ABSTRAKPenyakit kerdil merupakan salah satu penyakit penting padatanaman lada (Piper nigrum L.), yang disebabkan oleh dua jenis virus,yaitu Piper Yellow Mottle Virus (PYMV) yang ditularkan oleh kutu putih(Planococcus minor dan Ferrisia virgata); dan Cucumo Mosaic Virus(CMV) yang pernah dilaporkan ditularkan oleh Aphis gossypii. Penelitiantentang penyakit ini telah dilakukan di laboratorium dan rumah kaca untukmengetahui kemampuan serangga vektor P. minor, F. virgata dan A.gossypii dalam menularkan penyakit. Serangga tersebut diberi makanselama 24 jam pada tanaman lada yang terserang penyakit kerdil,kemudian serangga dipindahkan ke bibit lada sehat selama 24 (A. gossypii)dan 48 jam (P. minor dan F. virgata). Pada setiap jenis serangga diuji 1, 3,7 dan 10 ekor per tanaman. Dengan cara yang sama dilakukan pulapengujian lanjutan penularan dengan A. gossypii (sebanyak 10 ekorserangga per tanaman) dengan menggunakan tiga sumber tanaman sakityang berbeda (tanaman sakit asal Bangka, asal Sukabumi dan Bogor).Selain itu dilakukan penularan secara mekanik dengan menggunakanketiga sumber inokulum. Tanaman yang telah diperlakukan diinkubasikandi rumah kaca. Deteksi virus dilakukan dengan ELISA denganmenggunakan antiserum dari Agdia. Hasil penelitian menunjukkan bahwaP. minor dan F. virgata dapat menularkan penyakit kerdil ke tanaman ladahingga 100%, sedangkan penularan dengan A. gossypii tidak menunjukkangejala, tetapi pada pengujian lanjutan dengan A. gossypii memperlihatkanbeberapa tanaman bergejala. Dari penelitian ini terungkap kutu putihmerupakan serangga vektor PYMV yang sangat efisien, sedangkan A.gossypii dapat berperan sebagai vektor CMV dengan kemampuanpenularan masih terbatas.Kata kunci : Piper nigrum L., penyakit kerdil, Ferrisia virgata,Planococcus minor, Aphis gossypii, CMV dan PYMV,penularanABSTRACTTransmission of stunted growth disease on black pepperby three insect vectorsStunted growth disease is one of the most important diseases onblack pepper caused by Piper Yellow Mottle Virus (PYMV) transmitted byMealybugs (Planococcus minor and Ferrisia virgata) and Cucumo MosaicVirus (CMV) transmitted by Aphis gossypii. These experiments wereconducted at laboratory and green house to examine the capability of theinsects in transmitting the disease. The insects were fed on black pepperplant for 24 hours, then transferred to healthy black pepper seedlings for24 hours (A. gossypii) and 48 hours (P. minor and F. virgata). Each plantwas treated with 1, 3, 7 and 10 insects. Other disease transmission test withA. gossypii was carried out using the similar method, but each plant wastreated with 10 insects and used three source plants (disease plant fromBangka, Sukamulya/Sukabumi and Bogor). Disease mechanicaltransmission was also carried out to black pepper plant using the threesources of disease plant treated plants were incubated in the glass house.ELISA was used for disease confirmation with antiserum from Agdia.The results showed that high transmission rate (up to 100%) were obtainedin transmission with P. minor and F. virgata . No disease symptoms wereshown in black pepper seedlings treated with A. gossypii. In the othertransmission test, however, some plants showed symptoms. The similarsymptoms were also seen on black pepper plants which were mechanicallyinoculated. The ELISA showed that the plants were positive for CMV.These experiments suggested that P. minor and F. virgata are veryefficient vectors for PYMV, Whereas A. gossypii was confirmed as vectorof CMV of black pepper with limited ability in transmitting the disease.Key words : Black pepper, stunted growth disease, Ferrisia virgata,Planococcus minor, Aphis gossypii, CMV, PYMV,transmissio

