Authors:   Kenyatta University, Mucheru P , Chege P , Muchiri M
Published: December 2024

With the increasing demand of health promoting food products, formulations of yoghurts are changing more towards live probiotic starter culture milk fermentation and fortification with plant-based food ingredients to improve the flavour and nutrition composition. Synbiotic yoghurts fermented with probiotic microbes and fortified with prebiotic food ingredients have become very popular as functional foods due to their scientifically proven bioactive compounds that promote human gut health and alleviate dysbiosis. The aim of the current study therefore, was to assess the physiochemical, nutritional proximate composition and viability of probiotics in formulated yoghurt fortified with a novel purple-leaf tea (Camelias sinensis) puree that is rich in anthocyanins, bioactive polyphenols. Whole milk was fermented with probiotic starter culture (Lactobacillus acidophilus (LA-5), Bifidobacterium animalis subsp. lactis -ABT 5) from CH Hansens Limited. Subsequently, the yoghurt was fortified with a novel purple tea puree at the Food and Tea Science Workshop of Karatina University, Kenya. Proximate composition and physiochemical properties (pH and mineral salts profile) were analyzed both in the formulated probiotic yoghurt (PYFPT) and control yoghurt without the tea puree. The viability of the probiotic colony forming microbes was determined using the De Man, Rogosa and Sharpe (MRS) anaerobic bacteria selective culturing agar media. The pH results of PYFPT (4.24 ± 0.04) was not significantly different (p< 0.05) to that of the control yoghurt even after 28 days of refrigerated storage. However, proximate composition recorded significant differences except for the crude fiber content (0.01 ± 0.01 %). A higher percent moisture content and crude lipid was recorded in the control yoghurt (88.18±0.01 and (2.11 ± 0.02) than the PYFPT (78.14±0.04 and 1.33 ± 0.09). Inversely, higher percentage of crude protein, carbohydrates and crude mineral salts were recorded in the formulated PYFPT (7.96±0.27, 11.17±0.25; 0.81±) than control yoghurt (4.23±0.01, 5.44±0.04, 0.59±0.01). A profile of ash content of the added purple tea puree recorded 16 different mineral salts. The macro minerals were the major, with potassium recording the highest content (282 ppm), followed by sodium (121 ppm), magnesium (97.2 ppm) and calcium (96.4 ppm). The microbial anaerobic probiotic count (6.14 - 6.80 log CFU/ml) was not statistically and significantly different between the PYFPT and the control yoghurt after 28 days of refrigerated storage. In conclusion, the study demonstrated that it is feasible to formulate nutritious probiotic yoghurt fortified using purple-leaf tea puree with potential for commercialization.

The aim of this study was to estimate the quantities of cultivated edible mushrooms (CEM) and wild edible mushrooms (WEM) traded in the Virunga National Park (ViNP) in North Kivu in the Democratic Republic of Congo. Two hundred and sixteen (216) respondents were selected randomly as the sample size and they were divided evenly between growers and gatherers along each of the sites surveyed. The quantitative analysis was conducted using Statistical Package for the Social Sciences (SPSS) 26, at the 5% threshold. On the Beni-Mutwanga and Beni-Mangina axes, nine WEM species were identified in total. On the Goma-Rutshuru axis, there were six species, and on the Goma-Kitshanga-Mweso axis, there were five species. In all locations surveyed, only one species, Pleurotus ostreatus, was recognized by any of the growers. Termitomyces microcarpus had been chosen by fifty percent of respondents. The average yield that was acquired was 359 kg per crop cycle for all growers, while pickers got 78 kg during the short season (the rainy season from March to May) and 130 kg during the long season (the rainy season from September to January). Additionally, mushrooms provide essential nutrients, including selenium, potassium, riboflavin, niacin, vitamin D, proteins and fiber. Given their long history as a food source, mushrooms are of significant importance in traditional medicine due to their healing capacities and properties. It has been demonstrated that mushrooms have beneficial effects on human health and the treatment of certain diseases. A number of nutraceutical properties have been identified in mushrooms, including the prevention and treatment of Parkinson's disease, Alzheimer's disease, hypertension and high-risk stroke. Additionally, they are employed to diminish the probability of cancer invasion and metastasis due to their anti-tumoral characteristics. That is why, the introduction and training of farmers in the production of particular edible mushroom varieties may provide a new profitable annual income. These findings support the wild edible domestication (WED) (cultivation) of wild edible mushrooms in the surveyed areas, with the goal of increasing household income and thus contributing to in the conservation of the ViNP's ecosystems.

