Abstract

Penelitian ini dilakukan dengan fokus melakukan restorasi ekosistem wilayah pesisir dengan pendekatan keterpaduan di Kabupaten Gesik dengan mengambil contoh di dua kecamatan yaitu Kecamatan Ujung pangkah dan Kecamatan Bungah. Restorasi merupakan upaya untuk memperbaiki kembali kondisi wilayah pesisir yang sudah rusak lingkungannya akibat dari kegiatan manusia yang makin tidak rasional dan karena proses alam yang perubahannya sangat dtrastis akibat pengaruh global warming. Restorasi berupaya untuk melakukan perbaikan untuk mengembalikannya ke kondisi semula, walaupun untuk mencapai pemulihan kepada kondisi semula masih memerlukan penelitian lebih lanjut. Hal ini mengingat kondisi yang mendukung seperti kondisi hidrologi sudah mengalami perubahan.Metode yang digunakan untuk mencapai tujuan penelitian ini digunakan pendekatan kombinasi yaitu penelitian diskriptif, penelitian partisipatif dan penelitian eksploratif. Penelitian diskriptif terkait dengan observasi dilapang untuk menilai kondisi kedua kabupaten baik secara biogeofisik, sosial ekonomi dan sosial budaya. Untuk penelitian partisipatif berkaitan dengan menjaring aspirasi dan harapan masyarakat melalui wawancara. Sedangkan penelitian eksploratif digunakan model Partial Least Square (PLS) dan Analitycal Hierarchy Process (AHP). Disamping itu untuk merumuskan model restorasi ekosistem terkait pengelolaan digunakan model co-management.Hasil penelitian menunjukkan bahwa hubungan antara masyarakat dengan upaya restorasi ekosistem ternyata sangat kuat berperan, termasuk upaya restorasi perlu dilakukan secara terpadu. Hal ini ditunjukkan oleh hasil PLS. Sedangkan ekosistem pesisir mana yang harus didahulukan untuk ditangani AHP menyatakan bahwa prioritas utama adalah mangrove, kemudian terumbu karang, diikuti dengan kawasan estuari dan terakhir padang lamun. Berdasarkan itu maka model co-management mensyaratkan perlu adanya kolaborasi diantara masyarakat, pemerintah dan swasta. Kolaborasi tersebut dipayungi oleh kerangka strategi yang memuat visi, misi, tujuan dan prioritas strategi.

Abstract

Waktu panen diduga berpengaruh terhadap kandungan glukomannan pada umbi porang. Penelitian ini bertujuan untuk mengetahui pengaruh waktu panen terhadap dinamika kandungan glukomannan pada umbi porang. Glukomannan diekstraksi dari umbi porang yang diperoleh pada saat dua minggu sebelum tanaman rebah, pada saat tanaman rebah dan dua minggu setelah tanaman rebah. Glukomannan diperoleh dengan menggunakan metode ekstraksi yang telah dimodifikasi. Parameter yang diamati meliputi kandungan glukomannan dan berat kering umbi. Data kandungan glukomannan pada umbi dianalisis dengan One way ANOVA dan dilanjutkan dengan Tukey α 0,05. Sedangkan hubungan antara kandungan glukomannan terhadap berat umbi dianalisis dengan menggunakan Uji Korelasi Bivariate. Dari hasil analisis, Kadar glukomannan cenderung lebih tinggi pada umbi porang yang dipanen saat tanaman rebah dibandingkan dengan glukomannan pada umbi yang diperoleh ketika sebelum dan setelah tanaman rebah yaitu sebesar 29,10 ± 4,57 g/100 g. Peningkatan kandungan glukomannan dapat meningkatkan berat umbi porang.

