The purpose of this research is to improve the physical properties and fertility of soil to improve production of shallot. The research method used is a randomized block factorial design with 3 replication. The first factor was application of liquid fertilizer (N) consisting of 3 levels (N0: 0 cm3/L  water; N1: 1.5 cm3/L  water; N2: 3 cm3/L water). Second factor was cattle manure (A) consisting of 4 levels, namely: A0: 0 g; A1: 40 g cattle manure; A2: 80 g cattle manure; and A3: 120 g cattle manure. The results shown treatment with liquid fertilizer has a significant effect on plant height at weeks after planting (WAP). The study showed that treatment with liquid fertilizer has a significant effect on plant height, tuber weight per clump, and tuber weight per plot, but didn’t not have a significant effect on number of leaves and number of samplings of the shallot plants. Treatment with cattle manure has a significant effect on plant height, tuber weight per clump, tuber weight per plot, and tuber diameter, but does not have a significant effect on number of leaves and number of saplings of the shallot plants. It can be concluded that the higher the application of liquid fertilizer, up to 3 cm3/L , the higher the growth and production of shallot plants, and the higher the application of cattle manure, up to 120 g/plot the higher the growth and production of shallot plants. Keywords:  Plant height, Shallot, Soil Fertility, Tuber weight, Tuber size.

Tanaman manggis (Garcinia mangostana L) merupakan komuditas andalan eksport perlu dikembangkan secara komersial. Di Indonesia peluang untuk dikembangkan secara komersil sangat berpotensi, khususnya di Sumatera Barat rencana pengembangan manggis 6650 ha yang terealisasi baru 1354 ha, hal ini disebabkan langkanya bibit unggulan, teknologi perbanyakan terbatas. Perbanyakan secara in-vitro dapat menghasilkan 5-15 planlet biji-1 permasalahanya perakaran terbatas selalu mengalami kegagalan tumbuh waktu diaklimatisasi. Pemecahan masalahnya bibit di inokulasi dengan CMA berpengaruh positif terhadap perakaran yang kurang baik. Dan lebih mampan lagi apabila inokulasi CMA bersamaan dengan pemberian flavonoid. Flavonoid merupakan sinyal untuk stimulasi simbiosis CMA dengan bibit manggis. CMA dapat memperluas jelajahan akar sehingga dapat meningkat penyerapan hara, air dan mineral sehingga dapat memperbaiki pertumbuhan bibit manggis. Tujuan penelitian: Untuk mendapatkan jenis CMA yang dapat meningkatkan / memperbaiki pertumbuhahan akar bibit manggis, mendapatkan jenis flavonoid yang mampu meningkatkan pertumbuhan akar bibit manggis, mendapatkan flavonoid yang cocok untuk menstimulasi simbiosis berbagai jenis CMA. Penelitian merupakan percobaan pot dengan 2 taktor yaitu faktor utama Flavonoid (F0 = kontrol ; F1 = rutin ; F2 = Kuersetin ; F3 = Kuersitrin), faktor kedua CMA (C0 = kontrol ; C1 = G. margarita C2 = G. manihotis ; C3 = G. etunicatum), dan dirancang menurut Rancangan Acak Lengkap berpola faktorial. Hasil penelitian menunjukan pemberian CMA jenis G. manihotis dan G. etunicatum mampu meningkatka / memperbaiki pertumbuhan akar bibit manggis, juga flavonoid jenis kuersetin dan kuersitrin mampu meningkatkan pertumbuhan akar bibit manggis seperti , serapan P/tanaman, rasio tajuk akar. Pemberian flavonoid jenis kuersetin, kuersitrin cocok dengan CMA jenis G. manihotis dan G. etunicatum untuk meningkatkan pertumbuhan akar bibit manggis seperti infeksi akar, jumlah cabang primer akar. Pemberian CMA yang indigen dan flavonoid yang efektif untuk pertumbuhan bibit manggis yaitu G. manihotis, G. etunicatum dan kuersetin, kuersitrin

