Abstract

Environmental damage included the limestone mining process would remove the topsoil layer, reduce fertility, reduce microbial diversity and eliminate the vegetation that growth above it. Naturally, pioneer plants could grow to replace lost plants. Pioneer plants can be used as a reference for land recovery because these plants could grow on damaged land because they are associated with Plant Growth Promoting Rhizobacteria (PGPR). In addition, the presence of pioneer plants could inhibit soil erosion due to its root ability to hold the soil from scouring water. This study aimed to determine the characteristics of the initial natural succession process, namely the pioneer post-limestone mining community. This research was conducted by purposive random sampling method at three mining locations, namely Banjaragung Village, 5 years after mine, Maibit Village, 8 years after mine, and Rengel Village, 7 years after mine. Samples were taken for each of the 10 plots of 1x1 m size. The results of this study obtained 5 types of plants with the highest INP, namely: Lamium barbatum, Chromolena odoratum, Tridax procumbens, Waltheria indica, and Digitaria sanguinalis. While the highest diversity index is in the Village of Maibit, Rengel Sub-District, Tuban Regency after 8 years post-mining, which is 2.54.

Abstract

Cayenne pepper is a cultivated plant that is susceptible to flooding caused by poor drainage systems on agricultural land. Plants are more sensitive to flooding in the generative phase. The generative phase of the plant begins when it is approaching the flowering process until it bears fruit. The objectives of this study to examined the impact of cayenne pepper cultivar selection and repeated flooding on the average flowering time, fruiting time and the percentage of fruit loss. Three types of cayenne pepper cultivars were used, namely Mhanu XR, Sret and Cakra Hijau. Repeated flooding treatments were flooding 1 time, 2 times, 3 times and control without flooding. The data were analyzed using a two-way ANOVA statistical test. The results indicated that cultivar selection had a significant influence on the average flowering time, fruiting and fruit loss percentage. Meanwhile, repeated flooding and interaction between cultivars and repeated flooding had no significant effect on flowering time, fruiting and the percentage of fruit loss. The conclusion shows that the three cultivars of cayenne pepper have different responses to repeated flooding on the parameters of the time of flowering, fruiting and the percentage of fruit loss with the most adaptive cultivar, namely Cakra Hijau. The Cakra Hijau cultivar can be a good candidate in poor drainage than the Mhanu XR and Sret cultivars.

Abstract

Feed preparations are the most important thing in the field of animal husbandry. This activity is done every day and often takes a lot of time and effort, especially if done manually and to meet the needs of feed on livestock in large quantities. This obstacle is felt by breeders who are in the Kebonharjo Village Jatirogo district of the Tuban regency. To overcome this, it is necessary to conduct a Community Service program to hold feed kits for ruminant animals and provide knowledge in the efficiency of time and animal feeder personnel. Partners in this community service program are two farmers in Kebonharjo Village of Jatirogo District of Tuban Regency, with more than 15 cattle. In this program, the approach is to conduct direct observations and interviews to get data and problems faced by partners and to offer solutions that who will give to help partner problems. The solution provided by Tim community service is to hold an Electric and Portable Feed Countering tool (PPEP) so that the activities of providing animal feed by partners are more effective and efficient.

Abstract

The process of cayenne pepper seedling begins with soaking the seeds in liquid to break the dormancy of the seeds. The effect of soaking cayenne pepper seeds using PGPR solution obtained from the root system of cultivated plants, namely cayenne pepper (Capsicum frutescens L.), maize (Zea mays L.), peanuts (Arachys hypogaea L.), and rice (Oryza sativa L.) which had been harvested was the purpose of this study. Cayenne pepper seeds were soaked overnight using PGPR, then the seeds were sown in a planting medium mixed with soil, manure, compost and husk charcoal in a ratio of 2:1:1:1. Cayenne pepper seedling plantations were observed for 4 WAP. Using one-way ANOVA test for research data. Soaking cayenne pepper seeds using PGPR had a significant effect on seedling growth in terms of height, number of leaves, and stem diameter parameters with optimal treatment of 50% concentration. Meanwhile, PGPR immersion for seedling root length parameters did not have a significant effect.

Abstract

Penggunaan teknologi ramah lingkungan untuk budidaya pertanian sangat dianjurkan untuk mengurangi ketergantungan terhadap bahan-bahan kimia yang merusak lingkungan seperti pestisida. Salah satu teknologi ramah lingkungan yang banyak diadopsi petani adalah rekayasa habitat musuh alami hama menggunakan tumbuhan refugia. Tujuan penelitian ini adalah untuk menegtahui jumlah kunjungan dan keanekaragaman serta untuk mengetahui pola distribusi temporal arthropoda pada blok refugia pada lahan pertanian tanaman jagung (Zea mays) di Desa Cepokorejo Kecamatan Palang Kabupaten Tuban. Data berupa kunjungan arthropoda pada blok refugia (Amaranthus spinosus, Cyperus byllinga, Eclipta prostrata, Portulaca oleracea, Phyllanthus niruri L.) diperoleh dengan pengamatan secara langsung sementara keanekaragaman didapatkan dengan cara menghitung dengan rumus indeks diversitas dan pola distribusi temporal dihitung dengan menggunakan Indeks Morisita.

Abstract

Observation of leaves, especially the epidermis, is often the focus of research because this part is directly exposed to the environment, so changes that occur in this part can indicate changes in the plant's metabolism. Observation of leaf skin requires preparation in advance, especially in observing wet preparations. There are various methods of leaf skin sample preparation including the printing method and leaf paradermal slices. The purpose of this study was to compare leaf preparations with preparations using the printing method and paradermal slices carried out by students of the Biology at PGRI Ronggolawe University in the Plant Anatomy Practicum course. Data in the form of preparations of leaves Morinda citrifolia and Solanum melongen were observed using an electric microscope with a magnification of 400 times, while Ixora sp. leaves were observed using a light microscope with a magnification of 400 times. The results of the study can be concluded that the printing and paradermal incision methods are optimal for the purpose of observing different leaf characters. The optimal printing method is used on leaves that have little or no trichomes and is very good for observing stomatal openings. While the paradermal slice method is good for use on leaves that have trichomes or not, the use of this method requires good practical skills, besides this method cannot represent leaf stomatal openings at the time of observation because the stomata tend to close.