Published: December 2024

Livestock farming is a crucial source of income and livelihood. However, its sustainability is being adversely affected by the unpredictable climatic changes. It would be valuable to comprehend how livestock farmers perceive climate change (CC) and the adaptation strategies. This study evaluated farmers’ views of climate change impact, adaptation measures, and the obstacles to these measures. A cross-sectional and multi-stage sampling method was employed. Data collected from 300 randomly chosen farmers were analysed using descriptive statistics and the Garrett ranking technique. Most of the respondents were male (71.67%) and between the ages of 21-60 (62%). Most respondents were married (67%) and had a form of education. Increased disease occurrence, decreased livestock production rate, increased poor vegetation, increased water scarcity, and ambient temperature were perceived by the respondents to have been impacted ‘to a great extent’ by 45%, 38%, 53%, 36% and 42%, respectively. Perceived and rated as ‘to a great extent’ by the respondents on climate change impact were ‘increased distance covered by livestock for water and pasture (29%), decreased growth rate (28%), and increased ambient temperature (30%)’. Based on descending mean rank, the farmers’ most favoured strategies for adapting to climate change included reducing their livestock numbers (58.98), collecting and storing water (55.66) and planning for supplementary feeding (55.35). The income management strategies under CC include off-farm employment (55.48), borrowing from self-help groups (54.48), and friends and relatives (50.72), in that order. The top barriers to CC, in descending order of mean rank, by the farmers include a high incidence of pests and diseases (61.47%), non-availability of improved forage seed (52.06), lack of appropriate water harvesting facilities (51.84), smaller/ fragmented land holding for forage (51.56) and scarcity of farm labour (47.75). The livestock farmers’ perception of climate change impacts indicated that most of the factors examined were rated as significant. Most respondents are aware of climate change (CC) and its repercussions on livestock productivity.

Published: December 2024

Background: Olive byproducts are valuable feed resources for livestock and poultry. The current study aimed to assess the impact of adding olive pomace (OP) to the diet of broilers raised in battery cages with varying stocking densities on their growth performance, carcass characteristicsand blood biochemical parameters. Methods: Sixty-two-day-old unsexed broiler chicks were divided into two treatment groups, each with 31 birds. The first group of 31 chicks were raised in electrically heated battery brooders with varying stocking densities of 8, 16, or 25 birds per m² and fed with a standard diet. The second group of 31 chicks was raised with the same stocking densities and fed with supplementing 5% OP. Result: Increasing stocking density from 8 to 25 birds/m² reduced growth performance, whereas recorded the highest body weight gain with stocking density of 16 birds/m² in commercial broilers. The eviscerated carcass weight, abdominal adipose tissue (AAT)and breast weight decreased by 8.7% with higher stocking densities. The levels of serum creatine kinase (CK) and alanine amino transferase (ALT) increased in contrast to the decrease in glucose. Plasma ALT and AST levels were considerably reduced when OP was added to the broiler diet.

Published: December 2024

Background: This study investigates the differences in rumen fermentation parameters and microbial communities in yaks aged 3 (MarG), 4 (AprG) and 5 months (MayG). As crucial livestock on the Qinghai-Tibet Plateau, optimizing yak health and productivity relies on understanding their rumen microbial structure and fermentation efficiency. These findings provide insights into their adaptation to the plateau environment and support strategies for improving livestock management. Methods: The study analyzed rumen fermentation parameters (NH3-N, acetate, propionate, isobutyrate, butyrate, valerate) and microbial composition in three age groups of yak calves. Microbial richness and composition were assessed, with network and correlation analyses identifying key microbial phyla associated with fermentation. Functional predictions explored gene abundances related to transcription, viral infection, cancer types and the immune system across the groups. Result: NH3-N and acetate levels were significantly higher in the MarG group compared to AprG and MayG (p less than 0.05), while MayG showed elevated propionate, isobutyrate, butyrate and valerate levels (p less than 0.05). Microbial composition varied, with Firmicutes and Actinobacteriota dominating MarG, Christensenellaceae and Oscillospiraceae in AprG and Desulfobacterota in MayG. Network analysis identified Proteobacteria as central in MarG, Firmicutes in AprG and both in MayG, forming the most complex network. UCG-005 showed strong positive correlations with all fermentation parameters. Functional predictions indicated higher cell motility in MarG and more immune-related genes in MayG.

