Abstract

Waste is an environmental problem caused by the activities of living things. The synthetic waste group or what is often found in the form of plastic and the like is a group of waste that is very difficult to degrade. This can be overcome by using lipolytic bacteria. This research aims to analyze lipolytic bacteria which can be used to biodegrade plastic waste in the Bonoloyo TPU, Makam Haji TPS, and the Bengawan Solo river flow. This research uses quantitative descriptive methods. Screening for lipolytic bacteria degrading polystyrene (PS) showed that the highest population of lipolytic bacteria isolated from public burial places of 15.6 x 104. Meanwhile, lipolytic screening with the highest average clear zone formed was 0.641 cm which came from TPS 1, then average -The highest average lipolytic index came from SBS 2 with a figure of 1.6525 cm, the largest average colony diameter came from TPS 1 soil samples at 0.45 cm. The degradative nature of bacteria on plastic above shows that the Bengawan Solo river has microbes with the highest ability compared to microbes from TPS and TPU, namely 22.42%. The degradation between TPU, SBS, and TPS is significantly the same. PS degradation in Bonoloyo TPU shows significant physical changes.

Abstract

A cemetery is a burial place managed by the government. Inside the TPU, the body is decomposed by microorganisms, one of which is lipolytic bacteria, because the human body is composed of about 12.5–13.60% lipids. Research on lipolytic bacteria from TPU in Indonesia has not been found, even though it has the potential to obtain lipolytic bodies. Therefore, this research was conducted to select lipolytic bacteria from TPU and provide simple assistance. A total of 45 bacterial isolates from TPU Bonoloyo Surakarta were selected for their lipolytic activity using tributyrin agar media. Lipolytic activity was determined using the lipolytic index (LI). Bacterial isolates with lipolytic potential were identified based on colony morphology and Gram staining. The results showed that 30 isolates (67%) showed lipolytic activity, with the highest LI value of 5.43 (BLB 9) after 2x24 hours of incubation. Bacterial isolates that have lipolytic activity are white colonies with circular shapes. The results of Gram staining showed that the bacterial isolates belonged to a group of Gram-negative bacteria in the form of cocci. The conclusion put forward is that public cemeteries (TPU) have the potential to store isolates of lipolytic bacteria dominated by Gram-positive bacteria by as much as 57%

Abstract

Four endophytic bacteria have been isolated from banana kluthuk plants and banana ambon. Previous study showed that they produce Indole Acetic Acid (IAA). This study aimed to analyze the effect of endophytic bacterial inoculation on plant height and the number of rice root. For this reason, two endophytic bacteria of each klutuk banana and ambon banana plants were cultured and examined for growth rate using a 600 nm spectrophotometer. Isolate growth was calculated every two hours for 16 hours of bacterial growth in NB media. Bacterial inoculation experiments on rice plants were carried out with five replications. This inoculation begun with germination of rice seeds until the radicle was observed. Then germinated rice seedlings were soaked in a bacterial suspension for 1 hour at room temperature. The results showed the exponential phase of all isolates was observed at 6 hours with shaking. Inoculation using A22 and A51 isolates significantly increases plant height, number of leaves. While, A22 isolate significantly increased the number of roots compared to the uninoculated plants (control). It supports the potential of endophytic bacteria from banana kluthuk and ambon plants.

Abstract

AbstractFive isolates of endophytic bacteria from the roots of klutuk and ambon banana plants produce indole acetic acid (IAA) hormone. However, the evidence of its potential as Plant Growth Promoting Bacteria (PGPB) has not been observed. Therefore, this study aims to determine the effect of bacterial isolate to increase the growth of rice and maize plants. The growth rates of bacterial isolates were measured before the inoculation into the plant root. The root inoculation was performed following a complete randomized design. Root inoculation was carried out using 5 isolates of endophytic bacteria in rice and maize plant seedlings, and the process was repeated 15 times (n=15). The growth of rice and maize plants was monitored from 1st day after planting (dap) to the 14th dap. The collected data were analyzed by student t-test with a significant level of 5% (a= 0.05). The results showed that the logarithmic phase of all isolates was reached at 4 to 16 hours and K10, K25, K35, K111, and A41 isolates increased the height of plants while the K111 isolate can significantly increase the plant height compared to the control. This experiment revealed that the endophytic bacteria from banana plants increase the rice and maize plant’s growth.AbstrakLima isolat bakteri menghasilkan hormon indole acetic acid (IAA) yang berpotensi memacu pertumbuhan tanaman.

