SUMMARYTen Armillaria isolates, collected from various host plants and widespread geographical origins in tropical Africa, were cultivated on orange fragments in the presence of water and two different culture media in order to optimize enzyme and mycelial cord production. Seven enzymes involved in the primary metabolism of nitrogen and carbon (glutamate dehydrogenases, aspartate aminotransferase, malate dehydrogenase, glucose 6-phosphate dehydrogenase, 6-phospbogluconatt dehydrogenase and isocitrate dehydrogenase) were extracted from the mycelial cords and analyzed by polyacrylamide gel electrophoresis. Cluster analy.sis based on calculated similarity i-alues derived from isozyme banding patterns separated the isolates into fi\'e groups. Two isolates considered as belonging to A. metlea ssp. africana (an African species closely related to European A. metlea) were present in a clearly separated cluster when compared to the other isolate groups. Two Kenyan isolates, belonging to an as yet unnamed biological species, which w ere characterized by the production of few slow growing mycelial cords, were also found in a separate cluster with slightly greater similarit\' coefficients to the other isolates. The six other isolates, referred to as isolates of A. heimii (a highly variable species with different sexual systems) fell into three sub^clusters of variable homology. The two bomothallic heimii isolates from Tanzania and Malawi, which were \ery closely related, displaying 100 "" isozyme similarity, exhibited a higher degree of similarit>' with the two other homothalhc heimii isolates from Zimbabwe and Congo, than with the two heterothailic unifactorial heimti isolates from Cameroon and Gabon. The value of isozymes in the classification of African Armtllaria spp. is discussed.

<p>Rice for the Poor (Rastra) and Non-Cash Food Assistance (BPNT) Programs are among the policy instruments for poverty alleviation. Rastra, formerly a subsidy policy, was partly transformed into assistance design through BPNT Program since 2017. This study aims to assess effectiveness of Rastra and BPNT in terms of 6R aspects, i.e. Right Target, Right Amount, Right Price, Right Time, Right Quality, and Right Administration. Primary data were collected from sample cities implementing these programs. This study used both quantitative and qualitative approaches. It is necessary to improve target beneficiaries, assistance receiving time, rice quality, and e-warong readiness. As instruments of poverty alleviation, Rastra and BPNT were implemented in an integrated manner based on the surplus and deficit areas. Subsidy design (Rastra) transformation into non-cash food assistance (BPNT) should be implemented gradually. Bulog needs to improve farmers’ rice purchase and to increase government’s rice reserve.</p><p> </p><p>Abstrak</p><p>Program Beras Sejahtera (Rastra) dan Bantuan Pangan Non-Tunai (BPNT) merupakan salah satu instrumen kebijakan penting dalam penanggulangan kemiskinan bagi masyarakat miskin berpenghasilan rendah. Sesuai arahan Presiden RI tentang bantuan sosial dan keuangan inklusif, maka sejak tahun 2017 Rastra yang merupakan kebijakan subsidi sebagian ditransformasi menjadi pola bantuan melalui Program BPNT. Penelitian ini bertujuan untuk mengkaji efektivitas pelaksanaan Rastra dan BPNT (aspek 6T: Tepat Sasaran, Tepat Jumlah, Tepat Harga, Tepat Waktu, Tepat Kualitas, dan Tepat Administrasi) dan merumuskan saran kebijakan perbaikan pelaksanaan Rastra dan BPNT. Cakupan kajian dan data yang digunakan adalah pada tingkat nasional dengan keterwakilan dari masing-masing kota pelaksana program. Metode kajian menggunakan analisis kuantitatif dan kualitatif. Pelaksanaan Rastra dan BPNT dipandang perlu dilakukan perbaikan dari sisi sasaran penerima, waktu penerimaan bantuan, kualitas beras, dan kesiapan e-warong di semua wilayah. Sebagai instrumen penanggulangan kemiskinan, Rastra dan BPNT dilaksanakan secara terpadu dengan mempertimbangkan wilayah surplus dan deficit. Proses transformasi pola subsidi (Rastra) menjadi pola bantuan pangan (BPNT) juga harus dilakukan secara bertahap sesuai kesiapan infrastrukturnya.  Selain itu mengingat kebijakan Rastra dan BPNT sangat terkait dengan peran dan kapasitas Bulog dalam melakukan serapan gabah-beras dari petani dan menjaga stabilisasi harga beras, maka pemerintah perlu meningkatkan Cadangan Beras Pemerintah.</p>

Corn is the second carbohydrate source after rice that has a role in achieving food security, supplying sufficient animal feed, and even lately is used as feedstock for alternative energy (biofuel). The importance of corn in a national food system can be seen from a current government policy that has set a target to achieve corn selfsufficiency within three years or in 2017. To formulate accurate operational policies for achieving corn selfsufficiency, various information are needed, among others are corn farming performance and competitiveness. This study aims to analyze corn farming profitability, competitiveness, and strategy for improving its competitiveness using a Policy Analysis Matrix (PAM) approach. Main data used were cost structure of corn farming in planting season of 2011/2012 from Statistics Indonesia. The results showed that corn farming in Indonesia was profitable, with the financial benefits was around Rp 6.7 million/ha with R/C ratio 1.73, and economic profit reached Rp 8.7 million/ha with R/C ratio 1.90. National corn farming also had a strong competitive ability, as indicated by DRCR and PCR values 0.48 and 0.54, respectively. Therefore, corn farming in Indonesia was efficient economically and financially or had comparative and competitive advantages. This information can be used as a guidance in formulation of operational policies to increase corn production in order to fulfill domestic needs or even for export. To boost corn production, besides policies related to increasing efficiency and productivity in production subsystem, the policies should also be directed to improve efficiency and performance in other agribusiness subsystems.

