Abstract

Abstrak – Obesitas merupakan salah satu masalah kesehatan masyarakat yang dapat meningkatkan prevalensi kesehatan yang buruk dimasa depan. Data riskesdas 2018 menunjukan bahwa prevalensi obesitas meningkat dari tahun 2007 sampai 2018. Tujuan penelitian ini untuk mengetahui durasi tidur aktivitas fisik, asupan energi dan status obesitas SD Islam Al Azhar 1. Desain penelitian Penelitian ini merupakan penelitian kuantitatif observasional yang bersifat deskriptif dengan pendekatan cross sectional. Jumlah anak yang terlibat sampai akhir penelitian sebanyak 50 anak. Hasil penelitian menunjukan 60% anak memiliki status gizi gemuk/obesitas. Aktivitas fisik anak dengan kategori rendah sebanyak 55% pada anak non obesitas dan 47% pada anak obesitas. Sebagian besar anak memiliki durasi tidur yang baik yaitu kelompok non obesitas (95%) dan obesitas (83%). Tingkat kecukupan energi dengan kategori lebih pada kelompok non obesitas sebesar 35%, sedangkan kelompok obesitas sebesar 37%. Asupan energi yang berlebih beresiko terhadap status gizi anak, walaupun durasi tidur anak sudah baik, namun sebagian besar anak masih memiliki aktivitas yang rendah. Diharapkan pihak sekolah dapat meningkatkan aktivitas fisik melalui ekstrakurikuler yang menunjang aktivitas fisik, selain itu anak perlu mengurangi kebiasaan yang menghambat aktivitas anak seperti menonton TV dan bermain gadget dalam waktu lama.Abstract – Obesity is one of the public health problems that can increase the prevalence of poor health in the future.

Abstract

PLN Unit Induk Pembangunan Kalimantan Bagian Timur (PLN UIP Kalbagtim) is a company that is responsible for electricity needs in the East Kalimantan region. PLN UIP Kalbagtim covers three types of projects. There are power projects, substation projects, and transmission projects. However, many of these projects experienced delays in their Commercial Operation Date (COD). PLN UIP Kalbagtim only measures the risk level generally and does not measure the root causes of the possible occurrence of this risk. Based on these problems, a study was conducted to identify the projects that experienced delays the most using the Pareto diagram, then analyzed the factors and root causes of the delay using a fish-bone diagram, then using the Analytical Hierarchy Process method, data processing was done to obtain the probability value of each root event. Furthermore, using the Fault Tree Analysis method, the probability value of delay is calculated until the smallest value is found. From the research that has been done, it can be concluded that the transmission project in the form of SUTT is the project that most often experiences delays due to machine, man, material, method, and money factors. The factor that must be set as the priority or focus of the company is the money factor and the root of the incident in it will also be automatically deleted so that the possibility of delays is reduced from 52.71% to 25.28%. Keywords - Analytical Hierarchy Process, Fault Tree Analysis, Pareto Chart, Fish-bone Diagram

