Development of bambangan (Mangifera pajang) carbonated drink
Mangifera pajang Kostermans or bambangan is a popular fruit among Sabahan due
to its health and economic values. However, the fruit is not fully commercialized since it is
usually been used as traditional cuisine by local people. Thus, development of bambangan fruit
into carbonated drink was conducted to produce new product concept. The objectives of this
study were to conceptualize, formulate, evaluate consumer acceptance, and determine
physicochemical properties and nutritional composition of the accepted product. Method used
in conceptualising the product was based on questionnaire. The consumer acceptance was
evaluated based on descriptive and affective tests with four product formulations tested. The
physicochemical properties on carbon dioxide volume, colour, pH, total acidity, total soluble
solid (TSS) and viscosity were highlighted, meanwhile nutritional composition on fat, protein,
carbohydrates and energy content were determined. About 77% respondents gave positive
feedback, and 69% respondents decided this product is within their budget. The formulation of
5% bambangan pulp, 70% water, 25% sugar and 0.2% citric acid was highly accepted in
descriptive and affective tests with 4.4 and 6.39 mean scores, respectively. The
physicochemical properties and nutritional composition of the acceptance product were in
optimum value except for colour, total acidity and TSS. Overall, this study showed that the
product has high potential to be commercialized as new product concept, and heritage of
indigenous people can be preserved when this fruit is known regionally
Analisis Pengaruh Program Makmur Terhadap Peningkatan Produksi Usahatani Padi
Rice is the basic food product consumed by every Indonesian citizen. Tempuran and Pedes sub-districts are the areas that contribute to the highest rice production in Karawang Regency. The instability of rice production in Karawang Regency is due to problems such as the narrowing land area due to land conversion, limited use of subsidized fertilizers, and expensive pesticide prices. The Makmur programme is one form of effort to overcome rice production problems. This study aims to analyze the effect of land area, seeds, fertilizers, pesticides, labour, machinery, and the Makmur program dummy on rice production. The research method used in this research is the descriptive quantitative method. The data collection method was carried out by interviewing and observing all participants of the Makmur programme. The data were processed using IBM SPSS 26 and analyzed using the multiple regression analysis method with cobb-douglas production function. The results showed that: the production of all variables had a significant effect, and partially the variables in the regression calculation before the Makmur program, namely the variable labour (lnX5) and machine power (lnX6) had a significant effect on rice production (Y). In the regression calculation after the Makmur program all variables, namely land area, (lnX1), seeds (lnX2), fertilizer (lnX3), pesticides (lnX4), labour (lnX5) and engine power (lnX6), do not have a significant effect on rice paddy production (lnY). In the regression calculation with the Makmur program dummy, namely pesticides (lnX4) and labour (lnX5) have a significant influence on the dependent variable or rice paddy production (lnY).Padi merupakan produk pangan dasar penduduk di Indonesia yang dikonsumsi setiap.

Antiproliferative activity of five garcinia species collected in Sabah, Malaysian Borneo against estrogen receptor-human breast carcinoma (MCF-7) cell line
Garcinia species are well-known for their unique properties of having natural
secondary metabolite compounds called xanthone as well as their ethnomedicinal values such as
antioxidant, anticancer, anti-inflammatory and antibacterial properties. The study was conducted
to investigate the antiproliferative activity of peel, flesh and seed extracts of G. dulcis, G.
parvifolia, G. nitida, G. mangostana var. mangosta and G. cambogia collected from Malaysian
Borneo (Sabah) against estrogen receptor-positive human breast carcinoma (MCF-7) cells. The
antiproliferative activity was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-
diphenyltetrazolium bromide (MTT) assay. The results showed that G. dulcis seed induced
strongest antiproliferative activity against MCF-7 cancer cell line with the IC50 value of 2.5±0.0
μg/ml, followed by G. dulcis flesh, G. mangostana var. mangostana peel and G. dulcis peel with
IC50 values of 9.33 ± 3.21, 11.17 ± 1.04 and 17.67 ± 2.08 μg/ml, respectively. Meanwhile, the
IC50 value for G. cambogia peel was 56.67 ± 10.5 μg/ml. No IC50 value was detected in all parts
of G. parvifolia and G. nitida at concentration tested (<100 μg/ml). Overall, this study clearly
showed that the whole fruit of G. dulcis displayed potent cytotoxic effect by inducing
antiproliferative activity at low concentration. Further studies are needed in the future to develop
this fruit as pharmaceutical and nutraceutical product for the treatment and prevention against
cancer

Effectiveness of different cleanup sorbents for the determination of avermectins in fish by liquid chromatography tandem mass spectrometry.
An effectiveness and comparative study of cleanup sorbents used in dispersive solid phase extraction (DSPE) for the determination of avermectins, including emamectin (EMA), abamectin (ABA), doramectin (DOR), moxidectin (MOX), and ivermectin (IVE), was performed. Three different types of cleanup sorbents, alumina (Al), primary and secondary amine (PSA) and octadecyl (C18), were used to remove the matrix interference in fish samples. Homogenised fish samples were extracted with acetonitrile, magnesium sulphate anhydrous and sodium chloride. The cleanup sorbents were separately applied to the supernatant during the DSPE procedure; the mixtures were shaken and centrifuged, and the supernatant was dried. The extracts were reconstituted with acetonitrile/water and quantified by liquid chromatography tandem mass spectrometry with electrospray ionisation in the positive mode with two product ions that were monitored by selected reaction monitoring. The performance of each cleanup sorbent was observed for its accuracy and precision in a spiked blank sample at a concentration of 5 μg kg−1. The combination of the cleanup sorbents PSA and C18 was found to be the most effective in the cleanup of the fish samples. In the validation tests, the detection limit was in the range of 0.3 μg kg−1 to 0.4 μg kg−1, and the quantitation limit for all avermectins was 1 μg kg−1 in the linearity range of 1–15 μg kg−1. The recoveries of avermectins were 91.9–102.5%, with a relative standard deviation lower than 19%
An analytical approach on parametric estimation of cure fraction based on weibull distribution using interval censored data.
In this article, we consider the Bounded Cumulative Hazard (BCH) model that is more appropriate than mixture cure model in case of cancer clinical trials when the population of interest contains long-term survivors or cured. We propose this cure rate model based on the Weibull
distribution with interval censored data. Maximum likelihood estimation (MLE) method is proposed to estimate the parameters within the framework of expectation-maximization (EM) algorithm, Newton Raphson method also employed. The analysis showed that the cure fraction cannot be obtained analytically, but may be obtained from the numerical solution of the estimated equations. A simulation
study is also provided for assessing the efficiency of the proposed estimation procedure
Turnbull versus Kaplan-Meier estimators of cure rate estimation using interval censored data
This study deals with the analysis of the cure rate estimation based on the Bounded Cumulative Hazard (BCH) model using interval censored data, given that the exact distribution of the data set is unknown. Thus, the non-parametric estimation methods are employed by means of the EM algorithm. The Turnbull and Kaplan Meier estimators were proposed to estimate the survival function, even though the Kaplan Meier estimator faces some restrictions in term of interval survival data. A comparison of the cure rate estimation based on the two estimators was done through a simulation study
