<p><em>The use of pesticides in rice production has an impact on the environment. Pesticides are chemicals used to kill or control pests. The use of pesticides carries some risks, but farmers are used to using pesticides. However, the use of pesticides may lead to the contamination of groundwater. Therefore, the research question in this study was whether there any differences in rice production before and after pesticide reduction in Indonesia. This study aimed to analyze the difference between rice production before and after pesticide reduction in Indonesia. The secondary data in this study were rice production data from FAO. Data from 1968 to 1992 were data about rice production before reducing pesticide use in Indonesia, while data from 1993 to 2017 were data about rice production after reducing pesticide use in Indonesia. The applied data analysis was paired sample t-test using SPSS 25. The results indicated that there is a significant difference between rice production before and after reducing pesticide use in Indonesia. </em></p>

This research is aimed to find empirical evidence on whether there is a significant difference between Regionally-Generated Income (Pendapatan Asli Daerah, or PAD) before and after the shift of the collection of Land and Building Taxes for Rural and Urban Sectors (Pajak Bumi dan Bangunan sektor Pedesaan dan Perkotaan, or PBB-P2) to regional governments. PAD is measured by local revenue sources. Three regencies/municipalities that have experienced the shift during the 2011-2013 period were selected for sampling. Secondary data were obtained from Revenue Realization Reports (Laporan Realisasi PAD) of Yogyakarta for the years 2011-2013, Revenue Realization Reports of Sleman and Bantul for the years 2012-2013, and PBB-P2 and the Sales Value of the Tax Object (Nilai Jual Objek Pajak, or NJOP) data obtained from DPPKAD. Meanwhile, primary data were obtained through interviews conducted with the PBB-P2 tax officers. The findings showed a significant difference of PAD. This, however, was not due to the shift of PBB-P2 tax collection to regional governments. The difference was caused by other revenue sources.Keywords: PBB-P2 tax collection shift, PAD

Removal Technique

This study evaluated the influence of apical patency, root filling removal technique and cleaning of the apical foramen, concerning the amount of debris extruded during root canal retreatment. Forty mandibular incisors were randomly assigned to 4 groups - GIM (n=10), GIIM (n=10), GIPT (n=10) and GIIPT (n=10), which were named according to leaving (I) or not (II) apical patency during canal preparation and filling removal technique (manual - M or ProTaper system - PT). After filling material removal, each specimen of each group had the apical foramen cleaned by sizes 15, 20 and 25 instruments, generating 12 subgroups: GIM15, GIM20, GIM25, GIIM15, GIIM20, GIIM25, GIPT15, GIPT20, GIPT25, GIIPT15, GIIPT20 and GIIPT25. Extruded filling debris was collected by a Milipore filtration system, an HV-durapore, 0.45 µm pore filter with a 25 mm diameter. The filters were weighed before and after the collection on an analytical scale (10–5 g), and the difference was calculated. The mean weight of extruded filling debris was analyzed statistically by Kruskal-Wallis and Friedman ANOVA tests (α=0.05). The mean values found in the groups (in mg) were: GIM (0.95±0.94), GIIM (0.47±0.62), GIPT (0.30±0.31) and GIIPT (0.32±0.44). There was no statistically significant difference among any of the groups or subgroups (p>0.05). ProTaper provided the smallest amount of extruded filling material, regardless of presence or absence of apical patency, followed by manual technique, without and with apical patency. Additional amounts of debris were collected during cleaning of the apical foramen, regardless of the instrument, presence/absence of patency or root filling removal technique.
