Investigating Forms of Community Participation in Stunting Prevention: The Case of Balubur Limbangan District, Indonesia

/in /by

This study examines the forms of community participation in preventing stunting in Balubur Limbangan District, Garut Regency, Indonesia, which is one of the areas with high stunting cases. In 2023, stunting cases in this district increased by 34.3%, with the four highest villages being Ciwangi, Pangeureunan, Neglasari, and Surabaya. The research method uses a qualitative approach to describe community participation in preventing stunting. The analysis’s results reveal that Balubur Limbangan’s community only participates through labor, neglecting other forms of participation like thoughts, group discussions, expertise, goods, and money. The causes include lack of awareness and knowledge about stunting, as well as cultural factors. Recommendations include increasing education about stunting through comprehensive socialization and training, as well as intensive awareness campaigns. In addition, it is necessary to increase supervision and evaluation of Integrated Service Post (Posyandu) activities to ensure their effectiveness. We highly recommend collaboration and cooperation between various parties, including Community Health Center (Puskesmas), village governments, and community organizations, to strengthen and increase the effectiveness of stunting prevention and reduction programs.

/in /by

The study assessed class teachers’ familiarity with the official language of instruction in selected urban government primary schools in Solwezi District of Zambia. The objectives of the study were to determine class teachers’ familiarity with the official language of instruction; establish the effects of teachers’ familiarity with the official language of instruction on literacy achievement among urban Grade 3 learners; and ascertain the language instructional strategies teachers who were non-speakers of the language of instruction used to teach in class. The study was guided by The Mother Tongue Instruction Theory, and employed a mixed methods design. Data were collected through interview, lesson observation and fluency test. The study established that teachers who were non-speakers were unfamiliar with the language of classroom instruction, kiikaonde. The fluency test results showed that the teachers’ oral fluency, reading fluency, vocabulary, comprehension, linguistic performance and articulation was generally poor. Interview and observation results showed that the teachers’ unfamiliarity with the official language of instruction impended teaching, learning and learners’ understanding in those classrooms. For instance, the learners misunderstood the concepts, it was time consuming, teachers could not deliver lessons very well because of language barrier and learners did not get the best from the teachers resulting in under performance among teachers and learners. The study also established that the unfamiliar teachers with the language of instruction used variety coping language strategies in the classrooms such as translation, code-switch, group work, individual work and question and answer. The study recommends teachers should be capacity built in familiar language through training in colleges and CPD in schools. The teachers who were unfamiliar with the official familiar language of classroom instruction should not be allocated to teach lower primary classes before they learn the familiar language of instruction by MOE authorities; and the use of variety coping strategies should be encouraged.

Study of the Biodemographic Parameters of Two Genetically Distinct Strains of Callosobruchus maculatus from Two agroecological Zones of Senegal

/in /by

During this study, we determined different biological parameters of Callosobruchus maculatus populations from two agro-ecological zones of Senegal (the ZSP and the ZVFS). To do this, strains of C. maculatus were collected in two localities, each representing an agro-ecological zone. The analysis of the results obtained shows that fecundity is greater for the strain coming from the silvopastoral zone (55.60 ± 19.144 eggs per female) than for that coming from the Senegal River valley zone (45 ± 18.577 eggs per female.). Furthermore, the evolution of egg laying shows that whatever the strain or population, more than 95% of eggs are laid during the first four days of the infestation with a peak on the second. In addition, the strains are characterized by an egg fertility rate exceeding 65% with a larval survival rate of over 75% and the Fouta strain has the highest rates.  However, the emergence rate of the strain from the silvopastoral zone is lower at 49%. The longevity of adults in the Senegal River valley zone is significantly longer (11.035 ± 1.527 days) than that of adults in the silvopastoral zone. The sex ratio is in favor of males for both populations.  The total development time and the oviposition-emergence time are relatively the same in the two strains with an average of 31 days and 21 days respectively.
