<![CDATA[The high maternal mortality rate (AKI) is still not resolved properly because AKI in 2018 is still high at 305/100,000 live births,maternal deaths often occur during nifas. To overcome AKI during nifas period one of them by visiting nifas. One of theaffecting factors is knowledge. The covid-19 pandemic that hit the entire country affected nifas's visit to the Health ministry.The purpose of this study is to analyze the relationship of nifas mother's knowledge with attitudes about nifas visits duringthe covid-19 pandemic. The design of this study is cross sectional with analytical surveys. The study sample was 38 in April-May 2019. Sampling technique is total sampling. Analyze the data using the chi-square statistic test. The results found thatout of 15 people (39.5%) who have a bad attitude there are 9 people (81.8%) have less knowledge about nifas visits duringthe covid-19 pandemic. And of the 23 people who have a good attitude there are 14 people (87.5%) who have sufficientknowledge with a value of p 0.001 then can be interpreted that there is a significant relationship between knowledge and theattitude of the mother nifas about nifas visits during the covid-19 pandemic.

<![CDATA[Wood is the material most widely used in human life. The high demand for wood requires an alternative that can replace thefunction of wood, especially in the particleboard industry. As a material that contains biomass, sludge waste from pulp andpaper industry has a great potential to be used as raw material for making particleboard. The use of sludge waste as rawmaterial for making particle boards can also reduce the impact of environmental pollution. In particleboard manufactures,additives are needed to improve the quality of particleboard. Additives used can be in the form of an adhesive or a matrix. Inthis literature study, we will review the effects of pressure, temperatur, and adhesive types on the physical and mechanicalproperties of the resulting particleboard. Physical properties to be reviewed in the form of water content, density, andthickness development, while mechanical properties to be reviewed in the form of modulus of elasticity (MoE), modulus ofrupture (MoR), and tensile strength. The physical and mechanical properties obtained will then be compared with SNI 03-2105-2006 which is the national standard for particleboard products. In this literature study, it was found that the optimumpressure and temperature ranges for the manufacture of particleboard are 30 kg/cm2 and 180oC respectively. Utilization ofbio-based adhesives such as citric acid and lignin is known to be able to produce particleboard that fulfill SNI 03-2105-2006standards so that it can be used to reduce the use of chemical-based adhesives.]]>

<![CDATA[The aim of this study is to provide directions regarding the potential of cellulose-based natural materials as cationicbiopolymer flocculants and to provide an economic view regarding flocculation. The conclusion from the study is that thesource of cellulose is abundant in nature. However, the limitations of cellulose’s utilization require modifications of thesurface. The production of cationic cellulose flocculants must pay attention to the value of the degree of substitution (DS)because it will affect the solubility properties of cellulose which shows whether or not it is easy to use in solution for theflocculation process. In addition, chemical understanding of the structure of cellulose is important to make modificationsaccording to the needs. From an economic point of view, flocculation is still a superior choice in terms of energyconsumption, especially in large volumes. However, it is important to add the study of operational costs related to flocculants,including raw materials for flocculant production, ease of production of flocculants, dosage and costs of flocculants.]]>

<![CDATA[This study aimed to determine the acid levels produced in fermented liquid tofu waste using Bacillus subtilis quantitatively.This study began by growing Bacillus subtilis on LB (lactose Broth) media as a positive control and for negative control on LBmedium with variations of 1: 1 and 1: 3 for LB and tofu waste media and liquid tofu waste media only. In the beginning, liquidtofu had already had an acidic level due to the use of acetic acid as a clot. For this reason, it was carried out to check theacid level with the titration process first. Measurement of acid levels for fermentation results is carried out using titration. Inthis experiment, the bacteria growth, specific growth rate and reduction rate of reducing sugars from each of the four mediawere used. Measurement of growth and reducing sugar using a spectrophotometer. From the results of data processing, itwas found that acid concentration increased from the beginning before fermentation and after fermentation. In tofu wastemedia, acid concentration increased from 1.3M to 1.7M; tofu waste compared to LB 1: 3 from 1M to 1.3M; the tofu wastecompared to LB 1:1 from 0.85M to 1.1M and LB media from 0.5M to 0.6M. From these results, it can be seen that the highestincrease in acid concentration is found in tofu waste media.]]>

<![CDATA[Wound healing is a vital procces. Therefore it should be treat carefully which cause the wound to healing well. There areseveral ways to precipitate the wound healing whether is systemic or local. Unify the edges of the wound could be done bysuturing. The small wound could be heal by it self without any infection. Coffe seeds countain chlorogenic acid. Chlorogenicacid have some important benefits such as antioxidant, antibacterial, and also can precipitate the wound healing. Coffeseeds could be used in the wound which cause it to dry faster and not cause any inflammation. To compare the effectivity ofwound healing using robusta coffe seeds and povidone iodine in wound incised healing in mus musculus. This study uses anexperimental method that is designing a post test with a design control group to compare wound utilization using robustacoffee and povidone iodine to the treatment of incision in mice. The average speed of wound healing, coffee had the fastesttime of 6.56 days followed by povidone iodine 10.56 days, while controls were 11.67 days. In terms of effectiveness, Robustacoffee is more effective than controls, namely 8.4: 8. Povidone iodine is no more effective than control ie 8: 8 and after thesignificance test the results are not significant.
