Abstract

The purpose of this research was to determine the society's understanding of disaster mitigation or preventing the likelihood of landslides, and efforts have been made public as well as solutions regarding prevention or reduction of the occurrence of landslides. This research was conducted in the Toobaun village of West Amarasi, Kupang district. The sampling technique was proportional random sampling. Sampling from entire population was taken as 100 respondents using descriptive analysis. The results showed that: 1) The level of public understanding about vulnerable to landslides and how to cope with and mitigate that are in the low category, where people suffered a lot of losses and damages caused by landslides, 2) Efforts have been made public categorized as high, and solutions in case of landslide still categorized low, people's knowledge and understanding of disaster mitigation less than the maximum so that the public is less aware of the potential damage caused by landslides. Keywords: The public's understanding, mitigation, landslides, Toobaun

Abstract

Defisiensi seng (Zn) pada tanah alkalin-kalkareus lahan kering Nusa Tenggara Timur (NTT) mengancam kualitas gizi jagung dan risiko stunting, namun kajian pedokimia lokalnya masih terbatas. Penelitian ini menganalisis dinamika ketersediaan Zn pada tanah alakalin NTT dan mengkuantifikasi akumulasinya dalam biji jagung lokal. Survei (Kupang, TTS, TTU) dengan 36 sampel tanah dan biji jagung dianalisis menggunakan korelasi Spearman, ANOVA, dan regresi berganda stepwise. pH berkorelasi negatif dengan Zn-DTPA (r=-0,65; p<0,01), sementara bahan organik berkorelasi positif nyata (r=0,71; p<0,01); setiap kenaikan pH menurunkan Zn tersedia sebesar 0,78 mg/kg. Model regresi tiga variabel (pH, bahan organik, KTK) menjelaskan 79% variasi Zn tersedia. Kandungan Zn biji berkisar 9,8-22,3 mg/kg, seluruhnya di bawah ambang WHO (20-40 mg/kg). Manajemen pH dan peningkatan bahan organik merupakan kunci optimasi Zn di lahan kering alkalin NTT.Kata Kunci: akumulasi Zn jagung, bahan organik tanah, dinamika seng, lahan kering, pH alkalin, Zn-DTPA
