ABSTRACT This research purposes know the growth and tubers yield of potato (G0) under various thickness of cocopeat media and time of sundstrom nutrient giving. The research was carried in the screen house in Pandansari, Paguyangan district from October 2014 until January 2015. The research used Randomized Complete Block Design with 2 factor and 3 repetitions. The first factor was the thickness of media with three levels; 10 cm, 15 cm, and 20 cm. The second factor was the time of nutrient solution giving with two levels; once for three days and once for six days. The results of the research showed that the thickness of cocopeat media 20 cm was good for plant height, total of leaves, wide of plant leaves, and improve the roots length 23.6 %. Time of nutrient giving once for three days was good for plant height, total of leaves, wide of plant leaves, weight of fresh plant, weight of dry plant and the result was good for stolon effectiveness (49.84%), weight of fresh tuber (137.85 g), and weight of dry tuber (21.55 g). The treatment of cocopeat medium thickness and time of nutrient giving had not been able to provide increased yield of potato tuber (G0).

Maize roots will show varying growth responses to the type of fertilizer given. The objective of this study was to determine the effect of N, P, and K fertilizers on the growth of maize roots and the function of the relationship between root dry weight and shoot dry weight of maize under rizhotron. The research was conducted in April - June 2019 at the screen house and Plant Laboratory, Politeknik Lamandau in Lamandau Regency. The research was conducted in rizhotron's growth medium which was arranged in a completely randomized design (CRD) with a fertilizer treatment consisting of urea (N = 200 kg ha-1), SP36 (P = 100 kg ha-1), KCl (K = 100 kg ha-1), and control (without fertilizer) with three replications. The results showed that N fertilizer was able to provide better root dry weight growth compared to P and K fertilizer, namely 2.59 g. Root dry weight has a significant effect on plant dry weight gain based on the function of y = 4.10x + 0.06 (R2 = 0.96 **).

Nanga Bulik merupakan salah satu dari kelurahan di Kecamatan Bulik Kabupaten Lamandau, yang jumlah penduduknya tergolong tinggi dibandingkan kelurahan atau desa lainya di kabupaten lamandau, karena berada di ibu kota Kabupaten Lamandau. Salah satu permasalahan yang sering muncul pada daerah padat penduduk adalah penanganan sampah. Sampah menjadi permasalahan serius yang harus segera ditangani untuk menjadi desa atau kelurahan percontohan zero waste di Kabupaten Lamandau, sehingga diperlukan strategi dan inovasi untuk menjadi solusi dalam masalah tersebut. Salah satunya dengan menerapkan aplikasi bank sampah. Dengan adanya aplikasi bank sampah tersebut maka dapat meningkatkan manajemen pengelolaan sampah lebih efektif dan efisien di Kelurahan Nanga bulik, sehingga menjadi peluang untuk menjadikan daerah zero waste dan meningkatkan kepedulian masyarakat terhadap kebersihan lingkungan. Sistem aplikasi bank sampah ini digunakan sebagai manajemen atau pengolahan data oleh penyetor sampah, dan penyetor akan mendapatkan saldo berupa uang dari hasil pengumpulan sampah yang disetorkan, akan tetapi uang tersebut dikumpulkan dan disimpan pada database aplikasi bank sampah dalam bentuk saldo. Penyetor akan memiliki saldo hasil pengumpulan sampahnya. Pada pengabdian masyarakat ini telah diterapkannya sebuah aplikasi bank sampah untuk pemnfaatan dan pengolahan bank sampah yang konvensional menjadi lebih modern karena warga atau nasbah dapat dengan mudah mendapatkan informasi yang berkaitan dengan bank sampah tersebut.

The scarcity of compound fertilizer that often occurs on the market has caused farmer members who are members of the Bangun Bersama farmer group, Mekar Mulya Village, Sematu Jaya District, Lamandau Regency, Central Kalimantan Province to experience problems applying fertilizer to the oil palm plants they cultivate. In addition, limited information causes a lack of knowledge of members regarding other alternatives that can be used to overcome the scarcity of compound fertilizers, one of which is the single fertilizer mixing technique. The purpose of this service is to improve the skills of the members of the Bangun Bersama farmer group in making mixed fertilizer sourced from a single fertilizer which has an elemental content equivalent to the compound fertilizer recommendation. The service method used is training with lectures and work demonstrations of mixing fertilizers using a single fertilizer containing elements of N, P, K and Mg as well as monitoring the implementation of the training. Based on the results of the PkM activities carried out, it generated new knowledge for the Bangun Bersama farmer group in terms of utilizing single fertilizers into compound fertilizers using mixing techniques.

Oil palm is one of the world's strategic plantation commodities. Palm oil production continues to increase, which has implications for the increase in the amount of palm oil waste produced. One of the efforts to realize a sustainable palm oil program is by properly managing palm oil waste. Processing palm oil waste such as fronds, replanting trunks, and empty palm oil bunches with the pyrolysis method is one of the environmentally friendly waste processing. The use of the right method on each palm oil waste biomass determines the quality of the biochar produced. This study uses frond waste, replanting trunks, and empty palm bunches as raw materials for making biochar using pyrolysis methods, namely the manual method and Klin Retort. This study aims to determine the appropriate pyrolysis method to use through observation of the chemical characteristics of palm oil waste biochar. The results showed that the best chemical characteristics of palm oil waste biochar were in the Retort Klin method with a pH value and percentage of ash content, N-total, P-total, K-total, C-organic respectively of 7, 96, 4.86%, 0.47%, 0.04%, 0.96%, 50.18 on frond biochar, 7.42, 3.97%, 7.42%, 0.17%, 0.04%, 0.7%, 49.52% on replanting trunk biochar, and 6.31, 7.18%, 0.91%, 0.03%, 0.67%, 58.04% on oil palm empty bunch biochar.
