The success of IPB student's study can be seen from the achievement index obtained at the end of each semester. Meanwhile, the success rate of one's study is generally influenced by two factors, internal factors and external factors. Internal factors consist of intelligence (intellectual), physical, attitudes, interests, talents, and motivations, while external factors consist of family circumstances, school conditions, and the community environment. Therefore, this study uses the analysis method of classification and regression trees (CART) to find out what factors influenced the success of the Student Council (OSIS) university students.
Regression tree it is one of the methods of classification and regression trees (CART) to perform classification analysis on both categorical and continuous response variables. Continuous response variables will produce a regression tree or hierarchical data group that starts at the root and ends with a relatively homogeneous small group. The response variable used in this study is the Achievement Index of first semester students. The results obtained from the analysis showed that there are several different variables in each class in influencing the success of the student council (OSIS) university students, but if we look further, there are two variables that are the same in influencing the success of the student council (OSIS) university students, which are variables from high school province and student study programs.
This study uses secondary data from 493 IPB students track the chairman of the student council of the year 2018-2020 which is still active until now. Furthermore, the analysis of the regression tree is performed against four different models, for each of the force and the overall force by adjusting the variables available. The formation of tree regression performed 10 repetitions and the results of regression trees is taken from a tree which has the approximate value of the smallest risk. Then, the final results obtained from the analysis showed that there are several different variables in each class in influencing the success of the student council (OSIS) university students, but if we look further, there are two variables that are the same in influencing the success of the student council (OSIS) university students, which are variables from high school province and student study programs.

Indonesia is ranked fourth in the world as the country with the largest population. The high population growth in Indonesia can cause problems in several fields. The government seeks to suppress the rate of population growth through the Family Planning (KB) program. In Indonesia, the number of unmet needs for family planning is still relatively high and has not yet reached the BKKBN target. Therefore, it is necessary to identify the characteristics of unmet need for family planning among married women or living with partner. This study used the Classification and Regression Trees (CART) method. This study handling unbalanced data by Synthetic Minority Oversampling Technique (SMOTE). This study aims to compare the performance of the CART and SMOTE CART classification methods in classifying unmet need for family planning and to identify the characteristics of unmet need for family planning among married women or living with partner in Indonesia. The SMOTE CART model has better performance than the CART model, with the percentages of balanced accuracy, sensitivity, and specificity being respectively 54.83%, 34.96%, and 74.70%. In general, the characteristics of unmet need for family planning among married women or living with partner in Indonesia are having 1-4 living children, not getting information from mass media, not accessing the internet in the last month, having a primary or secondary education level, a husband with no education or with a primary or secondary education level, and aged more than 30 years old.

Diabetes mellitus and hypertension are common diseases affecting a lot of people. Alpha amylase and angiotensin-converting enzyme (ACE) inhibitors are used to treat type II diabetes and hypertension respectively. This study investigated the alpha amylase and ACE inhibitory potential of Azanza garckeana fruits. Phytochemical screening, α-amylase and ACE inhibitory potential of the aqueous extract of A. garckeana fruit was determined using standard procedures. The mode of inhibition of α-amylase by A. garckeana fruit was determined from the Lineweaver-Burk plot. Alkaloids, flavonoids, anthraquinones, steroids, tannins, phenols and terpenoids were present in the aqueous extract of A. garkeana fruit. The percent inhibition of α-amylase was greater than 50%. The IC50 values were 2.6 ± 0.02 and 0.04 ± 0.09 for the extract and acarbose (standard drug) respectively. The Lineweaver-Burk plot showed that extract Vmax did not change when compared to the no inhibitor (no extract) but the km increased. The percent inhibition of ACE by A. garckeana was also greater than 50%. Its IC50 was 0.625 ± 0.03 while that of the standard drug (captopril) was 0.875 ± 0.07. Thus A. garckeana inhibited α-amylase and ACE and can be used to treat type II diabetes and hypertension. It is a competitive inhibitor of α-amylase.

