1. If H. pomatia are kept under conditions of constant temperature, humidity, illumination, food supply and water supply, their daily weight curves show great spontaneous fluctuations of an irregularly cyclical character, with a period of several days. Snails kept without food, but under otherwise identical conditions, show similar fluctuations of smaller amplitude (Fig. 1). 2. A number of measurements of the oxygen consumption of H. pomatia were made at different points on the weight cycle. In fed animals, oxygen consumption tends to rise with weight. In fasting animals, the relationship between the two variables is less marked, and the oxygen consumption is always low (Figs. 2, 3). 3. Aestivation tends to occur, even if environmental conditions are favourable, whenever the weight is low (Fig. 4). Feeding and digestion are apparently confined to the weight peaks, and incompatible with aestivation. 4. The interrelations of internal and external factors in determining the activity level of H. pomatia are discussed. In drought, the activity outbursts are inhibited and the snail remains withdrawn, with low weight and oxygen consumption. Rain, after drought, releases the cycles again; the immediate mechanism of activation is not hydration of the tissues, but a stimulation effect.

This study summerized that the determinants of the PPP Dadap's performance are internal and external factors, and organizational and social factors.<br />Key words: operational activities, PPP Dadap, multiple linear regression analysis</p><p>-------</p><p><br />ABSTRAK<br />Kepuasan para pengguna pelabuhan dapat dilihat dari kinerja pelabuhan tersebut. Tahun 2008, PPI Dadap berubah status menjadi PPP (Pelabuhan Perikanan Pantai). Namun peningkatan status tersebut tidak diikuti dengan peningkatan produksi ikan, dan aktivitas operasional pelabuhan perikanan. Perubahan status PPI menjadi PPP, tidak mengakibatkan peningkatan kinerja pelabuhan perikanan tetapi justru menurun. Oleh karena itu, penelitian ini dilakukan untuk mengetahui aktivitas operasional PPP Dadap setelah perubahan status, dan faktor-faktor penentu kinerja pelabuhan PPP Dadap. Analisa data dilakukan dengan dua metode; pertama metode deskriptif yaitu untuk menganalisa aktivitas operasional PPP Dadap; kedua metode statistik parametrik yaitu untuk mengetahui pengaruh faktor organisasi dan sosial terhadap kinerja PPP Dadap. Penelitian ini menyimpulkan bahwa penentu kinerja PPP Dadap adalah faktor internal dan eksternal, serta faktor sosial dan organisasi.<br />Kata kunci: aktivitas operasional, PPP Dadap, analisis regresi linier berganda</p>

The purpose of this study was to identify the internal and external factors associated with the implementation of the organization's policies. It was an applied-descriptive study conducted through a survey method using a questionnaire. For the purpose of this study, after reviewing the literature and theoretical foundations, we tried to identify the most important internal and external factors affecting optimal policy implementation. Therefore, seven factors and their indices were selected based on frequency and importance. In the form of seven hypotheses, the relationship between these factors and optimized policy implementation was evaluated. The statistical population included 120 employees of the Department of Natural Resources and Watershed Management of Khorasan Razavi province. The sample size was calculated using the Morgan formula to be 92 people. Regarding the fact that the policy implementation had an abnormal distribution, the nonparametric single t-test was used to test the hypotheses. The results indicated a positive and significant relationship between all internal and external organizational factors identified by optimal policy implementation in the organization.

ABSTRACTThe success in developing "Kampoeng Wisata Cinangneng (KWC)" can be seen from how the community participated in it. The purpose of this study was to analyze the level of community participation in developing “KWC”, analyze internal and external factors related to the level of community participation, analyze the success of “KWC”, and analyze the relationship between the level of community participation and the success of “KWC” development. This research was conducted in "Kampoeng Wisata Cinangneng", Cihideung Udik Village, Ciampea District, Bogor Regency. Respondents in this study were 50 people from Cihideung Udik Village who participated in the Development of “KWC”. The study showed that age (rs -0,288 ; p<0,05) and education level (rs 0,364 ; p<0,05) as internal factors are correlated to comunity participation stage (rs -0,160 ; p>0,005). Allso, correlation showed that external factors and the level of community participation (rs 0.562 ; p<0.05), such as the influence of driving actors (rs 0.508 ; p<0.05) and supporting facilities (rs 0.453 ; p<0.05). But, there is no correlation between the level of community participation and the success rate of developing "KWC" (rs 0.164 ; p>0.05). Although, there is correlation between of benefits of community participation stage and the success rate of developing “KWC” (rs 480 ; p<0.05). Keywords: society participation, the success of developing a “Kampoeng Wisata Cinangneng”. ABSTRAK                     Keberhasilan dalam mengembangkan “Kampoeng Wisata Cinangneng (KWC)” dapat dilihat dari seberapa berperannya masyarakat ikut berpartisipasi di dalamnya.
