Abstract

Coffee is a commodity with high value for export. Coffee bean borer (Hypothenemus hampei) is the main pest causing the decline in coffee production. Farmers still rely on chemical insecticides to control this pest. To reduce the negative impact of insecticides, entomopathogen Beauveria bassiana is applied. The research aimed to investigating the level of pathogenicity of B. bassiana in controlling H. hampei, and investigating the concentration with the highest level of pathogenicity of B. Bassiana against H. hampei. Laboratory research was arranged in one factor Completely Random Design (CRD). This research used 8 (eight) treatments namely KO: Aquades, Kk: Lamda Sihalothrin 25 EC (Chemical Insecticide), B1: 10 g / L B. bassiana cultivated in rice bran media, B2: 20 g / L B. bassiana cultivated in rice bran media, B3: 30 g / L B. bassiana cultivated in rice bran media, B4: 10 g / L B. bassiana grown on corn media, B5: 20 gL B. bassiana grown on corn and B6: 30 g / L B. bassiana grown on corn media. Each treatment used coffee beans infested with 20 H. hampei and repeated 4 (four) times. The result of the research showed that B. bassiana was able to kill H. hampei. The concentration that was able to cause the fastest mortality with a high level of pathogenicity based on the pathogenicity test of B. bassiana on H. hampei (percentage of mortality, total mortality time, and feeding capacity) was 30 g/L of B. bassiana cultivated in rice bran media.Key words: Beauveria bassiana, Hypothenemus hampei, chemical insecticide, coffee bean

Abstract

Synthetic insecticides have detrimental effect to environment. Botanical insecticides are considered to be safer to the environment. Need seeds contain compounds with insecticidal properties. The aim of this study was to examine the effectiveness of neem seeds extract to control Diamondback moth (DBM). A series of neem seeds extract concentration (0.04 %, 0.08 %, 0.16 %, 0.32 %) and control (without neem extract) were tested on second instar larvae in oral test and contact test. The results showed that neem seeds extract have significant effect on the mortality of second instar DBM larvae 24-72 h after treatment in oral test and 72 h after treatment in contact test. In the oral test, the neem seeds extract significantly reduced feeding intensity of the larvae 42 h and 72 h after treatment. Subsequently, the extract also significantly reduced the moth emergence. The neem seeds with concentration 0.16 % effectively control DBM second instar larvae 72 h after treatment.Key Words: neem seeds extract, diamondback moth, effectiveness

Abstract

UKM Sarabba Rajana memproduksi Sarabba instant, minuman tradisional khas Sulawesi Selatan. UKM Sarabba Rajana terletak di Luwu Utara yang berjarak sekitar 500 km dari Makassar ibu kota Provinsi Sulawesi Selatan. UKM ini belum berkembang karena jauh dari pusat bisnis Sulawesi Selatan dan produknya belum dikenal dan mampu bersaing secara regional. Pada tahun 2021 tim pengabdian kepada Masyarakat (PKM) UPN “Veteran” Yogyakarta menyelenggarakan kegiatan penyuluhan, pelatihan, pengembangan merek, adaptasi mitra pada teknologi, pembentukan dan pengembangan jejaring untuk UKM ini. Pelaksanaan pengabdian dilakukan dengan mengkombinasikan berbagai metode PRA (Participatory Rural Appraisal), PLA (Participatory Learning Action) untuk meningkatkan kapasitas mitra. Dampak PKM pada UKM ini adalah  produk yang marketable,  produk terstandarisasi sesuai regulasi pemerintah,  brand Sarabba Rajana dikenal secara luas,  penetrasi pasar yang kuat sehingga menjadi oleh-oleh khas Makassar. Selain itu, pemerintah kabupaten Luwu Utara menyatakan UKM ini berpredikat unggul sehingga dapat menjadi model keberhasilan UKM.
EFEKTIFITAS Trichoderma harzianum YANG DIPERBANYAK PADA BERBAGAI MEDIA DAN WAKTU APLIKASI BERBEDA UNTUK PENGENDALIAN Colletotrichum spp. PADA BUAH CABAI Endah Paramita Pratiwi; R.R. Rukmowati Brotodjojo; Chimayatus Solichah

