Abstract

       Performances of Shallot Plant (Allium Ascalonicum L.) In Various Dosage of KCl Fertilizer In Swampy Land. Swampy land utilization for vegetable crops is a strategic choice for developing agriculture because swampy land has great potential and prospect as a national food source to offset the shrinking of productive land on the island of Java which is converted to the development of non-agricultural sectors. However, the utilization of swampy land requires proper cultivation techniques such as site-specific fertilization including the application of potassium that is an essential nutrient for shallots. Adequate application of potassium fertilizer in plants known can improve crop resistance to pests, increase yields (seeds or tubers), and also improve tuber quality. The aims of this study was to get the dose of KCL fertilizer which provided the highest weight of shallot tubers. The study was conducted in June 2016 - November 2016 in Hulu Sungai Tengah District, South Kalimantan with the type of swampy land, using the Biru Lancor variety and Randomized Block Design with 8 replications. Parameters observed were the percentage of grew plants, wet weight per tuber, number of tubers, diameter of tubers and production. The results showed the use of KCL fertilizer at a dose of 300 kg ha-1 produced the highest yields and dry weight of shallots.    Pemanfaatan lahan rawa lebak untuk tanaman sayuran merupakan pilihan yang strategis karena lahan rawa lebak mempunyai potensi dan prospek besar sebagai sumber pangan nasional untuk mengimbangi penciutan lahan produktif di pulau Jawa yang dialihfungsikan untuk pembangunan sektor non pertanian. Namun pemanfaatan lahan rawa lebak memerlukan teknik budidaya yang tepat seperti pemupukan spesifik lokasi termasuk pemberian kalium yang merupakan hara penting bagi bawang merah. Pemberian pupuk kalium yang cukup pada tanaman telah diketahui dapat meningkatkan ketahanan tanaman terhadap hama penyakit, hasil panen (biji atau umbi), dan juga memperbaiki kualitas umbi.  Penelitian ini bertujuan untuk mendapatkan dosis pupuk KCL yang memberikan bobot umbi bawang merah paling tinggi. Penelitian  dilaksanakan pada bulan Juni 2016 – Nopember 2016 di Kabupaten Hulu Sungai Tengah, Kalimantan Selatan dengan tipe lahan rawa lebak, menggunakan varietas Biru Lancor  dan Rancangan Acak Kelompok dengan ulangan 8 kali. Parameter yang diamati meliputi persentase tanaman yang tumbuh, bobot basah per umbi, jumlah umbi, diameter umbi, dan produksi. Hasil menunjukkan penggunaan pupuk KCL dengan dosis 300 kg ha-1 di menghasilkan produksi dan bobot kering bawang merah paling tinggi.

Abstract

Capacity and Capability Differences on Rice and Shallot Farmers and the Impact on the Farming Productivity. During the last two decades there has been no stepping up in the production of rice and shallots farming. This is caused by low use of research innovation as well as the slow delivery of innovations to users. On the other hand, most of farmers' perceptions on extension workers are not entirely positive. The extension activities have not answered farmers need, and low impact on improving farmers' capacity and capability. The study objectives were (1) to analyze the differences on rice and shallot farmers capacity and capability, (2) to analyze the factors affected the farmers capacity and capability, and (3) to formulate a strategic approach to increase farmers capacity, capability and their farm productivity. The research was carried out through a structured survey of rice farmers in Subang and Boyolali Districts (n=270), and shallot farmers in Cirebon, Brebes, and Grobogan districts (n=249), from May to December 2018. The results of study showed that there was differences in capacity dan capability between rice farmers and shallot farmers affecting productivity among farmers and production gaps at the farm level. The use of innovation as a result of extension activities, had a high opportunity to increase in farmers' production and income. On shallots farmers the The productivity difference among farmers on shallot commodity was relatively high, because of the gap in the application of innovation in farming activities, so that the increase in capability did not directly affect on the production and income of farmers.

