Abstract

Effective face-to-face tutorial will be affected by some factors such as number of participants, the scattered locations, the lack of competent tutors, and the poor management system. Specifically, this problem was caused by (i) tutors who teach too many subjects, (ii) the mismanaged scheduling system that a tutor teaches in different classes at the same time. Through decision support system, scheduling is expected to become more effective and efficient. Constraint programming was used as a method to solve problems through mathematical calculation based on prerequisites and limitation. However, the lack of competent tutors remain a major obstacle in running face-to-face tutorial. Efektivitas pelaksanan tutorial tatap muka menjadi berkurang, antara lain akibat besarnya jumlah peserta , tersebarnya lokasi tutorial tatap muka, tidak kompetennya tutor, dan lemahnya sistem pembuatan jadwal tutorial. Masalah ketidakefektifan ini disebabkan oleh (i) adanya tutor yang yang mengajar untuk beberapa matakuliah, (ii) sistem penjadwalan yang tidak baik sehingga terdapat tutor yang mengajar pada beberapa kelas pada waktu yang sama. Dengan demikian penjadwalan tutorial menjadi masalah yang penting dalam pelaksanaan tutorial tatap muka. Melalui Sistem Pendukung Keputusan, penjadwalan tutorial diharapkan dapat menjadi lebih efektif dan efisien. Untuk mencari solusi terhadap persoalan ini, digunakan Constraint programming. Cara ini didasarkan pada perhitungan matematika dengan memperhitungkan batasan-batasan yang ada. Namun demikian, kualitas tutor tetap merupakan kunci permasalahan. Kurangnya tutor yang berkompeten akan mempengaruhi efektivitas tutorial tatap muka.

Abstract

The decrease in the prevalence of nutrition recorded in the Indonesian Nutrition Status Survey (SSGI) in 2021-2022 by 2.8% (Ministry of Health of Indonesia, 2023) indicates an improvement in the nutritional status of the community. One of the factors that influence nutritional status is the consumption pattern of nutritious vegetables. Moringa (Moringa Oleifera), has an important role in improving nutrition due to its high nutritional content. However, the utilisation of Moringa leaves is still limited due to the community's lack of understanding about the benefits and consumption of Moringa leaves. This study aims to identify the factors that influence people's consumption of moringa leaves with a case study in Surabaya City. A total of 70 respondents who had consumed moringa were selected through a two-stage cluster sampling method. Analyses were conducted to evaluate the influence of consumption goal variables, availability, price, and information sources on moringa consumption patterns. The results show that the source of information is a factor that has a significant effect on consumption patterns. These findings indicate the importance of disseminating appropriate information to increase the utilization of moringa in the moringa vegetable diet for people in Surabaya.
