Abstract

Prupuh village is a village in the district Panceng by having a hamlet that Hamlet Prohibition. 2000more residents in the village Prupuh with 575 heads of household, and 400 homes were built. In generallivelihoods of the majority of the villagers are farmers Prupuh. In the rainy season corn is one of the cropsgrown by the residents both in the fields and in the yard. Corn Transformation Machine addressed to thevillagers of Prupuh that planting corn with manual harvesting. People have become less productive becauseof the time needed to separate the corn from bongkolnya very long. From the experimental results usingCorn Transformation Machine tool time needed to separate the corn seed from bongkolnya ie 30 secondsper 1 piece of corn, while if using a hand (manual) takes 5 minutes per 1 piece of corn. The tool can savetime for 4.5 minutes and simultaneously increase productivity the amount of corn kernels are separatedfrom bongkol.

Abstract

ABSTRACTA green house experiment were conducted to study the application of “compost plus” on the growth of Orthosiphon aristatus. The experiment was designed in Complete Randomized Design with factorial and five replicates. The first factors were fertilizer application (compost plus, compost, and control). The second factors were 3 kinds of soil (i.e. soil from Cibinong, Ciomas, and Sukabumi). The result showed that compost plus application increased 113.90 gram/pot of dry weight of Orthosispon aristatus leaves compared with compost application and control in 3 kinds of soil.Key words : Compost plus (compost + microbes), Orthosispon aristatus

Abstract

Background: Hypertension or increased blood pressure is often referred as the silent killer because it usually does not show significant signs and symptoms. Thus, almost all patients do not realize if they suffer from hypertension. The Basic Health Research (Riskesdas) 2007 reported that the prevalence of hypertension in the population aged over 18 years old in Indonesia was 31.7%. Because of the increasing prevalence of hypertension in adolescence, it is necessary to take precautions. This study aimed to examine the relationship between demographic factors and body mass index with the prevention of hyper­tension in adolescentsSubjects and Method: This was a cross sec­tional study conducted at Muhammadiyah 1 Senior high school, Yogyakarta, from May 2017 to February 2018. A sample of 80 students was selected for this study. The dependent variables were prevention behavior. The independent variables were age, sex, body mass index (BMI), and residence. The data were collected by questionnaire and analyzed by Chi square.Results: 48 (60%) students had good hyper­tension prevention behavior. Female (OR= 3.00; p= 0.030), urban residence (OR= 2.78; p= 0.040), and normal body weight (OR= 4.30; p= 0.001) increased behavior of hypertension prevention, and they were statistically signi­ficant. Older age (OR= 1.59; p= 0.220) incre­ased behavior of hypertension preven­tion, but it was statistically non-significant.Conclusion: Female, urban residence, normal body weight, and older age increase behavior of hypertension prevention.Keywords: hypertension prevention behavior, demographic factorsCorrespondence: Ratna Indriawati.

Abstract

Perlindungan terhadap keamanan jaringan merupakan hal yang sangat penting untuk dilakukan. Mengingat kemudahan dalam mengakses jaringan memungkinkan adanya gangguan dari pihak yang ingin menyerang, merusak, bahkan mengambil data penting. Honeypot memang tidak menyelesaikan masalah pada keamanan jaringan, namun honeypot membuat penelitian tentang serangan menjadi lebih sederhana dengan konsep yang mudah untuk dimengerti dan dimplementasikan. Penelitian ini menerapkan beberapa honeypot menggunakan Raspberry pi dan ELK stack untuk monitoring hasil yang didapatkan oleh honeypot. Tujuan dari penelitian ini untuk merancang sistem yang mampu mendeteksi serangan pada jaringan menggunakan honeypot. Raspberry pi digunakan sebagai sensor honeypot untuk pemantauan ancaman keamanan terbukti hemat biaya dan efektif menggantikan komputer desktop. ELK stack memudahkan pemusatan data dari berbagai sumber dan membuat analisis log yang awalnya rumit untuk dianalisis menjadi lebih menarik.

Abstract

Coal and Mineral mining activities have a high risk of ecosystem changesthat affect the environment, let alone the mining is carried out openly. In order torestore the condition of the land in such a way that it can function and to be effectivein line with its allocation, the ex-mining area must be restored. Reclamation andpost-mining activities shall be conducted by every holder of Mining Business Permit(IUP) Exploration and IUP Production. Holders of IUP Exploration must firstlyprepare reclamation and post-mining plans in the permit process. The implementationof reclamation and post-mining activities by holders of IUP Production Operationand Special Mining Business Permit (IUPK) Production Operation must complywith the principles of : (1)protection and management of mining environment; (2)working safety and health; and (3) mineral and coal conservation. To determinethe success of the land that has been reclaimed and the post-mining activities havebeen complied, if an evaluation has been made by the competent officials and it isstated that the reclamation and post-mining activitie shave been performed well inaccordance with prevailing regulations.
