Abstract

Kegiatan penelitian survai konsumen dilaksanakan di Kelurahan Sukasari dan Lembang, Bandung, Jawa Barat pada bulan Agustus-November 2004. Responden dipilih menggunakan metode multistage cluster sampling. Responden ibu rumah tangga sebanyak 50 orang dipilih secara acak dan proporsional dari kedua kelurahan tersebut. Pengumpulan data dilakukan melalui wawancara menggunakan kuesioner terstruktur. Pada studi awal ini komoditas sayuran minor (under-utilized) yang dipilih adalah koro/roay jengkol, katuk, kecipir, dan labu siam. Untuk keperluan mempelajari posisi sayuran minor tersebut dipilih pula 4 komoditas lain yang dapat dianggap sebagai padanan atau substitusi, yaitu kacang jogo, bayam, kacang panjang, dan zukini. Atribut produk yang dipelajari meliputi (a) kandungan gizi tinggi, (b) berfungsi juga sebagai obat, (c) rasa enak, (d) tahan simpan, (e) harga mahal, dan (f) mudah diperoleh di pasar. Penelitian ini diarahkan untuk mengidentifikasi segmentasi pasar dan memetakan persepsi konsumen menyangkut beberapa atribut produk sayuran minor. Hasil penelitian mengidentifikasi 2 klaster atau segmen konsumen untuk setiap komoditas dengan karakteristik yang berbeda. Jumlah anggota klaster 1 secara konsisten selalu lebih besar dibandingkan klaster 2 untuk semua komoditas, sehingga upaya perbaikan untuk semua komoditas sayuran minor disarankan lebih diarahkan ke segmen konsumen yang pertama. Sementara itu, berdasarkan perbandingannya dengan komoditas padanan/substitusi (kacang jogo, bayam, zukini, dan kacang panjang), atribut produk yang perlu diperbaiki adalah atribut rasa enak dan gizi tinggi (kacang koro/roay), fungsi sebagai obat dan ketahanan simpan (labu siam), serta ketersediaan (kacang koro/roay, katuk, dan kecipir).ABSTRACT. Adiyoga, W., M. Ameriana, and T. A. Soetiarso. 2008. Market Segmentation and Perceptual Mapping of Product Attributes of Some Minor/under-utilized Vegetables. Consumer surveys were carried out in Sukasari and Lembang Subdistrict, Bandung, West Java from August to November 2004. This study was aimed to identify market segmentation and consumer’s perceptual mapping regarding product attributes of some minor (under-utilized) vegetables. Multi-stage cluster sampling was used to select 50 respondents who were proportionally and randomly drawn from those 2 subdistricts. Data were gathered through interviews by using a structured questionnaire. In this preliminary study, 4 minor vegetables were chosen; those were lima bean, stragooseberry, winged bean, and chayote. For the purpose of examining the product positioning of these 4 minor vegetables, 4 other vegetables that were considered as their substitute (bean, spinach, yard-long bean, and zucchini) were also involved. Product attributes examined were (a) high nutrient content, (b) medicinal purpose, (c) taste good/delicious, (d) long shelf-life, (e) price/expensive, and (f) availability. Results have identified 2 clusters or 2 market segments with different characteristics for each commodity. Number of cases/respondents in cluster 1 was consistently larger than that in cluster 2 for all commodities. Hence, the effort for improvements was suggested to be more focus to cluster 1 or consumer segment 1. Meanwhile, based on the comparison with their substitutes, some attributes that should be considered for improvement were taste and nutrient content (for lima bean), medicinal purpose, and shelf-life (for chayote), and availability (for lima bean, stragooseberry, and winged bean).

