Abstract

Water hyacinth is a wild aquatic plant that grows quickly. The growth of water hyacinth need to be controled to prevent the flood and not to disturb paddy irrigation channels. Grass carp as herbivorous fish is used as natural predator to reduce the population of water hyacinth. The interaction between water hyacinth and grass carp is modeled using the prey-predator system. In this model there are harvest factors and predation factors using Holling type III. The optimal control problem is applied to minimize the mass of water hyacinth and harvest efforts of water hyacinth and maximize the mass of grass carp. The solution uses the Pontryagin Principle. The result is that the harvesting of water hyacinth and the grass carp can minimize the water hyacinth biomass at the end of time. Eceng gondok merupakan tanaman liar di perairan yang tumbuh dengan cepat. Pertumbuhannya perlu dikendalikan agar tidak menyebabkan banjir dan tidak mengganggu saluran irigasi persawahan. Ikan grass carp sebagai ikan herbivora digunakan sebagai predator alami untuk mengurangi populasi eceng gondok. Hubungan antara eceng gondok dan ikan grass carp dimodelkan dengan menggunakan sistem prey-predator. Pada model ini terdapat faktor pemanenan dan faktor predasi menggunakan Holling tipe III. Masalah kendali optimal diterapkan dengan tujuan untuk meminimumkan massa eceng gondok dan usaha pemanenan eceng gondok serta memaksimumkan massa ikan grass carp. Penyelesaiannya menggunakan Prinsip Pontryagin. Hasilnya dengan adanya usaha pemanenan eceng gondok dan pengadaan ikan grass carp dapat meminimumkan biomassa eceng gondok di waktu akhir.

Abstract

This study aims to examine the knowledge of the community in Tiremenggal Village in utilizing food plants for immunonutrients. The research method used consists of two stages: the first stage of inventorying the level of community knowledge with exploratory survey methods and participatory ethnobotanical assessment through in-depth interviews (deep interviews) and structured (open-ended). The second stage is collecting data on the use of food plants using semi-structured interviews. The results showed that people's knowledge about food plants was obtained from asking other people (26%). The types of food plants identified were as many as 30 species covering staple food and additional food categories. In conclusion, the community's knowledge and ability in Tiremenggal village to utilize, compose and process traditional food plants as a source of immunonutrientts can be seen from the description of the aspects of their activities and activities.

Abstract

Kepuh is a species of plant from the Malvaceae family that has a large body. The distribution of Kepuh is found in Southeast Asia, especially in the tropics and subtropics. Kepuh is one of the endangered species, because it is rarely found in primary and secondary forests. In terms of utilization, it is still very limited, only planted as yard plant and garden fences. This study aims to determine the diversity of Kepuh in Lamongan district. This type of research is descriptive analytic with a quantitative approach. Data collection techniques used are survey and observation. The results of this study are the diversity of Kepuh includes (1) the diversity of families that dominates the Fabaceae family, (2) the diversity of habitus of Kepuh that dominates is seedlings, (3) the diversity of habitats that dominates is plantations land, (4) the highest INP value of Kepuh is 28,29% in the medium category.

Abstract

Bacillus sp. are gram positive bacteria. Thesa bacteria are able to decompose complax compounds into simpler compounds, to reduce thze negative effects of chemical pesticides, it is necessary to develop alternative methods that are safer and environmentally friendly to control plant diseases. This macroscopic observation only looks at the colony and cannot tell whether these bacteria have an effect on plants. Bacillus sp. it includes a distinct physiological group of on-pathogenic bacteria, which are realitively easy to manipulate genetically and simple to cultuure, which strengthens their suitability for industrial purposes. Macroscopic observation of Bacillus sp. this gets the number of colonies ±20. Further observation are needed to find aot whether it is good for use for the community.

Abstract

The Zingiberaceae tribe is a plant that has the potential as a traditional medicine that is widely used by the community in curing various diseases. This study aims to determine the diversity and utilization of Zingiberaceae tribal plants as traditional medicine in Tiremenggal village. The method used in this study is a descriptive method with qualitative and quantitative approaches, to determine the analysis of the value of community use of medicinal plants analyzed by the ICS (Indexs of Cultural Significance) method. There are 5 families of Zingiberaceae which are used by the people of Tiremenggal village, namely ginger, turmeric, galangal, kencur and temulawak. The plant that is often used by the community as a treatment is ginger. The part that is used as medicine is the rhizome, which is mostly used to treat stomach pain, taken by mouth. Medicinal plants that are used by the community traditionally are still used today even though the preparation is done simply.

Abstract

The problem faced by farmers in Bulumargi village, Babat district, Lamongan Regency is pest attack. Pest attack control carried out by farmers using synthetic pesticides. The use synthetic pesticides if carried out continuously gives impacts such as pest resistance, pest resurgence, death of onotarger animalincluding natural enemies, emergence of secondary pest explosions, pesticide residues in plant and environment. Synthetic pesticide residues found in agricultural products very dangerous if consumed for a long period of time, so a solution is needed that can reduce farmers' losses due to pests on crops. The purpose of this research is to eradicate pests using refugia plants. The research method used was socialization with several stages, counseling, discussions and aplications in rice fields. The result of this research is that the community has increased their knowledge and skills in the use of refugia plants. The conclusion of this research is the increasing public knowledge in utilizing refugia plants to reduce the use of synthetic pesticides and increase rice production in the long term.
