Tomato; varieties; Lentana F1; Permata; compost; peat; manure
This study was aimed at determining type of organic material suitable for the growth and yield of two varieties of tomatoes and the interaction between the two factors. This experiment was conducted at the experimental field of the Agriculture Faculty, Syiah Kuala University, Darussalam, Banda Aceh. The experiment was arranged in a randomized complete block design, 4 x 2 with three replications. There were two factors investigated: organic material consisting 4 levels (control, manure, compost peat, and compost), varieties consisting two levels (Permata and Lentana F1). Variables observed were height and stem diameter, fruit weight per plant, number of fruits per plant, number of bunches per plant, number of fruits per bunch, average weight per fruit and yield potential. The results showed that the type of organic material highly significantly affected plant height and stem diameter at the ages of 30 and 45 days after planting, fruit weight per plant, number of fruits per plant, and significantly affected plant height at the age of 15 HST but did not significantly affect the number of bunches per plant, number of fruits per bunch, average weight per fruit and yield potential. Growth and yield were better at manure compared to compost, peat compost, and control. Varieties significantly affected stem diameter at the age of 15, 30 and 45 days after planting, fruit weight per plant, number of fruits per plant, number of bunches per plant, number of fruits per bunch, average weight per fruit and potential results. Growth and yield were better found in varieties Permata. There were significant interactions between types of organic materials and varieties in all observed variables on growth and yield of tomato.

PENGARUH JENIS DAN PERSENTASE SUPERPLASTICIZER TERHADAP KUAT TARIK LENTUR BETON MUTU TINGGI
Beton merupakan pilihan utama yang banyak digunakan dalam konstruksi di dunia sebagai elemen struktur pada bangunan gedung dan bangunan sipil lainnya. Hal ini disebabkan karena pengerjaannya relatif mudah dan dapat dibentuk sesuai dengan kebutuhan maupun keinginan penggunanya. Penggunaan nilai FAS yang rendah dan penambahan bahan additive seperti silica fume telah menjadi hal yang lazim dilaksanakan untuk memodifikasi mikrostruktur dari semen dan meningkatkan kekuatannya. Efek dari penggunaan FAS yang rendah dan penambahan silica fume ke dalam campuran beton menyebabkan kesulitan dalam proses pengerjaan dan pemadatan (workability rendah), sehingga diperlukan adanya penambahan bahan admixture lain berupa superplasticizer untuk meningkatkan daya kerjanya. Ketepatan dosis penambahan superplasticizer perlu dibuktikan dengan membuat campuran percobaan (trial mixes). Penelitian ini dilakukan dengan tujuan untuk mengetahui kuat tarik lentur beton menggunakan superplasticizer yang berbeda dengan persentase 1,0%; 1,5% dan 2,0% dan silica fume sebanyak 8% dari total berat semen. Benda uji yang digunakan untuk pengujian tarik lentur berbentuk balok berukuran 15 cm x 15 cm x 60 cm. Dalam penelitian ini nilai FAS yang digunakan yaitu 0,3. Diameter maksimum agregat yang digunakan 16 mm. Superplasticizer yang digunakan terdiri dari dua macam yaitu Sikament LN dan Sikament NN. Jumlah benda uji untuk masing - masing variabel 3 buah benda uji, sehingga jumlah total benda uji pada penelitian ini sebanyak 36 buah dengan metode perawatan direndam dalam air. Pengujian dilakukan pada umur 7 hari dan 28 hari. Hasil penelitian ini menunjukkan bahwa penggunaan Sikament NN lebih baik dibandingkan dengan Sikament LN. Kuat tarik lentur tertinggi untuk umur 28 hari sebesar 4,532 MPa persentase Sikament NN 1,5%, sedangkan kuat tarik lentur terendah sebesar 4,234 MPa dengan persentase Sikament NN 2,0%. Untuk Sikament LN, kuat tarik lentur tertinggi sebesar 4,244 MPa dengan persentase 1,0%, sedangkan kuat tarik lentur terendah sebesar 3,558 MPa dengan persentase 2,0%. Dari hasil penelitian ini dapat disimpulkan penggunaan Sikament NN lebih baik dari pada penggunaan Sikament LN.Kata Kunci :Beton Mutu Tinggi , Superplasticizer, Silica Fume, Kuat Tarik Lentur.

PENGARUH JENIS KAKAO DAN KOMBINASI ZAT PENGATUR TUMBUH TERHADAP INDUKSI EMBRIO SOMATIK SECARA IN VITRO
kinetin; 2,4-D; cacao; callus; somatic embryo
In an effort to increase the productivity of cocoa in Aceh, the government has carried out a cocoa plantation revitalization program for plants aged 25-30 years. The revitalization effort was constrained by the unavailability of quality seedlings. Alternatively, cocoa seedlings can be made available through vegetative propagations or through tissue culture techniques. Based on those facts, we have studied the inducing of callus and somatic embryos of cacao clones that were adaptive and highly productive in Aceh. The experiment was arranged in a completely randomized design, consisted of two factors. The first factor was the cacao genotype, having red and green fruits skin. The second factor consisted of six combinations of growth regulators 2,4-D and kinetin. The results showed that genotype of explants origin from cocoa red flowers responded very well in the formation of callus and somatic embryo formation. There was a significant interaction between genotype and growth regulator combinations on the explants in the number of somatic embryos formed. The best combination of concentrations growth regulator in response to somatic embryo in SCG (Secondary Callus Growth) medium was 3 mgL-1 2,4 D and 1 mgL-1 kinetin for explants from cocoa red flowers, and 1 mgL-1 2,4 D and 0 mgL-1 kinetin for explants origin from cacao green flowers.
