Abstract

Porang (Amorphophallus oncophyllus) is a tuber plant originating from Indonesia. This plant is less well known compared to other tuber plants. Porang has various important uses, especially in the food and industrial sectors. Indonesia ranks 5thas the largest supplier of porang in the world. Drying porang is an important stage in the post-harvest processing of porang plants. The drying process must be done carefully so as not to damage the quality of the porang. The right drying method, appropriate drying temperature, and humidity control must be considered to achieve optimaldrying results. A tray dryer is a drying device that contains shelves to store the material being dried. Drying with this tool uses hot air gusts that are passed over the material being dried. The aim of this research is to determine the effect of drying temperature variations on the moisture content and drying rate of porang using a laboratory-scale tray dryer. Drying is carried out on stick-shaped porang with a thickness of 1 cm and a total weight of 125 grams. The temperature variations in this drying are 50OC, 60OC, and 70OC, with a drying air speed 1 m/s. The research results show that the higher the drying air temperature in the tray dryer, the lower the moisture content in the porang and the faster the drying rate. When the drying air speed and porang thickness are constant, the optimal porang drying temperature is 70OC

Abstract

Cowpeas are a particular kind of legume and containthe second highest protein after soybeans. Cowpea is inadequate because it has antinutritions such as tannins, phytic acid, and trypsin inhibitors. Pretreatment is necessary to lower anti-nutritional elements and increase the nutrition of cowpeas' ability to be digested. This study was done to determine the effect of various pretreatment techniques on enhancing cowpea flour's nutritional qualities and antioxidant potential. A completely randomized design with one factorial and three analytical replications was done. The findings of this study demonstrate that cowpea flour may be made using a variety of pretreatments, including germination, roasting, or its combination. A combination of germination treatment followed by roasting at 1400C for 40 minutes can significantly reduce the phytic acid, tannin, and color content and increase the yield and density of the cowpea flour produced. In addition, the initial treatment with the combination had the highest protein content of 46.88%, the highest total phenol, and the most increasedRadical Scavenging Activity(RSA) or antioxidant activity of 47.00%. The most effective method to produce cowpea flour withthe best nutritional properties and antioxidant potential is a combination of germination and roasting processes as a pretreatment

Abstract

A job description is a division of work tasks for employees that aims to ensure that employees have responsibility for their respective jobs, which have been divided by their superiors. This research aims to encourage companies to consider the placement of human resources in their respective jobs. The method used is a survey and direct interviews with business owners using an open questionnaire to obtain data on the business. The data sources used are business owners, places or events, and employees at the Pisang Segading Ponorogo MSME business. Based on the research results, it can be concluded that the UMKM Pisang Segading Ponorogo has not implemented job descriptions properly for three employees, so employees still often work concurrently with eight working hours so that the impact of the product produced does not meet the production target of 25 kg, apart from that in the UMKM Pisang Segading Ponorogo also does not yet have an organizational structure so that employee placements are still not well structured. Efforts made to address these obstacles are by adding employees by threatening employees and employees at the Pisang Segading Ponorogo UMKM by providing job descriptions so that they will be more focused and productive in their respective jobs. So, the solution above can support the progress and curiosity of UMKM Pisang Segading Ponorogo.

Abstract

High-quality air is essential for human survival. The present-day has a negative effect on air quality. Air contamination from the harmful compound H2S is an important problem. The primary source of H2S discharges is the oil and gas industry, where it is a by-product of resource harvesting and processing. Further sources of H2S discharges into the atmosphere include mining, waste management, and fossil fuel burning. H2S generates a malodorous scent resembling that of decayed eggs, which can prompt respiratory discomfort and irritation in humans and animals. At elevated concentrations, it may induce toxicity and even fatalities. Biofiltration is one of the latest remarkable technological advances for mitigating this issue. This method employs microorganisms to convert H2S into less harmful compounds. Biofiltration offers the major benefit of low operational expenditure and minimal environmental impact. This paper contributes to our comprehension of the microbial parameters, designs, models, applications and processes that affect biofilter efficiency. Diffusion-based biofiltration models show greater efficacy in design systems. Furthermore, advances in media, including the use of hollow cylindrical particles, have increased the efficiency of biofiltration. Sulfur-oxidizing microorganisms, such as Thiobacillus sp., play a pivotal role in decreasing H2S compounds. It is crucial to regularly monitor and regulate moisture levels, pH, temperature, and nutrient content to secure optimal and consistent biofiltration performance. The technology's effectiveness and stability heavily depend on precise control of these parameters. Biofiltration technology is hailed as a promising approach to manage H2S compounds, safeguard air quality, and preserve human health and the environment.

