Abstract

Organic waste comprises a considerable portion of global waste, requiring effective management. The ability of the black soldier fly (Hermetia illucens, BSF) to convert organic waste into biomass has been well reported. However, bioconversion can be hindered by fiber-rich substrates, a challenge that can be addressed through substrate pretreatment. This study examined the oviposition preferences and larval performance of BSFs in several fruit wastes fermented by effective microorganisms (EMs), which were compared to non-fermented substrates. The oviposition attractants utilized pineapple peel and overripe soursop, with larval performance evaluated among different treatments, i.e., non-fermented pineapple peel (NFP), fermented pineapple peel (FP), non-fermented pineapple peel plus coconut endosperm waste (NFPC), and fermented pineapple peel plus coconut endosperm waste (FPC). Measured parameters included larval biomass, substrate consumption, the waste reduction index (WRI), and adult emergence. The result indicated that fermented pineapple peel produced the highest number of eggs among the oviposition attractant treatments. Larval biomass was highest in FP, while substrate consumption, WRI, and adult emergence rates were comparable between FP and FPC. Overall, the fermented substrates outperformed the non-fermented substrates across all parameters. These findings confirmed that fermentation with EMs enhances the utilization of fruit waste as an oviposition attractant and improves the performance of BSF bioconversion.

Abstract

Penggunaan insektisida sintetik memiliki keuntungan, namun juga mempunyai efek yang merugikan/berbahaya terhadap kesehatan manusia maupun lingkungan. Salah satu alternatif yang dapat ditawarkan adalah penggunaan biopestisida. Biopestisida lebih aman terhadap manusia dan lingkungan karena mudah terurai. Potensi biopestisida sangat besar di Indonesia yang kaya akan beraneka ragam tanaman yang tersedia sepanjang tahun. Tujuan kegiatan ini mensosialisasikan biopestisida kepada masyarakat cara membuat dan mengenal tanaman yang dapat digunakan, untuk mengurangi bahaya insektisida sintetik. Sosialisasi dan kunjungan ke Kebun Percobaan Balittro, Laing Solok, penyuluhan dan praktek langsung pembuatan biopestisida sederhana dari tanaman lokal. Beberapa tanaman lokal berpotensi sebagai biopestisida. Biopestisida sederhana dapat diekstrak dengan air dan penambahan sabun/deterjen. Contoh tanaman yang dapatkan digunakan sebagai biopestisida Toona sureni, Evodiaa suaveolens, Lantana camara, Geranium spp., Tagetes patula, Andropogon nardus dan lain-lain.

Abstract

Kota Padang salah satu daerah endemis Demam Berdarah (DB), dimana tidak ada satu kecamatanpun bebas dari demam berdarah. Pada tahun 2014, di Kota Padang terjadi 660 kasus demam berdarah dengan 6 kasus kematian. Satu tahun berikutnya, 2015 terjadi peningkatan kasus DB hampir dua kali lipat dari tahun sebelumnya. Penyakit ini disebarkan oleh nyamuk dari jenis Aedes aegypti dan Aedes albopictus yang aktif pada pagi dan siang hari menjelang sore. Jadi kedua nyamuk ini dikenal sebagai vektor penyakit DBD. Terkait dengan hal itu semua, perlu diterapkan pendekatan terpadu terhadap pengendalian nyamuk vektor ini. Salah satunya adalah dengan metoda “Ovitrap”. “OVITRAP” berarti perangkap telur, merupakan metoda sederhana namun standar WHO yang digunakan dalam memantau kepadatan populasi nyamuk. Metoda ini sudah umum digunakan dalam penelitian-penelitian baik nasional maupun internasional. Prinsip metoda ini adalah membuat perangkap agar nyamuk bertelur pada perangkap tersebut, kemudian secara berkala seminggu sekali keberadaan jentik nyamuk kita cek keberadaanya. Supaya telur atau larva nyamuk yang sudah terperangkap tidak menjadi dewasa. Apabila metoda ini dilakukan maka akan mampu menekan populasi nyamuk dan akan berkorelasi dengan resiko penyebaran penyakin demam berdarah.

