The increasing demand for paper has led to a shortage of wood-based raw materials, thus requiring environmentally friendly alternatives. This study aims to analyze the physical, mechanical, and morphological characteristics of paper made from cassava peels (Manihot esculenta Crantz) and oil palm fruit fibers (Elaeis guineensis Jacq.) as eco-friendly paper raw materials. The research method involved pulp preparation through delignification using 3.5% HNO₃ and 3% NaOH, bleaching with 10% H₂O₂, paper sheet formation with varying compositions (A = 70:30, B = 50:50, C = 30:70, D = 10:90), followed by grammage testing and tensile strain testing. The results showed that the grammage values ranged between 96.3–99.7 g/m², while tensile strain ranged between 2.6–4.4%. The study concluded that the best composition was found in sample C (30% cassava peel : 70% palm fiber) with a grammage of 98.5 g/m² and tensile strain of 3.2%. The implication of this study is that cassava peel and palm fiber waste have the potential to serve as alternative paper raw materials that meet the quality standards of A-grade printing paper (SNI 7274:2008), while also supporting the reduction of dependence on wood.

This study aims to analyze the effect of using cassava (Manihot esculenta crantz) as a carbohydrate-based feed ingredient on body weight gain in beef cattle. The review was conducted using a descriptive literature study approach based on sixteen scientific articles discussing the nutritional composition, processing methods, and performance responses of beef cattle fed cassava-based diets. The analysis shows that cassava contains 17.45–88.6% dry matter, 2.4–21.45% crude protein, and 11.35–92.2% nitrogen-free extract, with variations influenced by plant part, processing method, and hydrocyanic acid (HCN) content. Processing techniques such as fermentation and ensiling can reduce HCN levels by more than 70% while increasing crude protein content up to 25%, thereby improving digestibility and feed efficiency. The inclusion of cassava in the form of flour, dried chips, pulp, or fermented peel consistently enhances dry matter intake and average daily gain (ADG) of beef cattle at inclusion levels of 20–50% in the diet. Overall, cassava has strong potential as a locally available, economical, and sustainable feed ingredient to improve beef cattle productivity.

Anemia in pregnancy remains a common public health problem and may lead to adverse outcomes for both the mother and the fetus, highlighting the need for effective and practical interventions. This study aimed to analyze the effect of cassava leaf (Manihot esculenta) consumption on hemoglobin levels among second-trimester pregnant women at UPT Puskesmas Rum Balibunga. A quasi-experimental study with a pretest–posttest design without a control group was conducted. The sample consisted of 30 second-trimester pregnant women with mild anemia, selected using purposive sampling. The intervention involved daily consumption of cassava leaves for 14 consecutive days. Hemoglobin levels were measured before and after the intervention using standardized examination tools. The results demonstrated a significant increase in hemoglobin levels following cassava leaf consumption, with a mean increase of 1.2 g/dL. These findings suggest that cassava leaves, which are rich in iron, vitamin C, and protein, can enhance hemoglobin synthesis and serve as a local food-based nutritional intervention. Therefore, cassava leaf consumption can be recommended as an alternative or complementary strategy for preventing and managing anemia among second-trimester pregnant women in primary healthcare settings. 

Cassava (Manihot esculenta) is a staple food that is widely consumed by the Indonesian population, especially in rural areas. However, during post-harvest handling and storage, cassava is highly susceptible to contamination by microorganisms, particularly fungi. These fungi can cause damage to the food, reduce its nutritional quality, and even produce mycotoxins that are harmful to human health. The increased risk of contamination has become an important concern in efforts to improve the quality and safety of cassava food products. This study aimed to identify the morphology of fungal colonies and the characteristics of fungal cell walls isolated from cassava stored in open environmental conditions for several days. The methods used in this study included isolation using Potato Dextrose Agar (PDA) media, macroscopic observation of fungal colony morphology, including color, edge, elevation, and texture, as well as Gram staining to observe the fungal cell wall properties. The results of this study revealed a diversity of fungal colony morphology, with three dominant types suspected to belong to the genera Aspergillus, Penicillium, and Rhizopus. Gram staining showed that the three isolates were characterized as Gram-negative, indicated by the absorption of safranin as the secondary stain. This study provides an initial overview of the types of fungi that may develop on cassava during storage, and it offers a foundation for further studies on the toxicity and food microbiology applications related to cassava. Morphological identification and Gram staining play an essential role in the initial screening before molecular identification is performed.

