Abstract

Agricultural development since the last two decades has been mainstreamed to a more environmentally friendly perspective. Cisondari is a village known for applying environmentally friendly practices in their agriculture. In this globalization era, urbanization is inevitable, especially for rural youths. This situation has impacted agricultural workforce structure in the rural area, threatening its future agriculture. However, Cisondari shows an anomaly condition. Cisondari’s agricultural development is highly influenced by the active presence of rural youths. This study aims to identify the determinants of the rural youths’ participation in Cisondari’s agricultural development. The study applies quantitative methods through descriptive statistics analysis. Data were gathered by structured interviews to respondents selected by simple random sampling technique. The results show that the determinants of youths staying in the village are motivation, innovation, and environmental factors. The young farmers are involved in environmentally friendly agricultural practices in many phases ranged from planning, conducting, monitoring, to evaluation.

Abstract

ABSTRACTThe Effects of Three Types of Shade Trees on the Diversity of Insects in Coffee PlantationArabican coffee (Coffea arabica) is one of the plantation commodities that has economic, social, and ecological value in Indonesia. Commonly, coffee is grown in a shaded condition that will affect the diversity of insects. This research was aimed to study the effects of three types of shade trees on the diversity of insects in coffee plants. This research was conducted at Manglayang Peasant Coffee Plantation, Cipulus Village, Cilengkrang Subdistrict, Bandung Regency and the Entomology Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Padjadjaran. The method used was descriptive survey through observation with systematic diagonal method in selected locations based on three types of shade trees, namely suren (Toona sureni Merr), white teak (Gmelina arborea Roxb), and pine (Pinus merkusii Jungh). The results showed that diversity index of the insects of coffee plants in suren shade trees was low to medium, and the highest percentage of abundance was Empoasca sp. Coffee plant diversity index of the insects with white teak shade trees were medium with highest percentage abundance in the Agromyzidae family and Emposca sp. Coffee plant diversity index of the insect with pine shading trees was low to moderate with the highest abundance of Empoasca sp. and Agromyzidae family.Keywords: Shade tree, Diversity, Insect, Coffee plantABSTRAKKopi arabika (Coffea arabica) merupakan salah satu komoditas perkebunan yang memiliki nilai ekonomi, sosial, dan ekologis bagi masyarakat Indonesia. Pada umumnya, kopi ditanam pada kondisi ternaungi sehingga akan berpengaruh terhadap keragaman serangga. Penelitian ini bertujuan untuk mengkaji efek dari tiga jenis pohon penaung terhadap keragaman serangga pada pertanaman kopi. Penelitian dilakukan di Perkebunan Kopi Rakyat Manglayang, Desa Cipulus, Kecamatan Cilengkrang, Kabupaten Bandung dan Laboratorium Entomologi, Departemen Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Padjadjaran. Metode yang digunakan adalah survei deskriptif dengan cara observasi dengan metode diagonal sistematis pada beberapa lokasi yang dipilih berdasarkan tiga jenis pohon penaung, yaitu suren (Toona sureni Merr), jati putih (Gmelina arborea Roxb), dan pinus (Pinus merkusii Jungh). Hasil penelitian menunjukkan bahwa serangga tanaman kopi pada tanaman penaung suren indeks keragamannya rendah sampai sedang, dan persentase kelimpahan tertingginya adalah Empoasca sp. Serangga tanaman kopi dengan pohon penaung jati putih indeks keragamannya sedang dengan persentase kelimpahan tertinggi pada family Agromyzidae dan Emposca sp. Serangga tanaman kopi dengan pohon penaung pinus indeks keragamannya rendah hingga sedang dengan kelimpahan tertinggi Empoasca sp. dan famili Agromyzidae.Kata Kunci: Pohon penaung, Keragaman, Serangga, Tanaman kopi