Abstract

ABSTRACT Arrangement of Guava Flowering (Psidium guajava L.) ‘Krystal’ through the Application of Different Strangulation Times. The seasonal production of guava (Psidium guajava) requires flowering manipulation technique such strangulation in order to be available throughout the years. This study aimed to explain the relationship between strangulation time, the period of flowering and harvesting of guava cv 'Krystal'. The experiment was conducted from February to December 2017, in Cikabayan experimental garden of IPB University, Bogor, Indonesia. The experiment used a completely randomized design with single factor, i.e strangulation times that consisted of control (no strangulation), strangulation in March, in April and in May. The results showed that strangulation treatment was able to accelerate the emergence of flowers and increase the number of generative shoots, the number of flowers per tree and the number of fruits harvested. The increase of flowering response on strangulated trees was supported by a higher leaf C/N compared to control, which is related to the low leaf N content in strangulation treatments. The strangulation treatment could accelerate the time of flower emergence six days earlier than control.  Keywords: guava, C/N, flowering induction, ringing, seasonal production ABSTRAK Produksi buah jambu biji (Psidium guajava) yang bersifat musiman memerlukan teknik pengaturan pembungaan agar dapat tersedia sepanjang tahun. Penelitian ini bertujuan untuk menjelaskan keterkaitan antara waktu strangulasi dengan pola pembungaan dan panen buah jambu biji ‘Kristal’.

Abstract

ABSTRACT                 Assessment of Fertilization Technology Package Shallot Using Mini Bulb in Cirebon District. One of the main problems on the increasing shallot production is the limitation of high-quality plant materials. The use of mini bulbs on their cultivation is expected as one of the solutions.  The cultivation using these materials is almost the same as conventional ones.  Some benefits would be obtained when using mini bulbs as seeds, it is more efficient because it does not require a lot of its volume and the resulting production can be higher.  Generally, shallot cultivation at many farmer levels is less profitable caused by the use of excessive chemical fertilizers, so it is necessary to have proper fertilization studies. The purpose of this assessment was to compare the application of technology packages based on Balitsa fertilization recommendation with the farmer’s one using mini bulbs as plant materials on Bima Brebes shallot cultivation. The research was carried out in Cukang Akar Village, Pabedilan Sub District, Cirebon District from August 2014 to January 2015. Parameters observed were plant height, number of tillers, weight, diameter, and length of bulbs, total bulbs per plant and production as well as production costs, profits and B/C. Plant growth data were analyzed descriptively and further tested using the t-test at the 5% confidence level. The results of the assessment showed that there was no significant difference between both treatments, the technology packages and the farmers were one on all parameters, but the application of technology packages was more profitable 114.240 IDR per hectare, with B/C value was 1.13.  Keywords: shallot, fertilizer, mini bulb ABSTRAK Salah satu kendala utama yang dihadapi dalam usaha peningkatan produksi bawang merah adalah terbatasnya ketersediaan benih bermutu. Penggunaan benih umbi mini diharapkan menjadi salah satu solusinya. Budidaya bawang merah dengan menggunakan benih asal umbi mini hampir sama dengan umbi konvensional. Penggunaan umbi mini mempunyai kelebihan yaitu lebih efisien karena tidak memerlukan volume benih yang banyak dan produksi yang dihasilkan dapat lebih tinggi. Secara umum, budidaya bawang merah di tingkat petani banyak yang kurang menguntungkan, salah satunya disebabkan penggunaan pupuk kimia berlebihan, sehingga perlu pengkajian pemupukan yang tepat. Tujuan pengkajian adalah membandingkan penggunaan paket teknologi berdasarkan teknologi rekomendasi pemupukan Balitsa dengan cara petani pada budidaya bawang merah dengan menggunakan benih umbi mini. Pengkajian dilaksanakan di Desa Cukang Akar, Kecamatan Pabedilan, Kabupaten Cirebon  pada bulan Agustus 2014–Januari 2015. Varietas bawang merah yang digunakan adalah Bima Brebes. Parameter yang diamati yaitu tinggi tanaman, jumlah anakan, berat umbi, diameter umbi, panjang umbi, jumlah umbi per tanaman dan produksi serta biaya produksi, keuntungan dan B/C. Data pertumbuhan tanaman dianalisis secara deskriptif dan diuji lanjut t-test pada taraf kepercayaan 5%. Hasil pengkajian menunjukan bahwa tidak terdapat perbedaan yang nyata antara perlakuan paket teknologi dan cara petani pada semua parameter, namun aplikasi paket teknologi lebih menguntungkan Rp. 114.240 per hektar, dengan nilai nisbah B/C 1,13. Implikasinya keuntungan yang diperoleh petani lebih tinggi.Kata kunci: bawang merah, pemupukan, umbi mini