Abstract

Abstrak - HIV (Human Immunodeficiency Virus) masih menjadi masalah kesehatan yang belum terselesaikan hingga saat ini. Orang dengan HIV/AIDS (ODHA) memiliki peluang yang besar untuk mengalami kekurangan asupan gizi karena hilangnya nafsu makan, gangguan metabolisme dan penyerapan makanan. Kualitas diet yang baik erat kaitannya dengan penurunan risiko kematian pada ODHA. Tujuan penelitian ini untuk mengetahui kualitas diet pada ibu dengan HIV/AIDS. Penelitian ini merupakan penelitian kuantitatif dengan desain potong lintang (cross sectional). Penelitian dilakukan dari bulan Januari hingga Oktober 2019, data dikumpulkan terdiri dari karakteristik ibu, riwayat pengobatan serta data konsumsi makanan. Kualitas diet ditentukan diawali dengan tahapan pengelompokan pangan kemudian dikonversi ke dalam bentuk skor dengan menggunakan instrument Indeks Gizi Seimbang (IGS) 3-60. Hasil penelitian pada 14 responden ibu dengan HIV/AIDS menunjukkan bahwa lebih dari setengah jumlah responden berstatus gizi Normal 57,1%, Gemuk 35,7%, dan paling sedikit responden dengan status gizi Kurus 7,2 %. Indeks Kualitas Diet ibu dengan HIV/AIDS hanya memenuhi 47% dari total skor maksimal IGS 3-60, skor terkecil ditunjukkan oleh indikator kecukupan sayur-sayuran dan konsumsi susu yang berarti kurang. Responden dalam penelitian ini hanya mengonsumsi sayur kurang dari 1 porsi dalam satu hari sedangkan anjuran untuk mengonsumsi sayur adalah minimal 5 porsi/hari. Saran penelitian ini agar responden  menjaga kosumsi sayur-sayuran dan harus secara rutin mengontrol berat badan. Selain itu dibutuhkan penelitian lanjutan terkait Kualitas Diet pada ibu dengan HIV/AIDS dengan responden yang lebih banyak dan beragam profesi, tidak dalam lingkup IPPI saja.Abstract - HIV (Human Immunodeficiency Virus) is still an unsolved health problem until now. People with HIV/AIDS (PLWHA) have a great opportunity to experience low nutritional intake due to loss of appetite, metabolic, and food absorption disorders. A good quality diet is closely related to a reduced risk of death of people with HIV. The purpose of this study was to determine the diet quality of mothers with HIV / AIDS. This research was a quantitative study with a cross-sectional design. The study was conducted from January to October 2019, data collected included respondent characteristics, drug/treatment history, and food consumption data. Food consumption data were processed with food grouping stages and then converted to a score using the Balanced Nutrition Index (IGS) 3-60. The study results from 14 mothers with HIV/AIDS showed that more than half of them had normal nutritional status 57.1%, 35.7% of them were overweight, and 7.2% of them were thin. The diet quality index (DQI) of mothers with HIV/AIDS only met 47% of the maximum total score of IGS 3-60, the smallest score was indicated by the adequacy indicator of vegetables and milk consumption, respondents in this study only consumed vegetables less than 1 serving per day. The suggestion of this research was for respondents to maintain the consumption of vegetables and must routinely control their body weight, further research is also needed on the Diet Quality Index in mothers with HIV / AIDS with a higher respondent number.Keyword - HIV/AIDS, DQI, Nutritional Status

Abstract

Plant Root Growth Promoting Bacteria or PGPR are bacteria that colonize plant rooting areas or the rhizosphere to increase the quality or quantity of plant growth. PGPR can provide dissolved phosphate for plants to be absorbed by the plant root system since 95-99% of phosphate in nature is present in insoluble form. Soil samples from different irrigation systems from Akar-akar village were isolated through serial dilution techniques and grown on NA media shown that the higher the dilution, the fewer colonies that grew on the media. Macroscopic and microscopic observations were made to see the criteria for bacteria, shown that the bacteria in the three soil samples were gram negative and was known that bacillus and cocobacillus bacteria present in the three soil samples. Coccus bacteria was found in soil without irrigation and drip-surface irrigated soil, while streptococcus bacteria was found in drip-surface and drip-subsurface irrigated soil. As many as 22 bacterial isolates were isolated and grown on Pikovskaya media, only one bacterial colony was phosphate solvent through a clear zone that grew around the bacterial colony. The bacterial colony has a phosphate dissolving index (IPF) of 250, the ratio between colony diameter and clear zone diameter was 1: 1.5.Keywords – PGPR, Drip-surface irrigated soil, Drip-subsurface irrigated soil

Abstract

In Indonesia, the prevalence of helminthiasis is still high, especially in children. The frequency is 60-70% in populations at risk. The lack of use of family latrines causes soil contamination with feces around the yard. There are still few articles that review the morphology of worms that cause infectious diseases in Indonesia. Whereas knowledge of morphology is important to understand the life cycle of worms that play a role in disease transmission in humans and mammals. This article aims to discuss the latest findings regarding the morphology of worms that cause infectious diseases in humans. It can be concluded that at the adult stage, worms can be sexed. Usually, the female type has a relatively larger size than the male. On the head (anterior) there are 3 lips that have sensor papillae, one on the mediodorsal and 2 on the ventrolateral. Between the 3 lips there is a bucal cavity which is triangular in shape and functions as a mouth.Keywords - Morphology, Helminth, Infectious disease
