Abstract. Rusmini, Manullang RR, Daryono. 2017. Development of shrimp shells-based compost and plant-based pesticide using bioactivators from Golden Apple Snails and their effects on the kenaf plant growth and pest population. Nusantara Bioscience 9: 260-267. Kenaf (Hibiscus cannabinus L) cultivation generally uses chemical fertilizers and pesticides to increase production despite the adverse effects of those chemicals toward environmental ecosystem. Meanwhile, there are a lot of unutilized wastes produced from agriculture and fishery. This study aimed to develop the best bio-activator from Golden Apple Snails and spices to decompose the shrimp shells waste. The bioactivator was utilized for the production of plant-based pesticide to control pests in kenaf plant, and shrimps-shells-based composts to improve kenaf plant growth. This study employed a Randomized Block Design with two factorials. The first factor was the shrimp shells-based composts (K) which consist of three levels, and the second factor was the plant-based pesticide (P) which also consists of three levels. Each of experiment was repeated twice. Thus, in total there were 18 treatments. The shrimp shells-based composts had a pH value of 8.79, Potassium (K) 8.13 %, organic carbon (C) 17.45%, Nitrogen (N) 3.62%, Phosphorus (P) 2.27%; Magnesium (Mg) 0.59%, and Calcium (Ca) 7.64%; and a C/N ratio of 4.82. Kenaf plant height at 6 and 9 weeks after planting (WAP) showed significant differences upon the shrimp shells-based composts treatments. At 6 weeks after planting, kenaf plant diameter showed significant differences upon the composts treatment, while at 9 weeks after planting, the plant diameter indicated significant differences upon both the compost and plant-based pesticide applications. Pest populations that were present in kenaf plants were caterpillars, bugs, and beetles.
Keong mas merupakan hama bagi tanaman padi tetapi dapat dijadikan sebagai bioaktivator. Bioaktivator keong mas sebelumnya hanya mengandung bakteri Pseudomonas flourescens dan kandungan unsur hara masih rendah. Rumen kambing merupakan limbah dari peternakan yang kebanyakan malah menjadi limbah yang mencemari lingungan. Penelitian ini bertujuan untuk meningkatkan kualitas bioaktivator keong mas yang dikombinasikan dengan rumen kambing baik dari sifat fisik, kandungan unsur hara dan jenis mikroorganisme. Penelitian terdiri dari dua perlakuan yaitu pembuatan bioaktivator keong mas dengan penambahan rumen kambing cair (r1), dan pembuatan bioaktivator keong mas dengan penambahan rumen kambing padat (r2). Pembuatan bioaktivator keong mas dengan penambahan rumen kambing dengan cara difermentasi selama 18 hari. Sifat fisik bioaktivator keong mas dengan penambahan rumen kambing cair dan padat diamati mulai dari awal pembuatan bioaktivator keong mas sampai jadi. Uji analisa kimia bioaktivator keong mas meliputi pH, dan kandungan unsur hara makro N, P dan K dan uji analisa kandungan bakteri. Hasil penelitian menunjukkan bahwa sifat fisik bioaktivator keong mas kombinasi rumen kambing hasil analisis unsur hara N, P, dan K untuk kedua perlakuan bioaktivator keong mas denga Hasil penelitian menunjukkan bahwa sifat fisik bioaktivator keong mas kombinasi rumen kambing lebih baik karena telah jadi pada hari ke-18, kandungan unsur hara bioaktivator keong mas kombinasi rumen kambing pada kedua taraf perlakuan meliputi unsur N, P, dan K sudah memenuhi standar Pupuk Permentan No.28 Permentan/SR.130/5/2009 dan peningkatan jumlah bakteri sebanyak 7 jenis pada taraf perlakuan r1 dan 8 jenis pada taraf perlakuan r2.
The production of kenaf fiber for industry mostly uses chemical fertilizers with synthetic dyes which will also cause health and environmental problems and have an adverse effect on all forms of life. Increasing awareness of health and the environment makes the production of organic kenaf fiber with natural dyes highly recommended both for handicrafts and for industrial scale because fertilizers and natural dyes are non-toxic, biodegradable, and environmentally friendly. The purpose of this study was to determine the level of consumer preference for organic kenaf fiber with natural dyes. The study used a twofactor randomized block design with the first factor of organic kenaf fiber and the second factor of natural dyes consisting of 4 levels. The study was repeated as many as 2 replications so that there were 10 experimental units. Variables observed in the level of consumer preference for handicraft products from organic kenaf fiber with natural dyes which include colour, texture and odor are tested. This test was carried out by the Hedonic Test method, using a questionnaire with 40 untrained (consumer) panellists with data obtained based on panellist responses using the hedonic scale analysed by the Kruskal-Wallis test. The results showed that there were no significant differences in the level of consumer preference for colour, texture and odor from organic kenaf fibers with various natural dyes.
Tebing lonceng atau lebih dikenal dengan sebutan gunung lonceng merupakan obyek wisata dengan mengandalkan pemandangan Kota Samarinda dilihat dari atas. Sehingga wisatawan umumnya menikmati obyek wisata ini pada subuh atau malam hari karena hamparan Kota Samarinda dapat dilihat hampir 360o. Sayang sekali tebing ini tanahnya tandus dan tidak subur sehingga wisatawan enggan untuk datang di siang hari, karena panas dan terik. Disamping itu tempat wisata ini pengelolaanya kurang maksimal tidak memiliki gapura, pagar pembatas, nama jalan dan lokasi, tidak memiliki alat pemadam kebakaran ringan tanaman bungapun ditanam sekedarnya. Pada kegiatan pengabdian ini melakukan perbaikan dan peningkatan sarana dan prasarana yang ada, pemupukan, penanaman tanaman bunga dan buah, pemberian dan pelatihan penggunaan APAR. Kegiatan ini dilakukan dari Bulan Agustus 2021 sampai dengan September 2022. Hasil yang diharapkan nantinya tempat wisata ini menjadi agrowisata tidak hanya mengandalkan tempat selfie tetapi juga menjadi wisata tanaman buah baik di siang maupun malam hari. Tebing lonceng menjadi wisata taman dengan tanaman buah dan bunga dengan sarana dan prasarana yang memadai, jumlah pengunjung meningkat terutama di siang hari dan pendapatan mitra juga meningkat.

Variables observed by consumer's level of craft product from organic kenaf fiber with natural dye covering color, texture and odor tested. This test is done by Hedonic Test method, using questionnaire with untrained panelist (consumer) as many as 40 people with data obtained based on a panelist response using a hedonic scale was analyzed by Kruskal-Wallis test. The results showed that there was no significant difference in consumer preferences for the color, texture and odor of organic kenaf fiber with various natural dyes.
