Abstract

S. litura F pests are widespread in Indonesia covering 22 provinces with an average attack area of 11,163 ha/year.  This pest is polyphag causing damage to the leaves (defoliation) with crop loss can reach 85% even to failed miserably.  The application of biotechnology derived from local resources is a very appropriate alternative to controlling S. litura, namely Bacillus cereus strain ATCC 14579,  Bacillus subtillis subsp. subtilis strain 168  Bacillus siamensis strain KCTC13613, Azotobacter sp. and Pseudomonas fluorescens isolated from the LMO banana stem bud.  The aim of this study is to determine the potential of 5 types of bacteria that were consortified as S. litura pest bio-control agents. The research consisted of stages, namely 1) bacterial compatibility test which would be consortified; 2) invitro bacterial consortium potential test on S. litura F. larvae.  The results showed that the bacteria B. cereus strain ATCC 14579, B. subtillis subsp. Subtilis strain 168 B. siamensis strain KCTC13613, Azotobacter sp. and P. fluorescens are compatible with each other so that they can be consortified. These 5 types of bacteria are single less potential as S. litura pest bio-control agents because they cause low larval mortality, but a consortium of 5 bacteria can cause larval mortality by 70% . Keywords: biocontrol agents, Spodoptera litura, bacterial consortium, LOM banana stem bud

Abstract

Cocoa is one of the many plantation crops cultivated by people in the Subarang Air. Previously, this commodity was quite a trend to be planted by the community. However, it seems that this commodity is not being managed more seriously, so that many smallholder cocoa plantations and plants are no longer producing optimally. Devotion is necessary to provide enlightenment and understanding to women farmer groups in Subarang Air through increasing the capacity of farming communities in managing smallholder plantations. This activity aims to increase the capacity of farmers so that they can increase their insight and knowledge and environmentally friendly agricultural systems for the community so that their land productivity remains high and can be used continuously without causing damage to the land. The methods used in this activity are training and practice. The results obtained from this activity are that farmers are able to participate in every activity carried out and are able to apply knowledge. Keywords: cocoa, Kelompok Tani Wanita, development

Abstract

Cocoa is a plantation crop that is widely cultivated by the community in the Tarantang district, Harau District, both in the form of "parak/fields" and as a plant planted in the shells of residents' homes. However, lately it seems that this commodity is not being managed more seriously, so that many smallholder cocoa plantations and plants are no longer producing optimally. This is due to the general public's lack of knowledge on how to properly cultivate cocoa so that production and quality can be increased. This community service activity aims to motivate and increase the capacity of farmers (farmer groups) so that they can increase their insight and knowledge so that in the future they can help increase the productivity of their farming businesses through the application of good and sustainable crop cultivation techniques while maintaining local wisdom, and returning enthusiasm farmers so that they are interested again in managing their cocoa plants seriously and making cocoa plants a promising crop to increase the economy and people's income through counseling and demonstration activities on cocoa cultivation. The activities carried out included lectures and discussions, handing over superior cocoa seedlings, practicing how to transfer or planting cocoa seedlings to the field, and practicing how to care for cocoa plants.

