Abstract

This study aimed at detecting the presence of groundwater in Masda Makmur Village, Rambah Samo District, Rokan Hulu Regency, using the Schlumberger configuration geoelectric method. The study consisted of 3 sounding points within every 100 m sounding track length. The measurement data is processed using IP2WIN software and Progress to see layer data below the ground level based on the value of the resistivity type. The results showed that the estimated groundwater could be found on track one with a kind of resistivity value of 7,44 Ωm at a depth of 15-22 m. Alleged groundwater can be found on the second track with a type of resistivity value of 75,73  Ωmat a depth of 13-18 m, and the estimated groundwater can be located on the third track with a kind of resistivity value of 82,52 Ωm, 93,26 Ωm. The deeper and the lower resistivity value shows that the layer has the potential as a carrier layer of groundwater (aquifer). Sounding 1 and 2 have the potential to make bore wells which are thought to be depressed aquifer. The results of this study can be used further for mapping the location of community boreholes

Abstract

Cijeruk known as a strategic location that is still very close to the Mount Salak area, but also close to the urban area of Bogor itself. This causes the area to have the potential to have good water absorption, but it also has the potential to be disturbed by water absorption due to internal and external factors in the research area. For this reason, it is necessary to know the water absorption and infiltration rate in order to see the advanced conditions of the research area. In order to know this, researchers need to obtain primary data by processing in the field using a Double Ring Infiltrometer (Indonesian National Standard, 7752:2012); while secondary data were obtained from previous researchers, as well as official bodies in Indonesia. The rainfall at the nearest Citeko station per 5 years reaches more than 3000mm, namely 3168.8mm, indicating that the research area has a very high potential for rainfall. In addition, it can be concluded that the research area has a type of overburden in the form of loamy sand with flat to steep areas in 4 observation locations, while the other 5 observation locations are flat to very steep. Then, the results obtained in the Cijeruk area obtained 2 units of infiltration rate, namely sufficient infiltration rate with an infiltration rate of 0.192 m/day to 0.312 m/day and a high infiltration rate with an infiltration rate of 1.08 m/day up to 5.04 m/day. indicates that the water catchment area is classified as good.

Abstract

The increasing number of inhabitant in Sukacai village, Jiput – Pandeglang leads to the risen of clean water demand. However, along with the raising of demand, the groundwater availability has decreased. During the dry season, the water quality is poor and the rate of flow tends to be critical. As a consequence, the community is suffering from the scarcity of clean water supply for daily consumption and household necessity. This community service program aims to fulfill the needs of groundwater supply by applying the geophysical method, to recommend the depth of aquifer and construct the well of groundwater. The method is carried out using geo-electrical instruments to reveal the depth of aquifer as the source of groundwater. Another social approach is performed by educating the community about the optimization of well construction, as well as the effect of shallow and deep well construction towards the rate and quality of groundwater. The session has been wrapped with sharing and discussion. As a result, the authors recommend the depth of well construction is approximately 20 m for shallow well and 50 m for moderate well. The moderate well option is more recommended to avoid any contamination of pollution source as well as to maintain the flow rate during dry season.

Abstract

Permasalahan pendidikan yang mendasar sering berkaitan dengan penanaman pemahaman konsep yang kadang-kadang keliru. Suatu kesalahan dalam memahami konsep yang ditunjukan dengan kesalahan saat mengungkapkan ataupun menjelaskan suatu konsep dan tidak sesuai dengan teori ilmiahnya disebut miskonsepsi. Tujuan dari penelitian adalah Menganalisis Miskonsepsi Pada Konsep Gerak Lurus Menggunakan CRI Kelas X SMA N 2 Ujung Batu. Jenis penelitian ini adalah menggunakan penelitian deskriptif. Populasi penelitian ini adalah kelas X SMA N 2 Ujung Batu, sedangkan sampelnya yaitu kelas X MIA 1 SMA N 2 Ujung Batu. Teknik pengambilan sampel menggunakan simple random sampling yaitu pengambilan anggota sampel dari populasi dilakukan secara acak tanpa memperhatikan strata yang ada dalam populasi tersebut. Dari hasil penelitian didapatkan siswa yang mengalami miskonsepsi sebesar 36,67 % dan persentase tingkat pemahaman siswa yang paling kecil terletak pada kategori “paham konsep tetapi kurang yakin” dengan rata-rata persentase 6,06 . Sedangkan rata-rata persentase pemahaman siswa pada kategori paham konsep dan tidak tahu konsep yakni sebesar 35,15  dan 22,12 .