Abstract

Usahatani bawang merah telah dianggap menggunakan input bahan kimia sintetik terlalu tinggi, sehingga perlu dicari teknologi alternatif yang lebih ramah lingkungan dengan mengganti sebagian input kimia sintetik dengan bahan alami, seperti bahan organik. Untuk itu, diadakan kegiatan penelitian di Desa Kemukten, Kecamatan Kersana dari bulan Juni sampai dengan September 2003 menggunakan bawang merah varietas bangkok warso yang ditanam dengan jarak 17x17 cm. Tujuan penelitian ini adalah untuk mendapatkan macam pupuk organik dan dosis pupuk NPK untuk meningkatkan hasil sayuran dalam usahatani Leisa di dataran rendah. Rancangan percobaan menggunakan acak kelompok dengan tiga ulangan. Perlakuannya adalah kombinasi jenis pupuk organik (Oo = tanpa pupuk organik, O1= kompos ampas tebu dan O2 = bokasi jerami) dengan dosis pupuk NPK (Po = 0 kg/ha; P1 = 375 kg/ha; P2 = 750 kg/ha; P3 = 1.125 kg/ha, dan P4 = 1.500 kg/ha). Hasil percobaan menunjukkan bahwa pada tanaman yang tidak diberi bahan organik, penggunaan pupuk NPK (15-15-15) kadar 375 kg/ha sudah meningkatkan bobot basah dan bobot kering bawang merah secara nyata. Pada tanaman yang diberi bahan organik ampas tebu, pemupukan NPK (15-15-15) dosis 375 kg/ha sudah memberikan kenaikan hasil bawang merah baik bobot basah maupun bobot kering secara nyata. Sedang penggunaan bahan organik bokasi jerami dengan pupuk NPK (15-15-15) dosis 375 kg/ha hanya meningkatkan bobot basah hasil bawang merah secara nyata.Optimization of vegetable production input in lowland under LEISA system. Production of shallot has been considered to use high chemical synthetic input, so there is a need to look for an alternative technology which is more environmentally safe by replacing some chemicals input with natural product such as organic matters. The experiment has been conducted in Kemukten, Kersana, Brebes from June up to September 2003 by using shallot variety bangkok warso that was planted at planting distance of 17x17 cm. The objective of this experiment was to find out kind of organic manure and dosage of NPK to increase yield of shallot under LEI SA system. The experimental arranged in a randomized complete block design with three replications. The treatments were the combination between kind of organic matters without organic matter, sugarcane waste, and fermented rice straw) with dosages of NPK (0 kg/ha; 375 kg/ha; 750 kg/ha; 1,125 kg/ha; and 1,500 kg/ha). The results showed that shallot plantation without organic matters combined with 375 kg/ha NPK (15-15-15) could improve fresh and dry crops weight significantly. The application of sugarcane waste in combination with 375 kg/ha NPK (15-15-15), significantly increased fresh and dry weight of the harvested crops, while application of fermented rice straw organic matters in combination with 375 kg/ha NPK (15-15-15) just improved the yield in term of fresh crops weight significantly.

