Abstract

Keuntungan penggunaan pestisida nabati untuk mengendalikan hama pada tanaman adalah murah, mudah, ramah lingkungan dan tidak meninggalkan residu. Penelitian ini bertujuan untuk mengetahui efektivitas penggunaan ekstrak campuran daun Sirsak (Annona muricata L.), daun Tembakau (Nicotiana tabacum L.) dan deterjen sebagai pestisida nabati terhadap pencegahan dan pemberantasan hama belalang pada semai Jati (Tectona grandis L.f.) dan mengetahui tingkat kerusakan akibat serangan hama belalang pada semai Jati (T. grandis L.f.). Penelitian dilaksanakan di Persemaian Politeknik Pertanian Negeri Samarinda. Ada tiga perlakuan yaitu kontrol, pencegahan dan pemberantasan dengan empat konsentrasi ekstrak campuran daun Sirsak (A. muricata L.), daun Tembakau (N. tabacum L.) dan deterjen sebagai pestisida nabati yaitu 0 %; 0.5%; 1.0% dan 1.5%. Hasil penelitian menunjukan pertambahan konsentrasi ekstrak campuran pestisida nabati campuran daun Sirsak (A. muricata L.), daun Tembakau (N. tabacum L.) dan deterjen berbanding lurus dengan persentase kematian hama belalang. Adapun frekuensi semai jati yang terserang hama belalang dan intensitas serangan hama belalang menunjukkan sebaliknya.

Abstract

Weeds growing wild among the staple crops cultivated by farmers have become a serious problem and must be immediately controlled, especially in forestry, agricultural and plantation areas. Therefore, practical knowledge is needed about how to manage the problem of weeds that grow undesirable and how to overcome them. Non-chemical weed control is carried out with physical activity. Physical activity carried out by workers while working is a physical workload that will affect their work productivity. The weight or lightness of work done by workers can be measured through direct measurements of human limbs or physique, among others, heart rate, blood pressure, body temperature, sweat rate, consumption of inhaled oxygen and chemical content in the blood. This study aims to identify the use of semi mechanical weed tools and brush cutter as well as analyze the physical workload experienced by workers. The stages and methods of research are carried out by measuring and testing tools in the field based on technical aspects including theoretical work capacity, effective work, field efficiency, fuel consumption, while ergonomic work aspects by measuring workload and fatigue levels directly on the operator's heart rate. From the measurement and calculation of the Increase Ratio of Heart Rate (IRHR), the lowest workload level was obtained with an index of 1.15 and the highest workload level of 1.51.

Abstract

Kaliandra (Calliandra calothyrsus Meisn) is a plant capable of producing large amounts of biomass, potentially as a renewable energy source that supports the reduction of dependence on fossil fuels. The transition from fossil fuels to renewable energy is an urgent and long-term solution, as the use of fossil fuels as an energy source contributes to global warming and climate change.This study aims to evaluate the effect of compost fertilizer dosage and compost tea on the growth of height and diameter of kaliandra seedlings. Using a one-factor complete randomized design (CRD) method with treatment of compost fertilizer doses K0 (0 grams), K1 (60 grams), K2 (75 grams) and K3 (90 grams) and compost tea doses TK1 (0 ml), TK1 (50 ml), TK2 (75 ml) and TK3 (100 ml). Research results: 1. The treatment of compost doses and compost tea showed significant differences in the height growth of calliandra seedlings. 2. Compost fertilizer with a dose of 90 grams (K3) showed a better height growth rate than compost tea fertilizer with a dose of 100 ml (TK3), 75 ml (TK2), and 50 ml (TK1). 3. Compost tea fertilizer with doses of 50 ml (TK1) and 75 ml (TK2) showed a better height growth rate than compost fertilizer with doses of 60 grams (K1) and 75 grams (K2). 4. The compost fertilizer dose treatment showed a significant difference in the growth rate of Calandra seedling diameter, while the compost tea dose treatment did not show a significant difference. 5. Compost fertilizer with doses of 75 grams (K2) and 90 grams (K3) showed better diameter growth than compost tea fertilizer with doses of 75 ml (TK2) and 100 ml (TK3). 6.  The optimal dosage recommendation in this study is 90 grams of compost fertilizer and 75 ml of compost tea.

Abstract

Environmental conditions and community activities impact surface water and groundwater quality. Physical, chemical, and biological parameters can be used to assess water quality so that i can be used by established quality standars. This study aimed to assess the quality of surface water and groundwater around the Samarinda State Agricultural Polytechnic using TDS, pH, COD, Fe, and Zn parameter sat eight different sampling locations. Water quality assessment based on physical and chemical parameters follows the guidelines of Goverment Regulation No. 22 of 2021. Based on the research results, the TDS value range is 61 mg/L – 320 mg/L; the pH value range is 5,4 – 7,97; the COD value range is 136 mg/L – 208 mg/L; the Fe value range is between 21,4 mg/L and 27,3 mg/L, and the Zn value range is between 0,89 mg/L and 1,44 mg/L. This indicates that some water quality parameters, including COD, Fe, and Zn, do not meet the quality limits set by Government Regulation No. 22 of 2021.
