Abstract

Padi dihadapkan pada isu global seperti penggunaan bahan sintetis dalam proses usaha tani yang dapat mengurangi kualitas lingkungan maupun produknya. Sebaliknya, beberapa penelitian menyatakan bahwa penggunaan bahan alami yang hemat biaya dapat meningkatkan pendapatan petani maupun menjaga kondisi lingkungan. Penelitian ini bertujuan untuk mengetahui biaya dan pendapatan usaha tani, mengetahui kelayakan usaha tani, mengetahui nilai tukar petani serta mengetahui faktor-faktor yang mempengaruhi produksi pada usaha tani padi organik di Kabupaten Sleman. Penelitian dilakukan terhadap 30 sampel rumah tangga tani padi organik dengan metode proportional random sampling. Analisis kelayakan usaha tani didapat melalui analisis R/C ratio, sedangkan faktor-faktor yang mempengaruhi produksi padi organik didapat melalui metode Ordinary Least Square (OLS). Hasil penelitian menunjukkan bahwa usaha tani padi organik di Kabupaten Sleman layak untuk dikembangkan. Luas lahan dan pendidikan kepala keluarga merupakan faktor yang berpengaruh terhadap produksi padi organik.

Abstract

Barangay Malinta has a regular garbage waste collection schedule. Biodegradable wastes are collected on Mondays, Wednesdays, and Fridays while non-biodegradable wastes are collected on Saturdays. The barangay is compliant to the RA 9001 (Solid Waste Management) however, they do not have a Material Recovery Facility (MRF). The absence of MRF is due to geographical location of the barangay which prohibits the establishment of the MRF facility due to its proximity to Laguna bay. The study aims to determine the perception of the respondents regarding the Clean-up Drive activities at the Saran River and to integrate it with the recommendations to aid in the improvement of the cleaning efforts for the said river, particularly at Barangay Malinta, Los Baños, Laguna, Philippines. Random sampling was used to identify residents to be included in the survey. The data were analyzed using percentage and mean. The results showed that the level of awareness among respondents residing Saran river is high. In terms of attitude, most of them strongly agreed that there will be a clean-up in the river and penalized those who will throw their waste in the river, most of the respondents are satisfied with the on-going river clean-up and optimistic that the river can still be cleaned and revived, and most of the respondents are willing to contribute amount and will be paid in the barangay as funding to river clean-up.

Abstract

Climate variability is one of the factors that directly and greatly affect cropping system and plant yield. It is therefore very important to obtain a good understanding about climate variability or changes in the climate and the effect of these changes to clearly understand the vulnerability of food crops as well as its agronomic impacts for us to create and implement adaptive strategies to mitigate its negative effects. This study assessed the effect of climate in rice crop yield in both irrigated and rainfed ecotype farming system in Nueva Ecija Province in the Philippines using semi-annual yield data and the different climate variables such as seasonal rainfall, mean temperature, minimum temperature, and relative humidity by using empirical/statistical method through time series analysis, and correlation analysis. Results indicated that rice yield for irrigated and rainfed ecosystem type of farming in Nueva Ecija show an overall increasing trend from year 1991-2018, although there are observed decline and fluctuations in some years. The different climate variables (i.e., rainfall, temperature, and humidity) show fluctuating trends and irregularities spanning from the year 1991-2018. But it showed overall decreasing trends for relative humidity and increasing trends for rainfall, minimum temperature, and mean temperature. There are significant correlations between rice yield the all the climate variables in both irrigated and rainfed farming ecosystem types.