Abstract

ABSTRAK. Data dasar status hara khususnya P dan K di sentra produksi tanaman sayuran khususnya di dataran rendah lahan kering belum tersedia, sedangkan data tersebut sangat diperlukan sebagai dasar untuk menentukan rekomendasi penggunaan pupuk. Selama ini rekomendasi penggunaan pupuk diperoleh dari percobaan dosis pupuk dan bukan didasarkan pada analisis hara tanah yang bersangkutan dan respons tanaman terhadap penggunaan pupuk sehingga hasil yang diperoleh tidak komprehensif. Informasi status hara P dan K pada sayuran diperoleh dengan membuat peta sebaran status hara P dan K pada beberapa lokasi. Untuk tahap awal, data status hara P dan K tersebut dihimpun dalam peta semidetail dengan skala 1:100.000 di mana setiap cm2 unit peta mewakili areal seluas 25 ha dengan jarak observasi di lapangan setiap 500 m.Penelitian dilaksanakan di Kabupaten Bogor, Jawa Barat dari bulan Juli sampai September 2003, menggunakan metode survei. Tujuan penelitian adalah (i) membuat peta status hara P dan K lahan dengan skala 1:100.000 dan (ii) menyediakan data sebaran status hara P dan K di sentra produksi sayuran dataran rendah sebagai informasi dasar dalam pembuatan rekomendasi pupuk P dan K. Hasil pemetaan menunjukkan bahwa luas lahan berdasarkan peta status hara P seluas 1.365,03 ha termasuk kategori sangat rendah, 3.395,37 ha rendah, 21.248,71 ha sedang, dan 13.978,87 ha tinggi, sedangkan peta status hara K adalah 6.337,79 ha termasuk kategori sangat rendah, 12.768,03 ha rendah, 17.243,78 ha sedang, dan 3.638,39 ha tinggi.ABSTRACT. Hilman, Y., H. Sutapradja, R. Rosliani, and Y. Suryono. 2008. The Status of Phosphorus and Potassium Nutrient at Production Centre of Lowland Vegetables.Database of nutrient status of P and K in vegetable production area especially in dry lowland was not available yet, while these data was highly needed as a base for determining recommended dosage for fertilization. Until now, fertilization recommendation on vegetable was merely obtained from fertilizer dose experiment and did not rely on the soil nutrient status and crop response to fertilizer used, so that the results obtained from that experiment was not comprehensive. The study on the status of phosphorus and potassium nutrient in the lowland vegetables was conducted at Bogor, West Java from July to September 2003 using survey method. Information on the nutrient status of P and K in vegetable growing areas in this study can be obtained by making map of P and K distribution. For the first step, information of these P and K status was obtained from semi-detail map at the scale of 1:100.000 where each cm2 of map unit represented the area of 25 ha with the field observation distance of 500 m. The objective of this study was (i) to make the map of P and K nutrient status in lowland vegetable production areas at the scale of 1: 100.000 and (ii) to survey data of P and K nutrient status in lowland vegetable areas as database information in making recommendation of P and K fertilization.Results of mapping indicated that land area based on P nutritional status was categorized as follows:1,365.03 ha very low; 3,395.37 ha low; 21,248.71 ha moderate, and 13,978.87 ha high, while for K nutritional status of 6,337.79 ha very low; 12,768.03 ha low; 17,243.78 ha moderate; and 3,638.39 ha high.

Abstract

ABSTRAK. Percobaan dilaksanakan di Kebun Percobaan Wera, Subang, dari bulan Mei sampai November 2005, dengan tujuan mendapatkan dosis dan formula pupuk tablet dan pupuk tepung PML-Agro yang tepat untuk meningkatkan hasil cabai merah dan efisiensi aplikasi unsur hara tanaman. Percobaan menggunakan rancangan petak terpisah dengan 3 ulangan. Perlakuan terdiri dari bentuk pupuk PML-Agro sebagai petak utama, sedangkan dosis dan formula pupuk PML-Agro dan pupuk tunggal sebagai anak petak. Hasil percobaan menunjukkan bahwa perlakuan pupuk PML-Agro 2 (600 kg/ha) dan kombinasi pupuk PML-Agro 1 (150 kg/ha)+PML-Agro 3 (150 kg/ha) menghasilkan buah cabai merah tertinggi, meskipun tidak berbeda nyata dengan kombinasi pupuk tunggal (Urea, ZA, TSP, KCl, dan dolomit). Peningkatan hasil dari kedua pupuk tersebut masing-masing sebesar 16,38 dan 11,41%. Penggunaan pupuk tablet dan tepung tidak berpengaruh terhadap pertumbuhan dan hasil tanaman cabai merah. Pemberian pupuk PML-Agro 1 (150 kg/ha)+PML-Agro 3 (150 kg/ha) baik dalam bentuk tablet maupun tepung dapat dianjurkan, karena lebih efisien dari penggunaan pupuk PML-Agro 2 (600 kg/ha) maupun pupuk tunggal (Urea, ZA, TSP, KCl, dan dolomit) dengan efisiensi penggunaan hara makro primer 25% lebih rendah daripada pupuk tunggal. Teknologi pemupukan yang dihasilkan ini lebih menguntungkan karena penggunaan pupuk yang efisien dan daya hasil meningkat.ABSTRACT. Sutapradja, H. 2008. Application of PML-Agro Complete Multinutrient Fertilizer on Growth and Yield of Hot Pepper.This experiment was conducted at Wera, Subang Experimental Garden, started from May to November 2005, to find out the proper dosage and formulation of tablet and powder fertilizers to increase yield of hot pepper and nutrient efficiency. The experiment was arranged in a split plot design with 3 replications. The treatment consisted of PML-Agro fertilizer as main plot, and dosage formulation of PML-Agro fertilizer and combination of single fertilizers as subplot. The results showed that PML-Agro 2 fertilizer (600 kg/ha) and combination of PML-Agro 1 fertilizer (150 kg/ha)+PML-Agro 3 fertilizer (150 kg/ha) produced highest yield of hot pepper, although both treatments were not significanly different from the combination of single fertilizers (Urea, ZA, TSP, KCl, and dolomit). Yield increased due to the application of both fertilizers were 16.38% and 11.41% respectively. Application of tablet and powder fertilizers did not significantly affect the growth and yield of hot pepper. Combination of PML-Agro 1 fertilizers (150 kg/ha)+PML-Agro 3 fertilizer (150 kg/ha) in tablet and powder forms seemed to be more applicable for farmers, since they were more efficient than those of PML-Agro 2 (600 kg/ha) fertilizer and combination of single fertilizers (Urea, ZA, TSP, KCl, and dolomit) with efficiency of macro nutrient application about 25% lower than that of single fertilizer application. The use of PML-Agro fertilizer was more profitable due to its efficiency and yield improvement.