Abstract

Bamboo plants in Indonesia are familiar plants and have not been utilized optimally. Most people only use the stems for daily needs and a small part for industry, while the leaves are left as waste. Bamboo leaves have a fairly high silica content. Bamboo leaves that have fallen and are scattered on the ground (bamboo leaf litter) are a potential source of natural silica. Silica fertilizer in agriculture is still very necessary, especially in nanosized. Through silica extraction from bamboo leaf litter, it is hoped that it will be able to meet agricultural silica needs and reduce bamboo leaf waste. The aim of this research is to modify the synthesis of silica from ori bamboo leaf litter (Bambusa blumeana) by extracting NaOH and KOH using the hydrothermal sol-gel method to produce nano silica. Nano silica production uses the hydrothermal method because it does not require large costs, is more effective, and has a high level of purity. Synthesis of original bamboo leaf litter silica using the hydrothermal sol-gel method. Bamboo leaf litter ash was analyzed using the XRF test, and silica was analyzed using the SEM-EDX mapping test to determine its morphology and content. The research results showed that synthesis with sodium produced higher levels of bamboo leaf silica compared to potassium. The size of the silica particles obtained is still in the form of micrometers (47–52 µm). Bamboo plants in Indonesia are familiar plants and have not been utilized optimally.

Abstract

The abundance of bagasse waste from sugar cane processing needs special attention apart from being used for direct combustion in boilers. Sugarcane bagasse waste can be further processed by pyrolysis so that it will produce bio-oil, bio-gas and char products which have the potential to be used as fuel or high-value chemicals. Pyrolysis of bagasse was carried out to study the effect of temperature and the ratio of the amount of Ni catalyst on the yield and composition of bio-oil in the form of oxygen to carbon (O/C) ratio, hydrogen to carbon (H/C) ratio, higher heating value (HHV), content of oxygenated compounds and range of aromatic compounds. Pyrolysis of bagasse is carried out in a fixed bed reactor with a heating rate of 10-12 ºC/minute to the desired temperature. Pyrolysis with and without a catalyst was carried out at a temperature range of 300-600 ºC with a variation of Ni catalyst weighing 2.5 grams and 5 grams. Liquid product analysis was tested using GCMS (Gas Chromatography and Mass Spectroscopy) to determine the compound content in the liquid product resulting from pyrolysis of sugarcane bagasse. Bio-oil resulting from pyrolysis of sugarcane bagasse contains several dominant compounds including alcohol, fatty acids, esters, carotenoids and levoglucosan. However, the yield of sugarcane bagasse bio-oil without catalyst was dominated by high levoglucosan, namely 70.52%. Meanwhile, the bio oil resulting from pyrolysis which varied with 2.5 grams and 5 grams of Ni catalyst was dominated by esters, namely 69.07% and 81.68% respectively. These compounds have different chemical properties and applications, and understanding the composition of bio-oil can help in deciding how to use it efficiently.

Abstract

This research aims to compare the characteristics of briquettes as an energy source produced from coffee shell waste and cocoa waste. The briquette-making process involves carbonization to produce charcoal as the primary raw material for briquettes. Carbonization time varies, influenced by the type of waste and size of the material. After that, the charcoal is reduced and sifted into fine and coarse powder. Briquette molding uses pressure using a pipe as a mold. The characteristics of briquettes are analyzed through water content, density, burning rate, and ash content. The research results show differences in characteristics between coffee and cocoa waste. The carbonization process affects the time and mass difference of raw materials. Cocoa pod shells require the longest (±35 minutes), while cocoa bean shells require the shortest (±17 minutes). Next, making briquettes involves molding and pressing using a pipe as a mold. The results showed that waste cocoa pod shells and cocoa bean shells produced more briquettes than waste coffee pod shells and coffee bean shells. The moisture content of briquettes from all types of waste meets the standards, but the density of the raw material for coffee husk waste is low, while the briquettes have a high density. The burning rate of briquettes varies, with cocoa bean shell briquettes having the fastest burning rate and producing much smoke. The ash content of cocoa pod husk briquettes exceeds the standard, while cocoa bean husk briquettes have low ash content. The density of the raw material is correlated with the moisture content of the briquettes. The highest burning rate occurs in cocoa bean shell briquettes, influenced by low density and high water content. The ash content of the briquettes meets standards, except for cocoa shell briquettes. This research proves that cocoa and coffee shell waste can be processed into briquettes with different characteristics.