Feldscheune Chrummacher/Rötler – Eptingen, VBF-Inventar Nr. 20/21 – Schlussbericht der Renovationsarbeiten
Authors: Oppler Dominique , Steinemann Jakob , Weber Emmanuel , Zehnder Markus
Published: December 2024

Sie gehören zu den belebenden Elementen unserer Kulturlandschaft, die Feldscheunen, die Heuschober und die Weidställe. Und sie sind gleichzeitig traditionelle Denkmäler wie Kirchen und Pfarrhäuser. Die Scheunen und Ställe stellen zusammen mit den bäuerlichen Wohnbauten unsere regionaltypische Architektur dar. Erbaut wurden die meisten in der Zeit der Dreifelderwirtschaft. Auf dorffernen Grundstücken wurden zu Zeiten des Flurzwangs kleine Heuschober erstellt. Aus diesen wurden dann im Winter das Heu geholt. Auch entstanden Weidställe in höheren Lagen. Oft wurden solche Heuschober von mehreren Mitbesitzern genutzt. Durch die Aufhebung des Flurzwangs entstanden Anfangs des 18. Jahrhunderts die ersten Aussenhöfe. Oft an der Stelle der alten Scheunen und Ställe, dort eben, wo auch Quellen in der Nähe waren. In der weiteren Entwicklung des Landwirtschaftsbetriebe siedelten immer mehr Höfe aus und bauten grosse Scheunen. Die Mechanisierung in der Landwirtschaft brachten ebenfalls einen grossen Schub an Rationalisierung und diese Maschinen konnten nicht in den alten Scheunen unterbracht werden. Die alten Bauten brachten und bringen somit kaum einen Nutzen für die Landwirte. Sie sind eher, bedingt durch notwendigen baulichen Unterhalt, eine finanzielle Last. Für viele sind Feldscheunen emotionale Orientierungspunkte in der Landschaft. Jedes Mal, wenn eine verschwindet, verschwindet ein Stück Landschaft in der Erinnerung. Der Verein Baselbieter Feldscheunen hat sich zum Ziel gesetzt, Wege zum Erhalt dieser wertvollen Kleinbauten zu finden. Dabei legt der Verein die Priorität auf die besonders schützenswerten Scheunen und Ställe. Solche, die durch ihre besondere Lage, durch ihre Geschichte und durch besonders eindrückliche handwerkliche Bauteile und Konstruktionen herausragen. Damit will der Verein dieses geschichtliche bäuerliche Kulturerbe schützen und auch im Bewusstsein wach halten. Pro Jahr soll mindestens eine Feldscheune renoviert werden.
Accelerating convergence of Newton-type methods to singular solutions of nonlinear equations
Authors: Izmailov Alexey F. , Uskov Evgeniy I.
Published: December 2024

We consider the simplest extrapolation procedure, specifically doubling the step, intended for acceleration of convergence of Newton-type methods to singular solutions of smooth nonlinear equations. We demonstrate that the acceleration effect of this procedure can be different for different Newton-type methods. For linear-quadratic equations we provide theoretical results yielding quantitative estimates of the potential effect of extrapolation for the Newton method, for the Levenberg–Marquardt method, and for the recently proposed LPNewton method, in some sense explaining the observed difference. Theoretical analysis relies on interpretation of these methods as a perturbed Newton method with the appropriate estimates of perturbations, as well as on sharp results yielding a quantitative characterization of a step of such perturbed method, and its local convergence at a linear rate to singular solutions satisfying the 2-regularity condition in a direction from the null space of the first derivative. Furthermore, we perform numerical experiments with globalized versions of the algorithms in question, equipped with choosing the stepsize parameter, on two sets of test problems. Experimental observations confirm the theoretical results, and also demonstrate that in cases when the equation contains nonlinear and nonquadratic terms, the effect of extrapolation is evened out.

continuous linear operators on ultrametric Banach spaces and we introduce and study the operator equations ASB=S and AS=SB. We give some properties of these operator equations. Some illustrative examples are provided. On the other hand, we introduce and study the left (right) pseudospectrum and the left (right) condition pseudospectrum of continuous linear operators on ultrametric Banach spaces. We prove that the left pseudospectra associated with various ε>0 are nested sets and the intersection of all the left pseudospectra is the left spectrum. We give a relationship between the left (right) pseudospectrum and the left (right) condition pseudospectrum. Moreover, many results are proved concerning the left (right) pseudospectrum and the left (right) condition pseudospectrum of continuous linear operators on ultrametric Banach spaces.

