Abstract

The effectiveness of new mathematics, which has been implemented in Indonesia for 29 years, in increasing student achievement is still in question. Starting from two or three years ago, Indonesia has tried out a new kind of approach in teaching mathematics, the so called Realistic Mathematics Education (RME). This article portrays the similarities and differences between these two approaches, discussing the strengths and weaknesses of each approach.

Abstract

Setiap tahun wilayah kumpeh selalu mengalami kebakaran hutan  yang berdapak pada  banyaknya asap yang ditimbulkan,  ditambah lagi  kebiasaan masyarakat dalam pengolah  lahan pertanian dengan membakar   dengan alasan lebih mudah, murah dan sisa pembakaran bisa menjadi pupuk. Namun sebagian besar wilayahnya terdiri atas lahan gambut yang mudah terbakar jika terjadi kemarau dan api sulit dikendalikan. Tentunya ini menjadi masalah sekaligus tantangan untuk bisa merubah pola pengolahan lahan yang selama ini dilakukan kearah yang lebih baik (Intended-Change).  Survei pendahuluan, wawancara dengan masyarakat dan kelompok tani di  Kumpeh Ulu bahwa  kebiasaan masyarakat  sudah turun temurun dilakukan yaitu  membakar lahan 1-3 minggu  dengan cara menunpuk  tanaman semak yang sudah ditebas, kemudian ditutup  tanah dibagian atasnya  dan dibakar sampai semua  sisa tanaman habis. Namun karena lahanya berupa gambut, maka  tanah bagian atas juga merupakan bahan yang siap terbakar. Padahal selama proses pebakaran ini terjadi pencemaran udara karena tingginya kandungan asap, sulit mengendalikan api jika sudah melebar. Potensi yang sangat menunjang dalam proses pengolahan lahan yang ramah lingkungan adalah melakukan pengolahan  limbah kotoran ternak dan limbah tanaman yang ada menjadi pupuk organik. Karena selama ini petani peternak tidak mengetahui pengolahan kotoran ternak menjadi pupuk bahkan kotoran ternak yang ada dibuang begitu saja disekitar kandang yang juga mengakibatkan pencemaran udara dan air. Padahal jumlah ternak yang dimiliki  kedua kelompok tani (sumber rezeki dan karya tani)  tergolong banyak yaitu sapi 37 ekor dan kambing 66 ekor. Potensi kotoran dari ternak ini sekitar 851 kg per hari dalam bentuk basah dari sapi dan sebanyak ± 30 kg per hari dari kambing. Tentunya ini merupakan bahan baku yang bisa dimanfaatkan selain sisa atau limbah  tanaman hultikutura yang ada.   Kegiatan penyluhan dilakukan di rumah ketua kelompok sumber rezeki yang diikuti sebanyak 22 onggota kelompok tani. Materi yang diberikan pada kegiatan penyuluhan ada 3 yaitu karerateristik lahan gambut, proses pembuatan pupuk organik dari kotoran ternak dan hijauan serta materi dampak asap pembakaran terhadap kesehatan. Selain penyuluhan juga ada praktek pembuatan pupuk organik sebanyak 1 ton, dengan menggunakan 600 kg kotoran kambing, 400 kg rumput yang sudah dicacah, ditambah dengan 1 liter EM4, 5 kg dedak padi dan 2,5 kg urea. Semua bahan diaduk rata dan disimpan selama 21 hari dengan cara ditutup tarpal. Hasil evaluasi kegiatan pengabdian bahwa pupuk organik yang dihasilkan memperlihatkan bentuk fifik yang baik yaitu berwarna coklat sampai kehiataman, berbauk tanah dan bertektur gembur.

Abstract

In the past, most people believed that calculators were useful only for obtaining or checking answers to computation problems. Therefore, in many ways they have often been ignored as a teaching resource. Based on the lack of interest, some parents and teachers have shied away from calculators use, especially in primary mathematics. Many researchers have also found that using calculators as a teaching aid is most useful and effective in developing number sense and mental computation. The Calculator-Aware Number (CAN) project in Britain found that children develop their own strategies for carrying out calculations and achieve a high level of numeracy when using calculators

Abstract

Deforestation and fragmentation of mangrove forests in Indonesia are widespread that resulted in losing biodiversity including genetic variation. Rhizophora mucronata Lamk. is a common mangrove species in Secanggang, Langkat, North Sumatra and have been degrading due to anthropogenic disturbance. The aim of this study is to determine the genetic variation in natural population of R. mucronata in Secanggang, North Sumatra using isozyme markers. From five enzymes systems used namely aspartate aminotransferase (AAT), alcohol dehydrogenase (ADH), esterase (EST), malate dehydrogenase (MDH), and peroksidase (PER); eleven loci was found and five polymorphic loci were detected.The estimate value of genetic variation parameters i.e. observed and expected heterozygosity, average alel per loci, and average polymorphic (95% criteria) were 0.1386, 0.1724, 1.5455, and 45.45 % respectively.The low genetic variation of R. mucronata found in this study suggested that genetic variation may be influenced by anthropogenic activities such as illegal logging, conversion into shrimp pond and agricultural farm.Keywords: Anthropogenic, genetic variation, isozyme, mangrove, Rhizophora mucronata

Abstract

Land of coal post-mining is the critical area that generally can not be cultivated due to very low levels of fertility of the land, so this land becomes slighted. One of the alternatives to overcome this problem is through inoculation with Arbuscular Mycorrhiza Fungi (AMF).  Indigenous AMF (from coal post-mining location) is more potential AMF developing in that area. Therefore, isolation, identification and purification steps of AMF spores are required. The objective of this study was to isolate, identify, and purify of arbuscular mycorrhiza fungi from coal post mining area. The study had identified that at this soil was found 3 AMF genuses, i.e. Glomus, Acaulospora, and Gigaspora.  On coal post-mining soil was found 20 strains of AMF (13 strains of Glomus, 3 strains of Acaulospora, and 1 strain of Gigaspora).  In this soil was dominated by Glomus. Strain’s AMF that was successful isolated from single spore culture was 4 strains i.e. Glomus sp-3, Glomus sp-6, Glomus sp-15, dan Glomus sp-16.   Key words:  isolation, identification, purification, coal post-mining, AMF

Abstract

This study is aimed at investigating how the English-Indonesian bilingual speakers use language codes in their interaction through internet. The data for this study comprised a linguistic corpus made up from postings send to a newsgroup by its members. The findings showed that codeswitching accured in this forum was similar to that in the face to face interaction. The code choice may be either marked or unmarked. The unmarked switching occured during informal and relax interaction. While the marked switching occured when the speakers wanted to negotiate a new right and obligation, specifically when they wanted to show anger, attract attention, make correction or invite another speaker to join.