Abstract

ABSTRAK. Pada tahun 2008 Balai Penelitian Tanaman Hias telah melepas varietas Candilongi dengan karakter bungategak, beraroma agak wangi, dan tabung bunga relatif panjang. Perbaikan genetik telah dilakukan selama April 2008sampai dengan Agustus 2010 untuk menghasilkan varietas unggul baru yang disukai konsumen. Tujuan utama programpemuliaan lili ialah memperpendek ukuran tabung bunga. Perakitan varietas lili dimulai dengan menyilangkan aksesikerk lili LC-33 (longiflorum-candidum) dan Casablanca (hibrida oriental). Penyilangan menghasilkan populasi F1yang selanjutnya dipelihara di dalam rumah kaca hingga berbunga. Seleksi positif dilakukan dengan menggunakankriteria ukuran tabung bunga yang lebih pendek daripada Candilongi. Selanjutnya individu terpilih diperbanyak secaraterbatas dan dievaluasi. Penelitian menggunakan rancangan acak kelompok dengan enam perlakuan dan tiga ulangan.Perlakuan terdiri atas lima klon terpilih dan varietas Candilongi sebagai pembanding. Hasil penelitian menunjukkantiga dari lima klon terpilih memiliki keragaan bunga yang lebih baik daripada varietas Candilongi. Oleh karena itu,tiga klon tersebut sangat potensial untuk dilepas dan dikembangkan secara komersial. Hanya satu klon yang memilikikarakter unik seperti bunga tegak berbentuk lonceng, tabung bunga pendek, dan beraroma sangat wangi.ABSTRACT. Sanjaya, L. 2010. Assembly of Lilium Varieties Which Have Erect Flower, Aromatic Fragrance,and Short Floret Tube. In 2008 Indonesian Ornamental Crop Research Institute released a new superior variety ofLilium cv. Candilongi possessing main flower characteristics i.e., erect flower, moderately strong aromatic fragrance,and moderately long floret tube. Genetic improvement of the new superior variety had been conducted continuouslysince April 2008 to Agustus 2010 to produce new varieties according to consumer’s preferences. The main issueof this breeding program was to shorter its floret tube. To achieve the breeding goal, crosses were made betweenlily accession No. LC-33 (longiflorum-candidum) and cv. Casablanca (oriental hybrid). The crosses produced F1population that were all being maintained intensively in the greenhouse till flowering. Using criterium of shorterfloret tube than Candilongi, positive selection was conducted.
