The study was conducted at WKPP Cicadas, in Binong, West Java in 1992. Ninety five farmers were selected by Stratified Random Sampling technique, were interviewed. The purpose of the study was to determine the optimum cropping pattern through the applicati In of the linear programming model. The result ofthe study showed that farmers did not use their resources optimally, i.e their income could still be increased by excuting optimum cropping pattern. Cropping pattern that was recommended for small size land was Rice + Fish - Fish - Rice + Fish - long bean, while that for large size land was Rice + Fish - Rice + fish - fish and long bean. Compared to the actual cropping pattern excuted by farmers, the recommended cropping pattern will increase farmer's annual income as much as 75% (or Rp 408,277), and 24.8 % (or Rp 514,642), for small size and large size land, respectively. Land and capital were the scarce resources for farmers as shown by the, nonzero shadow price value. Family labors were avalaible for farming in every activity needed. The result of the sensitivity analysis showed that for small size land, changes • in commodities price did not affect the optimum cropping pattern, while for large size land, ten percent decrease in pricewill change the optimum cropping pattern.
- ItemPEMUPUKAN KALIUM PADA PADI GOGO DI LAHAN KERING BERIKLlM BASAH KALIMANTAN SELATAN (Vol. 5 No. 1 1994)(Balittra, 1994-06) Achmadi Jumberi, Murjani Imberan, Nurita, Balittra; BalittraPotassium fertilizer application for upland rice on dryland- wet climate of South Kalimantan. Potassium fertilizer experiments on upland rice were conducted at Bumi Asih, Pelaihari during rainy season of 1992/1993. Two experiments have been conducted to study: (1) The effects of KGI fertilizer and ash of husk on upland rice; and (2) The application time and dosage of potassium fertilizer for upland rice. The first experiment used RGBD with three replication, and the second experiment used factorial treatment in RGBD with four replication. Laut tawar variety is grown at plot size of 8.5 x 6.0 m and 5.0 x 6.0 m for the first and second experiment, respectively. All plots were treated with NP (90-90) and applied in furrow along the rows of rice plant. The results of the experiment indicated that: (1) KGI fertilizer and ash of husk can increase K availability in the soils, and affected the growth and yield of upland rice in dryland-wet climate. (2) The basal application of potassium fertilizer was as good as the split application (basal and 30 day after planting) on growth and yield upland rice. (3) The yield of upland rice at 60 kg/ha K20 (3.31 t1ha and 3.52 t1ha) was as high as yield of upland rice at 90 kglha and 120 kglha K20. (4) The muriate of potash increase yield higher than that of ash of husk. (5) Upland rice showed linear respons to ash of husk with dosages up to 300 kg/ha. PENDAHULUAN
- ItemPersepsi Konsumen Terhadap Zat Tumbuh "Alar" dan Pengaruhnya Terhadap Pembelian dan Konsumsi Apel (Vol. 5 No. 1 1994)(Balittra, 1994-06) M. Y. Maamun, Agricultural EconomistPenelitian ini mencoba mengungkapkan reaksil persepsi konsumen terhadap "Alar" suatu zat tumbuh yang digunakan pada apel yang berpotensi sebagai penyebab penyakit kanker pada konsumen. Konsumen telah memperoleh banyak informasi berbeda-beda tentang zat tumbuh "Alar" baik dari kelompok pengacara, produsen dan pedagang ape\.Pertanyaan apakah konsumen merubah pola konsumsi terhadap ape\. Pengamatan juga dilakukan terhadap faktor- faktor sosial ekonomi Gender, pendidikan dan pendapatan) yang dapat mempengaruhi konsumsi apel serta pengetahuan yang berhubungan dengan sumber informasi dan pola konsumsi. Didalam mengevaluasi dampak informasi tentang ,-,Iar terhadap pembelian apel, 6 hipotesis yang dikembangkan dan di uji melalui 59 pembeli apel sebagai contoh di wilayah East Lansing, negara bagian Michigan, Amerika Serikat. Ke 59 sampel dipilih dengan menggunakan metoda non-probability-sampling yang diinterview oleh enumerator tentang pola konsumsi apel, sumber informasi tentang Alar dan pengetahuan tentang kimia. Reaksi konsumen terhadap resiko kesehatan dari bahan makanan menunjukkan bahwa hampir semua responden (99%) tahu tentang Alar, namun hanya 20% yang mengurangi konsumsi ape\. Pada umumnya, konsumen merasa khawatir atas peringatan-peringatan kesehatan ketika memperoleh banyak sumber informasi. Pada saat media mulai reda, kekhawatiran konsumen mulai menurun. Pengaruh media hanya pada periode tertentu yang pada akhirnya akan terlupakan dan menjadi tidak efektif.
- ItemPENGARUH ZEOLIT PADA PENYIMPANAN JAGUNG VARIETAS KALINGGA DAN GENJAH KRETEK TERHADAP Sitophilus zeamais Motsch (Vol. 5 No. 1 1994)(Balittra, 1994-06) Herawati Ida Staf Peneliti Mekanisasi dan PascapanenThe effect of zeolit dust in the storage of Kalingga and Genjah Kretek varieties of maize on Sitophilus zeamais Motsch. Zeolit dust of 0, 5, 10 and 15% were applied to maize seeds which then infested with five fairs of Sitophilus zeamais Motsch. Determination were made on the mortality rate of the Sitophilus zeamais Motsch, free fatty acid values, moisture content, viabilities, flavor and taste of the maize seed at 4, 8, 12 week storage time. The result showed that zeolit treatment at 5% or above cause high mortality rate of the Sitophilus zeamais Motch, while the free fatty acid value and moisture content of the seeds remained low, seed viability was high and their organoleptic properties remained good (acceptable for home consumption).
- ItemTOLERANSI BEBERAPA GENOTIPE KACANG TANAH TERHADAP TANAH MASAM PODSOLIK MERAH KUNING (Vol. 5 No. 1 1994)(Balittra, 1994-06) Koesrini, Sabran. MTolerance of several peanut genotypes to acidic redyellow podsolic soils. Thirty nine peanut genotypes were tested for their tolerance and yield potential on red-yellow podsolic soils. The experiment was carried out at farmer's field at Pleihari, South Kalimantan in 1993/1994 wet season and was arranged in a split plots design with 3 replications: The main plot treatments were lime application with two levels, i.e. no liming and liming at 2.0 t/ha, while the subplot treatments were the thirty nine genotypes. Of the thirty nine genotypes tested, 19 genotypes showed tolerance to acid soils with high yielding potential and good seed performance. There are 4 out of 19 genotypes, i.e. LM/ICGV 86021-88-8-29, LMIICGV86021-88-C-16, K/SHM2-88-C-7 and LMI ICGV86021-88-C-33, yielded from 2481 kg/ha to 2959 kgl ha. Response of genotypes to the two liming treatments were highly correlated which support the result of no interaction between liming treatments and genotypes.This implies that, as far as selecting high yielding genotypes is • concerned, rate of liming treatment on testing sites will have no effect
