Pengambilan sampel menggunakan metode simple random sampling. Instrument yang digunakan adalah timbangan berat badan dan tinggi badan, bangku harvard, metronome, stopwatch dan lembar data produktivitas. Analisis data menggunakan uji Chi-Square dengan α = 0,05. Dan didapatkan hasil bahwa ada hubungan antara status gizi (p=0,005), tingkat kebugaran jasmani (p=0,001) dengan produktivitas kerja. The purpose of this research to determine the relationship between nutritional status and level of physical fitness by working on labor productivity. This research was explanatory research with cross sectional approach. Population was a 73 employees. And sample was 45 employees. Instrument was a weight scales and height, harvard bench, metronome, stopwatch and productivity data sheet. Was processed, using the Chi-Square statistic with α = 0.05. The results was a relationship between nutritional status (p = 0.005), level of physical fitness (p = 0.001) with labor productivity. This research will expect workers to consume foods that contain balanced nutrition and exercise to improve physical fitness

Diversity and abundance of medicinal plants in Penggaron tourism forest of Central Java, Indonesia

Nowadays, the need for medicinal plants as raw materials of traditional medicine is increasing. This study aims to determine the plant species that potential as medicine and its abundance in Penggaron Tourism Forest. Study sites were in the mixed forests and pine forests of Penggaron tourism forest. Vegetation sampling was carried out using a plot method with a size of 10 x 10 m for tree strata, 5 x 5 m for shrub strata and 1 x 1 m for grass or herbaceous strata. Each species of medicinal plant found was identified up to species level and determined their benefit. The medicinal plants found in the study site was 24 species, consisting of 15 families. The most commonly found plant species i.e., the Familia Asteraceae (Chromolaena odorata, Crassocephalum crepidiodes, and Elephantopus scaber), Malvaceae (Hibiscus tiliaceus, Sida rhombifolia, and Urena lobata) and Zingiberaceae (Alpinia galanga, Zingiber officinale, and Zingiber montanum). The habitus of found medicinal plants were 25% tree, 25% shrubs and 50% herbs/grasses. Medicinal plants in the Penggaron forest have not been widely used by people around the forest

Optimization of Device Installations in the Home Solar Power Generation System

One of the main challenges in building a Solar Power Generation System at home or a Home Solar Power Plant (Home SPP) is choosing component specifications according to price. The main components of Home SPP are photovoltaics (PV) panels, inverters, and wiring systems. Given the strict price constraints, the selection of parts available on the commercial market is generally of low quality. However, low-quality components can still provide a significant advantage by optimizing the plant design. This research proves that the proper configuration can reduce electricity bills by 52.2%. This configuration does by choosing a Grid Tie Inverter (GTI) with a high working voltage and a 12 Volt PV configured in a parallel series circuit to work at 24 Volts. In addition, the 12 Volt PV panels configured in series to 24 Volts are proven to increase the conversion efficiency

Efektivitas Pemberian Rebusan Kunyit Asam terhadap Penurunan Dismenorea

The aim of this research was to determine the effectiveness of tumeric and tamarind to relieve dysmenorrhoea. The method was quasy experiment by giving tumeric and tamarind stew to the experimental group. The research was conducted on SMAN 9 Pekanbaru, toward 30 respondent which devided into two group. The first group was experimental group and the second group was control group. The sampling used purposive sampling technique, the measurement was a numeric rating scale to measure the intensity of pain. The analysis were univarite and bivariate analysis by using t-dependent sample test and mann whitney. The result showed there was a significant reduction of the intensity of pain to the experimental group after the group had taken the tumeric and tamarind stew ( p < α 0,05). Its mean that the stew was efective to relieve dysmenorrhoea. Its recomended to female student to apply the tumeric and tamarind stew as herbal medicine to relieve the dysmenorrhoea

Efektifitas Terapi Musik Klasik terhadap Penurunan Tingkat Halusinasi pada Pasien Halusinasi Dengar di Rsj Tampan Provinsi Riau

The purpose of this research was to determine effectiveness of classical music therapy toward decrease level hallucination in patient with auditory of hallucination at RSJ Tampan Riau province. The research used quasy experimental design with pretest-posttest design with control group which divided into experimental group and control group. Sample of this research is 34 people devided into 17 people as the exsperimental group and 17 people as a control group with using purposive sampling of techniques sampling. Instruments of this research has been tested the validity and reability. The experimental group were given interventions with music therapy of five time in five days for 10-15 minutes. Then the data analyzed into univariate and bivariate using wilcoxon test and mean-whitney test. The result of the research showed there is significantly to contrast level of hallucination after given intervention between experimental group and control group with p value 0,000 (<0,05). In conclusion level of hallucination experimental group was lower than control group after given intervention. The result is expected of music therapy to be one nursing intervention to decrease level hallucination with auditory of hallucination
