The biopore infiltration hole is a hole with a diameter of 10 cm - 30 cm with a depth of 30 cm - 100 cm which is added with organic waste and will help soil biota form a biopore hole so that it can trap the air flowing around it. Black Soldier Fly larvae are able to accelerate composting and ordering of pores in the biopore infiltration holes. Perumahan Putri Indah Kulim RT 02 RW 12 Kelurahan Mentangor rarely finds open land semisization and house widening which causes a reduction in the surface of ground air infiltration so that during the rainy season puddles easily occur and during the dry season it reduces groundwater reserves. This activity aims to provide knowledge and insight into the community about biopore infiltration holes by utilizing Black Soldier Fly larvae and inviting the public to apply this technology. This service activity begins with the socialization of the biopore infiltration holes, then introduces the tools and materials as well as direct practice in the field. The results of this activity had a positive influence on the community and many community members who wanted to apply the biopore infiltration hole technology using Black Soldier Fly larvae. This is the first step in creating a clean and healthy environment, especially in Putri Indah Kulim Housing RT 02 RW 12 Mentangor Village.

The cassava's production arm was quite abundant. Human ratings generally revolved around plantations and in rungs industries, much of which was said in cassava commodities. Most people consume cassava in the simple way of being boiled, fried, made in chips, and so on. In order not to dull the flavor of traditional foods but to be increasingly ogled by the styrofoampurvets, it is possible to make the products of the Singkong processed innovation into cassava frozen. The public's devoted activity is to helping people improve the economy, providing added insight and skill to processing cassava through cassava frozen and helping people form a group of tapioca women (KWT). The method used in this dedicated activity is by counseling between socializing and training and by demonstrations of Singkong frozen production. This activity involves women of family welfare development and housewives in three neighborhood associations is number 01, 02, and 03 at citizens association 12, Mentangor village districts,Tenayan Raya city districts. The result of this activity is that the target public seems enthusiastic about the material presented and has increased participants' knowledge and insight on assava frocenas are 100%.

Fly ash merupakan salah satu produk sampingan dari pabrik kelapa sawit. Silika yang diekstraksi dari fly ash dapat dimanfaatkan untuk sintesis ZSM-5 dengan metode hidrotermal setelah pra-perlakuan fusi dengan NaOH. Penelitian ini bertujuan untuk mendapatkan ZSM-5 dan mengetahui karakteristik ZSM-5 yang disintesis. Sintesis dilakukan pada berbagai komposisi perbandingan molar SiO2/Al2O3 dengan penambahan PEG-400 sebagai template pada suhu 100 °C selama proses hidrotermal. Analisis menggunakan XRD menunjukkan bahwa dua dari tiga zeolit ​​yang disintesis adalah ZSM-5 dengan kristalinitas 67,63% dan 28,53%. Analisis menggunakan spektroskopi FTIR pada ZSM-5 yang disintesis mendeteksi banyak gugus termasuk gugus hidroksil T-OH (Si-OH/Al-OH), gugus TO (O-Si-O/O-Al-O) dan gugus pentasil yang khas dari ZSM -5. Dari analisis menggunakan adsorpsi piridin, dapat disimpulkan bahwa peningkatan rasio SiO2/Al2O3 menyebabkan jumlah sisi asam total sampel meningkat