This study aims to explore the potential of cassava extract (Manihot esculenta)-based growth media for isolating microorganisms from soil. The use of alternative culture media is crucial, especially in regions with limited access to commercial media such as Nutrient Agar or Potato Dextrose Agar, which are relatively expensive. Cassava, a tropical tuber rich in starch and widely available in Indonesia, offers significant promise as a natural substrate for microbial growth. Microbial isolation was performed using a serial dilution method on soil samples collected from an organic garden. The media was prepared from cassava juice mixed with agar and glucose, sterilized, and poured into petri dishes. After inoculation, microbes were incubated for seven days at room temperature. Colony morphology was observed macroscopically, and Gram staining was used to identify bacterial characteristics. The results revealed that cassava extract media effectively supported the growth of diverse microbial colonies, varying in shape, color, and edge structure. Most isolates were identified as Gram-positive, with rod and coccus forms. The presence of pigmented colonies indicates the potential of certain isolates to produce bioactive compounds. In conclusion, cassava extract-based media is a viable alternative for soil microbiology studies. It is not only cost-effective but also facilitates the exploration of local microbial diversity with potential applications in biotechnology, including bioremediation and enzyme production. This approach encourages the use of indigenous resources in scientific research, promoting sustainability and accessibility in microbiological practices.

Cassava tapai is a traditional Indonesian food product produced through the fermentation of cassava (Manihot esculenta) with the help of microorganisms, particularly the yeast Saccharomyces cerevisiae. This product not only has cultural and economic value but also contains bioactive compounds with health benefits, such as probiotics and fermentation metabolites. However, the quality of cassava tapai is significantly influenced by process factors, particularly incubation time. This study aimed to analyze microbial growth and changes in the chemical properties of cassava tapai with varying fermentation times. The study was conducted using an experimental design with fermentation times of 24, 48, and 72 hours at room temperature. The main parameters observed included the number of microbial colonies (cfu/g), pH changes, and alcohol content produced during the fermentation process. The results showed that microbial growth increased significantly, peaking at 48 hours, with the highest colony count compared to other treatments. After 72 hours, the number of colonies decreased, likely due to ethanol accumulation and decreased substrate availability, which reduced microbial activity. The pH value tended to decrease with increasing fermentation time, reflecting the formation of organic acids during the process. Meanwhile, the alcohol content showed an increasing trend from the beginning to the end of fermentation, although the growth rate was relatively slower at 72 hours. These findings confirm that varying incubation length significantly influences microbial dynamics and chemical changes in cassava tapai. The optimal fermentation time is around 48 hours, as this is the phase where the balance between microbial growth, alcohol formation, and sensory characteristics is maintained. The results of this study can serve as a basis for developing standards for cassava tapai production at both household and industrial scales, while also strengthening efforts to preserve traditional foods with a modern scientific approach.

Solid waste from the tapioca processing industry, which is based on cassava (Manihot esculenta), is a medium rich in organic matter, particularly starch, that supports the growth of various types of microorganisms, especially fungi and bacteria. This study aims to isolate and observe the morphology of microorganisms from solid waste of cassava from the tapioca industry using Potato Dextrose Agar (PDA) medium in a series of pharmaceutical microbiology practicum. Waste samples were taken from the tapioca processing site, then underwent a serial dilution process and inoculation into PDA medium, which was incubated at 28–30°C for 5 days. The isolation results showed the growth of microorganisms with diverse colony morphologies, which are suspected to originate from the genera Aspergillus, Penicillium, and Rhizopus, based on macroscopic and microscopic characteristics. The presence of these microorganisms indicates the potential utilization of cassava waste as a source of microbial isolates for biotechnological and pharmaceutical applications, such as enzyme production and development of bioactive compounds. This practicum activity also contributes to increasing students' understanding of isolation techniques, microorganism characterization, and their role in biological-based waste management.

Cassava (Manihot esculenta) is a staple food rich in carbohydrates and widely consumed by people in various regions, especially in tropical regions such as Indonesia. Besides being easy to cultivate, cassava also has a high economic value. However, cassava has a major weakness, namely its perishability after harvest. This damage is often caused by contamination by microorganisms, especially fungi, which can grow rapidly in unhygienic and humid storage conditions. Fungal contamination not only causes odor and reduces sound quality but also has the potential to produce mycotoxins that are harmful to human health. Therefore, identifying the type of fungus growing on cassava is very important. The purpose of this study was to determine the presence and type of fungus growing on cassava through a colony morphology approach and Gram staining using crystal violet. The research method began with dilution of cassava samples, then inoculated into Nutrient Agar (NA) media, incubated for 48 hours at room temperature, and continued with microscopic examination. Staining with crystal violet aims to clarify the morphological structure of the fungus such as hyphae and spores. Observations revealed the growth of characteristic fungal colonies, as well as hyphal and spore structures that readily absorbed crystal violet. This demonstrates that this simple morphological and staining method is quite effective in providing initial insights into fungal identification. This information is expected to form the basis for developing safer and more durable cassava storage methods. Further research is recommended on specific identification using molecular testing. This step will broaden our understanding of the toxicological potential and post-harvest handling of cassava.