Abstract

SuleMu is a soy milk product produced by KL LazisMu SMP Muhammadiyah 7 (SMP MUTU) Colomadu, Karanganyar Regency, Central Java Province. Although SuleMu packaging has a label, it lacks nutritional information. Additionally, its marketing strategy is still traditional. Therefore, this community service aims to add nutritional information to SuleMu packaging and create a digital marketing platform. The implementation of this program began with coordination, nutritional analysis, packaging label redesign, digital marketing training, the creation of a SuleMu digital marketing platform, and evaluation. The results of the nutritional analysis of SuleMU per 100g were: protein (3.4g), fat (3.3g), sugar (5.1g), crude fiber (2.6g), and calcium (40mg). This data has been added to the new SuleMu label. For digital marketing training, the average pre-test scores for WhatsApp Business and Instagram materials were 72.57 and 73.14, respectively, while the average post-test scores were 87.43 and 81.43. SuleMu also now has digital marketing accounts on Instagram and WhatsApp Business.

Abstract

Polyethylene (PE) plastic is one of the most widely used for multiple purposes and leading the environmental problems. Lipolytic bacteria are promising agents to reduce the plastic waste. The dry weight of PE plastic was reduced by 33 % in the Winogradsky's column after 45 days of incubation. However, the lipolytic bacteria responsible for those reduction was unknown. This study aimed to characterize and identify the potential lipolytic bacterial isolates forming biofilm on polyethylene PE plastics. Samples of lipolytic bacterial isolates were screened on tributyrin selective media based on the formed clear zone. Moreover, the 16S rRNA genes of the two most potential lipolytic bacterial isolates were amplified. Then, the amplicons of the 16S rRNA gene were sequenced. This study found two potential lipolytic bacteria isolates, AB A-2 and AB M-3, which had the characteristics of round colonies, wavy edges, convex surfaces, and milky white color. The two isolates are gram-positive and have the shape of Coccobacillus cells. The molecular identification showed that AB A-2 isolate was Bacillus sp., while AB M-3 isolate was Bacillus amyloliquefaciens. This finding contributes to novel bacterial isolates that potentially overcoming the plastic waste problem.

Abstract

Indonesia faces dual environmental challenges from plastic pollution and agricultural waste accumulation. To address these issues, innovative solutions are needed to transform waste into sustainable materials. This study valorizes rice straw (Oryza sativa L.) cellulose and used cooking oil (UCO) glycerol to develop biodegradable plastics through an accessible method. Cellulose was extracted from rice straw via alkaline (10% NaOH) and bleaching (20% H₂O₂) treatments, while glycerol was recovered from UCO through saponification. Bioplastic films were synthesized by solution casting with varying glycerol volumes (6, 9, 12 mL) and cellulose particle sizes (fine, semi-fine, coarse). Results demonstrated exceptional biodegradability, with ≥ 80% weight loss within 14 days in EM4-supplemented soil burial tests outperforming commercial cassava-based bioplastics (25% degradation). Higher glycerol volumes (12 mL) combined with coarse cellulose maximized water solubility (69.39%) and absorption (14.29%), while lower glycerol (6 mL) with fine cellulose minimized water uptake (5.88%). All formulations exceeded thickness standards (0.438–0.554 mm vs. JIS ≤ 0.25 mm), enhancing rigidity but reducing flexibility. Organoleptic analysis confirmed glycerol content inversely affected transparency and texture smoothness.

Abstract

Original "SuleMu" soy milk currently has limited shelf life without refrigeration. Therefore, it is crucial to assist partners in enhancing product competitiveness and diversification. The primary objectives of this community engagement activity were to improve SuleMu's marketability through the addition of new flavors and the provision of nutritional value analysis, as well as to enhance product quality by developing derivative products such as soyghurt and frozen yogurt. The activity stages included: (1) mentoring for the diversification of SuleMu derivative products, (2) nutritional value analysis of derivative products, (3) designing product labels compliant with standards, and (4) conducting a market survey on consumer preferences for SuleMu derivative products. Results indicate that SuleMu is now available in new flavors: melon, chocolate, and strawberry. The nutritional content per 100 grams is 3.4–3.5 grams of soluble protein, 3.3–3.7 grams of fat, 5–5.7 grams of reducing sugars, 2.6–3.6 grams of crude fiber, and approximately 39–40 mg of calcium. SuleMu production increased from 5 kg of soybeans to 6 kg per day. Furthermore, consumers showed high interest in the "Soyoghurt" frozen yogurt derivative product, with 42.4% being very interested and positive evaluations regarding taste (36.1%) and affordable price (29.2%). Overall, this community engagement activity successfully increased SuleMu's production by 17%, and soyghurt demonstrates significant potential for development as a highly competitive new innovation.
