Abstract

Vinase merupakan hasil samping akhir dari proses pengolahan bioetanol yang berbentuk cair. Di Indonesia, produksi bioetanol masih mengandalkan molases tebu (Saccharum officinarum L.) sebagai bahan baku. Vinase berpotensi mencemari lingkungan, namun di sisi lain juga mengandung bahan organik, potasium, nitrogen, fosfor, dan berbagai unsur hara lainnya yang bermanfaat untuk pertumbuhan tanaman. Studi ini bertujuan untuk mengulas potensi pemanfaatan vinase sebagai produk samping produksi bioetanol berbasis tebu untuk pemupukan sekaligus irigasi (fertigasi) di perkebunan tebu di Indonesia. Metode yang digunakan adalah kajian literatur. Fertigasi dengan menggunakan vinase di lahan tebu dapat memberikan dampak positif terhadap sifat fisika, kimia, dan biologi tanah serta pertumbuhan tebu. Vinase bahkan berpotensi menjadi bahan substitusi pupuk potasium anorganik.

Abstract

Malnutrition is one of the serious problems encountered by Indonesia. This research aimed to identify local knowledge and practice on entomophagy in Datengan Village, Kediri, East Java, Indonesia. The entomophagy data were collected by the qualitative approach. The edible insects in this study were honey bee (i.e., Apis mellifera, A. cerana, and A. dorsata) and flying termites (i.e., Macrotermes gilvus and Odontotermes javanicus). All aspects of the local and scientific name, halal status, harvest period, local value, and how to collect, prepare, cook and serve have been described in this article. According to the Indonesian Council of Religious Scholars, termites are halal or allowed to be consumed (it could otherwise be haram, if people feel disgusted). On the other hand, consuming bees (A. mellifera, A. cerana, and A. dorsata) is haram to eat adult bees. Meanwhile, consuming bees that are still in the form of larvae is halal, but it is to be haram if they are eaten separately with honey or hive. There were five challenges in entomophagy such as disgust, allergy, inferior, halal status, and complicated processing methods.

Abstract

The eruption in 2010 of Merapi Mount changed the diversity of plant species. The objective of this research was to investigate the diversity of plant species on Mount Merapi National Park (MMNP). The sampling area was divided into three different levels of damage (heavy, medium, and mirror). The research was conducted by using line-transect and quadrat method.  We were conducted using line-transect and quadrat method. The research showed that Acacia decurrens has the highest Important Value Index (IVI) at the heavy damage area of Cangkringan Resort (CR) and Kemalang Resort (KR) as well as in mirror damage area of Selo Resort (SR). The most important species at medium damage area of Dukun Resort (DR) were Albizia lopantha and Pinus merkusii. The pioneer species at Non-Cover Area (NCA) among others were Trema cannabina, Pityrogramma calomelanos, Imperata cylindrical, Buddleja asiatica, Anaphalis javanica. Eupatorium riparium were the most important species of herb in all four locations based on SIMPER, but it was not dominant in NCA. The homogeneity of plant in Cangkringan Resort and Selo Resort (C D E) were normally distributed, whereas NCA, DR, and KR (E ≥ D) were homogeneous. Analysis of non-metric multidimensional scaling and value of ANOSIM (RANOSIM =0.69; p = 0.0001) demonstrated that all site locations have significance differences. This research was not only focusing on survey of vegetation diversity, but also frequency class distribution. Through this study of frequency of species provides a database for conservation biodiversity and restoration program.