Cassava tape is a traditional fermented product widely consumed in Indonesia, especially in rural areas. It is produced from cassava (Manihot esculenta) through the activity of microorganisms during the fermentation process. The presence of microbes in this process plays a crucial role in the flavor, aroma, texture, and final quality of the product. The microorganisms involved, including bacteria, molds, and yeasts, work synergistically to break down the carbohydrate components of cassava into simpler products, resulting in the sweet taste and distinctive aroma of tape. This study aimed to identify and characterize the microbes present in cassava tape through isolation and microscopic staining using safranin. The isolation process involved several stages: sequential sample dilution, inoculation onto Nutrient Agar (NA) media using the pour method, and incubation at 37°C for 24 hours. The growing microbial colonies were observed macroscopically, then collected and subjected to simple safranin staining to determine the shape and distribution pattern of the microbial cells microscopically. Observations revealed colonies with diverse morphologies, including rod-shaped (bacilli) and spherical (cocci), evenly distributed across the observation area. This indicates that cassava tape contains microorganisms of various morphologies that play a role in the fermentation process. Simple safranin staining has been shown to provide an initial overview of the presence and form of microbes, although further identification to the genus or species level requires further tests such as Gram staining, biochemical tests, and molecular analysis. These findings open up opportunities for further in-depth research into consumption safety, the functional role of microbes in tape fermentation, and its potential use as a source of natural probiotics in traditional fermented foods.  

This study aims to identify the microscopic structure of fungi growing in Manihot esculenta (cassava) waste using Gram A (crystal violet) staining. Cassava waste is a type of organic waste that has the potential to serve as a growth medium for various microorganisms, including fungi. Microscopic observations were conducted to determine the morphology of fungal cells that grow naturally in the waste. The Gram staining method was used to facilitate visualization of the fungal cell wall structure, with an emphasis on crystal violet staining as the primary dye. Waste samples were fermented for 3–5 days to allow fungal growth, then taken and microscopic slides were made. The results showed the presence of purplish-purple fungal hyphae and spores, indicating that the fungal cells were able to retain the crystal violet stain. This structure indicates that the type of fungus growing has a thick cell wall and is likely included in the Ascomycota or Zygomycota group. This identification demonstrates the potential use of Manihot esculenta waste as a substrate for microbiological studies and the development of fungal-based biotechnology. This study also emphasizes the importance of simple staining techniques in assisting the initial identification of microorganisms in organic media.

This study aimed to evaluate the effect of substituting cassava leaves (Manihot esculenta Crantz) into a complete feed based on odot grass (Pennisetum purpureum cv. Mott) on in vitro rumen fermentation characteristics, including gas production, dry matter degradation (DMD), organic matter degradation (OMD), ammonia (NH₃) concentration, and microbial protein synthesis. A laboratory experiment was conducted using a Completely Randomized Design (CRD) consisting of five dietary treatments (0%, 5%, 10%, 15%, and 20% cassava leaf inclusion) with four replications each. The feed samples were incubated for 48 hours using rumen fluid collected from slaughtered Limousin cattle, selected purposively from the Ruminant Abattoir in Malang City based on consistent diet and health status to minimize variability. Feed ingredients were sun-dried, ground, and mixed into complete feed formulations using standardized proportions. In vitro gas production was measured using a gas-tight syringe technique, while DMD and OMD were calculated by weighing residues after fermentation. NH₃ concentrations were analyzed using the Conway microdiffusion method, and microbial protein synthesis was estimated based on the weight of microbial biomass derived from fermentation residues. All variables were statistically analyzed using ANOVA followed by Duncan’s Multiple Range Test at a 5% significance level. The results showed that a 20% substitution of cassava leaves significantly (P<0.01) improved the gas production rate, DMD, OMD, NH₃ concentration, and microbial protein synthesis, while decreasing gas production potential. These findings demonstrate the potential of cassava leaves as a sustainable protein-rich ingredient in ruminant complete feed formulations.
