Budidaya tanaman buah naga mulai berkembang di Indonesia sejak tahun 2003. Hingga saat ini, penyerbukan di kebanyakan perkebunan masih dilakukan secara buatan. Perbedaan perilaku serangga menjadi hal penting yang dapat menentukan kesuksesan penyerbukan alami. Keberadaan serangga lokal diduga dapat menjadi agen polinator yang dapat mengurangi aktivitas penyerbukan buatan pada bunga buah naga. Penelitian ini dilakukan untuk mengetahui karakteristik perilaku serangga yang berpotensi menjadi agen penyerbuk alami buah naga. Kata kunci: perilaku, serangga, Hylocereus undatus

Pada tahun 1998, kecamatan Cineam di kabupaten Tasikmalaya, Jawa Barat, mengalami Kejadian Luar Biasa (KLB) malaria dengan jumlah kasus mencapai 800 kasus sehingga Pusat Kesehatan Masyarakat (PUSKESMAS) kecamatan Cineam berada pada stratifikasi High Case Incidence (HCI). Kondisi berbeda terjadi pada tahun 2009 dan 2010 dimana jumlah kasus yang terjadi adalah 15 dan 6 kasus, secara berurutan. Penelitian ini bertujuan untuk melakukan analisis terhadap faktor-faktor yang menyebabkan KLB malaria tahun 1998. Metoda pengambilan data dengan (1) pencuplikan nyamuk Anopheles menggunakan CO2 Trap di 5 dari 10 desa pada kecamatan Cineam untuk mengetahui populasi nisbi dari nyamuk vektor malaria dan (2) wawancara dengan petugas pemberantasan penyakit menular (P2M) yang bertugas pada PUSKESMAS kecamatan Cineam saat KLB pada tahun 1998. Hasil yang diperoleh pada penelitian ini, dari 320 individu nyamuk Anopheles yang ditangkap, terdapat empat jenis nyamuk Anopheles dengan tingkat dominansi, Anopheles vagus (33,13%), Anopheles aconitus (28,75%), Anopheles barbirostris (23,75%), dan Anopheles kochi (14,38%) dimana hanya An. aconitus dan An. barbirostris yang merupakan vektor malaria. Keberadaan nyamuk Anopheles ini didukung oleh faktor klimat serta keadaan lingkungan setempat yang menyediakan feeding place, resting place, dan breeding site bagi nyamuk Anopheles. Walaupun demikian, keberadaan populasi nyamuk Anopheles bukan merupakan faktor utama penyebab KLB malaria, melainkan rendahnya pemahaman masyarakat pada penyakit ini. Hal ini ditunjukkan oleh rendahnya tingkat prevalensi malaria yang sangat rendah (Low Case Incidence) yaitu pada tahun 2009 dan 2010 (sebesar 0,44‰ dan 0,18‰ secara berurutan) setelah dilakukan penanggulangan penyebaran malaria dalam bentuk penyuluhan pada warga sejak KLB pada tahun 1998.

Black soldier fly (Hermetia illucens) is one of the biological agents for organic waste decomposition. This process produced insect biomass with significant economic value. To maintain the population of this insect, an artificial rearing had to be done to produce a continuous supply of eggs. One of the important components of egg production is substrate to attract female to lay egg on the ovitraps. Ovitrap is a structure applied to accumulate the egg for easier handling. In this study, the preference of female on the several types of attractants was tested. The subtrates were rotten cabbage, rotten papaya, tofu dreg, and commercial fish feed. The preference was based on the amounts of eggs laid on the ovitrap (in weight). The result showed that fish mill is the most preference substrate (amount of eggs: 2.17 gram) while tofu dreg was the least preferred substrate (amount of eggs: 0.06 gram).

One main drawback of the local animal industry is the inavailability of affordable and sustainable protein supply for the livestock. Insect larvae, such as the Black Soldier Fly (Hermetia illucens) larvae (BSFL), have been considered as a protein source which can be produced at a large scale using low cost organic wastes as feeding material. This study was designed to determine the response of BSFL to various waste combinations of vegetable and animal remains, Pak Choi (Brassica chinensis) residues (S) and carp (Cyprinus caprio) fish offal (I)). A total of 540 BSFL were fed with 100 mg/larvae/day combination of vegetable wastes: animal waste 70%: 30% (S > I), 50%: 50% (S = I), and 30%: 70% (S < I). Among the feed combinations, the S < I group showed the best results as it produced the significantly highest weight of BSFL at 122.8 mg/larvae and approximate digestibility of 62.01%, with the least pupae mortality rate at 4.29%.Keywords: bioconversion, biomass, Brassica chinensis, Cyprinus carpio, Hermetia illucen