Capability of Cellulolytic Degradation (BSD) Bacteria (CDB) to Remodel Organic Waste intoCompost The purpose of this study was to obtain superior cellulolytic bacteria from acid soils as astarter for the degradation of organic waste in the city of Padang by testing the activity of cellulaseenzymes. The method used in the factorial method is the Cellulolytic Degradation Bacteria factorwith the Organic Waste of Padang City. This research was conducted at the Plant PhysiologyLaboratory and the Soil Science Laboratory, Faculty of Agriculture. The research activity was begunby isolating the bacteria from acid soil, followed by testing the enzyme activity of the specific mediumof carboxyl methylcellulose (CMC) medium. Factorial Complete Random Design Method. The firstfactor was selected 3 isolates of cellulolytic bacteria, the second-factor main market organic wasteat of Padang and was two treatments namely unstable sterile (A) and nonsterile (B). The researchresults obtained 6 isolates of cellulolytic bacteria with a clear zone index ≥ 2, namely Km25,Sr. 75, Jm, U-6, G-8, and Km 13, respectively 3.12; 3.04; 3.0; 2.04; 2.00, and 2.04, and used forcomposting organic waste 3 isolates of clear zone bacteria ≥ 3.0 isolates of KM25, Sr75, and JMrespectively 3.12; 3.04; 3.01. Non-sterile organic waste is better than sterile due to the non-sterile,there is the help of battery change from the trash. Conclusion The best composting material is notsterilized, and better bacteria decompose the waste combined with the three isolates KM25, SR75,and JM.

Background: The study aimed to obtain CDB with high degraded activities, determined growth curve, protein content, and cellulase maximum activity (exoglucanase and endoglucanase). Method:  The cellulose activity calculated according to Miller (1959), protein content was measured by Bradford method with bovine serum albumin (BSA) as a standardize protein. Result: Six isolates of CDB were found as potential degradation of organic waste (Km25, Sr75, Jm, U6, G8, and Km13). Growth curve, protein level, and protein maximum activity occurred on day-3. The largest diameter of clear zone of six isolates was Km25, Sr75, Jm, U6, G8, and Km13 (3.32, 3.31, 2.41, 2.36, 2.19, and 2.04 mm, respectively). Endoglucanase and exoglucanase maximum activity were 0.011-0.402 IU/mL and 0.0028-0.155 IU/mL, respectively. Conclusion: Six isolates showed high activities of cellulase with diameter of clear zone ≥ 2 cm (Km25, Sr75, Jm, U6, G8, and Km13). Growth maximum curve was on day-3. Highest endo- and exoglucanase activities were on day-3 (0.402 IU/mL and 0.155 IU/mL, respectively) in Jm isolate. Keywords: Identification, degradation, clear zones, cellulase.

Tujuan kegiatan ini adalah pengaplikasian tridarma perguruan tinggi dalam bentuk memberikan kontribusi kepada masyarakat terkait pengetahuan serta kefakaran dosen. Dalam hal ini melakukan sosialisasi budidaya tanaman azolla. Tempat pelaksanaan PKM ini di Pasantren Darussalam Guntur Batubara. Adapun materi yang disampaikan yaitu cara budidaya azolla, unsur kandungan yang dikandung serta menfaatnya. Diantara keungglan azolla yaitu pembudidayaannya sangat mudah. Kemudian Tumbuhan Azolla berpotensi besar sebagai pakan ternak karena memiliki kadar protein yang tinggi, asam amino esensial, vitamin (vitamin A, vitamin B12, Beta Carotene), serta mineral yang memadai. Tumbuhan Azolla memiliki kandungan protein kasar yang cukup tinggi yaitu sekitar 23 sampai 30 %. Serta memiliki kandungan lignin yang rendah sehingga mudah dicerna oleh ternak. Oleh karena itu tumbuhan Azolla cocok untuk dimanfaatkan sebagai campuran pakan ternak khususnya itik, ayam, kambing, sapi dan kelinci. Dengan kandungan gizi tersebut, menjadikan tumbuhan Azolla sebagai salah satu pengganti pakan yang paling ekonomis dan efisien untuk ternak. Dan dapat pula dijadikan sebagai pakan organik rutin untuk para peternak. Selain jauh lebih murah juga terbukti menjadi andalan para peternak modern untuk meningkatkan berat ternak dan meningkatkan produksi telur ayam dan itik.Kata Kunci : Budidaya; Azolla; Pakan ternak; Pupuk.
