HYDROLOGY ANALYSIS FOR THE JOHOR RIVER USING SYNTHETIC UNIT HYDROGRAPH GAMA I

A series of floods occurred in several places in Malaysia during December 2006 – January 2007,including the southern state of Malaysia; Johor Bahru. The rain recorded in the city of JohorBahru was 286 mm. To understand this phenomenon and to investigate the design flood of thisregion, a hydrology analysis procedure was taken into account. The hydrology analysis procedureincludes collecting rainfall data, analyzing rainfall data including areal rainfall and rainfallfrequency, developing synthetic unit hydrograph using SUH GAMA I. It is noticed that the lengthof rainfall data collected, i.e. 60 years, is sufficiently long for analysis. From the hydrologyanalysis done in this study, it can be concluded that the rain fell during 2006-2007 flood eventshad nearly 100 years period of rainfall. And the prediction for 100 years period of flood is 16,962m3/s

HYDRAULIC ANALYSIS OF THE JOHOR RIVER USING HEC-RAS

Kota Tinggi located in the southern state of Malaysia, i.e. Johor Baru, experienced severe floods in December 2006 and January 2007, which was due to prolonged and intense rainfall. Johor River was inadequate to accommodate the water and at the same time the flow unable to escape the swolen river, hence water inundated the town. One of the river characteristics that may contribute in flooding is the meandering shape. Therefore it was proposed to do a hydraulic model that simulated some alternate channels that straightened some parts of the river. The model used one dimensional steady state approach using HEC-RAS software. The simulation result of the existing condition estimated that January 2007 flood event had a return period of 100 years. From the hydraulic model, it can be concluded that the choice of location and the length of the alternate channel had an effect on how much water level reduced

PENGARUH PANDEMI COVID-19 TERHADAP EKSISTENSI BISNIS UMKM DALAM MEMPERTAHANKAN BUSINESS CONTINUITY MANAGEMENT (BCM)

This study aims to analyze the impact of the Covid-19 pandemic on the existence of MSME business in business continuity management (BCM). The research methods used is descriptive qualitative method based on secondary data from  research  result and reference on data and information from journals and online reporting. The result showed that the impact of the Covid-19 pandemic was felt directly by the sustainability of the MSME business in decreasing its productivity. The business sector that wass constrained by its development and even experienced a decline during the Covid-19 pandemic was the transportation, tourism, shopping center, and offline trade business which only focused direct consumer visits. While business activities that can still survive and exist to serve consumers (transformed using an online application platform) are education, retail, staple food

CONCEPT MAP STRATEGY TO ORGANIZE IDEAS IN WRITING EXPOSITION TEXT

The purpose of this research was to find out the effectiveness of concept map to organize ideas in writing exposition text. This research was conducted in one senior high school in Purwokerto in academic year 2018/2019. The population was all the eleventh grade students in that school. Researcher used two classes as control group and experimental group. This research used quasi experimental research which was done in November 2019. The instrument of collecting data was tested. The test was done twice which called pre-test and post-test. The type of the test was writing test. T-test formula was used to analyze the data. Based on the computation, t-test result was 3.535 and the t-table was 1.677 at significant level 0.05 with the degree of freedom 48. It showed that t-result was higher than t-table. Based on the research result, it can be concluded that concept map was effective to organize ideas in writing exposition text

Analisis Dampak Tanggul Terhadap Elevasi Banjir Sungai Nagara Kalimantan Selatan

Nagara River is a river in South Kalimantan province with extensive swamp area which formsseasonal flood plain and protects downstream area from flooding and salt water intrusion. Theplan for land use change from the swamp area to plantation area involves building dyke on thesides of Nagara River. This research aims to analyze the elevation of Nagara River duringflooding when the swamp area is occupied as an extension of flood plain, compared that resultedfrom the scenario when this area is converted into plantation area which needs dyke on the sidesof the river for flood protection. There are two kinds of scenarios, first only one side of the riverwhich will be build dyke, and second both sides of the river will be built dykes. The analysisinvolved rainfall data analysis using daily module rainfall, design discharge analysis usingRational Method and hydraulic analysis using HEC-RAS software with one-dimensional steadyflow. The result shows that using dyke at elevation +11.00 m, the increase of water level is notsignificant while one side of the river is protected by dyke. An increase of 30 cm of water elevationis obtained using scenario of both sides are protected by dykes. The increase of water level maycause flooding in the area located at the upstream and downstream of the plantation area

FAKTOR-FAKTOR YANG MEMPENGARUHI KEJADIAN STUNTING PADA ANAK BALITA

AbstrakStunting adalah salah satu keadaan malnutrisi yang bersifat kronik yang dapat menimbulkan gangguan perkembangan fisik, penurunan kognitif serta penurunan motorik. Stunting pada anak balita merupakan konsekuensi dari beberapa faktor yang sering dikaitkan dengan kemiskinan termasuk gizi, kesehatan, sanitasi dan lingkungan. Tujuan penelitian ini untuk mengetahui faktor-faktor yang mempengaruhi kejadian stunting pada anak balita.Penelitian ini merupakan jenis penelitian observasional analitik dengan desain kasus kontrol. Sampel yang diambil sebanyak 24 balita untuk masing-masing kelompok kasus maupun kontrol dengan teknik simple random sampling. Analisis data menggunakan chi square dengan α=0,05 pada interval kepercayaan 95% dan regresi  logistik  pada interval kepercayaan  95%.Hasil analisis menunjukan bahwa faktor yang mempengaruhi terjadinya stunting di desa Semali Kecamatan Sempor Kabupaten Kebumen adalah riwayat pemberian ASI Eksklusif (OR=3,40; CI=1,03-11,07), Riwayat Penyakit Infeksi (OR=3,54; CI=1,05-11,92), dan Keteraturan Menimbang di posyandu (OR=0,020; CI=1,04-16,19). Namun untuk faktor riwayat BBLR, pola asuh makan, dan pendapatan keluarga tidak mempengaruhi terjadinya stunting.Terdapat hubungan antara riwayat pemberian ASI Eksklusif, Riwayat Penyakit Infeksi, dan Keteraturan Menimbang di posyandu terhadap kejadian stunting pada balita.Keywords: Stunting, Anak Balita, ASI Eksklusif  AbstractStunting is chronic malnutrition that can cause physical Developmental Problems, reduced cognitive and motor function. Stunting among children under 5 years of age is the consequence of several factors that are often associated with poverty, including nutrition, health, sanitation and environment. The aim of this research is to determine the factors affecting the prevalence of stunting in children under five years of age.This research is analytical observational study with A case-control design. Samples were 24 toddlers for each of case and control group using Simple random sampling. Data analysis was conducted by chi-square test with α = 0.05 at the 95% confidence interval and the logistic regression at the 95% confidence interval.The result of the analysis shows that the factors influencing the occurrence of stunting in Semali Village, Sempor District, Kebumen Regency is the record of exclusive breastfeeding. (OR = 3.40; CI = 1.03-11.07), the record of infectious diseases (OR = 3.54; CI = 1.05-11.92), and the regularity measuring weight of children at Posyandu (OR = 0.020; CI = 1.04-16.19). However, the factors of low birth weight history, dietary care, and family income do not influence the occurrence of stunting.There is a relationship among  history of exclusive breastfeeding, history of infectious diseases, and regularity measuring weight of children at Posyandu to the incidence of stunting in children under five years of age.Keywords: stunting, toddler, exclusive breastfeeding
