Abstract

 ABSTRACTThe purpose of this research was to investigate the effect of five kind of soil enhancers to growth and yield of sweet corn plant grown on peat soil. This research was conducted on peat land located in Permata City Complex, Bansir Darat Village, Pontianak Southeast Subdistrict, Pontianak Regency, West Kalimantan Province. The study was conducted in December 2017 until February 2018 This research used field experiment with Randomized Block Design (RBD), with one factor, consit of 5 treatments and 5 replications, each treatment plot taken 4 plant samples. The treatment were: p1 = 2.5 kg of Dolomite Lime per block, p2 = 2.85 kg of Clam Powder per block, p3 = 4.56 kg burn of Ash Wood per block, p4 = 5,8 kg ash coconut husk per block, P5 = 7.12 kg of Palm Long Ash per block. Observational Variables observed were leaf area (cm2), root volume (cm3), dry weight (g), unsweethed cob weight per plant (g), cob length (cm), cob diameter (cm) and cob weight per block (kg) and the enviromental variables are Air Temperature (oC), Air Humidity (%), Rainfall (mm), and soil pH. Result of this research have significantly have to all observation variables. Based on the results of the study can be concluded that the provision of several types of soil enhancers apllied affect the growth and yield of sweet corn plants on peat soil. The burn of wood ash has a better effect when compared with other treatments on growth observations and sweet corn yields on peat soils.Keywords: Peat, ameliorant, and Sweet Corn.

Abstract

Tanaman sorgum adalah tanaman serelia yang banyak manfaatnya, namun belum banyak dikembangkan beberapa wilayah di Indonesia, karena faktor lingkungan seperti sebagian keadaan lahan yang belum sesuai untuk ditanamani sorgum. Pengembangan tanaman sorgum perlu dilakukan kegiatan pengujian dilapangan untuk menentukan varietas yang cocok disuatu lokasi seperti lahan gambut. Penelitian bertujuan untuk mengetahui varietas tanaman sorgum yang sesuai ditanam di lahan gambut. Penelitian dilaksanakan pada tanggal 22 Mei  – 20 September 2016 di Jl. Reformasi, Pontianak, menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari satu faktor, dengan 4 taraf perlakuan yaitu p1 (Numbu), p2 (Kwali), p3 (Super 1), p4 (Super 2). Masing-masing perlakuan di ulang sebanyak 6 kali. Variabel yang diamati dalam penelitian ini meliputi tinggi tanaman (cm), jumlah daun (helaian), berat kering tanaman (g), panjang malai (cm), berat biji per malai (g), berat per 1.000 biji (g) dan berat biji per petak (g). Hasil konversi per satuan luas/ Ha menunjukkan semua varietas, hasil yang diperoleh lebih tinggi dibandingkan deskripsi. Berdasarkan hasil penelitian beberapa varietas sorgum dapat tumbuh dan memberikan hasil yang baik pada lahan gambut.   Kata  kunci: Gambut, Varietas sorgum

Abstract

Di Indonesia karet alam merupakan komoditas strategis terutama ditinjau dari total area dan sumber devisa. Desa Sempadian merupakan salah satu daerah penghasil karet. Gulma yang tumbuh dipertanaman karet merupakan salah satu faktor yang dapat menurunkan kuantitas dan kualitas hasil. Struktur komunitas gulma perlu diketahui sebelum dilaksanakannya pengendalian gulma sebab tidak semua jenis gulma berbahaya bagi tanaman. Penelitian ini bertujuan untuk mempelajari dan mengetahui struktur komunitas gulma pada perkebunan karet  di desa Sempadian Kecamatan Tekarang Kabupaten Sambas. Penelitian ini bersifat deskriptif dengan cara melakukan pengamatan langsung di lapangan. Hasil pengamatan menunjukkan bahwa terdapat 30 jenis gulma dari 16 family. Pada areal perkebunan karet  TBM ditemukan 19 jenis gulma dari 11 family dan pada areal perkebunan karet TM ditemukan 19 jenis gulma dari 10 family. Spesies gulma yang paling dominan pada jalur tanaman TBM adalah gulma Ischaemum rugosum salisb dengan SDR sebesar 21.27% dan pada gawangan TBM didominasi oleh gulma Rhynchospora corymbosa dengan SDR sebesar 16.27%. Selanjutnya spesies gulma yang paling dominan pada Jalur tanamanTM adalah gulma Paspalum conjugatum dengan nilai SDR 42.44% dan pada gawangan TM didominasi oleh gulma Axonopus compressus SDR sebesar 22.11%.   Kata kunci : Gulma, Perkebunan karet, Struktur komunitas

Abstract

This research aims to develop and evaluate a geospatial application for groundwater resource management at Karanganyar Regency. The system development methodology from Whitten and Bentley (2007) was used in this research. To initiate the project, we discussed with the stakeholders from Karanganyar Regency which came from various related agencies followed by a focus group discussion (FGD) to analyse the system. Computational design and experiment were conducted to design the system prototype. Finally, we implement the system in the Regency. The result shows that the system is complex not only due to the managerial procedures but also the number of involved users (stakeholder) in the system. To address the emerged requirements from the FGD, we propose and develop a web-based GIS application with current open source technology and Google Map API which can be used for collaboration among stakeholders as well as for supporting the decision support purpose in the groundwater management. Currently, Air-tanah, the prototype of the application is available at http://geografi.ums.ac.id/air-tanah/. Both quantitative and qualitative evaluation of the system resulted good responses from the users.

Abstract

This study aims to reveal the effectiveness of science teaching based on project-based learning to improve ICT literacy learners in the junior high school with the category of high, medium and low. This research uses descriptive method to describe the students’ equipness of ICT literacy in the science learning based on the project-based learning that is integrated with e-learning. All of the population in this study are junior high school of curriculum pilot project in 2013 in Singkawang. The sampling in this study uses stratified random sampling to determine three of the four schools that represent the school with a category of high, medium and low based on the National Examination score on 2015, namely, SMPN 1 Singkawang, SMPN 3 Singkawang, and SMPN 7 Singkawang and from each school are randomly selected one class. The data collection is done by the observation and questionnaires of the students’ equipness in ICT literacy with effective criteria only if it is in a good or excellent criteria. Based on the analysis, project-based learning science-based learning is effective in equipping ICT literacy learners at junior high school  at the categories of high, medium and low.

Abstract

The number of verses of the Quran contained in the Qur'an, encouraging people to look for a way to get the exact clause in a short time. The science is an important knowledge, as Muslims we are obliged to study it with the Al-Quran as a guide. So that's how we get the verse about the science of the Quran with a quick, efficient and practical with a mobile application. Decision tree is a predictive model using a tree or hierarchical structure, this method can support mobile applications to be created. Because based decision very complex and global in the Quran, can be transformed into more simple and specific. C4.5 algorithm is a decision tree induction algorithm and is suitable to perform the classification process. The results of the percentage of successful applications created by using a decision tree that is 75.73%. From these results is known that the algorithm C4.5 and decision tree reasonably is well used in the classification process.