Zero waste agriculture is an agricultural concept oriented around the decomposition cycle of organic materials which integrates agricultural and livestock systems to reprocess waste material. Agricultural waste is used as animal feed while livestock waste/excrement is reprocessed into organic fertilizers. The Regional Partnership Service Program (PKW) aims to assist farmers in developing integrated farming businesses based around zero waste agriculture. PKW was held between May and July 2021 in Tindaki Village, South Parigi District, Parigi Moutong Regency. The implementation of this regional partnership program was carried out through a Participatory Action Programs approach, where partners are directly involved in the adoption and application of the various skills that had been developed. The procedure for activity implementation was carried out through several stages, namely: (a) counseling on zero waste agriculture, (b) training in and application of zero waste agriculture technology in the form of demonstration plots for the application of technological products, (c) coaching and mentoring, and (d) the utilization stage of technology product. The findings from the implementation concluded that the agricultural development training based on zero waste agriculture was a success, and the technology had been adopted by the community, marked by the ability to make and develop compost and liquid organic bio-urine fertilizers. Both types of organic fertilizers had been applied in the demonstration plots to assess their effectiveness in reducing the use of inorganic fertilizers. Rice production is equivalent to 5.6 tons/ha and 6 tons/ha in conventional land. These results show potential benefits for farmers, particularly regarding lower production costs compared to the usage of conventional land. Zero waste agriculture is a method of farming and livestock raising that utilizes their waste products for energy production.

Aspergillus niger produces α-amylase and glucoamylase enzymes whichenable starch to be broken down into simple glucose then fermented into ethanol. The growth of A. niger is directly related to food substances within the medium. A. nigeralso generatessuch enzymes as amylase, amyloglucosidase, pectinase, cellulose, glycoside that can break down urea into amino acid and CO2. The research objective was to find A. Niger fungi isolate which potentially has antagonist characters against the growth of P. Palmivora fungi in cacao fruits. The research was conducted in the Pest and Disease Laboratory, Faculty of Agriculture of Tadulako University from September to December 2015. The research results showed that 20 isolates of A. niger found are potentially utilized as biological control agents of fungal antagonist against P. Palmivora in four villages where cacao are produced i.e. Sidondo, Lalundu, Towiora and Martajaya. The results of in-vitro inhibition test suggested that two isolates best in suppressing the growth of P. Palmivora causing cacao fruit rot are Lalundu isolates (rate of inhibition of 63.65%) and Martajaya isolates (rate of inhibition of 63.63%)Key Words: Aspergillus niger, fungi, antagonis, Phytophthora palmivora.

The tendency of more intensive use of chemicals in agricultural cultivation activities causes an imbalance of other nutrients and decreases the content of soil organic matter. This causes degradation of soil fertility and residues of active pesticides that threaten the sustainability of farming. The community partnership program (PKM)aimed to provide solutions to problems faced by partners in both the production and management fields by providing counseling, demonstrations and assistance. The method activities is participatory rural appraisal (PRA) in applying appropriate technology and empowerment, with partners in these activities being members of the "Batu Sari" farmer group in Astina Village, Torue District, Parigi Moutong Regency. The results of the implementation of community partnerships show an increase in knowledge and skills and attitudes of farmers. The production of organic fertilizers, vegetable pesticides and bioinsecticides carried out by the activity participants went well and could be used as expected. The system of rice intensification (SRI) cropping system can be implemented by partner farmers. partner farmer groups become independent in carrying out their farming activities using assembled technology that has been practiced

UPT Bulupountu Jaya is the one of many shallots or red onions and other vegetables production center in Sigi Regency. The farmers rely heavily on pesticide and chemical fertilizer in their business. Even, the residual pesticide on the plant is beyond permitted standard. The main factor is the lack of awareness and skills of the farmers towards environment-based cultivations and pest control. Our community service with regional featured product schematics, aim to spread the information about the technology of formulation and application of Plant Growth Promoting Rhizobacteria (PGPR) as biofertilizer and bioprotectant on red onion plantations. The methods that were going to be implemented, there are training, demonstration plot of technology application, and assistances. The result of our community service, shows that participants are really into this daily program in the moment, shown by the activeness of participants at various stages of activity. This program of our community service increases the farmers skill points to create own PGPR. For the clearest, about 70% participants increased their knowledge and skill to create PGPR and about 60% participants have had interest to develop and apply PGPR as biofertilizer. As doing so, we expect independent of the farmers from being rely on chemical inputs on red onion plantations.
