<p>Youth is a valuable asset to the country. The success of the nation's development depends on the level of its youth participation. Phenomena declining the interest of youth in agriculture is a special concern for society and government. Amid in the youth interest in the agricultural sector work, there is a group of farmers who have an interest in agriculture, especially horticultural. The purpose of this research is to see the process of increasing youth interest in horticultural farming, a factor that affects youth interest and the process of forming rational youth choices related to increased interest in horticultural farming. Qualitative research with a descriptive exploratory approach was conducted in the village Kelor Karangmojo District in Gunungkidul Regency. Sampling techniques using purposive sampling techniques. As for the research, informant consists of the youths who belong in a group of horticultural farmer Youth, non-village youth groups and village devices. Data is collected by observing, post conducting interviews and documentation. To test the data validity using source triangulation. Data analysis techniques use interactive models of Miles and Huberman with the rational choice theory of James S. Coleman.</p><p>The results showed the process of increasing youth interest through: increased youth involvement in horticultural farms that are differentiated into direct involvement and supporting involvement about concerning frequency, long farmed and The youth-owned land area;  Increased members of Horticulture Farmer Youth Group; Raising horticultural farmland; and increased youth innovations in horticultural farming.

In maximizing the efforts of youth conduct collective behavior that is by forming a group of agriculture that has access to human resources and capital resources that can overcome the limitations of youth actors of individuals in activities Horticultural farming.</p>

Pembangunan infrastruktur akan terus meningkat seiring dengan meningkatnya jumlah penduduk. Beton sebagai bahan konstruksi yang umum digunakan dituntut memiliki kualitas yang tinggi, oleh karena itu, pada penelitian ini kami melakukan pengujian terhadap beton bubuk reaktif dengan <em>silica fume</em> 15% sebagai substitusi parsial semen dan variasi komposisi pasir kuarsa sebesar 0%, 15%, 20%, 25%, 30%, 35%, dan 40%. Beton bubuk reaktif menghilangkan agregat kasar dalam campurannya dan menggantikannya dengan agregat halus sehingga mampu meningkatkan homogenitas campuran beton dan menghasilkan beton mutu tinggi. Penelitian terhadap nilai kuat tarik belah menggunakan metode eksperimental dengan total benda uji 21 buah. Benda uji untuk mendapatkan nilai kuat tarik belah berbentuk silinder, tinggi 30 cm, diameter 15 cm, yang telah mencapai umur 28 hari, dan diuji menggunakan mesin CTM (<em>compression testing machine)</em>. Hasil pengujian kuat tarik belah dengan variasi pasir kuarsa 0%; 15%; 20%; 25%; 30%; 35%; dan 40%, memiliki nilai berturut-turut sebesar 33,91 MPa; 4,34 MPa; 4,45 MPa; 4,81 MPa; 5,07 MPa; 4,93 MPa; dan 4,69 MPa.

<p>Indoensia is an agricultural country, that agricutural sector hold such important role in the whole national economical aspects. Agricultural lands hold important role in the peasant’s productivity. Agricultural sector in Indonesia experienced high density of labors, meanwhile the quantity space of agricultural is relatively the same, and it’s tend to decreased overtime. This research using case study methods, with purposive sampling where the informant of this research selected by researcher by several considerations. And the subject in this research, the informant, have similarities in propertis and characteristic to each other. Based on the research and the discussion, that social capital small land’s peasant in the household’s fulfillment of living. That peasant with small land, utilized their social capital. With that social capital, small’s land peasant able to carried out the alternative income from source outside beside agricultural activities. Therefore they able to decrease the difficultiness of life in order to fulfill their household living. There’s several alternative source of income that been conducted by peasant in Komomayan Village in order to fulfill their household living by utilizing social capital that peasant’s have i.e livestock, having a debt and cooperation in managing agricultural land.<br /><strong>Keywords</strong>: Peasant, Social Capital, Household Living.</p><p> </p><p>Abstrak<br />Indonesia merupakan negara agraris, bahwa sektor pertanian memegang peranan penting dari keseluruhan perekonomian nasional. lahan pertanian memiliki peranan penting dalam produktifitas petani. Bahwa sektor pertanian mengalami kepadatan tenaga kerja, sementara luas lahan tetap, dan cenderung luas lahan semakin berkurang. Penelitian ini menggunakan metode studi kasus, dengan teknik purposive sampling yaitu informan yang dipilih atau ditentukan secara sengaja oleh peneliti dengan menggunakan pertimbangan tertentu. Serta Informan mimiliki kesamaan dengan sifat atau karakterisitik subjek penelitian ini. Berdasarkan penelitian dan pembahasan, bahwa modal sosial petani sawah berlahan sempit dalam pemenuhan nafkah rumah tangga. Petani sawah berlahan sempit memanfaatkan modal sosial yang dimilikinya. Dengan modal sosial tersebut, petani sawah berlahan sempit mampu menjalankan alternatif pendapatan lain diluar aktifitas bertani, dengan begitu mampu mengurangi kesukaran hidup dalam upaya pemenuhan nafkah rumah tangga. Berbagai alternatif pendapatan yang dilakukan petani sawah di Desa Kolomayan dalam upaya pemenuhan nafkah rumah tangga dengan memanfaatkan modal sosial yang dimilikinya seperti aktifitas beternak, berhutang, dan gotong royong pengerjaan lahan pertanian.<br /><strong>Kata Kunci</strong>: Petani, Modal Sosial, Nafkah Rumah Tangga.</p>

Strengthening of reinforced concrete elements can be carried out using a variety of materials and techniques. One of such materials is textile reinforced concrete (TRC). This material consists of a matrix, usually made of mortar, and textile as reinforcement. This study aims to produce mortar that meets the characteristic of a TRC matrix with respect to an adequate bond strength. The type of mortar developed in this study was fibre reinforced polyvinyl acetate (PVA) modified mortar. The bond strength of this material to the parent concrete was tested by the slant shear method. The results indicate that the amount of PVA content affects the magnitude of the bond strength. The higher the PVA content, the higher the bond strength. The results also confirm that the relationship between the bond strengths and their corresponding compressive strengths tends to be linear.
