Abstract

Oil palm (Elaeis guineensis Jacq.) Is a plant species that has good adaptability in various environments. As a well-adapted plant, palm oil is very tolerant of mismatches in its handling and its normal growth can recover quickly from stress due to planting movements, drought, fires and other disruptions. The saline soil is an unsuitable type of soil for the growth of oil palm crops. Utilization of humic acid as a mixed organic material for saline soil, humic acid in the soil can act as a source of nutrients, maintaining soil moisture, as a buffer by chlorizing the elements causing salinity to increase the availability of nutrients. The study was conducted in the nursery area. The study period was 5 months, from January to June 2017. This study used Factorial 2 with 3x replication, the number of polybags per treatment was 3. The parameters test were arranged on the real variance checklist, followed by continued analysis with Duncan Multiple Range Test (DMRT ) with a rate of 5%. The results showed that humic acid treatment on saline soil medium with DHL level ≥4 mmhos / cm can increase plant height growth, leaf area index, root volume, root dry weight and dry weight of crown.

Abstract

Oil palm initially produced Crude Palm Oil and Palm Kernel Oil as the main products of fresh fruit bunches, besides that currently the Indonesian palm oil industry utilizes the rest of the processing of fresh fruit bunches is waste as a soil enhancer. This study aims to determine the comparison of the total soil microbes, soil respiration, and the correlation between the two on the application. The research design used was a factorial randomized block design consisting of 2 factors. Factor I is the LCPKS application and factor II is the depth of soil sampling in the oil palm area. Parameters observed were total microbial and soil respiration. The results of observations are arranged in a variance table, if they are significantly different at the 5% level, then it is continued with the DMRT. The relationship between total microbes and soil respiration was analyzed by linear regression. The results showed that the total microbes were significantly different in the application land and without the POME application, the total microbes in the POME application area were higher than in the land without the application. but in the treatment of differences in soil depth there was no significant difference. The total microbial is positively correlated with soil respiration, the greater the total microbial, the higher the soil respiration.

Abstract

Watershed as an ecosystem has survival benefit for humans and other living organisms, in which there is forest that has many services, such as: water management, flood control soil erosion protection, soil fertility maintainance, nutrient preservation and environmental balance conservation. Sub watershed Lewara is one of the sub-watershed that provide water supply in the watershed area of Palu. However, reduction on vegetation cover along the riverbank of Lewara lead erosin and increased the run off which is also a cause sedimentation. This study aimed to calculate water discharge and sediment drift produced by sub watershed of Lewara at Balane Village, Sub district of Kinovaro. The method used in the study is a field survey and measurement directly water discharge and sediment at the field through determination of three points in the upstream, midstream, and downstream. The results of the study indicate that water discharge and drift sediment concentration in the study period that discharge of water with an average value of 1,8506 m3/s and drift sediment concentration with an average rating of 0,000081 g/l. Based on the results obtained indicate water discharge has a strong corelation with the drift sediment total with correlation value of 0.621, and a strong correlation of rainfall and drift sediment total with the correlation value of 0.699. This may be concluded that the increased rainfall would be followed by increased water discharge and drift sediment load concentration by river flows. Keywords: watershed, water discharge, drift sediment

Abstract

Limbah industri tahu merupakan masalah yang menjadi agenda di Margoagung, Seyegan, Sleman. Daerah ini merupakan sentra industri tahu di DIY. Melalui program Pengabdian Masyarakat (Abdimas) yang berkelanjutan sejak 2020 hingga sekarang Universitas Sarjanawiyata Tamansiswa (UST) memberikan edukasi lewat Kuliah Kerja Nyata dua tahun berturut-turut (2020-2021) dilanjutkan dengan penelitian dosen yang didanai Bappeda Sleman berhasil membentuk Rumah Maggot Barepan Bangkit (RMBB). Hal ini dilanjutkan dengan membentuk Kelompok Kampung Bangkit dengan program Program Insentif Pengabdian Masyarakat Terintegrasi dengan MBKM Berbasis IKU bagi Perguruan Tinggi Swasta tahun 2022 kerja sama Direktorat Riset, Teknologi, dan Pengabdian Kepada Masyarakat Kemdikbudristek, Fakultas Pertanian, Fakultas Teknik Industri, Fakultas Keguruan dan Ilmu Pendidikan UST. Kegiatan yang dilakukan adalah peningkatan kapasitas RMBB menjadi sentra pengolahan limbah tahu mandiri berbasis masyarakat, dengan mengajarkan dan pendampingan dalam pengolahan maggot menjadi pellet apung, pengolahan dan pengemasan kasgot menjadi pupuk dan media tanam, serta literasi numerasi bagi anak-anak dengan tujuan mencintai lingkungan dengan olah limbah mandiri. Pengabdian ini dibagi menjadi tiga tahap. Tahap pertama adalah sosialisasi tentang pemasaran digital dan kebun bergizi pada 16 Desember 2022 yang diikuti oleh warga RMBB dan anak-anak.Tahap kedua adalah workshop pengolahan maggot menjadi pellet dan pengolahan kasgot menjadi pupuk serta media tanam.Tahap ketiga adalah field trip ke Ombak Karangawang untuk belajar langsung Teknik pengolahan maggot menjadi pellet. Hasil akhirnya adalah dihasilkan produk yang bernilai jual, antara lain pupuk, maggot kering, dan pellet, serta kebun bergizi sebagai wahana literasi dan numerasi untuk meningkatan pengetahuan pengelolaan kebun bergizi sebagai sarana ketahanan pangan tingkat desa.

Abstract

Fire caterpillar (Setothosea asigna) is one of the leaf-eating pests in oil palm plantations, where this type of fire caterpillar is most commonly found in plantations and the highest level of attack. Sycanus annulicornis controls the population of fire caterpillars and to minimise the attack of fire caterpillar pests, as well as maintaining a stable population of fire caterpi llar pests in nature and reducing the use of chemical pesticides that can damage the environment. The purpose of this study was to determine the ability of S. annulicornis predators to control fire caterpillar pests. This research was conducted at the Indonesian Institute of Palm Technology Practical Field using the Randomised Group Design (RAK) method with DMRT further test. S. annulicornis predator was able to predate S. asigna caterpillars at the first time of application in treatme nts P1 (3 caterpillars), P2 (6 caterpillars), P3 (9 caterpillars) and P4 (12 caterpillars). The results showed that the longest searching time was recorded at 84.0 minutes and the fastest at 39.0 minutes, for handling time the longest time was 118 minutes and the fastest time was 51.0 minutes. Keywords: Setothosea asigna, , S. annulicornis, Predation Power INTISARIUlat api (Setothosea asigna) merupakan salah satu hama pemakan daun di perkebunan kelapa sawit, dimana ulat api jenis ini yang paling sering dijumpai di perkebunan dan tingkat serangannya yang paling tinggi.
