Agar wood farmer of Pejaring Village have used traditional method to induce resin formation on agarwood tree. They used mechanical method induction by nail and machete tools as well as chemical method induction by chemical liquid that the called by “infus”. These traditional methods influenced resin formation on agarwood tree at their agarwood plantation. That resin production was low in productivity and low in efficiency. The purpose of this community service was to conducted workshop of bio-induction technology for Pejaring Village agarwood farmer to solve their problem. Agarwood farmer of Pejaring Village were directly involved in all bio-induction training activity. This training was started by socialization of program through FGD with Agarwood Farmer of Pejaring Villange. Practical stage was started by selecting agarwood tree for sample by themselves. After selecting process has been done, training continued by bio-induction of agarwood sample using bore and injecting method also by themselves. The last stage was monitoring and evaluating of resin production on agarwood sample as result of bio-induction. In this stage, they got opportunity to give self-assessment of those resin production by organoleptic test. Bio-induction technology could stimulate resin formation on agarwood tree sample at 3 months after induction. This result was much better comparing to the result of traditional induction method that they used to conducted. Organoleptic test has confirmed that resin has quite good fragrance quality. It could be concluded that Pejaring Village agarwood farmers have understood about bio-induction technique and could applied that technology to replace traditional technology.

ABSTRAKGaharu merupakan komoditas hasil hutan bukan kayu yang bernilai ekonomi tinggi, namun keberadaannya di alam semakin berkurang. Salah satu upaya yang bisa dilakukan untuk mengurangi perburuan gaharu di alam adalah dengan budi daya gaharu. Salah satu usaha budi daya adalah teknik inokulasi menggunakan teknik simpori, yaitu metode inokulasi modifikasi menggunakan Fusarium solani dan paku berpori. Penelitian ini bertujuan untuk mengetahui pengaruh dosis inokulan F. solani pada kuantitas dan kualitas gaharu Gyrinops versteegii hasil inokulasi dengan teknik simpori. Penelitian ini menggunakan teknik inokulasi simpori dengan rancangan acak lengkap dengan 3 perlakuan dan 10 ulangan. Perlakuan yang dicobakan adalah dosis inokulan F.solani 3 mL/paku simpori (P0), dosis inokulan 9 mL/paku simpori (P1), dan dosis inokulan 6 mL/paku simpori (P2). Gaharu dipanen pada saat 7 bulan setelah inokulasi awal, diukur dimensi pembentukan dan rendemen produksi gaharu serta dianalisis kandungan kimianya menggunakan GCMS. Hasil penelitian menunjukkan bahwa dimensi pembentukan dan rendemen produksi gaharu tidak berbeda nyata pada semua perlakuan. Panjang pembentukan gaharu tertinggi dicapai oleh perlakuan P1, yaitu mencapai 5,1 cm. Kedalaman pembentukan gaharu tertinggi dihasilkan oleh perlakuan P0, yaitu sebesar 7 cm. Rendemen produksi gaharu tertinggi mencapai 0,032% dihasilkan oleh perlakuan P1 dan P2. Kualitas gaharu pada semua perlakuan secara visual (SNI 7631:2011) adalah sama, yaitu kemedangan TG.C. Kualitas gaharu dilihat dari kandungan sesquiterpene dan chromone derivative pada ketiga perlakuan berbeda. Kandungan tertinggi dihasilkan oleh perlakuan P2 sebesar 17,5%. Pemberian dosis inokulan F. solani yang berbeda menghasilkan gaharu dengan kuantitas sama namun kualitasnya berbeda pada saat 7 bulan setelah inokulasi awal.

Beekeeping is one of the excellent businesses for people around the forest. To date, the bee species that began to broaden are stingless bees. Tetragonula spp. is a stingless bee species in Lombok that have been promoted. This research aim is to determine the characteristic of stingless beekeeping products in Lombok. The meliponiculture products of Tetragonula spp. consist of honey, beebread, and propolis. SNI 3545 was used to examine the honey characteristic of Tetragonula spp., the proximate analysis was performed for beebread products and phytochemical analysis was used to stingless bee propolis products. The results showed that stingless bee honey has a value that fulfills 65% standard, the diastase enzyme was <3 DN and acidity was < 200 ml NaOH/kg. The average content of moisture, ash, protein, fat, and carbohydrates from bee bread were 24, 2, 15, 9.5, and 49% respectively. The phytochemical analysis results of propolis determined that all samples contain flavonoids, tannins, saponins. Several of them positively steroid detected. This study results could be used to considerate further research related in manufactured final products of stingless bee products as raw materials.

Carbon dioxide (CO2) pollution occurs due to the increasing of fossil fuels usage for industry and transportation. Due to the deforestation, the absorption of CO2 by plants is reduced ABSTRAKPencemaran karbondioksida terjadi karena peningkatan penggunaan bahan bakar fosil untuk industri dan transportasi. Akibat terjadinya deforestasi, penyerapan karbondioksida oleh tumbuhan terrestrial berkurang, sehingga terjadi peningkatan penyerapan karbondioksida oleh laut. Penyerapan karbondioksida oleh laut akan menyebabkan perubahan sifat kimia laut yang berdampak pada ekosistem laut. Spirulina platensis sebagai organisme kosmopolitan yang terdapat di laut dapat menggunakan karbon anorganik yang terserap dalam laut. Penelitian ini bertujuan untuk mempelajari efek laju karbondioksida terhadap morfologi dan laju pertumbuhan populasi Spirulina platensis. Metode penelitian ini adalah rancangan acak lengkap dengan tiga perlakuan dan tiga ulangan. Masa perlakuan dimulai pada fase eksponensial dengan laju karbondioksida 0,1 lpm, 0,2 lpm, dan 0,4 lpm. Hasil penelitian menunjukkan bahwa karbondioksida yang diberikan mampu digunakan oleh S. platensis untuk meningkatkan pertumbuhan tetapi juga akan memperpendek kinetika pertumbuhan. Hal ini juga tercermin pada hasil analisis statistiknya yang tidak ada beda nyata (p>0,005). Secara morfologi, respon S. platensis terhadap pemberian karbondioksida menunjukkan terjadinya fragmentasi dan lisis sel.Kata kunci : karbondioksida, Spirulina, laju pertumbuhan, morfologi 1 2

These research objectives were to identify the honey type and the potential plants as food source of stingless bees in Lombok, West Nusa Tenggara. Stingless bees honey samples were collected on September 2016 from four different locations in Lombok which are North Lombok, West Lombok, Central Lombok, and East Lombok. The pollen analysis was performed using Von Der Ohe et al. (2004) methods with modification. The result showed that stingless bees honey samples from four locations did not have predominant pollen which classified as multifloral honey. Meanwhile in the honey samples there identified 27 pollen types belonging to 21 families. The pollen spectrums of honey samples were diverse, with the highest dominancy of Arecaceae (Cocos nucífera) in North and Central Lombok and also Tiliaceae (Type Tílíaceae) in West and East Lombok.