Abstract

Fall seedling diseases (damping-off) caused by Sclerotium rolfsii is one factor in low productivity of soybean in Indonesia, which may cause loss results achieved 30-75% depending on the level of attacks. Given the character of soil borne diseases (soil borne), then all control efforts through many obstacles, either because the pathogen can survive for decades in the form resistant propagules (Sclerotium) although there is no host for the development.This study aimed to find ways to control the disease by utilizing the potential of natural biological materials and find ways to get control for effective results. For this purpose the various steps of research has been conducted both in laboratory and greenhouse using experimental research design (completely randomized design) and F test to see the difference. The results show that in the first year of research proven to provide results tuba root extract is effective in controlling pathogens. Streptomyces isolates proved to be antagonistic to Sclerotium rolfsii, and when combined with mycorrhizae (AM) will be able to increase its effectiveness. Introduction of inoculum will likely increase their effectiveness when mixed directly into cropping land that can be done as a biological fertilizer just before planting. There is a tendency that the combination treatment between biopesticide will help the effectiveness of its control, though not necessarily affect the production, so the increase in soybean production is due to the protection of soybean from the dead early in the seedling that can suppress up to 50 percent compared with the control.

Abstract

Porang is higher plant which has unique morphology. Tuber, petiole and lamina are the main part of its body. Even Porang doesn’t have true stem, only petiole, its lamina not simple leaves but compound leaves with special pattern. Branching patterns of petiolule are not same in different age. Therefore the aim of research was to observe branching pattern of petiolule from Porang age 1-4 that lived in their native habitat i.e. forest. The research was conducted in secondary forest in Sumberbendo village, Madiun.  Determination porang age was helped by expert farmer that worked with porang for long time. The result showed that Porang age 1 had petiolule with braching type 1-0. Porang age 2 was 1-3, Porang age 3 was 1-3-2, and Porang age 4 was 1-3-2-2. The petiolule which acted as a base of new branch had one or few single simple leaf. The leave could be both sinus and un-sinus leaves located in between two initial or base branching. The position of the leaves were opposite or alternate along with petiolule. If location single leaf just in point branching, the new petiolule morphology was not be considered as petiolule but midrib.

Abstract

Inhibition of intestinal α-amylase and α-glucosidase is an important strategy to control post-prandial hyperglycemia associated with diabetes mellitus. In vitro inhibitory effects of crude extracts of seaweed against α-amylase and α-glucosidase were studied. Crude ethyl acetate extracts of Sargassum aquifolium were the stronger inhibitor to α-amylase and α-glucosidase than others. Furthermore, Sargassum aquifolium ethyl acetate extract significantly suppressed the rise in postprandial glucose level after oral administration of glucose in normal rats. The results of this study suggest that the crude Sargassum aquifolium extract may suppress the rise in postprandial hyperglycemia in vivo in part, through inhibition of alpha amylase and glucosidase.

Abstract

This research was conducted to know the effect of noni leaves extract (Morinda citrifolia L.) supplementation in feed on physical quality of broiler breast meat such as pH, Water Holding Capacity (WHC), Cooking Loss (CL), and tenderness. Ninety six 8-days old broiler chickens strain Lohmann and of undifferentiated sex (unsexed) were used in this research. The broiler chickens will be reared until 35-days old. The research method was experimental using Completely Randomized Design (CRD) with six treatments and four replications, each replication consisted of four broiler chickens. The treatments consisted of P0 (Basal Feed), P1 (Basal Feed + tetracycline 0.05%), P2 (Basal Feed + noni leaves extract 0.05%), P3 (Basal feed + noni leaves extract 0.1%), P4 (Basal feed + noni leaves extract 0.15%), P5 (Basal feed + noni leaves extract 0.2%). The data were analyzed by ANOVA and continued by Least Significant Difference (LSD) test if there was significantly different result. The results showed that noni leaves extract did not give significant effect (P>0.05) on meat pH, water holding capacity (WHC), cooking loss (CL), and tenderness. However, these results were still acceptable normally such as pH between 5.38-5.57, water holding capacity 34.13-45.64%, cooking loss 33.05-36.97%, but tenderness 16.22-20.57N were less acceptable. The research concluded that supplementation of noni leaves extract (Morinda citrifolia L.) in feed did not increase physical quality of broiler breast meat on pH, Water Holding Capacity (WHC), Cooking Loss (CL), and tenderness.
