No full textEFFECT CALCINATION TEMPERATURE ON FORMED OF CALCIUM SILICATE FROM RICE HUSK ASH AND SNAIL SHELL
No full textCalcium silicate ceramics have been made using natural ingredients such as rice husk and snail shell with solid reaction techniques. The aim of this study to determine the characteristics of calcium silicate that have been sintered at atemperature of 900 °C, 1000 °C, and 1100 °C. Samples were characterized by X-Ray Diffraction (XRD), optical microscopy, and Fourier Transform Infra-Red (FTIR). The XRD results showed that CaSiO3(calcium silicate) along with the increase in calcinationtemperature and quantity wasincreased due to the increaseof temperature ofcalcination. FTIR analysis showed that the Ca-Si-O bond was formed at wave number ranging from 848 cm-1and 999 –1001cm-1.Keywords:Calcium silicate;rice husk ash;the shell of a snail
Analisis Faktor yang Mempengaruhi Tingkat Efisiensi Teknis Usahatani Padi di Lahan Rawa Kalimantan Selatan
No full textProduktivitas usahatanipadi dapat ditingkatkan dengan penerapan teknologi maupun dengan peningkatan efisiensi.
Makalah ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi produksi usahatani padi.Penelitian ini juga
menganalisis faktor-faktor sosial sebagai penentu dari efisiensi teknis yang mempengaruhi kinerja petani dalam
melakukan usahataninya. Berdasarkan hasil penelitian didapat bahwa penggunaan benih, pupuk, dan tenaga kerja secara
signifikanmempengaruhiproduksi padi. Hasil penelitian ini juga menunjukkan bahwa umur, pendidikan, dan
pengalaman mempengaruhi tingkat efisiensi teknis, dimana efisiensi akan meningkat dengan ditingkatkannya tingkat
umur (dalam usia produktif), pendidikan dan pengalaman dalam berusahatani.

An Alternative Energy Produced from Kalimantan Local Comodities by Zero-Waste Production Process
No full textKalimantan is considered as a megadiverse island in the world because of its wide variety of species of plants. This potency must be managed to obtain optimum added values. In the Master Plan of Development and Acceleration of Indonesian Economic (MP3EI), Kalimantan was programmed to be the center of mining processing and national energy reservoir. Energy based on renewable resources must be continuallydeveloped. Tarap fruit (Artocarpus sp) is a typical fruit of Kalimantan, which the pulp part can be consumed and the seed can be processed for kind of flour, while it bark can be processed for briquette with addition of spent bleaching earth (by product of refinery process of palm oil production). The aims of this study was to obtain alternative energy, in form of briquette, based on Kalimantan local comodities through a zero waste production process. First of all, we optimized the formula of product, which consisted of two components: Tarap fruit waste and spent bleaching earth. Then the quality of each formula was examined. The optimum formula was obtained with its characteristics as follows: calorific value: >4700 kcal kg-1, combustion ashes : < 16.20 %, water content : 11 %, sulphur content : 0.0098 (< 1 %), and compressive strength value was 13.7 kgcm-2. Based on those results, the waste of Tarap fruit could be developed and used as a source of renewable briquette
An Exploration of the Performance between Shariah Banks and Conventional Banks During Global Financial Turbulence
No full textIt is believed that shariah banks have a higher resilience than that of conventional banks during global financial turbulence. However, this is not quite true. The objective of this paper is to explore the performance of shariah banks and conventional bank during the global financial turbulence since 2008 in terms of key financial indicators such as ROA,
NPL, BOPO, CAR and others.
The method of this study is descriptive analysis of some key financial indicators. The comparison of some key financial indicators during the global financial turbulence shows
the performance of both banks. The result of this study is mixed that there some key financial indicators are better on shariah banks than that of conventional banks, however,
some other indicators are much better on conventional bank than that of shariah bank.
Keywords: Shariah Bank, Conventional Bank, Global Financial Turbulenc
Exploring land cover changes in Satui Watershed of South Kalimantan through geographic information system (GIS)
No full textAbstract
Limited land resources affect the land conversion that causes the change in land cover
conditions, caused by the need for land, which is inversely proportional to the availability of
land. Land cover in the Satui basin in South Kalimantan province of Indonesia changed rapidly.
Community activities on the land have caused changes in the land cover that have negative
impacts on the sustainability of forest resources. Remote sensing and GIS are used to monitor
and evaluate land cover changes that occur in the Satui basin. Therefore, it is necessary to
monitor the suitability of land cover change to address the negative impacts caused by land
cover change, so that the carrying capacity of the land can be maintained as well as ascertaining
the extent of the land change since 2000 to 2014. The result of the land cover suitability
analysis in Satui watershed from spatial data of land cover according to the GIS interpretation
indicates 92% of the land as compliant with the land cover suitability standard and 8% as noncompliant.
Changes in land cover that occurred during the years 2000, 2003, 2006, 2009, 2011
and 2014 in the Satui basin in general include changes in land function; over each period the
land was affected by a decline in forest cover as they were being turned into commercial
plantations, and more land was opened for various human activity.
Key words: Land cover, GIS, Satui Watershed
Tinjauan Ketimpangan Ekonomi di Negeri-Negeri Islam
No full textSecara umum negeri-negeri Islam telah menjalani pembangunan lebih dari setengah abad sejak kemerdekaannya. Dari 57 negeri-negeri Islam yang menjadi anggota Organisasi Konferensi Islam (OKI), 7 diantaranya berhasil mencapai tingkat kesejahteraan rata-rata sangat tinggi (high income), 32 terkatagori negara dengan pendapatan menengah (middle income), dan 18 berpendapatan rendah (low income). Negeri-negeri Islam juga berhasil mengurangi tingkat kemiskinan ekstrim dari 41,15% pada tahun 1990 menjadi 23,22% pada tahun 2010. Meskipun demikian, negeri-negeri Islam tersebut menghadapi masalah ketimpangan ekonomi (economic inequality).
Paper ini bertujuan untuk memberikan gambaran bagaimana ketimpangan ekonomi di negeri-negeri Islam. Hasil kajian menunjukkan tingkat ketimpangan ekonomi di antara negeri-negeri Islam semakin meningkat baik ditinjau dari sisi kelompok pendapatan maupun dari sisi kelompok geografis. Jika ditinjau dari aspek distribusi pendapatan, indeks gini ratio di negeri-negeri Islam berada di antara 30-50 di mana proporsi pendapatan 20% penduduk paling kaya mencapai 4 sampai26 kali lipat proporsi pendapatan 20% penduduk paling miskin.
Katakunci: negeri-negeri Islam, ketimpangan ekonom