Abstract

Cabai merupakan salah satu komoditas yang bernilai ekonomi tinggi di Indonesia. Budidaya cabai dihadapkan pada penyakit tanaman yang salah satunya yaitu penyakit antraknosa yang disebabkan oleh Colletotrichum spp. Upaya pengendalian dengan Trichoderma harzianum diharapkan mampu menekan serangan patogen Colletotrichum spp. Penelitian ini bertujuan untuk mengetahui media T. harzianum yang terbaik dan waktu aplikasi yang tepat dalam mengendalikan Colletotrichum spp. Penelitian dilaksanakan di Laboratorium Proteksi Tanaman UPN “Veteran” Yogyakarta pada bulan Januari–April 2022. Rancangan yang digunakan yaitu Rancangan Acak Lengkap (RAL). Pada penelitian in-vitro digunakan 4 perlakuan media yaitu dedak, jagung, air kelapa, dan limbah cair tempe serta 1 perlakuan kontrol Colletotrichum spp. tanpa agen hayati.  T. harzianum dari media perbanyakan yang efektif pada uji in-vitro, dilakukan uji lanjut in-vivo  dengan perlakuan kontrol (tanpa fungisida dan agen hayati), Fungisida Propineb, T. harzianum sebelum inokulasi patogen, dan T. harzianum setelah inokulasi patogen. Parameter yang diamati pada uji in-vitro adalah persentase penghambatan (%) dan pada uji in-vivo adalah masa inkubasi (hari), kejadian penyakit (%), intensitas penyakit (%), dan AUDPC. Data yang diperoleh dianalisis dengan uji F ANOVA apabila hasil menunjukkan perlakuan berbeda  nyata kemudian dilakukan uji lanjut menggunakan Uji Jarak Berganda Duncan taraf 5%. Trichoderma harzianum yang diperbanyak pada media dedak efektif menekan patogen Colletotrichum spp. pada uji in-vitro, serta waktu aplikasi T. harzianum sebelum inokulasi patogen sama efektifnya dengan aplikasi T. harzianum setelah inokulasi patogen.

Abstract

Climate change presents serious threats to highland agricultural areas such as Dieng (Central Java) and Karo (North Sumatra), where farmers increasingly experience irregular weather patterns, prolonged droughts, and frost events (bun upas). This study examines how the government communicates climate adaptation innovations—particularly through the Farmer Field School (Sekolah Lapang, SL) program and the work of agricultural extension officers (Penyuluh Pertanian Lapangan, PPL)—to support farmers in these vulnerable regions. Innovations such as the application of Lactic Acid Bacteria (LAB), Plant Growth-Promoting Rhizobacteria (PGPR), and basic frost prevention strategies have been introduced since 2022 through Farmer Field School (SL) initiatives led by local agricultural departments. Guided by Rogers’ Diffusion of Innovation Theory, this qualitative research involved semi-structured interviews with six farmers and two Agricultural Extension Officers. The analysis focuses on five diffusion stages: knowledge, persuasion, decision, implementation, and confirmation. The findings show that while farmers in both regions are increasingly aware of climate change (knowledge stage), many receive information from peers or media rather than official channels. In Dieng, adoption is constrained by resource competition with tourism and limited frost response strategies. In Karo, although media use is higher, government messaging still lacks practical, region-specific guidance. The study reveals key gaps in the persuasion and implementation phases, suggesting that existing communication efforts remain too generic and insufficiently persuasive. It recommends more localized, trust-based, and multi-channel communication strategies tailored to the unique environmental conditions of each region. The research contributes to the understanding of how institutional communication can better support innovation adoption in climate-vulnerable farming communities.
