Abstract

ABSTRAKPenelitian ini bertujuan untuk menganalisis struktur food web dalam pola interaksi serangga-gulma pada ekosistem sawah surjan dan lembaran yang dikelola secara organik dan konvensional.        Penelitian dilakukan pada enam petak sawah surjan dan enam petak sawah lembaran di daerah Kulon Progo dalam dua musim tanam pada bulan Desember 2009 sampai Juli 2010.  Baik sawah surjan maupun sawah lembaran, masing-masing dibedakan dalam dua pengelolaan, yaitu pengelolaan organik dan konvensional, dengan ulangan masing-masing tiga petak.  Lima plot ukuran 1x1 m ditempatkan pada masing-masing petak yang tidak diubah posisinya sampai berakhir satu musim tanam. Inti dari penelitian lapangan ini adalah menghitung jenis dan kelimpahan gulma setiap tiga minggu sekali untuk setiap petak, demikian juga untuk jenis dan kelimpahan dari serangga herbivora untuk setiap jenis tanaman/gulma pada setiap plot. Analisis data dilakukan dengan program Bipartite in R statistics 2.12.0, dan dilakukan uji pengaruh tipe sawah dan cara pengelolaan lahan terhadap struktur dan network level (jumlah jenis trofik atas, jumlah jenis trofik bawah, keterhubungan, diversitas Shannon, dan kemerataan interaksi) dengan menggunakan General Linear Model (GLM) dalam program SPSS 17.0. Hasil penelitian sawah surjan yang dikelola secara organik mempunyai pola interaksi serangga-gulma yang lebih kompleks dengan lebih banyak link interaksi, jumlah jenis trofik atas dan bawah, indeks diversitas Shannon, dan kemerataan interaksi yang lebih tinggi, serta keterhubungan (connectance) yang lebih rendah. ABSRACTThe aims of this research was to analyse food web structure of insect-weed interaction in surjan and lembaran rice field ecosystems under organic and conventional managements. We observed six rice fields of local farms called “surjan” rice fields, and six rice fields of “lembaran” farms in Kulon Progo District, central Java, in two planting seasons in December 2009 until July 2010.  They were divided into two types of managements, i.e. organic and conventional farming.  Five 1x1 m plots per field were taken as sampling units and were not changed until the end of the planting season.  The type and abundance of each type of weeds were recorded every three weeks, and counted for accordingly.  In the similar way, type and abundance of herbivore insects were observed for each weed in each plot.  Data analyses were conducted in Bipartite program of R Statistics 2.12.0, and the effect of farm type and management on network level of food web structure (number of higher trophic species, number of lower trophic species, connectane, Shannon diversity index and interaction evenness) was tested per field using General Linear Model (GLM) with SPSS Statistics 17.0. The result of this research is that organic surjan rice farm had more much links in food web structure, more number of higher and lower trophic species, Shannon diversity and interaction evenness, and less connectance.

Abstract

To solve problems accurately and focused, students must have problem solving skills. The purpose of this study was to evaluate class X students of SMA N 4 Yogyakarta in the even semester of the academic year. This study uses a descriptive quantitative research method. As a sample used simple random sampling. According to Polya, there are four indicators of problem-solving ability: Understanding the problem, preparing, implementing plans, and re-checking are steps that must be taken. On the topic of environmental change, the test instrument revealed that students' problem-solving abilities were in the high range. But if we look at each indicator separately, we can see that all four of them belong to a group. This is because students do not double-check their written answers and continue to doubt these answers. The non-test instrument study, on the other hand, the non-test instrument study found that students' problem solving abilities were very good. Based on these findings, it can be concluded that the students' overall problem solving abilities are of a high standard. Because research findings cannot be used with all materials, problem solving skills must be tested with different materials.

