Abstract

The application of biopesticides is one of the safest alternatives to realize organic agriculture that does not cause harmful impacts to both consumers and the environment. This activity aims to apply biopesticides in eradicating fruit flies (Bactrocera sp.) on Sweet Orange (Citrus X Sinensis) plants. The partner location is the Bukit Rumah Sendi Farmers Group in Karo Regency. Eucalyptus grandis leaves were extracted using steam distillation then the concentration of 1,8 Sineol was determined using GCMS and the concentration was 52%. Eucalyptus oil was mixed with kerosene and detergent then determined the LC50 value in fruit flies and observed for 24, 48, 72, and 96 hours and produced an LC50 value of 35%. This shows that biopesticides are quite effective in eradicating fruit flies.

Abstract

The grafting degree of maleic anhydride onto cyclized natural rubber is generally still low. This is due to the lack of electron density of the maleic anhydride double bond so that its reactivity is low. This research aims to increase the grafting degree by the addition of a styrene comonomer. Grafting of maleic anhydride onto cyclized natural rubber had been performed in an internal mixer 150 oC and 80 rpm in the presence of styrene comonomer. The grafted product was analyzed by Fourier Transform Infra-Red to determine the presence of maleic groups and Differential Scanning Calorimetry and Thermalgravimetric to investigate its thermal properties. Fourier Transform Infra-Red spectra confirmed that the grafted product of maleic anhydride onto Cyclized Natural Rubber formed with absorption at 1700 cm-1, 1850 cm-1 and 700 cm-1. The higher concentration of maleic anhydride reacted the higher of grafting degree of maleic anhydride with the high intensity of absorption at 1700 cm-1 and 1850 cm-1. Differential Scanning Calorimetry spectra showed that the glass transition temperature of maleated Cyclized Natural Rubber products increases, the more comonomer are added the higher the glass transition temperature of the product. Generally, based on the Thermalgravimetric spectra, the thermal properties of grafted product does not change significantly compared to the blank sample.

Abstract

Devotion is an activity that is highly expected to be carried out well, because it can improve and add to knowledge and skills. The male students at the Al Quran memorization headquarters are the driving force to open up land that has not been utilized properly. The location of the land for strengthening food security that will be carried out is close to the location of the Al Quran memorization headquarters, making it easier to move to the land location. The beginning of this movement is land preparation or clearing land from undergrowth using tripe, machetes and hoe so that clean land is obtained and ready to be planted. The types of plants that will be planted in this food security strengthening are cassava, sweet potatoes or yams, corn, taro, peanuts and green beans.

Abstract

Nowadays, the number of orange juice business increases in Medan city. This business produces a byproduct that is discarded and not utilized by the seller. On the other hand,  many people living in poverty and less empower because they don't have the skills to generate additional income. This program wants to use zero-waste concepts to empowering a community. Zero Waste is one of the solutions to the problem of handling Waste as well as the empowerment of people. Partner of this program is people of Program family Harapan (PKH) incorporated in Kelompok Usaha Bersama (KUBE) Rezeki Jermal located in the village of Denai, Medan. Socialization and training is the method used in this program. Derivative products of essential oil are repellent lotion and aromatherapy candles. The final result of this program are partner know the implication of zero Waste and have the skill to manage the Waste.

Abstract

Indonesia menghadapi tantangan lingkungan akibat kepadatan penduduk dan perubahan fungsi lahan, sehingga program penghijauan seperti Taman Gizi menjadi penting untuk pelestarian alam dan peningkatan kesehatan masyarakat. Kegiatan ini dilaksanakan di Desa Rawang Pasar V, Asahan, dengan metode studi literatur, observasi, dan tahapan perencanaan, pengumpulan bahan, pembuatan, penanaman, serta evaluasi. Taman Gizi yang memanfaatkan pekarangan berhasil meningkatkan kesadaran masyarakat tentang gaya hidup sehat, ketahanan pangan, dan lingkungan yang lebih hijau. Selain meningkatkan pengetahuan dan perilaku kesehatan, kebun gizi juga memperkuat solidaritas sosial dan keterlibatan warga dalam pelestarian lingkungan. Dengan demikian, Taman Gizi berperan sebagai solusi strategis dalam menjaga ekologi dan kesejahteraan masyarakat

Abstract

Penelitian ini bertujuan menganalisis pengaruh pengetahuan halal, religiusitas Islam, dan sikap terhadap perilaku halal karyawan Generasi Z serta memberikan tingkat efisiensi pemanfaatan faktor ketiga tersebut dalam membentuk perilaku halal. Studi dilakukan pada 200 karyawan Generasi Z di PT. Siantar Top Tbk. Medan dengan pendekatan kuantitatif asosiatif. Analisis data menggunakan SEMPLS untuk menguji hubungan antarvariabel dan Data Envelopment Analysis (DEA) untuk mengukur efisiensi relatif responden. Hasil SEM-PLS menunjukkan bahwa pengetahuan halal (β = 0,239; p < 0,05), religiusitas Islam (β = 0,320; p < 0,05), dan sikap (β = 0,247; p < 0,05) berpengaruh positif dan signifikan terhadap perilaku halal. Nilai R² sebesar 0,545 menunjukkan bahwa variabel ketiga menjelaskan 54,5% variasi perilaku halal. Namun hasil DEA menunjukkan sebagian besar responden (66%) berada pada tingkat efisiensi menengah, sehingga masih terdapat kesenjangan antara potensi internal dan implementasi perilaku halal. Penelitian ini menegaskan bahwa penguatan budaya kerja halal tidak hanya memerlukan peningkatan pengetahuan, religiusitas, dan sikap, tetapi juga optimalisasi pemanfaatannya agar perilaku halal dapat terwujud secara konsisten dan berkelanjutan.