Abstract

This activity is motivated by concern for the facts of climate change occurring globally and regionally. In response to this, the Indonesian government has also taken a number of concrete steps in all aspects of climate change adaptation and mitigation, both at the local, regional, and national levels. One national program that directly touches local communities is the climate village program known as "PROKLIM." The city of Bukittinggi has responded actively to this national program and has received national awards for the achievements of its activities in two community groups. The purpose of community service activities in the Climate Village Program is to increase the group's capacity in processing household organic waste through the application of Maggot cultivation from black soldier fly (BSF). The main methods of implementing the activities are training, providing assistance and companiment the target group. The activity results showed that the target group had the knowledge and skills to cultivate BSF and produce larvae/maggots. The target group had been able to produce fish/livestock feed from the larvae and developed plans to use the business results for the commercial market. One thing that becomes the next challenge is how to build continuity of feed availability for the maggot caterpillars, especially from household organic food leftovers in the group members' environment. In conclusion, the application of organic waste processing technology with maggot caterpillar cultivation is very potential to overcome the problem of waste in their neighborhood so that it can then be applied more widely in the city of Bukittinggi, to be able to overcome the problem of urban organic waste.

Abstract. Nazar YE, Hasmiwati, Rahayu R. 2025. Acetylcholinesterase activity and Ace-1 mutation in Aedes aegypti resistance to temephos. Biodiversitas 26: 4598-4605. An organophosphate insecticide called temephos is frequently used to manage Aedes aegypti, the main Dengue Fever (DF) vector. However, prolonged and widespread application has led to resistance in many mosquito. This study aimed to assess temephos resistance in Aedes aegypti larvae from Tanjung Bingkuang, Solok District, West Sumatra, Indonesia, using biochemical and molecular assays, this study sought to ascertain the resistance status of Ae. aegypti larvae collected from Tanjung Bingkuang, Solok District, West Sumatra. The biochemical test results showed that the larvae exhibited a high level of resistance, with an Activity Value (AV) of 1.077 and Acetylcholinesterase (AChE) enzyme activity of 6.65 U/L. Further molecular analysis identified a point mutation at codon T506T in the Ace-1 gene, characterized by a nucleotide change from ACA to ACT. Molecular analysis identified a synonymous mutation (T506T; ACA ? ACT) in the Ace-1 gene, potentially associated with resistance development. These results confirm the emergence of temephos resistance in local Ae. aegypti populations and highlight the importance of incorporating molecular and enzymatic surveillance tools into vector control programs to ensure larvicide efficacy. This study confirms that the use of the organophosphate insecticide temephos is no longer effective in controlling Ae. aegypti larvae in Tanjuang Bingkuang, Solok District, West Sumatra, Indonesia.

Abstract

Padang City produces over 660 tons of waste each day, and more than 60% of it is organic. Most of this ends up at the Air Dingin landfill, which has long exceeded its capacity and still operates through open dumping. While Black Soldier Fly (BSF; Hermetia illucens) larvae have attracted growing research attention as an organic waste processor, studies combining BSF bioconversion with biodrying (TOSS) and digital market development within a single community-scale program are scarce. This study reports the implementation and evaluation of such an integrated program, carried out with the Smarkgood Farmer Group in Kota Padang. Working through a participatory action framework, the team executed five sequential stages: partner identification, knowledge dissemination, technical training, technology application, and field mentoring. Key interventions included constructing BSF biopond units, providing a waste shredder calibrated to optimal larval substrate size, introducing the TOSS biodrying method for residual organic material, building a waste supply partnership with the Padang BSF Maggot Association (Agodang), and guiding the group through e-commerce onboarding. Following these interventions, the group operated a more functional and productive facility, maintained a stable organic waste supply, and actively sold products through online platforms. This program illustrates how science-based bioconversion technology, waste valorization, and digital market access can be combined into a community model that is practically transferable to other urban settings facing similar waste pressures.

Abstract

Plants of the Brassicaceae family display a highly complex and adaptive chemical defense system against biotic stresses, particularly herbivore attack. These defense mechanisms are physiologically based on the biosynthesis and activation of secondary metabolites, mainly glucosinolates, which are converted into toxic compounds such as isothiocyanates by the enzyme myrosinase upon tissue damage. This response is not only local, but also systemic, involving cross-interactions between roots and leaves, and is modulated by the hormones jasmonate (JA), salicylate (SA), and ethylene (ET). These complex interactions form a plant defense system that can be explicitly induced depending on the type and sequence of herbivore attack. In addition, molecular adaptation strategies, such as MYB gene expression, and engineering technologies, such as CRISPR/Cas9, have opened up opportunities to improve plant resistance. This study aims to analyze the physiological dynamics of Brassicaceae defense mechanisms, evaluate the role of hormonal and genetic regulation in enhancing plant resistance, and address the critical challenges posed by specialist herbivore adaptations and the socio-environmental implications of genetic engineering. By synthesizing these elements, this article presents a comprehensive review of the potential of these defense systems in advancing sustainable agriculture and promoting human health.
