Abstract

Palynology is a study of biostratigraphy for determining relative age and depositional environment basedon the abundance of palynomorf. Palynology study develompent in Indonesia is still could be more increasedalong with more oil and gas exploration moved to transitional environtment.Study of palynology in stratigraphy is aiming to determine relative age and depositional environment.Besides, palynology could also determine sequence stratigraphy in a large scale of study based on palynomorfpercentage. The study of sequence stratigraphy based on palynomorf percentage has been done in Well-Y, SouthSumatra basin.The method of this research is descriptive method through the microscopic observation on sample 1 - 14from 1400 m depth Y-Well’s cutting and quantitative method calculation and analysis method from thisobservation and calcuation could determine the percentage of each palynomorf. This percentage lead to a trendthen interpretated into several sequencestratigraphy.From this observation, it can be determined characteristic zone of this well. The characteristic zone ofpalynology in this well is divided into 3 zones of palynology; Proxapertites operculatus Zone, Flocshuetziameridionalis Zone, and Stenoclaeniidites papuanus Zone. Each zone shows the characteristic of age fromEocene to Pliocene and also depositional environment from delta plain to pro delta. From palynomorfpercentage trend, we may also see the pattern of sequece stratigraphy works in this depth. The percentage trendshows the time whether sea level fall at the minimum percentage of palynomorf and sea level rise at themaximum percentage of palynomorf. The trend shows the sequence with sequence boundary lying in the startand the end of the sequence and also transgressive surface indicates the sea level start rise. Overall, this wellhas 5 sequences based on this trend; sequence a, sequence b, sequence c, sequence d, and sequence e and all thesequences are bordered by sequence boundary.

Abstract

Budaya merupakan sebuah hal terpenting yang ada pada struktur masyarakat. budaya berkontribusi dalam bagaimana manusia hidup, bagaimana mereka berperilaku, serta di samping itu juga berpengaruh terhadap bagaimana mereka memandang diri mereka sendiri. Penelitian ini dibuat untuk menemukan jawaban mengapa banyak sekali masyarakat Minangkabau yang merantau dan berdagang. Tujuan dalam penelitian ini yaitu mengetahui nilai-nilai sosial budaya etnis Minangkabau yang menunjang kegiatan berdagang dan menerapkannya di kehidupan. Berdagang dan merantau menjadi kebiasaan yang dilakukan oleh para leluhurnya dahulu dan hal itu menghasilkan sebuah nilai-nilai yang dipakai oleh masyarakat Minangkabau sebagai pedoman bagi mereka. alasan yang membuat mereka melakukan kegiatan berdagang ada yang bersifat alasan umum, dan ada juga alasan yang didasari atas aspek-aspek budaya mereka. namun dalam hal ini, merantau memiliki potensi memudarkan nilai-nilai sosial budaya yang ada pada masyarakat Minangkabau. namun hal tersebut nampaknya dapat teratasi oleh sifat inklusifitas masyarakat Minangkabau di tanah rantau. Kata kunci : Minangkabau, merantau, berdagang, nilai, sosial, budaya,   masyarakat

Abstract: Continuous heavy rain on the slopes and some large tree roots that do not penetrate the slip surface can lead to progressive failure of landslide slopes. This is due to the large trees located at the top and the middle of the landslide area can reduce the stability of the slope. Various factors such as mechanics and hydrology in determining slope stability need to be considered. The phenomenon and mechanism of bamboo tree factors that lie below the slopes as the focus of research on root tensile strength of root-soil interacting. This study aims to determine the pull force and tensile strength due to root-soil interaction to the contribution of shear strength in the lower slopes. Field testing uses the root pull method by observing the diameter and number of roots. The test was performed with a tripod device equipped with strain gauge as a recording instrument on saturated soil conditions. The soil samples were taken from the study site to test the physical and mechanical properties of the soil. The result of the test shows that the soil type at the research location is inorganic silt. The results showed that the root pull force increased significantly against the increase in the number and diameter of the roots. In contrast, the tensile strength of roots in any land area decreases with increasing number of roots. Based on the graph shows that the number of roots more than five began not significant to tensile strength. Apparently, bamboo roots are dense and spread below the slopes, then the tensile strength of the roots that interact with the soil begins to stabilize. The tensile strength of the bamboo root results in additional cohesion valuesKeywords : root tensile strength, cohesion addition, soil shear strengthAbstrak: Hujan lebat yang berkelanjutan pada lereng dan sebagian akar-akar pohon besar yang tidak menembus bidang longsor (slip surface) dapat menyebabkan terjadinya kegagalan progresif terhadap longsoran lereng tanah. Hal ini, disebabkan karena pohon besar yang terletak di bagian atas dan tengah bidang longsor dapat mengurangi stabilitas lereng. Berbagai faktor  seperti mekanika dan hidrologi dalam menentukan stabilitas lereng perlu dipertimbangkan. Fenomena dan mekanisme faktor pohon bambu yang berada di bawah lereng sebagai fokus penelitian mengenai kekuatan tarik akar yang berinteraksi akar-tanah. Penelitian ini bertujuan untuk menentukan gaya cabut dan kekuatan tarik akibat interaksi akar-tanah terhadap kontribusi kuat geser di lereng bagian bawah. Pengujian di lapangan menggunakan metode gaya cabut akar dengan mengamati variabel diameter dan jumlah akar. Pengujian dilakukan dengan alat tripod yang dilengkapi strain gauge sebagai instrumen pencatat pada kondisi tanah jenuh. Sampel tanah diambil dari lokasi penelitian untuk dilakukan pengujian sifat fisis dan mekanis tanah. Hasil penegujian menunjukan bahwa jenis tanah pada lokasi penelitian adalah lanau anorganik. Hasil penelitian menunjukan bahwa  gaya cabut akar meningkat sangat signifikan terhadap pertambahan jumlah dan diameter akar. Sebaliknya, kekuatan tarik akar dalam setiap luasan tanah menurun seiring bertambah jumlah akar. Berdasarkan grafik menunjukan bahwa jumlah akar lebih dari lima mulai tidak signifikan terhadap kekuatan tarik. Ternyata, perakaran bambu yang padat dan penyebaran di bawah lereng, maka kekuatan tarik akar yang berinteraksi dengan tanah mulai stabil. Kekuatan tarik akar bambu menghasilkan nilai kohesi tambahan kepada kuat geser akibat interaksi dengan tanah terhadap stabilitas di bawah lereng.Kata kunci : kekuatan tarik akar, kohesi tambahan, kuat geser tanah

Abstract

This paper intends to see the literacy pedagogy in Indonesia from the point of view of transformative pedagogy of multiliteracies (Cope and Kalantzis, 2009). It can be argued that the educational change in Indonesia is moving away from the overt instruction (conceptualizing) orientation of literacy pedagogy to the transformed practice (applying) orientation of literacy pedagogy. Beside the convincing argument that this change is needed, there are several challenges in applying this practice in the classroom and one of it is the cultural constraint. This paper will try to describe Indonesian culture of learning as the basic argument of cultural constraint challenges and as an attempt to see the literacy movement in Indonesia from the sociocultural perspective of educational change. This description will then help framing the implications both for teachers as the agent of change and for government as on how to manage the change. Data and support written in this article are from secondary sources as this article intends to be a literature review. Suggestions coming from the literature discussed that a ‘collaborative work culture’ (Fullan & Hargreaves, 1992) is the solution of the challenge in implementing a transformative pedagogy of multiliteracies in Indonesian context.