Dyes harm both aquatic species and humans in wastewaters, which are poisonous as well as carcinogenic. For decades, the adsorption system technique has been widely used to take out dyes from aqueous solutions since it is a trouble-free and successful process. The present study investigated the use of Euphorbia hirta’s leaf powder/stem powder/leaf ash/stem ash for the adsorption of methyl red dye (MRD) from aqueous samples for the first time. MRD aqueous solutions (250 ml, 100 ppm) were incubated for the required contact period with 1.2 gm/l of investigated sorbent with agitation at 100 rpm. The temperature and pH remained maintained at 27 degrees Celsius and 4.0, respectively. The residual amounts of MRD were evaluated by spectrophotometrically measuring MRD absorbance at 464.9 nm. The percent MRD clearance using E. hirta’s leaf powder/stem powder/leaf ash/stem ash showed that the optimal condition of MRD clearance happened at pH unit of 4, 100 ppm concentration of MRD, sorbent dose at 1.2 gm/l, ambient temperature, mechanical shaker agitation speed of 100 rpm. The optimal equilibration time for highest percentile MRD clearance was 125 min (E. hirta leaf powder), 105 min (E. hirta leaf ash powder and E. hirta stem powder) and 90 min (E. hirta stem ash powder). Negatively charged chemical groups like –COOH, -CHO, -NH, etc. present in the phytochemicals of E. hirta’s leaf and stem binds to positively charged ions in MRD, as a result, adsorption occurs. For its significant biosorption potential and cheap cost, E. hirta’s leaf powder/stempowder/leaf ash/stem ash can be regarded as alternative biomass for removing MRD from the aqueous solution.

Published: June 2022

One of the global health issues is antibiotic resistance in Pseudomonas aeruginosa, a causative agent of bacterial infections due to multidrug resistance (MDR), which may be mediated by efflux pumps' overexpression.The present study investigated the prevalence of mexXY-oprM, mexPQ-opmE genes as encoding agents of efflux pumps and the determination of antibiotic resistance rate in clinical isolates of P. aeruginosa.Different clinical specimens of infectious patients, such as wounds, urine, blood, discharge, and abscesses except for stool, were examined. Identification of the isolates was performed using Pseudomonas chromogenic agar. A selective medium for the isolation of P. aeruginosa, used to screen 79 isolates. The results were validated by Polymerase chain reaction (PCR) utilizing particular primer pairs for the 16S rDNA gene of Pseudomonas spp. for identification of the isolates after incubation at 37°C for 24 hours. According to Clinical and Laboratory Standards Institute (CLSI) (2021) recommendations, a microbial susceptibility test was performed using the Kirby–Bauer disk diffusion method. P. aeruginosa was extremely resistant to ceftazidime (93.6%) and cefepime (77.2 %). In contrast, imipenem (77.2%) and meropenem (67%) showed high sensitivity. Finally, mexXY-oprM, mexPQ-opmE genes were investigated by PCR technique. Molecular investigation revealed mexX 43%, mexY 51.89%, oprM 48.1%, mexP 36.70% mexQ 46.83% and opmE 51.89%. The present study concluded that mexXY-oprM and mexPQ-opmE may have a role in P. aeruginosa resistance to various antibiotics. Identifying resistant isolates and antibiotic monitoring programs is essential to prevent the spread of MDR isolates.

The central oscillator is located in mammals' suprachiasmatic nucleus (SCN). The liver is the non-photic organ and the centre for metabolic activities. Food could be a potential zeitgeber for the liver as the timing of feeding is precise in animals. The present study hypothesized that the food provided at a different time of the day (consistently delay of 6 hours) could lead to the desynchronization of daily rhythms in clock genes in liver tissues. The Winstar albino rats were divided into three groups and were exposed to a daily light-dark cycle (12L:12D; 12h light and 12h dark). The Group 1 (Control group) had food ad libitum, Group 2- second group- 6h food group had daily food availability of 6h (night fed group). In contrast, Group 3- T30 group was provided food for 6 hours but delayed by 6h from the previous day's food timing. After 30 days, animals were sacrificed at six-time points and the expression of clock genes was studied in the liver. Food cycle's effect was observed on body mass, and it was significantly (P < 0.05) reduced in the T30 group. The circadian clock persisted in both food ad libitum and night fed groups but changed in phase and amplitude. However, it lost daily rhythm in clock genes in liver tissues of the T30 group. These results are significant as they suggest that the food's timing is critical for synchronizing the circadian clock in the metabolic center, i.e., the liver.