Published: December 2024

A truck dealership company, specializing in maintenance, repair, and spare parts sales, faces stockout challenges that hinder its ability to meet demand for moving code 1 spare parts. The absence of effective forecasting methods and safety stock policies exacerbates these issues. This study aims to optimize inventory management by identifying suitable forecasting methods and implementing the Continuous Review System (CRS) to establish safety stock and reorder points as the parameter for procurement planning. The results indicate that the Double Exponential Smoothing (DES) method effectively predicts demand, while the Monte Carlo simulation method performs better for spare part 493051110L. The CRS approach improves the fill rate and reduces stockout risks, ensuring better inventory management for the company. These findings provide a framework for the company to enhance its spare parts inventory strategy, contributing to improved service reliability and operational efficiency.
Characteristics of halal gelatin from spanish mackerel (Scomberomorus commersonii) bone gelatin isolated with bromelain enzyme pretreatment
Authors: Hanif Anisa , Afifah Ika Qurrotul
Published: December 2024

In this research, gelatin was isolated and characterized from mackerel fish bone (Scomberomorus commersonii) by varying the bromelain enzyme concentration as an alternative source of halal gelatin. This study aimed to detect the presence of typical gelatin absorption in the FTIR (Fourier Transform Infrared Spectroscopy) spectrum of products isolated from mackerel fish bone waste and to analyze the effect of bromelain enzyme on yield, pH, water content, ash content, and gelatin protein content. Pretreatment processes were carried out using enzymes with variations of 0; 1; 1,5; and 2% for 6 hours, followed by a 13% citric acid solution for 96 hours. Extraction was conducted using distilled water as a solvent heated at 75oC for 6 hours. The gelatin solution was concentrated for 24 hours and dried for 48 hours in an oven at 60oC. Characterization using FTIR spectrophotometer indicated the presence of gelatin absorption bands such as Amide A, Amide I, Amide II, and Amide III. Gelatin isolated from mackerel fish bone had a yield ranging from 3,64-7,57%, pH values of 3,88-5,15, water content of 7,63-10,19%, ash content of 2,19-5,92%, and protein content of 65,68-88,47%. An increase in yield of up to 50% compared to the yield of non-enzymatic gelatin occurred when the enzyme bromelain was added at 1.5% in the pretreatment process. The characteristics of mackerel fish bone gelatin meet the requirements of GMIA (2012) and SNI (1995), however, for the ash content, only the addition of 1,5% enzyme met the standard. The yield, pH, water content, ash content, and protein content of mackerel fish bone gelatin were significantly influenced by the concentration of the bromelain enzyme used.

Climb of the Chaplygin Sleigh on an Inclined Plane under Periodic Controls: Speedup and Uniform Motion
Authors:   Udmurt State University, Bizyaev I. A. ,   Udmurt State University, Vetchanin E. V.
Published: December 2024

This paper addresses the problem of the Chaplygin sleigh moving on an inclined plane under the action of periodic controls. Periodic controls are implemented by moving point masses. It is shown that, under periodic oscillations of one point mass in the direction perpendicular to that of the knife edge, for a nonzero initial velocity there exists a motion with acceleration or a uniform motion (on average per period) in the direction opposite to that of the largest descent. It is shown that adding to the system two point masses which move periodically along some circle enables a period-averaged uniform motion of the system from rest.

