Abstract

The Universitas Pahlawan Tuanku Tambusai (UPTT) campus allows it to become a preferred habitat for mosquitoes while laying their eggs. Aedes sp. is a vector for the spread of Dengue Hemorrhagic Fever (DHF). One way to control dengue fever is to use insecticides. The use of insecticides that are excessive and repeated can have a negative impact, for that we take advantage of the potential of nature as a bioinsecticide. One of them is the lemongrass plant which can be used as a mosquito repellent because it contains substances such as geraniol, methyl heptenone, terpenes, terpenes, organic acids and especially citronella as a mosquito spray. This research is a quantitative research with a pure experimental design. Researchers made observations in the field to collect mosquito larvae, which were then reared in the laboratory. The results of rearing mosquitoes were then treated and analyzed using WHO mosquito mortality standard criteria. Lemongrass plants can be used as bioinsecticides or insect organic insecticides, for example the Aedes sp. Lemongrass plant extract (Cymbopogon citratus) is effective in killing Aedes sp. mosquito larvae. along with increasing concentration in each treatment. The most potent or effective concentration in killing Aedes sp. is a concentration of 20%.

Abstract

Rayap adalah serangga sosial yang hidup dalam suatu komunitas yang dikenal dengan istilah koloni. Aktivitas rayap sebagai hama pada tanaman perkebunan, pertanian, kehutanan, maupun pada bangunan gedung terjadi ketika habitat alami mengalami perubahan cukup drastis yang menyebabkan spesies rayap tertentu harus menyesuaikan diri terhadap perubahan tersebut. Salah satu jenis tanaman perkebunan yang dapat terserang rayap adalah tanaman karet. Tujuan Penelitian adalah untuk mengetahui jenis-jenis spesies rayap di perkebunan karet di desa Naga Beralih Kecamatan Kampar Utara Kabupaten Kampar, Riau. Pengumpulan rayap dilakukan di tiga transek di perkebunan karet di desa Naga Beralih. Transek sepanjang 100 m dan setiap transek dibuat 10 subplot (1 m x 1 m) dengan interval 10 m. Rayap dikumpulkan dengan menggali masing-masing subplot hingga kedalaman 10 cm. Terdapat enam spesies rayap yang ditemukan yaitu Bulbitermes sp., Nasutitermes sp., Capritermes sp., Macrotermes sp., Schedorhinotermes sp dan Coptotermes sp.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh intensitas cahaya matahari terhadap pertumbuhan dan perkembangan tanaman pakcoy (Brassica rapa L.) dengan menggunakan sistem hidroponik di lingkungan perkotaan. Metode yang digunakan adalah hidroponik tipe NFT (Nutrient Film Technique), dengan tahapan meliputi penyemaian benih pada rockwool, pemindahan ke sistem NFT, serta pemberian nutrisi AB Mix. Penelitian dilakukan di lingkungan kampus Universitas Pahlawan Tuanku Tambusai, Kabupaten Kampar, selama November 2023 hingga Februari 2024. Pengamatan dilakukan terhadap parameter tinggi tanaman, lebar daun, jumlah daun, dan berat tanaman. Hasil penelitian menunjukkan bahwa intensitas cahaya matahari berpengaruh terhadap pertumbuhan pakcoy, dengan pertumbuhan terbaik ditemukan pada tanaman yang mendapat paparan sinar matahari langsung. Media hidroponik memberikan keuntungan karena menghasilkan tanaman yang bersih dan sehat tanpa penggunaan pestisida. Penelitian ini diharapkan menjadi contoh penerapan pertanian modern yang dapat dikembangkan di lingkungan masyarakat. Disarankan untuk melakukan penelitian lanjutan dengan variasi intensitas cahaya dan konsentrasi nutrisi yang lebih tinggi guna memperoleh hasil yang lebih optimal.

Abstract

In the Sialang Sakti Village, Pekanbaru City, there is a group of women that used to conduct a household scale fish culture activities specifically catfish nursery (Pangasius hypopthalmus). Most of them using a simple earthen pond. They did not apply any modern technique in culturing the fish. To improve the ability of the women community in culturing fish, a dissemination of environmental friendly fish culture technique was conducted specifically catfish nursery. Slides and a simple manual book for catfish nursery in fish culture was used during the training. The community were also trained to construct tarp ponds, feeding, rearing and managing the water quality in the pond. Twenty five women that were belonged to “PKK” group attended the training. Before the training, their knowledge on fish nursery was very low, but after the training, their knowledge improved by 85%. Results of monitoring and evaluation activities shown that the women from the PKK group were able to catfish nursery with simple earthen pond and sustainable.

Abstract

Household waste is an environmental problem that has the potential to be very dangerous if alternative solutions are not found to reduce it. One of the household wastes that is often found is egg shells. This waste is often found in cake sellers, restaurants, households and laying hen farms. This waste is often found in cake sellers, restaurants, households and laying hen farms. Generally, Indonesian egg shells have not been managed properly so people only throw them away or store them in empty areas in village areas. The aim of community service is 1) a solution for managing egg shells as organic fertilizer, 2) Providing training regarding the use of egg shell waste as organic fertilizer. The method used is direct outreach and training with the vegetable cultivating community. The materials used are cassava leaves, animal waste, fruit waste, EM4 and palm sugar. The results of community service activities for vegetable cultivators show good results. The organic fertilizer solution that has been mixed with various other supporting materials is then put into a bottle and tightly closed, then fermented for up to 10 days at a temperature of 40°C. After 10 days, liquid organic fertilizer is put into packaging bottles. The organic fertilizer produced can be used directly by the cultivating community.