In order for plants to perform well in nutrient-deficient calcareous soils, they have an efficient adaptive technique of root exudate secretion, which contains low molecular weight organic acids. They enhance nutrient release and thereby increase the nutrient availability in calcareous soils. The present study aimed to investigate the effect of concentration and time of incubation of low molecular weight organic acids on P solubilization from calcareous soils collected from various locations of Coimbatore district with varying levels of calcareousness. An incubation experiment was conducted with five calcareous soils with varying levels of free CaCO3 viz., (1, 7.5, 12.5, 17.5 & 21.5%) by incubating with seven different concentrations (0, 20, 40, 60, 80 & 100 mM) of four organic (citric, malic, oxalic and acetic acid) and two amino acids (glycine and lysine) for nine incubation time intervals (5, 10, 20, 30, 60, 120, 240, 960 & 1440 mins) on a factorial experiment based on completely randomized design (CRD). Available P was analyzed to find the solubilization efficiency of various organic and amino acids. The organic acids were more efficient when compared to amino acids in P solubilization, especially citric acid followed by oxalic and malic acids, at 100 mM concentration incubated for 1440 mins. Also, the solubilization increased with increasing concentration and incubation time, irrespective of the soil calcareousness, but the magnitude of phosphorus extraction decreased with increasing soil calcareousness. Incubating the calcareous soils with 100 mM of citric acid for 1440 min solubilized more amount of phosphorus. Hence it can be concluded that addition of 100 mM citric acid will influence the phosphorus release even from highly calcareous soils.

Antagonistic bacteria contribute to the management of plant diseases by stimulating the natural defenses in the host and/or by ensuring direct biocontrol of the aggressors. The objective of this work was to isolate, identify and evaluate (in vitro) various Bacillus spp. for their potential to control phyopathogenic fungi. Selection of the 40 strains of Bacillus previously isolated from the soil in various areas of western Algeria was carried out by direct confrontation on the mycelial growth of four phytopathogens (Fusariumoxysporumf.splycopersici, Alternaria tenuis , Phytophthorainfestans, Ascochytapisi). This strategy involved using the antagonistic potential of microorganisms found in the plant environment in Algeria. The second part of this work consisted of the characterization and identification of tested strainsThe identification of the selected strains was carried out by biochemical tests. The results obtained showed that at the end of the fifth day, the most promising isolates showed antifungal activity and reached an inhibition rate of the mycelial growth of phytopathogenic fungi, respectively, F. oxysporumf. splycopersici 75%, A. tenuis 80%, P. infestans 83.30%, Ascochytapisi 67%. The potential antagonist of Bacillus tested in vitro by direct confrontation against 04 phytopathogenic fungi showed that all strains of Bacillus decreased fungal mycelial growth. Two strains of Bacillus B30 and B41 were found to have the most efficacy against Fusarium oxysporum f.sp. lycopersici, Alternaria tenius, Phytophtora infestans et Ascochyta pisi, with an inhibition rate of 65.25 and 72.25% respectively These results demonstrate that Bacillus sp. presenteds a potential for biological control. However, it is important to understand the mechanisms implemented by these bacteria to develop effective protection strategies.
I have spina bifida and what this means to Malaysia
Authors: Abdul-Aziz Noraishah Mydin 
Published: June 2022

In December of 2002, the Malaysian government sent one very highly opinionated individual with spina bifida to do her PhD on her medical condition at University College London (UCL). Truth be told, in retrospect, during the phone interview with Professor Andrew J. Copp, this particular Malaysian student was not aware that her would-be PhD supervisor at that time most likely may not have considered the extent of the severity of her disability and the extent of having to deal with an individual with needs, different from other postgraduate students. UCL and England, being champions of equal opportunity, the focus during the London-Kuala Lumpur phone interview was entirely on her laboratory experience. The individual knew one thing and one thing alone, that she wanted to be regarded as capable purely on the basis of her academic abilities, and keenness on the topic and that she knew she had a huge plus on her side, that the Malaysian government would finance her studies (being of Bumiputera status by virtue of her mother's ethnicity) and having passed all the relevant exams and that all she needed to do was to make the case to procure a PhD studentship from a top global university.

Philosophy as a Way of Life as a Pathway to Recovery for Addicted Individuals
Authors: Du Plessis Guy 
Published: June 2022

In this essay I address the notions of motivation and self-deception by exploring the value of philosophy in the context of addiction treatment. More specifically, in this essay I explore the notion of philosophy as a way of life as a recovery pathway for individuals in addiction recovery. My hypothesis is that philosophy as a way of life can be a compelling, and legitimate recovery pathway for individuals in addiction recovery, as one of many recovery pathways. I will focus on logic-based therapy (LBT) applied in the context of addiction recovery. The aim of presenting a case study is to show how a client receiving LBT is provided with techniques and a worldview that can contribute to a philosophically oriented recovery program. In the case study the client was advised to apply the moral philosophy of Friedrich Nietzsche as an uplifting philosophical framework to counteract his unproductive worldview and fallacious thinking. Considering that there is an ostensibly low efficacy rate for the treatment of addiction, articulating the value of philosophy as a way of life as a recovery pathway provides a conceptual and methodological framework for the development of novel philosophically-based addiction treatment and recovery-oriented programs–thus expanding the treatment and recovery options available for those seeking recovery from addiction.
