Sistem Resi Gudang Dalam Perspektif Kelembagaan Pengelola Dan Pengguna Di Kabupaten Subang: Studi Kasus KSU Annisa
EnglishA drop in agricultural commodity prices at harvest season and difficulty of obtaining farm financing are problems often faced by farmers . Warehouse Receipt System (WRS) is expected to be one among other government efforts to facilitate farmers to cope with these problems. WRS is a delay selling strategy by farmers in a way to temporarily storage their products in the warehouse and sell them at the right time to get the possi ble highest price . Warehouse Receipt ( WR) may be used by farmers as collateral to get loan from designated b ank and other financial institution. In general, the implementation of the WRS has been slow and has not been widely used by farmers and other WRS target participants. This paper aims to analyze policy in the implementation of WRS with regard to institutional perspectives of service supplier and users in Subang Regency and to formulate policy options for future performance improvement. Some findings indicate that small land size, the immediate need of cash during harvest season and famers' limited ability to meet quality standards are regarded as constraining factors for farmers to utilize WRS. Lacks of understanding of the concept , benefits, and impl ementation procedures of WRS remain fundamental problems. These occur at the farm level and in related agencies including local government officials. Dissemination and advocacy of WRS to farmers, farmer groups and all stakeholders need to be undertaken in a wider scale . An active role of local government is urgently needed to accelerate the dissemination of SRG. IndonesiaMerosotnya harga komoditas pertanian saat musim panen dan kesulitan memperoleh pembiayaan USAha tani merupakan fenomena yang seringkali dihadapi oleh para petani. Sistem Resi Gudang (SRG) diharapkan menjadi salah satu upaya pemerintah untuk memfasilitasi petani dan peserta skim SRG lainnya dalam menghadapi permasalahan tersebut. SRG merupakan strategi tunda jual yang dilakukan petani dengan cara menyimpan hasil panennya di gudang pengelola SRG dan menjualnya pada saat yang tepat untuk memperoleh harga yang tertinggi. Resi Gudang (RG) dapat dipergunakan oleh para petani sebagai jaminan untuk memperoleh kredit perbankan atau lembaga keuangan lain yang ditunjuk. Secara umum pelaksanaan SRG masih berjalan lambat dan belum banyak dimanfaatkan oleh para petani dan sasaran peserta skim SRG lainnya. Penulisan makalah ini bertujuan untuk menganalisis kebijakan penyelenggaraan SRG dalam perspektif kelembagaan pengelola dan pengguna di Kabupaten Subang dan merumuskan alternatif kebijakan untuk meningkatkan kinerja SRG. Terbatasnya luas lahan garapan, kebutuhan untuk memperoleh uang tunai serta persyaratan kualitas dan volume minimal produk yang ditetapkan pengelola SRG, merupakan pembatas tingkat partisipasi petani dalam memanfaatkan SRG. Keterbatasan pemahaman tentang konsep dan manfaat SRG maupun tata cara pelaksanaannya menjadi permasalahan mendasar, tidak hanya di tingkat petani sebagai sasaran, tetapi juga terjadi pada para petugas pelaksana instansi terkait, termasuk aparat Pemda setempat. Oleh karenanya, sosialisasi dan advokasi tentang SRG kepada petani, kelompok tani, dan semua pemangku kepentingan perlu ditingkatkan dan diperluas. Peran aktif Pemda setempat sangat dibutuhkan untuk mempercepat penyebarluasan SRG

Pengaruh Variasi Agregat Terhadap Kekuatan Dan Berat Kuda-kuda Beton Komposit Tulangan Bambu Dengan Serat Bambu
Yang sering digunakan pada konstruksi rumah adalah kuda-kuda beton bertulang. Alasan menggunakan kuda-kuda beton bertulang karena mudah diaplikasikan di dalam konstruksi. Oleh karena itu perlu adanya alternatif agar kuda – kuda beton menjadi konstruksi yang ringan dengan mengunakan tulangan bambu. Penggunaan tulangan bambu adalah suatu opsi yang baik karena memiliki kekuatan yang cukup tinggi dan memiliki berat sendiri yang lebih ringan daripada tulangan baja. Untuk lebih menerapkan konsep ringan pada kuda – kuda, maka dalam penelitian ini menggunakan variasi agregat kasar yang lebih ringan daripada agregat kasar konvensional (batu kerikil), serta serat bambu dapat mengatasi kelemahan beton terhadap kekuatan tarik. Penelitian ini membahas tentang pengaruh agregat kasar terhadap kekuatan dan berat kuda-kuda beton komposit tulangan bambu dengan serat bambu. Variasi agregat kasar yang digunakan adalah batu pumice dan limbah batu bata. Kuda-kuda yang memiliki sudut sebesar 35° dibuat sebanyak 3 buah untuk setiap variasinya. Hasil penelitian menunjukkan bahwa kuda-kuda beragregat kasar limbah batu bata dengan serat bambu memiliki berat sendiri rata-rata yang lebih ringan sebesar 84,15 kg dan mampu menahan beban lebih baik sebesar 3766,67 kg daripada yang beragregat kasar batu kerikil. Namun kuda – kuda agregat batu kerikil memiliki kekakuan yang lebih besar dibandingkan dengan kuda-kuda beragregat kasar batu pumice dan limbah batu bata
