The research on the application of fertilizer ABG (Bio Amazing Growth) and compost on the growth and yield of mustard greens (Brassica juncea L. Coss) has been carried out by using a randomized block design (RBD) consists of a two-factor factorial researched and 3 replications. ABG fertilizer treatments showed significant effect on the observed parameters such as plant height, leaf number and leaf area. But showed no real effect on the other parameters. Compost fertilizer treatments showed significant effect on all parameters except the parameter observations shoot root ratio shows no real effect. The interaction of fertilizer treatment and fertilizer Compost ABG showed significant effect on leaf area observed parameters, but the effect is not significant on the observation parameters plant height, number of leaves, root shoot ratio.Keywords: fertilizer ABG, compost, growth, production of green cabbage

The research of grafting methyl methacrylate onto Cyclized Natural Rubber has been carried out. Dicumyl Peroxide was used as a inisiator and temperature condition at 90oC with variation of time 1 and 2 hours. Grafting process was done with technique of reflux in a tree-neck flask with condenser and oil bath. Spectra analysis FTIR performed for determine the presence of grafted MMA on the backbone of CNR. The results showed that the product CNR-g-MMA was formed with the marked appearance of the absorption peak wave numbers at 1731 cm-1 (carbonyl group absorption) typical for carbonyl (C = O) of methyl methacrylate. The degree of grafting increased with the increasing time grafting.Keywords: grafting, cyclic natural rubber, mathylmetacrilate, dicumyl peroxide

Pada penelitian ini dilaporkan perubahan suhu transisi gelas produk pencangkokan anhidrida maleat pada karet alam siklis. Pencangkokan anhidrida maleat pada karet alam siklis dilakukan dalam fase leleh dengan penambahan komonomer divinil benzen di dalam pencampur internal suhu 185oC dan kecepatan rotor 85 rpm. Konsentrasi anhidrida maleat yang digunakan dalam proses pencangkokan adalah 16 phr, tanpa penambahan dan dengan penambahan komonomer divinil benzen dengan variasi: 0,5, 1 dan 2 mol rasio. Produk pencangkokan dikarakterisasi dengan Differential Scanning Calorimetry untuk mempelajari perubahan suhu transisi gelasnya. Berdasarkan analisis dan pengolahan data menggunakan software thermal analysis diperoleh bahwa semakin banyak penambahan komonomer divinil benzene maka suhu transisi gelasnya semakin tinggi, yaitu: 69,46oC, 69,51oC, 70,08oC dan 70,56oC.

Hutagaol Peatalun Village is one of Villages in Balige District Toba Samosis Subdidistrict. Hutagaol Peatalun village is one of the rice agriculture centre in Sumatera Utara.in developing agriculture, farmers have problems about rice disease, that’s blast disease,. To face the problem, farmer should be given solution to help farmer improving biopesticide that have active substance of trichoderma to resolve blast disease. To date, the impact of blast disease was decrease and loss farmer’s rice production. The activity was involving two agriculture group. This activity consist of socialization and practice to improve trichoderma biopesticide in corn media. The result of biopesticide was used by both of agriculture groups directly. This dedication activity succeed to increase farmer’s knowledge skill, and the point of view about biopesticide as the substitution of chemistry fungicide that always used by farmer’s.

This study aims to investigate the thermal properties of grafted products of maleic anhydride onto cyclized natural rubber. The grafting was carried out in the melt phase at an internal mixer of 150 oC and a rotor speed of 80 rpm. A total of 16 phr maleic anhydride was reacted with cyclized natural rubber in the present and absence of divinylbenzene comonomer with various mole ratios: 0.5, 1, and 2. The grafted products were characterized by the thermogravimetric method to investigate their thermal properties. Based on the results of the thermogravimetric analysis, it was shown that the sample increased its thermal stability. The sample decomposes at a higher temperature with the increasing mole ratio of divinylbenzene added. The grafted product with 16 phr maleic anhydride decomposed at 489.41 oC. Then, the graft product samples with the addition of 0.5, 1, and the 2-mole ratio of divinylbenzene comonomers decomposed at: 501.62 oC, 514.39 oC, and 520.82 oC, respectively.Keywords:Cyclized natural rubber, Divinylbenzene, Maleic anhydride, Thermamogravimetric

Pengabdian masyarakat adalah salah satu kegiatan yang sangat diharapkan untuk dapat terlaksana dengan baik, sebab dapat meningkatkan dan menambah ilmu pengetahuan serta keterampilan. Dalam kegiatan pengabdian masyarakat ini kita akan mengolah buah pare yang rasanya pahit menjadi cemilan di rumah Tahfiz Kalifah Aulia. Buah pare yang segar dicuci terlebih dahulu lalu dipotong potong dimana buah pare tersebut terlebih dahulu dibuang bijinya. Selanjutnya buah pare yang dipotong potong tersebut ditiriskan untuk diolah. Adapun bahan bumbu yang digunakan seperti kunyit, bawang merah, bawang putih, jahe, garam. Bahan ini digilng halus. Selanjutnya kita cairkan tepung dengan menggunakan santan kelapa serta ditambah telur, lalu bahan ini kita aduk dan campurannya dibuat merata. Selanjutnya bahan tepung serta bumbu dicampur. Proses tahap selanjutnya dilakukan proses penggorengan dengan memasukkan minyak goreng ke dalam kuali, selanjutnya buah pare dicampur dengan bahan bumbu, siap untuk digoreng. Setelah warnanya berubah coklat siap untuk diangkat, yang menunjukkan hasil gorengan telah matang. Diperoleh rasa renyah buah pare goreng dengan santan kelapa sebagai pelarut tepungnya sebesar 80% dan pelarut air untuk pelarut tepungnya rasa gurihnya diperoleh 60%.
