The stages of seeding paddy rice seeds before planting require more time, cost, and labor than seeds that are planted directly without the seeding stage. Pelleting is an alternative technology in planting small-sized rice seeds without going through the seeding stage. This study aims to determine the effect of pelleting on the germination of paddy rice seeds. This experiment is a non-factorial experiment consisting of 9 treatments and repeated 3 times in a Randomized Block Design (RBD). The nine treatments were: (P0) No pellets, (P1) Clay + CMC + Dolomite 4 g, (P2) Clay + CMC + Dolomite 12 g, (P3) Clay + AG + Chalk 4 g, (P4) Clay + AG + Chalk 12 g, (P5) Clay + CMC + Mycorrhizae, (P6) Clay + AG + Mycorrhizae, (P7) Clay + CMC + Trichoderma, (P8) Clay + AG + Trichoderma. The data obtained were analyzed for variance and performed with the Honest Significant Difference (HSD)test using the R-studio statistical program. The results showed that the pelleting technique did not inhibit rice seed germination as indicated by the variables of germination, time of emergence of plumules, speed of germination, vigor index, normal germination root length, normal germination colept length, normal germination wet weight, normal germination dry weight. This means that clay can be used as a filler, Carboxyl methyl cellulose (CMC) and Arabic gum (AG) as an adhesive and microorganisms (mycorrhizae and trichoderma) can be added as seed pellet material

Acid soils in Lampung contain a lot of Al, Fe, and Mn, which inhibit soybean growth and production. The study of seed germination is important since plant growth begins with seeds. The study aimed to determine (1) the viability of various local soybean seeds: Anjasmoro, Grobogan, Dena-1, and Devon-1 on Al, Fe, and Mn heavy metal media and (2) the highest effect of dissolved metals among Al, Fe, and Mn on the viability of soybean seeds. The research was conducted at the Laboratory of Seed and Plant Breeding, Faculty of Agriculture, the University of Lampung from November 2019 to March 2020. The research applied a randomized complete block design (RCBD) with three replications and the data were averaged and presented as bar charts and standard deviation. The experiments were evaluated based on germination variables including germination capacity, average seed germination time, primary root length of normal germination, and dry weight of normal seedlings.The results showed that Grobogan and Anjasmoro varieties had high resistance to dissolved metals Al, Fe, and Mn, followed by Dena-1 varieties while Devon-1 was the most susceptible. The fourth day of germination showed that Fe caused the highest damage to the seeds, followed by Mn and finally Al. Interestingly, on the fifth day of germination, dissolved metal Mn had the highest toxicity effect, followed by Fe and Al.

Pemilihan benih bermutu sangat tergantung pada umur benih karena berpengaruh terhadap peningkatan hasil kedelai. Pengujian viabilitas dan vigor benih perlu dilakukan untuk mengetahui mutu benih kedelai. Penelitian ini bertujuan untuk mengetahui perbedaan pola perkecambahan, viabilitas dan vigor antara benih kedelai baru dan lama. Penelitian ini dilaksanakan di Laboratorium Benih dan Pemuliaan Tanaman, Fakultas Pertanian Universitas Lampung. Penelitian ini menggunakan perlakuan faktor tunggal dengan umur simpan 3 bulan (benih kedelai baru) dan 14 bulan (benih kedelai lama) dalam rancangan acak lengkap (RAL), serta setiap satuan percobaan diulang sebanyak 10 kali. Data yang dihasilkan kemudian diuji keseragaman menggunakan uji Barlett. Perbedaan antarperlakuan dilakukan uji t-student. Hasil penelitian menunjukkan bahwa (1) Benih kedelai lama berkecambah lebih lambat dibandingkan benih kedelai baru, berdasarkan hasil pola perkecambahan, (2) Benih kedelai baru menunjukkan viabilitas yang lebih tinggi dengan kecambah normal 94% dan vigor (kecepatan berkecambah 38,63%; dan indeks vigor 92,8), sedangkan pada benih lama menghasilkan viabilitas kecambah normal 81,4% dan vigor (kecepatan berkecambah 21%, dan indeks vigor 79,2).

Agricultural are significant sources of N2O emission. Lampung, Indonesia is an area dominated by agriculture including crops that emit N2O on their cultivation practices especially the fertilizers: paddy and vegetables. Last census in 2015 recorded that paddy fields were 1.321.120 ha and vegetables 99,284 ha with fertilizers recommendations were 200 kg/ha urea (without organic materials) and 150 kg/ha urea (if added with 2 tons/ha manure). This study aimed to estimate and predict N2O emissions based on the paddy field area using IPCC 2006 model. The IPCC model was applied to the paddy field data 1993 to 2012 from the Indonesian Ministry of Agriculture to estimate the N2O emission and then using Box Jenkins model to predict the emission for following years. The results showed that the prediction of N2O emission on the following years would be in the range of 0.282- 0.451Gg/year using only synthetic fertilizer and if added with organic fertilizers would be 5,846-9,359 Gg/year. These results were lower compared to some countries; however, this result was not implied that fertilizer recommendations in Lampung were safe since the results came from default numbers of the model. More researches should be conducted that local emission factors would be available that fertilizer recommendation could be evaluated.

Universities have three complementary missions, namely research, teaching, and community services. The Lampung University community services has responsibilities to the surround communities with being active roles in educating people, doing the strategic plans of the university, implementing and disseminating various university research results. Sekincau is a region in West Lampung with a great potential for horticulture productions, however, until recently, Lampung depends on West Java for supplying of horticulture productions. Some community programs had been done consistently in this area by Agronomy faculties of Lampung University with the local agriculture extension and farmers groups. The activities included introducing and developing good quality seeds of potato and baby beans seeds until certified for progeny of basic seed, intercropping of sorghum and baby beans, introducing internet applications useful for farmers and built a start-up particularly for young farmers. The method was “training and visit” which for regions where the level of development is still very low, instructing farmers what to do was probably more appropriate. This paper evaluated university roles in disseminating innovation to farmers. In general, it can be concluded that community development and services would only effective if continually conducted by the same group and focused on certain chosen area.