SUHRAWARDĪ’S CONCEPT OF ILLUMINATION AND ITS RELEVANCE TO ENVIRONMENTAL CONSERVATION AWARENESS
Authors: Ihsan Nur Hadi , Mudin Moh. Isom , Dewantara Mawardi
Published: December 2024

This study investigates Shihāb al-Dīn al-Suhrawardī's sufi philosophy of illumination and explores its potential contribution to contemporary environmental consciousness. The increasingly urgent global ecological crisis has sparked interdisciplinary debate about root causes and comprehensive solutions. Several contemporary thinkers argue that the ecological crisis is a manifestation of a more fundamental ontological crisis, namely the loss of humans' harmonious relationship with nature. In this context, Islamic philosophy, especially the school of illumination (ishrāq) developed by Shihāb al-Dīn al-Suhrawardī, offers a unique perspective that can enrich environmental discourse. The research aims to integrate Suhrawardī’s ontological and epistemological concepts with contemporary ecological principles to offer a novel perspective on human-nature relationships. A descriptive-analytical approach is employed to analyze Suhrawardī’s philosophical texts and correlate them with modern ecological theories. The study reveals that Suhrawardī’s concept of asala al-mahiya (essential reality) and his illuminationist epistemology, which views all beings as emanations of divine light, challenge the anthropocentric worldview. This perspective promotes two fundamental ecological principles: biospherical illuminative egalitarianism and illuminative equilibrium. These principles emphasize social justice and environmental balance, recognizing humans as integral parts of nature with responsibility for its preservation. By shifting the human-nature relationship from a subject-object dichotomy to an inter-subject interaction, Suhrawardī’s philosophy can enhance awareness of environmental issues and inspire more sustainable practices. Integrating spiritual wisdom and ecological consciousness offers a holistic approach to addressing contemporary environmental challenges.

This study aims to develop educational models for patients and families with hypertension. A sequential mixed-method research design was used. Focus group discussions and in-depth interviews were conducted with 28 participants to explore the phenomenon and health education needs of patients and families with hypertension, and the data were analyzed thematically. A survey of 40 people was conducted to identify the elements of a workable model using SEM analysis. The researchers then used an integration matrix to perform the data integration. Seven themes were revealed from the qualitative phase: (1) health problems, (2) scope of educational services, (3) primary service activities, (4) health education methods, (5) information needs, (6) management support, and (7) barriers. The following sub-components were also obtained from the analysis: (1) Health Education Approach, (2) Health Education Program, and (3) Learning Process. The educational model for patients and families with hypertension is complex, and nurses require support to implement such a model. Further research is needed to prove the model’s effect on the personal and interpersonal conditions of hypertensive patients.

This study aimed to analyze the chemical components and antibacterial activity of essential oils from kamboja (Plumeria alba L.), sedap malam (Polianthes tuberosa L.), and kenanga (Cananga ordorata L.) flowers against Staphylococcus aureus ATTC 25923. Additionally, the study explored the application of these essential oils as bio additives in transparent solid bath soap. The research consisted of several stages: isolation and identification of chemical components of essential oils using the GC-MS Method, transparent solid bath soap formulation, antibacterial activity test of essential oils and transparent solid bath soaps against Staphylococcus aureus ATTC 25923, organoleptic test (color, aroma, transparency, solidity, and foam) and quality test of transparent solid bath soaps (pH, water content, foam stability, saponification number, and transparency). The essential oils extracted from kamboja, sedap malam, and kenanga flowers were found to contain 17, 20, and 20 compounds, respectively. Based on the result of GC-MS analysis showed that the predominant chemical components in each essential oil were 1,1’-oxydi-2-propanol (21.01%) for kamboja, benzyl ethanoate (24.52%) for sedap malam, and caryophyllene (43.77%) for kenanga. Transparent solid bath soaps with the highest antibacterial activity against S. aureus ATTC 25923 were obtained in the formula added with kamboja, sedap malam and kenanga flowers essential oils at 3.0%, 3.0%, and 3.0%, respectively, with respective inhibitory power of 14.48 mm (strong), 13.73 mm (strong) and 13.56 mm (strong) in diameter. Organoleptic tests revealed that each soap type exhibited characteristic of the respective flower. All soap types demonstrated good quality based on parameters such as pH, water content, foam stability, saponification number and transparency.

