Abstract

This research was triggered by the phenomenon of an increase in people adopting a healthy lifestyle during the COVID-19 pandemic. People who adopt a healthy lifestyle are assumed to consume healthy food such as gluten-free food. Meanwhile, as people grow older and their income improves, the desire to consume gluten-free food also increases. This research aims to analyze healthy behavior, age, and income on the desire to consume gluten-free foods that Logit Model constructed. Gluten-free foods can be defined as foods that do not contain gluten substances such as wheat, and they can be classified as healthy food because people who consume this food can avoid some diseases. The study determined Logit Model and used quantitative methods and convenience sampling based on the SPSS application. From 10 to 12 October 2021, research collected 193 respondents, mainly from the Jabodetabek area. Using Wald Test, the study formed a Logit Model for this relationship. In conclusion, healthy living behavior, age, and income partially and simultaneously influence gluten-free food consumption. By observing this study, entrepreneurs in the food sector are expected to produce gluten-free food.

Abstract

Coffee shops are today's businesses with good and competitive prospects in providing customer satisfaction and building customer loyalty. This study aims to analyze the relationship between service quality and product quality on customer satisfaction and loyalty, the relationship between customer satisfaction and customer loyalty, and the relationship between product and service quality and customer loyalty mediated by customer satisfaction. The study was conducted using quantitative methods, sampling a questionnaire to 100 customers of Coffee Shop. The study was conducted in August 2021. Meanwhile, to analyze the relationship between variables, using partial least squares (PLS). Based on the study results, it can be concluded that service quality directly affects customers, especially customer satisfaction. Product quality also affects customer satisfaction and loyalty and vice versa. However, service quality did not directly affect customer loyalty. Meanwhile, mediation through customer satisfaction and product quality indirectly affects customer loyalty.

Abstract

Aphis craccivora is one of the important pests on yard long bean. It causes direct damage and also has an indirect effect as insect vector of the Bean common mosaic virus (BCMV). The research was done to test the effectiveness of chitosan in suppressing aphid population growth, feeding preference and its ability in transmiting BCMV. Chitosan with concentration ranging of 0.1–1.0% were applied on leaves using spraying method at 1 day before BCMV transmission. BCMV was transmitted by using 3 individuals of viruliferous aphids on each plant. Results show that chitosan treatments on leaves or plants significantly suppressed the population and feeding preferences of A. craccivora. Further, treated plants showed lower disease incidence, severity and BCMV titre significantly compared with untreated control plants. The positive effects of chitosan in suppressing population growth as feeding preferences and BCMV transmission might be due to the anti-feedant effect of chitosan on A. craccivora. Based on the result, chitosan at concentration 0.9% is the most effective concentration in suppressing BCMV and its vector A. craccivora.

Abstract

Papaya mealybug, Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae), is an invasive pest that was detected for the first time in Indonesia in 2008. One of the common natural enemies is the predatory beetle Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae). The research was conducted with the objectives to determine the biology, life table parameters, and predation of C. montrouzieri on P. marginatus. Observation of biological and life table parameters and predation was conducted by introducing the predators into Petri dishes containing mealybugs. Eggs of C. montrouzieri hatched in 4.35 days. Mean developmental periods for 1st, 2nd, 3rd, and 4th instar larvae were 4.23; 4.21; 5.84; 5.93 days, respectively. The mean pre-pupal and pupal periods were 1.95 and 7.55 days, respectively. The longevity of male adults was 51.34 days, while that of females was 83.39 days. The number of eggs laid by a single female averaged 198.49. The net reproductive rate (Ro) was 117.11 individu/female/generation, intrinsic rate of increase (rm) was 0.073 individu/female/day, mean generation time (T) was 64.776 days, doubling time (Dt) was 9.426 days, and finite rate of increase (λ) was 1.076 per day.  The 4th instar larvae of C. montrouzieri was the most voracious with numbers of P. marginatus eggs, 1st, 2nd, 3rd instar nymphs or adults consumed were 188.0; 53.4; 44.0; 26.8; or 15.6; respectively. Manly's preference index suggested that larvae, as well as adults of C. montrouzieri, preferred eggs and 1st instar nymphs of P. marginatus over other mealybug stages. Our study indicates the high potential of C. montrouzieri in the biological control of P. marginatus.

Abstract

Mass rearing techniques for the production of Spodoptera frugiperda larvae in large quantities as research materials is important to be developed. Baby corn has the potential to be observed as alternative feed for mass rearing of fall armyworms. However, the biology and life table of S. frugiperda feeding on baby corn has not been studied. This research aims to study the morphology, biology, and life table of S. frugiperda fed on baby corn. Larvae of F1 fall armyworm were reared singly and fed with baby corn, after pupation it was moved to containers. Thirty pairs of adults were reared in a cage filled maize plant. Observations conducted daily from the eggs until the adult died. Results showed variations in the color and size of the eggs, larvae, pupae, and adults. Developmental periods of eggs, larvae, and pre-pupae were 2.47, 14.96, and 1.83l days. Pupal period was 9.75 days (male) and 8.81 days (female). The life cycle were 37.69 days (male), and 37.7 days (female). Duration of pre-oviposition, oviposition, post-oviposition were 1.60, 7.90, and 2.26 days. Adult longevity was 11.34 days (male) and 11.76 days (female). The average number of eggs laid was 1.365,86/female with a hatch rate of 94,68%. Survival curve of S. frugiperda was type I, with GRR  of 1.442,49 individuals/generations, and  the Ro was 1.342,77 individuals/females/generation. Ther was 0.23 individual/female/day, the T  was 31.23 days, and the DT was 3.01 days. This result showed that baby corn can be an alternative feed for mass rearing of S. frugiperda.

Abstract

The apparel industry in Indonesia is a labor-intensive industry capable of absorbing a very large workforce. According to BPS (Central Statistics Agency) data in 2020, proportion of the workforce in the manufacturing industry sector, the industry accounts for 1.81% of the workforce out of a total of 13.61% of the total workforce or is in second place after the food industry. With a very large number of workers, it is only fitting that K3L be a common concern. Method for this research is using of literature review method, using secondary data sources originating from national journals related to the K3L application in the apparel industry. The result of sorting several journals obtained journals as many as 10 research journals. Purpose of this research is to analyze the implementation of K3L in the apparel industry so that a broader picture of this implementation will be obtained. Based on the result of research, the conclusion can be gain are: 1) the number of research that related with occupational health and the environment in the apparel industry in Indonesia is still limited. Meanwhile, there are many journals related to work safety, 2) related with the application of work safety in the apparel industry in Indonesia, showing good implementation results, 3) in terms of work accident risk, it is more related to risk identification and risk analysis, while evaluation and risk control are still lacking.