The application of seed for true shallot cultivation is an alternative of the more common cultivation practice, in which 30% of harvested tubers used for cultivation purposes. The seed production of this temperate tuber, in the tropical region, is quite challenging due to low flowers and seed formation. Several studies showed that vernalization (cold induction) and application of Benzil Amino Purin (BAP) could be applied to improve flowering and seed production. However, such studies were conducted during the best cultivation period for about 3 months and thus, limit the production period of seeds. This study was conducted to observe the effect of both methods outside cultivation periods to flower and capsule numbers, fruit set, and weight of 100 seeds compared with common cultivation. In this study, bulbs of onion vernalized at 10oC for 30 days then became subjected to synthetic hormone (BAP) prior planted while control group The results showed that BAP treated shallot group has the lowest values for all observed parameters (1552.67, 312.11, 22.5%, 0.2244 gram) compared to those vernalization treated group (1592.44, 623, 30.5%; 0.2261 gram) and control group (6774.67; 3898.44; 57.06%; 0.3304 gram). Based on this study, it could be concluded that common cultivation is a better method to produce true shallot seeds during the offseason.

One of the materials with great potency for future nutrition source for animal feed is prepupae of black soldier fly larvae (BSFP) (Hermetia illucens) which is fed on organic wastes. This study was designed to observe the accumulation of specific substance (omega-3) of organic wastes (marine fish offal and tofu dregs) inside harvested biomass of BSFP. A total of 150 gram food consist of marine fish offal and tofu dreg with different proportion (10:90, 25:75, 50:50, and 100% tofu dregs) was fed to black soldier fly larvae (BSFL) for 21 days.At the end of feeding trial, all BSFL were harvested, weighed, and then analyzed for omega-3 fatty acids content. Fatty acid content was analyzed using Gas Cromatography with Flame Ionization Detector (GC-FID). Result of the experiment showed BSFL reared with 25% marine fish offal produced highest biomass (8.1 g / 50 larvae) with least development time (19 days). The total of omega-3 recorded from application of 0%, 10%, 25%, and 50% of marine fish offal was 0.02%, 0.87%, 2.16% and 2.61% in 100 g of dry weight, respectively. This result showed the possibility of transferring specific nutrient from organic wastes biomass of BSFP which provides base knowledgement for further application in design of specific animal feed from BSFP.

This study aimed to determine the efficiency of the use of propolis as a biocoating for post-harvest bananas in order to extend shelf life. This study used local banana that typical in Indonesia, Moss banana (Musa acuminata) and the propolis bee Trigona laeviceps, which is also produced by local agriculture, with a concentration of application 5%, 10%, 15%, coating using 70% ethanol as a positive control, and bananas without coating as a negative control. Observation parameters that measured are weight loss, pulp to peel ratio, size, color, fruit temperature, cell death, fruit firmness, total soluble solid (TSS), sucrose content, vitamin C, and potassium content on days 0, 3, 6, 9, 12, 15, 18 and 21 after coating. The results showed that coating using 5% propolis significantly extend the shelf life compared to the control by slowing the increase in fruit maturity index (color), weight loss, size loss, pulp to peel ratio, fruit temperature, pulp softening, and increased levels of vitamin C. Treatment process itself does not have a significant effect on changes in the value of TSS and sucrose during the storage period.Keywords: propolis, moss banana, post-harvest protection.

Studies showed that cross-pollination also affect fruits and green bean coffee quantity and quality yet study on this subject in Indonesia rarely found. This study focused on assessing the pollination effect of fruit quality and beans in terms of size, weight, physical defect, and content of caffeine and fatty acid. During this study, Tetragonula laeviceps, indigenous stingless bees, were applied as a pollination agent to be compared to open pollination. The result showed that open pollination produced bigger beans (16.73abÂ±1.57 X 14.66aÂ±1.48 mm) with higher caffeine (18.22%) and lower fatty acid (41,86%), while application of T. laeviceps produced slightly heavier beans (0.22 gram). Besides producing higher caffeine and lower fatty acid, cross-pollination services mainly required wild pollinators, although T. laeviceps could act as a potential replacement or for the inundation of this service.