Abstract

ABSTRACT Potency of Distilled Water of Several Parts of Coffee Plant as Attractant of Coffee Berry Borer (Hypothenemus hampeii Ferr.) in Laboratory Coffee berry borer (Hypothenemus hampeii Ferr.) is one of coffee plant pests, causing fruit damage up to 50 percent. One of control technicques to eliminate the adult female is the use of attractants obtained from parts of coffee plant. The aim of this research was to know the potency of distilled water of parts of coffee plant as attractant to control coffee berry borer. Research was done in the Laboratory of Entomology, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Padjadjaran, from February to July 2015. Experiment was conducted in a Randomized Block Design. The treatments were control without distilled water (P0), coffee exocarp distilled water (P1), coffee berry distilled water (P2), coffee leaves distilled water (P3), and coffee branch distilled water (P4). Each treatment was replicated five times. The result showed that distilled water of coffee plant had a potency as attractant of coffee berry borer. Distilled water of coffee bean at the concentration of 4% had the strongest effect, attracting coffee berry borer of 8.8 female adult. The effectiveness of coffee plant distilled water in attracting coffee berry borer lasted three days. Keyword: Distilled water, Attractant, Coffee berry borer ABSTRAK Penggerek buah kopi (PBKo, Hypothenemus hampei Ferr.) merupakan hama utama tanaman kopi yang dapat menyebabkan kerusakan hingga 50%. Salah satu teknik pengendalian imago betina PBKo yang dapat dilakukan adalah dengan menggunakan senyawa atraktan yang terkandung di dalam bagian tanaman kopi. Penelitian ini bertujuan untuk mengetahui potensi air sulingan bagian tanaman kopi sebagai atraktan terhadap hama PBKo. Percobaan dilakukan di Laboratorium Entomologi, Departemen Hama dan Penyakit Tumbuhan Fakultas Pertanian Universitas Padjadjaran pada bulan Februari 2015 sampai dengan Juli 2015. Metode yang digunakan adalah eksperimen dengan Rancangan Acak Kelompok dengan perlakuan yaitu tanpa pemberian air sulingan (P0); air sulingan kulit buah kopi (P1), biji kopi (P2), daun kopi (P3), dan ranting kopi (P4) dengan konsentrasi masing-masing sebesar 2%, 4% dan 6%. Masing-masing perlakuan diulang sebanyak lima kali. Hasil penelitian menunjukkan air sulingan bagian tanaman kopi berpotensi sebagai atraktan terhadap hama PBKo. Rata-rata jumlah imago betina PBKo terbanyak yang tertarik yaitu pada air sulingan biji kopi pada konsentrasi 4% sebanyak 8,8 ekor betina. Masa aktif dari semua air sulingan yang berperan sebagai atraktan dalam menarik imago betina PBKo yaitu selama 3 hari. Kata kunci: Air sulingan, Aatraktan, Penggerek buah kopi

Abstract

ABSTRACT Treated industrial textile wastewater has organik and heavy metal compound that have toxicity effect on plant and other organism in agroecosystem. This research aimed to study the effect of industrial textile treated wastewater on cabbage growth and oviposition preference of Plutella xylostella L. The research was done at Green House in Ciparanje, Agriculture Faculty, Universitas Padjadjaran, Jatinangor District, Sumedang, West Java, Indonesia on May to June of 2018. Experimental design used was Block Randomized Design with nine treatments of industrial textile treated wastewater in various concentrations: 0%, 12,5%, 25%, 37,5%, 50%, 62,5%, 75%, 87,5%, and 100%, and three replications.

Abstract

Organochlorine pesticide is one of the pesticide that has high persistency and toxic. One of the attempt to degrade organochlorine pesticide using cheaper and easier way is using the slow sand filter technology. The research aimed to test the slow sand filter and to obtain the best filter media combination for degrading organochlorine pesticide. The experiment was conducted at the Laboratory of Pesticide and Toxicology, Laboratory of Plant Protection Biotechnology and Laboratory of Chemical and Soil Fertility, Faculty of Agriculutre, Padjadjaran Univeristy from December 2016 – May 2017. The experimental design used the observative and descriptive design with 8 treatments and repeated twice. P1 (activated carbon and gravel), P2 (sand and gravel), P3 (silica sand and gravel), P4 (activated carbon and zeolite), P5 (sand and zeolite), P6 (silica sand and zeolite), P7 (activated carbon, silica sand and zeolite), P8 (activated carbon, sand and gravel). The result showed that all treatments of slow sand filter were able to degrade organochlorine pesticide and the best filter media combination was from P7 with ability to degrade the pesticide level by 82,86%.Key words: slow sand filter, activated carbon, silica sand, sand, gravel, zeolite
