission rate (WVTR). A glycerol concentration of 1% produces the best edible film with a solubility value of 38.33%, thickness of 0.125mm, transparency of 18.656%/mm, WVTR of 28.25g/m2.hour, compressive strength of 103.56N/m2, Tensile Strength of 2.9428MPa, and Elongation 21.397%.

Abstract

Palm oil shells are one of the solid waste in palm oil processing plants, currently the use of palm oil shells is only used as activated charcoal. Though the mineral content potential contained in palm oil shell is very large, one of them is silica (SiO2) of 71.1% with a large amount of this can be used as a source of silica. The source of silica shell of palm oil in this research is used as the basic material of zeolite manufacture. Zeolite is a hydrated aluminasilicate compound which has many benefits such as catalyst, adsorbent, and ion exchanger. Zeolite fabrication method is a common and widely used hydrothermal method, because this process does not require a high temperature with a relatively short time. Palm oil shells are used to remove carbon in them and the ash is characterised using XRF. Palm oil ash was crushed together with NaOH they were melted at 500°C or 1 hour, and added with distilled water and soaked 24 hours, produced Sodium Silicate and characterised using FTIR. For Alumina, NaOH was reacted with Al(OH)3 to produce Sodium Aluminate and characterised using FTIR. Zeolite preparation was carried out by mixing the sodium silicate and sodium aluminate reactants and the zeolite crystallisation process was carried out using a hydrothermal reactor heated in an oven by varying the hydroternal temperature at 120˚C, 150˚C and 180˚C for 8 hours. Synthesized zeolite was characterised using XRF, XRD and SEM. FTIR analysis Sodium Silicate has been formed at wave number 981.19 cm-1 symmetric vibration Si-O (Na) strectching, and Sodium Aluminate has been formed at wave number 719.87 cm-1 with symmetric vibration Al-O (Na) stretching. The result of XRD characterisation at 120°C produces mixed zeolite of type 4A, Sodalit and Faujasit. At the temperatures of 150°C and 180°C formed Sodalite type zeolite. The best crystallinity was obtained at a hydrothermal temperature of 150°C and analysed using SEM, showing the small cubic crystal form bonding to each other to form an elongated geometry.

Abstract

Edible films from native starch have some weaknesses, one of which is the water vapor transmission rate is still high. To lower the rate of water vapor transmission may be used starch composites starch. This study aimed to obtain ethanol volumes that can produce modified starch with the smallest size, produce composite starch for edible film and to determine the characteristics of edible film made out of natural starch and edible film from composite starch (natural starch and modified starch). This research was conducted in 3 stages, namely: extraction of yam starch, modification of yam starch by precipitation method and production of edible films from natural starch and composite starch. This study was designed to produce modified starch using 5 levels of ratio between starch paste volume and ethanol volume 1:5, 1:7.5, 1:10, 1:12.5, 1:15. The results showed that the treatment of ratio 1:15 (1500 ml ethanol) produced the smallest particle size of starch 3,417 x 5,945 µm up to 15,038 x 16,708 µm with starch yield of 80%. Edible films made from composite starch have different characteristics than natural starch. Edible film from composite starch produces higher thickness values of 0.156 ± 0.006 mm, lower solubility of 27.385 ± 3.808%, lower transparency of 10.657 ± 0.278% /mm and lower water vapor transmission rate (WVTR) of 18.423 g / m2 hour, and compressive strength of 841.8 ± 6,823 gF than natural starch edible film.

Abstract

The common form of palm sugar is usually in solid form and needs to be dissolved before use. To facilitate utilization, palm sugar is processed into liquid palm sugar. One of the issues encountered during the production of liquid palm sugar is the formation of foam, which can decrease the quality of the liquid palm sugar. Therefore, measures are needed to anticipate foam formation, including the addition of candlenut seeds and coconut oil. This study aims to determine the influence of the addition of candlenut seeds and coconut oil on the physical and chemical characteristics of liquid palm sugar, identify the optimal levels of candlenut seeds and coconut oil that meet the national standard (SNI) for liquid palm sugar, and produce a liquid palm sugar product preferred by consumers. The research employed a Randomized Complete Block Design (RCBD) with a single factor and six treatment levels of candlenut seeds and coconut oil (0%, 0.1%, 0.3%, 0.5%, 0.7%, and 0.9%). Data analysis was conducted using Analysis of Variance (ANOVA). Based on the research results, the addition of candlenut seeds and coconut oil significantly influenced the viscosity of liquid palm sugar but had no significant effect on its color and moisture content. The addition of candlenut seeds and coconut oil had a significant impact on the chemical quality of liquid palm sugar, affecting ash content and total insoluble solids but showing no significant effect on pH and total dissolved solids. The treatment with 0%, 0.1%, and 0.3% additions of candlenut seeds and coconut oil met the quality requirements for moisture content, while the ash content in the 0%, 0.1%, and 0.3% treatments also complied with the standards. The addition of 0.9% candlenut seeds and coconut oil resulted in liquid palm sugar that met both SNI standards and consumer preferences.

Abstract

Due to the increasing reduction in non-renewable natural resources such as petroleum and the increasing amount of ash and charcoal waste from palm oil mills that has not been utilized, the author synthesizes the silica content from a mixture of ash and charcoal from palm oil waste to be used as a Cr/SiO2 catalyst which will be used for cracking. catalytic from CPO (Crude Palm Oil) to gasoline.  This research aims to determine whether a mixture of waste ash and charcoal from the PTP VI Sungai Bahar factory waste can be used as a silica source to produce Cr/SiO2 catalysts and to determine its activity in the catalytic cracking of CPO into gasoline.  The cracking process was carried out in a fixed bed reactor which consists of a horizontal reactor and a vertical reactor and equipped with an electric heater and temperature controller. Catalytic cracking was carried out with several ratios of catalyst : CPO, namely 1:20, 1:25, and 1:30.  Similar cracking process without catalyst (the thermal cracking) was also carried out as a comparison.  The conversion of CHP into gasoline using ratios 1:20, 1:25, 1:30 were 13.67%, 10.78%, 11.59% respectively. Meanwhile, the gasoline conversion produced by thermal cracking was only 9.46%, 9.95%, 6.86%. These results show that catalytic cracking produced more gasoline than thermal  cracking.