<p>Fertilizer is one of important production factors in food farming to gain high productivity. Efforts to manage procurement, distribution, and proper fertilizer application have been regulated, implemented, and controlled by the government. However, complaints related to fertilizer distribution problems still exist. This study aims to analyze national fertilizer performance, especially fertilizer policy for food sector, fertilizer industry, and farmer dynamics in formulating fertilizer needs and its application; and to formulate fertilizer policy alternatives that can increase fertilizer distribution efficiency and use of budget subsidy. Coverage and data of this study were at national level. Analytical methods of this study were both quantitative and qualitative descriptive approaches. The main finding of this study was a formulation of four policy alternatives pertaining distribution mean of direct fertilizer subsidy delivered to farmers. Implementation of these policy alternatives requires availability of accurate data on rice farmers, agricultural land ownership and use, and food farming system profile nationwide. In the short run, in order to increase distribution efficiency of subsidized fertilizer to farmers, it is recommended that some adjustments to the current fertilizer policy must be done on price of natural gas as raw material for Urea, level of subsidized price of fertilizers paid by farmers, document of definitive plan of fertilizer needs of farmer groups (RDKK), and function of fertilizer supervision commission at regional levels. </p><p> </p><p align="left">Abstrak</p><p>Pupuk merupakan salah satu faktor produksi penting dalam usaha tani pangan untuk memperoleh produktivitas tinggi. Upaya mengelola pengadaan, penyaluran, dan penggunaan pupuk telah diatur, dilaksanakan, dan diawasi pemerintah, namun keluhan terkait dengan permasalahan penyaluran pupuk bersubsidi masih saja terjadi. Pengkajian ini bertujuan untuk menganalis keragaan perpupukan nasional, terutama kebijakan penyaluran pupuk bersubsidi untuk subsektor pangan, industri pupuk nasional, dan dinamika petani dalam penyusunan kebutuhan serta pemanfaatan pupuk; dan merumuskan alternatif kebijakan perpupukan yang dapat meningkatkan efisiensi dalam penyaluran dan anggaran subsidi pupuk. Cakupan kajian dan data yang digunakan adalah pada tingkat nasional. Metode kajian menggunakan analisis kuantitatif dan deskriptif kualitatif. Hasil  utama kajian ini berupa formulasi empat alternatif kebijakan cara penyaluran anggaran subsidi pupuk langsung diberikan kepada petani. Implementasi alernatif kebijakan tersebut mempersyaratkan tersedianya data yang akurat tentang petani padi, penguasaan dan pengusahaan lahan pertanian, dan profil usaha tani pangan secara nasional. Dalam jangka pendek, untuk meningkatkan efisiensi penyaluran pupuk bersubsidi ke petani disarankan dilakukan beberapa penyesuaian atas kebijakan perpupukan saat ini, yaitu harga gas bumi sebagai bahan baku Urea, harga eceran tertinggi pupuk bersubsidi, dokumen rencana definitif kebutuhan kelompok (RDKK), dan fungsi komisi pengawasan pupuk di daerah.</p>

This study aimed to examine the effect of turmeric and garlic inclusion to fermented Sauropus androgynus-bay leaves (FSBL) containing diet on fat deposition, and chemical composition of broiler meats. Two hundred 15-day-old female broilers were distributed into 5 treatment groups with 4 replications as follows. Control feeds with commercial feed additive (T0); Feeds with 1.25% FSBL (T1); Feed with FSBL plus 1 g turmeric (T2); Feed with FSBL plus 2 g garlic (T3); Feed with FSBL plus 1 g of turmeric and 2 g garlic (T4). It was shown that the fat deposition in the abdomen was significantly affected (P<0.01). Furthermore, the inclusion of turmeric and garlic to FSBL containing diet did not affect fat, protein, moisture and ash contents, but increased arginine, methionine and histidine (P<0.01). The addition of turmeric and/or garlic to the FSBL containing diet significantly influenced lauric acid, myristic acid, linolenic acid, cis-11-eicosenoic acid, cis-4,7,10,13,16,19-docosahexaenoic acid (P<0.05), n-3 fatty acid and n-6/n-3 fatty acid ratio (P<0.01). In conclusion, turmeric plus garlic supplementation improved amino acid profiles and changed fatty acid profiles. The possible interaction should be considered when we formulated feed additive from medicinal plant mixtures
