Prevalensi dan determinan kejadian gizi kurang pada balita

Abstract: Status gizi seseorang dipengaruhi oleh konsumsi pangan keluarga Keluarga nelayan sangat bergantung pada usaha perikanan Desa Bajomulyo merupakan salah satu daerah nelayan yang masih banyak masalah kasus gizi kurang Tujuan penelitian ini adalah untuk mengetahui hubungan antara tingkat konsumsi energi dan protein, penyakit infeksi, tingkat pengetahuan ibu, tingkat pendidikan ibu, tingkat pendapatan, pola asuh, jumlah anggota keluarga dan kontribusi protein ikan dengan status gizi balita pada keluarga nelayan Jenis penelitiannya adalah survei dengan desain belah lintang Populasi seluruh balita usia 1-5 tahun dari keluarga nelayan sejumlah 50 balita Sampel diambil secara total dengan Ibu balita sebagai responden Analisis hasil penelitian dengan uji chi square Hasil penelitian menunjukan bahwa faktor yang berhubungan dengan status gizi adalah konsumsi energi (p = 0001), konsumsi protein (p = 0001), penyakit infeksi (p = 0001), tingkat pengetahuan (p = 0002), tingkat pendidikan (p = 0001), tingkat pendapatan (p = 0002)  Abstract A person’s nutritional status is influenced by family food consumption Fishermen famili depend on fisheries Bajomulyo Village is one of the fishermen who are still numerous cases of malnutrition The purpose of this study was to determine the relationship between the level of energy consumption, the intake of protein, infectious diseases, the level of knowledge of mothers, maternal education level, income level, parenting, family size and contribution of fish proteins with nutritional status of children in fisherman families This survey is a research with cross sectional design Entire population of children aged 1-5 years of fisherman families for 50 toddlers Samples were taken in total, with toddler mothers as respondents Analysis of the results of research is done by chi square test Results show that factors associated with nutritional status is the energy consumption (p = 0001), consumption of protein (p = 0001), infectious diseases (p = 0001), level of knowledge (p = 0002), educational level (p = 0001) and income level (p = 0002) Keywords : Malnutrition; The determinant factor; Toddlers; Families of fishermen

Tipe Kesalahan Mahasiswa dalam Menyelesaikan Soal-Soal Geometri Analitik Berdasar Newman’s Error Analysis (NEA)

Abstract: Kemampuan mahasiswa dalam menyelesaikan soal-soal matematika langsung atau tidak langsung dipengaruhi oleh pola penyelesaian soal pada saat mahasiswa duduk di bangku sekolah. Hasil pengamatan menujukkan bahwa masih terdapat mahasiswa yang tidak malakukan tindakan apapun terhadap soal pembuktian, meskipun hanya pada tahapan understand the problem. NEA merupakan kerangka kerja dengan prosedur diagnostik sederhana, yang meliputi (1) decoding , (2) c omprehension , (3) transformation , (4) process skill , dan (5) encoding . Metode diagnostik yang dikembangkan Newman ini digunakan untuk mengidentifikasi kategori kesalahan terhadap jawaban dari sebuah tes uraian. Sehingga bagaimana deskripsi jenis kesalahan mahasiswa dalam menyelesaikan soal-soal pembuktian pada mata kuliah Geometri Analitik berdasarkan Newman’s Error Analysis (NEA), dan apa saja penyebab kesalahan mahasiswa dalam menyelesaikan soal-soal pembuktian, khususnya pada mata kuliah Geometri Analitik, menarik untuk dibahas dalam tulisan ini.

Understanding of Petobo liquefaction flowslide by 2018.09.28 Palu-Donggala Indonesia earthquake based on site reconnaissance

Abstract: The Palu-Donggala earthquake struck Palu city of Sulawesi island, Indonesia, on 28 September 2018. A large-scale liquefaction phenomena occurred in some areas which caused massive fatalities and destructions. The most severe liquefaction incident during the earthquake followed by flowslides occurred in Petobo district of the city. The affected area due to Petobo flowslide liquefaction was approximately 1.64 km2. The damages were severe because of densely populated area with estimated more than 3300 houses collapsed and nearly 2000 fatalities. The slide materials transformed into debris and flowed on the low-relief ground of about 2% with a slide distance of more than 800 m. A site reconnaissance of Petobo flowslide was conducted in early 2020, which covered surface observations and documentations before and after the flowslide, interpretations of geological characteristics, summary of witness interviews, analyses of ground displacement and changes in surface elevation and slope due to the flowslide. The results reveal insights as to the failure mechanism of the Petobo flowslide. Based on the observed phenomena on the surface, the Petobo flowslide area could generally be divided into four types of morphology, namely, ground slide (GS), liquefaction spread (LS), liquefaction flow (LF) and debris flood (DF). The GS and LS were considered to be the initiation zones, then the slide materials spread down and formed LF zone. In this area, the soils became wet and muddy as triggered by liquefaction. The liquefied materials then transported into DF zone where densely populated areas in lower elevation of the site were hit.

The Application of Differential Equation of Verhulst Population Model on Estimation of Bandar Lampung Population

Abstract: This study is aimed to predict the population of Bandar Lampung up to the year 2025. This approach applies the Verhulst Population Model. The solutions to the model by using mathematical techniques of the differential equation. Results show that the Verhulst population model predicted the population of Bandar Lampung to be 1,147Million in 2025, with used to estimate the population in Bandar Lampung city is .