Abstract

Feasibility and Perspective Analysis of Sagu Processing Development in South Sulawesi. Sago starch has an important role both as a staple food and a material for making various other processed food products. Sago processing can produce both wet sago and dried sago starch. The study was conducted to determine the feasibility of the sago processing business and its development perspective in Southeast Sulawesi. The study was conducted in South Konawe District in March - December 2017. Data were collected through field observations of the Biosagu Sejahtera Farmer Group in Matalamokula Village, North Moramo Sub District which has wet and dry sago production units. The data collected were the production capacity of wet sago and dry sago, the price of sago trees, the price of wet sago and dry sago, the production costs include labor costs, fuel costs, packaging costs as well as the costs of depreciation of tools and machinery. Data were analyzed using a profit equation. The results showed that the production of wet sago starch on a processing scale of 12 sago trees (1 production cycle) was feasible because it provided a profit of 7,314,000 IDR with Production-Break Even Point (PBEP) of 2,359 kg and Price BEP of 1,493 IDR and RCR value was 1.93. Likewise, dry sago production business was feasible with an RCR of 2.18; BEP from the production and price were 460 kg and 7,571 IDR respectively and provided profit of around 6,435,000 IDR. Thus the production of wet sago and dry sago can be alternative non-farm employment in rural areas. Perspective of sago processing in Southeast Sulawesi in the future is quite good due to the several supports such as availability of sago plantation area, the availability of human resources, the technology available as well as policies and regulations from the government. The demand for sago in the future will be influenced by the demand to substitute commodities that are still imported such as wheat and sugar as well as products that have a large domestic use, namely bioethanol. The development of sago in the future needs to respond to changes in demand by changing the management model with conventional management to modern technology. Tepung sagu memiliki peran penting baik sebagai bahan pangan pokok maupun sebagai bahan pembuatan berbagai produk olahan pangan lainnya. Pengolahan sagu dapat menghasilkan tepung sagu basah dan tepung sagu kering. Kajian dilakukan untuk mengetahui kelayakan usaha pengolahan sagu serta perspektif pengembangannya di Sulawesi Tenggara. Penelitian dilakukan di Kabupaten Konawe Selatan bulan Maret – Desember tahun 2017. Pengumpulan data dilakukan melalui observasi lapangan terhadap Kelompok Tani Biosagu Sejahtera Desa Matalamokula, Kecamatan Moramo Utara yang memiliki unit produksi sagu basah dan unit produksi sagu kering. Data yang dikumpulkan  adalah kapasitas produksi sagu basah dan sagu kering, harga pohon sagu, harga sagu basah dan sagu kering, biaya produksi meliputi biaya tenaga kerja, biaya bahan bakar, biaya kemasan serta biaya penyusutan alat dan mesin, analisis data dilakukan menggunakan persamaan keuntungan. Hasil penelitian menunjukkan bahwa usaha produksi tepung sagu basah pada skala pengolahan 12 pohon sagu (1 siklus produksi) layak diusahakan karena memberikan keuntungan sebesar Rp 7.314.000, dengan nilai Titik Impas Produksi (TIP) dan Titik Impas Harga (TIH) masing-masing 2.359 kg dan Rp 1.493 serta nilai RCR sebesar 1,93. Usaha produksi sagu kering layak dilakukan dengan nilai RCR sebesar 2,18; nilai TIP dan TIH masing-masing 460 kg dan Rp 7.571 serta memberikan keuntungan sebesar Rp 6.435.000. Usaha produksi sagu basah maupun sagu kering dapat menjadi alternatif lapangan kerja non farm di pedesaan. Perspektif pengolahan sagu di Sulawesi Tenggara ke depan cukup baik karena ditunjang ketersediaan areal pertanaman sagu cukup luas, ketersediaan sumberdaya manusia, teknologi hingga dukungan kebijakan dan regulasi. Permintaan sagu ke depan akan dihela oleh permintaan untuk mensubstitusi komoditas-komoditas yang selama ini masih diimpor seperti gandum dan gula maupun produk yang pemanfaatannya dalam negeri cukup besar yaitu bioetanol. Pengembangan sagu juga perlu merespon perubahan-perubahan permintaan tersebut dengan mengubah model pengelolaan dengan teknologi konvensional menjadi teknologi modern.
