Abstract

The research on erosion level (TBE) in the sub watershed of Tapung kanan has beenconducted on February-March 2013 using the USLE (Universal Soil Loss Equation) bythe formula A = RxKxLSxC.P. The results showed that the change of use / land coverimpact on the actual increase in the level of erosion that occurs in each type of landuse. Erosion hazard level (TBE) which occurs in the sub watershed of Tapung Kanan,for each type of use / land cover has a magnitude which varies, with an average erosionrate of 130.18 tons / Ha / year, and the distribution for each class TBE is: very Low(SR): 16986.50 Ha (7.17)%; Low: 35343.73 ha (14.92%); Moderate: 142,155.01 ha(60.01%); high: 32109.48 Ha (13.55%) and very high: 10290.71 ha (4.34%). TSL valueof Tapung Kanan Sub watershed which obtained from this research ranged from 14.40-30.00 tons / ha / year, while the average value of the actual erosion of 130.14 tons / ha/ year, thus the Erosion hazard level of Tapung kanan Sub Watershed exceeds thepermitted threshold, the SDR value of 0.463, still below the SDR standard value of0.490.

Abstract

Fokus penelitian ini berkenan dengan korelasi penerapan penilaian autentik mata pelajaran PAI dan budi pekerti dengan prestasi belajar di SMAN 1 Simpang Rimba kab.Bangka Selatan. Tujuan penelitian ini adalah untuk mendeskripsikan korelasi penerapan penilaian autentik mata pelajaran PAI dan budi pekerti dengan prestasi belajar peserta didik di SMAN 1 Simpang Rimba Kab. Bangka Selatan. Jenis penelitian ini adalah penelitian kuantitatif, dengan menggunakan metode korelasi. Populasi dar ipenelitian ini adalah peserta didik kelas XI IIS I di SMAN 1 Simpang Rimba Kab.Bangka Selatan Tahun Ajaran 2018/2019 yang berjumlah 33 peserta didik. Dan sampel penelitian ini berjumlah 33 peserta didik. Teknik pengumpulan data penelitian ini menggunakan teknik angket dan dokumentasi. Teknik instrumen penelitian menggunakan uji validitas dan uji reliabilitas data. Teknik analisis menggunakan analisis korelasi. Uji hipotesis yaitu dapat membandingkan nilait hitung dengan nilai ttabel. Setelah didapat inilait hitung sebesar2.076, berdasarkan data yang telahdipaparkan di atas, maka dapat disimpulkan bahwa thitung>ttabel dengan angka 2.076 > 1.697, berarti Ha diterima H0 ditolak. Namun bisa kita lihat bahwa hasil Correlations variabel X dan variabel Y. Nilai yang diperoleh sebesar 0, 377 berarti terdapat hubungan yang rendah antar penilaian autentik dan prestasi belajar. Ini berarti bahwa korelasi penilaian autentik mata pelajaran PAI dan budi pekerti dengan prestasi belajar peserta didik di SMAN 1 Simpang Rimba Kab.Bangka Selatan menunjukan korelasi yang rendah.

Abstract

The purpose of this research is to find out the correlation between attitude, learning style and numerical ability with the results of mathematics learning. This research method applied descriptive of correlation. The population in this research is grade VII SMP the district of Jetis Bantul, with a sample of 72 students taken by cluster random samplingfrom two state junior high schoolthat is SMPN 1, SMPN 2 Jetis and one private junior high school that is SMP Muhammadiyah. Analytical techniques multiple regression analysis with requirment of normality and linierity.Based on the results of the research, R = 0,427, meaning that there was a positive correlation between attitude, learning style and numerical ability with the results of mathematics learning. ry1-23 is 0,280, meaning that there was a positive correlation betweenattitude with the results of mathematics learning. ry2-13 is 0,271, meaning that there was a positive correlation between learning style withthe results of mathematics learning, ry3-12 is 0,242, meaning that there was a positive correlation between numerical ability with the results of mathematics learning.

Kegiatan Pengabdian kepada masyarakat (Pkm) ini bertujuan untuk melakukan sosialisasi dan memberikan Pelatihan kepada Pelaku Usaha Mikro, Kecil dan Menengah (UMKM) yang berlokasi di Kelurahan Binong, Kecamatan Curug. Salah satu masalah yang dihadapi oleh para pelaku UMKM yang sebagian besar telah memiliki NPWP, tetapi mereka tidak melaporkan pajak atas penghasilan yang diperoleh dari kegiatan usaha sebagai wajib pajak , hal ini disebabkan oleh karena minimnya pengetahuan pelaku UMKM tentang masalah perpajakan baik tentang peraturan, sanksi-sanksi yang diterapkan maupun tata cara perhitungan pajak tersebut terutama perhitungan dan cara pengisian SPT pajak penghasilan. Kegiatan Pelatihan tentang pengisian dan pelaporan SPT tahunan online tahun 2022 oleh wajib pajak orang pribadi melalui laman DJP online pelaku UMKM di Kelurahan Binong dilakukan melalui pendekatan ceramah, tutorial, diskusi dan praktik pengisian SPT secara online.

Abstract

This research was aimed to know the effect of concentration treatment young coconut water on the growth and result of three Varieties Land Water Spinach. This research was conducted from May until June 2021 at Cikupa, Tangerang. This Research used Randomized Completely Block Design (RCBD), consisted two factors. The first factor was concentration of young coconut water with four level, namely: K0 = control without concentration young coconut water, K1 = 225 ml concentration of young coconut water, K2 = 250 ml concentration of young coconut water, and K3 = 275 ml concentration of young coconut water. The second factor was Varieties of land water spinach with three level, namely: V1= Bangkok, V2= Bisi, V3=Bika. Each treatments repeated 3 times. Parameters observed were plant height, number of leaves, fresh weight per plant, and root long. The result showed that, 275 ml concentration of young coconut water gave the best result on the parameter plant height in 7 Day After Planting (DAP): 9,69 cm; 14 DAP (19,99 cm); 21 DAP (33,20 cm); and 28 DAP (47,03). The treatment of three Varieties, Bangkok gave the best result on number of leaves in 7 DAP (2,00 sheets). There were interaction between the treatment of concentration young coconut water and Varieties of land water spinach on the  parameter plant height (28 DAP) and number of leaves (7 DAP). Key Words: Young Coconut Water, Varieties of land water Spinach