The main organ that of the urinary system after the main organ functions to filter waste products from the body's metabolism that must be removed through the excretion process is the kidneys. The remaining metabolite compounds that accumulate in the blood are caused by the kidneys being unable to filter and remove uremia toxin compounds such as urea and creatinine from the body. One indication of kidney damage can be seen from levels of creatinine and urea in the blood that exceed normal limits. Urea and creatinine levels can be lowered by improving kidney function, namely by the blood washing process (hemodialysis). In the hemodialysis technique, the price of an artificial kidney or hemodialyzer is very expensive so that kidney failure sufferers require very large costs for treatment. To overcome this problem, alternative natural materials are needed to make membrane artificial kidneys. The aim of the research is (1) to analyze the synthesis and characteristics of membranes and, (2) to apply them for the transport of creatinine and urea using silica chitosan membranes. Characterization includes functional group testing using an Fourier-Transform Infrared (FTIR) spectrophotometer, water absorption test (swelling test), tensile test, and morphology with Scanning Electron Microscope (SEM). The membranes were applied for creatinine transport with varying concentrations of 70, 100, and 130 mg/L. It was also used for transporting urea at various concentrations of 500, 1000, and 1500 mg/L. This study disclosed a window of opportunity to produce novel hemodialysis membranes using bio-based materials.

A study on the synthesis of magnetized adsorbents from coal fly ash (FA) for the adsorption of malachite green (MG) dye has been conducted. The method involves acid activation and ferrite magnetization of FA. The activation of FA was performed by mixing it in an HCl solution, while the magnetization was carried out by the coprecipitation method using the molar ratio of 1:2 of Fe2+/Fe3+. The magnetized coal fly ash adsorbent (FA/Fe3O4) was then utilized to adsorb the MG dye, and the results were compared with that adsorbed by activated fly ash (AFA). Characterization of the materials was carried out using Atomic Absorption Spectroscopy (AAS), Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), and Vibrating Sample Magnetometer (VSM). The optimized parameters in the adsorption study were pH, adsorbent mass, contact time, and initial concentration. The optimum conditions for the adsorption of MG dye with AFA and FA/Fe3O4 are obtained at pH 7, the adsorbent mass of 0.1 and 0.25 g respectively, a contact time of 45 minutes, and the initial concentration of MG dye of 175 ppm. The MG adsorption on both adsorbents follows a pseudo-second-order kinetic model and can be best described by the Langmuir isotherm adsorption model. The synthesized adsorbent is prospective as it is low cost and easily separable from the solution using an external magnet after adsorption.

Polyethylene glycol (PEG) ester is a non ionic surfactant compound that could use a pour point depressant (PPD) for crude oil. Synthesis of PEG-ester with reflux and mono wave-50 methods through esterification fatty acid such as oleic acid, stearic acid, and palmitic acid with adding p-toluene sulfonic acid (p-TSA) as a catalyst. The product of esterification could be a mixture of monoester and diester. Synthesized PEG ester by reflux method resulted in higher yield than by mono wave-50 method. IR spectra analysis of PEG400-oleate, PEG400-stearate, and PEG400-palmitate show the presence of an absorption band at a wavenumber of around 1100 cm-1 that indicates the stretching vibration of the C-O ester. (LC-MS/MS) analysis that shows the molecular weight of PEG400-oleate was 845.6154 g/mol and, PEG400-stearate was 785.5952 g/mol. Mean, while PEG400-palmitate produced three ester compounds with different molecular weights: 741.5669 g/mol, 685.5057 g/mol, and 734.5208 g/mol. The pour point measurement results show that the PEG-fatty acid product in the range of 0.1% to 1% has not been able to reduce the pour point of the crude oil sample.

In 2023, the waste production in D.I. Yogyakarta Province reached 440,267.76 tons per year, with household waste contributing the largest portion at 44.3% of the total. The continuous rise in waste is attributed to the increasing population and declining quality of life. Additionally, the local community's lack of awareness about effective waste management, such as composting food waste, exacerbates the problem, making it difficult for them to handle the waste they generate. This initiative aimed to educate the Padukuhan Sawit community, particularly RT.002, on household-based waste management practices. It included discussions and hands-on training on how to use mini composters. The methodology involved a field survey, discussions with community leaders, preparation and planning, socialization, distribution of mini composters, and an evaluation and demonstration of the proper use of mini composters. The program, conducted over two sessions, garnered significant enthusiasm from the participants. Out of the 10 mini composters distributed, only 4 were used independently. The main barrier preventing wider adoption was the fear of failure, such as unpleasant odors or other technical issues. Therefore, there is a need for strategic follow-up and mentoring to ensure the sustainability of the initiative. Such as monitoring each representative of the dasa wisma and distributing spare EM4 fluid to facilitate waste management for other residents.
