Abstract

Perbanyakan vegetatif merupakan salah satu pilihan untuk memperoleh bibit unggul. Salah satu cara yang digunakan dalam perbanyakan vegetatif adalah dengan grafting. Perbanyakan tanaman durian dengan cara grafting sering mengalami kegagalan. Salah satu penyebab kegagalan grafting durian diduga karena pemilihan batang bawah dan batang atas yang kurang tepat.  Kendala yang sering dihadapi ketika melakukan penyambungan durian dengan metode sambung pucuk adalah jauhnya jarak antara pohon induk atau sumber entres dengan tempat penyambungan, sehingga dibutuhkan waktu yang agak lama mulai dari pengambilan entres sampai dengan proses penyambungan. Faktor lain adalah tanaman durian setelah berbuah mengalami  kondisi pertumbuhan vegetatif yang kurang baik digunakan sebagai bahan entres.  Selain itu  jumlah batang bawah yang akan disambung sering dalam jumlah yang sangat banyak, sehingga tidak bisa dilakukan penyambungan dalam waktu sehari dan entres yang belum tersambung harus disimpan untuk keesokan harinya baru dilakukan penyambungan. Disimpulkan Lama Simpan Entres berpengaruh nyata terhadap Persentase Sambung Hidup, Persentase Entres Dorman, Jumlah Tunas, Jumlah Daun, Diameter Batang, Luas Daun Total, Nisba Luas Daun, dan Nisba Pupus Akar.  Sumber Entres bepengaruh nyata terhadap Luas Daun Total dan Diameter Batang.  Persentase Sambung Hidup tertinggi dipengaruhi oleh Kandungan Karbohidrat, Persentase Entres Dorman tertinggi dipengaruhi oleh Kandungan Kadar Air, Jumlah Tunas tertinggi dipengaruhi oleh Kadar Air, Panjang Tunas tertinggi dipengaruhi oleh Kadar Air, Jumlah Daun tertinggi dipengauhi oleh Kandungan Kadar Air. Keberhasilan dan Kompatibilitas sambungan terbaik diperoleh dari perlakuan sumber entres yang berasal dari cabang sekunder  dan lama penyimpanan 4 hari.

Abstract

Pembibitan Durian dapat dilakukan dengan menggunakan sumber bahan generatif dan vegetatif. Kedua sumber propagasi ini memiliki kelemahan dan kekuatan masing-masing. Bibit berkualitas diperoleh melalui kombinasi dari dua sumber bahan perbanyakan yang memiliki masing-masing kelebihan yang dapat saling melengkapi. Proses penggabungannya bisa melalui mini grafting. Metode mini grafting di pembibitan durian dapat menggunakan cara  grafting samping dan grafting pucuk. Penelitian ini ingin mengkaji hubungan kandungan karbohidrat, protein, dan lemak terhadap keberhasilan pertumbuhan hasil mini grafting pada tanaman durian. Penelitian dilaksanakan dengan menganalisis kandungan karbohidrat, protein dan lemak pada batang atas yang akan digunakan untuk grafting, serta mengamati dan mengukur proses pertumbuhan tanaman hasil mini grafting.  Kandungan karbohidrat pada batang atas memberikan kontribusi positif tertinggi terhadap peningkatan jumlah tunas diikuti oleh jumlah daun, luas daun, perbandingan luas daun, perbandingan pupus akar, panjang tunas, dan diameter batang. Kandungan protein dan kandungan lemak tidak dapat berkontribusi pada pertumbuhan bibit okulasi bahkan memiliki kecenderungan untuk menghambat pertumbuhan.

Abstract

This study is carried out in chacthment area of Bodri. The goals of this study are to kno the influence of economic social condition of population on the change of the kind of landuse and the influence of the change of the kind of landuse on the run-off area. This study uses survey method. The collected data are the economic social data of the population and the physical condition data in the research area. The result of the study shows that the economic social condition of the population in chatchment area of Bodri influences on the decrease of landuse. The decrease in landuse is 22.27% which used settlement, dry land cultivation (3.14%), yard (1.07%), plantation (0.44%), wet land cultivation (2.28%), embankment (0.25%), street and others (6.73%). The decrease in landuse causes peak discharge of Hydrograph in 1997, 1999, 2000, and 2001 increases respectively 87.32 m/second, 101.26 m/second, 58.37 m/second, 89.82 m/second, with each volume of direct flow 7.123.392 m, 6.011.604 m, 11.784.672 m, and 9.459.954 m. The run-off coefficient in 1992, 1997, 1999, 2000, and 2001 increase 7.7%, 13%, 19.8%, 23.2%, and 27.03%, with coefficient of annual flow 46.98%, 72%, 55.21%, 61,79%, and 75.55%. The increasing of the run-off coeficient and annual flow describes that the ratio both the discharge of maximum and minimum monthly flow becomes bigger. It means that in rainy season it will be flood immediately and in dry season it will be drought easily.

Abstract

The study of impact of the banker of liquid organic fertilizer (POC) on groundwater is carried out in Sambungmacan Sragen. The banker is made of concrete cement and it is located in the settlement area. This bunker causes obstruction for population, such as the smell bad, many died cassava, plants, and well pollution. The source of these obstruction is the leakage that permeates on groundwater used for drinking water. The aims of this study are know 1) the apportion of the groundwater pollution; 2) the level of groundwater pollution of drinking water. The result of the study shows that POC has permeated two population’s wells that are located in radius eight meters. The water of wells is muddy and smells bad. Finally the well in north side of the banker is not used anymore, while the well in the west side of the banker, its water is still fresh after it has been drained twice. After the banker of liquid organic fertilizer (POC) is not be used anymore and the well which is polluted by POC has been drained, cause of that, the quality of groundwater in the research area generally still fullfills the requirement of drinking water, except the well in north side of the banker because it is polluted (the smell and color). So that, classification groundwater pollution in research area is still in very low level.