Abstract: Robusta coffee is a leading commodity in Lima Puluh Kota Regency and is highly sought after by the public. However, farmers still sell more cherry coffee than green beans. The purpose of this study was to describe the problems faced by coffee farmers in Situjuah Limo Nagari District, who sell more cherry coffee than green beans, and to design a marketing strategy for green beans in Situjuah Limo Nagari District. This research was conducted from July to October 2025 in Situjuah Limo Nagari District. The location was chosen because there are farmers selling green beans or cherry coffee in Situjuah Limo Nagari District. The research sample was purposive, selecting coffee farmers selling green beans or cherry coffee. The analysis used descriptive qualitative methods involving robusta coffee farmers and the local government. The results of the study indicate a marketing strategy for developing robusta green beans, starting from the upstream stage (good cultivation practices), coffee processing machines, the need for local government support for expanding the marketing of robusta green beans, and digital marketing through social media and online stores. Keyword: robusta coffee; marketing; green beans. Abstrak: kopi robusta menjadi komoditas unggulan di Kabupaten Lima Puluh Kota dan banyak diminati masyarakat. Akan tetapi, petani masih banyak menjual kopi ceri dibandingkan kopi green bean. Tujuan dari penelitian ini adalah mendeskripsikan permasalahan petani kopi Kecamatan Situjuah Limo Nagari yang lebih banyak menjual kopi ceri dibandingkan kopi green bean  dan merancang pengembangan pemasaran kopi green bean di Kecamatan Situjuah Limo Nagari. Penelitian ini dilaksanakan pada Juli-Oktober 2025 di Kecamatan Situjuah Limo Nagari. Penentuan lokasi karena Kecamatan Situjuah Limo Nagari ada petani yang menjual kopi green bean atau ceri. Penentuan sampel penelitian dengan purposive yaitu petani kopi yang menjual kopi green bean atau ceri. Analisis yang digunakan deskriptif kualitatif melibatkan petani kopi robusta dan pemerintah daerah. Hasil penelitian menunjukkan perancangan pengembangan pemasaran kopi robusta green bean dengan yang dimulai dari hulu (cara budidaya yang baik), mesin pengolah kopi, perlunya dukungan pemerintah daerah untuk perluasan pemasaran kopi robusta green bean hingga pemasaran secara digital melalui media sosial dan toko online. Kata kunci: kopi robusta; pemasaran; green bean.

Abstract

Penelitian ini bertujuan untuk menganalisis aliran filsafat idealisme, pragmatisme, dan eksistensialisme dalam pembelajaran dengan menggunakan bahan ajar robotika berbasis Project Based Learning (PjBL) dengan memanfaatkan mikrokontroler Arduino UNO dan sampah anorganik sebagai media pembelajaran kreatif pada materi listrik arus searah (DC). Pendekatan filsafat pendidikan digunakan untuk meninjau aspek idealisme, pragmatisme, dan eksistensialisme dalam penerapan model ini, sehingga pembelajaran tidak hanya bersifat teknis, tetapi juga bermakna secara filosofis bagi pengembangan potensi siswa. Penelitian ini adalah penelitian kualitatif dengan pendekatan penelitian refleksi diri (Self-Reflective Research). Data penelitian diperoleh melalui data reflektif dan data introspektif. Data tersebut kemudian dianalisis secara tematik reflektif untuk menemukan makna filosofis penerapan model PjBL berbasis robotika dalam konteks idealisme, pragmatisme, dan eksistensialisme. Data menunjukkan bahwa pembelajaran fisika menggunakan bahan ajar robotik berbasis PjBL dengan kombinasi Arduino UNO dan sampah anorganik terbukti efektif meningkatkan ketrampilan abad 21 siswa MAN 3 Kota Jambi. Berdasarkan hasil analisis, secara filosofis keberhasilan ini mencerminkan perpaduan tiga aliran utama pendidikan yaitu secara idealisme dapat menumbuhkan rasionalitas, nilai moral, dan keindahan berpikir, dimana siswa belajar berpikir logis, teratur, dan bermakna. Secara pragmatisme, menekankan pembelajaran melalui pengalaman nyata (learning by doing), dimana siswa menemukan pengetahuan melalui praktik langsung, pemecahan masalah, dan kolaborasi. Secara eksistensialisme dapat memberi ruang bagi kebebasan berekspresi, tanggung jawab, dan pencarian makna pribadi dalam belajar. Secara keseluruhan, pembelajaran robotik berbasis PjBL ini bukan hanya mengajarkan konsep fisika dan teknologi, tetapi juga membentuk manusia yang berpikir kritis, kreatif, peduli, dan reflektif, selaras dengan tujuan filsafat pendidikan untuk menciptakan pembelajar yang utuh secara intelektual, moral, dan eksistensial.
