Tanah pasiran merupakan lahan marjinal yang potensial untuk dijadikan sebagai lahan pertanian. Sifat fisika tanah pasiran merupakan salah satu faktor pembatas karena didominasi pori makro. Pengelolaan dengan aplikasi biochar berbahan baku dari limbah tanaman perkebunan pada tanah pasiran merupakan salah satu alternatif untuk memperbaiki kondisi fisika tanah sehingga dapat mendukung sebagai media tanam pembibitan tanaman tembakau (Nicotiana tabacum) Besuki Na-Oogst. Penelitian dilakukan pada bulan Maret-September 2017 bertempat di Laboratorium Konservasi dan Fisika Tanah, Laboratorium Kesuburan Tanah dan Green House Fakultas Pertanian Universitas Jember. Rancangan penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Faktorial yang terdiri atas 2 faktor yaitu faktor jenis biochar yang terdiri dari biochar limbah kulit kopi (B1), biochar limbah kulit kakao (B2), dan biochar biji karet (B3) dan faktor kedua adalah dosis biochar tersebut yaitu meliputi tanpa biochar/kontrol (D1), 12,5 g/kg tanah (D2), 25 g/kg tanah (D3) dan 37,5 g/kg tanah (D4). Hasil penelitian menunjukkan bahwa interaksi antara dosis biochar dengan taraf dosis yang berbeda memberikan pengaruh terhadap pH tanah, tinggi tanaman, panjang daun, lebar daun, luas permukaan daun, diameter batang, panjang akar, berat basah dan berat kering bibit tembakau besuki na-oogst. Setiap jenis biochar dan dosis biochar masing-masing memberikan pengaruh yang berbeda terhadap perbaikan sifat fisik tanah pasiran yaitu menurunkan nilai berat volume (BV), meningkatkan porositas, water holding capacity (WHC) dan pH tanah.Kombinasi perlakuan yang terbaik untuk pertumbuhan bibit tembakau besuki na-oogst adalah pada jenis biochar biji karet dengan dosis 25 g/kg tanah.

The purpose of this study was to examine the strategies for improving the quality standardization of Besuki Na-Oogst tobacco cultivation. Data sources were obtained from the results of in-depth interviews with Besuki Na-Oogst tobacco-related stakeholders. The analytical method used was the Analytical Hierarchy Process (AHP). The results of the study showed that the success of Besuki Na-Oogst tobacco cultivation governance as a quality and export-oriented product was not only determined by good cultivation techniques but also needed to be supported by institutional patterns from upstream to downstream, starting from on-farm to off-farm. Trade and marketing are being the main priorities in the development of tobacco quality. Some of the top rankings in alternative strategies are the role of formal institutions in marketing followed by management of quality standards, determination of selling prices and market expansion occupying the priorities of all alternatives in the development of tobacco quality. These results are in line with the important role of quality in export commodities in particular in which quality will affect competitive advantage and ultimately improve the welfare of farmers and other tobacco farming actors.

Abstrak. Proses pembibitan ubijalar haruslah didukung dengan ketersediaan hara yang cukup agar mampu meningkatkan produksi bibit yang berkualitas. Penambahan pupuk kandang ayam dan senyawa humat mampu meningkatkan kesuburan tanah. Penelitian ini bertujuan mengetahui pengaruh aplikasi pupuk kandang ayam dan senyawa humat terhadap jumlah bibit ubi jalar dan kesuburan tanah. Penelitian dilakukan menggunakan Rancangan Acak Kelompok Faktorial dengan dua faktor yaitu faktor pupuk kandang ayam dan faktor senyawa humat. Variabel pengamatan meliputi variabel kuantitas bibit dan variabel kesuburan tanah. Variabel kuantitas bibit adalah jumlah cabang dan jumlah bibit stek yang dihasilkan sedangkan variabel kesuburan tanah meliputi C-organik, N-total, P-tersedia dan K tersedia. Hasil penelitian menunjukkan kombinasi pupuk kandang ayam dan senyawa humat berpengaruh terhadap peningkatan jumlah cabang, jumlah bibit stek yang dihasilkan, N-Total, P-tersedia dan K-tersedia yang terdapat di dalam tanah. Pemberian faktor tunggal pupuk kandang berpengaruh terhadap peningkatan C-organik tanah. Kombinasi terbaik dalam meningkatkan kualitas bibit dan kesuburan tanah yaitu A2P3 (senyawa humat 200 ml dan pupuk kandang ayam 60 gram/tanaman/5 kg tanah). Abstract. The sweet potato seedling process must be supported by the availability of sufficient nutrients to increase the number of quality seed. The addition of manure and humic substance can increase soil fertility. This study aims to determine the effect of manure and humic substance applications on the quantity of sweet potato seeds and quality of soil fertility. The study was conducted using a factorial randomized block design with two factors: manure and humic substance. The observation variables included seed quantity and soil fertility. Seed quantity variable is the number of branches and number of cuttings produced while soil fertility variables include organic-C, total-N, available-P, and available- K. The results showed that the combination of manure and humic substance increased the number of branches, the number of cuttings produced, total- N, available-P, and available-K contained in the soil. A single factor of manure influences increase soil organic-C. The best combination for improving seed quality and soil fertility is A2P3 (200 ml humic substance and 60-gram manure/plant/5 kg of soil).

Triploid watermelon seeds are produced from the crossing between watermelon diploid as males and tetraploid watermelons as females. The success of triploid seed formation is influenced by the success of pollination determined by pollen viability which is characterized by the period of anthesis and peptic receptivity by the time of pollination. This experiment was conducted in Jember on 2018. The Factorial Randomized Block Design, 3x3 with three replications, was concucted to determine the effect of male anthesis period and pollination time on the success rate of seedless watermelon seed formation. The results showed that no significant interaction of the male anthesis period and the time of pollination effect. Pollens harvested during pre anthesis give the best pollination results. On the other hand, the best pollination can be done at 07.30 – 08.30 am Keywords: anthesis, pollination, seeds, seedless watermelon.

Seed cutting of sweet potato influenced by nutrient availability, especially nitrogen. Humic straw substances and cattle chicken manure fertilizer can increase the amount of nitrogen in the soil and also can improve the physical nature of soil. This study aimed to find out the influence of humic straw substances and cattle chicken manure fertilizer application toward the uptake of nitrogen nutrients for the seeds cutting quality of sweet potatoes. This research was conducted using factorial Randomized Block Design (RBD) with two factors, trere are humic straw subtances and cattle chiken manure. The variable observed was pH, C-Organic, N-Total of soil total length of plants, wet weight, dry weight, content of N-tissue, and N absorption. The result showed that a combination of humic straw substances and cattle chicken manure fertilizer influence to the increase of N-Total of soil, N-tissue, the uptake of N, the total length of plant, wet weight, and dry weight of the upper plants. The addition of a single factor of chicken manure fertilizer affects to the increase of pH and C-Organic of soil. Moreover, the best treatment combination in increasing the nitrogen uptake were A2P3 treatment (with 0.2% humic acid and 0.92 gram N of manure fertilizer). Furthermore, the best treatment combination in improving the number of seedlings cutting of sweet potatoes was A0P1 treatment (without humic acid and adding 0.46 gram N of manure fertilizer). Keywords: seed cutting of sweet potatoes, nitrogen, chiken cattle manure and humic subtances.