Abstract

Bugel is one of districts in Kulon Progo Regency that uses Surjan Method in planting rice  as their local agricultural system. One of major problems faced by the farmer during harvest season is the drop of the yields’price which then lead to the financial loss for the farmers. In order to anticipate the same issue happens in the next harvest season, farmers in subdistrict Bugel, District of Panjaten, Kulon progo Regency want to have a training in regard to process the food such as Red Chilli and Shallot,   therefore rotten and damaged yields due to the longer time of storage can be reduced or even avoided. After being processed through the postharvest techniques, those yields are expected to increase in prices thus they will bring profit and more income for the citizens. This training aims to introduce postharvest techniques that can be used to store the yields longer and also to train citizens on food processing  which resulted in finer product and  ultimately can be sold in  higher price. Red Chilli and Shallots are the main yields harvested during the harvest season outside Rice. Two types of Sambal made from red Chilli and processed food of Shallots (Fried Shallot) are made during the practice. These products hopefully will last longer in storage and also can be sold in higher price compared to the fresh ones.Customer satisfactory surveys results showed that attendance were responded positively towards the training. Based on the evaluation, citizens wish for  similar training in the future with topic regarding the health and safety of the products as well as the marketing aspect of them.

Abstract

Soil contamination by pesticides is one of the world’s most pressing environmental issues. The widespread use of Organophosphate pesticides (OPPs) in agriculture has led to biological diversity changes. The indigenous bacterial community played significant roles in the remediation of soil contaminated with OPPs. This study examines the overall bacterial community composition of three agricultural fields in Yogyakarta, Java, Indonesia, that were exposed to OPPs. The agricultural field was divided into zones near the beach, residential, and mountainous. Sequencing 16S rRNA amplicon fragments used to analyze the soil bacterial community. It was discovered that Proteobacteria, Actinobacteria, and Firmicutes comprised the majority of the bacterial community. In addition, the samples contain a high relative abundance of Bacillus, Bradyrhizobium, Chryseobacterium, Cystobacter, Microvirga, and Burkholderia. The high alpha diversity indexes suggest that the agricultural soil microbiome provides important ecological services and may harbor a wide variety of bacteria and genes with biotechnological applications. The physicochemical soil characteristics are also correlated with the bacterial community structure. The findings can be used to develop bioremediation strategies that employ native microbes to clean and restore agricultural soil contaminated with OPPs.

Abstract

Winongo, Gajah Wong, dan Code adalah tiga sungai yang melintasi Yogyakarta. Banyak industri yang membuang limbah ke ketiga sungai ini, sedangkan Cr adalah logam berat yang banyak terdapat pada limbah industri. Berbagai penelitian telah dilakukan untuk melihat potensi fitoremediasi Cr, tetapi umumnya pada limbah cair industri, bukan pada perairan langsung. Tujuan penelitian ini adalah mengidentifikasi logam berat Kromium (Cr) di ketiga sungai serta potensi fitoremediasinya. Sampel air dan sedimen diambil dari hulu, tengah dan hilir, kemudian kandungan Cr dianalisis dengan Spektrofotometri UV-Vis di Laboratorium Kimia Fakultas MIPA Universitas Negeri Yogyakarta (UNY). Untuk melihat potensi fitoremediasinya dilakukan eksperimen dengan eceng gondok (Eichornia crassipes) dan kayu apu (Pistia stratiotes) di greenhouse FMIPA UNY. Pengukuran kualitas air diujikan ke Laboratorium BBTKL-PP. Hasil penelitian menunjukkan ketiga sungai teridentifikasi cemaran Cr tetapi masih di bawah ambang baku mutu menurut Peraturan Gubernur DIY Nomor 20 Tahun 2008 tentang Baku Mutu Air di Provinsi DIY Kelas 1. Potensi eceng gondok dan kayu apu sebagai fitoremediator air sungai yang tercemar Cr tidak tampak jelas karena konsentrasi Cr pada ketiga sungai masih rendah di bawah ambang baku mutu (<0.05 mg/L), akan tetapi dilihat dari performa tanaman maka kedua gulma ini berpotensi untuk menjadi fitoremediator di sungai yang tercemar Cr.
